ABSTRACT:
This device is used for the blow moulding of thermoplastic synthetic material, with it having a blow mould consisting of at least two blow-moulding elements. The blow mould is provided with an internal space designed for shaping a produced container. The blow moulding elements are arranged in the region of pivotally seated mould carriers. The mould carriers are guided on a shaft and a locking device is provided in the area of the end of the mould carrier facing away from the shaft. In the region of their extension facing away from the locking device, the mould carriers project beyond the shaft by means of their actuating arms. The actuating arms are rotationally coupled to an adjusting element via coupling levers. The adjusting element is guided essentially in the direction of a center line of the blow mould.
