This molding method requires a large number of molds to be put into production, which increases the production cost. In addition, it takes a lot of space to store these molds and requires manual management. The last method is to put into production several molds with fixed angles, and then manually correct them after molding to achieve the required angle. Although this method reduces the mold investment, the labor cost also increases, and it also reduces the surface quality of the parts. Utility Model Content
