Through the provided telescopic spring, the template can be moved up and down through its own telescopic cooperation.

Preferably, the bottom end of the telescopic spring is fixed to the top of the mounting plate, and the top end of the telescopic spring is fixed to the bottom of the template.

Through the provided telescopic spring, the template can be moved up and down through its own telescopic cooperation.

Preferably, the bottom of the formwork is an open structure, and the specifications of the formwork match those inside the formwork, and a buffer pad is fixed on the top of the formwork.

Through the provided buffer pad, when the movable plate moves down, the impact force between the movable plate and the top of the formwork can be buffered.

Preferably, both ends of the outer walls on both sides of the movable plate are fixed with sliding sleeves, and the sliding sleeves are sleeved and slide on the outer walls of the guide rods.

By sliding the sliding sleeve on the guide rod, the movable plate can be guided up and down, so that the stamping head is more stable during stamping.

The beneficial effects of the utility model are:

When the material is pressed into the mold shell by the punching head, the material contacts the formwork, and the formwork is pressed downwards, so that the two telescopic springs shrink into the through holes of the shock-absorbing pad, and the bottom of the formwork contacts the shock-absorbing pad. The shock-absorbing pad relieves the impact force on the formwork, which can effectively reduce the impact force on the formwork and effectively improve the service life of the mold.
