Zusammenfassung: | To suppress the clogging of a filter for collecting foreign matters.SOLUTION: A gas suction device (13) comprises: a gas suction part (34) for sucking a gas in a cavity part (14) of a casting die (12); a filter (28) provided between the cavity part and the gas suction part and collecting foreign matters included in a gas from the cavity part; a centrifugal separation part (24) provided between the cavity part and the filter and centrifugally separating the foreign matters included in the gas; and a direction conversion part (26) provided between the centrifugal separation part and the filter and converting the direction of the gas passed through the centrifugal separation part from a first direction (d1) to a second direction (d2) different from the first direction to lead the same to the filter.SELECTED DRAWING: Figure 1
【課題】異物を捕集するフィルタの目詰まりを抑制する。【解決手段】ガス吸引装置(13)は、鋳造金型(12)のキャビティ部(14)内のガスを吸引するためのガス吸引部(34)と、キャビティ部とガス吸引部との間に設けられ、キャビティ部からのガス中に含まれる異物を捕捉するフィルタ(28)と、キャビティ部とフィルタとの間に設けられ、ガス中に含まれる異物をガスから遠心分離する遠心分離部(24)と、遠心分離部とフィルタとの間に設けられ、遠心分離部を通過したガスの方向を第1の方向(d1)から第1の方向と異なる第2の方向(d2)に変換して、フィルタに導く方向変換部(26)と、を備える。【選択図】図1 |
