Description

Technical Field

[0001] The utility model relates to the technical field of mold casting, in particular to a casting sand cleaning device for mold casting. Background Art

[0002] After the casting is cooled and shaped, the operator takes the casting out of the mold. A lot of sand and soil will remain on the surface of the casting, so it needs to be cleaned. When the operator cleans the surface of the casting, there are mainly dry cleaning and wet cleaning. Dry cleaning is to clean it through a shot blasting machine. This cleaning method will leave sand and soil in the shot blasting machine when the casting is cleaned, causing secondary cleaning of the inside of the shot blasting machine. The wet cleaning method is to clean the sand with water and flush the sand and soil on the surface of the casting by water washing. However, when cleaning, the casting is generally placed on a cleaning rack for washing. This cleaning requires manual flipping of the casting. The overall operation is labor-intensive and the cleaning efficiency is low. Therefore, a sand cleaning device for mold casting with improved sand cleaning efficiency is designed.
