In the initial design of the mold, only considering the characteristics of the binder, ignoring the pressing core forming guide slide stroke.

2. there is an error in the design of the mould processing parts and drawings

This part is marked in the drawing area which needs to be processed. But because of the complex core surface, the die is machined after the forming of the casting, and then the gap between the working surface and the concave die guide surface is formed. The left and right swing of the press core is found during the normal operation of the die.
