Hot runners for an injection molding machine

An injection molding machine, comprising:

• a base frame;
• an extruder which includes a first nozzle;
• a runner body having a hot runner formed in an interior thereof, said runner body being disposed between the mold and the extruder and which further includes a second nozzle at an outlet end thereof, the hot runner being substantially L-shaped;
• connecting means engaging said first nozzle wherein said hot runner further comprises a horizontal channel adapted to communicate with the extruder at an inlet end portion of the runner body via said connecting means and a vertical channel communicating with the horizontal channel substantially perpendicular thereto and having said second nozzle at an outlet end of the runner body;
• a support assembly being mounted on said base frame and disposed toward the connecting means between the runner body and the extruder, the inlet end of the runner body being supported by the support assembly and pivotally and slidably longitudinally mounted thereon;
• stopper means fixed to said base frame and provided at the outlet end of the runner body for withstanding the pressing force of the extruder and for positioning the first nozzle wherein the stopper means is movably mounted on said base frame;
• means mounted on said base frame for adjusting the horizontal position of said stopper means and said first nozzle;
• and
• nozzle pressing means for pressing said second nozzle against the mold.
