Utility model content

-Technical problems to be solved by the utility model-

As described above, when forming the hollow part of the mold forming part using a die, since a core member is used, a hole for core extraction is formed in a part of the peripheral wall of the hollow part. As a countermeasure against this, as described in Patent Documents 1 and 2, there is a method of sealing the hole for extracting the core with an adhesive, but this method causes the following problems.

That is, since the hole for extracting the core is a hole for extracting the core member after the mold forming part is formed, the hole for extracting the core is a slit having a predetermined width corresponding to the root thickness of the core. shape. Therefore, if it is to be blocked with an adhesive, one edge of the hole for extracting the core is joined to the other edge opposite to the edge. The edge portion approaches a predetermined width, and the hollow portion needs to be deformed, so that the shape and size of the hollow portion differ from the shape and size after forming.

Since the shape and size of the hollow portion affect the sealing performance, it is generally necessary to strictly set the shape and size. Therefore, if the proposals of Patent Documents 1 and 2 are adopted, predictive molding must be performed so that the shape and size of the hollow portion sealed with an adhesive are most suitable for ensuring sealing performance, resulting in the design of the shape of the molded portion. (making the design drawing of the shape) is complicated.

In addition, if an adhesive is used as in Patent Documents 1 and 2, it is necessary to apply the adhesive, thereby reducing work efficiency, and it is conceivable that the appearance of the weather strip may be affected due to the exposure of the adhesive. reduced sex. In this regard, in addition to the extruded weather strip main body disclosed in Patent Document 3, it is conceivable to separately provide a long plate-shaped mounting member. If the weather strip is an extruded product, the shape design of the molded part (creation of the design drawing of the shape) will not be as complicated as the problem in Patent Documents 1 and 2, but there are other problems described below, so it is not preferable. . The other problem is that since both the weather strip and the long plate-shaped mounting member have a straight shape, it is difficult to adhere to the surface with a small curvature of the vehicle body.

The utility model is completed in view of the above-mentioned problems, and its purpose is: instead of using the mounting part only for fixing the sealing strip, a part of the mounting part is also used to plug the hole for pulling out the core, so as not to It requires the work of sealing the hole for extracting the core with an adhesive, and the design of the weather strip including the hollow portion is facilitated.

-Technical solutions to solve technical problems-

In order to achieve the above object, the utility model forms a hole for extracting the center core on the surrounding wall of the hollow part, which is subjected to a compressive load when the door is closed, and inserts a part of the mounting part for fixing the weather strip into the center core. In the hole for pulling out, the hole for pulling out the center core can be blocked.

A slit-shaped core extraction hole is formed on a portion of the peripheral wall of the hollow portion that receives a compressive load when the door is closed. The center core extraction hole is used to form the core. The core member behind the inner surface of the hollow part is pulled out to the outside of the hollow part,

The attachment member has an insertion plate portion inserted into the core extraction hole, and the thickness of the insertion plate portion is set to be substantially equal to the opening width of the core extraction hole.

According to this configuration, when the molded part of the weather strip is fixed to the door by the mounting member, for example, if the door is closed, the hollow part of the molded part of the weather strip is compressed by the peripheral edge of the door and the opening of the vehicle body. elastic deformation occurs. At this time, since the insertion plate portion of the mounting member is inserted into the core extraction hole of the hollow portion and receives a compressive load, the core extraction hole is blocked by the insertion plate portion, and the core extraction hole The opening width is maintained due to the thickness of the insert plate. Furthermore, the thickness of the insertion plate portion is set in advance to be approximately equal to the opening width of the hole for core extraction, whereby the opening width of the hole for core extraction hardly changes from the opening width after molding. Therefore, it is not necessary to set the shape and size of the hollow portion based on prediction, as in the case of sealing with an adhesive in the conventional example.

In addition, since plugging can be performed by inserting the insertion plate portion into the hole for extracting the core, a plugging operation using an adhesive is not required, and deterioration of the appearance of the weather strip can also be avoided.

The utility model of the second aspect is like this, and in the utility model of the first aspect, it is characterized in that:

A locking hole is formed on a peripheral wall portion of the hollow portion,

The locking hole is formed on the curved wall portion.

According to this configuration, in a state where the base plate portion of the mounting member is arranged inside the hollow portion of the molded portion of the weather strip, the engaging protrusion of the mounting member penetrates through the fixing plate portion of the hollow portion and is inserted into the engaging hole of the door. to engage. Thus, the weather strip is fixed on the door. At this time, since the locking portion of the mounting member is locked in the engaging hole formed in the curved wall portion of the hollow portion, the center core extraction hole located between the curved wall portion and the fixed plate portion is reliably suppressed. wide open.

The utility model of the fourth aspect is as follows, and in the utility model of the third aspect, it is characterized in that:

The base plate portion of the mounting member is formed to extend along the fixing plate portion of the hollow portion,

That is, there is a portion of the door where it is difficult to form an engaging hole for attaching the component. In this case, the number of fixing points decreases, so a part of the fixing plate portion of the hollow portion may easily float from the door. However, in the present utility model, by locking the fixed plate portion side locking portion of the base plate portion of the mounting component to the fixed plate portion of the hollow portion, it is also possible to make the mounting component and the hollow portion a position other than the engaging hole. One. Thereby, the phenomenon that the fixing plate portion of the hollow portion is lifted is effectively suppressed by the mounting member.

The utility model of the fifth aspect is like this, and in the utility model of the fourth aspect, it is characterized in that:

A portion of the base plate portion where the locking portion on the fixing plate portion side is formed is formed further away from the fixing surface of the door than a portion of the base plate portion where the engaging protrusion is formed.

That is to say, the locking portion on the fixing plate side has a shape protruding from the base plate toward the door side, and according to the present invention, the amount of protrusion of the locking portion on the fixing plate side toward the door side can be reduced. Thereby, when fixing the weather strip, the locking part on the side of the fixing plate part hardly becomes an obstacle.

The utility model of the sixth aspect is as follows. In the utility model of the first aspect, it is characterized in that:

The insertion plate portion of the mounting member is formed to extend from a base plate portion of the mounting member disposed inside the hollow portion,

The thickness of the base plate portion is set to be larger than the thickness of the insertion plate portion.

That is, when the opening width of the hole for extracting the core is narrow, if the thickness of the insertion plate portion is set to be approximately equal to the opening width of the hole for extracting the core, the rigidity of the mounting member will decrease. There is even a possibility that the mounting strength of the weather strip may decrease. However, according to the present invention, since the thickness of the base plate part of the mounting part arranged inside the hollow part is greater than the thickness of the insertion plate part, even if the opening width of the core extraction hole is narrow, the mounting part can be sufficiently ensured by the base plate part. rigidity.

This eliminates the need for the conventional work of sealing the core extraction hole with an adhesive, and it is not necessary to set the shape and size of the hollow portion based on predictions, so that the design can be facilitated.

According to the utility model of the second aspect, since the locking portion of the mounting member is inserted into the locking hole of the peripheral wall portion of the hollow portion for locking, the mounting member and the peripheral wall portion of the hollow portion can be integrated to effectively suppress the The core extraction hole is open.

According to the third aspect of the invention, when the weather strip is fixed to the vehicle door, the locking portion of the mounting member is locked into the engaging hole formed in the curved wall portion of the hollow portion. Thereby, opening of the hole for core extraction can be suppressed reliably by an attaching member.

According to the fourth aspect of the utility model, since the locking portion on the side of the fixing plate portion that is locked to the fixing plate portion of the hollow portion is formed on the base plate portion of the mounting member, there is an engaging hole in the door that is difficult to form the mounting member. In the case where the number of fixing points decreases due to the part of the hollow part, it is possible to suppress the phenomenon that the fixing plate part of the hollow part floats up.

According to the fifth aspect of the utility model, since the portion of the base plate portion where the locking portion on the side of the fixing plate is formed is formed away from the fixing surface of the door, the amount of protrusion of the locking portion on the side of the fixing plate to the side of the door can be reduced. , it can be achieved: when fixing the sealing strip, the locking part on the side of the fixing plate part is not to be an obstacle.

Reference numeral 10a denotes an upper die forming portion, reference numeral 10c represents a middle die forming portion, reference numeral 10e represents a lower die forming portion, and reference numerals 10b and 10d represent extrusion forming portions.

Although not shown in the figure, the molded part 10c of the weather strip is obtained by a mold forming method in which a material is formed by using a mold. As shown only in FIGS. part 11 and lip 12. The hollow part 11 is in the shape of a strip extending continuously from one end, that is, the upper end, to the other end, that is, the lower end, of the sealing strip main body 10. The hollow part 11 is a part as described below, that is, as shown in FIG. 4 , A portion that contacts the body panel 200 when the rear door 100 is closed and is compressed by the rear door 100 and the body panel 200 to elastically deform as indicated by phantom lines in FIG. 4 . In the state where the external force has not yet acted, the cross-sectional shape of the hollow portion 11 in the horizontal direction is set to be long in the front-rear direction of the vehicle as shown in FIG. shorter.

The peripheral wall portion of the hollow portion 11 has a fixed plate portion 13 and a curved wall portion 14, and the fixed plate portion 13 extends substantially in the vehicle interior and exterior direction along a first plate portion 103a formed in the rear door. 100 , the fixing surface of the weather strip 2 is fixed. The curved wall portion 14 is connected to the fixing plate portion 13 and is bent away from the fixing plate portion 13 toward the rear side of the vehicle to contact the vehicle body panel 200 . The fixed plate portion 13 and the curved wall portion 14 are integrally formed.

The fixing plate portion 13 is partially in close contact with the first plate portion 103 a of the rear door 100 in a state of being fixed to the rear door 100 . The front edge portion of the fixed plate portion 13 reaches the front edge portion of the first plate portion 103a. On the front edge portion of the fixed plate portion 13, a protrusion portion 13a is formed that protrudes toward the outside of the vehicle and is approximately along the Extend up and down. The protrusion 13a is formed to extend along the front edge of the first plate portion 103a, and the front-rear direction of the weather strip main body 10 is positioned by the protrusion 13a. The rear edge of the fixed plate portion 13 is located in front of the second plate portion 103b and has a distance from the second plate portion 103b. Therefore, a gap is provided between the fixed plate portion 13 and the second plate portion 103b.

Further, as shown in FIG. 4 , fixing through-holes 13 b are formed in the fixing plate portion 13 so as to correspond to the formation positions of the engaging holes 103 d of the rear door 100 . Although only one fixing through-hole 13b is shown in FIG. 4 , two fixing through-holes 13b are formed at intervals in the vertical direction on the fixing plate portion 13 . These fixing through-holes 13b are inserted into engaging protrusions 23 of an attachment member 20 described later. In addition, as shown in FIG. 6, between the upper side fixing through hole 13b (shown in FIG. 4 ) on the fixing plate portion 13 and the lower side fixing through hole (not shown) on the fixing plate portion 13 A central through hole 13c is formed at the portion. A hook (fixed plate side locking portion) 24 of the mounting member 20 described later is locked in the middle through hole 13c.

As shown in FIG. 4 , the curved wall portion 14 is bent after extending from the front edge portion of the fixing plate portion 13 toward the vehicle rear side, and then extends toward the vehicle front side. The lip portion 12 is formed on the vehicle outer side of the curved wall portion 14 . This lip 12 extends towards the outside of the vehicle. The thickness of the curved wall portion 14 is set to be smaller than the thickness of the fixed plate portion 13 .

In the longitudinal direction of the hollow part 11, a plurality of locking holes 14a are formed at intervals from each other, and at least one of the locking holes 14a is arranged in the longitudinal direction of the hollow part 11 and the fixing through hole of the fixed plate part 13. 13b at the same position. Further, a protruding portion 14 b protruding outward from the hollow portion 11 and extending along the longitudinal direction of the hollow portion 11 is provided on the outer side of the vehicle than the locking hole 14 a of the curved wall portion 14 .

As mentioned above, since the mold-molded part 10c of the weather strip is a mold-molded product, when forming the hollow part 11, a mold for forming the outer surface of the hollow part 11 and a mold for forming the inner surface of the hollow part 11 (core member) are used. ), but these are not shown. The core member has an inner surface molding portion that shapes the inner surface of the hollow portion 11, and a support portion (corresponding to a root portion of the core member) for supporting the inner surface molding portion. Due to the support portion, when the core member is pulled out from the hollow portion 11, a slit-shaped center core extraction hole 30 will be formed on a part of the peripheral wall portion of the hollow portion 11 in the circumferential direction. The extraction hole 30 has an opening width corresponding to the thickness of the supporting portion. That is, the core extraction hole 30 is a hole for extracting the core member to the outside of the hollow portion 11 after the molded portion 10c of the weather strip is molded.

In the present embodiment, the hole 30 for extracting the core is formed in a portion of the peripheral wall portion of the hollow portion 11 that receives a compressive load when the rear door 100 is closed. That is, when the rear door 100 is closed, the hollow portion 11 is sandwiched between the rear door 100 and the vehicle body panel 200 as shown by phantom lines in FIG. , an external force acts to press the rear portion of the curved wall portion 14 against the fixed plate portion 13 . Therefore, when the rear door 100 is closed, the portions of the weather strip main body 10 that receive a compressive load are the rear side portion of the curved wall portion 14 and the rear side portion of the fixed plate portion 13 . The core extraction hole 30 is formed between the rear side portion of the curved wall portion 14 and the rear side portion of the fixed plate portion 13 . Therefore, one edge portion 30a of the hole 30 for core extraction is constituted by the rear portion of the fixed plate portion 13, and the other edge portion 30b is constituted by the protruding portion 14b of the curved wall portion 14. The hole 30 for core extraction has the following features: That is, when the rear door 100 is closed, the other edge portion 30b is displaced in a direction approaching the one edge portion 30a.

(Structure of mounting parts)

As shown by the dotted line in Fig. 3, the mounting member 20 is formed in a plate shape shorter than the hollow portion 11 so as to be provided only in a predetermined area in the longitudinal direction of the hollow portion 11, and the mounting member 20 is used to attach the weather strip The middle mold forming portion 10 c is fixed to the rear door 100 . As shown in FIGS. 7 to 9 , the mounting member 20 includes a substrate portion 21 , a locking portion 22 , an engaging protrusion 23 , and a hook 24 . As shown in FIG. 4 , the base plate portion 21 is arranged inside the hollow portion 11 and is formed to extend in a manner corresponding to the shape of the fixing plate portion 13 of the hollow portion 11 . As shown in FIG. 7 , the base plate portion 21 is curved in the same shape as the first plate portion 103 a of the rear door 100 . As shown in FIGS. 4 to 6 , an insertion plate portion 25 inserted into the core extraction hole 30 is formed on the base plate portion 21 . The insertion plate portion 25 is formed to extend from the edge in the width direction of the base plate portion 21, and the thickness of the insertion plate portion 25 is set to be equal to the opening width of the center core extraction hole 30 (one edge portion 30a and the other edge portion 30b The interval size) is roughly equal. The opening width of the core extraction hole 30 refers to the opening width in a state where no external force acts, and its dimension is substantially equal to the thickness dimension of the root portion of the core member.

In addition, the thickness of the insertion plate portion 25 is “approximately equal” to the opening width of the core extraction hole 30 including the case where the thickness of the insertion plate portion 25 is exactly equal to the opening width of the core extraction hole 30, and also Included is a case where there is a difference in size that can be called equal after taking into account molding errors that may generally occur when resin molding or rubber molding is performed as a vehicle part. For example, when the difference between the thickness of the insertion plate portion 25 and the opening width of the hole 30 for core extraction is within 5% of the thickness of the insertion plate portion 25, it can be said that the thickness of the insertion plate portion 25 and the opening width of the core extraction hole 30 are within 5%. The widths of the openings are substantially equal, and the functions and effects of this embodiment described later can be exhibited.

In addition, as shown in FIG. 4 , the thickness of the base plate portion 21 is set to be larger than the thickness of the insertion plate portion 25 . Thus, for example, when the opening width of the core extraction hole 30 is narrow and the thickness of the insertion plate portion 25 has to be reduced, the rigidity of the mounting member 20 can be increased by the base plate portion 21 . In addition, as shown in FIG. 4 and the like, a rib (rib) 21 a is provided on the surface of the vehicle inner side of the substrate portion 21 .

(Function and Effect of Embodiment)

Next, operations and effects of this embodiment will be described. Before fixing the weather strip 2 to the rear door 100, the mounting member 20 is assembled to the mold forming portion 10c in the weather strip. At this time, the mounting member 20 is inserted into the hollow portion 11 through the core extraction hole 30 of the molded portion 10c of the weather strip.

Then, as shown in FIG. 4, the engaging protrusion 23 of the mounting member 20 is inserted into the engaging hole 103d of the mold forming part 10c of the weather strip, and the locking part 22 is locked to the mold forming part 10c of the weather strip. locking hole 14a. Furthermore, as shown in FIG. 6 , the hook 24 is inserted into the intermediate through-hole 13c of the molded portion 10c in the weather strip and hooked on the peripheral portion of the intermediate through-hole 13c. In addition, the insertion plate portion 25 of the mounting member 20 is inserted into the core extraction hole 30 to close the core extraction hole 30 . This eliminates the need for the work of using an adhesive when sealing the core extraction hole 30 . It should be noted that there is no special restriction on the sequence of these operations.

Next, the weather strip 2 is fixed on the rear door 100 . For fixing, as shown in FIG. 4 , after inserting the engaging protrusion 23 of the mounting member 20 into the engaging hole 103d of the rear door 100 , hook the claw 23a on the peripheral edge of the engaging hole 103d. At this time, because the distance between the upper engaging hole 103d and the lower engaging hole (not shown) is long, the middle part of the molded part 10c of the weather strip may float from the rear door 100, However, in the present embodiment, the mounting member 20 with high rigidity is arranged in the hollow portion 11, whereby the middle part of the mold forming portion 10c of the weather strip can be pressed to the rear door 100 by the mounting member 20, so that The middle portion of the mold forming portion 10 c does not float from the rear door 100 .

In addition, since the middle portion of the molded portion 10c of the weather strip is integrated with the mounting member 20 via the hook 24, positional displacement of the middle portion of the molded portion 10c of the weatherstrip relative to the mounting member 20 can be suppressed, thereby enabling The phenomenon that the molded portion 10c of the weather strip is lifted is suppressed. Furthermore, since the locking portion 22 of the mounting member 20 is locked on the curved wall portion 14 of the molded portion 10c of the weather strip, the hole 30 for extracting the center core can be opened in the state where the weather strip 2 is fixed to the rear door 100 . won't open.

In the manner described above, the weather strip 2 is fixed to the rear door 100 . When the rear door 100 is closed, the hollow portion 11 is sandwiched between the rear door 100 and the vehicle body panel 200 as shown by phantom lines in FIG. and the body panel 200, thereby ensuring sealing. At this time, as the direction of action of the external force is indicated by the arrows, the compressive load acts on the portion of the peripheral wall portion of the hollow portion 11 where the hole 30 for extracting the core is formed, but in the hole 30 for extracting the core Since the insertion plate portion 25 having a thickness substantially equal to the opening width is inserted, the opening width of the core extraction hole 30 hardly changes. Therefore, when setting the shape and size of the hollow portion 11 , it is not necessary to predict changes in the opening width of the core extraction hole 30 .

As described above, according to the weather strip fixing structure 1 according to this embodiment, the hole 30 for extracting the core is formed on the peripheral wall portion of the hollow portion 11 at a portion receiving a compressive load, and is used to fix the center of the weather strip. The insertion plate portion 25 of the mounting member 20 of the mold forming portion 10 c is inserted into the core extraction hole 30 , and the thickness of the insertion plate portion 25 is set to be substantially equal to the opening width of the core extraction hole 30 . Therefore, it is possible to use the mounting member not only for fixing the molded portion 10c of the weather strip but also for closing the hole 30 for extracting the core. Thereby, the conventional work of sealing the core extraction hole 30 with an adhesive is not required, and the shape and size of the hollow portion 11 do not need to be set based on prediction, so that the design can be facilitated.

In addition, since the locking portion 22 of the mounting member 20 is inserted into the locking hole 14a of the curved wall portion 14 of the hollow portion 11 for locking, the mounting member 20 and the curved wall portion 14 can be integrated to effectively suppress the middle The core extraction hole 30 is open.
