Abstract
An apparatus is provided for the shaping of plastics material containers, with a movable carrier on which are arranged a plurality of shaping stations for the shaping of plastics material pre-forms into plastics material containers, wherein these shaping stations have blow mould carrier parts movable with respect to each other for opening and closing the shaping stations, and wherein the shaping stations have a locking mechanism for holding the shaping stations in a closed state.
Claims16
An apparatus for the shaping of plastics material containers, comprising:
- a rotating carrier on which are arranged a plurality of shaping stations for the shaping of plastics material pre-forms into plastics material containers;
- wherein these shaping stations have blow mould carrier parts movable with respect to each other for opening and closing the shaping stations;
- and wherein the shaping stations have a locking mechanism for holding the shaping stations in a closed state, and with an opening and closing mechanism for opening and closing the shaping stations;
- wherein the locking mechanism has a locking cam opposite which the shaping stations move at least in part, wherein this locking cam extends—as viewed in the direction of movement of the carrier continuously between a position in which the blow mould carrier parts are opened and a position in which the blow mould carrier parts are closed;
- and the blow mould carrier parts are held automatically in the closed state at least along a further partial section of the periphery by a locking means arranged on the blow mould carrier parts.
A method of shaping plastics material pre-forms into plastics material containers, comprising:
- conveying the plastics material pre-forms by means of shaping stations along a pre-set conveying path;
- shaping the pre-forms to form the plastics material containers during this conveying;
- wherein the shaping stations have blow mould carrier parts which are moveable with respect to each other by an opening and closing mechanism for closing the shaping stations;
- wherein the blow mould carrier parts are automatically held against each other by means of a locking mechanism at least for a time during the shaping procedure;
- and wherein from shortly after a beginning of an opening procedure until shortly before a conclusion of a closure procedure of the blow mould carrier parts, a cam follower of the locking mechanism constantly rests against an associated locking cam.
