Molding system of thermal insulation composite pipe

The forming system of the heat preservation composite pipe relates to the technical field of composite pipe machining and comprises a bottom plate, a machining barrel with the top open is arranged in the middle of the top face of the bottom plate, a base is detachably connected to the bottom of the machining barrel, and a supporting ring is fixedly connected to the top of the base. A supporting ring is arranged on the bottom plate, a through hole is formed in the edge of the supporting ring, an inner cylinder is detachably connected to the top of the supporting ring, a feeding area is formed by the bottom of the inner cylinder and the inner side of the supporting ring, a forming area is formed by the outer side of the inner cylinder and the inner wall of the bottom plate, and an insertion hole is formed in the middle of the inner cylinder. The composite pipe molding device is reasonable in structure, heated composite pipe raw materials are injected into the molding area through the material filling assembly t
