Claim Text:
1. A method of molding a composite molded article providing a first mold member attached to a fixed platen, a second mold member attached to a movable platen and a movable mold member which can rotate and move in a mold opening/closing direction between the first mold member and the second mold member, using the first mold member and the movable mold member to mold a primary molded article by primary molding, switching the movable mold member which holds the primary molded article with the movable mold member positioned with the second mold member, then using the second mold member in which the primary molded article is inserted and the movable mold member to mold a secondary molded article by secondary molding, said method of molding a composite molded article characterized in that the movable mold member approaches to the first mold member to form a first cavity, the movable platen, to which the second mold member is attached, approaches to the movable mold member to form a second cavity upon which the mold closing is completed; the primary molding and the secondary molding can be switched so that the second mold member molds a primary molded article and the first mold member molds a secondary molded article; the primary molding and the secondary molding are executed by non-continuous different steps at points of time different from each other, and either of the primary molding and the secondary molding is performed by compression molding reducing a volume of the first or second cavity, with the mold member for the compression molding opening to increase a volume of the cavity for the compression molding before the compression molding step; and the primary molding is performed after the secondary molding in which the primary molded article is inserted to mold a secondary molded article, wherein the movable mold member and the second mold member are integrally moved together toward the first mold member to perform the compression molding.
