in a injection molding unit for use in an injection molding machine for processing synthetic material a driving unit is provided for axially displacing the injection molding unit in a direction of an injection axis . an injection unit , symmetrically arranged with respect to the injection axis , is provided for axially driving a rotatable feed screw placed inside a plasticizing cylinder . the injection unit is connected with an injection bridge . since the driving unit is also arranged symmetrically with respect to the injection axis and is integrated in the injection molding unit , it is possible to realize a moment free nozzle contact point and a compact injection molding unit in a simple constructional way .
