Casting core box mold with low-pressure pouring system

The invention relates to the technical field of casting, in particular to a casting core box mold with a low-pressure pouring system. The core box is composed of a left half mold and a right half mold, the core box is vertically placed on the bottom plate, the left half mold and the right half mold are the same in structure, the opposite faces of the left half mold and the right half mold are provided with concave cavities, the opposite faces of the left half mold and the right half mold are attached, the cavities of the left half mold and the right half mold are combined to form a filling chamber, the side face of the core box is provided with a flange opening, and the flange opening is communicated with the filling chamber. The flange opening is formed by combining a left half mold and a right half mold, and a filling opening is formed in the top of the core box; and the casting channel is arranged in the core box. Due to the fact that the mold core formed by the core box is matched with the outer mold for
