Failure and its elimination of injection mold

The structure of the injection mould shape and mold processing quality directly affects the quality of plastic products and production efficiency. Injection mould and plastic products production practice, the most common, some of the most common mould fault and its main reason analysis are as follows.

1. Cooling bad or waterway is leaking. Mold cooling effect directly affect the quality and production efficiency of products, such as poor cooling, products or contraction become warped by uneven surface defects such as deformation. Die global or local overheating on the other hand, make the mold can't normal molding and production, severe cases make the plunger activities such as a thermal card die damage. The cooling system design, processing to the product shape, don't cry because it is complicated or difficult to machining mould structure and eliminate the system, especially in large and medium-sized mold must give full consideration to the cooling problem.

2. Some injection mould for template size restrictions, guide groove length is too small, the slider on the outside of the core-pulling action after the show guide, so that at the beginning of the core-pulling and mode after reset stage are likely to cause the slider tilt, especially in mould clamping, slider reset, make the slider damage, even bending failure. Root experience, slide block core pulling was finished, to stay in the length of the sliding groove should not be less than two-thirds of length guide.
