Description

Technical Field

[0001] The utility model relates to a demoulding machine for small prefabricated concrete components, belonging to the technical field of prefabricated concrete components. Background Art

[0002] Small precast concrete components refer to precast concrete components with smaller volumes, which are often used in fields such as railway construction. During the production process of small components, the concrete placing machine pours concrete into a cavity mold, which is then cured and solidified. After a series of process finished product inspections are passed, the mold needs to be removed. In general, the conventional practice is to first release the fixed parts between the steel beam and the side mold, and then use the chain hook of a manual hoist to hook the opening on the mold rib plate and pull it outward to loosen and separate the mold from the edge of the PC component. However, in actual situations, due to the difference in the bonding force between the mold and the edge of the PC component at different points, partial separation is incomplete during demoulding. It is necessary to repeatedly adjust the hook hole position of the chain hook and pull it multiple times to completely demould, which is inefficient. Utility Model Content
