摘要

The device has a screw nut screwable into a recess (4) and supporting a heat conductive tip, which is arranged at a tool-side end of a runner (3) in the recess. The nut has an outer thread corresponding with an inner thread (6) of the recess, and is provided with two axially directed holes, which accommodate tools. A section (5) formed in the recess causes extension of diameter of the runner, and extends up to a free end of a gating rail (2). The inner thread does not extend up to a free end of the runner.
