[0026] The upper mold assembly 5 includes an upper mold 501. A guide post 502 is provided through the top of the upper mold 501. The guide posts 502 are symmetrically distributed about the horizontal center line of the upper mold 501. Several springs 503 are movably connected to the top of the upper mold 501. The springs 503 are distributed in a triangular shape.

[0027] The upper die 501 has a punch 504 extending through the middle area of ​​the spring 503. The top of the punch 504 is movably connected to the bottom of the upper die transition plate 505. The bottom of the upper die transition plate 505 is movably connected to the top of the guide post 502. The bottom of the upper die transition plate 505 is movably connected to the top of the spring 503. The top of the upper die transition plate 505 is movably connected to the upper template 506.

[0028] In this embodiment, as Figure 2 As shown, the lower mold assembly 4 includes a support plate 401, and a lower mold 402 is provided on the top of the support plate 401. A blanking groove 403 is provided in the middle of the lower mold 402, and a lower mold insert 404 is provided in the middle of the upper part of the lower mold 402. A lower mold punch 405 is provided through the lower part of the lower mold insert 404, and the lower mold punch 405 is located above the blanking groove 403. Several stepped pins 406 are installed on one side of the lower mold insert 404, and several guide pin grooves 407 are provided on the top of the lower mold 402. The guide pin grooves 407 are symmetrically distributed about the horizontal center line of the lower mold 402.

[0029] In this embodiment, as Figure 2 and Figure 3 As shown, the lower die 402 and the upper die 501 can fit together, and the outer wall of the guide post 502 is movably sleeved with the inner wall of the guide post groove 407, and the outer wall of the punch 504 is movably sleeved with the inner wall of the lower die punch groove 405.
