2個の枠体から抜き枠して無枠式水平割鋳型を造型する無枠式水平割鋳型造型機におけるサンドタンクの砂供給口装置に関する。
【0002】
【従来の技術】
従来、上述したサンドタンクの砂供給口装置のひとつとして、特開平8-132180号公報で開示されるように、サンドタンクの上端に、砂通過孔を有するスライドゲートを水平可能に装着し、かつサンドタンクとスライドゲートとの間にこれらの間をシールするシール部材を配設したものがある。
【0003】
【発明が解決しようとする課題】
しかし、このように構成された従来の砂供給口装置では、シール部材とスライドゲートとの間に鋳物砂が侵入した状態でスライドゲートが往復動されるため、シール部材やスライドゲートは鋳物砂等に削られて早期に摩耗し、しかも、砂通過孔内やスライドゲート上に残留したり、スライドゲートに付着した鋳物砂が、スライドゲートの往復動によって砂供給口装置の外部に飛散したり落下して作業環境を悪化させるなどの問題があった。
【0004】
本発明は上記の事情に鑑みて成されたもので、その目的は、シール部材やスライドゲートが鋳物砂によって摩耗されたり、鋳物砂が砂供給口装置の外部に飛散したり落下することのない無枠式水平割鋳型造型機におけるサンドタンクの砂供給口装置を提供することにある。
【0005】
【課題を解決するための手段】
上記の目的を達成するため本発明の無枠式水平割鋳型造型機におけるサンドタンクの砂供給口装置は、2個の枠体とマッチプレートと2個のスキーズ板とで画成される垂直状態の2個の造型室に充填された鋳物砂を前記2個のスキーズ板によってスキーズしたのち前記2個の枠体から抜き枠をして無枠式水平割鋳型を造型する無枠式水平割鋳型造型機におけるサンドタンクの砂供給口装置であって、前記サンドタンクの上端に気密に装着されてサンドタンクの上端開口部を包囲しかつほぼ中央部に砂供給用開口を有するケーシングと;このケーシング内に水平移動可能に配設されて前記砂供給用開口を開閉しかつほぼ中央部位で2個に分離可能なスライドゲートと;前記ケーシングに装着されて2個の前記スライドゲートをそれぞれ往復動させる2個のアクチュエータと;前記ケーシングに装着されて前記スライドゲートに付着した鋳物砂を除去する除去手段としてのエアノズルと;前記ケーシングに装着されて2個の前記スライドゲートが前記砂供給用開口を閉じた時点で砂供給用開口の周縁と前記スライドゲートとの間を気密にシールするシール部材と;を具備し、
2個の前記スライドゲートは、前記ケーシングの底部に敷設された1対のレール上にV溝付き車輪を介して水平方向へ走行自在に装架したことを特徴とする。
【0006】
このように構成されたものは、スライドゲートに付着等した鋳物砂が除去手段によって取り除かれたのちサンドタンク内に落下する。また、シール部材がスライドゲートとケーシングとの間に配設されていて、これらの間に鋳物砂が侵入することはほとんどない。
【0007】
【発明の実施の形態】
以下、本発明を適用した無枠式水平割鋳型造型機の実施例について図1〜図7に基づき詳細に説明する。図5に示すように、本無枠式水平割鋳型造型機においては、図示しない機台にサンドタンク1が装着してあり、さらに前記機台にはL字状の回動フレーム2が90度上下回動可能にして装着してある。そして、前記サンドタンク1の上端には砂供給口装置3が装着してあり、砂供給口装置3は、特に図1〜図3に示すように、前記サンドタンク1の上端に気密に装着されてサンドタンク1の上端開口部を包囲しかつほぼ中央部に砂供給用開口4を有するケーシング5と、このケーシング5内に水平移動可能に配設されて前記砂供給用開口4を開閉するスライドゲートとしての2分割型のスライドゲート6・6と、このスライドゲート6・6を往復動させるアクチュエータとしての2本のエアシリンダ7・7と、前記スライドゲート6・6に付着した鋳物砂を除去する除去手段としてのエアノズル8・8と、前記スライドゲート6・6が前記砂供給用開口4を閉じた時点で砂供給用開口4の周縁と前記スライドゲート6・6との間を気密にシールするシール部材9とで構成してある。
【0008】
そして、前記ケーシング5は、底部に前記サンドタンク1の上端開口部と同寸の孔を有する箱状のケーシング本体10と、ケーシング本体10の上端開口部を閉鎖しかつ前記砂供給用開口4を有する板状の蓋部材11とで構成してある。また、前記一対のスライドゲート6・6は、前記ケーシング本体10の底部に敷設された1対のレール12・12上にV溝付車輪13・13を介して左右方向へ走行自在に装架してあり、さらに、図4に示すように、相互に接合する部分は凹凸状に形成してありかつシール部材14が埋設してある

【0009】
また、図4に示すように、前記回動フレーム2の左側の垂直部には下枠体15が垂直状態にして装着してあり、さらに前記回動フレーム2の水平部の下方にはこれに沿って延びるガイドバー16が架設してある。また、ガイドバー16には上枠体17と上スキーズ機構18とが垂直状態で摺動自在に装着してあり、前記上枠体17は前記回動フレーム2に固着されたシリンダ(図示せず)の伸縮作動により左右動するようになっている。また、前記上スキーズ機構18は、垂直状態の上スキーズ板19と、上スキーズ板19を支持する支持棒20と、前記ガイドバー16に摺動自在に装着されかつ前記支持棒20を前記ガイドバー16の延びる方向へ摺動自在に貫通させた支持部材21とで構成してあり、前記上スキーズ機構18の支持棒20には後述のスキーズ機構24に係止可能な突起部材23が設けてある。
【0010】
また、前記上・下枠体17・15の下方には前記上スキーズ板19および後述の下スキーズ板28を相互に接近させるスキーズ機構24が別途配設してあり、このスキーズ機構24は、別途固定配設された左右方向へ延びるガイドバー25と、ガイドバー25に摺動自在に装着された移動フレーム26と、移動フレーム26の左部に装着されかつこれに沿って延びる油圧シリンダ27とで構成してあり、油圧シリンダ27の出力ロッドの先端には下スキーズ板28が固着してある。また、前記移動フレーム26の上部には凹みが形成してあって、移動フレーム26の上部右端は、図示する状態では前記上スキーズ機構18の突起部材23に係止できるようになっている。
【0011】
なお、図4における符号29はマッチプレート、、図2における符号30は排気弁である

【0012】
このように構成したものは、図1に示するように、2個のスライドゲート6・6を引き離して砂供給用開口4を開いた状態で、砂供給用開口4から鋳物砂を供給し、鋳物砂の供給後、シリンダ7・7を伸長作動してスライドゲート6・6同士を接近させながら
、エアノズル8・8から圧縮エアを噴出してスライドゲート6・6に付着した鋳物砂を取り除く。取り除かれた鋳物砂はままサンドタンク1内に落下する。そして、図5に示すように、スライドゲート6・6同士を接合して砂供給用開口4を閉じた時点で砂供給用開口4の周縁とスライドゲート6・6との間はシール部材9によって気密にシールされる。
【0013】
次いで、図4に示すように、上・下枠体17・15間にマッチプレート29を搬入したのち、図示しないシリンダを伸長作動して上枠体17を下枠体15に近づけて上・下枠体17・15、マッチプレート29を重合状態にし、重合状態の上・下枠体17・15およびマッチプレート29と、回動フレーム2等を図示しない回転機構をよって90度垂直回転させ、上・下枠体17・15の砂吹き込み口をサンドタンク1の砂噴出孔に接続させる
。次いで、上枠体17の他端開口部内に上スキーズ板19を、また、下枠体15の他端開口部内に下スキーズ板28をそれぞれ若干挿入して、これら上・下枠体17・15、マッチプレート29および上・下スキーズ板19・28によって2個の造型室を画成する。
【0014】
次いで、サンドタンク1に圧縮空気を供給して鋳物砂をサンドタンク1の砂噴出孔から噴出させて2個の造型室にそれぞれ吹き込み充填し、続いて、スキーズ機構24の油圧シリンダ27を伸長作動して上・下スキーズ板19・28を相互に近づけ、2個の造型室内の鋳物砂をスキーズする。
【0015】
こうして、鋳物砂のスキーズ完了後、油圧シリンダ27を収縮作動しかつ図示しないシリンダを作動して上・下スキーズ板19・28を相互に引き離すとともに上・下枠体17・15からそれぞれ抜き出し、続いて、回動フレーム2、上・下枠体17・15、マッチプレート29等を図示しない回転機構をよって90度垂直反転させて上・下枠体17・15
、マッチプレート29等を水平状態に戻す。次いで、上枠体17を一旦上昇させて下枠体15から引き離し、続いて、マッチプレート29を下枠体15から分離する。次いで、上・下枠体17・15を再び近づけてこれらを重ね合わせ、続いて、上・下枠体17・15から上下鋳型を抜き出して一サイクルを終了する。
【0016】
なお、上記の実施例ではスライドゲート6・6は中央部位で2個に分割された構造を成していて、砂供給口装置3は全体として横方向への飛び出しを最小限にしてあるが、これに限定されるものではなく、図6に示すように、スライドゲート36を1個の構造にしても同様の作用効果が得られるのはもちろんである。
【0017】
【発明の効果】
上記の説明から明らかなように、本発明は、2個の枠体とマッチプレートと2個のスキーズ板とで画成される垂直状態の2個の造型室に充填された鋳物砂を前記2個のスキーズ板によってスキーズしたのち前記2個の枠体から抜き枠をして無枠式水平割鋳型を造型する無枠式水平割鋳型造型機におけるサンドタンクの砂供給口装置であって、前記サンドタンクの上端に気密に装着されてサンドタンクの上端開口部を包囲しかつほぼ中央部に砂供給用開口を有するケーシングと;このケーシング内に水平移動可能に配設されて前記砂供給用開口を開閉しかつほぼ中央部位で2個に分離可能なスライドゲートと;前記ケーシングに装着されて2個の前記スライドゲートをそれぞれ往復動させる2個のアクチュエータと;前記ケーシングに装着されて前記スライドゲートに付着した鋳物砂を除去する除去手段としてのエアノズルと;前記ケーシングに装着されて2個の前記スライドゲートが前記砂供給用開口を閉じた時点で砂供給用開口の周縁と前記スライドゲートとの間を気密にシールするシール部材と;を具備し、2個の前記スライドゲートは、前記ケーシングの底部に敷設された1対のレール上にV溝付き車輪を介して水平方向へ走行自在に装架したから、従来のこの種の装置と比較してシール部材やスライドゲートの寿命が長くなり、しかもスライドゲートに付着した鋳物砂が外部に飛散したりすることのないなどの優れた実用的効果を奏する。
