To improve productivity.SOLUTION: A core molding device includes: a storage part 20 storing core sand; a cylindrical kneading pot 11 into which the core sand is charged through a charging port to which the storage part 20 is connected; a kneading stick extending in a longitudinal direction of the kneading pot 11 inside the kneading pot 11 and also rotating around a shaft parallel to the longitudinal direction to knead the core sand; and a piston 14 jetting the kneaded core sand through longitudinal one end of the kneading pot 11. The kneading pot 11 turns around a first shaft and is shifted to a horizontally laid state and a vertically raised state. The core sand is charged into the kneading pot 11 through the charging port located at the upper side of the kneading pot 11 and is kneaded with the kneading stick in the horizontally laid state. The core sand is jetted downward by the piston 14 and is charged into a mold in the vertically raised state. The storage part 20 is connected to the kneading pot 11 so as to be turnable around a second shaft parallel to the first shaft, and retains its posture while connected to the kneading pot 11 when the kneading pot 11 is turned.SELECTED DRAWING: Figure 1 【課題】生産性の向上。【解決手段】中子砂を貯蔵する貯蔵部２０と、貯蔵部２０が連結された投入口から中子砂が投入される筒状の混練釜１１と、混練釜１１の内部において混練釜１１の長手方向に延設されると共に、長手方向に平行な軸周りに回転し、中子砂を混練する混練棒と、混練された中子砂を混練釜１１の長手方向の一端から射出するピストン１４と、を備え、混練釜１１は、第１軸周りに回動して横倒しの状態と縦起こしの状態とに移行でき、横倒しの状態において、混練釜１１の上側に位置する投入口から中子砂を混練釜１１に投入し、混練棒によって混練し、縦起こしの状態において、ピストン１４によって下方向に中子砂を射出して型に充填する、中子造型装置。貯蔵部２０は、第１軸と平行な第２軸周りに回動可能に混練釜１１に連結されており、混練釜１１が回動する際、混練釜１１に連結したまま、姿勢を維持する。【選択図】図１
