This utility model belongs to the field of automotive parts, specifically relating to a sand core weight reduction structure applied to a low-pressure cavity subframe. It includes a sand core body and a cover. The thicker portion of the sand core body is hollowed out to form a concave structure. A step, approximately the same thickness as the cover, is provided at the upper end of the concave structure to accommodate the thin-walled cover. When the sand core body and the sand core cover are combined, the outer surface forms the interior required for the casting, and the interior forms a box-shaped cavity weight reduction structure. This reduces the amount of core sand used, lowers the labor intensity of operators during handling, and improves the efficiency of subsequent sand removal, thus enhancing the sand removal effect.
