| 摘要 |
The invention relates to a clamping device for an injection molding machine for plastics, including a fixed platen (11) which is connected to a moving platen (12) by means of a toggle mechanism (13). A hollow-shaft motor (7) is provided to cooperate with a spindle (21) for operating the toggle mechanism, wherein the hollow-shaft motor (7) is connected to the toggle mechanism (13). According to the invention, the spindle (21) is arranged in a rotationally fixed manner, the end of the spindle (21), facing the moving platen (12), is in engagement with the rotor (6) of the hollow-shaft motor (7), and the stator (4) of the hollow-shaft motor is connected with the toggle mechanism (13). Preferably, a spindle nut is fixed in the rotor (6) for engagement with the spindle (21), preferably in the form of a recirculating ball screw.
