In addition, the plenum locking assembly 9 may also be disposed at the end of the limiting member 8 or on the back surface of the mold plate 5, and may be moved synchronously with the limiting member 8 or the mold plate 5, which is also considered as an embodiment of the present invention. The pressurizing locking assembly can stretch and retract along the axial direction of the limiting working surface so as to achieve the purpose of clamping the die assembly 4. The pressurization locking assembly can be of a cylinder structure or an oil cylinder structure, and the pressurization locking assembly and the oil cylinder structure are regarded as specific implementation modes of the embodiment.
In this embodiment, the limiting working surface 2 may be formed by a side wall of a positioning plate fixedly connected to the frame 1, or may be formed by a wall surface on the frame 1. Because the frame 1 body has better deformation resistance, the limit working face 2 formed by the wall surface of the frame 1 has better deformation resistance, and the guide rod bridged between the limit working faces 2 is omitted, so that the structure is effectively simplified, the raw material consumption is effectively reduced, and the assembly, processing and transportation costs are reduced.
