<P>PROBLEM TO BE SOLVED: To upgrade the quality of an injection-molded piece by molding it to a high precision in plate thickness. <P>SOLUTION: This injection-molding machine 11 is constituted of a cavity side half 12, of a mold, with a recessed part 22 formed on the periphery of a molding surface 14 and a movable half 13 of a mold, equipped with an surplus material removing part 23, which can jut out toward the cavity side half 12 side and is mounted on the periphery of the molding surface 15. In addition, a cavity 16 is formed between the cavity side half 12 and the movable half 13 and has a surplus part B formed on the outer peripheral side of a finished product forming part A between the molding surface 14 of the cavity side half 12 and the molding surface 15 of the movable half 13. Inside the cavity 16, a molded piece material 31 for forming a separator is packed, and the surplus material removing part 23 is allowed to protrude to the cavity side half 12 side and the molding piece material 31 crowded out into the surplus part B is removed after the molding piece material 31 is full to the capacity in the entire finished product forming part A, with the surplus crowded out into the surplus part B. <P>COPYRIGHT: (C)2007,JPO&INPIT |
