INJECTION DEVICE AND METHOD OF HEATING INJECTION DEVICE

摘要

An induction-type heating device is installed in that region next to a cooling device which is on the outer periphery of a heating cylinder. This enables the temperature of the heating cylinder to be uniform and at an appropriate value, and enables the temperature of the heating cylinder to be quickly varied. An injection device intermittently sending forward a resin received in a heating cylinder (11) by a screw (12) in correspondence with a cycle of injection molding. The injection device has a cooling device (23) installed at the rear section of the heating cylinder (11) and an induction heating device (21) installed at a position more forward than the cooling device (23) on the heating cylinder (11) so as to be next to the cooling device (23).
