technical field

The present application relates to the field of horizontal injection molding machines, in particular to a bending-resistant track of a horizontal injection molding machine.

Background technique

Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is mainly divided into vertical type and horizontal type. With the gradual improvement of injection molding machine technology and mold technology, the injection molding machine The production field is further developing towards high precision and high production capacity. Compared with vertical injection molding machines, horizontal injection molding machines can often design larger clamping parts, so they can also provide higher production capacity. Therefore, in terms of market share Horizontal injection molding machines far exceed vertical injection molding machines.

However, limited by the structure of the horizontal injection molding machine, in the face of high-precision products and molds, the problems of broken tie rods and templates often occur, which greatly affects the development of horizontal injection molding machines. It is a technology in this field. problems that people need to solve.

Contents of the invention

An object of the present application is to provide a bending-resistant track of a horizontal injection molding machine to solve the problems of broken tie rods and broken templates that often occur when facing high-precision products and molds.

In order to achieve the above object, the technical scheme adopted in this application is:

A bending-resistant track of a horizontal injection molding machine, installed on the frame of the horizontal injection molding machine, the bending-resistant track is suitable for carrying the clamping parts or injection parts of the horizontal injection molding machine, the bending-resistant The track includes a track assembly, which is arranged on the frame along the left-right direction, and the top of the track assembly is provided with a plurality of deformation grooves at intervals along the front-to-back direction, and a lubricating block is arranged in the deformation groove. The block is made of elastic material, and the clamping part or the injection part is suitable for resisting the track assembly, the deformation groove and the top of the lubricating block. The groove wall of the deformation groove is adapted to deform inwardly or outwardly, so as to force the deformation of the lubricating block and control the deformation amount of the top of the track assembly.

Existing horizontal injection molding machines generally need to provide higher clamping pressure to meet the production of high-precision products when facing high-precision product production, and at the same time cooperate with high-speed injection parts to improve production efficiency and Improve the smoothness of the product surface and improve product quality. However, due to the cost limitation of the horizontal injection molding machine, the overall frame is usually welded and formed by steel, and the plane of the guide rail where the clamping parts and injection parts are installed is milled by a milling machine to meet the level of the installation plane of the clamping parts and injection parts, but In actual use, most of the ground planes where injection molding machines are placed are usually conventional grounds, rather than specially hardened and leveled foundations. Therefore, the ground planes where injection molding machines are placed usually have a certain height difference. Formed by welding steel, its rigidity is poor, it is difficult to level the guide rail in the actual use process, even if the leveling operation is carried out, due to the poor rigidity of the rack itself, the guide rail plane will still appear in the actual use process A certain bend. Therefore, during operation, the guide rail usually bends to a certain extent with the height difference of the rack installation ground, which causes the plane of the guide rail to bend, and causes the clamping parts and injection parts to change with the plane of the guide rail during the movement process. Its displacement in the up and down direction, and because the clamping part and the injection part are casted by castings, their weight is relatively large, and the displacement in the up and down direction will act on the pull rod and the shooting guide rod of the injection molding machine, resulting in the pulling rod and shooting guide rod of the injection molding machine The fracture of the guide rod, and because of its uneven force, it is more likely to cause problems such as fracture of the template during use. In addition, it is worth mentioning that because the length of the horizontal injection molding machine is long and the width is generally not large, when the ground is uneven in the left and right directions, it is more likely to have a height difference that affects the plane of the guide rail, resulting in high-speed, high-pressure injection molding machines.

Existing horizontal injection molding machines generally need to provide higher clamping pressure to meet the production of high-precision products when facing high-precision product production, and at the same time cooperate with high-speed injection parts to improve production efficiency and Improve the smoothness of the product surface and improve product quality. However, due to the cost limitation of the horizontal injection molding machine, the overall frame is usually welded and formed by steel, and the plane of the guide rail where the clamping parts and injection parts are installed is milled by a milling machine to meet the level of the installation plane of the clamping parts and injection parts, but In actual use, most of the ground planes where injection molding machines are placed are usually conventional grounds, rather than specially hardened and leveled foundations. Therefore, the ground planes where injection molding machines are placed usually have a certain height difference. Formed by welding steel, its rigidity is poor, it is difficult to level the guide rail in the actual use process, even if the leveling operation is carried out, due to the poor rigidity of the rack itself, the guide rail plane will still appear in the actual use process A certain bend. Therefore, during operation, the guide rail usually bends to a certain extent with the height difference of the rack installation ground, which causes the plane of the guide rail to bend, and causes the clamping parts and injection parts to change with the plane of the guide rail during the movement process. Its displacement in the up and down direction, and because the clamping part and the injection part are casted by castings, their weight is relatively large, and the displacement in the up and down direction will act on the pull rod and the shooting guide rod of the injection molding machine, resulting in the pulling rod and shooting guide rod of the injection molding machine The fracture of the guide rod, and because of its uneven force, it is more likely to cause problems such as fracture of the template during use. In addition, it is worth mentioning that because the length of the horizontal injection molding machine is long and the width is generally not large, when the ground is uneven in the left and right directions, it is more likely to have a height difference that affects the plane of the guide rail, resulting in high-speed, high-pressure injection molding machines. Under the working conditions of the injection molding machine, the tie rod of the injection molding machine is prone to breakage.

Therefore, the inventor found that it is necessary to develop a bending-resistant track that can adaptively adjust the plane of the guide rail according to the site of use, which can be used under poor working conditions, and ensure that the pull rods and templates of the injection molding machine are used at high speed and high pressure. There will be problems of cracking and breaking.

Accordingly, the inventors of the present application have developed a bending-resistant track for a horizontal injection molding machine, as shown in Figures 1 to 16, installed on the frame 100 of the horizontal injection molding machine, and the bending-resistant track is suitable for carrying horizontal The clamping part or injection part of the injection molding machine, the anti-bending track includes a track assembly 1, and the track assembly 1 is arranged on the frame 100 along the left and right directions. 11 is provided with a lubricating block 12, the lubricating block 12 is made of elastic material, the clamping part or the injection part is suitable for resisting the top of the rail assembly 1, the deformation groove 11 and the lubricating block 12, when the frame 100 appears bending deformation in the up and down direction , the groove wall of the deformation groove 11 is adapted to deform inwardly or outwardly, thereby forcing the deformation of the lubricating block 12 and controlling the deformation amount of the top of the track assembly 1 .

The anti-bending track used in this application has a plurality of deformation grooves 11 arranged at intervals along the front and rear directions on the top of the track assembly 1. When the frame 100 on which the track assembly 1 is installed is deformed, it will also cause the track assembly 1 to deform. Since the rail assembly 1 is provided with a deformation groove 11, the degree of deformation of the upper surface of the rail assembly 1 can be reduced, thereby reducing the flatness of the plane on which the mold clamping parts or injection parts are installed and the straightness change along the left and right directions, thereby playing a role anti-bending effect. As shown in Figures 5 and 6, if the frame 100 is in a completely horizontal position, then the top of the track assembly 1 fixedly installed with the frame 100 is also in a completely horizontal state, and at this moment, no matter the clamping part or the injection part is in the How to move on the track assembly 1, the tension of each tie rod, template and injection guide rod of the injection molding machine is uniform, and it is not easy to break, deform and other problems, which is convenient for the production of high-precision products, and is suitable for high-speed and high-pressure environments. . It is worth mentioning that high-precision products usually need to be produced under high injection speed and high clamping pressure. Therefore, in the high-speed and high-pressure production environment, new requirements are put forward for the durability and reliability of horizontal injection molding machines.

However, in the actual use environment of the horizontal injection molding machine, due to the limitation of its production environment, and because the length of the horizontal injection molding machine far exceeds the width, the height difference in the length direction (ie, the left and right directions) is likely to cause the frame 100 to appear. bend, and force the rail assembly 1 installed on the frame 100 to deform, if a conventional rail assembly 1 is adopted, then the top of the rail assembly 1 will also undergo a deformation similar to that of the foundation plane, because the length direction is longer, this The change of the height difference will greatly change the straightness of the track, resulting in uneven force on the clamping parts or injection parts during operation, resulting in a decline in the quality of the injection molding machine, and some parts are easily damaged. Fig. 6 shows that the track assembly 1 is placed on a foundation with a certain height difference.

As shown in Figures 7a and 7b, since the deformation groove 11 is set on the track assembly 1, when a higher height occurs, the material near the groove wall on both sides of the deformation groove 11 expands outward (as shown in the direction of the arrow in Figure 7a As shown), the deformation groove 11 is deformed to form a situation as shown in Figure 7b.

As shown in Fig. 8a and Fig. 8b, because the deformation groove 11 is set on the track assembly 1, when there is a lower height, the material near the groove walls on both sides of the deformation groove 11 shrinks in the deformation groove 11 (as shown in Fig. 8a arrow direction), so that the deformation groove 11 appears inward deformation, forming the situation as shown in Figure 8b.

Although the deformation groove 11 can not completely resist the straightness change caused by the height difference of the frame 100 in the left-right direction, it will offset most of the deformation, thereby making the deformation degree of the top of the track assembly 1 smaller, thereby realizing the track The anti-bending effect of the component 1 achieves the purpose of improving the durability of the track component 1, injection parts, mold clamping parts, and tie rods.

In addition, a lubricating block 12 made of elastic material is installed in the deformation groove 11, which can improve the rigidity of the overall track assembly, so that the track assembly 1 has better rigidity when facing a high weight load, and reduces the damage caused by excessive load. deformation, thereby improving the use effect. In addition, the lubricating block 12 can be made of graphite material soaked by lubricating oil. During use, affected by the effect of the groove wall and heavy load, the lubricating block 12 made of graphite material can leach lubricating oil, further improving Smooth running of clamped or injected parts, reducing wear due to dry friction.

As a preference, as shown in Figure 4 and Figure 9, the bottom of the track assembly 1 is provided with an oil storage tank 13 along the left and right direction, the notch of the oil storage tank 13 is arranged downward relative to the top of the frame 100, the inner wall of the oil storage tank 13 and The top of the frame 100 jointly defines an oil storage chamber 2, which is suitable for storing lubricating oil in the oil storage chamber 2; the groove bottom of the deformation groove 11 is provided with a penetration through hole 111, and the penetration through hole 111 is suitable for communicating with the oil storage chamber 2 and the deformation groove 11, the lubricating block 12 is installed in the deformation groove 11, and the bottom of the lubricating block 12 is suitable for sealing the penetration through hole 111, the lubricating block 12 is provided with a plurality of lubricating through holes 121 along the vertical direction, and the lubricating through hole 121 communicates with the storage When the oil chamber 2 is subjected to bearing force, the lubricating oil in the oil storage chamber 2 is suitable to flow out from the lubricating through hole 121 and lubricate the upper surface of the lubricating block 12 .

In this specific embodiment, lubricating oil uses No. 00 lubricating oil, which has a certain viscosity and a certain fluidity, which is convenient for use and replacement. The lubricating block 12 is made of graphite, and is soaked before installation, and through the lubricating through hole 121 provided on the lubricating block 12, the lubricating oil in the oil storage chamber 2 can be squeezed when the lubricating block 12 is squeezed (including being The extrusion of the groove wall of the deformation groove 11 and due to the gravity of the clamping part or the injection part) will flow out from the lubricating through hole 121, reducing the occurrence of dry friction, and can form a layer of oil film, which can reduce to a certain extent due to The poor flatness of the foundation causes the problem of poor flatness at the top of the track assembly 1 . In addition, in this specific embodiment, the track assembly 1 can be fixedly connected to the surface of the frame 100 by welding, so as to improve the sealing of the oil storage chamber 2 .

Setting the oil storage chamber 2 and the oil storage tank 13 can further reduce the poor flatness of the top of the track assembly 1 caused by the poor flatness of the ground at the installation position of the frame 100, thereby affecting the service life of the injection molding machine pull rods and templates. The lubricating oil in the oil storage chamber 2 can flow out from the lubricating through hole 121, thereby forming a layer of oil film between the track assembly 1 and the clamping parts or injection parts, and this layer of oil film can further reduce the friction between the track assembly 1 and the clamping parts or injection parts. The gap between the injection parts can further reduce the influence of the deformation of the top of the track assembly 1, and further improve the bending resistance of the guide rail of the injection molding machine. It is worth mentioning that the bending resistance refers to the ability of the track assembly 1 to prevent the top of the injection molding machine from bending deformation when the ground is uneven and the height difference between the left and right directions is large. In addition, setting the penetration through hole 111 can increase the contact area between the lubricating block 12 and the lubricating oil in the oil storage chamber 2, so that the lubricating block 12 is immersed in more lubricating oil during use, so that its surface is always lubricated. state.

As a preference, as shown in Figure 10, the anti-bending track also includes a sealing assembly 3, the sealing assembly 3 is installed in the oil storage tank 13, and the bottom of the sealing assembly 3 is fixedly connected to the top of the frame 100, and the top of the sealing assembly 3 , the inner wall of the oil storage tank 13 jointly define the oil storage chamber 2 , and the sealing assembly 3 is suitable for controlling the sealing performance of the oil storage tank 13 .

Using the seal assembly 3 can facilitate the cleaning and maintenance of the inside of the track assembly 1. Since the bottom of the seal assembly 3 is fixedly connected to the bottom of the frame 100, when it is necessary to replace the track assembly 1 or clean the oil storage chamber 2, the track assembly 1 can be Separated from the sealing assembly 3, even if the oil storage tank 13 is separated from the sealing assembly 3, it is convenient to replace the track assembly 1, and simplifies the operation steps for later maintenance.

As a preference, as shown in Figure 10, the side wall of the sealing assembly 3 is provided with sealing ring installation grooves 31 along the circumferential direction, the number of sealing ring installation grooves 31 is not less than two, and the sealing ring installation grooves 31 are suitable for Install the sealing ring and control the tightness between the sealing assembly 3 and the oil storage tank 13 . It is worth mentioning that the sealing ring used is not a standard sealing ring, but a large sealing ring formed by thermal bonding technology, thereby increasing the sealing performance of the oil storage chamber 2 .

During use, a certain pressure can be provided to the lubricating oil in the oil storage chamber 2, so that the lubricating oil in the oil storage chamber 2 can move upward along the lubricating through hole 121, and the best state is to make the lubricating oil in the lubricating through hole 121 The height of the lubricating oil liquid level in the lubricating oil is equal to the height of the top of the lubricating through hole 121. At this time, when the load passes through, the lubricating oil in the lubricating through hole 121 will flow out when the load passes by, and the lubricating block 12 will return to deformation when the load disappears. , thereby reducing the waste of lubricating oil and reducing environmental pollution.

The sealing ring installation groove 31 and the sealing ring are provided to increase the sealing performance of the oil storage chamber 2, thereby ensuring that lubricating oil under a certain pressure will not flow out of the oil storage chamber 2.

As a preference, as shown in Figures 11 to 16, the anti-bending track also includes an adjustment assembly 4, the adjustment assembly 4 is installed in the oil storage tank 13, and the top of the adjustment assembly 4 is against the top wall of the oil storage tank 13, and the adjustment assembly 4 The bottom is in contact with the top of the sealing assembly 3, and the top of the adjustment assembly 4 is provided with a plurality of first oil grooves 41 at intervals along the front-to-back direction. The projection positions of the deformation grooves 11 on the horizontal plane are the same, and the first oil groove 41 is suitable for storing lubricating oil.

Since the bottom of the track assembly 1 is provided with an oil storage tank 13, which is provided with lubricating oil, in the case of high load, the strength of the track assembly 1 may be insufficient, resulting in fracture, so the adjustment assembly 4 is added to improve the track assembly 1. The overall strength makes the top of the adjustment assembly 4 collide with the top wall of the oil storage tank 13, and the bottom of the adjustment assembly 4 collides with the top of the sealing assembly 3, so that the adjustment assembly 4 can withstand the high load of the track assembly 1, and the front and rear direction is set. The first oil groove 41 can further alleviate the change in flatness of the top of the track assembly 1 caused by the height difference of the ground in the front-back direction. When there is a height difference in the front-to-back direction, since the first oil tank 41 is also arranged along the front-to-back direction, and lubricating oil is stored therein, due to the appearance of the height difference, the first oil tank 41 will also change along the front-to-back direction, so that the oil also A certain degree of change occurs, and then the thickness of the oil layer between the adjustment assembly 4 and the track assembly 1 changes, thereby further alleviating the flatness change at the top of the track assembly 1 caused by the height difference of the ground in the front and rear directions.
