Abstract

SE PRESENTA UN SISTEMA DE MOLDEADO A INYECCION MULTICAVIDAD CONTROLADO MEDIANTE VALVULAS QUE TIENE UN CONDUCTO ALARGADO A TRAVES DEL CUAL LA MEZCLA FUNDIDA PASA HASTA UN NUMERO DE BOQUILLAS PRECALENTADAS. UN MIEMBRO DE UNA VALVULA SE ASIENTA EN UNA ABERTURA A TRAVES DEL CONDUCTO EN ALINEAMIENTO CON CADA BOQUILLA. EL MIEMBRO DE LA VALVULA SE MANTIENE EN CONTACTO ENTRE LA PLANCHA DE RESPALDO Y LA CARA TRASERA DE CADA BOQUILLA. EL MIEMBRO DE LA VALVULA TIENE UN CONDUCTO PARA LA MEZCLA FUNDIDA CON DOS BRAZOS SUAVEMENTE CURVADOS QUE ESTAN CONECTADOS ENTRE EL PASO DE LA MEZCLA FUNDIDA EN EL CONDUCTO PRINCIPAL Y EL PASO DE LA MEZCLA FUNDIDA ALREDEDOR DEL MIEMBRO DE LA VALVULA. DICHO MIEMBRO SUMINISTRA UN CIERRE ESTANCO ALREDEDOR DEL MIEMBRO DE LA VALVULA RECIPROCO Y TIENE UNA PESTAÑA EXTERIOR QUE FORMA UN ESPACIO DE AIRE AISLANTE Y UNA CAMARA DE CONTENCION PARA LA MEZCLA FUNDIDA LA CUAL NO PUEDE ESCAPAR.
