Apparatus for the shaping of plastics material pre-forms into plastics material containers with magnetically actuated locking

摘要

An apparatus is provided for the shaping of plastic pre-forms into containers with at least one blow moulding station arranged on a movable carrier, and having a blow mould carrier, a first blow mould carrier part and a second blow mould carrier part which is pivotable relative to the first blow mould carrier part to open and close the blow mould. The blow moulding station additionally has a locking mechanism to lock the first blow mould carrier part with respect to the second blow mould carrier part, and the locking mechanism has a first locking element on the first blow mould carrier part, and a second locking element on the second blow mould carrier part, for locking the carrier parts. A first magnetic element is movable relative to the first locking element and causes a movement of the first locking element by a magnetic interaction to lock the carrier parts.
