[0002] Concrete centrifugal piles are formed by placing concrete into a mold, centrifuging it, and then steaming and curing it. Since concrete centrifugal piles have a large diameter and are long, the required molding mold also has the characteristics of being long and large in diameter. Generally, the molding mold consists of a bottom mold and an upper mold. After the bottom mold is filled with concrete, the upper mold is placed on it. The upper mold and the bottom mold are connected by several bolts. Both the bottom mold and the upper mold are made of iron and are heavy. They require large lifting equipment to transfer them. Moreover, one molding mold can only produce one specification of concrete centrifugal piles. When not in production, the molding mold requires a dedicated area for storage, which takes up a large amount of workshop space. Utility Model Content
