Abstract
Dispositivo para moldear metal fundido para la produccion de piezas fundidas de metal por medio de la tecnologia "espuma perdida", que comprende: un primer recipiente (15) de metal fundido, un segundo recipiente (15) que tiene una boca superior y que contiene un bano de material granular (2), inmerso en este esta un modelo (3, 3a) hecho de material expandido que puede evaporarse cuando se pone en contacto con el metal fundido, y el medio surtidor (14) para suministrar el metal fundido desde el primer recipiente (15) hacia el modelo (3, 3a) en el segundo recipiente (1), y los medios para aplicar un vacio parcial al segundo recipiente (1), el medio comprende una cubierta movible (7) que puede sellar la boca del segundo recipiente (1) de manera hermetica y. la cual tiene una primera abertura (9) con la cual se asocian los medios que generan el vacio (10, 11) y una segunda abertura (13) con la cual se asocia el medio surtidor (14) de manera hermetica a fin de que, cuando se fija la cubierta (7) en el segundo recipiente (1) de manera hermetica y se activan los medios que generan el vacio (10, 11), se transfiere el metal liquido desde el primer recipiente (15) hacia el modelo (3, 3a).
