Abstract

Système de coulée par gravité - pression avec coulée par gravité et solidification sous basse pression par l'effet de la gravité dans lequel la descente de coulée du moule comporte à sa base un étranglement de limitation de débit se raccordant à un réseau d'alimentation des empreintes des pièces et à une colonne donnant la pression désirée. Les sections des branches du réseau d'alimentation sont de massivités calorifiques adaptées aux pièces et progressives en partant des attaques de coulée vers la colonne de pression. Pour assurer une alimentation efficace les attaques de coulée sont placées sur les parties massives des pièces avec une section d'attaques suffisante. Les points les plus hauts des empreintes sont placés à un niveau inférieur au niveau de la partie haute de la colonne de pression d'une valeur correspondant à celle de la pression d'alimentation choisie.Gravity casting system - pressure with gravity casting and solidification under low pressure by the effect of gravity in which the casting descent of the mold has at its base a flow limiting constriction connecting to a supply network of impressions of the parts and a column giving the desired pressure. The sections of the branches of the supply network are of calorific massivities adapted to the parts and progressive starting from the casting attacks towards the pressure column. To ensure an efficient feed, the casting attacks are placed on the massive parts of the parts with a sufficient attack section. The highest points of the imprints are placed at a level lower than the level of the upper part of the pressure column by a value corresponding to that of the chosen supply pressure.
