ABSTRACT:
An injection unit (1) for injection molding machines used in the manufacture of plastic objects has a nozzle element (2), a material feed system (7), a cylinder-piston unit (3, 4) arranged between the nozzle element (2) and the material feed system (7), a valve (10) arranged between the cylinder (4) and the material feed system (7), and a device (21) for pressing the nozzle element (2) to the edge of the gate of an injection mold. The nozzle element (2), and the piston (3) guided in the cylinder (4), may be integrally formed. The nozzle element has a channel (11) in alignment with an axial bore (13) in the piston (3). The channel (11) and bore (13) are in communication with the interior of the cylinder. The cylinder (4) can be moved in the direction of the longitudinal axis of the piston while the piston (3) does not move.
