The invention relates to a sand mold hoisting structure which comprises a hoisting rod device and a connecting plate. The hoisting rod device comprises a first hoisting rod and a second hoisting rod which are perpendicularly connected, wherein a mounting hole is formed in one side of a sand mold and located at the edge position of the sand mold, a sand shakeout hole communicated with the mounting hole is formed in the other side of the sand mold. The connecting plate is rotationally arranged in the mounting hole, a through groove is formed in the connecting plate, and a positioning groove intersecting with the through groove is formed in the side, facing the sand shakeout hole, of the connecting plate. The second hoisting rod extends into the mounting hole and penetrates through the through groove, and under the condition that the first hoisting rod is rotated, the second hoisting rod can be positioned in the positioning groove in a matched manner. According to the scheme, the problem that in the prior art, the sand mold hoisting effect is poor can be solved.
