An injection moulding tool for producing at least one injection-moulded part with an outer shape and an inner shape includes at least one cavity and, for every cavity, one hot-runner nozzle connected thereto, which has an annular nozzle mouth for injecting at least one melt into the cavity. The at least one cavity is formed by a cooled die, which forms the outer form for the outer shape of the injection-moulded part to be produced, and by a core, which forms the inner form for the inner shape of the injection-moulded part to be produced. The hot-runner nozzle has a nozzle core and a hollow needle, which can be moved along the nozzle core for opening and closing the annular nozzle mouth. The nozzle core protrudes beyond the annular nozzle mouth of the hot-runner nozzle and the nozzle core forms the core of the cavity of the injection mould.
An injection moulding tool for producing an injection-moulded part with an outer shape and an inner shape comprising a cavity and a hot-runner nozzle connected to the cavity having an annular nozzle mouth for injecting at least one melt into the cavity;
A hot-runner nozzle for an injection moulding tool, wherein the hot-runner nozzle has an annular nozzle mouth, a nozzle core and a hollow needle displaceable along the nozzle core for opening and closing the annular nozzle mouth, wherein the nozzle core protrudes beyond the annular nozzle mouth of the hot-runner nozzle and wherein the nozzle core in the installed state of the hot-runner nozzle forms a core of a cavity of the injection moulding tool.
