Description

Technical Field

[0001] This utility model belongs to the field of automotive rubber product manufacturing technology, specifically relating to an extrusion molding die for automotive rubber products. Background Technology

[0002] Rubber products play a crucial role in automobile manufacturing. They not only provide functions such as sealing, dustproofing, shock absorption, and sound insulation, but also directly affect the driving safety and performance of automobiles.

[0003] Chinese utility model patent CN220534730U discloses a molding die for a rubber shock-absorbing pad, including a base. A lower die is fixedly installed on the top of the base. The lower die has a bottom cooling pipe and a side cooling pipe arranged inside a groove, with one end of the bottom cooling pipe and one end of the side cooling pipe connected. A cooling pipe is fixedly installed inside the base in a slot, and a connecting pipe connects the other end of the cooling pipe and the other end of the side cooling pipe. Cooling water flows along the bottom cooling pipe and the side cooling pipe, carrying away the heat of the rubber shock-absorbing pad workpiece inside the mold, thereby cooling the workpiece. The cooling water is transferred to the cooling pipe through the connecting pipe. Since the cooling pipe is coiled back and forth, the cooling water flows and cools within the coiled cooling pipe. At the same time, cooling fans on both sides blow air onto the cooling pipe, thereby achieving the effect of cooling and cutting the workpiece in a back-and-forth cycle, improving the processing and production speed of the product.

[0004] However, although the above-mentioned molding mold can cool and shape rubber products and improve the processing speed, it does not have the function of disassembling the upper mold. If the internal parts of the upper mold are damaged but cannot be disassembled separately, it will affect the use of the entire device and make it inconvenient for users. Utility Model Content

[0005] This invention provides an extrusion mold for automotive rubber products to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An extrusion molding die for automotive rubber products includes a base, a lower die fixedly mounted on the top of the base, side plates fixedly mounted on both sides of the lower die, a limit rod fixedly mounted on the top of the side plate, a top plate fixedly mounted on the top of the limit rod, an electric telescopic rod fixedly mounted on the top of the top plate, the telescopic end of the electric telescopic rod penetrating the top plate and fixedly connected to the top of a lifting plate, a bidirectional threaded rod movably mounted inside the lifting plate, a nut seat movably mounted outside the bidirectional threaded rod, a snap-fit ​​plate fixedly mounted at the bottom of the nut seat, and the snap-fit ​​plate snapping into snap-fit ​​grooves opened on both sides of the top of the upper die.

[0008] As a preferred embodiment, a cooling pipe is fixedly provided inside the lower mold, and one end of the cooling pipe penetrates the front surface of the lower mold and extends to the outside of the lower mold, while the other end of the cooling pipe penetrates the front surface of the base and extends to the outside of the base.

[0009] As a preferred embodiment, cooling fans are fixedly installed on both sides of the interior of the lower mold.

[0010] As a preferred embodiment, a spring is sleeved on the outside of the limiting rod, and a collar is located above the spring and sleeved on the outside of the limiting rod.

[0011] As a preferred embodiment, sliding sleeves are fixedly provided on both sides of the lifting plate, and a sleeve is fixedly provided at the bottom of the sliding sleeve, and both the sliding sleeve and the sleeve are sleeved on the outside of the limiting rod.

[0012] As a preferred embodiment, a first bevel gear is fixedly provided on the outside of one end of the bidirectional threaded rod, a second bevel gear is movably provided on one side of the first bevel gear, a rotating handle is fixedly provided inside the second bevel gear, and the first bevel gear meshes with the second bevel gear.

[0013] As a preferred embodiment, the bidirectional threaded rod is threadedly connected to the nut seat, and the nut seat has a threaded hole inside that is adapted to the bidirectional threaded rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention features a bidirectional threaded rod, a nut seat, and a snap-fit ​​plate. By rotating the rotating handle, a second bevel gear is driven to rotate, which in turn drives a first bevel gear to rotate. This, in turn, drives the bidirectional threaded rod to rotate. Since the threads at both ends of the bidirectional threaded rod are in opposite directions, the nut seat can cause the snap-fit ​​plate to move horizontally in the opposite direction. This releases the snap-fit ​​plate from the snap-fit ​​grooves on both sides of the top of the upper mold, allowing for the disassembly of the upper mold. This facilitates the maintenance or replacement of the upper mold and ensures the production efficiency of automotive rubber products. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 As shown, this embodiment of the utility model provides an extrusion molding die for automotive rubber products, specifically including a base 1. A lower die 2 is fixedly mounted on the top of the base 1. Side plates 3 are fixedly mounted on both sides of the lower die 2. A limit rod 301 is fixedly mounted on the top of the side plate 3. A top plate 4 is fixedly mounted on the top of the limit rod 301. An electric telescopic rod 401 is fixedly mounted on the top of the top plate 4. The telescopic end of the electric telescopic rod 401 passes through the top plate 4 and is fixedly connected to the top of a lifting plate 5. A bidirectional threaded rod 501 is movably mounted inside the lifting plate 5. A nut seat 505 is movably mounted outside the bidirectional threaded rod 501. A snap-fit ​​plate 506 is fixedly mounted at the bottom of the nut seat 505. The snap-fit ​​plate 506 snaps into the snap-fit ​​grooves opened on both sides of the top of the upper die 507.

[0022] Specifically, in this embodiment, during use, the user first activates the electric telescopic rod 401, causing its telescopic end to drive the lifting plate 5 to move vertically up and down. Simultaneously, the sleeve 509 presses downwards against the collar 303, compressing the spring 302. This provides cushioning during mold closing, preventing excessive pressure from damaging the lower mold 2. Coolant is then supplied to the cooling pipe 201, cooling the automotive rubber product from the bottom and sides of the mold cavity, achieving cooling and shaping. The heat-absorbing coolant then flows out from the other end of the cooling pipe 201, enabling circulating cooling. The cooling fan 202 further cools the coolant inside the cooling pipe 201, improving the cooling effect on the automotive rubber product. Regarding the cooling efficiency of the product, when the internal parts of the upper mold 507 are damaged, rotating the rotating handle 504 drives the second bevel gear 503 to rotate, which in turn drives the first bevel gear 502 to rotate. This, in turn, drives the bidirectional threaded rod 501 to rotate. Since the threads at both ends of the bidirectional threaded rod 501 are in opposite directions, the nut seat 505 can drive the snap-fit ​​plate 506 to move horizontally in the opposite direction. This releases the snap-fit ​​plate 506 from the snap-fit ​​grooves on both sides of the top of the upper mold 507, allowing the upper mold 507 to be disassembled. This facilitates the repair or replacement of the upper mold 507 and extends the service life of the device.

[0023] Please see Figure 1 and Figure 2 As shown, a cooling pipe 201 is fixedly installed inside the lower mold 2. One end of the cooling pipe 201 penetrates the front surface of the lower mold 2 and extends to the outside of the lower mold 2, while the other end penetrates the front surface of the base 1 and extends to the outside of the base 1. By installing the cooling pipe 201, coolant is transferred into the cooling pipe 201, and the coolant cools the automotive rubber product from the bottom and sides of the mold cavity, achieving cooling and shaping of the automotive rubber product. The coolant that has absorbed heat then flows out from the other end of the cooling pipe 201, achieving circulating cooling, which is highly practical and easy for users to use. Cooling fans 202 are fixedly installed on both sides inside the lower mold 2. By installing the cooling fans 202, the coolant inside the cooling pipe 201 can be cooled, further improving the cooling efficiency of the automotive rubber product, which is also highly practical.

[0024] Please see Figure 2 and Figure 3As shown, a spring 302 is sleeved on the outside of the limiting rod 301. Above the spring 302 and sleeved on the outside of the limiting rod 301, a collar 303 is provided. Sliding sleeves 508 are fixedly provided on both sides of the lifting plate 5. A sleeve 509 is fixedly provided at the bottom of the sliding sleeve 508, and both the sliding sleeve 508 and the sleeve 509 are sleeved on the outside of the limiting rod 301. When the lifting plate 5 drives the upper mold 507 to move downward, the sleeve 509 will press down on the collar 303, causing the spring 302 to compress. This will buffer the lower mold 2 during mold closing, preventing excessive pressure from damaging it and extending its service life. This design is highly practical and easy for users to use.

[0025] Please see Figure 2 and Figure 3 As shown, a first bevel gear 502 is fixedly mounted on the outside of one end of the bidirectional threaded rod 501. A second bevel gear 503 is movably mounted on one side of the first bevel gear 502. A rotating handle 504 is fixedly mounted inside the second bevel gear 503, and the first bevel gear 502 and the second bevel gear 503 mesh with each other. By setting the first bevel gear 502 and the second bevel gear 503, and utilizing the meshing connection between the first bevel gear 502 and the second bevel gear 503, rotating the rotating handle 504 drives the second bevel gear 503 to rotate, which in turn drives the first bevel gear 502 to rotate, thereby causing the first bevel gear 502 to drive the bidirectional threaded rod 501 to rotate, thus achieving the purpose of driving the bidirectional threaded rod 501 to rotate.

[0026] Please see Figure 2 and Figure 3 As shown, the bidirectional threaded rod 501 is threadedly connected to the nut seat 505, and the nut seat 505 has a threaded hole inside that matches the bidirectional threaded rod 501. By setting up the bidirectional threaded rod 501 and the nut seat 505, and utilizing the threaded connection between the bidirectional threaded rod 501 and the nut seat 505, the bidirectional threaded rod 501 can be rotated. Since the threads at both ends of the bidirectional threaded rod 501 are in opposite directions, the nut seat 505 can drive the snap-fit ​​plate 506 to move horizontally in the opposite direction. This releases the snap-fit ​​between the snap-fit ​​plate 506 and the snap-fit ​​grooves on both sides of the top of the upper mold 507, enabling the upper mold 507 to be disassembled. This facilitates the maintenance or replacement of the upper mold 507, extends the service life of the device, and has strong practicality, making it easy for users to use.

[0027] In use, the user first activates the electric telescopic rod 401, causing its telescopic end to drive the lifting plate 5 to move vertically up and down. Simultaneously, the sleeve 509 presses downwards against the collar 303, compressing the spring 302. This cushions the impact during mold closing, preventing excessive pressure from damaging the lower mold 2. Coolant is then supplied to the cooling pipe 201, cooling the automotive rubber product from the bottom and sides of the mold cavity, achieving cooling and shaping. The cooled coolant, having absorbed heat, flows out from the other end of the cooling pipe 201, enabling circulating cooling. The cooling fan 202 further cools the coolant inside the cooling pipe 201, improving the cooling effect on the automotive rubber product. In terms of temperature efficiency, when internal parts of the upper mold 507 are damaged, rotating the rotating handle 504 drives the second bevel gear 503 to rotate, which in turn drives the first bevel gear 502 to rotate. This, in turn, drives the bidirectional threaded rod 501 to rotate. Since the threads at both ends of the bidirectional threaded rod 501 are in opposite directions, the nut seat 505 drives the snap-fit ​​plate 506 to move horizontally in the opposite direction. This releases the snap-fit ​​between the snap-fit ​​plate 506 and the snap-fit ​​grooves on both sides of the top of the upper mold 507, allowing the upper mold 507 to be disassembled. This facilitates the repair or replacement of the upper mold 507 and extends the service life of the device.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
