The machine includes a lifter table for lifting a pattern plate and flask which hold molding sand and a pre-compacting member and a pressing member disposed above the lifter table for horizontal movement and for being inserted into the flask when the lifter table lifts the flask. The pre-compacting member includes a thin-plate body to be positioned slightly spaced apart from an inner surface of the flask or inner and outer surfaces of a pattern when inserted into the molding sand held in the flask. The pressing member includes a squeezing body that presses the molding sand from above.
