Title:
CASTING DIE DEVICE AND CASTING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/083543
Kind Code:
A1
Abstract:
The present invention relates to a casting die device (50) and a casting method used to obtain a cast product (10) in which an inner bore (14), at least one end of which is open, is formed. The casting die device (50) has a core pin (46) for forming the inner bore (14) in the cast product (10), and a vibration-transmitting member (90) for transmitting vibrations from a vibrator (98) of a micro-vibration machine (100) to the core pin (46). When casting is being performed, vibrations from the vibrator (98) are imparted to the core pin (46) by way of the vibration-transmitting member (90). The vibrations also propagate to sites surrounding the core pin (46), in molten metal (66) that has been poured into a cavity (60).
