How to use and maintain molds to extend the life of hardware molds?

The life of a hardware mold refers to the number of parts that can be formed under the premise of ensuring the quality of the parts. It includes repeated sharpening and replacement of wearing parts, until the main part of the mold is replaced with the total number of qualified parts formed. The correct use, proper maintenance and repair of hardware molds are an important measure to extend the life of the mold. When using hardware molds, pay attention to the following aspects: (1) Ensure that the upper mold is balanced and lifted during assembly and disassembly of the hardware mold to prevent the upper mold from being excessively tilted and causing the guide sleeve to break. (2) When assembling and disassembling the elastic unloading plate, the unloading screws should be tightened or loosened alternately to ensure that the unloading plate is balanced up and down. (3) When disassembling mold parts, pay attention to the original condition and make a mark to facilitate resetting during mold assembly. (4) When replacing the punch, put the punch into the female mold first, and check whether the clearance between them is proper. After the total length of the punch becomes shorter after maintenance, check whether the length is appropriate after adding the backing plate to avoid interference with the unloading plate. (5) After the mold has been disassembled and assembled for many times, the positioning pin hole may become larger due to wear, resulting in uneven blanking clearance, which can be adjusted by shifting. (6) When replacing the spring and rubber, confirm whether the size and compression are appropriate, so as to avoid convex bending and breaking. Factors that should be considered in the maintenance of hardware molds: regular lubrication of the mold guide parts, regular lubrication of the cutting edge and stretching die, timely cleaning of waste materials, keeping the mold clean, and regular inspection of the spring, rubber and guide parts of the mold for damage or failure. Replace if necessary. Dongguan Hardware Co., Ltd. has been dedicated to precision metal stamping molds, precision metal stamping, and precision mold processing for 15 years.
