The second piston 16 allows gas to enter between the first piston 15 and the second piston 16 through the vent pipe 17, and allows gas to enter the inside of the connecting cover 2 through the vent pipe 17, and the one-way valve controls the gas flow direction of the two vent pipes 17.

[0024] The first piston 15 and the second piston 16 are both in contact with the inner wall of the connecting cover 2, and the outer wall of the lower end of the first piston 15 is designed in an inclined shape. The first piston 15 and the second piston 16 are both relatively sealed with the connecting cover 2, and the power structure 12 drives the upper mold 11 to move vertically, thereby controlling the opening and closing of the lower mold 1 and the upper mold 11, and extruding the workpiece. When the lower mold 1 is closed, the connecting rod 14 drives the first piston 15 and the second piston 16 to enter the inside of the connecting cover 2, and the gas inside the connecting cover 2 is compressed and enters between the first piston 15 and the second piston 16 through the vent pipe 17.
