ABSTRACT:
A mold tool clamping device (30) for a blow mold comprising two mold halves (13and13). For fixing of the rear blow mold half to the clamp plate associated therewith, there is provided at least two wedge locks or cam locks, which are provided in a symmetric arrangement relative to the “vertical” transverse central plane of the rear mold tool, which are clampable with wedges, which, supported on the back side of the clamp plate, transverse to the longitudinal axis of the clamp bolts, are drivable into their anchor groove of anchor keyways, wherein these wedge locks are so arranged, that the wedges are drivable “from the side” into their clamp position in designed “grooves” of the clamp bolts complimentary thereto. This makes possible a rapid and positionally accurate securing of the rear mold half to its rear clamp plate.
