ABSTRACT INJECTION NOZZLE FOR USE ON A PLASTICIZING CYLINDER OF AN INJECTION UNIT OF AN INJECTION MOLDING MACHINE The outlet portion of the nozzle passage of the injection nozzle is defined by the inside peripheral sur- face of a mouthpiece, which is adapted to be axially for- ced against the nozzle body by means of a clamping ring, which engages the mouthpiece and surrounds the nozzle body around a forward portion thereof, which is smaller in dia- meter than the rear portion of the nozzle body. The contact pressure between the mouthpiece and the nozzle body is adapted to be controlled by screw means, which are screw- threadedly connected to screw threads of the nozzle body. The mouthpiece is made of a material which has a higher abrasion resistance than the material of the nozzle body.
