Mold

The present invention relates to a mold, and more particularly to a mold for a two-stage mold opening.

In today's industrial environment, the application of molds has become quite common and has been widely used in various precision products. However, due to its complex structure and high precision requirements for finished products, precision products make the corresponding mold structure more complicated.

Generally, when the mold is opened, the inclined guide column is often arranged between the male mold, the slider and the female mold, and the force is perpendicular to the mold opening direction by the inclined guide column, and the slider is moved to make the male mold and the male mold The mother molds are separated from each other. However, there is a problem in this way. When the mold is released, the slider may be slightly moved under the traction of the inclined guide column or the external force, causing unpredictable damage (in which the vertical is off and off) The male model and the female mold of the mold are more serious.

The conventional solution is nothing more than: in order to avoid unpredictable micro-movement, the inner diameter of the guide hole of the slider is increased, so that the oblique guide column and the slider have a buffer space (in other words, the oblique guide column starts to move to Push the slider to have a time difference) to avoid accidental movement of the slider. Alternatively, use the positioning bead snap slider to ensure that the slider does not move freely.

However, the above two solutions have their own drawbacks. The former adopts the method of setting the buffer space, and it is incapable of accurately controlling the demolding condition. The user will not know how much displacement the oblique guide column needs to move the slider; and the latter positioning The bead has problems such that the inner spring of the positioning bead does not necessarily bounce back, the slider cannot be reliably buckled, or the inner spring falls off, so that the unpredictable micro-movement problem cannot be solved.

Therefore, how to provide a mold at the moment when the mold is opened and the slider does not move, so as to achieve accurate positioning and solve the problem of micro-movement when the slider is not moved when the mold is opened has become an important subject in the field.

In view of the above problems, an object of the present invention is to provide a precisely positionable Mold.

Another object of the present invention is to solve the problem of micro-movement when the slider is not moved when the mold is opened.

In order to achieve the above object, the present invention provides a mold which is disposed on a substrate. The mold of the present invention includes a male mold, a female mold, a slider, a diagonal guide, and a shutter. The mother mold and the male mold are set together. The slider is disposed between the male mold and the female mold, the male mold, the female mold and the slider are adjacent to each other, and the slider is provided with a guiding hole and a clamping hole. One end of the inclined guiding rod is coupled to the female mold core, and the other end is disposed on the guiding hole. One end of the shutter is coupled to the male mold core, and the other end is disposed at the clamping hole.

Wherein, in the first mold opening stage, the oblique guide rod moves along the guide hole to provide a thrust of the female mold core, so that the male mold core is separated from the female mold core. In the second mold opening stage, the inclined guide rod continues to move along the guide hole to provide a thrust of the slider to overcome the friction between the shutter and the clamp hole, and the slider moves relative to the male mold, the male mold and the slippery Block separation.

In an embodiment, the mold of the present invention further includes a limiting unit disposed on the substrate and located in a moving path of the slider.

In an embodiment, the limiting unit includes a positioning member disposed on a positioning slot of the substrate. Wherein, the positioning member is a positioning bead or a positioning button.

In an embodiment, the slider further includes a snap groove. During the second mold opening stage, when the positioning member is snapped into the buckle groove, the slider stops moving.

In an embodiment, the limiting unit further includes a blocking member that stops moving when the slider contacts the blocking member during the second mold opening phase.

In an embodiment, the shutter is a resin shutter.

In an embodiment, the inner diameter of the pilot hole is larger than the diameter of the diagonal guide. Wherein, the inner diameter of the guiding hole is larger than the diameter of the oblique guiding rod by 4 mm.

In an embodiment, the pilot hole is inclined through the slider.

As described above, the mold of the present invention can prevent the slider from moving at the moment of mold opening, and can achieve precise positioning and solve the problem of micro-movement when the slider is not moved when the mold is opened.

Figure 3 is a schematic view of the mold of the present invention in a second mold opening stage.

In the following, a mold according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein the same elements will be described with the same reference numerals, and the elements that are not directly related to the present invention will be omitted.

Please refer to FIG. 1 to FIG. 3 together, which are respectively schematic diagrams of the mold 1 which has not been opened, the first mold opening stage and the second mold opening stage.

Referring to FIG. 1 , the mold 1 of the two-stage mold opening of the present invention is in an unopened (closed) state, and the mold 1 is disposed on a substrate 2 . The mold 1 of the present invention includes a male mold core 11, a female mold core 12, a slider 13, a skew guide 14, and a shutter 15. Among them, the mother mold 12 can be set with the male mold 11 and the female mold 12 can be combined with the male mold 11 to mold or demould, in other words, when the mold 1 has not been demolded, the male mold 11 and the female mold core 12 and the slider 13 are disposed adjacent to each other.

The slider 13 is disposed between the male mold 11 and the female mold core 12, and the slider 13 is provided with a guiding hole 132 and a clamping hole 134. One end of the inclined guiding rod 14 is coupled to the female mold core 12 , and the other end is disposed on the guiding hole 132 . In addition, the present invention may further include an embodiment of the guide hole 132 extending obliquely through the slider 13.

The shape and the inclination angle of the guiding hole 132 are preferably matched with the appearance of the inclined guiding rod 14. For example, when the inclined guiding rod 14 of the embodiment is a cylindrical body, the guiding hole 132 is a cylindrical perforation.

In the state of FIG. 1, the inclined guide 14 is disposed (partially absent) in the guide hole 132. Moreover, the diameter L ₁ of the inclined guiding rod 14 of the embodiment is about 20 mm, and the inner diameter L _{2 of the} guiding hole 132 can be slightly larger than the diameter L ₁ of the inclined guiding rod 14 by about 4 mm. In addition, one end of the shutter 15 is coupled to the male mold 11 , and the other end of the shutter 15 is disposed at the clamping hole 134 . The outer diameter of the other end of the shutter 15 is slightly larger than the diameter of the clip hole 134, so that the shutter 15 is clamped in the clip hole 134, so that the frictional force continues between the shutter 15 and the clip hole 134.

The shutter 15 may be a resin shutter, and one end of the shutter 15 is coupled and fixed to the male mold 11 by a fixing member (not shown), and the other end of the shutter 15 is disposed at the clamping hole 134. The material is made of resin. In short, when the slider 13 is turned to the first mold opening stage in the unopened state, the shutter 15 and the clip hole 134 are rested on the substrate 2 without moving relative to the male mold 11 .

The mold 1 of the present invention may further include a limiting unit 16 disposed on the substrate 2 And in a moving path of the slider 13, the purpose is to stop the slider 13 after moving to the required distance. Moreover, the slider 13 of the present invention may further include a locking groove 136, and the locking groove 136 may cooperate with the limiting unit 16 to control the movement of the slider 13.

The positioning unit 16 of the embodiment includes a positioning member 161. The positioning member 161 is disposed on the positioning groove 1612 of the substrate 2, and the positioning member 161 can be engaged with the locking groove 136 of the slider 13. The position limiting unit 16 of the present embodiment further includes a blocking member 162. The figure exemplifies that the positioning member 161 is a positioning bead, but the positioning member of the embodiment may be a positioning button, which is not limited to the embodiment.

It should be noted that the limiting unit 16 of FIG. 1 is not in common with the shutter 15 , and FIG. 1 is only for convenience of illustration. The limiting unit 16 and the shutter 15 are drawn in the same cross section, but the actual configuration should not be This is limited.

Referring to FIG. 2 in particular, in the first mold opening stage, an external force is provided to move the inclined guide 14 upward along the guide hole 132 (at this time, the oblique guide 14 is separated from the inner surface of the guide hole 132, in other words, the first opening At the beginning and end of the mold phase, the inclined guide 14 is not in contact with the inner surface of the guide hole 132, and the thrust of the female mold 12 is provided, so that the male mold 11 is separated from the female mold 12 (sliding at this time) The block 13 does not move until the side of the inclined guide 14 is pressed against the inner surface of the guide hole 132 to stop moving.

It should be specially noted that at this stage, when the oblique guide 14 moves, the slider 13 is static on the substrate 2 through the friction between the shutter 15 and the clip hole 134. Therefore, when the external force provided in the first mold opening stage is less than the frictional force, the slider 13 will not be displaced.

Next, please refer to Figure 3, in the second mold opening stage, provide another external force (need to Less than the friction between the shutter 15 and the clip hole 134), the ramp guide 14 continues to move along the guide hole 132 and provides a thrust of the slider 13.

When the aforementioned thrust overcomes the friction between the shutter 15 and the clip hole 134, the slip Block 13 begins to move, causing slider 13 to move relative to male mold 11 . In other words, at this time, the inclined guide 14 provides the thrust of the slider 13 to the left, so that the slider 13 starts to move to the left until the slider 13 contacts the resistance. When the blocking member 162 and the positioning member 161 are engaged with the locking groove 136, the slider 13 stops moving. At this time, the male mold 11 is separated from the slider 13.

In summary, the mold of the present invention only uses the female mold core during the first mold opening stage. Pulling away from the male mold, and not moving/pushing the slider, when the female mold is separated by a distance, the inclined guide extends the guide hole and pushes the slider to separate the slider from the male mold (second mold opening stage) . In addition, the frictional force of the shutter and the clamping hole of the slider is utilized, and in the first mold opening stage, the slider is temporarily rested. Therefore, with the above configuration, the present invention can achieve the problem that the slider does not move, accurately locate, and solve the micro movement when the slider is not moved when the mold is opened.

The above is intended to be illustrative only and not limiting. Any departure from this issue The spirit and scope of the Ming Dynasty, and equivalent modifications or changes to it, shall be included in the scope of the patent application attached.
