[0012] Preferably, the wedge module further comprises a pad block which is sleeved on the first wedge and abuts against the bottom of the auxiliary module and the convex block synchronously, and when the mold is opened, the pad block drives the auxiliary module and the convex block to move upward synchronously. In this way, the synchronous upward and downward movement of the auxiliary module and the convex block is ensured, and the synchronism of the movement of the workpiece and the convex block is achieved.
[0013] Preferably, a guide groove which extends upward and downward is formed on the second wedge, wherein the inner wall of the guide groove forms the second inclined surface, and the concave block is inserted into the guide groove, and when the mold is closed, the upper die presses downward to the concave block.
[0014] Preferably, the included angle between the first inclined surface and the horizontal plane is equal to the included angle between the second inclined surface and the horizontal plane.
