Abstract: Process for producing plastic containers, including an extrusion blow molding machine, is disclosed. For example, in an extrusion blow molding process for plastic bottles, in which plastic tubing (T) which has been extruded from an extruder head in a definable cycle is placed in the mold cavity of a blow molding tool arrangement, the inserted plastic tubing is inflated via an infeed blow mandrel by overpressure according to the mold cavity and is then removed from the mold. The extruded plastic tubing (T) is inserted into a mold cavity which is composed of several blow mold cavities which are located axially under one another, two of the blow mold cavities at a time being arranged mirror-symmetrically to one another and connected on their mouth regions and an individual blow mold cavity being separated from the bottom section of the adjacent blow mold cavity by a land region and having a mouth on the outer surface of the blow molding tool arrangement.

Abstract: The present invention is directed to a blow-molding device in terms of the mounting of its blowing and calibrating mandrels. With exemplary embodiments, the effort and expense for dismantling or changing the position of the blowing mandrels can be simplified. The clamping force for the blowing mandrels can be easily adjustable. In an exemplary embodiment, the relative position in terms of height of the blowing mandrels is not impaired by the clamping.
