CASTING APPARATUS AND CASTING METHOD

To provide a casting apparatus and a casting method capable of, while reducing load on a mold and a drive mechanism during closing of the mold, obtaining a cast product with a cast defect suppressed.SOLUTION: In a mold 20 in a casting apparatus 10, a discharge cangue 48 into which a molten metal M flown out from a gap between product cavity forming parts 14a and 14b is disposed at a facing position sandwiching a product cavity 12. At least either of a lower mold 16 and an upper mold 18 includes suction structures 54a and 54b. The suction structures 54a and 54b include: ventilation parts 56a and 56b comprising sand layers 50a and 50b disposed on the product cavity forming parts 14a and 14b; chambers 58a and 58b where the product cavity forming parts 14a and 14b are communicated with each other via the ventilation part 56a and 56b; and decompression mechanisms 60a and 60b which evacuate the chambers 58a and 58b.SELECTED DRAWING: Figure 1 【課題】型閉じ時に鋳型や駆動機構にかかる負荷を低減しつつ、鋳造欠陥が抑制された鋳造製品を得ることができる鋳造装置及び鋳造方法を提供する。【解決手段】鋳造装置１０の鋳型２０には、製品キャビティ形成部１４ａ、１４ｂ同士の間から流出した溶湯Ｍが流入可能な吐かせ４８が、製品キャビティ１２を挟んで対向する位置に設けられている。下型１６及び上型１８の少なくとも一方は、吸引構造５４ａ、５４ｂを有する。吸引構造５４ａ、５４ｂは、製品キャビティ形成部１４ａ、１４ｂに設けられた砂層５０ａ、５０ｂからなる通気部５６ａ、５６ｂと、通気部５６ａ、５６ｂを介して製品キャビティ形成部１４ａ、１４ｂ同士の間に連通するチャンバ５８ａ、５８ｂと、チャンバ５８ａ、５８ｂの内部を減圧する減圧機構６０ａ、６０ｂと、を有している。【選択図】図１
