Title
(EN) NOZZLE WITH REMOVABLE NOZZLE TIP CONFIGURED FOR IMPROVED HEATING
(FR) BUSE AVEC POINTE DE BUSE AMOVIBLE CONFIGURÉE POUR UN CHAUFFAGE AMÉLIORÉ
Abstract
(EN)
The present application describes injection molding machines and, more particularly, a removable nozzle tip and nozzle assembly for use with an injection molding machine and an engagement tool and methods for replacing a nozzle tip. In an aspect, an injection molding machine may include a nozzle. The nozzle may include a nozzle housing and a nozzle tip threadably attached to the nozzle housing. At least a portion of an exterior wall of the nozzle housing and at least a portion of an exterior wall of the nozzle tip may align to provide a cylindrical surface. The injection molding machine may further include a tubular heater enclosing at least a portion of the continuous cylindrical surface. The nozzle tip does not include a torque feature in any location that is downstream of the tubular heater and upstream of a mold gate of the nozzle.
(FR)
La présente invention concerne des machines de moulage par injection et, plus particulièrement, une pointe de buse amovible et un ensemble buse destinés à être utilisés avec une machine de moulage par injection et un outil de prise et des méthodes pour remplacer une pointe de buse. Selon un aspect, une machine de moulage par injection peut comprendre une buse. La buse peut comprendre un boîtier de buse et une pointe de buse fixée par filetage au boîtier de buse. Au moins une partie d'une paroi extérieure du boîtier de buse et au moins une partie d'une paroi extérieure de la pointe de buse peuvent s'aligner pour fournir une surface cylindrique. La machine de moulage par injection peut en outre comprendre un élément chauffant tubulaire entourant au moins une partie de la surface cylindrique continue. La pointe de buse ne comprend pas de caractéristique de couple dans n'importe quel emplacement qui est en aval de l'élément chauffant tubulaire et en amont d'une entrée de moule de la buse.
