Mold for molding cylindrical specimen of concrete or mortar strength test, characterized by the process of stripping the compressed air

摘要

"Mould for moulding the body of evidence cilu00ecndrico concrete or mortar strength test, characterized by the process of stripping the compressed air.The present invention relates to a cylinder mould in plastic, PVC or polyethylene, without the use of movable parts, butterflies or screws existing in the conventional way.It also innovates the demoulding process of the body of evidence in this case is done with the aid of compressed air, providing the advantages of less weight, higher precision of dimensions.Greater ease in desmolde and cleaning as well as improved ease of handling and transport.This mold can be composed of two parts, cylinder (1) and the base (2), sympathetic to each other by glue or solder (4) or in a single piece plastic injected.The base has in the center a hole (3) which is injected into the compressed air.
