Abstract
SE PRESENTA UN APARATO DE MOLDEADO, COMPUESTO (10) Y UN METODO PARA EL MOLDEADO A ALTA PRESION DE ARTICULOS COMPUESTOS DE NUCLEO EN FORMA DE PANAL, DE BAJO PESO QUE TENGAN SUPERFICIES INCLINADAS UTILIZANDO NUCLEOS EN FORMA DE PANAL, INCLINADOS, ESTABILIZADOS, DE BAJA DENSIDAD TOTAL. EL NUCLEO EN FORMA DE PANAL, INCLINADO, ESTABILIZADO, DE BAJA DENSIDAD TOTAL SE FORMA MEDIANTE UNA RED DE MATERIALES DE NUCLEO EN FORMA DE PANAL, ESTABILIZADOS, CONFORMADOS QUE SE DISPONE PARA SUPERPONERSE Y ENDURECERSE CONJUNTAMENTE MEDIANTE LA APLICACION DE UNA CAPA DE UN ADHESIVO EN FORMA DE PELICULA DE BAJO PESO A LAS SUPERFICIES SUPERIOR, INFERIOR E INCLINADAS DEL ARTICULO. EL MATERIAL DE NUCLEO EN FORMA DE PANAL SE ESTABILIZA PARA LA OPERACION DE CONFORMACION EN FORMA DE RED MEDIANTE UNA CAPA DE ADHESIVO EN FORMA DE PELICULA DE BAJO PESO APLICADA A LA SUPERFICIE SUPERIOR E INFERIOR DEL MATERIAL EN UN FORMATO DE MARCO DE CUADRO PREDETERMINADO. EL APARATO DE MOLDEADO COMPUESTO ES UN DISPOSITIVO DE MOLDEADO SEMIRRIGIDO QUE INCLUYE UN MIEMBRO DE BASE RIGIDO (12) Y UN MIEMBRO DE MOLDE COMPLEMENTARIO (20) SEMIRRIGIDO QUE INCLUYE PIEZAS DE INSERCION DE REFUERZO, RIGIDAS, INTERNAS (22) QUE SUMINISTRAN UNA DISTRIBUCION DE PRESION SIMETRICA SOBRE LAS SUPERFICIES INCLINADAS DEL NUCLEO EN FORMA DE PANAL DURANTE EL PROCESO DE CO-ENDURECIMIENTO DE ALTA PRESION. EL NUCLEO EN FORMA DE PANAL, INCLINADO SE HACE DESCANSAR SOBRE EL DISPOSITIVO DE MOLDEADO SEMIRRIGIDO, QUE SE ABOLSA MEDIANTE VACIO Y SE DISPONE EN UN AUTOCLAVE. LA BOLSA DE VACIO SE EVACUA, Y EL DISPOSITIVO DE MOLDEADO SE EXPONE A UN CICLO DE TEMPERATURA Y PRESION DE DOS ETAPAS PARA EL CO-ENDURECIMIENTO A ALTA PRESION. EL AUTOCLAVE SE PRESURIZA HASTA UNA PRESION DE RESIDENCIA, Y ENTONCES SE ELEVA LA TEMPERATURA DESDE UNA TEMPERATURA AMBIENTE HASTA UNA TEMPERATURA DE RESIDENCIA DESPUES DE LO CUAL EL AUTOCLAVE SE ESTABILIZA DURANTE UN PERIODO DE RESIDENCIA. DESPUES, LA PRESION DEL AUTOCLAVE SE INCREMENTA HASTA UNA ALTA PRESION, Y LA TEMPERATURA SE ELEVA HASTA UNA TEMPERATURA DE COENDURECIMIENTO DESPUES DE LO CUAL EL AUTOCLAVE SE ESTABILIZA UN PERIODO DE CO-ENDURECIMIENTO PARA EFECTUAR EL ENDURECIMIENTO DEL ARTICULO. DESPUES DE QUE SE HAYA COMPLETADO EL ENDURECIMIENTO, EL AUTOCLAVE SE ENFRIA, Y LUEGO SE DESPRESURIZA PARA SEPARAR EL APARATO DE MOLDEADO COMPUESTO.
