摘要： The invention relates to an injection tool for producing components by injection moulding, having a plurality of cavities (5) for forming a product in each case, having an injection nozzle (6) for injecting plastics materials for each cavity (5), wherein an injection nozzle (6) has an injection channel which can be closed by a nozzle needle (14), in order to control the injection operation, and wherein an actuating device is provided, this being designed to move the nozzle needle (14) axially between a first end position and a second end position, wherein an adjustable stop (18), which defines the first end position, is provided. Specific control of the material flow can be achieved in that the adjustable stop (18) is designed as a screw, which is formed coaxially in relation to the nozzle needle (14) and can be adjusted by an electric motor (13). The invention further relates to a method for operating such an injection tool.
