| 摘要 | To provide a method and a machine for forming flaskless molds with a shortened cycle time even if many cores are placed, to thereby achieve efficient molding. The flaskless molding machine comprises four pairs of upper and lower flasks 4, each pair comprising an upper flask 2 and a lower flask 3, a device 5 for pivoting the flasks to move the four pairs of upper and lower flasks via four stations, including a molding station, a first station for placing a core, a second station for placing a core, and a station for extracting the molds, a match plate 6, a pair of squeeze plates 7, 8, a storage tank 9 for sand, a device 10 for moving forward and backward around an axis that moves around the axis the upper and lower flasks where an upper mold cavity and a lower mold cavity are formed so that ports for introducing molding sand can receive the molding sand from a pair of nozzles for introducing molding sand, a squeezing device 11, a device 14 for moving the upper and lower flasks, and a device 15 for extracting the molds. | ||||||
