Once the synchronization is lost, it will inevitably cause the pull die to tilt. Deformation. The parts of these mold mechanism should have high hardness and wear resistance. Due to its difficulty in adjustment and short service life, it should be avoided as far as possible.

It would be preferable to replace them with other mechanisms.

If the suction of the die hole is small, the fixed die can be rolled out with a spring, and when the core pumping force is large, the core sliding should be used when the dynamic die is inverted, and the core pumping action can be completed before the fractal structure. In large molds, hydraulic cylinders may be used to draw cores.

The Tilt pin slider pulls the core mold mechanism to damage. Most of the faults in this institution are inadequate processing and too small materials. There are two problems: large bevel A, which has the advantages of short excavation stroke and large distance of core. However, when the drawing force F is a certain value, the bending force on the oblique pin p=f/cosa in the process of core pumping, and the oblique pin is prone to deformation and hole wear. At the same time, the upward thrust n=ftga of the oblique pin on the slider increases, which will increase the positive pressure of the slider on the surface of the guide rail in the rail groove. When sliding, the friction resistance of the slider increases, which is easy to cause the sliding uneven shunhe guide rail groove wear. According to experience, inclination a should not be greater than 25 degrees.
