<P>PROBLEM TO BE SOLVED: To provide a forming mold capable of suppressing the appearance defect of a molded product since the sticking object is hardly deposited in a slit and capable of improving productivity. <P>SOLUTION: The forming mold for molding a cylindrical molten resin body continuously extruded through the mold is provided with a cylindrical part 11 extended along the extruding direction of the molten resin body and into which the molten resin body is inserted. A slit 13 is formed in the cylindrical part 11 and the edge surface of the slit 13 is inclined with respect to the inner peripheral surface of the cylindrical part 11 so that the slit 13 has a width gradually extended from the outside of the cylindrical part 11 toward the inside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
