To provide a mold that can ensure high visibility regarding a state of a molten resin injected into a cavity without causing a problem due to soaring manufacturing cost or mechanical impact.SOLUTION: An injection molding mold comprises: a fixed mold 2 arranged in a fixed state; a movable mold 3 movable with respect to the fixed mold; and a take-out member 20 movable with respect to the movable mold. A window member 21 formed of a transparent resin material is made removable with respect to the movable mold. An observation hole 23 is formed in at least one of the fixed mold and the movable mold so that a cavity 25 can be visually recognized through the window member attached to the movable mold. When the fixed mold and the movable mold are released, the window member is taken out from the movable mold by the take-out member.SELECTED DRAWING: Figure 1 【課題】製造コストの高騰や機械的な衝撃による不具合の発生を来すことなくキャビティに射出される溶融樹脂の状態に関する高い視認性を確保できる金型の提供。【解決手段】固定された状態で配置された固定型２と、固定型に対して移動可能な可動型３と、可動型に対して移動可能にされた取出部材２０とを備え、透明な樹脂材料によって形成された窓部材２１が可動型に対して着脱可能にされ、固定型又は可動型の少なくとも一方には可動型に取り付けられた窓部材を通してキャビティ２５を視認可能な観察穴２３が形成され、固定型と可動型の離型時に取出部材によって窓部材が可動型から取り出される。【選択図】図１
