Maintenance precautions for metal stamping convex and concave molds. Many people know that in the production of metal stamping molds, it is necessary to maintain the machine and carefully inspect it in order to improve the mold life and production efficiency.
1. When disassembling convex and concave molds, attention should be paid to the original condition of the mold for easy restoration during subsequent mold installation; If there is padding or displacement, the thickness of the gasket should be engraved on the part and recorded.
2. When replacing the convex mold, it is necessary to test whether the insertion and removal block of the concave mold are smooth, and whether the gap between the insertion and the concave mold is uniform; When replacing the concave mold, it is also necessary to test whether the gap between the insertion and the punch is uniform.

3. Regarding the need to add shims to achieve the required length for the shortened convex mold after grinding, it is necessary to check whether the effective length of the convex mold is sufficient. To replace a broken convex mold, the cause should be identified, and the corresponding concave mold should be checked for any broken edges and whether grinding of the edges is necessary.

4. When assembling the convex mold, it is necessary to check whether the gap between the convex mold and the fixed block or plate is sufficient, and if there is a pressure block, it is necessary to check whether there is enough clearance left. The assembled concave mold should be placed horizontally, and then a flat iron block should be placed on the surface of the concave mold. Dongguan metal products should be lightly tapped into place with a copper rod, and cannot be forcefully tapped in diagonally. The bottom of the concave mold should be chamfered. After installation, check whether the concave mold surface is flat with the mold surface.
5. After the assembly of the convex mold, concave mold, and mold core, necessary inspections should be carried out on the care belt to ensure that all parts are installed correctly or in reverse. Check whether the concave mold and concave mold cushion block are installed in reverse, whether the feeding hole is blocked, whether new parts need to be stolen, whether there is enough need for stealing, and whether the parts of the mold that need to be locked are locked.
6. Dongguan metal product hardware stamping parts manufacturers should pay attention to the confirmation of the locking of the stripping plate screws. When locking, it should be done from the inside out, with balanced force and cross locking. It is not allowed to lock one screw first and then lock another screw to avoid tilting the stripping plate, causing the convex mold to break or the mold accuracy to decrease.
