摘要： Provided is a core manufacturing apparatus including: a storage unit configured to store 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 and pack the core sand into a mold with the kneading vessel in the vertically standing state. The storage unit is turnably coupled to the kneading vessel and configured to remain coupled to the kneading vessel in the same posture while the kneading vessel turns.

摘要： 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.

摘要： Agitating pins employed in a kneading apparatus extend in the horizontal direction and rotate around a rotation axis of an agitator extending in the horizontal direction, so that the kneading apparatus can repeat a process in which a material is kneaded and beaten against an inner wall surface of a kneading vessel and the material adhering to the inner wall surface of the kneading vessel, especially on the upper side from the rotation axis of the agitator, falls under its own weight through the clearance between the agitating pins. As a result, the material hardly adheres to the inner wall surface of the kneading vessel, so that the kneading efficiency can be enhanced.
