PURPOSE:To reduce a man-hour and cost by performing molding by casting a molding material into a cavity under a state where a net is floated over a mold surface in the inside of the cavity. CONSTITUTION:When a molding material is cast within a cavity 1a of a mold 1 by performing clamping, molding can be performed under a state where a net 12 is separated from mold surfaces 3a, 4a for the cavity, and a pad 11, where the predetermined net 12 is buried, can be molded in one molding. Then at the time of breaking of the mold after molding, along with a downward movement of a movable mold 3, a core 4 is ejected downward through an ejection pin 5, and when mold release from the core 4 is performed, the predetermined pad 11 can be obtained. Therefore, the pad 11 where the net 12 is buried can be manufactured in one molding by casting a molding material within the cavity 1 under a state where the net 12 is floated over the mold surfaces 3a, 4a for the cavity within the cavity 1a. |
