摘要

Machine for the centrifugal molding of metal parts, especially for jewelry and costume jewelery, characterized essentially by the fact of presenting a rotating platform driven by an electric motor through a device that reduces and conveniently varies its speed, whose platform is located inside a box sealed by means of an upper cover, this turntable having the suitable means for the assembly and settling of special molds of vulcanized rubber, which are provided with a central deposit in which it is poured, before its close, the metal casting in sufficient state of fluids, whose mass, when starting the rotating platform and thanks to the centrifugal force developed in the mold, is distributed to the different peripheral cavities that make up the matrices of the pieces, distribution that is effected by shifting said mass through radial ducts of communication between those and the central deposit, giving rise to molded pieces of surface perfectly polished and devoid of porosities.
