The movement of plate 3 provides a guiding effect, and the pressing plate 3 moves downward to punch the upper mold 51 at the bottom of the top plate 5. During the punching process, the top plate 5 moves downward, and the spring 43 contracts synchronously. The slide bar 42 synchronously provides a guiding effect for the movement of the top plate 5. At this time, the reinforcing rod 62 is subjected to force to adjust the angle, driving the connecting seat 63 to slide on the first slide bar 64. At this time, the first spring 65 is compressed or stretched, and the elastic action of the first spring 65 alleviates the impact of the hydraulic cylinder 71 and the upper mold 51 on the lower mold 41, thereby protecting the molds from being damaged by severe impact.
