AI Technical Summary

Technical Problem

During long-term production, due to factors such as ejector pin wear and mold temperature, the die-cast product may be ejected from the mold cavity, but the stub may stick to the mold ejector pin. This causes misalignment in subsequent processes on the automated production line, making normal production impossible.

Method used

A device for preventing material stalk from sticking to the mold was designed. It uses an inclined power cylinder and a conical separation head. The separation head extends into the bottom of the material stalk to separate the material stalk from the mold ejector pin. The movement of the mold ejector pin is controlled by a movable seat and a lifting module. Combined with the elastic deformation of the buffer head and auxiliary spring, the separation and buffering of the material stalk from the mold are achieved.

Benefits of technology

It effectively prevents the material shank from sticking to the mold ejector pin, ensuring that the material shank is smoothly ejected from the mold cavity, avoiding misalignment in subsequent processes, and facilitating the replacement of the buffer head, thereby improving production efficiency.
