Abstract
The invention relates to a device for blow molding containers. The temperature of parisons, which are made of a thermoplastic material, is adjusted and the parisons are then molded in a blow mold under the effect of a pressurized medium to give containers. The blow mold which is composed of at least two blow mold segments is held in place by mold supports of a blow molding station (3) that is arranged on a supporting structure (41). A bottom part (7) is used in addition to the blow mold segments. Both the mold supports and the bottom part are arranged in such a way that they can be mechanically positioned. The mold supports and the bottom part are mechanically coupled to each other. One of the mold supports (19) is immobile and the other mold support is swiveled to the supporting structure. The bottom part has a trajectory relative to the mold support which has a component that extends in the longitudinal direction of the blow molding station and a component that extends at a right angle to the longitudinal direction.
