Special-shaped spring manufacturers are due to the small process content, small curved cheek, particularly complex workpiece, but also need shape forming. Therefore, it is necessary to form the molded core and forming surface, and the forming conditions of the mold structure are very large. The pressing area is small.
Designers will consider the characteristics of the special spring, but ignore the core of the irregular sliding stroke, but this is often flawed:
At the beginning, because the pressure core is a complex type, the casting is used to process the guide surface after the casting molding, resulting in clearance error after the machining surface and the concave guide surface slip. In the normal operation of the mold, the left and right swing of the pressure core occurs.
