AI Technical Summary
Traditional ball casting molds suffer from problems such as poor dimensional accuracy, uneven cooling rate, and difficulty in demolding, resulting in inconsistent product performance and difficult demolding operations.
A sand-coated casting mold was designed, which adopts an annular semi-circular groove and a flow channel structure, combined with an elastic ejector and a limiting clip, to achieve uniform solidification of molten metal and convenient demolding.
By optimizing the structure of the casting mold, we can ensure consistent solidification speed of the products, simplify the demolding process, and improve production efficiency and product consistency.
