AI Technical Summary

Technical Problem

Existing molds are prone to slippage when adjusting the position of the punching structure, resulting in changes in the punching position. Furthermore, it is not convenient to increase or decrease the number of punching structures according to requirements, making them impractical.

Method used

A mold workpiece comprising an upper mold and a lower mold is designed, employing a combination structure of a horizontal plate and a mounting plate. The punching head is flexibly adjusted via a fixing bolt connection, and slots are provided in the lower mold to facilitate waste material discharge. The upper mold is stabilized and precise by combining a hydraulic cylinder and a guide rod.

Benefits of technology

It improves the adaptability and practicality of the mold, ensures the accuracy and stability of the punching head position, and enhances the punching precision and efficiency of the adhesive-coated copper foil.

Abstract

The utility model discloses a die workpiece suitable for punching a glue-containing copper foil, which comprises an upper die, a lower die arranged below the upper die, an upper die cavity arranged inside the upper die, a transverse plate fixedly mounted inside the upper die cavity of the upper die, a mounting plate arranged below the transverse plate, a punching head fixedly mounted below the mounting plate, and a lower die arranged below the punching head. The mounting plate is a U-shaped plate, a fixing bolt is arranged in the mounting plate, a long-strip-shaped hole is formed in the transverse plate, and the transverse plate is fixedly connected with the mounting plate through the fixing bolt. According to the die, the capability that the position of a punching structure is stable after adjustment is achieved, practicability is improved, and therefore the problems that an existing die is prone to sliding after the position of the punching structure is adjusted, the punching position is changed, and the number of punching structures is not convenient to increase or decrease according to needs are solved.
