A sizing device adapted for automatic blow mandril adjustment for plastic blow molding machines is provided with at least blow mandril having a blow nozzle and a cutting edge and forming a module with a blow mandrel carrier. The blow mandril is guided in a guide plane extending perpendicularly to the axis of the blow mandril for adjustment in relation to a module carrier suitable for connection with the blow molding machine in the axial and any desired radial direction and in both directions is respectively able to be locked by means of a respective setting means on the blow mandril carrier adapted to be connected with the module carrier. The blow mandril is urged in relation to the module carrier axially toward the blow nozzle into the home position and is able to be moved in the opposite direction overriding the biasing action as far as engagement with the blow mandrel carrier. The setting means for locking the at least one blow mandril in position are able to be operated by means of pressure medium.
