Similarly, a mold 14 is disposed corresponding to the first nozzle 11, and the mold 14 has a fixed mold 141 and a movable mold 142. The movable mold 142 is coupled to a second moving mechanism 15, and the fixed mold 141 and the movable mold 142. A cavity 143 is formed in the middle portion, and a second nozzle 16 is movably fixed in the fixed mold 141. The second nozzle 16 has a metal flow path 161, and the metal flow path 161 can be extended or additionally provided on the second nozzle 16. There is a water channel 162 which is conventionally known. The metal channel 161 is connected to the cavity 143, and the first nozzle 11 is located outside the mold 14.
