A method for molding a core of a vacuum insulation panel, the method comprising: supplying core material to a molding apparatus comprising: an upper molding plate and lower molding plate facing each other; and a molding cast closing a molding space where the core is molded from outside; characterized in that the method comprises the following steps: press-molding the core material by moving the upper and lower molding plates (131, 111) along their approaching direction to press the core material, wherein the press-molding comprises: moving the lower molding plate to approach an upper side of the molding cast with an upper side of the molding space opened; closing the upper side of the molding space by moving the upper molding plate downwards when the lower molding plate reaches a predetermined location, near to the upper side of the molding space; and pressing the core material by moving the lower molding plate towards an upper side of the predetermined location; moving the press-molded core outside the molding cast while maintaining the same distance between the pair of molding plates (131, 111); and discharging the molded core, wherin a cross-sectional area of the surface of the upper molding plate facing the molding cast is bigger than a cross-sectional area of the molding cast; and when a force is applied to the upper molding plate, the upper molding plate moves downwards, and the upper molding plate moves until a lower surface of the upper molding plate contacts the molding cast and closes an upper side of the molding cast. supplying core material to a molding apparatus comprising: an upper molding plate and lower molding plate facing each other;
