[0033] Working principle: Under the action of the hydraulic rod 201, stamping is achieved between the upper mold 103 and the lower mold 104. The setting of the guide rod 202 ensures that the upper mounting plate 105 and the upper mold 103 will not deviate when moving downward, and the stamping is more accurate. At the same time, the upper mounting plate 105 drives the connecting rod 203, the spring 204 and the damping rod 205 to move downward together. When the disc at the bottom of the damping rod 205 conflicts with the top surface of the adjusting screw 207, the stamping force between the upper mold 103 and the lower mold 104 is buffered to avoid the upper mold 103 and the lower mold 1 04 is damaged, which is more practical. At the same time, under the setting of the installation mechanism 300, the mold can be replaced, and the application range is wider. By turning the knob 307, the two-way screw rod 301 is driven to rotate with the cooperation of the driven wheel 305 and the driving wheel 306, and then the plug rod 302 threadedly connected thereon is driven to move. The plug rod 302 is connected to the slot 304 on the connecting block 303 to realize the installation of the upper mold 103 and the lower mold 104. When the plug rod 302 is disengaged from the slot 304 on the connecting block 303, the upper mold 103 and the lower mold 104 are disassembled.
