Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a refractory coating spraying device for the surface of a white mold used in lost foam production. Background Art

[0002] The lost foam is a foam body. When pouring molten iron, the foam melts when heated, and the molten iron can be filled in the cavity where the lost foam is located. The lost foam is very soft and will deform when buried in the sand. Therefore, it is necessary to apply refractory coating on the outside of the lost foam to increase its hardness and surface finish.

[0003] The existing refractory coating processes for the white mold surface of the lost foam production are divided into manual coating and machine coating. Manual coating is to manually immerse the lost foam directly into the coating, and machine coating is to clamp the lost foam with a robot and immerse it into the coating. In fact, the above two methods cannot guarantee the coating thickness, so the error will become larger after the mold is formed. Secondly, the lost foam is pressed into the coating. The lost foam is light and has large buoyancy. Excessive pressure will cause the lost foam to deform partially, affecting the yield rate. Therefore, a refractory coating spraying device for the white mold surface of the lost foam production is proposed to solve the above problems. Utility Model Content
