Patent number: 11084088Abstract: A core manufacturing apparatus includes: a storage unit that stores core sand; a kneading vessel configured to be fed with the core sand; a kneading rod configured to knead the core sand; and a piston configured to eject the kneaded core sand. The kneading vessel 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 is configured to eject the core sand downward and pack it into a mold with the kneading vessel in the vertically standing state. The storage unit includes a valve that opens and closes the feed port. The storage unit is coupled to the kneading vessel so as to be turnable around a second shaft and configured to maintain the same posture with the valve in contact with the feed port while the kneading vessel turns.Type: GrantFiled: September 21, 2020Date of Patent: August 10, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Naoya Kajita, Junji Asano, Masahiro Umeda, Shota Nagashima, Masaomi Mitsutake
