Description

Trimming and punching composite die Technical Field The application relates to the technical field of composite dies, in particular to a trimming and punching composite die. Background The mould is a tool for forming articles in industrial production, and can be divided into a metal forming mould and a nonmetal forming mould according to forming materials, single-procedure, compound, progressive and other moulds according to technological functions and structures, and can be divided into moulds for automobiles, electronics and the like according to application fields, and can be divided into precise moulds, large moulds and the like according to precision and technical difficulty by applying pressure, heat and the like to raw materials to enable the raw materials to be subjected to physical or chemical change according to specific shapes and sizes so as to manufacture parts or products with preset shapes and functions. The publication number CN222643001U discloses a side cut compound die that punches a hole, and under this patent through the interact of structures such as reference column, first spring, punching press layer, side cut layer, progressive column and second spring, accessible top layer mould and middle level mould's progressive decline effect, accomplish punching press and side cut operation respectively, the post that punches a hole in the subassembly that punches a hole again, can once only accomplish the processing, save processing procedure reduce cost, have fine shaping effect and practicality. Although the stamping and trimming operation can be completed in the patent, after the stamping of the product is completed, the stamped product can be left in the lower die seat, and the product of the lower die needs to be manually taken out, so that safety accidents such as hair damage, bruise and the like are easily caused. Disclosure of utility model In order to solve the problems, the application provides a trimming and punching composite die. The application provides a trimming and punching composite die which adopts the following technical scheme: The trimming and punching composite die comprises a base, wherein a footstock is arranged at the top of the base, a lower die is arranged at the top of the base, and an ejection assembly is arranged below the lower die; The ejecting subassembly includes the roof, and the quantity of roof sets up to two, and the cavity has been seted up to the inside of base, and the inside sliding connection of cavity has the connecting rod, and the equal fixed connection in both ends of two roof and connecting rod, the inside threaded connection of connecting rod have two screw thread sections, and the equal fixedly connected with movable rod in bottom of two screw thread sections, two dismantlement cavities have been seted up to the inside of base.
