Individual pneumatic pulses for discharging gangs of rubber mouldings - to overcome the effects of time differences as mouldings part from their cores

摘要

Appts. for simultaneously disengaging several individual rubber mouldings from their respective mould cores using compressed air assistance, involves an air ballast reservoir associated with each ejector system. The reservoirs are filled simultaneously but then isolated to discharge independently to their specific moulds. Used esp. for releasing undercut forms such as bellows so that the air supply for releasing one moulding is not starved by premature loss via an adjacent mould which vents following an earlier disengagement of its moulding.
