step two, a step two is carried out; when the workpiece is subjected to die casting forming, the trapezoid clamping plate (31) and the movable template (35) can be driven to slowly rise through the structural cooperation of the local pressing mechanism (3), and the thin-wall part with the interlayer on the vertical surfaces of the thin-wall template (42) and the movable template (35) can be subjected to secondary extrusion, so that the local die casting effect of the thin-wall part is achieved;
step three, a step of performing; after the thin-wall part is die-cast, the upper die holder (1) and the lower die holder (2) can be separated, and the structure of the local jacking mechanism (3) is continuously started to drive the trapezoid clamping plate (31) and the movable die plate (35) to drive the die-cast thin-wall part to lift, so that the lifted thin-wall part is taken out.
