Abstract

SE DESCRIBE UNA HERRAMIENTA PARA LA COLADA DE UNA TAPADERA DE PLASTICO POR INYECCION EN EL TUBO DE UN ENVASE PARA LIQUIDOS. LA HERRAMIENTA TIENE UN MOLDE INTERNO Y UNO EXTERNO DE DOS PARTES (2,7), EN LAS CUALES PUEDEN ENCAJAR HERMETICAMENTE O SEPARARSE DOS PIEZAS CONFORMADAS DE ACERO (2,7) A LO LARGO DE UN TABIQUE DE SEPARACION (12) POR MEDIO DE UN ACCIONAMIENTO. LA CAVIDAD DE MOLDEO POR INYECCION ESTA FORMADA POR UN CONJUNTO DE PERFILES SUPERFICIALES (17) ACOPLADOS SOBRE LOS MOLDES (2,7). EN EL LADO CONTRARIO A LA CAVIDAD DE MOLDEO, DETRAS DEL CONJUNTO DE PERFILES (17) HAY UNOS ESPACIOS DE REFRIGERACION (19). CON OBJETO DE MEJORAR EL RENDIMIENTO DE LA MAQUINA PRODUCTORA DE ENVASES, MEJORANDO EN PARTICULAR LA REFRIGERACION DE LA SUPERFICIE DE MOLDEO, EL INVENTO HA PREVISTO QUE LOS ESPACIOS DE REFRIGERACION (19) LIMITEN, AL MENOS POR UN LADO, CON UNA PIEZA INTERCALADA (9,11) EN UNA ESCOTADURA (20) EN LA CORRESPONDIENTE PIEZA (2,7), DE MODO IMPERMEABLE A LOS LIQUIDOS.
