Mold closing unit for an injection molding machine

Mold closing unit for an injection molding machine for processing plastics materials and other plasticizable materials such as ceramics and powdered materials, comprising

• at least one machine bed,
• at least one stationary mold mounting plate arranged on the machine bed,
• at least one movable mold mounting plate arranged on the at least one machine bed movable relative to the at least one stationary mold mounting plate, wherein the at least one movable mold mounting plate is movable on a carriage with guideway shoes along at least one guideway that is mounted on the at least one machine bed with the at least one stationary mold mounting plate into and out of closure of an injection mold arrangeable in a mold clamping space,
• at least one drive mechanism for moving the at least one movable mold mounting plate and for opening/closing the mold closing unit, wherein the at least one drive mechanism has at least one toothed rack drive driven by at least one drive motor with at least one gearwheel and at least one toothed rack cooperating therewith,
• wherein at least two toothed racks are fixedly connected to the at least one machine bed and
• wherein the at least one drive motor is fixedly connected to the carriage and during a movement of the at least one movable mold mounting plate moves synchronously with the at least one movable mold mounting plate in the same direction,
• wherein the carriage comprises at least one load sensor for detecting tilting forces, the at least one load sensor being connected to at least one regulating unit, which is adapted to regulate the at least one drive mechanism according to the tilting force.
