Abstract

METODO PARA MOLDEO CONTINUO POR INYECCION, DE HOJAS TRIDIMENSIONALES DE MATERIAL TERMOPLASTICO. COMPRENDE: A) INTRODUCIR CONTINUAMENTE MATERIAL TERMOPLASTICO FUNDIDO EN UNA RANURA DE UN TROQUEL DE EXTRUSION, PROXIMA A LA SUPERFICIE CURVA DE UN MOLDE GIRATORIO CON MUCHAS CAVIDADES. B) APLICAR EL MATERIAL TERMOPLASTICO PRESION SUFICIENTE SUPERIOR A 35 KG/CM2 PARA INYECTAR MATERIAL EN DICHAS CAVIDADES. C) MANTENER LA CARA CURVA DEL TROQUEL DE EXTRUSION PARA QUE EL INTERVALO ENTRE DICHO TAMBOR Y EL BORDE DELANTERO DE LA SUPERFICIE DEL TROQUEL DE EXTRUSION, SEA SUPERIOR AL INTERVALO POSTERIOR ENTRE DICHO TAMBOR Y EL BORDE POSTERIOR DE LA SUPERFICIE DEL TROQUEL DE EXTRUSION ADYACENTE A DICHA RANURA, Y UN SOPORTE UNIFORME PARA EL MOLDEADO TRIDIMENSIONAL SE TOMA POR EXTRUSION ENTRE DICHO BORDE POSTERIOR Y EL TAMBOR; CON LO QUE SE TOMA UN PRODUCTO TRIDIMENSIONAL CON SALIENTES QUE SE EXTIENDEN A PARTIR DE UN LADO DE LA SUPERFICIE PLANA. D) REFRIGERAR EL PRODUCTO HASTA SOLIDIFICARLO. E) RETIRAR DE LASUPERFICIE DEL MOLDE EL PRODUCTO TRIDIMENSIONAL SOLIDIFICADO.
