The return water pipe includes the first upper mold return water pipe 7, the second upper mold return water pipe 8, and the upper and lower return water movable pipes 6. The first upper mold return water pipe 7, the second upper mold return water pipe 8, and the upper and lower return water movable pipes 6 are nested so that the return water pipe can move up and down with the upper mold plate.
