Casting method of punch headstock casting

The invention relates to the technical field of casting, and provides a casting method of a punch machine head seat casting, the casting method of the punch machine head seat casting is realized through a casting device of the punch machine head seat casting, and the casting method of the punch machine head seat casting comprises the following specific steps that S1, a sand core raw material is guided into a sand core mold; uniformly filling a sand core raw material to form a sand mold corresponding to the punch headstock casting; s2, liquid metal obtained through smelting is poured into a sand mold, then a mold closing mechanism abuts against a sand core mold, and an initial casting is obtained after cooling; s3, the mold closing mechanism is completely separated from the sand core mold, and then the casting in the sand core mold is ejected out through the demolding mechanism; and S4, finally, the casting is taken out, the sand core raw materials attached to the surface of the casting are cleaned, and the fo
