Abstract

The invention provides a precoated sand mixer which has a reasonable structure, can be regulated according to different site requirements, is universal, can be used for mixing sand continuously and uniformly, and has high production efficiency. The precoated sand mixer comprises a machine base and a sand mixing mechanism, wherein the sand mixing mechanism comprises a sand stirring cage, a sand transporting and stirring cage, and a driving device for driving the sand stirring cage and the sand transporting and stirring cage, the sand stirring cage and the sand transporting and stirring cage are respectively provided with a sand inlet and a sand outlet, and the sand stirring cage is respectively provided with a resin feed valve and a curing agent feed valve. The precoated sand mixer is characterized in that the sand transporting and stirring cage is connected with the machine base by virtue of a pivoting support, the sand outlet of the sand transporting and stirring cage is connected with the sand inlet of the sand stirring cage by virtue of the pivoting support, and an operation handrail is arranged at the front end of the sand stirring cage.

Description

technical field [0001] The invention relates to the technical field of coated sand production equipment, in particular to a coated sand mixer. Background technique [0002] Coated sand, the surface of the sand grains is covered with a layer of solid resin film or core before molding. The coated sand mainly uses high-quality selected natural quartz sand as the original sand, and adds thermoplastic phenolic resin, curing agent, lubricant and reinforcing agent. etc. as raw materials. Coated sand molding is used in complex castings with high dimensional accuracy requirements. It is one of the best molding materials for automobiles, tractors, hydraulic parts, etc. With the development of domestic and foreign machinery industries, especially the automobile industry, the quality requirements for castings are getting higher and higher. High, the application of mold coating sand is more and more extensive. [0003] The sand mixer is an important equipment in the production of coate...
