Description

Punching and pressing die

Technical Field

The utility model relates to a die, in particular to a punching and pressing die.

Background

In the prior art, aluminum alloy die castings fed from the side of an aluminum die casting product are formed to leave a feed handle connected to the edge of the product, and are usually removed by hand knockout and trimmed with a tool such as a grinder to conform to the surface energy of the product.

In the product cutting method of vertical pouring gate casting of aluminum die castings, a band saw cut or a saw blade cut is generally adopted to separate a pouring gate from a part. However, since the die casting is often a gate having a complicated shape and gates are present in multiple directions, the cutting must be performed in multiple times. In the process, the method is a repeated, time-consuming and labor-consuming operation.
