Abstract

DISPOSITIVO DE INYECCION DE MATERIAL EN MAQUINAS PARA FABRICAR MOLDES DE FUNDICION MEDIANTE MOLDEO. CONSISTE EN UN CABEZAL DE INYECCION (33) QUE RECIBE EL MATERIAL DE MOLDEO (71) DE UNA TOLVA (31), ALIMENTADA POR UNA MEZCLADORA ROTATORIA, EN CANTIDAD DETERMINADA, QUEDANDO LA VALVULA DE MARIPOSA (42) CERRADA, UNA VEZ ADMITIDO AQUEL. ESTA PROVISTO DE UNAS ENTRADAS DE AIRE COMPRIMIDO POR LA VALVULA (43) Y LA CAMARA FLUIDIFICANTE (45), Y EL DISTRIBUIDOR (56) A LAS CAVIDADES (15, 16) DEL MOLDE, HACIENDOLO A GRAN VELOCIDAD, YA QUE EL AREA DE SALIDA DEL RESTRICTOR ES EL 10 POR 100 DE LA DE ENTRADA, LOGRANDOSE EL LLENADO RAPIDO DEL MOLDE, ANTES DEL ENDURECIMIENTO DEL MATERIAL. ESTA PROVISTO DE DISPOSITIVO DESVIADOR PARA RETIRAR EL EXCESO DE MATERIAL QUE NO PASA DE UN 0,5 POR 100 DEL NECESARIO PARA EL MOLDE.
