Description

Die-cut mould of easy ejection of compact

Technical Field

The utility model relates to a die-cut mould field, in particular to die-cut mould of easy ejection of compact.

Background

The stamping die is a special process equipment for processing metal or nonmetal materials into parts or semi-finished products in the stamping process, and is called as the stamping die. Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part. In the existing metal plate processing, the die can be divided into various dies such as punching, riveting, bending and the like according to process properties, wherein a punching die is one of the dies commonly used in the metal plate processing and can be divided into a single-pass die and a continuous die, and the continuous punching die can continuously punch a plurality of products on a plate which moves axially; the one-way punching die is a die which only completes one punching process in one stroke of a press machine; the existing punching die is often provided with a groove matched with a product, and the product cut after the punching process is finished is positioned in the groove, so that the product and waste materials need to be taken out of the die.

The existing punching die usually adopts an ejector pin or other modes to take out a product from the die, but when the product is tightly clamped in the die, the ejector pin ejects the product or other modes to easily eject the plate, so that operators are injured; meanwhile, the punched waste materials need to be manually taken out, and safety accidents are easy to happen. Therefore, there is a need for a single-pass die cutting tool that can safely remove the product and scrap from the tool.
