Abstract (en)
The invention concerned relates to a mould for casting sanitary appliances (15) with internal projecting parts, comprising separate mould parts (1,2,3,4) which, together with one or more mould pieces, are (5,6) designed to constitute a hollow or solid casting portion in the article cast in the mould, which also comprises, for each of said separate parts, at least one rotatable member (7) housed in a convenient seat in said one or more mould pieces, its free end extending until it practically reaches the zone of contact between the corresponding mould piece and the relative separate part, where it is provided with one of the two parts of a magnetic locking system (9), this latter part being eccentric and, when the corresponding rotatable member is in two opposing angular positions, becomes aligned with and disposed laterally to the other part of the magnetic locking system, this latter part being embedded in said corresponding separate part, so as to respectively couple together and uncouple the corresponding mould piece and the relative separate part.
