Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a quick demoulding mold for prefabricated concrete components. Background Art

[0002] Precast concrete components are building components made in factories in advance using concrete as the basic material, including beams, slabs, columns and building decoration accessories. The production of precast concrete components is generally done by pouring concrete into molds, demoulding and removing the components after the concrete is formed.

[0003] The demoulding process of the mold mainly uses a rubber hammer to knock on the outer wall of the mold until the prefabricated part is loosened from the mold, and then the mold is disassembled. Due to the heavy weight of the prefabricated part and the mold, and the large number of fitting surfaces between the prefabricated part and the inner wall of the mold, the method of effectively knocking on multiple sides over a large area to demould has the disadvantage of low demoulding efficiency. In addition, during the demoulding process, improper operation by personnel may easily cause the surface of the concrete prefabricated part to be broken and chipped. In addition, after the various mold templates are completely disassembled, the subsequent casting of the prefabricated components needs to be repositioned and assembled, and the positioning and assembly operations of each template are more difficult due to the large and heavy templates.

[0004] Therefore, a quick demoulding mold for precast concrete components is needed to solve the problems in the prior art of low demoulding efficiency by effectively knocking and demoulding on multiple sides over a large area, and large-area knocking and demoulding causes a greater risk of damage to the precast components.
