The invention relates to an injection molding machine having a three platen design with: a first die platen (1); a second die platen (2) that can move along the machine axis (10); an end platen; a closing unit (7) acting upon the second die platen, and; at least two injection units (S, 15). A first of these injection units is designed for injecting through a nozzle opening (11) passing through the first die platen (1) into a partial tool (12) fastened thereto, whereas the at least one second injection unit (15) is assigned to the second die platen (2), is mounted together with this displaceable supporting structure (14) and is designed for injecting into a partial tool (23) fastened to the second die platen (2). The second die platen (2) does not have a nozzle opening, the axis (19) of the at least one second injection unit (19) forms an acute angle (α) with the machine axis (10), and the nozzle (22) of the second injection unit (15), when in its injecting position, is in contact with the tool while being located at a distance from the machine axis (10). The supporting structure (14) for the second injection unit (15) is supported on the end plate (4).
