Description

Technical Field

[0001] This utility model relates to the field of automotive rubber mold technology, and in particular to a convenient mold for processing automotive rubber parts. Background Technology

[0002] Automotive rubber parts processing molds are specialized molding tools used to manufacture automotive rubber parts. Through processes such as injection molding and compression molding, rubber materials are processed into functional parts such as seals, shock absorbers, and protectors.

[0003] Compression vulcanization is a common method in rubber processing. The specific process involves placing the rubber compound into a closed mold cavity, applying pressure and heating using equipment such as a flatbed vulcanizing machine, causing the compound to undergo a vulcanization and cross-linking reaction under high temperature and pressure, ultimately forming a rubber product that conforms to the shape of the mold cavity. This process is particularly suitable for producing complex rubber molded products such as gaskets and shock-absorbing rings.

[0004] However, traditional automotive rubber parts processing molds mostly use compression molding vulcanization process, and their internal structure is often designed to be complex, with densely distributed flow channels, grooves and inserts, which makes it very easy for the molded rubber parts to get stuck deep in the mold cavity, making demolding difficult.

[0005] For example, engine oil seal molds often use multi-lobed parting structures with complex lip cavities, and the vulcanized rubber sealing rings are easily embedded in the gaps of the parting surface; shock absorber bushing molds require nested slots due to the built-in metal skeleton, and the rubber is prone to forming negative pressure adsorption with the slots after vulcanization shrinkage; while the barbed anti-detachment grooves and continuous bending flow channels of car door sealing strip molds will all increase the adhesion between the rubber parts and the mold, resulting in time-consuming and labor-intensive manual unloading, and even causing product tearing or mold damage. Utility Model Content

[0006] This utility model discloses a convenient material cutting mold for processing automotive rubber parts, aiming to solve the technical problem that the internal structure of the molding vulcanization process is often complex, with dense distribution of flow channels, grooves and inserts, which makes the molded rubber parts easily stuck deep in the mold cavity and difficult to demold.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A convenient die for processing automotive rubber parts includes an upper die, a middle plate, and a lower die. The middle plate includes a first assembly plate, a second assembly plate, a third assembly plate, a fourth assembly plate, and a fifth assembly plate. It also includes:

[0009] Combination mechanism: The combination mechanism is set on the top outer wall of the middle plate. The top outer wall of the middle plate is provided with two sets of equidistant limiting grooves and limiting holes. The bottom outer wall of the upper mold is provided with two sets of equidistant limiting blocks. The top outer wall of the lower mold is provided with two sets of equidistant limiting rods. The limiting blocks are in contact with the bottom inner wall of the limiting grooves. The limiting rods are inserted into the circumferential inner wall of the limiting holes.

[0010] Auxiliary mechanism: The auxiliary mechanism is disposed on the outer walls of both sides of the middle plate.

[0011] In this case, the middle plate is divided into a first assembly plate, a second assembly plate, a third assembly plate, a fourth assembly plate, and a fifth assembly plate. Limiting grooves and limiting holes are set to cooperate with the limiting blocks of the upper mold and the limiting rods of the lower mold to ensure mold closing accuracy. The combination mechanism achieves rapid positioning through mechanical interlocking, avoiding flash or mold misalignment problems caused by misalignment in traditional molds. This detachable modular design makes it easier to cut rubber parts and improves the flexibility of the mold.

[0012] In a preferred embodiment, the auxiliary mechanism includes four fixing blocks, which are respectively hinged to the outer walls of the first assembly plate and the second assembly plate. Slots are provided on the outer walls of both sides of the middle plate, and connecting brackets are inserted into the inner walls of the slots.

[0013] Specifically, the fixing block is hinged to both sides of the assembly plate and cooperates with the connecting frame in the slot to provide lateral locking force, which facilitates the removal of the five modules containing rubber parts after the material is molded and vulcanized, thus enabling the unloading of the parts.

[0014] As described above, a convenient material-cutting mold for automotive rubber parts includes an upper mold, a middle plate, and a lower mold.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] The present invention discloses a convenient material cutting mold for automotive rubber parts, which is mainly used in the molding and vulcanization process. Its internal structure is often complex, with densely distributed channels, grooves and inserts, which makes it easy for the molded rubber parts to get stuck deep in the mold cavity, making demolding difficult.

[0022] Reference Figure 1 , Figure 2 and Figure 3A convenient mold for processing automotive rubber parts includes an upper mold 1, a middle plate, and a lower mold 3. The middle plate includes a first assembly plate 2, a second assembly plate 6, a third assembly plate 7, a fourth assembly plate 8, and a fifth assembly plate 9. The mold also includes: a combination mechanism: the combination mechanism is located on the top outer wall of the middle plate, and the top outer wall of the middle plate has two sets of equidistantly arranged limiting grooves 12 and limiting holes 11. The bottom outer wall of the upper mold 1 has two sets of equidistantly arranged limiting blocks 18, and the top outer wall of the lower mold 3 has two sets of equidistantly arranged limiting rods 16. The limiting blocks 18 contact the bottom inner wall of the limiting grooves 12, and the limiting rods 16 are inserted into the circumferential inner wall of the limiting holes 11. An auxiliary mechanism: the auxiliary mechanism is located on both sides of the outer wall of the middle plate.

[0023] The middle plate is positioned between the upper mold 1 and the lower mold 3.

[0024] In a specific implementation, the middle plate is divided into a first assembly plate 2, a second assembly plate 6, a third assembly plate 7, a fourth assembly plate 8, and a fifth assembly plate 9. Limiting grooves 12 and limiting holes 11 are provided to cooperate with the limiting blocks 18 of the upper mold 1 and the limiting rods 16 of the lower mold 3 to ensure mold closing accuracy. The combination mechanism achieves rapid positioning through mechanical interlocking, avoiding flash or misalignment problems caused by misalignment in traditional molds. This detachable modular design makes it easier to cut rubber parts and improves the flexibility of the mold.

[0025] Reference Figure 2 In a preferred embodiment, the first assembly plate 2, the second assembly plate 6, and the third assembly plate 7 constitute a first module, and the third assembly plate 7, the fourth assembly plate 8, and the fifth assembly plate 9 constitute a second module. The top outer wall of both the first module and the second module is provided with a mating groove 13, and the bottom inner wall of the mating groove 13 is provided with three equal-distance first molding grooves 14, and the bottom inner wall of the first molding grooves 14 is provided with three connecting holes 15.

[0026] Specifically, the middle plate is divided into a first module and a second module. Each module has a docking groove 13 and a molding groove on its top to achieve modular production. This split design allows for the individual replacement of damaged blocks, reducing maintenance costs.

[0027] Reference Figure 2 and Figure 3 In a preferred embodiment, two molding plates 19 are provided on the bottom outer wall of the upper mold 1, and three third molding grooves 20 arranged at equal intervals are provided on the bottom outer wall of the molding plates 19. Three connecting posts 21 are provided on the bottom inner wall of the molding grooves, and six sets of second molding grooves 17 are provided on the top outer wall of the lower mold 3.

[0028] The first molding groove 14, the second molding groove 17, the third molding groove 20, and the connecting hole 15 are used together.

[0029] The upper mold 1 has a molding plate 19 with a third molding groove 20 and a connecting post 21, and the lower mold 3 has a second molding groove 17, forming a multi-layer nested cavity. This structure solves the problem of insufficient filling of deep cavity parts by increasing the flow path of the rubber material. At the same time, the connecting post 21 enhances the uniformity of force during ejection. The synergistic relationship between the first molding groove 14, the second molding groove 17, the third molding groove 20 and the connecting hole 15 ensures the fluidity of the rubber material in the complex cavity. By optimizing the flow channel layout, the scorching or under-curing problems caused by excessively long flow channels in traditional molds are avoided.

[0030] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, the auxiliary mechanism includes four fixing blocks 5, which are respectively hinged to the outer walls of the first assembly plate 2 and the second assembly plate 6. Slots 10 are provided on the outer walls of both sides of the middle plate, and connecting brackets 4 are inserted into the inner walls of the slots 10.

[0031] Specifically, the fixing block 5 is hinged to both sides of the assembly plate and cooperates with the connecting bracket 4 in the slot 10 to provide lateral locking force, so that after the material is molded and vulcanized, the five modules containing the rubber parts can be taken out together to realize the unloading of the parts.

[0032] Reference Figure 2 and Figure 4 In a preferred embodiment, the length of the fixing block 5 is greater than the thickness of the connecting frame 4. The greater length of the fixing block 5 than the thickness of the connecting frame 4 can better intercept the connecting frame 4 inside the slot 10 and effectively prevent the connecting frame 4 from slipping off.

[0033] Working principle: In use, the upper mold 1, middle plate and lower mold 3 are first assembled according to the corresponding relationship of the limiting groove 12, limiting hole 11 and limiting block 18 and limiting rod 16. The mechanical interlock of the combination mechanism realizes rapid positioning. Then, the preheated rubber material is put into the cavity formed by the first molding groove 14, the second molding groove 17 and the third molding groove 20. Pressure is applied and heated by the flat vulcanizing machine so that the rubber material completes the vulcanization and cross-linking reaction under high temperature and high pressure. After vulcanization, the middle plate and the rubber parts on it are taken out as a whole by the connecting frame 4 of the auxiliary mechanism to realize rapid material unloading. The connecting frame 4 is pulled out from the slot 10 by rotating the fixing block 5. Finally, the first assembly plate 2, the second assembly plate 6, the third assembly plate 7, the fourth assembly plate 8 and the fifth assembly plate 9 are separated and the finished rubber parts are taken out.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
