Abstract: A tool for injection molding plastic parts includes a static overall frame and two structural units for forming a cavity. One of the structural units is arranged displaceably relative to the overall frame and the other structural unit in order to remove an injection-molded part from the cavity. The static overall frame is formed by at least two frame units, in particular a first ejector-side tool element and a second nozzle-side tool element, which are displaceable relative to one another, but in the production mode are displaceable within the scope of the elasticity, which is preferably less than a millimeter.
