The invention provides a precoated sand-casting sand box. The precoated sand-casting sand box comprises a box body, a transmission mechanism, a sand outlet, baffles and a clearing mechanism. The precoated sand can be cleared out of the box body through the sand outlet; the clearing mechanism can be driven by the transmission mechanism to clear the inner wall around the box body; manual work is reduced; and time and labor are saved. Due to the arrangement of the second baffle, the problem can be prevented that the precoated sand splashes in the process that clearing blocks clear the inner wall of the box body; due to the design of the transmission mechanism, the four clearing blocks can do horizontal reciprocating movement along the inner wall of the box body; the clearing blocks do vertical reciprocating movement under the action of a second reciprocating lead screw, and the clearing efficiency can be improved due to the combination of the horizontal reciprocating movement and the vertical reciprocating movem
