Abstract
This invention relates to hot tip bushing means for a synthetic resin injection molding machine, which can reduce the pressure loss at the injection molding time and determine the position of a heating tip easily and accurately. To attain this purpose, a straight resin flow passage is formed axially in a cylindrical body of the hot tip bushing means and the fused resin passing through the straight resin flow passage is heated by an outer heater. Further, a cylindrical body of the hot tip bushing means which is near the heating tip is fit to a mold sprue, thereby the position of the heating tip is determined easily and accurately.
