To provide a mold which enables a passage of a molding liquid to be formed compactly in a hydroforming system, and to provide a manufacturing method of a pipe molding product which uses the mold.SOLUTION: A mold 3 is used in a hydroforming system which fills a pipe P with a molding liquid to plastically deform the pipe P with a liquid pressure of the molding liquid. The mold 3 includes: valves 9 each of which is disposed in the mold 3 and may open or close a passage 200 for discharging the molding liquid from the pipe P; and transmission mechanisms 8 each of which converts movement for mold closing into movement for closing the passage 200 with the valve 9.SELECTED DRAWING: Figure 1 【課題】ハイドロフォーミングシステムにおいて成形液の流路をコンパクトに構成できる金型及び該金型を用いた管材成形品の製造方法を提供する。【解決手段】金型３は、管材Ｐに成形液を充填して該成形液の液圧により管材Ｐを塑性変形させるハイドロフォーミングシステムに用いられる。金型３は、該金型３内に配置され、管材Ｐから成形液を排出する流路２００を開閉可能なバルブ９と、型締めの動きをバルブ９が流路２００を閉弁する動きに変換する伝達機構８と、を備えている。【選択図】図１
