Abstract
A mold closure system for machines processing plastics material, such as blow molding and injection molding machines, includes an essentially U-shaped pedestal having two legs and cross ties connecting them at one of their ends as well as two mold carriers and holding or supporting respectively one mold half, which are disposed between the two free legs of the pedestal 2 so as to be mobile against each other. When the molding tool is closed, the two mold carriers are provided with their abutments at the legs. A special guiding arrangement also is present for guiding the mold carriers parallel to one another to carry their weight. The guidance arrangement includes at least one guide beam or support, parallel to the direction of motion of the mold carrier, wherein the mold carrier are supported upon the guide beam or support to be longitudinally mobile.
