Abstract
The utility model relates to the technical field of impeller machining, in particular to an impeller casting sand mold. The sand mold is provided with an outer mold and an inner mold. A casting cavity is arranged between the outer mold and the inner mold. A step-shaped trumpet-shaped opening is formed in the top of one end of the casting cavity. A casting opening is arranged in the top of the step-shaped trumpet-shaped opening, and the other end of the casting cavity is T-shaped. The impeller casting sand mold is reasonable and novel in structural design; and before casting, paraffin wax in the casting cavity is removed at a high temperature, then casting molding is carried out, operation is easy and convenient, and molding effects are good.
