An injection-molding tool (1) for a clamping unit of an injection-molding machine for producing injection-molded parts, comprising a frame tool, consisting of a first, nozzle-side tool half (2) and a second, ejector-side tool half (3), is described. Mold insert halves (50, 51) of at least one mold insert (11) are fitted in slide-in frames (9, 10). The slide-in frames (9, 10) with the at least one mold insert (11) fitted in them can be connected to one another to form a slide-in module (8) which in the modifying process can be removed as a whole from the frame tool, which in the modifying process remains connected to the injection-molding machine.
