<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a multicolor molded article capable of molding the multicolor molded article in which a boundary portion is formed between a first molded article and a second molded article over both a first plate part and a second plate part disposed in a mutually bent shape. <P>SOLUTION: A trim board 20 has a groove part 23 formed extended along the boundary between the first molded article 30 and the second molded article 40 in a shape extending over a main surface part 21 and an erected wall part 22. The method includes a first molding step for molding the first molded article 30 by injecting molten resin into a first molding space 91, and a second molding step for molding the second molded article 40 by injecting molten resin of a color different from the first molded article 30 in a second molding space 92. In the first molding step, a slide die 70 having an extending face 71A extending along the extending direction of the groove part 23 is moved in the extending direction of a bent face configured by the main surface part 21 and the erected wall part 22, to bring an opening on the side of the second molding space 92 in the first molding space 91 to a closed state by the extending face 71A. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
