Abstract
In an apparatus for shaping plastics material pre-forms into plastics material containers, the blow mould comprises a first mould part and a second mould part, the blow mould comprises a base part which is movable with respect to the mould parts along a lifting direction extending parallel to the longitudinal axis of the mould parts, in order to close off a cavity, in the closed setting, in the lifting direction, and wherein a plastics material pre-form is capable of being directly acted upon with pressure by a gaseous medium inside the cavity, wherein at least one second drive device which is designed in the form of an electric linear drive is set up and provided to move the base part relative to the mould parts in the lifting direction.
