US 8,100,688 B2 · Device for blow molding containers

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.

Dependent claims

A device for blow molding containers, which has at least one blowing station mounted on a support structure for blow molding thermoplastic preforms into containers;

in which the blowing station is provided with at least two blow mold segments that are supported by mold supports and with a base part;
and in which both the mold supports and the base part are arranged in a way that allows them to be mechanically positioned, and the mold supports and the base part are mechanically coupled with one another, wherein one of the mold supports (19, 20) is mounted by the support structure (41) in an immovable way, while the other mold support (19, 20) is mounted by the support structure (41) in a way that allows it to swivel, where the base part (7) is mounted in a way that allows it to move relative to each of the two mold supports (19, 20), and where the base part (7) has a path of motion relative to the mold supports (19, 20) that has both a component that extends in the longitudinal direction (43) of the blowing station (7) and a component that extends perpendicularly to the longitudinal direction (43).
