AI Technical Summary

Technical Problem

In existing technologies, resin sand tends to adhere to the inner wall of the mold, requiring manual cleaning of the sand when the mold is no longer in use, which reduces the efficiency of the mold.

Method used

An automated sand removal device for resin sand casting molds was designed. It uses a cylinder to drive the upper mold to separate from the lower mold, and combines an electric slide rail and a high-pressure nozzle to automatically blow away the resin sand through an air compressor and air delivery hose. It is equipped with a protective cover to prevent sand particles from splashing.

Benefits of technology

It achieves automatic cleaning inside the mold, improves sand removal efficiency, avoids the low efficiency of manual sand removal, and enhances cleanliness and stability.
