Abstract

The invention relates to the field of casting techniques, and discloses a thin-wall housing type casting, and a moulding production line and a method of the thin-wall housing type casting. The moulding production line comprises a first conveying belt and a second conveying belt that are arranged side by side. The moulding production line further comprises a box closing machine, a casting machine, a first moulding machine for manufacturing a drag box, a second moulding machine for manufacturing a top flask, a plurality of first core-making machines for manufacturing side cores, and a second core-making machine for manufacturing a prefabricated sand core, wherein each of the first moulding machine, the second moulding machine and the first core-making machine takes green sand as a material, and the second core-making machine takes resin-bonded sand or precoated sand as a material. The moulding production line is low in manufacturing cost, a combination technology is simple and the function performance is reliable.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a thin-walled shell casting, a molding production line and a method thereof. Background technique [0002] For the production of sand cores for various thin-walled shell castings, selecting suitable molding materials and adopting the best combination design structure are important goals to meet product manufacturing structure requirements, reduce core material costs, and ensure casting molding quality. The molding materials that are conventionally used to make thin-walled shell molds, in order to reduce the cost of core making and meet the strength requirements of complex structures, usually use wet film sand and resin sand (coated sand) respectively. Green mold sand is mainly used For making upper and lower molds with relatively simple structures, resin sand is used to make sand cores around the sides of castings and in the inner cavity of castings. The casting sand mold made b...
