摘要:
A device for molding plastic preforms into plastic containers may include at least one blow station having a first mold part and a second mold part. The first mold part and the second mold part surround a cavity within which the plastic preforms may be expanded into plastic containers. The first mold part may be movable relative to the second mold part. The device includes a first cantilever which is disposed on the first mold part, a second cantilever which is disposed on the second mold part, a first hinge lever which is hingedly connected to the first cantilever, and a second hinge lever which is hingedly connected to the second cantilever. The first cantilever and the second cantilever may be arranged to be pivotable with regard to at least one geometrical pivot axis and may be coupled to an actuating device which causes a movement of the first cantilever and of the second cantilever for moving the mold parts. The blow station may be mounted on a transport via a carrier. The carrier may extend through a geometrical plane which is delimited by the cantilevers and the hinge levers and/or the geometrical arrangement of the cantilevers and the hinge levers may be arranged to be asymmetrical with regard to a geometrical center line of the blow station.
