A device for closing molds of an injection molding machine for plastic having a main axis, comprising:
- a stationary end plate;
- a mold clamping plate;
- a plurality of traverses mounted to said stationary end plate and extending toward said mold clamping plate, said mold clamping plate being displaceably guided along said traverses;
- a double toggle lever, having a central portion, a first end connected to said stationary end plate and a second end connected to said mold clamping plate;
- a crosshead;
- and
- at least two drive units, between said end plate and said mold clamping plate, connected to said crosshead and mounted at said end plate and having an axis of displacement parallel to the main axis of the machine, said drive units being linked in form locked manner via said crosshead to said central portion of said double toggle lever for lever movement of said central portion with respect to said end plate such that said mold clamping plate is displaced along said traverses.
