Zusammenfassung:	To provide an aluminum-casting metal mold that no molten metal intrudes into a degassing gap when pouring an aluminum molten metal by an electromagnetic pump.SOLUTION: An aluminum-casting metal mold 11 is for an aluminum molten metal pumped up by an electromagnetic pump to be poured therein. The aluminum-casting metal mold 11 comprises a degassing unit 40 for discharging a gas accumulated in a cavity 34, in which an air hole 45 having a size of 30 μm-80 μm is provided in the degassing unit 40.EFFECT: According to the present invention, no molten metal intrudes into the gap if giving a size of 30 μm-80 μm.SELECTED DRAWING: Figure 4 【課題】電磁ポンプでアルミニウムの溶湯を注湯する場合に、ガス抜きのための隙間に溶湯が侵入しないようなアルミ鋳造金型を提供する。【解決手段】電磁ポンプで汲み上げられたアルミニウムの溶湯が、注湯されるアルミ鋳造金型１１であって、このアルミ鋳造金型１１は、キャビティ３４に溜まるガスを排出するガス抜き部４０を備え、このガス抜き部４０に、３０μｍ〜８０μｍの大きさの通気孔４５が設けられている。【効果】３０μｍ〜８０μｍの大きさであれば、隙間に溶湯が侵入しない。【選択図】図４
