Abstract

The improvements are applicable to the production of cast steel parts (15), provided with inner cavities (16), by the arrangement of various stacked compartments (1,2,3,4,5,6), with a central filling collector (8) and multiple parts (7) disposed radially or in another form in each of the compartments and characterised in that in the end of the core (21,30) which corresponds to the inner cavity of each of the parts, there is a projection (20,22,23,24,26,27,28) for controlling a recess which is provided inside the part, in the area distant from the outer surface thereof, all of the filling being performed from the single central filling duct (8), without supply sinkheads. The projection for controlling the recess disposed inside the core provides communication of the cavity of the recess with the atmosphere, by means of its own core, owing to the permeability of the sand, avoiding local depressions in the walls of the cast part.
