Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE PIEZAS FUNDIDAS DE HIERRO MEDIANTE MOLDES METALICOS INCORPORANDO UN SISTEMA DE VACIO, CONSISTE LA INVENCION EN DOTAR A LA INSTALACION DE UNAS TOBERAS DE SALIDA DE AIRE CONECTADAS CON UNA CANALIZACION, A PARTIR DE LAS CUALES SE CONSIGUE EL VACIO EN EL INTERIOR DEL MOLDE PENETRANDO EL CALDO POR LA EMBOCADURA SITUADA EN LA PARTE SUPERIOR, PARANDOSE DE FORMA AUTOMATICA LA INTRODUCCION DE CALDO CUANDO LA CAVIDAD SE ENCUENTRA LLENA, ESTANDO EL MOLDE DOTADO DE UN CIERRE HERMETICO DURANTE SU LLENADO, CERRANDOSE Y SUJETANDOSE MEDIANTE UNA PRESION EJERCIDA HACIA LA PARTE SUPERIOR SUMINISTRADA POR CILINDROS HIDRAULICOS COLOCADOS EN LA PARTE INFERIOR, PASANDO POSTERIORMENTE UN TIEMPO PREDETERMINADO PARA ASEGURAR LA SOLIDIFICACION Y ABRIENDOSE EL MOLDE A CONTINUACION MEDIANTE UN SISTEMA MECANICO DE EXPULSION, ASEGURANDO QUE LA PIEZA SE SEPARA SIMULTANEAMENTE DEL PROPIO MOLDE, REALIZANDO POSTERIORMENTE LA ACCION DE VACIO DE FORMA INVERTIDA Y APLICANDOSE AIRE EN EL INTERIOR DEL MOLDE.
