Injection nozzle for an injection molding machine

An injection nozzle for use in an injection molding machine, said injection nozzle comprising:

• a nozzle body having a first end and an opposite second end, wherein said nozzle body is symmetrically disposed around a center axis that extends through said first end and said second end, and wherein said nozzle body has a tip section, a nut section, and a threaded section that is interposed between said first end and said second end;
• an output orifice disposed at said first end of said body, wherein said output orifice is concentric with said center axis;
• an intake orifice disposed at said second end of said body, wherein said intake orifice is concentric with said center axis;
• a conduit that extends through said nozzle body between said intake orifice and said output orifice, said conduit having a first zone that extends into said nozzle body from said output orifice and a second zone that extends from said first zone to said second end, wherein said first zone and said second zone meet at a transition area within said conduit;
• wherein said tip section of said nozzle body has an exterior that tapers from said first end to a minimum in an area that surrounds said transition area of said conduit;
• and
• a plurality of fins that radially extend into said first zone of said conduit toward said center axis from said nozzle body, wherein said plurality of fins are configured to conduct heat from said first zone of said conduit into said nozzle body, wherein each of said plurality of fins has a ridge surface that faces said center axis.
