A drive-reversing safety mechanism using a pivotable contact ledge on the leading edge of a mechanically openable and closable safety gate of an injection molding machine, the pivot axis being arranged at a flange corner of the safety gate, where the channel-shaped contact ledge engages the outside of the corner with a fillet of a ledge fold. An adjacent positioning flange of the contact ledge is yieldingly clamped to the safety gate by means of pins and compression springs. An actuator plate attached to the contact ledge cooperates with a switch controlling the safety gate drive.
