Abstract

UN SISTEMA DE MOLDEO POR INYECCION CON VALVULAS DE COMPUERTA DE VARIAS CAVIDADES. EL MECANISMO ACCIONADOR NEUMATICO QUE PRESTA UN MOVIMIENTO ALTERNATIVO A LOS MIEMBROS DE VALVULA ALARGADOS INCLUYE UN EMBOLO QUE SE MUEVE ALTERNATIVAMENTE EN UNA ABERTURA CILINDRICA A TRAVES DE UNA PLACA CILINDRICA. UN CASQUILLO DE CIERRE HERMETICO MONTADO ALREDEDOR DE CADA MIEMBRO DE VALVULA TIENE UNA PARTE DE PESTAÑA QUE HACE PUENTE CON UNA SEPARACION DE AIRE AISLANTE ENTRE EL COLECTOR Y LA PLACA DE CILINDRO. DE ESTA MANERA, EL CASQUILLO DE CIERRE HERMETICO FORMA PARTE DEL CILINDRO DE EMBOLO ADEMAS DE CREAR UN CIERRE HERMETICO CONTRA FUGAS DE MATERIA FUNDIDA ALREDEDOR DEL MIEMBRO DE VALVULA DE MOVIMIENTO ALTERNATIVO. EL EMBOLO TIENE UNA BANDA EXTERIOR CIRCUNFERENCIAL, FORMADA CON UNA ALEACION DE GRAFITO, ALOJADA EN UNA GARGANTA FORMADA ENTRE UNA PARTE DELANTERA Y UNA PARTE DE PLACA POSTERIOR EXTRAIBLE.
