Abstract
DISPOSITIVO PARA ELIMINAR LA PARTE DE MAZORRA AL FINAL DEL MOLDEO POR INTECCION. COMPRENDE UN OBTURADOR PARA EL CANAL DE ALINEACION DE MATERIAL TERMOPLASTICO FUNDIDO QUE CIERRA EL CANAL DESPUES DE SER EMPUJADO A CONTACTO CON LA SUPERFICIE DEL ARTICULO. CON ELLO LA MAZAROTA DEBIDA AL CANAL DE ALIMENTACION ES SEPARADA EN EL CONTORNO DEL ARTICULO CUANDO EL MATERIAL QUE ACABA DE SER INYECTADO ESTA TODAVIA EN ESTADO PASTOSO POR NO HABER EXPERIMIENTADO AUN EL PROCESO DE ENFRIAMIENTO.
