INSERT FOR AN INJECTION-MOULDING NOZZLE AND INJECTION-MOULDING NOZZLE HAVING SUCH AN INSERT

The invention relates to an insert (20) for an injection-moulding nozzle (10) of an injection-moulding device, wherein the injection-moulding nozzle (10) has a nozzle body (12) which extends in a longitudinal direction (L) and in which at least one melt duct (16) for a flowable compound to be processed is formed along the longitudinal direction (L) between a first end (13) and a second end (14), wherein the at least one melt duct (16) opens into a mould impression (18), formed in the injection mould, of the injection-moulding device. The insert (20) has a main body (30) which extends along the longitudinal direction (L). The main body (30) of the insert (20) has a portion (40) which, in the mounted position of the insert (20) in the injection-moulding device, is arranged in the region of the second end (14) of the nozzle body (12), and a second portion (50) which, in the mounted position of the insert (20) in the injection-moulding device, is supported on a tool plate (17) of the injection-moulding device. In order, in addition to good wear protection for the injection-moulding nozzle, to allow optimized temperature control of the flowable compound conveyed in the injection-moulding nozzle, the invention provides that the second portion (50) of the main body (30) has a contact face (52) for contact with the tool plate (17) of the injection-moulding device, wherein at least one recess or depression (54) is formed in the contact face (52).
