Technical Field

[0001] This utility model relates to the field of molds, specifically to a mold for processing high-flatness energy storage bases. Background Technology

[0002] Energy storage bases are specifically a part of high-voltage energy storage products. Because they need to be used in high-voltage products, energy storage bases require high-voltage resistance. Current technology uses PPS material as the raw material for energy storage bases. However, in the actual injection molding process, the finished energy storage bases have the following defects: 1. They are prone to edge warping; 2. Secondary crystallization occurs. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is how to solve the problems generated during the injection molding process. To this end, a mold for processing a high-flatness energy storage base includes:

[0006] The glue inlets are arranged in two rows in a first direction, which is along the long sidewall of the energy storage base.

[0007] The glue inlet includes a first glue inlet and a second glue inlet. The first glue inlet forms a row, and the second glue inlet forms a row. The distance from the first glue inlet to the long side wall of the energy storage base is L1, and the distance from the second glue inlet to the long side wall of the energy storage base is L2. L1 and L2 are not equal.

[0008] The values ​​of L1 and L2 were obtained through simulation using Moldex3D software.

[0009] The glue inlet includes a first glue inlet and a second glue inlet. The first glue inlet forms a row, and the second glue inlet forms a row. The diameters of the first glue inlet and the second glue inlet are different.

[0010] This utility model provides a mold for processing high-flatness energy storage bases. The different diameters of the molds allow for different amounts of adhesive to be injected into different areas of the energy storage base, resulting in a stable filling effect.

[0036] Example 1

[0037] This embodiment provides a mold for processing high-flatness energy storage bases, as shown in the attached figure. Figures 1-7 As shown, it includes:

[0038] Cavity 100 is used to form energy storage base 11. Specifically, cavity 100 is formed by the cooperation of fixed mold and moving mold 16. When the structure of energy storage base 11 is constant, those skilled in the art should know the structure corresponding to cavity 100, so it will not be described in detail here.

[0039] The system has several sprues, arranged in at least two rows with at least two sprues per row, for a total of at least four sprues. These sprues are arranged in an array, but can also be distributed according to actual needs. All sprues are connected to the top of the cavity 100. Here, the sprues are top-mounted. Using multiple sprues ensures even injection, preventing edge warping and secondary crystallization, thus improving the flatness of the molded energy storage base 11.

[0040] Specifically, as shown in the attached document Figures 1-4As shown, the glue inlets are distributed in two rows along the long sidewall of the energy storage base 11 in a first direction. This two-row arrangement allows for precise control of the glue inlet amount at each inlet, improving flatness. In this embodiment, four glue inlets are used per row, for a total of eight inlets across two rows, providing eight glue inlet positions. Those skilled in the art can adjust the number of inlets according to actual needs. Alternatively, it can be configured with three or four rows.

[0041] Specifically, as shown in the attached document Figures 1-4 As shown, the glue inlet includes a first glue inlet 12 and a second glue inlet 13. The first glue inlets 12 form a row, and the second glue inlets 13 form a row. There are four first glue inlets 12 and four second glue inlets 13. The four first glue inlets 12 and the four second glue inlets 13 are equally spaced. The distance L1 between the first glue inlet 12 and the long side wall of the energy storage base 11 is the same as the distance between the first glue inlet 12 and the nearest long side wall of the energy storage base 11. Specifically, L1 is the distance from the first glue inlet 12 to the rear long side wall of the energy storage base 11. The distance L2 between the second glue inlet 13 and the long side wall of the energy storage base 11 is the same as the distance between the second glue inlet 13 and the nearest long side wall of the energy storage base 11. Specifically, L2 is the distance from the second glue inlet 13 to the front long side wall of the energy storage base 11. L1 and L2 are not equal. The values ​​of L1 and L2 can be adjusted according to actual needs. The limitation of the first glue inlet 12 and the second glue inlet 13 satisfies the glue inlet amount in different areas of the energy storage base 11, forming a stable filling effect.

[0042] Specifically, the values ​​of L1 and L2 are obtained through simulation using Moldex3D software. Simulation with Moldex3D software allows for more accurate determination of these values. Compared to manual adjustment based on experience, the software can obtain values ​​faster and more precisely to achieve the desired injection molding effect.

[0043] Specifically, as shown in the attached document Figures 1-4 As shown, the glue inlet includes a first glue inlet 12 and a second glue inlet 13. The first glue inlets 12 form a row, and the second glue inlets 13 form a row. Here, there are four first glue inlets 12 and four second glue inlets 13. The four first glue inlets 12 and the four second glue inlets 13 are equally spaced. The diameters of the first glue inlets 12 and the second glue inlets 13 are different. The difference in diameter allows for different glue inlet amounts in different areas of the energy storage base 11, creating a stable filling effect. Here, the diameters of the first glue inlets 12 and the second glue inlets 13 can be simulated using Moldex3D software or set based on manual experience.

[0044] Specifically, as shown in the attached document Figures 1-6As shown, it also includes an elastic clamping member 14 and a first insert 15. The inner wall of the energy storage base 11 is provided with a fixing post 111, which has a downward-opening fixing cavity 112. During injection molding, the cavity 100 forms the fixing post 111. The first insert 15 engages with the upper end of the elastic clamping member 14, extending into the cavity 100 to form the fixing cavity 112. Here, the outer wall of the first insert 15 engages with the colloid to form the inner wall of the fixing cavity 112. The top end of the elastic clamping member 14 forms the bottom surface of the fixing cavity 112. The first insert 15 and the elastic clamping member 14 work together to create an elastic fixation effect, making the fixed cavity 112 more stable after injection molding.

[0045] Specifically, there are two elastic clamping members 14, which are located on both sides of the first insert 15. The two elastic clamping members 14 are distributed on the left and right sides to achieve a better clamping and fixing effect, and the fixing post 111 is less likely to deform during demolding.

[0046] Specifically, as shown in the attached document Figure 7 As shown, it also includes a moving mold 16, which has circulating water channels 161 distributed on the outside of the cavity 100. The circulating water channels 161 create an enveloping effect, achieving better cooling and ensuring a more even temperature distribution in each area. Here, the circulating water channels 161 have a rectangular structure. In addition, the fixed mold can also be equipped with corresponding water channels to achieve cooling.

[0047] Specifically, in addition to these, there are other inserts that work together to form the sidewalls of cavity 100.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
