[0047] Before describing the mold structure for forming automotive parts in the embodiments of the present invention, its application scenarios are described. The mold structure can be applied to the home appliance industry, the electronics industry, the automotive industry, etc. In the following embodiments, the mold structure applied to the production field of automotive parts in the automotive industry is taken as an example for description.

[0048] It should be noted that in this embodiment, the first workpiece A is a card pin and the second workpiece B is a card seat.

[0049] The following combines Figures 1 - 14 Describe the mold structure and production equipment for forming automotive parts of the present invention. The production equipment includes the above-mentioned mold structure, an injection molding machine, and a material transfer mechanism. The injection molding mold is installed on the injection molding machine by providing a first barrel and a second barrel on the injection molding machine.

[0050] Refer to Figures 1 to 4, according to the present invention, there is provided a mold structure for molding automotive parts, including: a template assembly, the template assembly includes a first template 100 and a second template 200, and the first template 100 and the second template 200 are relatively movable; a plurality of core structures, each core structure includes a first core body 300 and a second core body 400, and the first core body 300 and the second core body 400 cooperate to mold automotive parts; wherein, the first core body 300 is detachably arranged on the first template 100, and the second core body 400 is detachably arranged on the second template 200.

[0051] For the mold structure for molding automotive parts provided by the present invention, by providing a plurality of core structures, the first core body 300 is detachably arranged on the first template 100 correspondingly, and the second core body 400 is detachably arranged on the second template 200 correspondingly. Therefore, the first core body 300 and the second core body 400 of all core structures are made into independent insert structures. When damage occurs during the production process of the injection mold, it is not necessary to take the whole set of molds off the machine, and the insert replacement of the core structure corresponding to the local cavity number can be directly completed on the machine. Moreover, since each core structure is independently arranged, the mold has good heat dissipation, stable mold temperature, short forming cycle, and convenient mold repair.

[0052] Specifically, referring to Figure 1 , Figure 3 , Figure 5 and Figure 6 , in some embodiments of the present invention, the first core body 300 includes a first core monomer 310 and a second core monomer 320. The first core monomer 310 and the second core monomer 320 are detachably connected to the first template 100, and the first core monomer 310 and the second core monomer 320 are arranged side by side independently; the first core monomer 310 cooperates with a part of the structure of the second core body 400 to form a first molding cavity 500 for molding the first workpiece A; the second core monomer 320 cooperates with another part of the structure of the second core body 400 to form a second molding cavity 600 for molding the second workpiece B. Through the above structure, the first core monomer 310 and the second core monomer 320 can be separately and independently manufactured. According to actual needs, different processing technologies and materials can be selected to ensure that each component can meet the required accuracy, strength, and surface quality requirements. Multiple components can be processed and produced simultaneously, thereby shortening the entire manufacturing cycle and improving production efficiency. It should be noted that the above-mentioned detachable connection method can be a bolt connection or the like.

[0053] Specifically, referring to Figure 1 , Figure 3 , Figure 5 and Figure 6In some embodiments of the present invention, the first mold core monomer 310 is provided with a first positioning groove 311, the second mold core monomer 320 is provided with a second positioning groove 321 and a positioning column 322 located in the second positioning groove 321, and the second mold core body 400 is provided with a mold groove 410 and a positioning cavity 420; the first positioning groove 311 and the mold groove 410 cooperate to form a first molding chamber 500, the second positioning groove 321 and the positioning cavity 420 are docked and matched, the positioning column 322 is inserted into the positioning cavity 420, and there is a gap between the side wall of the positioning column 322 and the side wall of the positioning cavity 420 to form a second molding chamber 600. Through the above-mentioned arrangement, the production efficiency is improved. Since the molding operations of two workpieces made of different materials (the first workpiece A and the second workpiece B) can be carried out at the same time, more products can be produced in the same time, which improves the production efficiency. The structural design can complete the molding operations of two products of different shapes or specifications in the same mold, which reduces costs and reduces waste in the production process. It can achieve precise alignment between the first mold core body 300 and the second mold core body 400, providing a reliable foundation for subsequent production and processing, ensuring product quality and production efficiency, and improving production flexibility.

[0054] Specifically, refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 In some embodiments of the present invention, the first mold core monomer 310 is provided with a first glue feeding channel 312, and the second mold core monomer 320 is provided with a second glue feeding channel 323. The first glue feeding channel 312 is correspondingly connected to the first mold groove 311, and the second glue feeding channel 323 is correspondingly connected to the second mold groove 321. The glue feeding routes of the first glue feeding channel 312 and the second glue feeding channel 323 are arranged parallel to the relative moving direction of the first mold core body 300 and the second mold core body 400. Since the first glue feeding channel 312 and the second glue feeding channel 323 are arranged parallel to the moving direction of the first mold core body 300, the uniformity and smoothness of the material when injected into the first molding cavity 500 and the second molding cavity 600 can be effectively ensured, which is conducive to improving the molding quality of the product; the parallel arrangement of the glue feeding channels can reduce the resistance of the material in the process of entering the first molding cavity 500 and the second molding cavity 600, reduce the possibility of loss of automobile parts, and help save production costs and speed up the injection cycle, thereby improving production efficiency.

[0055] It is understandable that Figure 11, in some embodiments of the present invention, the first mold core monomer 310 is provided with a first cooling water channel 313 for introducing a cooling medium, and the second mold core monomer 320 is provided with a second cooling water channel 324 for introducing a cooling medium. The first cooling water channel 313 of the first mold core monomer 310 and the second cooling water channel 324 of the second mold core monomer 320 can both introduce a cooling medium (such as water or other cooling liquids). In this way, the mold core can be cooled by circulating the cooling medium; through the cooling water channel, the cooling medium can absorb the heat generated by the mold core and take away the heat, thereby effectively reducing the temperature of the mold core and maintaining the stability and lifespan of the mold core; by controlling the temperature and flow rate of the cooling medium in the cooling water channel, the processing temperature of the mold core can be precisely controlled.

[0056] Specifically, referring to Figure 2 and Figures 4 to 8 , in some embodiments of the present invention, the second mold core body 400 includes a fixed mold core member 430, a first movable mold core member 440, and a second movable mold core member 450. The fixed mold core member 430, the first movable mold core member 440, and the second movable mold core member 450 are all detachably connected to the second template 200 and are independent of each other; wherein, one side surface of the fixed mold core member 430 facing the first mold core monomer 310 and the opposite side surfaces of the first movable mold core member 440 and the second movable mold core member 450 cooperate to form a mold cavity 410, and the cavity 420 is provided on one side surface of the second movable mold core member 450 facing the second mold core monomer 320. With the above structure, the fixed mold core member 430, the first movable mold core member 440, and the second movable mold core member 450 can be separately manufactured and processed, with flexible manufacturing processes; separate independent manufacturing can, according to actual needs, select different processing techniques and materials to ensure that each component can meet the required accuracy, strength, and surface quality requirements, and multiple components can be processed and produced simultaneously, thereby shortening the entire manufacturing cycle and improving production efficiency.

[0057] Specifically, referring to Figures 5 to 8 , in some embodiments of the present invention, the fixed mold core member 430 and the first mold core monomer 310 are arranged opposite to each other to be used for forming and positioning the opposite two sides of the outer periphery of the first workpiece A, and the first movable mold core member 440 and the second movable mold core member 450 are arranged opposite to each other to be used for forming and positioning the other opposite two sides of the outer periphery of the first workpiece A and the opposite two ends of the first workpiece A along the length direction. By arranging multiple components opposite to each other, the first workpiece A can be better fixed and positioned, ensuring stability and accuracy during the forming process, which is beneficial to improving the forming quality of the product; since the relative arrangement of each component can more accurately position the first workpiece A, the debugging time and the time for adjusting the forming parameters can be reduced, thereby improving production efficiency; through the multi-directional positioning arrangement, the consistency and stability of the first workpiece A during the forming process can be ensured, avoiding product quality problems caused by inaccurate positions.

[0058] It is understandable that, with reference to Figures 6 to 8 , in some embodiments of the present invention, the fixed mold core member 430 is provided with a first recess 431, the first movable mold core member 440 is provided with a second recess 441, and the second movable mold core member 450 is provided with a third recess 451. The first recess 431, the second recess 441 and the third recess 451 cooperate to form a mold cavity 410. Among them, the first movable mold core member 440 moves relative to the fixed mold core member 430 along a first direction, and the second movable mold core member 450 moves relative to the fixed mold core member 430 along a second direction, and the first direction and the second direction are opposite. The designs of the first movable mold core member 440 and the second movable mold core member 450 can be adjusted along different directions, which is convenient for mold closing and demolding, and they can slide along the first direction and the second direction respectively, and adjust their positions relative to the fixed mold core member 430, so as to adapt to the production of workpieces with different shapes and specifications.

[0059] Specifically, in some embodiments of the present invention, the fixed mold core member 430 is provided with a third cooling water channel 432 for introducing a cooling medium, the first movable mold core member 440 is provided with a fourth cooling water channel 442 for introducing a cooling medium, and the second movable mold core member 450 is provided with a fifth cooling water channel 452 for introducing a cooling medium. The third cooling water channel 432 of the fixed mold core member 430, the fourth cooling water channel 442 of the first movable mold core member 440, and the fifth cooling water channel 452 of the second movable mold core member 450 can introduce a cooling medium (such as water or other cooling liquids), and these components can be cooled by circulating the cooling medium to prevent overheating during the injection molding process; during injection molding or other processing, the fixed mold core member 430, the first movable mold core member 440 and the second movable mold core member 450 are also affected by heat. Through the cooling water channels, the cooling medium can absorb the heat generated by them and take away the heat, thereby effectively reducing their temperatures and maintaining their stability and service life; by controlling the temperature and flow rate of the cooling medium in the cooling water channels, the processing temperatures of these components can be accurately controlled.

[0060] Specifically, refer to Figure 11, in this embodiment, the first cooling water channel 313 includes a first cooling inlet section 3131, a first cooling transition section 3132, and a first cooling outlet section 3133 that are connected in sequence; among them, the centerlines of the first glue inlet channel 312, the first cooling inlet section 3131, and the first cooling outlet section 3133 are parallel to each other, and the centerline of the first cooling transition section 3132 is perpendicular to the centerline of the first cooling inlet section 3131 and the centerline of the first cooling outlet section 3133 respectively. With the above structure, the three parts of the first cooling water channel 313 are connected in sequence to ensure that the cooling medium can flow smoothly; starting from the first cooling inlet section 3131, passing through the first cooling transition section 3132, and finally reaching the first cooling outlet section 3133, a complete flow path is formed; the parallel arrangement of the centerlines of the first glue inlet channel 312, the first cooling inlet section 3131, and the first cooling outlet section 3133 can simplify the structural design, improve the feasibility of the manufacturing process, and is beneficial to the transmission and flow of the cooling medium in the water channel; the centerline of the first cooling transition section 3132 is perpendicular to the centerlines of the first cooling inlet section 3131 and the first cooling outlet section 3133 respectively, realizing the transition from horizontal flow to vertical flow. This transition design can effectively reduce the fluid resistance and pressure loss and improve the cooling effect.

[0061] It should be noted that, similarly, the second cooling water channel 324, the second cooling water channel 324, the third cooling water channel 432, the fourth cooling water channel 442, and the fifth cooling water channel 452 are all similar in shape to the first cooling water channel 313 and still have the above effects, which will not be elaborated here.

[0062] It can be understood that with reference to Figure 12, in some embodiments of the present invention, the first template 100 is provided with a first glue inlet 110 for injecting a first material and a second glue inlet 120 for injecting a second material. The first glue inlet channel 312 is connected to the first glue inlet 110, and the second glue inlet channel 323 is connected to the second glue inlet 120. By providing the first glue inlet 110 and the second glue inlet 120 on the same injection mold template, i.e., the first template 100, the first glue inlet 110 injects the first material, the second glue inlet 120 injects the second material, and the first glue inlet 110 is configured to communicate with the first molding chamber 500, and the second glue inlet 120 is configured to communicate with the second molding chamber 600. The two materials are fed in through the first glue inlet 110 and the second glue inlet 120 respectively, realizing the production of automotive parts made of two different materials on the same injection mold, that is, forming the first workpiece A (for example: a thumbtack), and forming the second workpiece B (for example: a card seat), which is beneficial to reducing production costs and occupying less space. Moreover, through the corresponding respective communication paths of the two materials, they are independent of each other, which is beneficial to avoiding interference between the first workpiece A and the second workpiece B during the injection molding process; secondly, the core structure is detachably arranged, which is convenient for maintenance and better. Quality inspection and adjustment can be carried out separately to ensure that the accuracy and quality of each component meet the requirements. At the same time, if the mold needs to be adjusted or improved, specific components can also be modified or replaced more conveniently.

[0063] It can be understood that, referring to Figure 12 , in some embodiments of the present invention, the first template 100 has a first plate surface and a second plate surface. The first glue inlet 110 is provided on the first plate surface, and the second glue inlet 120 is provided on the second plate surface; wherein, the first plate surface and the second plate surface are perpendicular to each other. Correspondingly, it can be understood that in this embodiment, the above-mentioned first glue inlet 110 is located on the side wall plate surface of the first template 100, and the second glue inlet 120 is located on the top plate surface of the first template 100. Through the above structure, it is beneficial to avoid interference between the first glue inlet 110 and the second glue inlet 120 during glue injection, which can improve the efficiency and stability of injection molding, reduce the downtime and debugging time of the production line caused by interference, and improve production efficiency.

[0064] It can be understood that, referring to Figure 13As shown, in some embodiments of the present invention, a first runner structure 700 is provided between the first glue inlet 110 and the first molding chamber 500, and a second runner structure 800 is provided between the second glue inlet 120 and the second molding chamber 600, and there is a spacing between the first runner structure 700 and the second runner structure 800. With the above structure, through the first runner structure 700 and the second runner structure 800, the path and speed of the flowing rubber material can be precisely controlled, which helps to ensure the uniform distribution and accurate injection of materials during the molding process; by setting the first runner structure 700 and the second runner structure 800 and leaving a spacing between them, the pressure balance can be achieved, which helps to avoid the generation of uneven pressure distribution during the injection process, thereby improving the quality and consistency of the product, and different materials can be separated or isolated to avoid heat transfer between the first runner structure 700 and the second runner structure 800, which is suitable for the separate injection molding of two materials with different melting points to ensure that no mixing or cross-contamination occurs between different materials.

[0065] Specifically, referring to Figure 13 , in some embodiments of the present invention, in the horizontal cross-section of the first template 100, the first runner structure 700 is arranged around a partial area of the second runner structure 800. With the above structure, the space of the first template 100 can be utilized most reasonably, making the structure more compact and conducive to reducing the volume of the first template 100. Of course, the above first runner structure can also be arranged around all areas of the second runner structure 800, that is, the first runner structure 700 surrounds the second runner structure 800 in a ring shape.

[0066] It should be noted that the above first barrel corresponds to the first glue inlet 110, and the first material (rubber material) is injected into the first glue inlet 110 through the corresponding injection mechanism, the second barrel corresponds to the second glue inlet 120, and the second material (rubber material) is injected into the second glue inlet 120 through the corresponding injection mechanism; after the workpiece is molded, the mold is demolded, and the first workpiece A and the second workpiece B are assembled and removed from the mold through the material transfer mechanism.

[0067] It should be noted that, in some embodiments of the present invention, it can be understood that the corresponding number of workpieces is produced according to the number of mold core structures. For example, 48 sets of buckle components can be produced, that is, 48 first workpieces A and 48 second workpieces B are produced. Of course, other numbers of sets of mold core structures can also be set, such as producing 36 sets or 64 sets of buckle components, which are not limited herein.

[0068] It can be understood that, referring to Figure 14 , in some embodiments of the present invention, the production equipment further includes a clamping device C and a manipulator device. The clamping device C is used to remove the automotive parts located on the injection mold, and the automotive parts are removed from the clamping device C through the manipulator device and unloaded to the aggregate area.

[0069] Specifically, it should be noted that in the embodiment of the present invention, the clamping device C is configured to be rotatable. The clamping device C can be moved to cooperate with the injection mold. For example, the injection mold is located below the clamping device C, and the manipulator device is located above the injection mold. The clamping device C moves to the corresponding position for cooperation with the injection mold, clamps the material, and then resets to the position corresponding to the manipulator device.

[0070] Specifically, in this embodiment, the clamping device C is provided with a first clamping position a, a second clamping position b, a third clamping position c, and a fourth clamping position d. The first clamping position a and the second clamping position b are on the same side, and the third clamping position c and the fourth clamping position d are on the other opposite same side.

[0071] The specific working process is as follows:

[0072] Refer to Figure 14 , after the injection mold performs the first injection molding, the first clamping position a corresponds to the first workpiece A, and the second clamping position b corresponds to the second workpiece B. The first workpiece A is pushed to the first clamping position a through the first ejector pin structure, and the first clamping position a clamps the first workpiece A; while the second ejector pin structure pushes the second workpiece B away from the injection mold, and it is collected through the corresponding material collecting device for subsequent processing;

[0073] Refer to Figure 14 , after the injection mold performs the second injection molding, at the same time, the clamping group rotates relative to the injection mold, so that the first clamping position a rotates to the position aligned with the second workpiece B, the third clamping position c replaces the position of the fourth clamping position d, and the fourth clamping position d rotates to the position aligned with the first workpiece A. The first workpiece A after the second injection molding is pushed to the fourth clamping position d through the first ejector pin structure and clamped. The second workpiece B after the second injection molding is pushed to the first clamping position a through the second ejector pin structure, so that the second workpiece B is sleeved on a part of the structure of the first workpiece A on the first clamping position a and is clamped and matched to form an automotive part;

[0074] Refer to Figure 14 , after the injection mold performs the third injection molding, at the same time, the clamping group then rotates relative to the material taking area. The first clamping position a clamps the assembled automotive part and moves the automotive part away through the manipulator device. The second clamping position b replaces the position of the third clamping position c, and the third clamping position c switches to the position aligned with the first workpiece, and the fourth clamping position d rotates to the position aligned with the second workpiece B. The first workpiece A is pushed to the third clamping position c through the first ejector pin structure and clamped, and the second workpiece B is pushed to the fourth clamping position d through the second ejector pin structure, so that the second workpiece B is sleeved on the first workpiece A on the fourth clamping position d;

[0075] Therefore, through the above structure, the assembly of auto parts is completed, the processes of manual assembly and unloading are reduced, and the labor intensity is lowered.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
