What problems should be paid attention to when disassembling continuous molds

Pay attention to the original condition of the mold when disassembling the continuous mold, so that it can be easily restored during subsequent mold assembly. If there is a pad or shift, the thickness of the gasket should be engraved on the part and recorded. To replace the punch, try to insert the stripping block and the concave mold to see if it is smooth, and whether the gap between the insert and the die is uniform, and whether the gap between the plug and the punch is even when replacing the concave mold. 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, find out the reason, and check whether the corresponding die has chipped edges and whether it needs to grind the 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 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 into it. The bottom of the die should be chamfered. After installation, check whether the concave die surface is even with the die surface. After the punch and die cores are assembled, the necessary inspections should be done 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 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.
