Abstract

A blow molding tool (1) for producing a plastic article, in particular a fuel tank, comprising at least one clamping frame (2) with mold clamping devices (3) and at least two blow mold halves, which are formed such that they can be moved together and apart by means of an opening and closing movement of the clamping frame (2) and which respectively have at least one cavity (8) for the forming of the plastic article, the blow molding tool (1) being distinguished by the fact that the mold clamping devices (3) respectively have at least one tool holder (6), in which a mold insert (7) is in each case exchangeably inserted, and in that the tool holders (6) respectively form a peripheral sealing edge (10).
