The battery pack mold is a special tool used in the battery pack manufacturing process to shape, position and fix the external structure of the battery pack. It is an indispensable part of the battery pack production line. Its design and manufacturing quality directly determine the structural accuracy, performance and production efficiency of the battery pack.

[0003] In the existing technology, such as the document with publication number CN220259241U, a new energy battery pack shell stamping die is specifically disclosed. Although the document can lift up the molded battery pack shell pasted in the die groove through multiple top blocks, so that the sticking part between the battery pack shell and the die groove can be separated in time, the molded battery pack shell will be embedded in the lower mold under pressure and fully fit with the inner wall of the lower mold. The top block in the device of this document is fixedly installed on the top of the top rod, and the top cover is fixedly installed on the supporting cross frame, so that the top block is relatively stable during the rising process. At this time, it is difficult to demold only by the spring rebound force, and the demolding effect is not good. For this reason, we propose an anti-deformation thin-wall shell battery pack mold.

[0025] like Figure 6 As shown, the telescopic assembly includes a mounting sleeve 18, and slide grooves 19 are respectively provided at both ends of the mounting sleeve 18.

The circumferential outer walls of the two connecting rods 21 are fixedly connected with second limiting sleeves 24, the inner ends of the second springs 22 are connected and fixed to the fixed sleeves 20, and the outer ends of the second springs 22 are connected and fixed to the abutting rods 23. The bottom of the bottom mold 1 is fixedly connected with a support frame 9, and the inner wall of the support frame 9 is fixedly connected with a fixed plate 10, and the inner wall of the fixed plate 10 is fixedly connected with an electric push rod 11, and the output end of the electric push rod 11 is fixedly connected to the support rod 14. When the connecting sleeve 13 moves upward, the ends of the abutting rods 23 at both ends of the installing sleeve 18 are respectively squeezed with the inner ends of multiple limit rods 17. At this time, the first spring 16 is compressed, and the abutting rod 23 pushes the connecting rod 21 to slide along the inner wall of the fixing sleeve 20. The second spring 22 is compressed, and when the abutting rod 23 retracts inward, the abutting rod 23 is separated from the contact with the limit rod 17.

When the connecting sleeve 13 moves upward, the ends of the abutting rods 23 at both ends of the mounting sleeve 18 are respectively squeezed with the inner ends of multiple limit rods 17. At this time, the first spring 16 is compressed, and the abutting rod 23 pushes the connecting rod 21 to slide along the inner wall of the fixing sleeve 20. The second spring 22 is compressed, and the abutting rod 23 retracts inward. At this time, the abutting rod 23 is separated from the contact with the limit rod 17.
