In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
[0053] Combine the following Figure 1-Figure 10 The invention describes an injection mold and a production equipment for automobile parts production.
[0054] An embodiment of one aspect of the present invention, referring to Figure 1 , Figure 2 and Figure 5 As shown, an injection mold for the production of automotive parts is provided, including a first mold body 100 and a second mold body 200, the first mold body 100 has a molding surface 110, the second mold body 200 and the first mold body 100 can move relatively, and the molding surface 110 and the second mold body 200 are used to form automotive parts together; wherein, the first mold body 100 and the second mold body 200 are both provided with independent cooling pipelines 300, and the cooling pipelines 300 are integrally formed with the first mold body 100 or the second mold body 200.
[0055] It is understandable that in this embodiment, by adopting multiple sets of independent cooling pipeline 300 structures, each mold core body can be cooled by adding cooling water channels. The advantage of this design is that each mold core body can adjust the flow and temperature individually to meet different molding requirements, thereby achieving more accurate temperature control and improving the stability of temperature control, thereby improving product accuracy, better cooling effect, and shortening the molding cycle. At the same time, this design can also avoid interference between different mold core bodies, further improving temperature stability and accuracy stability.
[0056] In addition, the cooling pipeline 300 is integrally formed in the first mold body 100 or the second mold body 200, that is, the pipeline is integrally formed in the first mold body 100 or the second mold body 200. This design can reduce the risk of air leakage at the pipeline connection and can better protect the cooling pipeline 300 from external damage. This one-piece molding design can also reduce the manufacturing difficulty of the mold and increase the service life of the mold.
[0057] According to one embodiment of the present invention, referring to Figure 1 , Figure 6 and Fig. 9 As shown, the first mold core body 100 includes a first mold core monomer 120 and a second mold core monomer 130, the first mold core monomer 120 and the second mold core monomer 130 are independently arranged side by side, and the side surfaces of the first mold core monomer 120 and the second mold core monomer 130 facing the second mold core body 200 cooperate to form a molding surface 110; the first mold core monomer 120 cooperates with a partial structure of the second mold core body 200 to form a first molding cavity 400 for molding a first workpiece A; the second mold core monomer 130 cooperates with another partial structure of the second mold core body 200 to form a second molding cavity 500 for molding a second workpiece B;
[0058] The cooling pipeline 300 includes a first cooling water channel 310 and a second cooling water channel 320. The first cooling water channel 310 is disposed in the first mold core body 100, and the second cooling water channel 320 is disposed in the second mold core unit 130. The first cooling water channel 310 and the second cooling water channel 320 are disposed independently of each other.
[0059] It can be understood that, in this embodiment, the first mold core monomer 120 cooperates with a part of the structure of the second mold core body 200 to form a first molding cavity 400 for molding the first workpiece A, which means that the first mold core monomer 120 cooperates with some parts of the structure of the second mold core body 200 to form a space for injection molding the first workpiece A. At the same time, the second mold core monomer 130 cooperates with another part of the structure of the second mold core body 200 to form a second molding cavity 500 for molding the second workpiece B, which means that the second mold core monomer 130 and other parts of the structure of the second mold core body 200 also cooperate with each other to form another space for injection molding the second workpiece B.
[0060] The materials of the first workpiece A and the second workpiece B can be the same or different. Such a design allows two different workpieces to be molded simultaneously during one injection molding process. Different workpieces can be molded through independent molding chambers, and efficient production can be carried out in the same mold to improve production efficiency. One injection mold can produce two workpieces. Compared with producing each workpiece with a separate injection mold, the space occupied by the injection mold can be reduced and the production cost can be reduced.
[0061] Furthermore, the cooling circuit 300 includes a first cooling water circuit 310 and a second cooling water circuit 320. The first cooling water circuit 310 is arranged on the first mold core monomer 120, and the second cooling water circuit 320 is arranged on the second mold core monomer 130. The first cooling water circuit 310 and the second cooling water circuit 320 are arranged independently of each other to cool the first mold core monomer 120 and the second mold core monomer 130 separately and independently to meet different molding requirements. Through the independent cooling circuit 300, the temperature of each mold core body can be more accurately controlled, thereby improving the quality and production efficiency of injection molding. And because the molding temperature and molding conditions of the first molding chamber 400 and the second molding chamber 500 are different, the independent first cooling water circuit 310 and the second cooling water circuit 320 are arranged to meet the cooling requirements of different workpieces, accurately control the temperature and cooling conditions of each workpiece, avoid deformation and quality problems of the workpiece, shorten the molding cycle and improve production efficiency, and ensure the consistency and stability of the workpiece.
[0062] According to one embodiment of the present invention, referring to Figure 1 As shown, at least one of the first cooling water channel 310 and the second cooling water channel 320 is provided in plurality to fully cool the first mold core monomer 120 and the second mold core monomer 130 and improve the cooling efficiency. If only one cooling water channel is provided, uneven temperature may result, causing problems such as deformation and defects of the workpiece.
[0063] In the specific design, the number, location and size of cooling water channels can be reasonably set according to the mold size, shape and characteristics of the injection molding material. Generally speaking, the cooling water channels need to be evenly distributed on the mold and as close to the workpiece surface as possible to minimize the temperature of the workpiece. In addition, the flow rate and temperature of the cooling water channels need to be controlled to ensure that the temperature and cooling time of each workpiece can be effectively controlled.
[0064] In an optional embodiment, there are multiple first cooling water channels 310, and the multiple first cooling water channels 310 are arranged on two opposite sides of the first molding chamber 400. By arranging multiple cooling water channels on two opposite sides of the first molding chamber 400, the cooling water can cover the entire area of the first molding chamber 400 as much as possible, thereby improving the cooling effect on the first workpiece A. This can effectively reduce the temperature of the first workpiece A, reduce the risk of thermal stress and deformation, and at the same time improve the molding quality and production efficiency of the first workpiece A.
[0065] In another optional embodiment, there are multiple second cooling water channels 320, and the multiple second cooling water channels 320 are arranged on two opposite sides of the second molding chamber 500. By arranging multiple cooling water channels on two opposite sides of the second molding chamber 500, the cooling water can cover the entire area of the second molding chamber 500 as much as possible, thereby improving the cooling effect on the second workpiece B. This can effectively reduce the temperature of the second workpiece B, reduce the risk of thermal stress and deformation, and improve the molding quality and production efficiency of the second workpiece B.
[0066] According to one embodiment of the present invention, referring to Figure 1 , Figure 3 and Fig. 9 As shown, the first cooling water channel 310 includes a first main flow channel 311, a first inlet section 312, a first cooling section 313 and a first outlet section 314 which are connected in sequence. The first cooling section 313 is arranged corresponding to the first molding chamber 400, and the outlet of the first outlet section 314 is connected to the first main flow channel 311;
[0067] The second cooling water channel 320 includes a second main channel 321 , a second inlet section 322 , a second cooling section 323 and a second outlet section 324 which are connected in sequence. The second cooling section 323 is arranged corresponding to the second molding cavity, and the outlet of the second outlet section 324 is connected to the first main channel 311 .
[0068] It can be understood that, in this embodiment, the first cooling water circuit 310 includes a first main channel 311, a first entry section 312, a first cooling section 313 and a first outlet section 314 which are connected in sequence, and the first cooling section 313 is set for the first molding chamber 400, and finally, the outlet of the first outlet section 314 is connected to the first main channel 311. Such a design can ensure that the cooling water enters the first entry section 312 from the first main channel 311, and then cools the first molding chamber 400 through the first cooling section 313, and finally returns to the first main channel 311 through the outlet of the first outlet section 314, so that the circulating water flow can effectively take away the heat and realize uniform cooling of the first molding chamber 400. Furthermore, the first entry section 312 and the first outlet section 314 at least partially extend into the first mold core monomer 120 for a certain length, so that the first cooling section 313 is as close to the first molding chamber 400 as possible, thereby improving the cooling effect.
[0069] In some embodiments, the first entry section 312 and the first cooling section 313 are arranged vertically, and the first cooling section 313 and the first outlet section 314 are arranged vertically. When the first entry section 312 and the first cooling section 313 are arranged vertically, the cooling water can form a larger flow resistance between the entry section and the cooling section, thereby increasing the time the cooling water stays in the cooling section, thereby improving the cooling effect on the mold. At the same time, the vertical arrangement can also reduce the dead angle during the flow of the cooling water, ensuring that the entire molding chamber can be fully cooled. Similarly, the vertical arrangement of the first cooling section 313 and the first outlet section 314 can also effectively take away heat, so that the cooling water can flow out smoothly after passing through the cooling section, achieving a good cooling effect.
[0070] Similarly, the second cooling water circuit 320 includes a second main channel 321, a second entry section 322, a second cooling section 323 and a second outlet section 324 which are connected in sequence, and the second cooling section 323 is set for the second molding chamber 500, and finally, the outlet of the second outlet section 324 is connected to the second main channel 321. Such a design can ensure that the cooling water enters the second entry section 322 from the second main channel 321, and then cools the second molding chamber 500 through the second cooling section 323, and finally returns to the second main channel 321 through the outlet of the second outlet section 324, so that the circulating water flow can effectively take away the heat and realize uniform cooling of the second molding chamber 500. Furthermore, the second entry section 322 and the second outlet section 324 at least partially extend into the second mold core monomer 130 by a certain length, so that the second cooling section 323 is as close to the second molding chamber 500 as possible, thereby improving the cooling effect.
[0071] In some embodiments, the second entry section 322 and the second cooling section 323 are vertically arranged, and the second cooling section 323 and the second outlet section 324 are vertically arranged. When the second entry section 322 and the second cooling section 323 are vertically arranged, the cooling water can form a larger flow resistance between the entry section and the cooling section, thereby increasing the time that the cooling water stays in the cooling section, thereby improving the cooling effect on the mold. At the same time, the vertical arrangement can also reduce the dead angle during the flow of the cooling water, ensuring that the entire molding chamber can be fully cooled. Similarly, the vertical arrangement of the second cooling section 323 and the second outlet section 324 can also effectively take away heat, so that the cooling water can flow out smoothly after passing through the cooling section, achieving a good cooling effect.
[0072] According to one embodiment of the present invention, referring to Figure 6 , Figure 7 and Figure 8 As shown, the second mold body 200 includes a fixed mold part 210, a first movable mold part 220 and a second movable mold part 230. The fixed mold part 210 and the first mold unit 120 are arranged opposite to each other to form and position the opposite two sides of the periphery of the first workpiece A. The first movable mold part 220 and the second movable mold part 230 are arranged opposite to each other to form and position the other opposite two sides of the periphery of the first workpiece A and the opposite two ends of the first workpiece A along the length direction.
[0073] It can be understood that in this embodiment, the second mold body 200 includes a fixed mold part 210, a first movable mold part 220 and a second movable mold part 230. By arranging multiple parts in opposite directions, the first workpiece A can be better fixed and positioned, ensuring stability and precision in the molding process, which is beneficial to improving the molding 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 molding parameters can be reduced, thereby improving production efficiency; through multi-directional positioning settings, the consistency and stability of the first workpiece A in the molding process can be ensured, avoiding product quality problems caused by inaccurate positioning.
[0074] And through the above structure, the first mold core unit 120, the second mold core unit 130, the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 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 220 and the second movable mold core part 230 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 210, so as to adapt to the production of workpieces of different shapes and specifications.
[0075] Specifically, in some embodiments of the present invention, Figure 1 and Fig.10 As shown, the first mold core monomer 120 and the second mold core monomer 130 are detachably provided on the first mold plate 700, and the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 are detachably provided on the second mold plate 800; after the first mold core monomer 120, the second mold core monomer 130, the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 are independently manufactured, it is easier to replace and maintain the parts. For example, when a first mold core monomer 120 is damaged, only the part needs to be replaced without replacing the entire mold, which reduces the maintenance cost 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.
[0076] Further, refer to Figure 2 and Figure 4 As shown, the cooling circuit 300 also includes a third cooling water circuit 330, a fourth cooling water circuit 340 and a fifth cooling water circuit 350. The third cooling water circuit 330 is arranged on the first movable mold core part 220, the fourth cooling water circuit 340 is arranged on the fixed mold core part 210, and the fifth cooling water circuit 350 is arranged on the second movable mold core part 230. That is, the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 are all provided with independently controlled cooling water circuits, which can be refined according to the heat distribution of different parts of the mold, thereby improving the quality and production efficiency of the molded workpiece. By setting an independent cooling water circuit for each key part, the cooling effect can be better controlled to avoid deformation or quality problems caused by excessive local temperature.
[0077] In some embodiments, each component is provided with a corresponding temperature sensor, and the operating parameters of the cooling water circuit of the component corresponding to the temperature sensor can be controlled according to the detected temperature of the temperature sensor.
[0078] According to one embodiment of the present invention, referring to Figure 7 , Figure 8 and Fig. 9 As shown, the first mold core monomer 120 is provided with a first positioning groove 121, the second mold core monomer 130 is provided with a second positioning groove 131 and a positioning column 132 located in the second positioning groove 131, and the second mold core body 200 is provided with a mold groove 221 and a positioning cavity 231; the first positioning groove 121 and the mold groove 221 cooperate to form a first molding chamber 400, the second positioning groove 131 and the positioning cavity 231 are docked and matched, the positioning column 132 is inserted into the positioning cavity 231, and there is a gap between the side wall of the positioning column 132 and the side wall of the positioning cavity 231 to form a second molding chamber 500; wherein, a side surface of the fixed mold core part 210 facing the first mold core monomer 120 and a side surface facing each other on the first movable mold core part 220 and the second movable mold core part 230 cooperate to form the mold groove 221, and the positioning cavity 231 is provided on a side surface of the second movable mold core part 230 facing the second mold core monomer 130.
[0079] Through the above structure, the first mold core unit 120, the second mold core unit 130, the fixed mold core part 210, the first movable mold core part 220 and the second movable mold core part 230 can be manufactured and processed separately, and the manufacturing process is flexible; separate and 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 first movable mold core part 220 can slide relative to the fixed mold core part 210 along the first direction, and the second movable mold core part 230 can slide relative to the fixed mold core part 210 along the second direction, and the first direction and the second direction are opposite. The design of the first movable mold core part 220 and the second movable mold core part 230 can be adjusted along different directions to facilitate film bonding 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 part 210, so as to adapt to the production of workpieces of different shapes and specifications.
[0080] In some embodiments, the orthographic projection of the first molding chamber 400 overlaps with the orthographic projection of the second movable mold core 230. Therefore, the spatial structure of the second movable mold core 230 is fully utilized, so that the second movable mold core 230 participates in the molding of 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 molded simultaneously on a set of molds, which is beneficial to reducing the volume of the mold assembly, thereby reducing the volume of the entire injection mold.
[0081] It should be noted that, in some embodiments of the present invention, the above-mentioned first mold core monomer 120, second mold core monomer 130, fixed mold core part 210, first movable mold core part 220 and second movable mold core part 230 are all multiple, and each first mold core monomer 120, each second mold core monomer 130, each fixed mold core part 210, each first movable mold core part 220 and each second movable mold core part 230 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, 48 groups of snap-fit assemblies can be produced, that is, 48 first workpieces AA and 48 second workpieces BB are produced. Of course, other numbers of groups of the mold core structure can also be set to produce 36 groups, 64 groups of snap-fit assemblies, etc., which are not limited here.
[0082] According to one embodiment of the present invention, referring to Figure 4 and Figure 7 The third cooling water channel 330 includes a third main channel 331, a first branch section 334 and a second branch section 335. The third main channel 331 is provided with a first diversion position 332 and a second diversion position 333. The first branch section 334 is connected to the first diversion position 332, and the second branch section 335 is connected to the second diversion position 333. The first branch section 334 and the second branch section 335 are arranged side by side, and the first branch section 334 and the second branch section 335 are arranged corresponding to the mold groove 221.
[0083] It can be understood that in this embodiment, by setting two branch sections side by side and corresponding to the position of the mold groove 221, the cooling area can be increased, and the cooling water can be more in contact with the parts that need cooling, thereby improving the heat transfer efficiency and thus improving the cooling effect. The setting of the diversion position can control the flow path of the cooling water in the third main channel 331, so that it can smoothly enter the first branch section 334 and the second branch section 335, thereby achieving a uniform cooling effect.
[0084] According to one embodiment of the present invention, referring to Figure 4 and Figure 7 The fifth cooling water channel 350 includes two third cooling sections 351 connected in sequence. The two third cooling sections 351 are distributed on both sides of the mold cavity 231 , and the two third cooling sections 351 are both arranged along the axial direction of the mold cavity 231 .
[0085] It can be understood that in this embodiment, by distributing the two third cooling sections 351 on both sides of the mold cavity 231 and arranging them in the axial direction, it can be ensured that the temperature distribution in the entire mold cavity 231 is more uniform, thereby achieving comprehensive cooling coverage. This design can effectively reduce the temperature of the mold cavity 231, prevent the occurrence of problems such as thermal stress and deformation, and improve production efficiency and quality stability. The two third cooling sections 351 can be independently set and controlled to perform different cooling treatments on different parts of the mold cavity 231. At the same time, independently setting and controlling the two third cooling sections 351 can also improve the reliability of the system. If a problem occurs in one cooling section, the other cooling section can still work normally, thereby ensuring the normal operation of the system and the stability of product quality.
[0086] According to one embodiment of the present invention, referring to Figure 1 As shown, the positions where the first mold core body 100 and the second mold core body 200 are connected to the cooling pipeline 300 are both provided with installation grooves 600, and sealing rings 610 are installed at the installation grooves 600.
[0087] It is understandable that, in this embodiment, the role of the sealing ring 610 is to fill the tiny gap at the connection part to prevent liquid or gas leakage. The installation groove 600 provides a fixed position and support for the sealing ring 610, so that it can better play a sealing role. By setting the installation groove 600 at the connection position, a stable connection can be formed between the cooling pipeline 300 and the mold body. In addition, installing the sealing ring 610 at the installation groove 600 can play a sealing role, effectively preventing cooling water from leaking from the connection, and ensuring the normal operation of the cooling system.
[0088] In an optional embodiment, the sealing ring 610 is an annular rubber seal with good elasticity and wear resistance, which can adapt to different deformations and pressure changes and form a tight seal at the connection part.
[0089] Another embodiment of the present invention provides a production equipment for automobile parts production, including any of the above-mentioned injection molds for automobile parts production.
