Abstract (en)

A mould for stratified moulding with metalostatic pressure compensation formed by one or more stackable moulds formed by a tapping cavity of a generally rhomboidal truncated cone shape and one or more moulding cavities connected to the tapping cavity by one or more supply conduits; in such a way that each tapping cavity of each stackable mould interconnects to form a central filling collector, and each tapping cavity compensates for the metalostatic pressure of the molten metal as it is drained by the central filling collector to achieve generally uniform filling of each of the moulding cavities of each of the stackable moulds. In addition, the generally rhomboidal double truncated cone shape serves to keep a temperature distribution in the mould during the pouring of molten metal.
