Abstract

A core-molding device (50) provided with a controller (100) configured so as to control actuation so that all intervals overlap, the intervals being an interval in which cast sand (41) is blown into a cavity (36) by the solenoid valve (11), an interval in which vibrations are applied by a vibrator (20) to the casting sand (41) thus blown into the cavity (36), and an interval in which the casting sand (41) thus blown into the cavity (36) is suctioned by a vacuum pump (24) so as to be drawn to the upper surface side of the cavity (36).
