A sand core hoisting device is used for hoisting sand cores or mud cores. The device comprises two beams, two straight-pulling rib units, two inclined-pulling rib units, a hook, two rotor seats, two rotors and an angle adjuster matched with the rotors. The beams are arranged in a spaced mode, the straight-pulling rib units are connected with the two ends of the beams respectively, one end of each inclined-pulling rib unit is pivoted to the corresponding straight-pulling rib unit, and the other end is connected with the hook. The rotor seats are connected with the corresponding straight-pulling rib units, and the rotors are pivoted to the corresponding rotor seats. By means of the sand core hoisting device, the sand core or mud core surface quality is improved, and the hoisting, cleaning, application and assembly efficiency for small-batch manual production of sand cores or mud cores is improved.
