Integral slope sand box structure for wind power main frame

The utility model provides an integral slope sand box structure for a wind power main frame, which belongs to the technical field of casting and comprises a lower sand box and an upper sand box, a joint surface formed after the lower sand box and the upper sand box are combined up and down forms a parting surface, the lower sand box comprises a lower box and a lower sand mold, and the upper sand box comprises an upper box and an upper sand mold. The combined surfaces of the lower sand box and the upper sand box are inclined surfaces which are matched with each other, namely, the combined surfaces of the lower sand mold and the upper sand mold are inclined surfaces which are matched with a casting, the corresponding upper surface of the lower box is an inclined surface which is flush with the upper surface of the lower sand mold, and the corresponding lower surface of the upper box is an inclined surface which is flush with the lower surface of the upper sand mold. The combined surface of the upper box and the
