A limiting groove is provided on the front side of the upper die 4 and the lower die 5, and a material receiving shell 10 is inserted on the back side of the groove. Rubber pads are provided on the side close to the mounting plates 3 on both sides to improve the stability between the upper die 4 and the lower die 5 and the mounting plate 3.

[0034] Example 2

[0035] Reference Figure 1-6A first limiting mechanism that limits the forward and backward movement of the wedge block 9 is provided inside the limiting groove. The first limiting mechanism includes an internal threaded tube 14 and a threaded rod 13. The internal threaded tube 14 is rotatably provided inside the limiting groove, and the threaded rod 13 is threadedly sleeved inside the internal threaded tube 14.

[0036] Example 3

[0037] Reference Figure 1-6 A transmission mechanism is provided on the front side of the upper mold 4 and the lower mold 5 to simultaneously drive the two internal threaded tubes 14 to rotate.
