Problems solved by technology

And existing sand mold spraying device is carrying out spraying to sand mold inner cavity, what adopt is to utilize the spraying frame that a plurality of spraying heads are installed to carry out spraying to sand mold inner cavity, and what spraying heads usually adopt is static setting, The spraying range is small, the spraying surface is small, resulting in low work efficiency, and the sprayed colloid is more concentrated and difficult to disperse, making local glue application insufficient, and there are dead spots for glue application, which is prone to uneven glue application.

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...
