By installing hydraulic cylinders 10 at both ends of the lower die 9, the copper busbar stamping part can be lifted by the push rod driven by the hydraulic cylinders 10, and then the copper busbar stamping part can be taken out.

[0029] like Figure 3 and Figure 4As shown, an installation plate 5 is slidably connected to the outside of the upright 2. An installation groove 51 is provided in the middle of the installation plate 5. Sliding grooves 52 are provided at the upper and lower ends of the side wall of the installation groove 51. A positioning groove 54 is provided horizontally above the installation plate 5 and above the installation groove 51. Guide grooves 56 are provided on the side walls at both ends of the positioning groove 54. The inner wall of the guide groove 56 is slidably connected to the outer wall of the guide block 64, which can improve the stability of the L-shaped locking plate 63. A storage groove 55 is provided on the bottom side of both ends of the positioning groove 54. The storage groove 55 is located on both sides of the installation groove 51. An upper mold limiting structure 6 is installed in the positioning groove 54.

[0030] like Figure 2 , Figure 5 and Figure 6 As shown, the upper mold limiting structure 6 includes a rotating rod 61. One end of the rotating rod 61 is provided with a rotating head 65, which is embedded in a circular groove. The rotating rod 61 is set in the positioning groove 54 through a bearing. Both ends of the rotating rod 61 are provided with threaded sections 62. The outer walls of the threaded sections 62 are threaded with L-shaped locking plates 63. The lower outer wall of the L-shaped locking plates 63 is slidably connected to the receiving groove 55. The upper two outer walls of the L-shaped locking plates 63 are provided with guide blocks 64.

[0031] This utility model provides a copper busbar stamping die for new energy vehicles. The specific working principle is as follows: The workpiece material is placed in the lower die 9, and the upper die 7 is pressed against the lower die 9 by driving the cylinder 4. After the stamping is completed, the hydraulic cylinders 10 at both ends are driven to lift the copper busbar stamping part through the push rod. When it is necessary to disassemble, maintain or replace the upper die 7, the tool is inserted into the rotating head 65 and rotated to make the rotating rod 61 rotate, thereby causing the L-shaped locking plate 63 located on the threaded section 62 to move until the L-shaped locking plate 63 separates from the locking groove 81. The upper die 7 and the positioning block 8 are taken out by sliding extraction, which is convenient and quick to disassemble and assemble. After maintenance or replacement, the upper die 7 and the positioning block 8 are pushed in by insertion. The rotating head 65 is reversed to make the threaded section 62 reverse, thereby causing the L-shaped locking plates 63 at both ends to move towards the locking groove 81 until the L-shaped locking plates 63 are locked in the locking groove 81, thus completing the limiting of the upper die 7.
