PROBLEM TO BE SOLVED: To provide a vibration device capable of sufficiently transmitting vibrations to a core pin forming an inner hole, and thereby sufficiently transmitting the vibrations to molten metal in a cavity. ! SOLUTION: A casting mold device 50 for obtaining a casting has a core pin 46 for forming an inner hole in the casting. A vibration device 51 is provided, which adds vibrations to the core pin 46. The vibration device 51 has a microvibration machine 100 equipped with a vibrator 98, and a vibration transmission member 90 coming close to the core pin 46. For example, the vibrator 98 repeatedly abuts on/separates from the vibration transmission member 90, thereby adding the vibrations to the core pin 46. The vibrations added to the core pin 46 is further transmitted to a part surrounding the core pin 46 in molten metal 66 injected into a cavity 60. ! COPYRIGHT: (C)2015,JPO&INPIT |
