PROBLEM TO BE SOLVED: To promote the filling effect by efficiently transferring the vibration to the casting sand (green sand or self-curing sand) in a main molding flask or a core box without consuming a large energy (without any large vibration motor) to give the sufficient fluidity to the casting sand. SOLUTION: In a vibration casting method and its apparatus therefor, the casting sand is fed to the molding flask, and the casting sand is filled by giving the vibration to the casting sand. The casting sand is fluidized by directly applying the vibration to the casting sand from the top of the molding flask, and fill the casting sand while pressing the sand from the top at the same time. The core box used in this method is provided with a sand storage unit on its upper portion, and the sand storage unit has a vibrating direction regulating structure to direct the vibration and the pressure from the top downward.
