The production equipment includes the above-mentioned injection mold, an injection molding machine and a material transfer mechanism. The injection mold is installed on the injection molding machine by arranging a first barrel and a second barrel on the injection molding machine.

[0059] The communication path between the first glue inlet 110 and the first molding structure and the communication path between the second glue inlet 120 and the second molding structure are independent of each other.

[0060] The present invention provides an injection mold for automobile accessories. A first glue inlet 110 and a second glue inlet 120 are provided on the same injection template, i.e., a first template 100. The first glue inlet 110 is injected with a first material, and the second glue inlet 120 is injected with a second material. The first glue inlet 110 is configured to be connected to a first molding structure, and the second glue inlet 120 is configured to be connected to a second molding structure. The two materials are injected from the first glue inlet 110 and the second glue inlet 120 respectively, thereby realizing the production of automobile accessories made of two different materials on the same injection mold, i.e., molding a first workpiece A (e.g., a card pin) and molding a second workpiece B (e.g., a card seat), which is beneficial to reducing production costs and reducing occupied space. Moreover, the two materials have corresponding respective communication paths and 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.

[0061] It should be noted that the first barrel corresponds to the first glue inlet 110, and the first material (glue) is injected into the first glue inlet 110 through the corresponding glue injection mechanism, and the second barrel corresponds to the second glue inlet 120, and the second material (glue) is injected into the second glue inlet 120 through the corresponding glue injection mechanism; after the workpiece is formed, the mold is demolded, and the first workpiece A and the second workpiece B are assembled and moved away from the mold through the material moving mechanism.

[0062] It is understandable that, referring to Figure 1 , Figure 2 ,and Figure 3 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 arranged on the first plate surface, and the second glue inlet 120 is arranged on the second plate surface; wherein the first plate surface and the second plate surface are perpendicular to each other. Accordingly, it can be understood that, in this embodiment, the 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 helpful 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 production line downtime and debugging time caused by interference, and improve production efficiency.

[0063] Of course, the first glue inlet 110 and the second glue inlet 120 are not limited to being arranged at different positions of the first template 100. The first glue inlet 110 and the second glue inlet 120 can also be arranged on the same board surface of the first template 100, so that the first glue inlet 110 and the second glue inlet 120 do not interfere with each other during glue injection.

[0064] It is understandable that, referring to Figures 3 to 6As shown, in some embodiments of the present invention, a first flow channel structure 300 is provided between the first glue inlet 110 and the first molding structure, a second flow channel structure 400 is provided between the second glue inlet 120 and the second molding structure, and there is a distance between the first flow channel structure 300 and the second flow channel structure 400. With the above structure, the path and speed of the flowing rubber can be accurately controlled through the first flow channel structure 300 and the second flow channel structure 400, which helps to ensure the uniform distribution and accurate injection of the material during the molding process; by providing the first flow channel structure 300 and the second flow channel structure 400 and leaving a distance between them, pressure balance can be achieved, which helps to avoid 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 flow channel structure 300 and the second flow channel structure 400, which is suitable for separate injection molding of two materials with different melting points to ensure that there is no mixing or cross contamination between different materials.

[0065] Specifically, refer to Figure 5 and Figure 6 In some embodiments of the present invention, in a horizontal cross section of the first template 100, the first flow channel structure 300 is arranged around a portion of the second flow channel structure 400. With the above structure, the space of the first template 100 can be reasonably utilized to the greatest extent, making the structure more compact and helping to reduce the volume of the first template 100. Of course, the above first flow channel structure can also be arranged around all areas of the second flow channel structure 400, that is, the first flow channel structure 300 surrounds the second flow channel structure 400 in a ring shape.

[0066] Specifically, refer to Figure 4 , Figure 5 and Figure 6In the present embodiment, the first flow channel structure 300 includes: a first main flow channel 310, the first main flow channel 310 is connected to the first glue inlet 110, and the first main flow channel 310 is provided with a plurality of first diversion positions 311; a first diversion channel 320, the plurality of first diversion channels 320 correspond to and are connected to the plurality of first diversion positions 311 one by one, the first diversion channel 320 is provided with two first branch ends 321, each first branch end 321 is correspondingly connected to a first branch channel 322, and the first branch channel 322 is uniformly distributed with a plurality of first branch openings 3221 along its length direction; wherein, the first molding structure is provided with a plurality of, the plurality of first branch openings 3221 are matched one by one with the partial structures of the plurality of first molding structures located on the first template 100, and the first branch openings 3221 are connected with the partial structures of the first molding structure.

The above structure is used to make the time for the glue fluid to enter each first molding structure through the first flow channel structure 300 consistent, so that the flow path length effect on each first workpiece A is basically the same, which is conducive to ensuring that the molding time of each first workpiece A is relatively consistent, and is conducive to improving the production process of product quality stability and consistency.

[0068] Specifically, refer to Figure 5 and Figure 6In this embodiment, the first flow channel structure 300 also includes a first glue inlet flow channel 330 connected to the middle part of the first main flow channel 310, so as to further facilitate the molding time of each first workpiece A to be relatively consistent, which is beneficial to the production process of improving product quality stability and consistency; further, the center line of the first glue inlet flow channel 330 is perpendicular to the center line of the first main flow channel 310, the center line of the first branch position 311 is perpendicular to the center line of the first branch flow channel 320, the center line of the first branch end 321 is perpendicular to the center line of the first branch flow channel 322, and the center line of the first branch flow port 3221 is perpendicular to the center line of the first branch flow channel 322. Through the above arrangement, the rubber material moves in a vertical direction when flowing in the straight plane direction, so that the rubber material rolls, so that the temperature of the rubber material passing through the first flow channel structure 300 is balanced, which is beneficial to pressure balance, and further the rubber material is evenly injected into each first molding structure, which is beneficial to keep the time for the rubber fluid to enter each first molding structure through the first flow channel structure 300 consistent.

[0069] Specifically, refer to Figure 4 , Figure 5 and Figure 6 In the present embodiment, the second flow channel structure 400 includes: a second main flow channel 410, the second main flow channel 410 is connected to the second glue inlet 120, and the second main flow channel 410 is provided with a plurality of second diversion positions 411; a second diversion channel 420, the plurality of second diversion channels 420 are in one-to-one correspondence with and connected to the plurality of second diversion positions 411, the second diversion channel 420 is provided with two second branch ends 421, each second branch end 421 is correspondingly connected to a second branch flow channel 422, and the second branch flow channel 422 is uniformly distributed with a plurality of second branch openings 4221 along its length direction; wherein, the second molding structure is provided with a plurality of, the plurality of second branch openings 4221 are in one-to-one correspondence with the partial structures of the plurality of second molding structures located on the first template 100, and the second branch openings 4221 are connected to the partial structures of the second molding structure. By adopting the above structure, through the design of the second main channel 410 and the second branch channel 420, the diversion and control of the rubber fluid can be achieved, thereby achieving precise control of the flow of the rubber fluid during the molding process; the setting of the second branch end 421 and the second branch port 4221 can realize the distribution and feeding of the rubber fluid in different directions.

[0070] Specifically, refer to Figure 5In this embodiment, the distance from each second flow branch position 411 to the second glue inlet 120 is equal; the distance from each second branch end 421 to the second flow branch position 411 is equal; wherein the second branch end 421 is connected to the middle of the second branch channel 422. The above structure is used to make the time for the glue fluid to enter each second molding structure through the second flow channel structure 400 consistent, so that the flow path length effect on each second workpiece B is basically consistent, thereby ensuring that the molding time of each second workpiece B is relatively consistent, and improving the production process of product quality stability and consistency.

[0071] Specifically, refer to Figure 5 and Figure 6 In this embodiment, the second flow channel structure 400 also includes a second glue inlet flow channel 430 connected to the middle part of the second main flow channel 410, so as to further facilitate the molding time of each second workpiece B to be relatively consistent, which is beneficial to the production process of improving the stability and consistency of product quality; further, the center line of the second glue inlet flow channel 430 is perpendicular to the center line of the second main flow channel 410, the center line of the second branch position 411 is perpendicular to the center line of the second branch flow channel 420, the center line of the second branch end 421 is perpendicular to the center line of the second branch flow channel 422, and the center line of the second branch flow port 4221 is perpendicular to the center line of the second branch flow channel 422.

[0072] It is understandable that, referring to Figure 4 , Figure 5 and Figure 6In some embodiments of the present invention, there are gaps between the first main channel 310 and the second main channel 410, between the first branch channel 320 and the second branch channel 420, and between the first branch port 3221 and the second branch port 4221 to avoid heat transfer between the first channel structure 300 and the second channel structure 400, which is suitable for separate injection molding of two materials with different melting points. In this way, the first channel structure 300 and the second channel structure 400 can be integrated in the first template 100 to reduce the occupied space. It should be noted that the cross-sectional area of ​​the first main channel 310 is larger than that of the first branch channel 320, and the cross-sectional area of ​​the second main channel 410 is larger than that of the second branch channel 420. Since the cross-sectional areas of the first main channel 310 and the second main channel 410 are larger, the flow rate of the rubber in the first main channel 310 and the second main channel 410 can be relatively low, which is beneficial to improving the molding stability and the quality of the finished product; since the cross-sectional areas of the first branch channel 320 and the second branch channel 420 are relatively small, the rubber diversion ratio can be controlled and adjusted, so as to meet the requirements of the diversion ratio when molding different workpieces, and the amount of raw materials required in the molding process can be relatively reduced, which is beneficial to reducing production costs and improving production efficiency.

[0073] It should be noted that the above-mentioned first flow channel structure 300 and the second flow channel structure 400 are both integrally formed in the first template 100, or in some embodiments, the first flow channel structure 300 and the second flow channel structure 400 can be configured as flow channel pipes assembled in the first template 100, which is not limited here.

[0074] It is understandable that, referring to Figure 7 , Figure 8 and Fig. 9In some embodiments of the present invention, a first mold core unit 800 and a second mold core unit 900 are provided on the first template 100, and a fixed mold core part 500, a first movable mold core part 600 and a second movable mold core part 700 are provided on the second template 200; the first mold core unit 800 is provided with a first mold groove 810, the second mold core unit 900 is provided with a second mold groove 910 and a mold column 920 located in the second mold groove 910, the fixed mold core part 500 is provided with a first concave position 510, the first movable mold core part 600 is provided with a second concave position 610, and the second movable mold core part 700 is provided with a third concave position 710 and a mold cavity 710. 20; the first recess 510, the second recess 610, the third recess 710 cooperate with the first mold groove 810 to form a first molding structure; the second mold groove 910 cooperates with the mold cavity 720, the mold column 920 is inserted into the mold cavity 720, and the side wall of the mold column 920 and the side wall of the mold cavity 720 have a gap to form a second molding structure; wherein, the fixed mold core part 500 is fixed relative to the second template 200, the first movable mold core part 600 slides along the first direction relative to the fixed mold core part 500, and the second movable mold core part 700 slides along the second direction relative to the fixed mold core part 500, and the first direction and the second direction are opposite.

[0075] Through the above structure, the first mold core unit 800, the second mold core unit 900, the fixed mold core part 500, the first movable mold core part 600 and the second movable mold core part 700 can be manufactured and processed separately, and the manufacturing process is flexible; separate independent manufacturing can select different processing technologies and materials according to actual needs to ensure that each component can meet the required accuracy, strength and surface quality requirements, and multiple parts can be processed and produced at the same time, thereby shortening the entire manufacturing cycle and improving production efficiency; in addition, the design of the first movable mold core part 600 and the second movable mold core part 700 can be adjusted along different directions to facilitate film closing and demolding, and they can slide along the first direction and the second direction respectively, and adjust their position relative to the fixed mold core part 500, so as to adapt to the production of workpieces of different shapes and specifications.

[0076] Specifically, in some embodiments of the present invention, the first mold core monomer 800 and the second mold core monomer 900 are detachably provided on the first template 100, and the fixed mold core part 500, the first movable mold core part 600 and the second movable mold core part 700 are detachably provided on the second template 200; after the first mold core monomer 800, the second mold core monomer 900, the fixed mold core part 500, the first movable mold core part 600 and the second movable mold core part 700 are independently manufactured, it is easier to replace and maintain the parts. For example, when a first mold core monomer 800 is damaged, only the part needs to be replaced without replacing the entire mold, which reduces maintenance costs and downtime; the independently manufactured mold parts can be separately inspected and adjusted for quality to ensure that the accuracy and quality of each part meet the requirements. At the same time, if the mold needs to be adjusted or improved, it is also more convenient to modify or replace specific parts.

[0077] In some embodiments of the present invention, the first molding structure is a first molding chamber, and the second molding structure is a second molding chamber. The orthographic projection of the first molding chamber overlaps with the orthographic projection of the second movable mold core 700. Therefore, the spatial structure of the second movable mold core 700 is fully utilized, so that the second movable mold core 700 participates in the first workpiece A and the second workpiece B while also having the function of a sliding structure. In the present invention, two different workpieces are simultaneously molded on a set of molds, which is conducive to reducing the volume of the mold assembly, thereby reducing the volume of the entire injection mold.

[0078] It should be noted that, in some embodiments of the present invention, the first mold core monomer 800, the second mold core monomer 900, the fixed mold core part 500, the first movable mold core part 600 and the second movable mold core part 700 are all multiple, and each first mold core monomer 800, each second mold core monomer 900, each fixed mold core part 500, each first movable mold core part 600 and each second movable mold core part 700 constitute a group of mold core structures. The mold core structure is a plurality of groups. It can be understood that the corresponding number of workpieces is produced according to the number of groups of the mold core structure. For example, referring to Figure 5 , 48 groups of snap-fit ​​components can be produced, that is, 48 ​​first workpieces A and 48 second workpieces B can be produced. Of course, other groups of mold core structures can be set to produce 36 groups, 64 groups of snap-fit ​​components, etc., which are not limited here. In this embodiment, during the assembly process, a side surface away from the first recess 610 on a side wall of the first movable mold core part 600 away from the head end and the tail end cooperates with a side surface close to a side wall of the next adjacent first movable mold core part 600 to form the first recess 610. Therefore, during the assembly process, it is beneficial to further reduce the space.

[0079] It is understandable that, referring to Figures 7 and 8In some embodiments of the present invention, the first mold core monomer 800 is provided with a first glue feeding channel 820, and the second mold core monomer 900 is provided with a second glue feeding channel 930. The first glue feeding channel 820 is correspondingly connected to the first mold groove 810, and the second glue feeding channel 930 is correspondingly connected to the second mold groove 910. The glue feeding routes of the first glue feeding channel 820 and the second glue feeding channel 930 are arranged in parallel with the relative moving direction of the first template 100 and the second template 200. Since the first glue feeding channel 820 and the second glue feeding channel 930 are arranged in parallel with the moving direction of the first template 100 and the second template 200, the uniformity and smoothness of the material when injected into the first molding cavity and the second molding cavity 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 and the second molding cavity, reduce the possibility of material loss, and help save production costs and speed up the injection cycle, thereby improving production efficiency.

[0080] Specifically, in some embodiments of the present invention, the first mold core monomer 800, the second mold core monomer 900, the fixed mold core part 500, the first movable mold core part 600, and the second movable mold core part 700 are all provided with corresponding cooling water channels to facilitate heat dissipation and cooling, effectively reduce the temperature of the mold, and greatly shorten the cooling time of the mold, which can improve production efficiency, reduce the workpiece molding cycle, increase production capacity, and help avoid mold overheating and causing deformation, damage, or shortening the life of the mold. Specifically, the first mold core monomer 800 is provided with a first cooling water channel, the second mold core monomer 900 is provided with a second cooling water channel, the fixed mold core part 500 is provided with a third cooling water channel, the first movable mold core part 600 is provided with a fourth cooling water channel, and the second movable mold core part 700 is provided with a fifth cooling water channel. By setting up multiple cooling water channels, the cooling medium can flow evenly in the injection mold to achieve a comprehensive cooling effect; each cooling water channel is distributed in different components and connected to the corresponding mold core monomer or mold core part, ensuring the cooling uniformity of the entire injection mold; through the circulation of multiple cooling water channels, the heat generated by the mold can be effectively absorbed and quickly taken away; the mold core temperature can be reduced, the heat dissipation effect of the mold can be improved, and the service life of the mold can be extended: by adjusting the flow rate and temperature of the cooling water channel, the temperature of different parts of the mold core assembly can be controlled, which is very important for workpieces that require different temperature zones in specific molding processes, and can ensure the stability of the molding process and product quality.

[0081] Specifically, in this embodiment, the first cooling water circuit includes a first cooling entry section, a first cooling transition section and a first cooling outlet section which are connected in sequence; wherein, the center lines of the first glue inlet channel 820, the first cooling entry section and the first cooling outlet section are arranged in parallel, and the center line of the first cooling transition section is respectively perpendicular to the center line of the first cooling entry section and the center line of the first cooling transition section. Through the above structure, the three parts of the first cooling water circuit are connected in sequence to ensure that the cooling medium can flow smoothly; starting from the first cooling entry section, passing through the first cooling transition section, and finally reaching the first cooling outlet section, a complete flow path is formed; the center lines of the first glue inlet channel 820, the first cooling entry section and the first cooling outlet section are arranged in parallel, which can simplify the structural design, improve the feasibility of the manufacturing process, and facilitate the transmission and flow of the cooling medium in the water circuit; the center line of the first cooling transition section is respectively perpendicular to the center line of the first cooling entry section and the first cooling outlet section, realizing the transition from horizontal flow to vertical flow. This transition design can effectively reduce the resistance and pressure loss of the fluid and improve the cooling effect.

[0082] It should be noted that, similarly, the second cooling water channel, the second cooling water channel, the third cooling water channel, the fourth cooling water channel and the fifth cooling water channel are similar in shape to the first cooling water channel, and they still have the above-mentioned effects, which will not be elaborated here.

[0083] It is understandable that, referring to Fig. 9 In some embodiments of the present invention, the production equipment also includes a clamping device C and a manipulator device. The clamping device C is used to remove the automobile parts located on the injection mold. The automobile parts are moved away from the clamping device C by the manipulator device and unloaded to the gathering area.

[0084] Specifically, it should be noted that, in an embodiment of the present invention, the clamping device C is configured to be rotatable, and 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 injection mold cooperation position to clamp the material and reset to the position corresponding to the manipulator device.

[0085] 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 located on the same side, and the third clamping position c and the fourth clamping position d are located on another opposite same side.

[0086] The specific workflow is as follows:

[0087] Reference Fig.10After 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 by the first ejector pin structure, and the first clamping position a holds the first workpiece A; and the second ejector pin structure pushes the second workpiece B away from the injection mold, and the workpiece is collected by the corresponding collecting device for subsequent processing;

[0088] Reference Fig.10 When 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 a 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 a position aligned with the first workpiece A, and the first workpiece A after the second injection molding is pushed to the fourth clamping position d through the first ejector structure and clamped, and the second workpiece B after the second injection molding is pushed to the first clamping position a through the second ejector structure, so that the second workpiece B is covered with the partial structure of the first workpiece A on the first clamping position a and is snap-fitted to form an automotive accessory;

[0089] Reference Fig.10 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 auto parts, and moves away from the auto parts through the manipulator device, the second clamping position b replaces the third clamping position c, and the third clamping position c is switched to the position aligned with the first workpiece, 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 by the first ejector structure, and clamped, and the second workpiece B is pushed to the fourth clamping position d by the second ejector structure, so that the second workpiece B is covered with the first workpiece A on the fourth clamping position d;

[0090] Therefore, through the above structure, the assembly of automobile parts is completed, the process of manual assembly and unloading is reduced, and the labor level is reduced.

[0091] 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 it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
