When the column cylinder is produced, the outer mold and the inner mold are put down together and placed on the bottom mold, then concrete is poured into the inner cavity of the outer mold, and then the upper top mold is pressed down to compact the concrete and press the concrete into the column cylinder of the enclosing wall. Compared with the traditional mode of pouring after adopting the formwork, the fixed die is adopted for pouring and pressing forming, the hardening time of the product can be better shortened, the processing efficiency of the product is improved, the structural strength of the product is increased, and the enclosure column cylinder body with a complex inner cavity structure can be conveniently processed.

Further, the internal mold comprises a first mold core which is positioned at the middle part and has a larger rectangular cross section, four second mold cores which are positioned at the outer sides of the periphery of the first mold core, the long side length of the first mold core is consistent with the side length of the first mold core, the internal mold further comprises four third mold cores which are positioned at the outer sides of four corners of the first mold core, the side length of the first mold core is consistent with the side length of the short side of the second mold core, and the connecting plate is connected between the adjacent first mold cores, second mold cores, third mold cores and the inner side of the outside.
Thus, the fence column cylinder body with the outer cylinder body, the inner cylinder body with the inner part forming a groined shape and the connecting ribs can be processed. Specifically, the structure of the inner cylinder of the wall column cylinder is formed in the space between the first mold core and the second mold core, the structure of the connecting rib of the inner cylinder of the wall column cylinder is formed in the space between the second mold core and the third mold core, and the structure of the outer cylinder of the wall column cylinder is formed between the second mold core and the third mold core and the inner side surface of the outer mold.
