Description

Multi-angle uniform sand spraying device for casting machining Technical Field The utility model relates to the technical field of casting processing, in particular to a multi-angle uniform sand spraying device for casting processing. Background Castings are shaped articles of metal obtained by various casting methods. Castings have a long history of use. Cast parts are used by ancient people as well as some living appliances. Recently, castings are mainly used as blanks of machine parts, some precision castings can also be directly used as machine parts, and the castings have a large specific gravity in mechanical products. The casting is manufactured by firstly manufacturing a wax mould according to the shape of the required casting, then manufacturing a sand shell matched with the shape of the wax mould on the surface of the wax mould by utilizing sand spraying equipment, after the sand shell is air-dried, melting wax by utilizing wax melting equipment, then pouring liquid metal into the sand shell, and cooling to manufacture the casting.
