[0031] Meanwhile, when the lower sliders 10 move towards the driving mechanism, the lower sliders 10 or the second locking block 8 may be lowered, which needs to be reset after the mold is pulled out. Since the lower sliders 10 are arranged inside the lower mold plate 4, the buffer cavity is arranged on the lower mold base 3, so the guide column 12 can be arranged between the lower mold plate 4 and the bottom wall of the buffer cavity, the buffer spring is arranged on the guide column 12, and the upper end surface of the buffer spring abuts against the lower surface of the lower mold plate 4, so that the reset of the lower sliders 10 or the second locking block 8 can be ensured.
