摘要

<P>PROBLEM TO BE SOLVED: To provide an in-mold molded product coating mold and an in-mold molded product coating molding forming method which allow improving the sealing performance for prevention of leakage of the coating agent out of the mold. Ž<P>SOLUTION: The mold includes: a sealing portion molding cavity 45 which has the first molding surface 32 extending from the parting surface 46 of a mold cavity 40 in the direction of matching of a fixed mold 20 and a movable mold 30 and formed in one of the fixed and the movable mold, the second molding surface 28 extending from the parting surface in the mold opening/closing direction for the mold cavity 40 and formed in the other of the fixed and the movable mold and the third molding surface 22C connecting the first molding surface with the second molding surface, is separated outside from the molding cavity and is filled with a resin identical with or different from the resin J packed in the mold cavity to form a sealing portion sealing the first and second molding surfaces; and pressing portions 23 and 24 pressing the pressing surface of the sealing portion formed with the third molding surface under a predetermined pressure so as to pressure-weld the sealing portion with the first and second molding surfaces.
