Abstract

UN SISTEMA DE MOLDEO POR INYECCION CON VALVULA DE COMPUERTA PARA FABRICAR PRODUCTOS DE PLASTICO HUECOS. UNA ESPIGA FIJA (66) SE PROLONGA A TRAVES DE UN MIEMBRO DE VALVULA HUECO ALARGADO (60) QUE TIENE UN MOVIMIENTO ALTERNATIVO ENTRE UNA POSICION ABIERTA RETRAIDA Y UNA POSICION CERRADA AVANZADA EN LA CUAL EL EXTREMO DELANTERO (64) DEL MIEMBRO DE VALVULA (60) SE ASIENTA EN LA COMPUERTA (18). LA ESPIGA FIJA (66) TIENE UNA PARTE HUECA (90) PARA QUE CIRCULE GAS A PRESION HACIA UNA PARTE POROSA DEL EXTREMO DELANTERO (68), QUE ESTA EMPLAZADO CENTRALMENTE CON RESPECTO A LA COMPUERTA (18). EN LA POSICION ABIERTA, EL GAS PROCEDENTE DE LA ESPIGA FIJA CIRCULA HACIA EL CENTRO HUECO (134) DE UNA CORRIENTE DE MASA FUNDIDA (130) QUE FLUYE HACIA DENTRO DE LA CAVIDAD (20) QUE CIRCUNDA AL EXTREMO DELANTERO (68) DE LA ESPIGA FIJA (66), PARA FORMAR UNA BURBUJA DE MASA FUNDIDA (136) EN LA CAVIDAD (20).
