PURPOSE:To obtain a molded product generating no unimpregnated part or foam part by preventing the slip-off of a reinforcing fiber being a problem at the time of the molding of a large container-shaped reinforced plastic molded product such as a bathtub and improving molding workability so as not to generate the injection difficulty of a synthetic resin at the time of the formation of a gel coat layer. CONSTITUTION:An upper mold 32 is made of a recessed fiber reinforced plastic member and, as a lower mold 31, a projected mold directing the opening part of a molded product downwardly is used and a plurality of space parts 45, 46 formed by elastomers 37, 38, 39 are provided to the entire peripheral edge part of the mold 31 and a plurality of suction ports 33, 34 are provided to the spaces while a suction port 35 for reducing the pressure of a mold gap is provided to the upper part of the recessed upper mold 32 and a synthetic resin injection port 36 is provided to the peripheral edge part of the recessed upper mold 32. |
