Abstract

AL FABRICAR MOLDES CASI SECOS DE PLASTICO ESPUMADO TERMOPLASTICO SE MANTIENE UNA PRESION DE AIRE DURANTE EL CALENTAMIENTO DE LAS PIEZAS DEL MOLDE MEDIANTE VAPOR EN UNA CAMARA DE PRESION LLENA DE PARTICULAS DE PLASTICO PREVIAMENTE ESPUMADAS Y UNIDA CON UN ESPACIO HUECO DE MOLDE MEDIANTE APERTURAS DE PASO. ESTA PRESION ES IGUAL O MUY POCO MAYOR QUE LA PRESION DEL VAPOR UTILIZADO PARA EL CALENTAMIENTO. SI LA PARED DEL MOLDE HA LLEGADO A LA TEMPERATURA DEL VAPOR SATURADO, SE BAJA LA PRESION DE AIRE PARA SOLDAR LAS PARTICULAS DE PLASTICO ESPUMADAS Y POR EL VAPOR QUE ENTRA SE CALIENTAN LAS PARTICULAS DE PLASTICO A LA TEMPERATURA NECESARIA PARA LA SOLDADURA O EL SINTERIZADO. UN DISPOSITIVO (10) ADECUADO PARA LA REALIZACION DE ESTE PROCEDIMIENTO DEBE TENER POR LO MENOS UNA LINEA DE CONEXION (30) DEL ESPACIO HUECO DE MOLDE (17) A LA PARTE EXTERIOR DEL DISPOSITIVO DE ESPUMADO CON UNA LINEA DE SERVICIO (37) CONECTADA Y CONTROLADA POR UNA VALVULA CON EL FIN DE ASI INTRODUCIR EN EL ESPACIO HUECO DEL MOLDE AIRE COMPRIMIDO PARA CREAR UNA CONTRAPRESION O BIEN QUITAR VAPOR. POR LO MENOS UNA DE ESTAS LINEAS DE SERVICIO PUEDEN LLEVAR LOS DISPOSITIVOS (31) PARA LLENAR EL MOLDE
