Abstract
Tool insert for the gate of a hot-channel nozzle for an injection molding machine, which tool insert connects to the front (tool-side) part of the hot-channel nozzle and in turn is capable of insertion into a corresponding recess of the tool. The tool insert consists of a front cylindrical fitting piece with flow channel and an accommodating head for the nozzle. The accommodating head is provided at its (per se cylindrical) outer surface with one or more projections capable of cutting, which in the radial direction have an extension that is greater than the radius of the accommodating bore provided in the tool for accommodation of the accommodating head of the tool insert. The projections capable of cutting are designed in such a way that, upon insertion of the tool insert into the said accommodating bore of the tool, a guide grooves are cut into the inner surface of the accommodating bore in the tool.
