ABSTRACT:
Known apparatuses to inject liquids, in particular plastics into injection moulds have closure rods which remain in the gating when the closure system is opened. In the present apparatus the liquid passage always is completely free when the closure system is opened, because the closure rod can be totally retracted from the liquid passage. This can be accomplished in two ways: either the liquid passage extends in a bended manner or the closure rod has a side view in the configuration of a sector or a circle.
