Injection mold failure how to solve, mold factory eliminate small trick 123
injection mold failure,need to solve in time to ensure production efficiency and product quality. The mold factory provided a few tips for troubleshooting, these include damage of guide post, difficulty of gate stripping, deviation of movable and fixed mould, bending of movable mould plate, ejector rod problem, bad cooling, insufficient length of guide groove and failure of fixed distance tensioning mechanism. The solution of these problems is very important for the normal operation of the die.
1, the guide post in the mold guide role is crucial, the damage guide post will lead to the injection of a huge lateral offset force, affect the normal operation of the mold. In order to solve this problem, it is necessary to pay attention to the uniformity of the wall thickness and the symmetry of the side of the plastic part.
2, the difficulty of gate stripping will lead to product damage and affect production efficiency. Attention should be paid to the finish of the tapered gate and the choice of materials to ensure smooth gate out.
3, the migration of moving and fixing die is a common problem in large-scale dies, which needs to be solved by adding a high-strength locating key on the parting surface of dies. In addition, the choice and quality of moving templates are also critical.
4, the ejector rod bending, fracture or leakage problems need to pay attention to the ejector rod and hole clearance to ensure the normal operation of the ejector rod. The design of cooling system and cooling effect have direct influence on product quality and production efficiency, which need special attention.
5, the insufficient length of guide slot and the failure of the fixed-distance tensioning mechanism are also common problems, which need to pay attention to the position of the slider in the core-pulling action and the synchronization of the mechanism.
In general, injection mold failure, we need to take appropriate measures according to the specific situation to ensure the normal operation of the mold and production efficiency. The trouble shooting tips provided by the mold factory have played an important guiding role in solving these common problems.
