AI Technical Summary

Technical Problem

In existing sand casting, the length of the embedded positioning sleeve is fixed, resulting in the need to replace different embedded positioning sleeves with different heights of sand or sand cores. The reinforcement ribs of the embedded positioning sleeve are easily damaged during the sand drop process, which increases the casting cost.

Method used

A sand casting box positioning device is designed, including a box body, a lower box sleeve, an upper box sleeve, a sleeve and a positioning pin. Through a slidable sleeve and a conical positioning pin, it is suitable for sand types and sand cores of different heights, avoiding damage to the reinforcement ribs during the sand drop process and reducing costs.

Benefits of technology

It realizes a positioning device that is not easy to damage when sand is falling, and is suitable for sand shapes and sand cores of different heights, reducing the cost of sand shape casting.
