Abstract

UN METODO DE PRODUCIR TANQUES DE PLASTICO PARA LAVADORAS, COMPRENDIENDO UNA ESTRUCTURA RIGIDA (5) FORMADA POR UNA BANDA (6) CILINDRICA PERIFERICA Y LA PARED INFERIOR (7) CIRCULAR, Y UNA PARED FRONTAL (8) CIRCULAR REALIZADA SEPARADAMENTE, Y COMPRENDIENDO UNA PLURALIDAD DE BRAZOS (11) RADIALES HUECOS INTEGRALES CON LA PARED 87) Y ADAPTADO PARA CONTENER AIRE O GAS. EL METODO COMPRENDE UNA PRIMERA FASE EN LA QUE EL MATERIAL PLASTICO ES INYECTADO DENTRO DEL MOLDE PARA FORMAR EL TANQUE EN UNA CANTIDAD PARA QUE OCUPE PARCIALMENTE LA CAVIDAD INTERIOR DEL MOLDE; Y UNA SEGUNDA FASE EN LA QUE EL AIRE O GAS ES SOPLADO DENTRO DEL MATERIAL PLASTICO EN TAL FORMA QUE HINCHE LA MASA Y RELLENE LA CAVIDAD ENTERA DE LA MATRIZ, Y TAMBIEN FORMA LAS CAVIDADES INTERIORES (13) EN LOS BRAZOS RADIALES (11) EN LA QUE EL AIRE O GAS PERMANECEN ENCERRADOS. LOS TANQUES DE ESTE TIPO SON ESTRUCTURALMENTE RESISTENTES Y REALIZADOS CON UN BAJO CONSUMO DE MATERIAL.
