Technical Field

[0001] The utility model relates to the technical field of concrete molding, and more specifically, to a demoulding device for prefabricated concrete components. Background Art

[0002] At present, when preparing precast concrete blocks, special molding molds need to be customized according to their sizes so that they can solidify and form. However, in order to improve the structural strength, traditional molding molds have a multi-in-one molding structure. Forcible removal is also prone to damage to the side of the concrete due to viscosity and static friction resistance. Therefore, a demoulding device for precast concrete components is needed.

Therefore, in view of the above problems, a demoulding device for precast concrete components is proposed. Utility Model Content
