Blow extrusion molding apparatus for producing plastic containers, and method for producing plastic bottles

摘要

blow molding device for producing plastic containers, and method for producing plastic bottles is proposed a blow molding device (1) for producing plastic containers, particularly plastic bottles, including an extruder head (3). ) which is connected to at least one extruder (2) for plastics material and has at least one extrusion die (4), a blow molding tool arrangement (5) having at least one blow molding cavity (6) and has at least one injection device (7) which is disposed on the side of the blow molding tool arrangement (5) facing outwardly from the extruder head (3) and which can be inserted in. from the blow molding cavity (6) through the opening provided therein. During a production cycle, such extruder head (3) can be axially adjusted in terms of its height relative to the blow molding tool arrangement (5). To this end, the extruder (2) is pivoted along its longitudinal extension about an axis of rotation (9), and can be tilted in the manner of a rocker, and the extruder (2) is configured such that the The height of the rotary axis (9) can be adjusted. In this way, for the production of plastic containers having a high height, a new starting position for the inclination of the extruder (2) can be established whereby the extruder (2) to include the rotary axis (9) thereof. , is high.
