Mold processing refers to the molding and blanking tools, in addition to shear molds and die-cutting molds. Typically, the mold has two parts, upper and lower molds.
Below small editor to say a few tips for mold processing.
Choice of mold clearance: The gap of the mold is related to the type and thickness of the stamped material. Unreasonable clearance can cause the following problems, such as the gap is too large, the stamping work piece of the burr is relatively large, the quality of stamping is poor. If the gap is small, although the quality of the punch is better, but the mold wear is more serious, greatly reducing the life of the mold, and easy to cause the break of the punch.

Gaps are too large or too small to produce adhesion on the punch material, resulting in stamping. Too small gap is easy to form a vacuum between the bottom surface of the punch and the plate and waste rebound, reasonable clearance can extend the life of the mold, discharge effect is good, reduce burrs and flipping edges, plate to maintain clean, the aperture consistent will not scrape the plate, reduce the number of blade grinding, keep the plate straight, punch positioning accurate.
The importance of mold edge grinding: regular edge grinding mold is the guarantee of consistency of punch quality. Regular edge grinding mold can not only improve the life of the mold but also improve the service life of the machine, to master the correct timing of cutting. So what are the ways to grind the edges? Mold edge grinding has a variety of methods, can be used with a special edge grinder can also be achieved on the flat grinder. The frequency of punch and die edge grinding is generally 4:1, please adjust the mold height after the edge grinding.
