1. What are the main points of continuous mold maintenance?

The maintenance of the continuous mold must be done carefully and patiently, step by step, and must not be carried out blindly. Due to the failure of the mold repair, a material belt must be attached to facilitate the inquiry of the problem. Open the mold, check the condition of the mold, check the condition of the mold, identify the cause of the failure, find out the problem, and then clean the mold before removing the mold. When removing the mold, the force should be uniform. For the mold structure of the stripper spring between the fixed plate and the stripper plate and the stripper spring directly on the inner guide bushing, the stripper plate should be removed to ensure that the stripper plate pops out in balance. The inclination of the stripper plate may cause a breakage of the punch in the mold.

(1) Maintenance of convex and concave dies

When disassembling the male and female mold, pay attention to the original condition of the mold, so that it can be easily restored during subsequent mold loading. If padding or displacement is required, the thickness of the gasket must be engraved on the part and a record must be made. Whether the block die is smooth, and whether the gap between the insert and the die is uniform, and the replacement of the die must also be tested to see if the gap between the punch and the punch is uniform. For the shortening of the punch after repairing the punch, a pad is required to reach the required length. Should check the effective length of the punch is sufficient. Replace the broken punch to find out the reason, and at the same time, check whether the corresponding punch has a chipped edge and whether it needs to grind the cutting edge. To assemble the punch, check the punch and the fixed block or fix it. If there is enough clearance between the plates, check if there is any margin for movement if there is a pressure block. The assembly die should be placed horizontally, and then placed with a flat iron block, such as a copper rod, and tapped into place with a copper rod. Tap diagonally and forcefully, and the bottom of the die should be chamfered. After installation, check whether the die surface is flat with the die surface. After the punch die and the core are assembled, make necessary checks against the tape, and check whether the parts are installed incorrectly. Or reversely installed, check whether the die and die block is reversed, whether the blanking hole is blocked, and replace it with a new one. Whether the material needs to be stolen, whether the material needs to be stolen, and whether the mold needs to be locked. Please pay attention to the locking of the screw of the stripper plate. When locking, it should be locked from the inside to the outside with a balanced force. Tighten one screw and then tighten the other screw, so as not to cause the stripper plate to tilt and cause the punch to break or the precision of the mold to decrease.
