Summary:The invention relates to a casting device and a casting process. The casting device comprises a vibration platform, a sand box, evanescent molds, stone sand, a protection ring, sodium silicate sand, a thin film and a pouring cup. Casting molds are cast by adopting the evanescent modes, the casting quality of the casting molds can be improved, and the rejection rate of casting of the casting molds is reduced. A plurality of circular grooves are formed in one surface of each mold body, and the center distance between every two adjacent circular grooves ranges from 11 mm to 12.5 mm. The surface area of the mold bodies is fully utilized, and the utilization rate of the mold bodies is improved. Meanwhile, the area of connecting sheet-shaped connecting blocks between cast metal blocks is reduced, the utilization rate of molten steel is increased, and the yield of the metal blocks is also increased. The casting process comprises the steps of paint drying, evanescent mold placing, stone sand filling, vibrating, stone
