[0001] This application claims the priority of the invention patent application with the application number

[0002] 202311848651.1, titled "Forming Process, Housing and Extrusion Die", filed with the China National Intellectual Property Administration on December 28, 2023, the entire content of which is incorporated herein by reference. Technical Field

[0003] This application relates to the field of thermal management technology, and particularly to a forming process, a housing and an extrusion die. Background Art

[0004] The accumulator and the gas-liquid separator are important components in the thermal management system. Most traditional accumulators and gas-liquid separators are cylindrical. However, with the development of integrated components, more and more components tend to be integrally installed together, and thus, the special-shaped accumulators and gas-liquid separators will be more widely used. The special-shaped accumulator includes a partition board and a liquid storage tank. The partition board can be separately manufactured and then welded or fixed to the liquid storage tank by other means, but this production process has many steps and is time-consuming.

[0005] In the related art, the partition board and the liquid storage tank are integrally formed by extrusion. However, in the current forming method of the partition board and the liquid storage tank, cracks will occur at the bottom of the liquid storage tank during extrusion, which affects the product qualification rate. Summary of the Invention

[0006] The purpose of this application is to provide a forming process, a housing and an extrusion die, which can improve the qualification rate of products.

[0007] To achieve the above purpose, an embodiment of this application adopts the following technical solutions:

[0008] A forming process includes the following steps:

[0009] Provide a matching moving die and bottom die;

[0010] The first forming part and the second forming part are closed to form a cavity;

[0011] The moving die moves towards the bottom die to extrude the material located in the cavity.

[0012] According to another aspect of this application, this application further provides a housing, including a frame, a partition board assembly and a protruding part. The frame has a receiving cavity; at least part of the partition board assembly is located in the receiving cavity, and the protruding part protrudes from the frame in a direction away from the partition board assembly.

[0013] In an embodiment of the present application, the convex portion protrudes from the frame in a direction away from the partition assembly. This is beneficial to enhancing the strength of the bottom surface of the housing and can alleviate the phenomenon of cracks generated at the bottom of the housing when the moving mold extrudes the material.

[0014] According to another aspect of the present application, the present application further provides an extrusion mold, which includes a moving mold, a bottom mold, and a housing. The moving mold can move relative to the bottom mold. The moving mold has a gap, and the bottom mold has a recess, and the recess is correspondingly arranged with the gap.

[0015] In an embodiment of the present application, the recess is located in the bottom mold, the gap is located in the moving mold, and the recess and the gap are correspondingly arranged. When the extrusion mold extrudes the material to form the housing, the material needs to overcome the resistance of material deformation during the extrusion process, and the improvement effect on the crack phenomenon is increased.

[0016] A molding process includes the following steps:

[0017] Provide an extrusion mold, which includes a moving mold and a bottom mold;

[0018] Place the material to be processed between the moving mold and the bottom mold, and start the extrusion mold to extrude the material to form a housing blank;

[0019] Milling and removing the convex portion located outside the housing.

[0020] In an embodiment provided by the present application, the extrusion mold extrudes the material placed between the moving mold and the bottom mold to form a housing, and then the convex portion located outside the housing is removed by milling. Description of the Drawings

[0034] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings. A lot of specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] The following further illustrates the present application with reference to the accompanying drawings and specific embodiments:

[0036] Figure 1 Schematically shows a molding process, including the following steps:

[0037] Provide a matching moving die 41 and bottom die 51;

[0038] The moving die 41 cooperates with the bottom die 51 to extrude the material, and the gap 411 forms the partition assembly 20, and the recess 511 forms the protruding portion 30 opposite to the partition assembly 20.

[0039] In this embodiment, the gap 411 can form the partition assembly 20, and the recess 511 can form the protruding portion 30 opposite to the partition assembly 20, so that the formed housing 100 can form the partition assembly 20 and the protruding portion 30 opposite to the partition assembly 20. This is beneficial to enhancing the bottom surface strength of the housing 100 and can reduce the phenomenon of cracks generated at the bottom during the molding of the housing 100.

[0040] A molding process, including the following steps:

[0041] Provide an extrusion mold, the extrusion mold includes a moving die 41 and a bottom die 51;

[0042] Place the material to be processed between the moving die 41 and the bottom die 51, and start the extrusion mold to extrude the material to form a housing blank;

[0043] Milling to remove the protruding portion 30 located outside the housing.

[0044] In an embodiment provided by the present application, the extrusion mold extrudes the material placed between the moving die 41 and the bottom die 51 to form a housing, and then the protruding portion 30 located outside the housing is removed by milling.

[0045] Specifically, the molding process further includes the following steps:

[0046] The first molding part 60 and the second molding part 70 are closed to form a cavity 72;

[0047] The moving die 41 moves towards the bottom die 51 to extrude the material located in the cavity 72.

[0048] In the step where the first forming part 60 and the second forming part 70 are closed to form the cavity 72, a first driving assembly (not shown in the figure) drives the first mold base 42 to move towards the second mold base 52, so that the first forming part 60 and the second forming part 70 are in contact with each other;

[0049] In the step where the moving mold 41 moves towards the bottom mold 51 to extrude the material located in the cavity 72, when the first forming part 60 and the second forming part 70 are in contact with each other, the first driving assembly continues to drive the first mold base 42 to move towards the second mold base 52, so that the moving mold 41 moves towards the bottom mold 51 and extrudes the material located in the cavity 72.

[0050] In this embodiment, the first driving assembly drives the first mold base 42 to move towards the second mold base 52, so that the first forming part 60 and the second forming part 70 are in contact with each other; when the first forming part 60 and the second forming part 70 are in contact with each other, the first driving assembly continues to drive the first mold base 42 to move towards the second mold base 52, so that the moving mold 41 moves towards the bottom mold 51 and extrudes the material located in the cavity 72.

[0051] Specifically, in this embodiment, the first driving assembly drives the first mold base 42 to move towards the second mold base 52. When the first forming part 60 and the second forming part 70 are in contact with each other, the first cavity 61 and the second cavity 71 are closed to form the cavity 72. It should be noted that in this embodiment, the gap 411 can form the partition assembly 20, the recess 511 can form the protrusion 30 opposite to the partition assembly 20. When the first driving member drives the moving mold 41 to move towards the bottom mold 51, and the moving mold 41 and the bottom mold 51 cooperate to gradually extrude the material located in the cavity 72, the surface of the housing 100 can form the protrusion 30 opposite to the partition assembly 20. This is beneficial to enhancing the strength of the bottom surface of the housing 100 and can reduce the phenomenon of cracks generated at the bottom during the molding of the housing 100.

[0052] In this embodiment, the material is put into the second cavity 71 through the feeding mechanism or manual operation. It should be noted that at this time, the material is a solid aluminum blank, and the solid aluminum blank can be put into the second cavity 71 through manual or feeding mechanism for subsequent extrusion processing.

[0053] The forming process further includes the following steps:

[0054] The first driving assembly drives the first mold base 42 away from the second mold base 52, so that the first forming part 60 and the second forming part 70 are separated;

[0055] When the first forming part 60 is separated from the second forming part 70, the first driving component continues to drive the first die base 42 to move away from the second die base 52, so that the moving die 41 moves away from the bottom die 51 to switch to the mold opening state;

[0056] A second driving component (not shown in the figure) drives the bottom die 51 to move towards the moving die 41 to eject the housing 100.

[0057] It should be noted that the first driving component can drive the first die base 42 to move upward away from the second die base 52. When the first forming part 60 is separated from the second forming part 70, the first driving component continues to drive the first die base 42 to move away from the second die base 52, so that the moving die 41 moves away from the bottom die 51 to switch to the mold opening state. In the mold opening state, the second driving component drives the bottom die 51 to move towards the moving die 41 to eject the formed housing 100.

[0058] The forming process further includes the following steps:

[0059] The convex part 30 of the housing 100 is removed by a cutting mechanism, and the housing 100 is processed into a liquid storage tank.

[0060] It should be explained that the housing 100 is integrally formed by cold extrusion. Since the wall thickness of the housing 100 is relatively thin, cracks will occur when extruding the bottom of the liquid storage tank corresponding to the partition plate assembly 20, and the maximum depth can reach 7 mm. In this way, at least 7 mm of milling is required to obtain a smooth and flat plane for the qualified product bottom. In the related art, at least 7 mm of allowance is added at the bottom when designing the blank to improve the qualified rate of the product. For mass production, such a large processing allowance not only wastes materials, but also wastes processing time and affects the production efficiency of the product.

[0061] Furthermore, the depth of the concave part 511 can be determined by obtaining the crack depths of different housings 100. The average depth of the cracks is n mm and the maximum depth is m mm. The improved depth of the concave part 511 is H mm. It is judged whether the depth H of the concave part 511 satisfies H≥m>n. If the depth H of the concave part 511 does not satisfy the above conditions with the average depth n mm and the maximum depth m mm of the cracks, the depth H of the concave part 511 is adjusted until the above conditions are satisfied. In this way, the convex part 30 can obtain an optimal height, which can reduce the waste of raw materials and optimize the cost.

[0062] In this embodiment, according to this process method, the position of the recess 511 is determined by first determining the position of the formed partition assembly 20, and the structures of the moving die 41 and the bottom die 51 are adapted according to the structure and position of the recess 511, so that the housing 100 manufactured by the extrusion die can have a protrusion 30 that can be further improved by milling. On the one hand, this is beneficial to enhancing the strength of the bottom surface of the housing 100, and on the other hand, it can alleviate the phenomenon of cracks generated at the bottom of the housing 100 when the moving die 41 extrudes the material. It can be understood that this process method can not only produce the housing 100, but also produce other partitioned containers formed by cold extrusion. Therefore, if this method is used to produce containers, they all fall within the protection scope of this application.

[0063] Combined with Figures 2 to 4 As shown, according to another aspect of the present application, the present application further provides a housing 100. The housing 100 includes a frame 10, a partition assembly 20, and a protrusion 30. The frame 10 has a receiving cavity 11, and at least a part of the partition assembly 20 is located in the receiving cavity 11 and divides the receiving cavity 11 into at least a liquid storage cavity and a circulation cavity; the protrusion 30 protrudes from the frame 10 in a direction away from the partition assembly 20. Specifically, the protrusion 30 protrudes in a direction away from the partition assembly 20, and the protrusion 30 is disposed opposite to the partition assembly 20. In this way, it is beneficial to enhancing the strength of the bottom surface of the housing 100 and can reduce the cracks generated during the forming process of the housing 100. It should be noted that the protrusion 30 needs to be cut off after the housing 100 is formed to become a liquid storage tank. Please refer specifically to FIG. Figure 3 , the partition assembly 20 includes a first partition 21 and a second partition 22, and the first partition 21 intersects with the second partition 22; the protrusion 30 includes a first reinforcing member 31 and a second reinforcing member 32, the first reinforcing member 31 intersects with the second reinforcing member 32, the first reinforcing member 31 is disposed opposite to the first partition 21, and the second reinforcing member 32 is disposed opposite to the second partition 22.

[0064] In this embodiment, the number of the second partition 22 and the second reinforcing member 32 is at least one. The length direction of the housing 100 is as Figure 3 shown in the X direction in Figure 3 , and both the first partition 21 and the first reinforcing member 31 are arranged along the length direction of the housing 100; the width direction of the housing 100 is as Figure 3As shown in the Z direction. Along the height direction of the housing 100, the first partition 21 and the first reinforcing member 31 are located on both sides of the frame 10, that is, the first partition 21 is located in the accommodating cavity 11, and the first reinforcing member 31 is located on the side of the bottom of the frame 10 away from the first partition 21; the second partition 22 and the second reinforcing member 32 are located on both sides of the frame 10, that is, the second partition 22 is located in the accommodating cavity 11, and the second reinforcing member 32 is located on the side of the bottom of the frame 10 away from the second partition 22.

[0065] The terms "first", "second", "third", and "fourth" in this specification are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0066] It should be noted that the orientation words such as up, down, left, right, front, and back mentioned in this specification are based on the orientation in the accompanying drawings of the specification. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on this application.

[0067] The partition assembly 20 further includes a third partition 23 and a fourth partition 24. The third partition 23 intersects with the second partition 22, the third partition 23 intersects with the fourth partition 24, and one end of the fourth partition 24 away from the third partition 23 is connected to the inner wall of the frame 10; the convex portion 30 further includes a third reinforcing member 33 and a fourth reinforcing member 34. The fourth reinforcing member 34 intersects with the third reinforcing member 33, the third reinforcing member 33 is disposed opposite to the third partition 23, and the fourth reinforcing member 34 is disposed opposite to the fourth partition 24. It should be noted that along the third direction, the third partition 23 and the third reinforcing member 33 are located on both sides of the bottom of the frame 10. The third partition 23 is located in the accommodating cavity 11, and the third reinforcing member 33 is located on the side of the bottom of the frame 10 away from the third partition 23, and both the third partition 23 and the third reinforcing member 33 are arranged along the first direction; along the third direction, the fourth partition 24 and the fourth reinforcing member 34 are located on both sides of the bottom of the frame 10.

The wall forming the third flow-through cavity 113 includes a third flow-through wall surface 1131, and the third flow-through wall surface 1131 has a third flow-through port 1132. The fourth flow-through cavity 114 is communicated with the third flow-through port 1132 and the liquid outlet 13. It should be noted that the liquid inlet 12 is located in the first flow-through cavity 111. The refrigerant enters the first flow-through cavity 111 from the liquid inlet 12. The refrigerant in the first flow-through cavity 111 inputs the refrigerant into the second flow-through cavity 112 through the first flow-through port 1112. Then, the refrigerant input into the second flow-through cavity 112 inputs the refrigerant into the third flow-through cavity 113 through the second flow-through port 1122. The refrigerant input into the third flow-through cavity 113 inputs the refrigerant into the fourth flow-through cavity 114 through the third flow-through port 1132. Since the liquid outlet 13 is located in the fourth flow-through cavity 114, the refrigerant in the fourth flow-through cavity 114 can flow out at the liquid outlet 13.

[0069] Specifically, the liquid storage cavity includes a first liquid storage cavity 115, a second liquid storage cavity 116, a third liquid storage cavity 117, and a fourth liquid storage cavity 118.

The first liquid storage cavity 115 communicates with the first flow cavity 111, and the fourth liquid storage cavity 118 communicates with the fourth flow cavity 114. The wall forming the first liquid storage cavity 115 includes a first liquid storage wall surface 1151, and the first liquid storage wall surface 1151 has a first through hole 1152.

It can be understood that the refrigerant enters the first flow cavity 111 from the liquid inlet 12. The refrigerant located in the first flow cavity 111 can input the refrigerant into the second flow cavity 112 through the first flow port 1112, and the refrigerant located in the first flow cavity 111 can also be input into the first liquid storage cavity 115, the second liquid storage cavity 116, the third liquid storage cavity 117, and the fourth liquid storage cavity 118. The refrigerant located in the first liquid storage cavity 115 can communicate with the second liquid storage cavity 116, and the refrigerant located in the first liquid storage cavity 115 can also communicate with the third flow cavity 113 through the first through hole 1152.

[0071] More specifically, along the height direction of the housing 100, the first flow port 1112 is located at the middle part of the third partition plate 23. The first flow port 1112 is located at the arc surface structure, and the arc surface plays a certain guiding role. Moreover, the second flow cavity 112 is located in the gravity direction of the first flow cavity 111, so that the refrigerant in the first flow cavity 111 can flow into the second flow cavity 112 better.

[0072] Along the height direction of the housing 100, the first through hole 1152 is located at the middle part of the first partition plate 21. The first through hole 1152 is located at the arc surface structure, and the arc surface plays a certain guiding role. Moreover, the third flow cavity 113 is located in the gravity direction of the first liquid storage cavity 115, so that the refrigerant in the first liquid storage cavity 115 can flow into the third flow cavity 113 better.

[0073] Along the height direction of the housing 100, the second through hole 1162 is located at the middle part of the first partition plate 21. The second through hole 1162 is located at the arc surface structure, and the arc surface plays a certain guiding role. Moreover, the fourth flow cavity 114 is located in the gravity direction of the second liquid storage cavity 116, so that the refrigerant in the second liquid storage cavity 116 can flow into the fourth flow cavity 114 better.

[0074] Along the height direction of the housing 100, the third through hole 1172 is located at the middle part of the first partition plate 21.

[0075] Combined Figures 5 to 10As shown, according to another aspect of the present application, the present application further provides an extrusion die, which includes a movable die 41 and a bottom die 51. The movable die 41 can move relative to the bottom die 51. The movable die 41 has a gap 411, and the bottom die 51 has a recess 511. The shape of the recess 511 is adapted to the shape of the gap 411. It should be noted that the movable die 41 can move relative to the bottom die 51 to extrude materials. During the extrusion process, the materials filled in the gap 411 will form the partition assembly 20, and the materials filled in the recess 511 will form the protrusion 30 of the housing 100. The design of the recess 511 enhances the strength of the bottom surface of the formed housing 100 and can alleviate the phenomenon of cracks generated at the bottom of the housing 100 when the movable die 41 extrudes materials.

[0076] Please refer specifically to Figures 6 to 8 , specifically, the extrusion die includes a first forming part 60 and a second forming part 70. The first forming part 60 can be separated from or in contact with the second forming part 70; the first forming part 60 has a first cavity 61, and the second forming part 70 has a second cavity 71 opposite to the first cavity 61. The extrusion die includes at least a closed die state and an open die state; in the closed die state, the first forming part 60 and the second forming part 70 are in contact with each other, and the first cavity 61 and the second cavity 71 are closed to form a cavity 72; in the open die state, the first forming part 60 and the second forming part 70 are separated from each other. It should be explained that after the first cavity 61 and the second cavity 71 are closed to form the cavity 72, the movable die 41 can move relative to the bottom die 51 to extrude the materials located in the cavity 72. After the housing 100 is extruded and formed, the first forming part 60 and the second forming part 70 are separated from each other, which is convenient for taking out the formed housing 100.

[0077] Please refer specifically to Figure 9 , the extrusion die includes a first driving component and a first die 40. The first die 40 includes a movable die 41, a first die base 42 and a first elastic member. The first driving component is drivingly connected to the first die base 42. One end of the movable die 41 is fixedly connected to or limitedly connected to or is an integral structure with the first die base 42. The other end of the movable die 41 is limitedly connected to the first forming part 60. At least part of the movable die 41 is located in the first cavity 61. The first elastic member is connected to the first die base 42 and the first forming part 60.

[0078] Please refer specifically to Figure 10, the extrusion die includes a second driving component and a second die 50. The second die 50 includes a bottom die 51, a second die base 52 and a second elastic member. One end of the bottom die 51 is drivingly connected to the second driving component, and the other end of the bottom die 51 is limit-connected to the second forming portion 70. At least a part of the bottom die 51 is located in the second cavity 71, and the second elastic member is connected to the second die base 52 and the second forming portion 70. In this embodiment, the first elastic member and the second elastic member are preferably but not limited to springs. Specifically, the first driving component is drivingly connected to the first die base 42 and is used to drive the first die base 42 to move in the direction towards the second forming portion 70. Since the moving die 41 is fixedly connected to the first die base 42, one end of the first elastic member is fixedly connected to the first die base 42, and the other end of the first elastic member is elastically connected to the first forming portion 60, so that the moving die 41 and the first forming portion 60 can be driven to move in the direction towards the second forming portion 70. When the first forming portion 60 abuts against the second forming portion 70, the first cavity 61 and the second cavity 71 are closed to form a cavity 72 for accommodating the material. At this time, the first forming portion 60 is subjected to an elastic force towards the second forming portion 70, and the second forming portion 70 is subjected to an elastic force towards the first forming portion 60, so that the first forming portion 60 and the second forming portion 70 can maintain elastic abutment with each other. On the basis that the first cavity 61 and the second cavity 71 are closed to form the cavity 72, the first driving component drives the moving die 41 to continue to move in the direction towards the bottom die 51, for extruding the material located in the cavity 72. During this period, the first forming portion 60 and the second forming portion 70 always maintain elastic abutment. After extrusion molding, the first driving component drives the first die base 42 to move in the direction away from the second forming portion 70. It can be understood that the moving die 41 is withdrawn from the cavity 72 under the drive of the first driving component. At this time, the first forming portion 60 still elastically abuts against the second forming portion 70. When the moving die 41 gradually moves away from the second forming portion 70, the first forming portion 60 moves away from the second forming portion 70 under the drive of the first driving member. At this time, the first forming portion 60 and the second forming portion 70 are separated from each other to open the cavity 72. After the moving die 41 and the first forming portion 60 move away from the second forming portion 70, the second driving component drives the bottom die 51 to move in the direction towards the moving die 41, so as to eject the formed housing 100, and the material taking is convenient.
