Abstract
An arrangement for opening and closing mold halves of a blow mold is disclosed. The blow mold generally forms part of a stretching and blowing machine for blow-molding hollow bodies from thermoplastic plastics materials. The mold halves are coupled to driven rocker arms, which are driven by driving rocker arms of a four-link gear, the pivot of the four-link gear being disposed immediately at the end of the common pivotal axis of the mold halves. The driving rocker arm of the four-link gear is formed by cylinders, which are provided with cam tracks on their external curved surfaces in which rollers mounted on a sliding cam controller travel.
