An injection moulding machine wherein the state of nozzle contact can be easily observed from the outside of a mold clamping unit (10). Monitoring holes (16a, 16b) are provided in a fixed platen (1) of the mold clamping unit (10). The monitoring holes (16a, 16b) are caused to penetrate from at least either of the front and back sides of the mold clamping unit (10) toward a locating hole (12) for locating a sprue bush (31) of a mold. It is possible to provide shutters (22a, 22b) on the monitoring holes (16a, 16b) that are adapted to interlock with a purge shield (20) for opening and/or closing. Furthermore, it is possible to construct the injection moldig machine such that the monitoring holes (16a, 16b) can be used for unobstructed observation via windows (34a, 34b) provided in a purge shield (30). |
