Description

technical field

[0001] The invention relates to the technical field of mold casting, in particular to a multi-head glue spraying device for sand mold casting. Background technique

[0002] Sand casting is a casting method that produces castings in sand molds: fill the sand box with sand with sand molds, inject molten metal into the sand mold through the sprue cup, and form castings after the molten metal cools in the sand mold. The sand box is usually divided into an upper sand box and a lower sand box. When the upper sand box and the lower sand box are combined, the openings of the upper sand box and the lower sand box are combined to form a closed cavity. Before injecting molten metal into the sand mold, it is necessary to apply glue to the inner wall of the sand mold. One is to smooth the surface of the inner wall of the sand mold, eliminate the grooves on the inner wall of the sand mold, and improve the quality of the casting. The second is to prevent metal castings afte...
