Mold system for composite molding

A mold system for composite molding comprising:

• a first mold member attached to a fixed platen for a primary molding, a second mold member attached to a movable platen for a secondary molding, 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,
• said mold system characterized in that:
• the movable mold member is positioned to enable switching between the first mold member and the second mold member;
• the movable mold member is provided freely engagable/disengagable with the first mold member and the second mold member by clampers;
• 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;
• either of the primary molding and the secondary molding can be performed by either of the first mold member or the second mold member;
• 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.
