Description

A mold punching device

technical field

The utility model relates to the technical field of molds, in particular to a mold beating device.

Background technique

In the current industrial production, the mold is one of the important process equipment, which is widely used in various production industries such as casting, forging, stamping, plastics, powder metallurgy, and ceramic products. Usually the mold is composed of an upper mold and a lower mold. The upper mold is fixed on the press table or backing plate. When working, the blank is positioned on the surface of the lower mold by positioning parts, and the press slider drives the upper mold to press down. Under the action of the working parts of the mold (ie, punch and die), the blank will be separated or plastically deformed, so as to obtain the desired shape and size of the product. When the upper mold rises, the unloading and ejecting device of the mold unloads or pushes or ejects the stamping or sheet from the convex and concave molds for the next working cycle. The feeding mechanism is a mechanism that pushes out the workpiece or sheet from the mold. In some cases, the existing feeding device has difficulty in removing the material, and cannot quickly push the product out of the mold, which affects product quality and work efficiency. .
