Abstract

A flaskless molding machine includes: an upper flask; a lower flask; an upper sand tank; an upper plate attached to a lower end of the upper sand tank; a first lower sand tank; a second lower sand tank; a lower plate attached to an upper end of the second lower sand tank; a drive unit performing squeezing using the upper plate and the lower plate; an adjustment drive unit moving the first lower sand tank; a first detector detecting a height position of the first lower sand tank; a second detector detecting a height position of the second lower sand tank; and a control unit operating the drive unit and the adjustment drive unit so that the height positions of the first communication port and the second communication port coincide with each other, based on detection results of the first detector and the second detector.
