[0010] As an improvement, the first cam and the second cam are sleeved on a vertically arranged rotating shaft, and the motor drives the rotating shaft through a belt.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The first cam drives the stamping assembly to move, and the second cam drives the stamping assembly to act. The first cam and the second cam work in coordination. When the first cam drives the stamping assembly to move to a predetermined position, the second cam drives the two stamping assemblies to form a mold closing state. The action continuity is good and the production efficiency is high. The stamping station is separated from the equipment, which helps to realize automatic loading. BRIEF DESCRIPTION OF THE DRAWINGS
