Zusammenfassung:	An injection head is described, in particular for injection moulding thermoplastic material, having a multiplicity of uniformly distributed sprue nozzles (3) which are connected to a feed channel (8) for the material to be extruded, and devices for monitored temperature control of said sprue nozzles (3). Each of the sprue nozzles (3) has an outer jacket (4) in the interior of which a core (5) is provided which has helical ribs (6). These ribs define a helical interspace (7) through which a temperature-control fluid is circulated, the feed channel (8) provided in the interior of the aforementioned core being connected to a sprue bush (9) which can be inserted into the mould (2).
