Abstract
The present invention relates to a casting die device and a casting method used to obtain a cast product in which an inner bore, at least one end of which is open, is formed. The casting die device has a core pin for forming the inner bore in the cast product, and a vibration-transmitting member for transmitting vibrations from a vibrator of a micro-vibration machine to the core pin. When casting is being performed, vibrations from the vibrator are imparted to the core pin by way of the vibration-transmitting member. The vibrations also propagate to sites surrounding the core pin, in molten metal that has been poured into a cavity.
