[0040] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0041] like Figure 1 As shown, an injection mold 10 in one embodiment includes a cell support forming mechanism 10a, and the injection mold 10 also includes a front mold base 10b and a rear mold base 10c.

[0042] like Figures 1 to 3a As shown, in one embodiment, the cell support forming mechanism 10a includes a die 100, a separating component 200, a punch fixing component 300 and a plurality of punch components 400, wherein the die 100 has a forming groove 110, and the separating component 200 is detachably connected to the forming groove 110 to divide the forming groove 110 into a plurality of current forming areas 111.

[0043] like Figures 2a to 3aAs shown, the punch fixing member 300 has a forming surface 310, and several punch assemblies 400 are detachably connected to the forming surface 310. When the mold is closed, the punch assemblies 400 are respectively housed in several current forming areas 111. Each punch assembly 400 includes multiple spaced circular punches 410. Each circular punch 410 is detachably connected to the forming surface 310 and abuts against the inner wall of the forming groove 110. The multiple circular punches 410 of each punch assembly 400, the forming surface 310, and the inner wall of the corresponding current forming area 111 together form a forming cavity. Each forming cavity is used to form the battery cell bracket 20. The separator 200 fits against the forming surface 310 when the mold is closed to prevent adjacent forming cavities from connecting, so that each forming cavity is formed independently.

[0044] It is understood that the die 100 has a plurality of feed hole groups, which are connected to a plurality of molding cavities one by one. Each feed hole group includes at least one feed through hole, and each feed through hole is connected to the corresponding molding cavity. In this embodiment, when injection molding is performed, the molten plastic fills each molding cavity, and each molding cavity forms a cell support 20 after cooling and molding.

[0045] The aforementioned injection mold 10 and battery cell bracket forming mechanism 10a, each circular punch 410 is used to form the mounting holes of the battery cell bracket 20. By changing the circular punches 410 with different outer diameters, the mounting hole size of the battery cell bracket 20 can be changed. By adjusting the position of the separating component 200 in the forming groove 110, different sizes of the current forming area 111 can be divided. Combined with adjusting the arrangement of the multiple circular punches 410 of each punch component 400, the outer contour size, number of mounting holes, and arrangement of mounting holes of the battery cell bracket 20 formed in each forming cavity can be adjusted. In summary, by adjusting the outer diameter of each circular punch 410, adjusting the position of the separating component 200, and adjusting the arrangement of the multiple circular punches 410 of each punch component 400, the injection mold 10 can be used to produce battery cell brackets 20 of different specifications. This makes the injection mold 10 usable for producing battery cell brackets 20 of multiple specifications, improving the versatility of the injection mold 10, avoiding the need to use multiple injection molds 10 for production, and reducing production costs. like Figure 1 As shown, in one embodiment, the die 100 is fixedly connected to the front die base 10b, and the punch fixing member 300 is embedded in the rear die base 10c.

[0046] like Figure 2bAs shown, in one embodiment, there are four current forming areas 111: a first current forming area 111a, a second current forming area 111b, a third current forming area 111c, a fourth current forming area 111d, and a fifth current forming area 111e. In another embodiment, there are multiple forming cavities, allowing the cell bracket forming mechanism 10a to produce multiple cell brackets 20 in a single molding process, thus improving the production efficiency of the injection mold 10.

[0047] In one embodiment, multiple molding cavities are used to mold at least two sizes of cell brackets 20, so that the injection mold 10 can produce at least two sizes of cell brackets 20 in one molding process.

[0048] like Figure 3a and Figure 3b As shown, in one embodiment, a plurality of circular punches 410 in at least one punch assembly 400 are arranged in multiple rows and columns, such that the injection mold 10 can obtain at least one cell support 20 with multiple rows and columns of mounting holes in one molding process, such as a cell support 20 with 2 rows and 3 columns of mounting holes or a cell support 20 with 2 rows and 2 columns of mounting holes.

[0049] like Figure 3a and Figure 3b As shown, in one embodiment, a plurality of circular punches 410 in at least one punch assembly 400 are arranged in a single row or a single column, such that the injection mold 10 can obtain at least one cell support 20 with a single row or a single column of mounting holes in one molding process, for example, a cell support 20 with 4 mounting holes in 1 row or a cell support 20 with 4 mounting holes in 1 column.

[0050] like Figure 2a As shown, in one embodiment, the separating component 200 includes multiple separating strips 210, all of which are detachably connected to the molding groove 110 to divide the molding groove 110 into several current molding areas 111. In this embodiment, by adjusting the position of each separating strip 210 in the molding groove 110, the molding groove 110 is divided into several current molding areas 111. Since the multiple separating strips 210 form a separating component, the shape variation of the separating component 200 is increased, allowing the molding groove 110 to be divided into more specifications of current molding areas 111 by the separating component 200, thereby enabling the injection mold 10 to produce more specifications of battery cell brackets 20.

[0051] like Figure 2b As shown, in one embodiment, the plurality of separators 210 are respectively a first separator 211, a second separator 212, a third separator 213, a fourth separator 214, a fifth separator 215, a sixth separator 216, and a seventh separator 217. Figure 2dAs shown, in one embodiment, the molding groove 110 includes a plurality of reserved molding areas 112 connected sequentially along a first direction, and each reserved molding area 112 includes a plurality of molding partitions 1121 connected sequentially along a second direction, wherein the first direction is...

In one embodiment, the angle between the first direction and the second direction is 90 degrees. Of course, in other embodiments, the angle between the first direction and the second direction is an obtuse angle or an acute angle.

Figure 3c The direction pointed to by arrow A in the diagram, the second direction is Figure 3c In the direction indicated by arrow B, the plurality of circular punches 410 of each punch assembly 400 are detachably connected to a plurality of continuously arranged fixed partitions 3111, so that the plurality of circular punches 410 of each punch assembly 400 are accommodated within the corresponding current forming area 111 during mold closing. In one embodiment, the angle between the first direction and the second direction is 90 degrees. Of course, in other embodiments, the angle between the first direction and the second direction can also be an obtuse angle or an acute angle.

[0053] like Figure 3b As shown, in one embodiment, the number of punch assemblies 400 is five.

[0054] like Figure 2c and Figure 2d In one embodiment, the die 100 has a first threaded hole 101 on each forming section 1121, and the separator 200 has a plurality of first clearance holes 201, which are connected one-to-one with the first threaded holes 101 on the corresponding forming sections 1121. The cell support forming mechanism 10a also includes a plurality of first fasteners 500, which are correspondingly inserted into the plurality of first clearance holes 201. The first end of each first fastener 500 abuts against the separator 200, and the second end of each first fastener 500 is threaded into the corresponding first threaded hole 101, so that the separator 200 is detachably connected to the corresponding forming sections 1121 through the plurality of first fasteners 500.

[0055] like Figure 3b and Figure 4As shown, in one embodiment, the forming surface 310 also has limiting holes 312 on each fixed partition 3111, and each circular punch 410 has a protruding embedded part 411. The embedded part 411 of each circular punch 410 is embedded in the limiting hole 312, so that the inner wall of each limiting hole 312 limits the corresponding circular punch 410, ensuring the positional stability of the circular punch 410, and thus ensuring the accuracy of the cell support 20.

[0056] like Figure 3b In one embodiment, the forming surface 310 has a second threaded hole 313 on the inner wall of each limiting hole 312, and each circular punch 410 also has a second clearance hole 412. The battery cell bracket forming mechanism 10a also includes a plurality of second fasteners 600, which are respectively inserted into the second clearance holes 412 of the plurality of circular punches 410. The first end of each second fastener 600 abuts against the corresponding circular punch 410, and the second end of each second fastener 600 is threaded into the corresponding second threaded hole 313, so that each circular punch 410 is detachably connected to the corresponding fixed partition 3111 through the corresponding second fastener 600.

[0057] like Figure 2c and Figure 2d As shown, in one embodiment, the die 100 has a plurality of positioning components 120 protruding from the inner wall of the forming groove 110 and spaced apart along a first direction. Each positioning component 120 includes arc-shaped positioning posts 121 spaced apart along a second direction. The first direction is... Figure 2d The direction pointed to by arrow A in the diagram, the second direction is Figure 2d The direction indicated by arrow B is perpendicular to the second direction. The diameters of the multiple arc-shaped positioning posts 121 are equal. Each forming section 1121 is surrounded by four spaced arc-shaped positioning posts 121. Each arc-shaped positioning post 121 is cylindrical and offset from the inner wall of the forming groove 110. The arc-shaped positioning post 121 connected to the inner wall of the forming groove 110 is semi-circular.

[0058] like Figure 2c and Figure 2dAs shown, each separator 210 is further detachably embedded within a plurality of continuously arranged molding sections 1121 to seal the corresponding plurality of continuously arranged molding sections 1121, thereby dividing the molding groove 110 into several current molding areas 111. Each separator 210 has a plurality of spaced semicircular notches along its circumference, and the diameter of each semicircular notch of each separator 210 is equal to the diameter of each arc-shaped positioning post 121. After each separator 210 is connected to the molding groove 110, the inner walls of the plurality of semicircular notches of each separator 210 are correspondingly attached to the plurality of arc-shaped positioning posts 121. In this embodiment, the installation efficiency of each separator 210 is improved by positioning each separator 210 with multiple arc-shaped positioning posts 121, thereby improving the efficiency of changeover production of the injection mold 10.

[0059] Furthermore, the two ends of each arc-shaped positioning post 121 are connected to the inner wall of the forming groove 110 and the forming surface 310 respectively, so that each arc-shaped positioning post 121 is inserted into the corresponding forming cavity and forms a through hole for the cell bracket 20. The through hole is used to avoid the threaded fasteners so that the cell bracket 20 can be installed into the outer shell of the battery module through multiple threaded fasteners.

[0060] like Figure 2c As shown, in one embodiment, each separator 210 includes a plurality of separator units connected in sequence. The plurality of separator units of each separator 210 are embedded in the corresponding plurality of molding partitions 1121 to seal the corresponding plurality of fixed partitions 3111, thereby dividing the molding groove 110 into a plurality of current molding areas 111.

[0061] Compared with the prior art, the present invention has at least the following advantages:

[0062] Each circular punch 410 is used to form the mounting holes of the battery cell bracket 20. By changing the circular punches 410 with different outer diameters, the mounting hole size of the battery cell bracket 20 can be changed. By adjusting the position of the separating component 200 in the forming groove 110, different sizes of the current forming area 111 can be divided. In addition, by adjusting the arrangement of the multiple circular punches 410 of each punch component 400, the outer contour size, number of mounting holes, and arrangement of mounting holes of the battery cell bracket 20 formed in each forming cavity can be adjusted. In summary, by adjusting the outer diameter of each circular punch 410, adjusting the position of the separating component 200, and adjusting the arrangement of the multiple circular punches 410 of each punch component 400, the injection mold 10 can be used to produce battery cell brackets 20 of different specifications.
