Abstract

An device for molding plastic preforms into plastic containers comprises at least one blow mold and a plurality of closure members interacting with one another in order to transfer the blow mold between an open state and a closed state. The blow mold forms a cavity, within which the plastic preforms may be expanded into the plastic containers. The closure members comprise at least one first mold part and one second mold part, which are moveable with respect to one another. The closure members further comprise a blow nozzle unit which is moveable with respect to the mold parts, and which closes the blow mold in the closed state in one direction. At least one first drive unit moves the mold parts with respect to one another. A second drive unit moves the blow nozzle unit with respect to the mold parts. At least one drive unit moving at least one of the closure members for transferring the blow mold between the closed state and the open state includes an electric drive unit.
