[0002] Currently in injection molding, the molding mold is a tool used to mold objects. This tool is composed of various parts. It mainly realizes the processing of the object's shape by changing the physical state of the molded material. However, in the process of using the molding mold, the two steps of demolding and core pulling often need to be carried out step by step. Traditional molds often pull the core first and then eject it, which will result in a large space required for the slider, a large processing volume, high cost, and an increase in the product molding cycle. Utility Model Content
