A cleaning unit of an injection-molding device is provided to maintain a blocking needle of the injection-molding device clean in operation by continuously removing residues of materials from a guide bush and a sealing sleeve of the blocking needle. An injection-molding device(1) comprises a cleaning unit(10) used in the injection-molding device having at least one needle blocking nozzle through which a movable material is fed to a separable forming member; a blocking needle(20) fed to an opening position and a blocking position by a driving unit; and at least one cleaning element(40) arranged at each blocking needle to remove materials deposited on an outer periphery(24) of the blocking needle. The cleaning element is matched on the outer periphery of the blocking needle according to the shape.
