The invention relates to an injection unit (1) of an injection molding machine which is arranged movable relatively to a machine base (2) of the injection molding machine in an axial direction (A), wherein the injection unit (1) comprises a base body (3) at which a screw cylinder (4) is arranged, wherein a screw (5) is arranged rotatable and axially movable in the screw cylinder (4), wherein the screw (5) is connected with a drive element (6) at one of its axial ends which can rotate the screw and can also move it in axial direction (A) and wherein the drive element (6) comprises a gear element (7) which is movable in axial direction (A) as well as an actuator (8) which is in engagement with the gear element (7) and with the base body (3) and which can perform a translational movement in axial direction (A). To obtain an elementary design which guarantees a high precision the invention is characterized in that the base body (3) is designed as a one-piece block which has a plate-shaped reception (9) for the screw cylinder (4) at one of its axial ends and has a plate-shaped reception (10) for the actuator (8) at its opposite axial end. |
