Abstract
PURPOSE: To form a main mod accurately by superposing a molding flask on the upper surface of a pattern plate provided with a pressure reducing chamber and vent holes, filling the space with molding sand containing binder, covering the upper surface of the molding flask with a film and squeezing the molding sand by sucking making the inside of the molding flask negetaive pressure.
CONSTITUTION: A molding flask 7 is superposed on the upper surface of a pattern plate 1 provided with a pressure reducing chamber 2 and plural vent holes 4 connected to it and the space formed by the molding flask 7 and pattern plate 1 is filled with molding sand 9 containing binder. Next, the upper surface of the molding flask 7 is covered airtightly with a flexible film sheet 10. Here, a suction device connected to the pressure reducing chamber 2 is actuated to make the inside of the molding flask 7 negative pressure through a duct 11 and vent holes 4, and the molding sand 9 is squeezed by suction through the film sheet 10.
