An undercut forming punching mechanism arranged in a mold

Abstract

The invention relates to the technical field of punching, and specifically discloses an undercut forming punching mechanism arranged in a mold, which is arranged in an upper mold of a forming mold frame, and includes a slider forming mechanism and a punching mechanism. The slider forming mechanism includes The slider pushes the cylinder and the forming slider, the slider pushes the cylinder and is fixed on the upper die, and the output end of the slider pushes the cylinder to connect with the forming slider; the punching mechanism includes the punch pushing the cylinder, the punch and the fixed insert, and the fixed insert The block is fixed on the upper die, the punch pushing cylinder is fixed on the fixed insert, and the punch is fixed at the output end of the punch pushing cylinder. The undercut forming and punching mechanism of the present invention is mainly used for forming and punching the carpet with inwardly concave holes in the interior parts of the automobile. The concave hole is punched, so that forming and punching can be completed at one time, which improves work efficiency, reduces process turnover, and ensures product quality.

Description

technical field [0001] The invention relates to the technical field of punching, in particular to an undercut forming punching mechanism arranged in an automobile carpet forming mold. Background technique [0002] Car carpet is a kind of interior decoration that covers the interior body floor of the car. It is a kind of carpet specially produced according to the shape of the car interior. There is an existing automobile front compartment carpet whose tail has a larger profile concave part, and the other end head opposite to the tail is smaller than the concave area of ​​the tail. After the surface blanket is heated and baked, the softened surface blanket is put into a single-molding mold for pressing and forming. After cooling and shaping, the boundary and hole positions are punched out to obtain a car carpet. This needs to be completed through multiple steps, and the production efficiency is low. So we need to design a mechanism for undercut forming and punching holes on t...

AI Technical Summary

Problems solved by technology

There is an existing automobile front compartment carpet whose rear part has a larger contour concave part, and the head of the other end opposite to the rear part is smaller than the concave region of the rear part. After the surface blanket is heated and baked, the softened surface blanket is put into a single-molding mold for pressing and forming. After cooling and shaping, the boundary and hole positions are punched out to obtain a car carpet. This needs to be completed through multiple steps, and the production efficiency is low. Therefore, we need to design a mechanism for undercut forming and punching holes on the concave part of the car carpet, so as to improve production efficiency
