How to maintain the continuous mold convex and concave mold

Netizens ask: How should the continuous mold male and female molds be maintained? 　　 Expert reply: When disassembling the male and female molds, pay attention to the original condition of the mold, so that it can be easily restored during subsequent mold assembly. If there is a pad or shift, a gasket should be engraved on the part. Thickness and make a record. To replace the punch, try to insert the stripping block and the die to see if it is smooth, and whether the gap between the insert and the die is uniform, and whether the gap between the die and the punch is even when changing the die. In view of the shortening of the punch after grinding the punch, it is necessary to add gaskets to reach the required length, and check whether the effective length of the punch is sufficient. To replace the broken punch, it is necessary to find out the reason, and check whether the corresponding concave mold has chipping and whether it is necessary to grind the cutting edge. When assembling the punch, check whether the gap between the punch and the fixed block or the fixed plate is sufficient. If there is a press block, check whether there is room for movement. The assembling die should be placed horizontally, and then set it with a flat iron block such as a copper rod on the die surface to tap it in place. Do not place it diagonally and force it in. The bottom of the die should be chamfered. After installation, check whether the surface of the concave die is even with the surface of the die. After the punch and die cores are assembled, the necessary inspections should be made against the material belt, whether the parts are installed incorrectly or reversely, check whether the concave mold and the concave mold pad are installed reversely, whether the blanking hole is blocked, and whether the new parts need to be replaced. Stealing material, whether the material needs to be stolen is enough, and whether the mold needs to be locked tightly. Pay attention to the confirmation of the locking of the stripper plate screws. When locking, it should be cross-locked from the inside to the outside with a balanced force. Do not lock one screw first and then lock the other screw, so as to avoid the stripper plate tilting and causing the punch to break or The accuracy of the mold is reduced.
