Injector head for injection molding machine

摘要

A distributing head is attached to the lower end of the barrel of a reciprocating screw injector and carries three injection nozzles which inject molding material into three mold cavities during each injection cycle. The nozzles are supported within sleeves which are surrounded by tubular jackets adapted to receive a heat exchange liquid, the liquid being circulated successively through successive ones of the jackets.
