AI Technical Summary

Technical Problem

In the prior art, the deep cavity structure of the stepped part hinders the effective penetration of lubricant, resulting in increased friction between the material and the mold surface, causing scratches and difficulty in demolding, and also causing deformation of the parts.

Method used

The stepped automotive body curved surface stamping die is adopted. Through the design of the ejection mechanism and clamping mechanism, and the use of motor-driven gear transmission and electric push rod transmission, the die can be stably ejected and accurately positioned, reducing friction and deformation.

Benefits of technology

It effectively reduces uneven resistance during mold release, prevents deformation and cracking, improves the accuracy and reliability of the processing, and ensures the stability of the mold and the quality of the processing.

Abstract

The utility model relates to the technical field of automobile shell processing, especially step -type automobile shell curved surface punch -press mould, including the processing platform, the top fixedly connected with the push piece ware of processing platform, the bottom of push piece ware installs the upper die, the top wall rear side equidistance fixedly connected with a plurality of fixed plates of processing platform, the inner wall of processing platform is installed and ejects mechanism, and the ejecting mechanism is used to eject the mould. In the utility model, the fixed block is used to lift the mounting plate to move upward, the telescopic rod is first lifted the mould, when the bidirectional pulley slides to the upper limit of the sliding groove, one side of the bidirectional pulley will be downward, and the bidirectional pulley rotates on the clamping block to make the other side lift the mounting plate again, the mounting plate compresses the spring and makes the telescopic rod eject the mould, the spring can also reduce the vibration in the ejecting process, prevent damaging the mould, realize the process that the mould is separated from the lower die, and the uneven stress of different parts resistance is reduced, and the deformation and cracking defects of uneven stress are caused.
