An up piston cylinder, a down piston cylinder, an up bed piece (11), a down bed piece (31), an up concave mould seat (15), a down concave mould seat, an up concave mould (16), and a down concave mould (33) are fixed at the up bottom plate and the down bottom plate. An up pin-lift (3), a down pin-lift (24), an up punch pin seat (4), a down punch pin seat (22), an up punch pin (38), and a down punch pin (36) form an up piston and a down piston respectively. The up piston cylinder and the down piston cylinder have a split combined structure, which is convenient for manufacturing, installation, and maintenance.
