Internal pressing and lateral pushing forming mechanism

By cooperating with the upper die bending block of the internal pressure side-push forming mechanism, a secondary bending effect that cannot be achieved by traditional pressing dies is realized, solving the problems of inaccurate product positioning and high scrap rate, and improving production efficiency and product quality.

AI Technical Summary

Technical Problem

Traditional compression molding can only achieve one-time bending and forming, which cannot meet the needs of diversified products. This leads to increased costs for additional mold procurement, inaccurate product positioning, and higher scrap rates.

Method used

Design an internal pressure side-push forming mechanism, which achieves the bending effect on both sides by cooperating with the lower die bending block that can be internally pressured and pushed, and realizes secondary bending by utilizing the cooperation structure and driving mechanism of the upper and lower die bending blocks.

Benefits of technology

It enables precise control of product bending angle, reduces product defect rate and rework, improves production efficiency and product quality, and reduces mold procurement costs.

Abstract

The utility model relates to the technical field of dies, in particular to an internal pressing and lateral pushing forming mechanism. An internal pressing and lateral pushing forming mechanism is characterized in that the bottom of a lower die base is connected with a lower base plate, the top of the lower die base is connected with a lower clamping plate, a lower stripping plate is arranged above the lower clamping plate, lower die bending blocks are arranged on the left side and the right side of the lower stripping plate respectively, and pull-back blocks are arranged on the outer sides of the lower die bending blocks on the left side and the right side respectively. The pull-back blocks on the left side and the right side are connected with the lower die bending block through pull-back screws and springs correspondingly. One end of a lower die driving block is arranged between the lower die bending block and the pull-back block, and the other end of the lower die driving block penetrates through the lower stripping plate and the lower clamping plate to be connected with the lower die base. The bottom of the lower stripping plate abuts against one end of a tension-compression spring, and the other end of the tension-compression spring penetrates through the lower clamping plate and is located in the lower die base. Compared with the prior art, through cooperation of the lower die bending block and the upper die bending block which can be formed through internal pressing and lateral pushing, the effect of two-side bending is achieved, and the problem of reworking is reduced.
