Description

A bending machine mold

technical field

The utility model relates to a mold, in particular to a bending machine mold.

Background technique

Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. The bending machine is a kind of equipment used for bending sheet materials. The bending principle is to place the workpiece on the plane of the lower die. When the upper die presses the lower die, the workpiece forms a bending angle under the action of the upper and lower dies.

In the mold processing industry, there are often some products that need to achieve front bending and side bending at the same time. For this type of product, the existing mold structure can only realize the front bending or side bending of the product. The traditional method is to design two sets Stamping dies, and then this type of product is divided into two steps for stamping. Therefore, not only the manufacturing cost of the mold is high, but also the process is relatively complicated, and the processing efficiency is extremely low. Due to the need to disassemble the product multiple times and position the product multiple times at the same time, the error increases, which greatly affects the accuracy of the product. It cannot meet the higher and higher requirements of modern industrial production on the production molds of such products.
