Abstract

The invention provides a large-scale precoated sand mixing machine. The large-scale precoated sand mixing machine has the advantages of reasonable structure, large sand mixing quantity, low energy consumption, convenience in maintenance, high sand mixing efficiency and good quality. The large-scale precoated sand mixing machine comprises a stander, wherein a base is arranged on the stander, a sand mixing cylinder is mounted at the base, a sand mixing mechanism is arranged in the sand mixing cylinder and is connected with a speed reducer mounted at the lower part of the stander, the speed reducer is connected with a motor mounted on one side of the stander, an air inlet is formed in the base and is connected with a fan mounted on a fan frame by virtue of a flexible pipe, a sand feeding hole and a sand discharging hole are formed in the sand mixing cylinder, a top cover is mounted at the upper end of the sand mixing cylinder, and a resin inlet, a curing agent inlet and an air outlet are respectively formed in the top cover.

Description

technical field [0001] The invention relates to the technical field of coated sand production equipment, in particular to a large-scale 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 pro...
