[0038] The two mounting holes 512 are respectively mounted on the two second support rods 33 , and then the pressing assembly 3 is lifted to the top of the sand pool 11 . The pressing plate 31 is controlled to descend by starting the hydraulic rod 57 , so that the lake sand in the sand pool 11 is compacted.
[0039] The lake sand in the sand pool 11 is demoulded to form a sand mold, and the operation is as follows:
[0040] By respectively putting the two mounting holes 512 on the two first support rods 14, the skeleton is lifted by contracting the hydraulic rod 57, and the lake sand in the sand pool 11 is brought out to form a sand mold. By starting the third motor 510, the sand mold can be controlled to flip, so that the two sand molds can be merged conveniently.
