(1) Since the nozzle vibrates to break the core, the insertion load is light, smooth work is possible, and the nozzle is less worn. When inserting the air blow nozzle into a thin and deep core, for example, the core of a water jacket for cooling the piston, in the case of aluminum, the core has a hard melting point and the nozzle is difficult to enter deeply because the melting temperature is low. Although it wears quickly, the present invention vibrates the air blow nozzle with a vibrator to sand out while breaking the core, so the insertion load is light and the wear of the nozzle is reduced.
