Abstract
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.
