More Information
Summary:A core manufacturing apparatus includes: a storage unit (20) that stores core sand; a kneading vessel (11) configured to be fed with the core sand; a kneading rod (12) configured to knead the core sand; and a piston (14) configured to eject the kneaded core sand. The kneading vessel (11) is capable of transitioning between a horizontally lying state and a vertically standing state and configured to be fed with the core sand in the horizontally lying state. The piston (14) is configured to eject the core sand downward and pack it into a mold with the kneading vessel (11) in the vertically standing state. The storage unit (20) includes a valve (V3) that opens and closes the feed port (11a). The storage unit (20) is coupled to the kneading vessel (11) so as to be turnable around a second shaft (A2) and configured to maintain the same posture with the valve (V3) in contact with the feed port (11a) while the kneading vessel (11) turns.
