The invention provides a sand mixing device for casting. The sand mixing device comprises a machine box body, a sand mixing bin, a feeding device and a driving system, wherein the driving system is arranged at the bottom of the machine box body, and the sand mixing bin and the machine box body are connected through the feeding device; and a filtering layer is arranged in the machine box body and divides the machine box body into a stirring cavity A and a stirring cavity B; the stirring cavity A serves as a rough stirring area, the stirring cavity B serves as a fine stirring area, and the mixing uniformity is improved through stirring by areas; and the stirring cavity A is in a funnel shape, the stirring cavity B is cylindrical, and the central axis of the stirring cavity A is perpendicular to the central axis of the stirring cavity B. According to the design purpose, the sand mixing device can conveniently move and be filled with sand through the driving device, no large-scale sand conveying and casting equipment is needed to be arranged in a workshop, and therefore the equipment cost can be reduced, and the sand mixing uniformity can be improved by stirring equipment; and meanwhile, the sand mixing device has the advantages that the sand can be fed and mixed continuously, and therefore the efficiency of casting and mixing the sand can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of casting, in particular to a sand mixing device for casting. Background technique [0002] The sand mixer is a device that uniformly mixes the components in the molding sand and effectively coats the binder on the surface of the sand grains. The sand mixer is a device that uniformly mixes the components in the molding sand and effectively coats the binder on the surface of the sand grains. Sand mixer is a kind of sand processing equipment widely used in the foundry industry. According to the characteristics of sand mixing process, sand mixer can be divided into: roller type sand mixer mainly for rolling and rubbing; Blade-type sand mixer with main function; countercurrent or rotor-type sand mixer with rubbing and mixing functions, and balance wheel sand mixer with rolling and mixing functions. The sand mixer in the prior art is usually fixed at the construction and casting site. If the sand is used up, i...
