PROBLEM TO BE SOLVED: To provide an injection molding method, applying a substantially uniform force on a mold and the like upon mold clamping or injection molding and capable of molding even in a narrow space. SOLUTION: When primary forms are molded by injecting a molten resin into cavities 44, 45, 44', 45', formed of a fixed mold 20 and two pieces of slide molds 40, 40', divided substantially equally, even number of pieces of forms are molded at positions, whose center of symmetry is positioned at the substantially central axis of the fixed mold 20. When the primary forms are solidified, the slide molds 40, 40' are slid to abut the primary forms against each other and when the molten resin in injected into the abutted part to integrate and mold the primary forms, the molding is effected at positions, whose center of symmetry is substantially the central axis of the fixed mold 20. |
