Abstract
A pair of mating mold halves are mounted between upper and lower clamp plates 25, 22. The lower clamp plate is driven by a hydraulic unit 17 mounted to a base plate 16, which is rotatably disposed on a tiltable table plate 7. The upper clamp plate is journaled between the arms 26, 28 of a yoke pivotally mounted on the base plate and controlled by hydraulic units 29 coupled between the yoke arms and the upper clamp plate. This compact multi-pivotal arrangement affords a large separation stroke between the two clamp plates without, by reason of the lateral pivoting of the yoke and upper clamp plate, requiring any additional overhead or ceiling clearance space.
