Blow molding machine

摘要

Each of the clamping plates of the closing unit of the blow molding machine has secured thereto a pivotable locking means which in the calibration position in the swung-up state comes into engagement with a plate which is part of the calibration device. A short friction-type connection which is symmetrical relative to the mold parting plane is thereby established between the blow mold and the calibration cylinder during calibration so that the calibration forces are transmitted in an exact manner. The locking means swing downwards when the blow mold is opened and/or the closing unit returns to the head station. Collisions with other machine parts are thereby ruled out.
