Abstract
UN SISTEMA O APARATO DE MOLDEO POR INYECCION DE CAVIDADES MULTIPLES CON UNA CAJA (90) DE RESORTE Y SELLADO COLOCADA ENTRE CADA TOBERA (10) Y EL DISTRIBUIDOR (12). CADA TOBERA (10) OSCILA ENTRE UNA POSICION ABIERTA RETRAIDA Y UNA POSICION CERRADA HACIA DELANTE EN EL QUE EL EXTREMO ANTERIOR AHUSADO (32) SE ASIENTA EN UNA SALIDA (40). LA TOBERA (10) TIENE UNA ZONA DE MANGA CENTRAL (36) CON UN DIAMETRO INTERIOR (58) QUE SE PROYECTA HACIA ATRAS DENTRO DE UN HUECO DE ADAPTACION TALADRADO EN LA CAJA. LOS MUELLES DE DISCO (106), COLOCADOS EN UN CANAL (102) EN LA CAJA QUE SE EXTIENDE ALREDEDOR DE LA ZONA DE MANGA (36) DE LA TOBERA (10), POLARIZAN LA TOBERA HACIA LA POSICION CERRADA. ASI, DURANTE CADA CICLO LA PRESION DE INYECCION CONDUCE CADA TOBERA (10) A LA POSICION ABIERTA RETRAIDA, Y LUEGO LA POLARIZACION DEL MUELLE LA CONDUCE HACIA LA POSICION CERRADA ANTERIOR CUANDO SE LIBERA LA PRESION DE INYECCION. LA CAJA DE MUELLE Y SELLADO (90) EVITA EL ESCAPE Y DESALINEAMIENTO CUANDO OSCILA LA TOBERA.
