Abstract

UN PROCESO PARA LA PRODUCCION DE OBJETOS HUECOS (1) DE MATERIAL TERMOPLASTICO, QUE CONSTA DE UNA PRIMERA FASE EN DONDE DOS LAMINAS CALENTADAS, ABLANDADAS (22, 23) DE MATERIAL TERMOPLASTICO SE INSERTAN, UNA ENCIMA DE LA OTRA, ENTRE LAS DOS MITADES DE UN MOLDE (11, 12) QUE TIENE UNA SERIE DE CAVIDADES (16) CONECTADAS POR CANALES (18); UNA SEGUNDA FASE EN DONDE SE INSERTA UN TUBO DE SUMINISTRO DE LIQUIDO DE MOLDEO (25) ENTRE LAS DOS LAMINAS (22, 23); Y UNA TERCERA FASE EN DONDE SE CIERRAN LAS MITADES DE LOS MOLDES (11, 12), LAS LAMINAS (22, 23) SE UNEN POR MEDIO DE CALOR, Y EL LIQUIDO PRESURIZADO ES SUMINISTRADO POR EL TUBO (25) PARA EL MOLDEO DE LAS LAMINAS (22, 23) EN EL INTERIOR DE LAS CAVIDADES (16) Y FORMANDO UN OBJETO (1) QUE TIENE UN NUMERO DE PARTES HUECAS (7). UN LIQUIDO SOLIDIFICABLE PUEDE INYECTARSE EN EL INTERIOR DE LAS CAVIDADES DEL OBJETO (1), QUE PUEDE CONSTAR DE UNA PLATAFORMA (1) U OTROS ELEMENTOS QUE TENGAN PARTES HUECAS, COMO EL SALPICADERO DE UN VEHICULO, LA ESTRUCTURA DE SOPORTE DE CARGA DEL ASIENTO DE UN VEHICULO, UN ELEMENTO DE INSONORIZACION DE UN VEHICULO, EL SOPORTE DE CARGA DE UN VEHICULO, EL MALETERO, UNA SEÑAL DE TRAFICO, UN INDICADOR DE BORDILLOS, UN ELEMENTO DE MADERA DE FORMA LIBRE, O UNA PLATAFORMA PARA UNA MAQUINA HERRAMIENTA.
