Zusammenfassung:PURPOSE: A turnover sand mold gravity casting method and its device are provided to improve the quality of a cast product and a working speed. CONSTITUTION: An injecting cup(20) is inserted in an inlet of a pouring gate(14). Melted liquid is injected to the injecting cup through an injecting ladle(22). The melted liquid is injected into the pouring gate without leaking. A scrapper(24) is installed in an injecting face of a sand mold(12). Dregs of the melted liquid are removed by the scrapper(24) by flowing the sand mold through a conveyer(26). The inlet of the pouring gate(14) is sealed by a pouring gate sealer(28). The sand mold(12) is inverted by an inverter(30). In sufficiently hardening a cast material inside the sand mold(12), the cast material is separated from the sand mold. Thereby, a cylinder block is produced.
