PURPOSE:To strongly and closely seal a film like interior object in a molded product at a specified position. CONSTITUTION:A pinch-off groove 6b and a material sump groove 6c are formed to the outer periphery of the cavity 6a of a first mold 6 and the fine groove 6d allowing the cavity 6a to communicate with the pinch-off groove 6b and the material sump groove 6c is formed. When internal pressure is applied to the curable molding material received in the cavity 6a, said pressure escapes to the pinch-off groove 6b or the material sump groove 6c through the fine groove 6d. |
