ABSTRACT OF THE DISCLOSURE A quick changing and/or quick gripping device for the molding tools of injection molding machines. The two mold halves of each molding tool are alignable in insertion guides between two adapter plates located opposite each other. The adapter plates are movable toward each for closing the molding tool and are movable apart from each other for opening the molding tool. The mold halves can be fixed in their aligned position by means of clamping members. During the changing and/or gripping procedure, the two mold halves of the closed molding tool are fixedly locked or coupled to each other. At least one locking bar is movably mounted in a mold half and automatically engages a locking bar engagement member mounted in the other mold half by means of a biasing force, such as, a spring. The locking bar includes an actuating element which projects into the range of an intermediate plate of the respective mold half, the intermediate plate being capable of being operatively connected to the clamping members. At least one of the clamping members, when moved into its clamping position, is movable against the actuating element of the locking bar and the locking bar can thus be forcibly disengaged relative to the locking bar engagement member.
