Casting method of valve body casting

The invention relates to a casting method for valve body castings. The casting method comprises the following steps that a casting mold is designed, two castings are designed in one mold, the castings are obliquely arranged, and the two castings in the casting mold are symmetrically arranged; the whole casting mold is in a cuboid shape and comprises a cover core, a first inner cavity core, a second inner cavity core and a bottom core, the top face of the bottom core is designed to be symmetrical and inclined, and the first inner cavity core and the second inner cavity core are symmetrically assembled on the inclined face of the bottom core. The cover core is provided with a dead head, and the bottom surface of the cover core is symmetrically and obliquely designed and assembled at the top of the 1 # inner cavity core and the top of the 2 # inner cavity core; and the pouring system adopts a low-side pouring open type pouring system. According to the casting method of the valve body type casting, the casting is
