Abstract: The invention relates to an arrangement and to a method for the electromechanical drive for mold closing systems and calibration blow mandrel systems in blow molding machines, wherein the arrangement for the drive of an extrusion blow molding machine includes a push mechanism (3; 11), a push rod (4; 12) and exactly one electric motor (1; 9), wherein the push rod (4; 12) is movable by the push mechanism (3; 11) which is driven by the electric motor (1; 9), wherein the electric motor (1; 9) has an additional braking device (2; 10) which can be activated on the reaching of a required torque or a required force of the electric motor (2; 10) to hold the push rod (4; 12) in a state of maximum tension in its instantaneous position.
