The present invention relates to an injection moulding device (10) for producing a component, having an injecting unit (12) for supplying a flowable raw material and having an injection mould (14) for shaping the raw material, wherein the injecting unit (12) has at least one injection channel (16) for injecting the raw material into the injection mould (14), wherein the injection channel (16) is heatable by a temperature control element (18) for controlling the temperature of the raw material located in the injection channel (16), and wherein the injecting unit (12) can be brought into contact with the injection mould (14) for transfer of the raw material out of the injection channel (16) into the injection mould (14), wherein at least one closure element (22) is provided for closing the injection channel (16) at an injection opening (20) for transferring the raw material from the injection channel (16) into the injection mould (14), wherein, during closing of the injection channel (16), the closure element (22) can be arranged such that it bounds a component contour (24) of the injection mould (14). An injection moulding device of this type permits an injection moulding process without a sprue.
