Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO PARA LA FABRICACION DISCONTINUA DE MOLDES PREVIOS DE VARIAS CAPAS EXTRUIDOS EN FORMA DE TUBO DE MATERIAL TERMOPLASTICO PARA FORMAR CUERPOS HUECOS DE GRANDES VOLUMENES DE VARIAS CAPAS DENTRO DE UN MOLDE DE SOPLADO PARTIDO, EN EL QUE POR LO MENOS DOS DIFERENTES CALDOS DE MATERIAL EN FORMA DE ANILLO SE JUNTAN EN EL CENTRO DENTRO DE LA CAMARA ANULAR Y EN SENTIDO DE LA EXTRUSION A UN CALDO DE MATERIAL DE VARIAS CAPAS Y EN EL QUE ESTE CALDO DE MATERIAL DE VARIAS CAPAS FLUYE EN EL ESPACIO DE ALMACENAMIENTO EN FORMA DE ANILLO Y DESPUES SE EMPUJA HACIA ARRIBA POR UNA CAMARA ANULAR MOVIL EN SENTIDO AXIAL QUE ACTUA DE CABEZA DE COEXTRUSION Y POR EL CALDO DE MATERIAL DE VARIAS CAPAS Y SE EXPULSA POR UNA RANURA DE TOBERA ANULAR DE FORMA QUE LOS DIFERENTES CALDOS DE MATERIAL ANTES DE ENTRAR EN LA CABEZA DE COEXTRUSION SE DESVIAN DE SU DIRECCION DE EXTRUSION Y ENTRAN RADIALMENTE EN LOS CANALES DE FLUJO CORRESPONDIENTES. CON EL FIN DE MEJORAR EL PROCEDIMIENTO CONOCIDO DE FORMA QUE EN LA ZONA DE TRANSMISION ENTRE EL EXTRUSOR CORRESPONDIENTE Y LA CAMARA ANULAR NO SE PRESENTEN MODIFICACIONES DE SECCION DE FORMA QUE SE EVITAN PUNTOS DEBILES O SE REDUCEN TANTO QUE YA NO TIENEN EFECTOS NEGATIVOS SOBRE EL CUERPO HUECO TERMINADO, SE PROPONE QUE LOS DIFERENTES CALDOS DE MATERIAL SE DESVIAN ANTES DE ENTRAR EN LA CABEZA DE COEXTRUSION, DE SU DIRECCION DE EXTRUSION Y QUE ENTREN RADIALMENTE EN LOS CANALES CORRESPONDIENTES DE FLUYO DE LA CAMARA ANULAR.
