8 Tips to troubleshoot injection mold failures

The most common problems with this mechanism are inadequate processing and the use of small materials. There are two main problems:

The angle of inclination pin A is large;

The advantage is that a large core-pulling distance can be produced in a short mold opening stroke.

However, if the inclination angle A is too large, when the pulling force F is a certain value, the bending force P = F / COSA that the oblique pin receives during the core drawing process is larger, and the oblique pin deformation and oblique hole wear are likely to occur.

At the same time, the oblique pin produces an upward thrust N = FTGA on the slider, which increases the positive pressure of the slider on the guide surface in the guide groove, thereby increasing the frictional resistance when the slider slides. Easy to cause sliding irregularities, guide groove wear. According to experience, the inclination angle A should not be greater than 25 °.
