Description

A jacking mechanism for a stamping die

technical field

The invention relates to the technical field of molds, in particular to a material ejecting mechanism of a stamping mold.

Background technique

Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing. It is called cold stamping die (commonly known as cold stamping die). Stamping is installed at room temperature The mold on the press presses the material to cause separation or plastic deformation to obtain a press processing method for the required parts. The materials for manufacturing stamping molds include steel, hard alloy, steel-bonded hard alloy, and zinc-based Alloys, low melting point alloys, aluminum bronze, polymer materials, etc., after the stamping is completed, the workpiece is taken out by using the ejector mechanism.

After searching, the Chinese patent discloses a metal stamping die jacking mechanism (authorized announcement number CN206763790U). This patented technology can select different jacking methods according to the ground contact force between the workpiece and the lower die seat, which greatly improves the stamping process. The ejection efficiency of the mold improves the extraction efficiency of the workpiece and saves the workload of the ejection after the stamping process, but it is not convenient to buffer the strength of the workpiece during the initial pressing process, making the stability of the workpiece when it is pressed and pushed out. Poor, and the ejector mechanism itself does not have the function of dust removal, and it is not convenient to dissipate heat from the bottom of the workpiece. At the same time, it is cumbersome to operate. Therefore, we propose a ejector mechanism for stamping dies.
