In this patent, the mold is fixed by lifting and lowering the pressure plate and the movable push block;

[0005] However, in this patent, there is only one movable push block for fixing the mold circumferentially, so only one side of the mold can be limited and fixed, and the other sides of the mold cannot be fixed. This may cause the mold to move during use, and the lifting and pressing plate only has the function of pressing the mold, and cannot limit the upper part of the mold. This may cause the mold to move during use, which will affect the quality of the manufactured products to a certain extent.

[0006] Therefore, it is necessary to design a fixing device with a more stable mold fixing effect. Utility Model Content
