When disassembling precision metal stamping molds, there are many details that need to be paid attention to. If you are not careful, you may damage the accessories, such as the pin hole, which is particularly easy to be damaged during mold disassembly. Do you know why?

The reasons and solutions for compensating trade damage to the pin holes during the disassembly and assembly of precision hardware stamping molds are as follows:

1、 Pin holes are easily damaged if not wiped clean

We can clean the pin holes and pins. When disassembling the mold, the positioning pin should be removed first. When installing the mold, the screw should be used to guide it, and then the positioning pin hole should be drilled.

2、 Incorrect mold assembly and disassembly program

The solution is to avoid damaging the pin hole when knocking down the pin

3、 When the wall of the pin hole is roughened or scratched, resulting in too tight assembly of the mold, carefully check whether the pin hole is roughened. Otherwise, the pin hole should not be drilled out. If the pin hole is misaligned or there is no escape hole below, add a positioning pin escape hole.

Pins are essential components in the process of disassembling and assembling stamping molds. Therefore, when installing or repairing precision hardware stamping molds, we must pay attention to the pin holes and not damage them.
