Abstract
EN UN CABEZAL DE INYECCION PARA LA FABRICACION DE CUERPOS DE FORMA DE VARIAS CAPAS CON UN NUCLEO DE POR EJEMPLO MATERIAL TERMOPLASTICO ESPUMADO Y UN REVESTIMIENTO EXTERIOR DE MATERIAL TERMOPLASTICO NO ESPUMADO, REDUCIENDO EL TRABAJO DE CONSTRUCCION, POR UNA PARTE DEBE ASEGURARSE QUE TAMBIEN LAS PIEZAS DE FORMA DE UN VOLUMEN RELATIVAMENTE GRANDE CON UNA NECESIDAD DE MATERIAL REDUCIDA, SE FABRIQUE CON SEGURIDAD Y ESTABLES.POR OTRA PARTE DEBE GARANTIZARSE QUE LA PROGRESION DE LOS CUERPOS FORMADOS DE PLASTICO A INYECCION PUEDAN EJERCERSE CON SEGURIDAD. UTILIZANDO UN CABEZAL DE INYECCION 1 EN EL QUE POR UNA PARTE MEDIANTE UNA CARCASA 4 CON UNA PIEAZA AXIAL 7 EN FORMA DE TUBO Y UNA TOBERA INTERIOR 13,14,15 PARA EL MATERIAL PLASTICO, QUE A SU VEZ CONTIENE UNA AGUJA CON DESPLAZAMIENTO AXIAL 9 COMO DISPOSITIVO DE CIERRE, Y EN EL CUAL EL OTRO MATERIAL PLASTICO ESTA FORMADO EN UNA ZONA CIRCULAR 6 ENTRE LA PIEZA DE TUBO 7 Y LA CARCASA 4 CON UNA TOBERA DE ANILLO 10,11, FORMADA POR LA PIEZA DE TUBO 7Y TENINDO UN CUELLO 18 EN LA TERMINACION LIBRE DE LA AGUJA DE CERRADO 9, QUE EN POSICION DE CIERRE DE LA TOBERA INTERIOR 13,14,15 POR LO MENOS CIERRA DE FORMA SUCINTA CON LA TERMINACION LIBRE DE LA PIEZA DE TUBO 7. SE CONSIGUE YA QUE LA AGUJA DE CERRADO 9 EN SU TERMINACION LIBRE 19 DISPONE DE UNA ABERTURA DE TOBERA 20 EN LA QUE HACIA ATRAS SE UNE UN CANAL DE UNION 22 QUE TIENE UNA ABERTURA RADIAL DE PERIMETRO 22. EN EL REVESTIMIENTO DE LA PIEZA DE TUBO 7 SE ENCUENTRA TAMBIEN UN CANAL DE UNION 24 LONGITUDINAL, QUE EN EL PERIMETRO INTERIOR 8 DE LA PIEZA DE TUBO 7 TIENE UNA SALIDA RADIAL 23. LA ABERTURA RADIAL 22 DE PERIMETRO DEL CANAL DE UNION 21 DE LA AGUJA DE CERRADO 9 PUEDE POSICIONARSE CON UNION DE CAUDAL CONECTADA Y DESCONECTADA CON LA SALIDA RADIAL 23 DEL CANAL DE UNION 24 EN LA PIEZA DE TUBO 7, POR LO MENOS EN LA POSICION DE CERRADO CORRESPONDIENTE A LA POSICION AXIAL DE LA GUJA DE CERRADO 9 MEDIANTE UN GIRO RELATIVO AL REDEDOR DEL EJE LONGITUDINAL CONJUNTO.
