Pure copper conductor casting sand mold for transformer

The invention relates to the field of pure copper conductor casting, in particular to a pure copper conductor casting sand mold for a transformer. The pure copper conductor casting sand mold for the transformer comprises a flask, a riser, pouring gates and a mold core, and is characterized in that the flask comprises an upper flask, a middle flask and a lower flask; a hole is formed in a casting,the top of the casting is placed upwards, and the upper flask is provided with the riser; the main pouring gate is arranged on one side parallel with the casting and annular secondary pouring gates are arranged on two parting surfaces correspondingly; the internal part of the mold core is of a T-shaped double-layer steel plate frame structure; a plurality of through holes are drilled in the steelplate; and the mold core is erected on the upper flask through two positioning rods and is suspended in the middle of a cavity. The outer surface of the mold core is wrapped with coke and molding sandsequentially. Compared wit
