Abstract
A toggle lever clamping unit for an injection molding machine includes fixed and movable platens, a support plate, a toggle lever mechanism operatively connected with both the support plate and the movable platen, a cross clamp operatively connected with the toggle lever mechanism and movable along a machine longitudinal axis, and an electric drive for moving the cross clamp. In addition, a hydraulic drive is operatively connected with the cross clamp and includes a fluid-operated piston cylinder system, with the lengths of the cylinder and the piston rod being coordinated with one another such that the hydraulic drive follows a travel path of the cross clamp as the movable platen travels between an open position of the clamping unit, in which the toggle lever mechanism is swung in, and a closed position in which the toggle lever mechanism assumes a predeterminable extended position and a clamping force is built up.
