[0024] The present invention operates on the following principle: The moving frame 64 moves the square vertical guide rail 68 to a designated position. Then, the second power device motor 613 drives the sprocket group 614 to rotate, and the transmission chain 610 drives the inner support mechanism 67 to move downward. The inner support mechanism 67 moves downward and extends into the interior of the inner mold, causing the hydraulic cylinder 672 in the inner support mechanism 67 to drive the bottom fixing member 6711 to move downward. This causes the connecting rod 673 to unfold and drive the elastic partition 674 to be fixed to the inner side wall of the inner mold. This allows the inner mold cement pipe to move together to the designated position. Then, the hydraulic cylinder 672 drives the bottom fixing member 6711 to move upward, causing the connecting rod 673 to retract. This causes the elastic partition 674 to loosen the inner side wall of the inner mold, realizing the hoisting and transfer.

[0025] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
