PURPOSE:To form a molded form integrated with a skin by forming the skin material into a bag shape and injecting resin from the supply port thereof and compression-molding it. CONSTITUTION:The hole 23 of skin material 20 is allowed to coincide with the nozzle of a bottom force 6 in a state wherein a top force 5 has been raised. The skin material is spread on the bottom force 6 and stuck by a sticking material 21. Then the top force 5 is lowered and stopped or decelerated in the position of about 10mm to 50mm a part from the final closed position of the mold. Together therewith molten resin 22 is supplied into the skin material 20 from an injector 10. When only the prescribed amount of resin 22 is supplied, the top force 5 is relowered at the intact velocity or the accelerated velocity. While compression-molding the resin, the top force 5 spreads the resin 22 to the inside of the skin material 20. At this time, the wrinkle of the skin material 20 is stretched and a good state is obtained. When the prescribed amount of molten resin 22 is supplied, the gate part opening and closing mechanism 13 of the injector 10 is closed and back flow of resin 22 is prevented. The top forst 5 is furthermore lowered and reaches the final mold clamping position and a molded form is produced. |
