The invention relates to an injection molding machine comprising a movable die mounting plate (6), a fixed die mounting plate (2), a fixed support plate (5), and a locking unit (7) having a drive element (9), preferably driven parallel to the feeding direction (Z) of the movable mounting plate (6), for initiating an actuating force in the locking unit (7), and having a control arm assembly (12) connected to the drive element (9) in a jointed manner between the support plate (5) and the movable mounting plate (6) and a design of the control arm assembly (12) having three control arms (13, 14, 15) coupled in a jointed manner, namely auxiliary control arm (13), central control arm (14) and output control arm (15) between the central control arm (14) and the movable mounting plate (6), such that the jointed axle (18) between the central (14) and output control arm (15) runs on a non-circular movement track (B), and that, in a closed position of the movable mounting plate (6), the four jointed axles (16, 17, 18, 19) of the control arm assembly (12) formed between the support plate (5), the control arms (13, 14, 15) and the movable mounting plate (6) lie on a straight line (G) which stands perpendicular on a turning point tangent (T) on the movement track (B) of the jointed axle (18) between the central (14) and output control arm (15). |
