PROBLEM TO BE SOLVED: To set up the capacity of a molding material supply part hopper to be enough as required and to improve the efficiency of work by separating a molding material injection part and a molding material supply part and connecting them by a flexible pipe. SOLUTION: An injection part 1 is composed of a cylinder 11 for driving a measuring/injection part, a cylinder 12 for driving a measuring/injection screw, a measuring/injection screw 13, a measuring/injection part cylinder 14, and a nozzle 15 and has a mold 2 and a mold clamping part 3. A molding material supply part 4 is composed of a hopper 41 and a molding material pressurizing cylinder 42. The injection part 1, the mold 2, the mold clamping part 3, and the molding material supply part 4 are made independent structures, and the injection part 1 and the molding material supply part 4 are connected by a flexible pipe 6. In the flexible pipe 6, a polymer pipe containing at least one of urethane rubber, nitrile rubber, or ethylene-propylene rubber, or an olefin resin, etc., is fitted to the inner wall.
