[0047] In order to realize the movement of the first transfer trolley 5 along the predetermined track, the present application further includes a first roller conveyor 10 laid longitudinally, and the first transfer trolley 5 moves along the first roller conveyor 10; Figure 1As shown, the first roller 10 is located between the flow coating preparation station 401 and the outlet of the demolding machine 3, and at the same time between the flow coating completion station 402 and the sand mixing preparation station 201. It can not only receive the sand mold after demolding by the demolding machine 3, but also serve as a transfer station to transfer the sand core to the flow coating preparation station 401, and also take into account the transfer function between the mold, sand core, sand mold and the first stereoscopic warehouse 1.

[0048] Furthermore, in order to better layout the molding circle and ensure that there is sufficient space between each device or station, the sand mixing preparation station 201 and the flow coating completion station 402 are located on the same horizontal line; the sand mixing completion station 202, the outlet of the demoulding machine 3, and the flow coating preparation station 401 are located on the same horizontal line.

[0049] In addition, in order to facilitate the lifting and transfer of the sand mold or sand core after the surface is dried, a lifting part 11 is also included. The lifting part 11 is located on the side of the second lifting roller car 8 away from the first stereoscopic warehouse 1.
