Description

Technical Field

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] Sand cleaning machine is a device for cleaning the molding sand on the surface of the molded casting. Generally, small castings and casting runners (cylindrical shells, such as motor shells) are manually cleaned on the spot with iron hooks and hand hammers, which are difficult to control, have poor sand cleaning effects and low efficiency, and are labor-intensive. In addition, the dust and molding sand particles generated by them are easily splashed and cause harm to workers. Since the inner surface of the casting runner usually has sand particles that are difficult to remove, they are directly backfilled into the melting furnace for melting, resulting in a large amount of slag in the solution, which reduces product quality, increases the load of the melting furnace, and increases energy consumption.
