Abstract (en)
[origin: EP1952912A1] Disclosed is a molding method for separating a cope flask and a drag flask from a match plate at the same time. The method comprises the steps of: holding the match plate between the cope and drag flasks; inserting an upper squeeze member and a lower squeeze member into openings of the cope and drag flasks, which are opposed to the match plate, to define an upper molding space and a lower molding space, respectively; filling the defined molding space with molding sand; and driving the upper and lower squeeze members toward the match plate to squeeze the molding sand within the upper and lower molding space to mold an upper mold and a lower mold at the same time. The cope and drag flasks that are included within said molded upper and lower molds are forcibly pushed away from the match plate at the same time when the flasks are stationary.
