Nozzle tool system and extrusion blow molding arrangement

A nozzle tool system for extrusion blow molding, having an intermediate module (1) and at least a first nozzle outlet unit (2) and a second nozzle outlet unit (2), which units each form an adjustable nozzle outlet gap between a mandrel (9) that extends in an axial direction (x) and a deformable sleeve (8), which units can be connected with the intermediate module (1) as replacements for one another, and which units have a first outlet diameter and a larger second outlet diameter, which diameters are different from one another,

• wherein at least one setting drive (3) for reversible deformation of the sleeve (8) is arranged on the intermediate module (1) and can be connected with the deformable sleeve (8) by way of a releasable coupling arrangement,
• wherein the first nozzle outlet unit (2) delimits a first setting path of the setting drive (3) using at least one inner mechanical stop (12a), and the second nozzle outlet unit (2) delimits a second setting path, which is greater than the first setting path, of the setting drive (3), using at least one inner mechanical stop, and
• wherein the inner mechanical stops (12a) are spaced apart from the at least one setting drive (3) and are configured for a pressing setting movement of the at least one setting drive (3), by a contact surface, in each instance, of the corresponding nozzle outlet unit (2) so as to limit travel of the deformable sleeve (8).
