Iron mold sand-lined casting process with core making function and sand-lined mold

The invention provides an iron mold sand-lined casting process with a core making function and a sand-lined mold. A shape mold comprises a mold bottom plate, the mold bottom plate comprises casting male molds, shape mold sand core head seats and shape mold sand core cavities, the two sides of the casting male molds are connected with the shape mold sand core head seats correspondingly, and shape mold sand core core-head cavities are formed in the two ends of the shape mold sand core cavities are respectively; an iron mold comprises a casting mold cavity, iron mold sand core mold cavities and iron mold sand core head seat mold cavities, iron mold sand core head mold cavities are formed in the two ends of the iron mold sand core mold cavities correspondingly, perforation holes are formed in the casting mold cavity and the iron mold sand core mold cavities correspondingly, a shape mold and the iron mold are in butt joint, so that precoated sand cavities are formed between the casting male molds and the casting mold cavity, and sand core cavities are formed between the shape mold sand core cavities and the iron mold sand core mold cavities. The iron mold precoated sand shape mold cavity and a sand core can be prepared at the same time, a core box manufacturing procedure is omitted, the mold cost is low, and the production efficiency is high.
