[0019] Preparation before construction: Check the mold, conduct a comprehensive inspection of the assembled combination mold to ensure that all components are intact, without damage and deformation, clean the construction site, ensure that the construction area is flat and free of obstacles, and provide good basic conditions for the installation of the mold. Mold installation: When it is necessary to cast a cylinder, first use the external circuit mechanism to make the first motor 309 work, the first motor 309 drives the driving gear 305 to rotate, and meshes with the fan gear 306 for transmission, so that the two adjacent outer templates 1 change their angles to the outside through the first pin, wherein the first spring 3104 applies a force to the protective ring 3103, so that the driving gear 305 always meshes with the fan gear 306 for transmission, and at the same time, through the external control system, the electric push rod 404 works, and the electric push rod 404 pushes the adjacent outer templates 1 to change their angles through the third pin, so that the shape formed between the outer templates 1 is circular, and then the concrete is poured inside the enclosure 501 through external equipment.

Moreover, by providing the sealing plate 5014, when concrete is poured into the rectangular formwork, gas needs to be injected into the filling cavity to buffer the force exerted by the concrete on the enclosure 501. The sealing plate 5014 can prevent the gas in the filling cavity from leaking out and affecting the effect of the rectangular concrete pouring. The concrete's own weight exerts a force on the inner wall of the enclosure 501, so that the enclosure 501 is always in contact with the curved surface of the outer formwork 1, and the enclosure 501 is bent by the indentation surface 5011, thereby realizing the casting of a cylinder. When pouring the rectangle, Figure 1As shown, concrete is first poured inside the enclosure 501 through external equipment, and then the air pump 502 is operated through the external control system to fill the filling cavity with gas to buffer the force exerted by the concrete on the enclosure 501, thereby achieving a smooth side of the cast body.
