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).

摘要： The invention relates broadly to injection molding machines and more particularly to a novel barrel assembly for use in an injection unit of an injection molding machine. Barrels are conventionally mounted at an end in a carriage of an injection unit. Axial carriage force is directed along the entire length of the barrel which requires a thick barrel wall to withstand the axial carriage force. A barrel assembly is disclosed having a first barrel coupler (46) and a second barrel coupler (60). The first barrel coupler secures the barrel intermediate the ends of the barrel to a carriage. The second barrel coupler retains an end of the barrel in the carriage preventing rotation of the barrel during operation. The barrel section between the first barrel coupler and an end of the barrel is isolated from axial carriage force in operation.

摘要： A plasticizing unit for an injection moulding machine has a cylindrical barrel (1) with a cylindrical screw (4) movable axially and rotatably in it. The unit has an inlet (2) for material, a compression zone, a plasticizing zone (5, 6), and a cylindrical reservoir chamber for plasticized material, which is ejected into the mould by axial movement of the screw (4). The plasticizing zone (5, 6) is of the Transfermix type, where the cross section of the helical groove of the screw (4) varies from full area to zero area and the cross section of a corresponding groove in the barrel (1) varies from zero area to full area so that the material is transferred to the barrel groove, and a return zone (7) after the plasticizing zone (5, 6) returns the material to the reservoir chamber. The screw (4) has a part (9), where its helical groove is of zero area, which acts as a piston in the reservoir chamber for the injection action.
