The invention discloses a quadruple valve body casting. The quadruple valve body casting comprises a valve body, a transverse flow channel, longitudinal flow channels and flow channel ports, the valvebody is in a cuboid shape, the longitudinal flow channels comprises the first longitudinal flow channels and the second longitudinal flow channels, the first longitudinal flow channels and the secondlongitudinal flow channels are of tubular structures, and a cavity is vertically arranged above the second longitudinal flow channels, and openings are formed in the lower end of the cavity. The invention further discloses a quadruple valve body casting mold. The mold comprises a shell mold and a sand core, the sand core is formed by assembling a main sand core body and a plurality of small sandcore bodies, the main sand core body is formed by assembling a plurality of sand core main bodies, graphite core iron is placed in the main sand core body, air exhaust holes are formed in the two ends of the main sand core body, and the air exhaust holes communicate with a small sand core hole and a main sand core hole. The interiors of flow channels of the quadruple valve body casting are smooth, moreover, the flow channels in the casting is free of seams, and the sand core does not crack; and the casted casting is smooth in appearance and free of pore defect, and the qualified rate of castings is 95% or more.
