AI Technical Summary
Technical Problem
Traditional demolding mechanisms can easily cause workpiece deformation, surface scratches, and mold jamming when removing the tight adhesion between the automotive pillar interior panel and the mold, affecting production efficiency and product qualification rate.
Method used
The ejection mechanism combines a striking rod and a vibration mechanism, and uses an electric push rod to drive mechanical structures such as a ball screw, wave ring, and triangular block to achieve synchronous coordination of ejection and vibration actions, thereby breaking up adhesion.
Benefits of technology
It effectively avoids workpiece deformation and surface scratches, improves product qualification rate, reduces labor intensity of manual separation, and improves demolding efficiency.

Abstract
The utility model relates to die stripping technical field, and disclose a kind of stripping mechanism of automobile stand column interior trim panel injection mold, including frame, the inner wall of frame is fixedly connected with die by support rod, the inside of frame is provided with ejection mechanism, the ejection mechanism includes knock-out assembly and knocking rod, knock-out assembly is set in the inside of frame, and the knocking rod is set on knock-out assembly. The utility model is reciprocating knock to knock-out plate bottom by knocking rod in ejection mechanism, cooperate and vibrate mechanism in vibration knock of knock block to the vibration knock of die side, double effect can effectively break the close adhesion of automobile stand column interior trim panel and die cavity, avoid the workpiece deformation, surface scratch or jam phenomenon caused by traditional single knock, significantly improve product pass rate.
