Description

Technical Field

[0001] This utility model relates to the field of rubber track molding mold technology, and in particular to a rubber track molding mold. Background Technology

[0002] Rubber tracks are a type of ring-shaped belt structure made of rubber and multi-layered reinforcing materials. They are widely used in agricultural machinery, construction machinery, and other fields. Compared with traditional metal tracks, rubber tracks have the following advantages: high wear resistance: rubber materials are flexible and wear-resistant, adapting to various complex road conditions; and superior shock absorption performance: rubber tracks can absorb vibrations during operation, reduce noise, and improve the comfort and stability of equipment. Because rubber tracks need to meet the requirements of high strength, durability, and dimensional accuracy, their manufacturing process is particularly critical. The molding process of rubber tracks usually includes steps such as raw material processing, mold forming, and vulcanization and curing.

[0003] In existing technologies, such as the Chinese patent CN217802731U "A Segmented Rubber Track Mold", a first mold and a second mold are included. A pin positioning part is set on the first or second mold to fix the pins in a preset position on the mold, ensuring that the distance between the pins at both ends of the segmented rubber track remains constant. Although this technology results in a stable pitch, high tensile strength, and good product quality in the vulcanized track, it still has some drawbacks in practical use. The vulcanization process uses a long strip mold for vulcanization. Because the track is circular, this method can only vulcanize a portion of the track at a time. The remaining portion requires changing the mold or readjusting the placement to complete the vulcanization of the entire track. This operation is not only time-consuming and labor-intensive, significantly increasing production costs, but also prone to defects in track forming due to inaccurate placement during adjustment, thus affecting the overall quality and performance of the track in later use. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a rubber track molding mold to solve the problem that existing track molds cannot integrally mold rubber tracks.

[0005] To achieve the above objectives, this utility model provides a rubber track molding die, including a die assembly for integrally molding a rubber track. The die assembly includes a base plate, an inner core mold, and a side module. The base plate, inner core mold, and side module are all annular in shape. The inner core mold is located on the top of the base plate, and the side module is located on one side of the inner core mold. A blank mold is installed on the corresponding side of the inner core mold and the side module. An extrusion assembly for extruding the blank mold during vulcanization is provided on one side of the side module.

[0006] Preferably, an L-shaped groove is provided on one side of the top of one end of the base plate, and the width of the L-shaped groove is equal to the width of the mold before vulcanization.

[0007] Preferably, the side module has a plurality of first model slots on one side, the inner core mold has a model surface on one side, and the top of the model surface has a second model slot. The dimensions of the side module relative to the inner core mold are adapted to the dimensions of the model surface, and the dimensions of the plurality of first model slots and second model slots are adapted to the dimensions of the track.

[0008] Preferably, a protrusion is fixedly connected to the top of one end of the base plate, and a groove is provided in the middle of the bottom of the inner core mold, the size of which is compatible with the size of the protrusion.

[0009] Preferably, a heating plate is provided on the top of the inner core mold and the side module. When the side module and the inner core mold are placed on the top of the base plate, the heating plate is located at the top of the connection between the side module and the inner core mold. The side module and the inner core mold are made of stainless steel. A second cylinder is installed on the top of the heating plate.

[0010] Preferably, the extrusion assembly includes a pressing block installed on one side of the side module. The pressing block is in the shape of an inverted trapezoid, and the side module is in the shape of a regular trapezoid. A T-shaped fixing block is connected to the inclined side of the pressing block by a plurality of fixing bolts. A slider is fixedly connected to the inclined side of the side module. The side of the slider away from the side module is slidably engaged with the outside of the T-shaped fixing block.

[0011] Preferably, a first wear-resistant block is fixedly connected to the top of one end of the base plate, the first wear-resistant block is located at the bottom of the side module, a second wear-resistant block is fixedly connected to one side of the T-shaped fixing block, and the side of the second wear-resistant block away from the T-shaped fixing block is in contact with one side of the slider.

[0012] Preferably, an air chamber is formed inside one side of the pressing block, and a sliding hole is formed on one side of the pressing block. The output end of the sliding hole is connected to the interior of the air chamber. A limiting post is slidably engaged inside the sliding hole. An air supply pipe is connected to the input end of the limiting post. A hole is formed inside the limiting post. The output end of the air supply pipe is connected to the interior of the air chamber through the hole. A first cylinder is installed on the top of one end of the limiting post. A fixing frame is provided outside the pressing block. The tops of the second cylinder and the tops of the first cylinder are both fixedly connected to one side of the top of the fixing frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. By using a set mold assembly, employing an inner core mold and side modules with a circular structure, and with a reasonable mold layout and extrusion component design, the track can be vulcanized in one piece without the need to replace the mold or readjust the placement. This significantly reduces process steps, improves production efficiency, and lowers labor costs. In use, simply place the entire track between the side modules and the inner core mold, and then use heating plates and extrusion components to promote the integrated vulcanization of the rubber track. This improves work efficiency and saves production costs. Furthermore, by setting the first and second mold slots to precisely match the track specifications and using L-shaped grooves to position the blank mold, the position during vulcanization is ensured to be accurate, avoiding track defects caused by placement deviations and improving the consistency and quality of the finished product.

[0015] During the vulcanization of the track, the pressing block moves the side module downwards with the extrusion assembly. When the bottom of the side module contacts the top of one end of the base plate, the die will be clamped between the side module and the inner core mold. At this time, the first cylinder moves the limiting post downwards, while the pressing block moves downwards continuously. By setting the pressing block to an inverted trapezoid and the side module to a regular trapezoid, as the pressing block moves downwards, one side of the pressing block will continuously squeeze the side module towards the side of the inner core mold. This ensures that the die can be completely matched into the first and second mold grooves during vulcanization, thus achieving a standard track shape and avoiding the problem of inaccurate track forming due to insufficient pressure.

[0026] Such as this utility model Figures 1 to 5 The image shows a rubber track molding die, including a die assembly for integrally molding a rubber track. The die assembly includes a base plate 1, an inner core mold 2, and a side module 5. The base plate 1, the inner core mold 2, and the side module 5 are all annular in shape. The inner core mold 2 is located on the top of the base plate 1, and the side module 5 is located on one side of the inner core mold 2. A blank mold 9 is installed on the corresponding side of the inner core mold 2 and the side module 5. An extrusion assembly for extruding the blank mold 9 during vulcanization is provided on one side of the side module 5.

[0027] By using a set mold assembly, employing an inner core mold 2 and side modules 5 with a circular structure, and with a reasonable mold layout and extrusion component design, the track can be vulcanized in one piece without the need to replace the mold or readjust the placement. This significantly reduces process steps, improves production efficiency, and lowers labor costs. In use, the entire track is simply placed between the side modules 5 and the inner core mold 2. Then, through heating by the heating plate 3 and extrusion by the extrusion component, the rubber track is vulcanized in one piece, which improves work efficiency and saves production costs. At the same time, by setting the first mold groove 6 and the second mold groove 8 to precisely match the track specifications, and by positioning the blank mold 9 through the L-shaped groove 21, the position during the vulcanization process is ensured to be accurate, avoiding track defects caused by placement deviations and improving the consistency and quality of the finished product.

[0028] like Figures 1 to 5 As shown, an L-shaped groove 21 is provided on one side of the top of one end of the base plate 1. The width of the L-shaped groove 21 is equal to the width of the blank mold 9 before vulcanization. Multiple first model grooves 6 are provided on one side of the side module 5. A model surface 7 is provided on one side of the inner core mold 2. A second model groove 8 is provided on the top of the model surface 7. The specifications and dimensions of the side module 5 relative to the inner core mold 2 are adapted to the specifications and dimensions of the model surface 7. The specifications of the multiple first model grooves 6 and the second model groove 8 are adapted to the specifications of the track. A protrusion 11 is fixedly connected to the top of one end of the base plate 1. A groove 10 is provided in the middle of the bottom of the inner core mold 2. The specifications and dimensions of the groove 10 are adapted to the specifications and dimensions of the protrusion 11. A heating plate 3 is provided on the top of the inner core mold 2 and the side module 5. When the side module 5 and the inner core mold 2 are placed on the top of the base plate 1, the heating plate 3 is located at the top of the connection between the side module 5 and the inner core mold 2. The side module 5 and the inner core mold 2 are made of stainless steel. A second cylinder 23 is installed on the top of the heating plate 3.

[0029] Through the configured side module 5 and inner core mold 2, during vulcanization, such as Figure 3 As shown, firstly, the side module 5 and heating plate 3 are lifted away from the top of the base plate 1 using a cylinder. Then, the blank mold 9 is placed on the top of the L-shaped groove 21. At this time, the blank mold 9 will fit against one side of the inner core mold 2, as shown. Figure 4As shown, the first cylinder 22 at the top of the limiting post 13 is activated first, causing the pressing block 4 to move downward with the side module 5. Then, the extrusion assembly is used to clamp the blank mold 9 between the side module 5 and the inner core mold 2. After that, the second cylinder 23 at the top of the heating plate 3 is activated, causing the bottom of the heating plate 3 to contact the top of the side module 5 and the inner core mold 2. Since the side module 5 and the inner core mold 2 are made of stainless steel, the side module 5 and the inner core mold 2 will vulcanize the blank mold 9 through the heating of the heating plate 3, so that the blank mold 9 is completely matched into the first model groove 6 and the second model groove 8, thereby achieving the effect of completing the complete track in one go. This avoids the trouble of traditional track vulcanization multiple times. At the same time, the convex groove 11 and the groove 10 not only stabilize the inner core mold 2, but also facilitate the replacement of the inner core mold 2. This is conducive to making rubber tracks of different shapes to adapt to different vehicle models, thereby expanding the application range of the mold. It is also convenient to lift and remove the inner core mold 2 when removing the rubber track later, thus avoiding the problem of inconvenient track removal.

[0030] like Figures 2 to 5 As shown, the extrusion assembly includes a pressing block 4 installed on one side of the side module 5. The pressing block 4 is in the shape of an inverted trapezoid, and the side module 5 is in the shape of a regular trapezoid. A T-shaped fixing block 19 is threadedly connected to the inclined side of the pressing block 4 through multiple fixing bolts 18. A slider 20 is fixedly connected to the inclined side of the side module 5. The side of the slider 20 away from the side module 5 is slidably engaged with the outside of the T-shaped fixing block 19. A first wear-resistant block 16 is fixedly connected to the top of one end of the base plate 1. The position of the first wear-resistant block 16 is located at the bottom of the side module 5. A second wear-resistant block 17 is fixedly connected to one side of the T-shaped fixing block 19. The side of the second wear-resistant block 17 away from the T-shaped fixing block 19 is in contact with one side of the slider 20.

[0031] During the vulcanization of the track, the pressing block 4 moves the side module 5 downwards along with the extrusion assembly. When the bottom of the side module 5 contacts the top of one end of the base plate 1, the blank mold 9 will be clamped between the side module 5 and the inner core mold 2. At this time, the first cylinder 22 moves the limiting post 13 downwards, while the pressing block 4 moves downwards continuously. By setting the pressing block 4 to be an inverted trapezoid and the side module 5 to be a regular trapezoid, as the pressing block 4 moves downwards, one side of the pressing block 4 will continuously squeeze the side module 5 inwards. The core mold 2 moves to one side, causing the blank mold 9 to fully fit into the first mold groove 6 and the second mold groove 8 during vulcanization, thus achieving a standard track shape and avoiding inaccurate track forming due to insufficient pressure. During use, during vulcanization, the first cylinder 22 moves downwards with the limiting post 13, and simultaneously, the pressing block 4 moves downwards with the limiting post 13. At this point, the bottom of the side module 5 will first contact the top of the base plate 1, and the position of the side module 5 will be aligned with the inner core mold. Corresponding to position 2, the blank mold 9 will be located between the side module 5 and the inner core mold 2. At this time, the first cylinder 22 will continuously push the pressing block 4 downward. Since the shape of the pressing block 4 is an inverted trapezoid and the shape of the side module 5 is also an inverted trapezoid, when the pressing block 4 moves downward, the T-shaped fixing block 19 on one side of the pressing block 4 will slide inside the slider 20, thereby pushing the side module 5 to move continuously towards the side of the inner core mold 2. At the same time, when the side module 5 moves, it will continuously squeeze the blank mold 9, thereby causing the blank mold 9 to be completely clamped between the side module 5 and the inner core mold 2. This achieves stable vulcanization of the blank mold 9, and also promotes the vulcanization of the blank mold 9. Through the continuous squeezing action of the side module 5, the blank mold 9 is completely vulcanized into the interior of the first mold groove 6 and the second mold groove 8, thereby achieving the function of integrally molded rubber track. At the same time, the first wear-resistant block 16 and the second wear-resistant block 17 can protect the high friction parts, thereby extending the service life of the mold and reducing the maintenance costs caused by mold wear.

[0032] like Figure 2 and Figure 4 As shown, an air chamber 12 is provided inside one side of the pressing block 4, and a sliding hole 15 is provided on one side of the pressing block 4. The output end of the sliding hole 15 is connected to the inside of the air chamber 12. A limiting post 13 is slidably engaged inside the sliding hole 15. An air supply pipe 14 is connected to the input end of the limiting post 13. A hole is provided inside the limiting post 13. The output end of the air supply pipe 14 is connected to the inside of the air chamber 12 through the hole. A first cylinder 22 is installed on the top of one end of the limiting post 13. A fixing frame 24 is provided outside the pressing block 4. The top of the second cylinder 23 and the top of the first cylinder 22 are both fixedly connected to one side of the top of the fixing frame 24.

[0033] By using the air chamber 12 and the limiting post 13, precise adjustment of the extrusion pressure can be achieved, avoiding damage to the mold 9 due to excessive or uneven pressure, while improving operational safety and reliability. When the side module 5 completely clamps the mold 9 between the side module 5 and the inner core mold 2, an air pump is connected to the input end of the air supply pipe 14. When the air pump supplies air to the air supply pipe 14, the air supply pipe 14 will supply air to the inside of the air chamber 12. When the inside of the air chamber 12 is full of gas, more gas will continue to enter, and the sliding hole 15 will then... The limiting post 13 slides outside, thereby expanding the internal space of the air chamber 12 to store gas. When the sliding hole 15 slides outside the limiting post 13, the pressing block 4 will move, causing the pressing block 4 to push the side module 5 to move to one side of the inner core mold 2 again, thereby ensuring that the mold 9 can obtain sufficient pressure during vulcanization. At the same time, when the pressure is too high, the gas inside the air chamber 12 is sucked out by the air pump, causing the side module 5 to reduce the pressure on the mold 9, thereby achieving the effect of regulating pressure and avoiding damage to the mold 9 due to excessive or uneven pressure.
