Abstract

PURPOSE:To obtain molds for a multi-colored molding, which can be operated by one-time clamping operation and incapable of forming flaws, etc., on a molding, by a method in which a fixed side sliding core and a movable side sliding core which can move slidably in the axial direction through each part of a fixed core and a movable core are provided. CONSTITUTION:A fixed side sliding core 25 and a movable side sliding core 21 are positioned at their rising limits, and parts of left- and right-handed cavities formed by a fixed core 12 and a movable core 16 is closed by the movable side sliding core 21. After a resin injected for the primary molding is cooled, the sliding cores 21 and 25 are moved to their lowering limits, a cavity formed by both the sliding cores 25 and 21 is matched with the primary molding, and another resin is injected for the secondary molding.
