Abstract

The invention relates to the field of stamping dies, and aims to provide a die ejector pin structure and an ejector pin installation method. A mold ejector structure, comprising: a workbench, a supporting plate located at the lower side of the workbench, a ejector group consisting of a plurality of ejector pins, a lifting device for the supporting plate, and a lower die; the upper end of the workbench is provided with: Several rows of guide holes that penetrate the lower end of the worktable and match the diameter of the mandrel; the lower mold includes: a lower mold base with sliding holes passing through the upper and lower ends; The mold core; the lower mold base is detachably connected to the upper end of the worktable; the supporting plate supports the lower end of the ejector rod; the upper end of each ejector rod passes through a guide hole and extends into the sliding hole. The ejector pin structure of the mold can be adjusted according to the needs of processing workpieces, and the ejector pins can be used in common for different large stamping dies.

Description

Technical field [0001] The invention relates to the field of stamping molds, in particular to a mold ejector rod structure and an ejector rod installation method. Background technique [0002] The stamping die has an ejector rod for ejecting the workpiece; the utility model of Chinese Patent Application No. CN201220346913.5 discloses a new type of steel plate die ejector rod structure, including a lower template, which is provided with a guide hole, and the mold ejector rod penetrates Through the guide hole, the end of the mold ejector rod is fixedly connected to the ejector rod support plate. When working, the press ejector rod of the press can be completed by acting on the ejector rod support plate. There is no need to pay attention to the position of the press ejector rod, which can reduce the pressure. The time for placing and centering the ejector rod of the machine is easy to operate, has the advantages of simple manufacturing process and good balance of the ejector rod of ...
