Internal pressure side push forming mechanism

Abstract

This utility model relates to the field of mold technology, specifically an internal pressure side-push forming mechanism. The internal pressure side-push forming mechanism is characterized by: a lower pad plate connected to the bottom of the lower mold base, a lower clamping plate connected to the top of the lower mold base, a lower ejector plate above the lower clamping plate, lower mold bending blocks on the left and right sides of the lower ejector plate, and pull-back blocks on the outer sides of the lower mold bending blocks on both sides, respectively connected to the lower mold bending blocks via pull-back screws and springs; a lower mold driving block is located between the lower mold bending blocks and the pull-back blocks, with the other end of the lower mold driving block passing through the lower ejector plate and the lower clamping plate and connecting to the lower mold base; the bottom of the lower ejector plate abuts against one end of a tension / compression spring, and the other end of the tension / compression spring passes through the lower clamping plate and is located inside the lower mold base. Compared with the prior art, by cooperating with the upper mold bending block, the internal pressure side-push forming lower mold bending block achieves the effect of bending on both sides, reducing rework issues.
