Abstract
A hot or cold runner device for an injection mold includes a distributor block for polymer melts or polymeric liquids such as liquid silicone. The distributor block includes at least one central supply line, at least one melt channel, at least one fluid outlet, and at least one exchangeable deflection and/or distribution insert. The deflection and/or distribution insert has a sleeve and a cone element for deflecting and/or distributing the melts or liquids and is mounted without gaps and without offset at flow channel transitions by a pressing-in process, and the cone element is held in the sleeve in a self-locking manner.

A hot or cold runner device for an injection mold, comprising:
- a distributor block for polymer melts or polymer liquids, wherein the distributor block has at least one central feed line, at least one melt channel, at least one fluid outlet;
- and
- at least one exchangeable deflection and/or distribution insert,
- wherein the deflection and/or distribution insert has a sleeve and a cone element for deflecting and/or distributing the melts or liquids, and the deflection and/or distribution insert is mounted without gaps and misalignments or without offset at flow channel transitions by a pressing-in process, and
- wherein the cone element has an outer cone, an inner surface of the sleeve is conical, and outer cone of the cone element and the conical inner surface of the sleeve have a cone angle dimensioned in such a way that the outer cone of the cone element and the conical inner surface of the sleeve are held against each other in a self-locking manner.
A method for forming and mounting a deflection and/or distribution insert in a distributor block of a hot or cold runner device for an injection mold, the method comprising:
- providing at least one exchangeable deflection and/or distribution insert, wherein
- the deflection and/or distribution insert has a sleeve and a cone element for deflecting and/or distributing the melts or liquids, and wherein the cone element has an outer cone, an inner surface of the sleeve is conical;
- providing a distributor block for polymer melts or polymer liquids, wherein the distributor block has at least one central feed line, at least one melt channel, at least one fluid outlet;
- and
- mounting the sleeve and the cone element without gap and misalignment or without offset at flow channel transitions by a pressing-in process so that the sleeve and cone element are held in a self-locking manner in the distributor block, wherein each of the outer cone of the cone element and the conical inner surface of the sleeve have a cone angle dimensioned in such a way that the holding in the self-locking manner occurs.
