【０００１】
【発明の属する技術分野】
本発明は、金型内部に形成された内部通液路に洗浄剤、防錆剤、防錆油、錆黒化処理液などの処理液を供給するための処理液供給器具とその蓋具に関する。
【０００２】
【従来の技術】
金型内部には冷却水等を流通させる内部通液路が形成されているが、この内部通液路は一般的に複雑な形状に形成されているため、冷却水等が抜けにくく、内部に溜まって錆が発生しやすい。そこで従来から、金型内部通液路の防錆を図るための様々な処理方法が提案されている。
【０００３】
例えば特許文献１（特開２００２−１４５７号）は、冷却水孔に防錆塗料をポンプ等で注入する方法を開示している。
【０００４】
特許文献２（特開平６−２３４１４５号）は、成形作業を終了した際或いは金型を交換する際に、金型に対する冷却水の供給を遮断し、圧縮空気などの圧力気体を温調装置への流入を規制して金型の循環水路内に供給して循環水路内に溜まった冷却水を排出し、冷却水残留により錆付くのを防止する方法を提案している。
【０００５】
特許文献３（特開平７−２７５８２２号）は、洗浄液タンクから洗浄液を洗浄対象たる液体通路に供給する洗浄液供給路と、該液体通路から排出された洗浄液を該洗浄液タンクへ還流させる洗浄液排出路とを備えた液体通路の洗浄システムにおいて、該洗浄液タンクの該洗浄液を該液体通路と該洗浄液供給路とを介して吸引して該液体通路内に負圧下で該洗浄液を供給するとともに該洗浄液の脈動を発生させる循環手段を該洗浄液排出路に設け、この際、洗浄液として最初に水を用い、次に例えば硬質研磨剤が所定量添加された酸性洗浄液を用いることによって、水で除去されなかった堆積物については酸性液の溶解力と機械的衝撃力により水垢や錆等を除去する方法を提案している。
【０００６】
特許文献４（特開平９−１０９０号）は、水に燐酸、界面活性剤および有機酸誘導体を所定割合で添加して形成した錆除去用の洗浄液を、所要圧力で、樹脂成形用金型の冷却部の一端から供給して他端から排出し、上記金型冷却部の内面に発生した錆を除去すると共に、洗浄液中の燐酸と金型形成材の鉄とが化合した燐酸鉄の防錆被膜を金型冷却部内面に形成することを特徴とする金型冷却部の錆除去方法を提案している。
【０００７】
特許文献５（特開２０００−２８９０３６号）は、金型にゴム材から成る基材０．１〜５０．０ｗｔ％と、有機溶剤５０．０〜９９．９ｗｔ％とを混合して成る防錆剤を塗布して防錆被膜を形成し、金型の保管中は、この防錆被膜が金型から容易に剥離せず、防錆効果を持続可能とし、金型を用いて成形物を形成する際には、防錆被膜は、金型から容易に剥離可能とし、不良品の発生を抑えて経済的な成形を可能とする方法を提案している。
【０００８】
特許文献６（特開２０００−２５４９５３号）は、金型用冷却装置の冷却タンクを利用することにより、コンデンサーやコンプレッサ等の機器をあらためて設備することなく防錆を図る手段として、加熱シリンダーの冷却装置において、ホッパーの下部に位置する加熱シリンダーの冷却用通水路に、熱交換部、液タンク並びに循環用ポンプを備えた密閉式の液体循環回路を接続し、この液体循環回路の熱交換部を既存の金型冷却システムの冷却水タンク内に配置し、液体循環回路に防錆性を備えた冷却液を流通させる方法を提案している。

【発明が解決する課題】
従来、金型内部通液路に洗浄液や防錆液などの処理液を圧送するには、多くの場合、金型内部通液路内に処理液を圧送するための装置を新たに設置する必要があったり、金型の構造を変更する必要があったりし、新たな装置の設置や金型の改造等にかかる費用の点、装置の設置場所の確保などの点で安価かつ簡便に実行するには課題を抱えていた。
【００１１】
そこで本発明は、金型の内部通液路に処理液を送るための処理液供給器具に関し、小型で簡便に扱うことができ、しかも安価に供給することができる、金型内部通液路への処理液供給器具を提供せんとするものである。また、本発明は、処理液供給作業後に、処理液供給器具の保管に適した専用の蓋具を提供せんとするものである。
【００１２】
【課題を解決するための手段】
本発明は、圧縮ガス供給手段の噴射口に接続して使用する金型内部通液路への処理液供給器具であって、
圧縮ガス供給手段の噴射口を略密接状態で当接乃至連結可能な噴射口受部と、金型内部通液路の開口部に挿入乃至連結可能な金型接続口部と、処理液を収容した貯液具を連結可能な貯液具連結口部と、噴射口受部、金型接続口部間を連通する連通路と、当該連通路、貯液具連結口部間を連通し、連通路内に圧縮ガスが流れると内部が負圧になる構成の液供給路とを備えた処理液供給器具（以下、貯液具を除いた構成のものを「処理液供給アダプター」ともいう。）、並びに、当該処理液供給アダプターの貯液具連結口部に貯液具を連結してなる処理液供給器具を提案する。
【００１３】
上記の連通路及び液供給路は、連通路内に圧縮ガスが流れると貯液具内の処理液を液供給路を介して連通路内に吸引し得る構成であるのが好ましい。例えば、前記連通路の中間部に段差部を設け、当該段差部の接続口部側を小径通路とし、当該段差部の処理液噴射口部側を前記小径通路より径の大きな大径通路とし、処理液供給路は、前記大径通路内の当該段差部の近傍に連通してなる構成を備えた構造であれば、連通路内に圧縮ガスが流れると、貯液具内の処理液が液供給路を介して連通路内に吸引され、圧縮ガスとともに連続的に噴射させることができる。
また、貯液具連結口部は、貯液具の連結部内周に接合する筒状の舌片部を設け、当該舌片部に前記液供給路を連通してなる構成を備えた構造であれば、処理液が貯液具から吸引される際に、貯液具連結口部と貯液具の連結口との接合部分から漏れ出すようなことはなく、処理液を漏れなく噴出させることが可能となる。なお、前記段差部の近傍とは、小径通路内を流通してきたガスが大径通路に入って拡散する際、その拡散によって負圧になる範囲を意味している。
【００１４】
更に、液供給路を開閉する切替スイッチを備えているのが好ましい。このような切替スイッチを備えていれば、処理液の噴射と高圧ガスの噴射とを自在に切替えることができ、作業性を一段と高めることができる。
【００１５】
上記「噴射口受部」の構造としては、圧縮ガス供給手段の噴射口を略密接状態で当接乃至連結することが可能で、その際圧縮ガスを漏らさないように連通路内に圧送することができれば特にその構成を限定するものではない。例えば、圧縮ガス供給手段の噴射口を噴射口受部に挿入して嵌着させる構成のもの（例えばガスの元栓口とガスホースの如くワンタッチカプラ式に嵌着するもの）や、ネジ溝を形成して螺合して連結する構成のものなども採用することもできる。
【００１６】
好ましくは、連通路から連続して外側に向って開拡したテーパ面を備えた噴射口受部を挙げることができる。このような噴射口受部であれば、噴射口の径や形状が異なっていても、噴射口をテーパ面に当接すれば略密接状態に接続することができ、しかも、成形機周辺等で既に使われているエアガンなどの圧縮ガス供給手段をそのまま利用して処理を実行することができる。
【００１７】
更に好ましくは、連通路から連続して外側に向って開拡したテーパ面を備えると共に、当該テーパ面の外側に、圧縮ガス供給手段の噴射口を接続する際に当該テーパ面と当該噴射口との間に介在して気密性を高めるパッキン部を備えた噴射口受部を挙げることができる。
このような構成を備えた噴射口受部であれば、圧縮ガス供給手段の噴射口をテーパ面にパッキン部を介在させて当接すなわち押し当てることにより気密性を確実に確保することができる。一般的にテーパ面の角度（図２のα）を大きくすると接続時の気密を確保するのが難しくなるが、このようにパッキン部を介在させる構成とすれば確実に気密を確保することができる。
【００１８】
上記「金型接続口部」の構造は、金型内部通液路の開口部に挿入可能乃至連結可能で、その際圧縮ガス及び処理液を漏らさないように金型内部通液路に圧送できれば特にその構成を限定するものではない。例えば金型内部通液路の開口部に設けられた継手（例えば冷却水ホースを接続するための継手）の開口部に嵌着させる構成のもの（例えばガスの元栓口とガスホースの如くワンタッチカプラ式に嵌着するもの）でもよい。
好ましくは、金型内部通液路の開口部に設けられた継手の開口孔内に挿入可能な挿入部を備え、当該挿入部の先端部で連通路が開口してなる構成を備えた金型接続口部を挙げることができる。このような構成を備えた金型接続口部であれば、継手の開口孔内に挿入するだけで、圧縮ガス及び処理液を漏れなく金型内部通液路内に圧送することができる。
なお、噴射量、噴射形状などを調整し得る噴射調整具を金型接続口部に接続できるように形成することもできる。
【００１９】
上記「貯液具（処理液供給貯液具）」、即ち、上記処理液供給器具の貯液具連結口部に連結して使用する貯液具は、処理液を収容可能で、かつ膨縮可能な貯液具本体と、接続口部とを備え、接続口部から吸引されると貯液具本体が縮むと共に内部の処理液が接続口部から流出する構成を備えたものが好ましい。
このような構成を備えた貯液具であれば、上記処理液供給アダプターに連結して圧縮ガス供給手段からの圧縮ガスを連通路内に流すと液供給路側が負圧となり、貯液具本体内が接続口部から吸引され、本体内の処理液は連通路内に引き出され、圧縮ガスと共に処理液を金型内部通液路へ圧送させることができる。しかもこの際、貯液具はどのような角度で使用しても同様に金型内部通液路内へ処理液を圧送することができる（すなわち天地無用）点でも優れている。
【００２０】
本発明において「圧縮ガス供給手段」とは、コンプレッサ、ポンプ、エアガンなど、圧縮ガスを供給する装置乃至器具（圧縮ガス供給装置乃至器具）を意味し、その「噴射口」とは、圧縮ガス供給装置乃至器具から供給される圧縮ガスを噴射する噴射具の先端部、例えばエアガンに接続された噴射ノズルの先端部に設けられた噴射口などを包含する意である。
また、本発明において「処理液」とは、洗浄液、防錆液、防錆油、錆黒化処理液など、金型内部通液路に何らかの処理を施すための液を意味している。
また、本発明において「噴射口を略密接状態で当接乃至連結可能」の「略密接状態」とは、当接乃至連結した際に圧縮ガス等が漏れないように略隙間なく接続する状態を意味し、「当接」とは嵌合することなく接続する意を、逆に「連結」とは両者が嵌合して接続する意を包含する。
「金型内部通液路の開口部に挿入乃至連結可能」の「挿入」とは、嵌合することなく挿入する意を、逆に「連結」とは両者が嵌合して接続する意を包含する。
【００２１】
上述の如く、本発明の処理液供給器具は、処理液が貯留された貯液具を処理液供給アダプターに連結し、当該アダプターの連通路内に圧縮ガスを吹き込んで処理液を噴出させるものであり、金型内部通液路に処理液を供給する作業終了後は、圧縮ガス供給手段と処理液供給アダプターとの接合を解除し、貯液具を処理液供給アダプターに連結させたままで適当な場所に保管される。この場合、貯液具内に処理液の残余があると、貯液具を傾いていたり横倒しになっていたりすると、処理液供給アダプターの連通路開口端から処理液が漏れ出てしまう。また、処理液によっては、保管中に上記アダプターの連通路が通気孔となって大気に触れることにより、液表面が固まったり変質したりすることもある。
【００２２】
このような、器具保管中の液漏れ及び貯留された処理液の変質防止のため、本発明では、処理液供給器具の金型接続口部の開口端から連通路内に差し入れ可能な太さに形成された軸部の一端に、これよりも幅広の握り部を一体に設けて蓋具を構成し、この蓋具の軸部を使用後の処理液供給器具の連通路に差し込むことで、連通路を閉鎖し、貯液具内が密閉されるようにした。
処理液供給器具への蓋具の装着及び取り外しは、握り部を把持して行える。軸部を連通路に差し込んだとき、軸部よりも幅広の握り部が連通路端部に係合して軸部を連通路内に保持させ、また、握り部で連通路端部が閉塞されることで連通路開口端は閉鎖され、連通路内にゴミや塵埃が進入し付着することも防止できる。
【００２３】
前記構成の蓋具において、連通路を確実に閉鎖するため、連通路の金型接続口部側の大径通路と噴射口受部側の小径通路とに差し入れられるように軸部が形成してあることが好ましい。
より好ましくは、軸部周面に連通路の大径通路内に略一杯に嵌まる大きさの突部と、小径通路内に略一杯に嵌まる大きさの突部を設けて蓋具を構成することができる。このような構成であれば、軸部を連通路内に差し込んだときに、大径、小径両通路の内周面に突部がそれぞれ圧接して通路を確実に遮断し、また、連通路内で軸部が固定されて抜け落ちることもない。また、軸部は、突部が連通路内周面と接し、他の部分と連通路内周面との間は空隙となるため、軸部周面が連通路内周面に張り付くようなこともなく、取り外しも容易に行える。
また、軸部と握り部の接合部分に鍔部を設けて蓋具を構成すれば、蓋具を器具に装着した際に、連通路端部が鍔部で塞がれて軸部が差し入れられた連通路内部を確実に密閉し、通路内にゴミや塵埃が進入し付着することを防止する。
【００２４】
【発明の実施の形態】
以下、実施例に基づいて本発明の実施形態について説明するが、本発明がこの実施例に制限されるものではない。
【００２５】
金型内部通液路への処理液供給器具１は、図１に示すように、処理液供給アダプター２と貯液具３とから構成することができる。
【００２６】
処理液供給アダプター２は、図２に示すように、樹脂成形された本体部２Ａの一端に噴射口受部４を形成し、本体部２Ａの他端に金型接続口部５を形成し、本体部２Ａの下面部には貯液具連結口部６を形成し、本体部２Ａの内部には噴射口受部４、金型接続口部５間を連通する連通路７を形成すると共に、当該連通路７、貯液具連結口部６間を連通する液供給路８を形成して構成してある。
【００２７】
本体部２Ａは、その材料を特に限定するものではなく、熱可塑性樹脂、熱硬化性樹脂、ゴム、エラストマ（弾性を備えた樹脂体）などから形成可能であるが、経済性と使用時の気密性確保等を考慮すると、ポリプロピレン、ポリエチレンなどから形成するのが好ましい。
処理液供給アダプター２全体を一体成形することも可能であるが、噴射口受部４、金型接続口部５、貯液具連結口部６、連通路７、液供給路８のいずれか一つ或いは二つ以上を本体部２Ａとは別の材料から形成し、後から固着して一体に形成することも可能である。本例の場合、貯液具連結口部６及び液供給路８を本体部２Ａとは別材料から形成してある。
また、本体部２Ａは、図１及び図２に示すような角形状や円柱形状、或いは図１１に示すような略円錐形状の如く適宜肉厚形状に形成することも可能であるが、図１０に示すように、金型接続口部５と略連続した円管状に形成することも可能である。
【００２８】
噴射口受部４には、連通路７から連続し、外側に向ってロートの如く開拡したテーパ面９ａを形成してなる噴射口当接開口部９を設けてある。
この際、テーパ面９ａの傾斜角度αは、特に限定するものではないが、３０°〜８０°程度とするのが好ましい。
また、噴射口当接開口部９の開口径は、圧縮ガス供給装置乃至器具に接続された噴射具の先端部、例えばエアガン等の噴射ノズル先端部１０１（この先端部１０１に噴射口を備えている）を挿入可能な大きさであれば特に限定するものではない。
【００２９】
このような噴射口受部４であれば、図３（Ａ）〜（Ｃ）に示すように、例えばエアガン等の噴射ノズル先端部１０１をテーパ面９ａに押し付けて当接すれば、その噴射口を略密接状態に接続することができ、噴射ノズル先端部１０１の噴射口から噴射される圧縮ガスを漏らさないように連通路７内に案内することができる。しかもこの際、噴射ノズル先端部１０１の噴射口を当接する部分をテーパ面９ａとしてあるから、噴射ノズル先端部１０１の径や形状が異なっていても噴射ノズル先端部１０１を略密接状態に当接させることができる。
【００３０】
なお、噴射口受部４は、図１３に示すように、本体部２Ａから突出部２ａを設け、エアガン等の噴射ノズル先端部１０１の噴射口内周面部に設けられたネジ部と螺合し得るネジ部４ａを前記突出部２ａの外周面に形成し、螺合して接続するように形成することもできる。
【００３１】
金型接続口部５は、金型内部通液路５１の開口部５２に挿入可能な挿入部１０を本体部２Ａから突設し、当該挿入部１０の先端部で連通路７を開口させてある。
詳しくは、金型内部通液路５１の開口部５２には、通常、冷却水等を供給するホースを接続するための継手５３が着脱可能に取り付けられるため、この継手５３の開口孔５３ａ内に挿入し得るように挿入部１０を形成してある。
【００３２】
さらに詳しくは、図４に示すように、継手５３の開口孔５３ａ内には段部５３ｂが形成されていることが多く、当該段部５３ｂの奥側が狭くなり小径孔５３ｃとなっているから、挿入部１０はこの小径孔５３ｃ内に挿入可能な長さ及び太さに形成するのが好ましい。
このような金型接続口部５であれば、図４に示すように、継手５３の開口孔５３ａ内奥の小径孔５３ｃ内まで挿入部１０を挿入することができ、連通路７を介して送られて来る処理液を漏れなく金型内部通液路５１内に圧送することができる。開口孔５３ａ内に段部５３ｂがある場合、当該段部５３ｂの奥側まで挿入部１０を挿入しないと処理液が逆に噴出する可能性がある。
なお、継手５３の開口孔５３ａ及びその内部の小径孔５３ｃの径は通常約５ｍｍ〜２０ｍｍ程度であるから、挿入部１０の外径を約５ｍｍ程度とし、かつ長さを約３０ｍｍ程度とすれば、あらゆる継手５３の開口孔５３ａの小径孔５３ｃ内に挿入させることができる。
【００３３】
貯液具連結口部６は、本例の場合、図２に示すように、内周面にネジ部１１ａが刻設されたキャップ体１１の上部を本体部２Ａの下面部に埋設し、キャップ体１１の周側部１１ｂを本体部２Ａの下面部から突出させるようにして構成してある。
但し、本発明における貯液具連結口部は、貯液具３を連結可能であれば、好ましくは着脱自在に連結可能であれば、構造は任意である。
【００３４】
連通路７は、噴射口受部４、金型接続口部５間を連通する穴として形成してあり、詳しくは、図５に示すように、中間部に段差部７ｃを設け、この段差部７ｃの噴射口受部４側をより径小の穴からなる小径通路７ａとし、段差部７ｃの金型接続口部５側をより径大の穴からなる大径通路７ｂとしてある。
具体的な一例としては、段差部７ｃの大きさ、すなわち小径通路７ａと大径通路７ｂの径の差を約５ｍｍ以上とするのが好ましい。
小径通路７ａは、噴射口受部４から段差部７ｃに向って窄まった形状に形成することもできる。
【００３５】
液供給路８は、図５に示すように、連通路７、貯液具連結口部６間を連通路７と略直交するように連通してある。詳しくは、大径通路７ｂ内の段差部７ｃの近傍に連通し、連通路７内に圧縮ガスが流れると液供給路８内が負圧となり、貯液具３内の処理液を吸引し得るように構成してある。
なお、図の例では、段差部７ｃの段差面と液供給路８の噴射口受部４側の内周面が面一になるように液供給路８が連通路７に連通しているが、図１５に示すような段差部７ｃの近傍範囲（図の太線部Ｘ）内であれば連通させることができる。即ち、小径通路７ａ内を流通してきた圧縮ガスが大径通路７ｂに入って一気に拡散した際、その拡散線Ｓの懐部分（点斜線部）が負圧になる範囲であり、当該近傍範囲（図の太線部Ｘ）に液供給路８が連通していれば、連通路７内に圧縮ガスが流れると液供給路８内が負圧となり、貯液具３内の処理液を吸引することができる。
この際、拡散線Ｓの角度αを４５度と想定し、拡散線Ｓが大径通路７ｂの内周面に交わる位置よりも段差部７ｃ寄りの部分を近傍範囲（図の太線部Ｘ）と設定することができる。
【００３６】
要するに、連通路７内に圧縮ガスを流すと貯液具３内の処理液を連通路７内に吸引することができるように形成するためには、連通路７の径を段差部７ｃを介してその金型接続口部５側をより大きくすると共に、連通路７の拡径した大径通路７ｂ内の段差部７ｃ近傍に液供給路８が連結するように構成すればよい。
この際、液供給路８が連通路７に交わる角度は、特に限定するものではなく、本例のように略直交状に交わるように形成することも、又、更にいずれかに傾いた角度で交わるように形成することもできる。
【００３７】
液供給路８の径の大きさは、貯液具３内の処理液を吸引するのに適した適宜大きさに設計するのが好ましい。一般的には、例えば大径通路７ｂの径が約４ｍｍ程度の場合、液供給路８の内径は約１．５ｍｍ程度とするのが好ましい。但し、これに限定されるものではない。
なお、本例の場合、本体部２Ａに穴１２を穿設し、この穴１２内に管部材１３を挿入して固着し、この管部材１３の中空部１３ａ（約１．５ｍｍ）を液供給路８とし、この管部材１３の下端部を上記キャップ体１１の天面を貫いてキャップ体１１内に突入させ、貯液具３を連結すると貯液具本体１５内に進入するようにしてある。
【００３８】
貯液具３は、図６に示すように、処理液を貯液可能で、かつ膨縮可能な貯液具本体１５から構成してある。
【００３９】
この貯液具本体１５は、合成樹脂から形成してあり、伸縮自在な蛇腹状に形成してある胴部１７と、胴部１７上に突出した円管部１８と、円管部１８の上端部に形成された貯液具連結口部６と着脱可能に連結し得る連結部１９とから構成してある。
連結部１９は、貯液具連結口部６のネジ部６ａと螺合可能に形成してある。
【００４０】
このような貯液具３であれば、貯液具連結口部６に連結すると胴部１２内は密閉状態となるが膨縮可能であるから、図７に示すように、貯液具本体１５内に処理液を収納した状態で連結部１９側から吸引されると、貯液具本体１５の胴部１７が縮むと共に、内部の処理液が連結部１９の口から流出する。
また、図示はしないが、貯液具３は、通気穴が無いから３６０°いずれの角度で使用しても、例えば図７の状態から天地逆さで使用しても、同様に処理液を供給することができる。
【００４１】
なお、本例では、貯液具本体１５の胴部を蛇腹状に形成して膨縮自在としてあるが、このような構成に限定するものではない。例えば、ゴム風船の如く素材自体が膨縮自在であってもよい。
また、貯液具３の他の構成も任意に変更可能であり、例えば貯液具本体１５に着脱可能なキャップを装着する構成とすることもできる。
【００４２】
次に、処理液供給器具１の使用方法について説明する。
【００４３】
処理液を収納した貯液具３を、連結部１９を貯液具連結口部６に連結して処理液供給アダプター２に装着して処理液供給器具１を組立てる。
次に、図８に示すように、金型内部通液路５１の開口部５２の継手５３の開口孔５３ａ内、詳しくは開口孔５３ａ内奥の小径孔５３ｃ内に挿入部１０を挿入すると共に、エアガン等の圧縮ガス供給装置乃至器具１００の噴射ノズル先端部１０１を噴射口当接開口部９のテーパ面９ａに押し付けて噴射口受部４と噴射ノズル先端部１０１の噴射口とを略密接状態に接続する。
そして、この接続状態を維持しつつ、圧縮ガス供給装置乃至器具１００を操作して噴射ノズル先端部１０１の噴射口から圧縮ガスを連通路７内を噴射させれば、連通路７内を流通する圧縮ガスによって液供給路８内が負圧となり、貯液具本体１５内は吸引され、貯液具本体１５が収縮すると同時に内部の処理液は液供給路８を通じて連通路７内に流入し、処理液及び圧縮ガスは金型内部通液路５１内に圧送される。
【００４４】
このように、処理液供給器具１を使用すれば、処理液を圧送する装置を新たに設置する必要も、金型を改造する必要もなく、既に金型周辺で使われている圧縮ガス供給装置乃至器具１００を利用するだけで、金型内部通液路５１内に処理液を連続的に圧送することができ、金型内部通液路の処理を簡便に施すことができる。
また、金型５０の金型内部通液路５１の開口部５２は、図８に示すように、水平方向に開口していることは希であり、冷却水等が金型内部通液路５１内に溜まらないように下方或いは斜め下方に開口していることが多いが、本発明の処理液供給器具１であれば３６０°いずれの角度で使用しても、同様に金型内部通液路５１内に処理液を供給することができる。
【００４５】
図９〜図１２は、上記処理液供給器具１の変形例を示したものである。
【００４６】
これらの変形例は、上記処理液供給器具１において、テーパ面９ａの外側に、圧縮ガス供給手段１００の噴射口を当接させる際に当該テーパ面９ａと当該噴射口との間に介在して気密性を高めるパッキン部２０を更に設けて噴射口受部４を構成したものである。
【００４７】
本例のパッキン部２０は、本体部２Ａと一体に形成してあり、連通路７の開口端縁付近を基端部として外側に向ってスカート状に開拡し、かつテーパ面９ａから独立して斜めに起立し、かつ前後に可動可能に形成してある。また、パッキン部２０は、パッキン機能を発揮し得る弾力性を持ち得るように薄く形成してある。この際、肉厚が大きすぎると、たとえポリエチレンなどの柔軟な樹脂でも弾力性が低下してパッキン機能を発揮しないようになる。
なお、パッキン部２０は、パッキン機能を発揮し得る弾力性を持ち得る樹脂、例えばポリエチレン、或いはそれと同等か、それよりも柔軟な樹脂から形成するのが好ましい。よって、上記のように本体部２Ａと一体形成する場合、本体部２Ａもポリエチレン、或いはそれと同等か、それよりも柔軟な樹脂から形成するのが好ましい。
【００４８】
このような噴射口受部４であれば、図１２に示すように、噴射ノズル先端部１０１をパッキン部２０に当接してテーパ面９ａに押付けて、パッキン部２０を介在させて噴射ノズル先端部１０１をテーパ面９ａに接続すれば、気密性を更に高めることができる。しかも、テーパ面９ａの角度（図２のα）が大きくても接続時の気密を確実に確保することができる。
【００４９】
なお、上記の例では、パッキン部２０を本体部２Ａと一体に形成してあるが、別体に形成してもよい。また、本体部２Ａと同じ材質でも別の材質であってもよい。
さらに、上記の例は、言い換えれば薄い樹脂からなる円環状体をテーパ面９ａから独立して起立させて前後可動可能に形成したものであるが、このような円環状体を予めテーパ面９ａに固着して一体に形成することも可能である。なお、この際のパッキン部２０の形状を円環状に限定するものではない。
【００５０】
図１６〜図１８は、貯液具３の変形例を示したものである。
貯液具３は、処理液を収容可能で、かつ膨縮可能な貯液具本体と、連結口部とを備えていれば、上記の例に限定されるものではない。例えば、図１６に示すように、処理液を収容する処理液収容部２３をプラスチックフィルム袋やゴム風船袋等で形成することもできる。この際、処理液収容部２３を支持するため、金属、プラスチックなどからなる保形容器２４内に処理液収容部２３を収納するのが好ましい。このように構成すれば、図１７に示すように、たとえ天地が逆になっても、処理液収容部２３は保形容器２４に支持されるから作業の邪魔になることがない。
また、連結部１４は保形容器２４に設けるのが好ましく、図１８に示すように、処理液収容部２３は保形容器２４に対して着脱可能に構成するのが好ましい。
【００５１】
図１９〜図２２は処理液供給器具１の他の構成例を示したものである。
この構成例の処理液供給アダプター２は、図１９及び図２０に示すように、樹脂により全体が漏斗形に一体成形されてなり、前述した構成のアダプターと同様に、その一端にテーパ面９ａを有する噴射口受部４、他端に金型接続口部５をそれぞれ設けると共に、その下部に貯液具連結口部６を形成し、噴射口部受部４と金型接続口部５を連通路７で連通し、さらに連通路７と貯液具連結口部６とを液供給路８で連通させた形態に構成してある。
【００５２】
連通路７は、図２０に示すように、噴射口受部４側が開口径が小さい小径通路７ａ、金型接続口部５側が開口径が大きい大径通路７ｂとしてあり、両通路が接続する段差部７ｃは、小径通路７ａ端部から大径通路７ｂ端部間をテーパ面７ｄで連続させてなり、このテーパ面７ｄ内から液供給路８を垂下させてある。
【００５３】
また、貯液具連結口部６は、貯液具３の連結部１９外周に一体嵌合し得るように、内周にネジ部１１ａを有する円筒キャップ形をなすと共に、その円筒キャップ部分の下面中央に、貯液具３の連結部１９の内周に接合する筒状の舌片部６１を適宜な長さで一体に突出させ、当該舌片部６１の中央に液供給路８の開口端を設けた形状としてある。
【００５４】
貯液具３は、図２１に示すように、適宜な容量で処理液を貯液可能な伸縮自在な蛇腹状の胴部１７の上面に円管部１８を突出させてなる貯液具本体１５から構成し、円管部１８の上部に、外周面に螺子溝を刻設した連結部１９を設け、この連結部１９の内側は前記筒状舌片部６１がすっぽりと嵌まって接合する空洞状に設けてある。
【００５５】
このように構成された処理液供給器具１は、処理液が入れられた貯液具３を、その連結部１９を貯液具連結口部６に連結して処理液供給アダプター２に装着して組立てられる。この状態で、図２２に示されるように、処理液供給アダプター２の貯液具連結口部６が貯液具３の連結部１９に嵌合して貯液具３の開口を閉鎖し、さらに舌片部６１が連結部１９の内側開口に進入して当該開口内周面に接合する。すなわち、貯液具３の円管部１８の端部開口は、貯液具連結口部６と舌片部６１との二重の壁面で隙間なく閉鎖されて処理液供給アダプター２の下部に一体に取り付けられるため、貯液具３内部の気圧と液供給路８内の気圧とが一定に保たれ、段差部７ｃに負圧が生じたときは、内部処理液を液供給路８を通して連通路７内にスムーズに流出させ、外部に噴出させることができる。この際、貯液具連結口部６との接合部分から処理液が漏れ出すこともない。
【００５６】
図２３は前記各構成の処理液供給器具１に使用される蓋具３０の構成を示したものである。
同図に示すように、蓋具３０は、樹脂成形により、前記連通路７内に差し入れ可能な太さを有していて一端部を先細りとした楊枝形の軸部３１の他端部に、それよりも幅広の握り部３２を一体に設けた形状に構成してある。
【００５７】
詳しくは、軸部３１は、前記金型接続口部５の開口端から連通路７の小径通路７ａの端部に至る長さを有し、その握り部３２側の基部３１１が大径通路７ｂの内径よりも小径、先端部３１２が小径通路７ａの内径よりも小径の太さをなし、基部３１１と先端部３１２は径を徐々に小さくしたテーパ部３１３で連続させた形状となっている。基部３１１は、金型接続口部５の開口端から連通路７の段差部７ｃまでの長さと略同じに設けてある。
【００５８】
また、基部３１１の端部周面には、大径通路７ｂ内に略一杯に嵌まる大きさの環状の突部３１１ａが設けられ、先端部３１２の周面には小径通路７ａ内に略一杯に嵌まる大きさの環状の突部３１２ａが設けられている。これら突部３１１ａ、３１２ａは、それぞれ軸部３１に複数個を適当な間隔を開けて設けたものであってもよい。
【００５９】
さらに、軸部３１と握り部３２の接合部分には、軸部３１と交差して正方形の輪郭に張り出した鍔部３３を一体に設けてある。鍔部３３は、軸部３１を連通路７内に差し込んだときに、当該通路端部に当接して通路を閉鎖するためのものであり、その輪郭は適宜な形状とすることができる。また、握り部３２も、軸部３１よりも幅広であって指先で把持可能であれば、適宜な形状とすることができる。換言すれば、図２５内に点線で示した握り部３１と鍔部３３の形状は、適宜に選定して軸部３１を有する蓋具３０を構成可能である。
【００６０】
このように構成された蓋具３０は、図２４に示すように、処理液供給器具１の保管時、握り部３２を把持して軸部３１を金型接続口部５の開口端から連通路７内に差し込み、処理液供給アダプター２に装着する。差し込まれた軸部３１は、その先端部３１２が小径通路７ａ内、基部３１１が大径通路７ｂ内にそれぞれ挿入され、両通路の内周面に突部３１２ａ、３１１ａが圧接して通路内に固定される。これにより、連通路７は、小径、大径両通路７ａ、７ｂが共に突部３１２ａ、３１１ａにより遮断され、貯液具３の内部から液供給路８、連通路７に渡る空間部は完全に密閉された状態となり、貯液具３内部の処理液を大気に触れさせずに当該器具１を保管することができる。また、蓋具３０により連通路７が閉鎖されるので、保管中に、処理液供給１が横倒しになっても貯液具３内部の処理液が漏れ出すようなことはなく、連通路７内にゴミや塵埃が進入し付着して流通路を目詰まりさせることもない。また、軸部３１を差し入れた状態で、突部３１２ａ、３１１ａ以外の軸部３１の周面と連通路７の内周面との間は隙間となるので、軸部３１を差し入れ及び抜き取る際の接触抵抗が小さく、蓋具３０の装着及び取り外しを容易に行うことができる。

The present invention relates to a treatment liquid supply device for supplying a treatment liquid such as a cleaning agent, a rust prevention agent, a rust prevention oil, and a rust blackening treatment liquid to an internal liquid passage formed inside a mold, and a lid therefor. .
[0002]
[Prior art]
An internal fluid passage for circulating cooling water and the like is formed inside the mold, but this internal fluid passage is generally formed in a complicated shape, so that it is difficult for the cooling water or the like to escape. Rust tends to accumulate. In view of this, various treatment methods have been proposed in the past to prevent rusting of the liquid passage inside the mold.
[0003]
For example, Patent Document 1 (Japanese Patent Laid-Open No. 2002-1457) discloses a method of injecting a rust preventive paint into a cooling water hole by a pump or the like.
[0004]
Patent Document 2 (Japanese Patent Laid-Open No. 6-234145) discloses that when a molding operation is completed or when a mold is replaced, the supply of cooling water to the mold is shut off, and a pressure gas such as compressed air is supplied to the temperature control device. A method is proposed in which the inflow of water is regulated and supplied to the circulating water channel of the mold to discharge the cooling water accumulated in the circulating water channel and prevent rusting due to residual cooling water.
[0005]
Patent Document 3 (Japanese Patent Laid-Open No. 7-275822) discloses a cleaning liquid supply path that supplies a cleaning liquid from a cleaning liquid tank to a liquid passage to be cleaned, and a cleaning liquid discharge path that returns the cleaning liquid discharged from the liquid path to the cleaning liquid tank. In the liquid passage cleaning system, the cleaning liquid in the cleaning liquid tank is sucked through the liquid passage and the cleaning liquid supply passage, and the cleaning liquid is supplied into the liquid passage under a negative pressure, and the pulsation of the cleaning liquid is provided. In this case, water is firstly used as the cleaning liquid, and then, for example, by using an acidic cleaning liquid to which a predetermined amount of a hard abrasive is added, the deposition that has not been removed with water. For materials, we have proposed a method for removing scales and rust by the dissolving power of acidic liquid and mechanical impact force.
[0006]
Patent Document 4 (Japanese Patent Laid-Open No. 9-1090) discloses a rust-removing cleaning solution formed by adding phosphoric acid, a surfactant and an organic acid derivative to water in a predetermined ratio at a required pressure. Supply from one end of the cooling unit and discharge from the other end to remove the rust generated on the inner surface of the mold cooling unit, and rust prevention of iron phosphate combined with phosphoric acid in the cleaning liquid and iron of the mold forming material A method for removing rust from a mold cooling section has been proposed, in which a coating is formed on the inner surface of the mold cooling section.
[0007]
Patent Document 5 (Japanese Patent Laid-Open No. 2000-289036) discloses a rust preventive formed by mixing 0.1 to 50.0 wt% of a base material made of a rubber material in a mold and 50.0 to 99.9 wt% of an organic solvent. A rust preventive film is formed by applying an agent, and during the storage of the mold, this rust preventive film does not peel easily from the mold, making the rust preventive effect sustainable and forming a molded product using the mold. In this case, a method has been proposed in which the anticorrosive coating can be easily peeled off from the mold, and economical molding can be performed while suppressing the occurrence of defective products.
[0008]

[Problems to be solved by the invention]
Conventionally, in order to pressure-feed a processing liquid such as cleaning liquid or rust preventive liquid into the mold internal liquid passage, it is often necessary to install a new device for pumping the processing liquid into the mold internal liquid passage There is a need to change the structure of the mold, and it is cheap and simple in terms of the cost of installing new equipment, remodeling the mold, etc., and securing the installation location of the equipment. Had a challenge.
[0011]
Therefore, the present invention relates to a processing liquid supply device for sending a processing liquid to an internal liquid flow path of a mold, to a mold internal liquid flow path that is small and can be handled easily and can be supplied at a low cost. The processing liquid supply device is provided. In addition, the present invention is to provide a dedicated lid suitable for storing the processing liquid supply device after the processing liquid supply operation.
[0012]
[Means for Solving the Problems]
The present invention is a processing liquid supply instrument to a mold internal liquid passage used to be connected to an injection port of a compressed gas supply means,
Contains the injection port receiving portion that can contact or connect the injection port of the compressed gas supply means in a substantially intimate state, the mold connection port portion that can be inserted or connected to the opening of the liquid passage inside the mold, and the processing liquid. A reservoir connecting port that can connect the stored reservoir, a communication passage that communicates between the injection port receiving portion and the mold connecting port, and a communication passage that communicates between the communication passage and the reservoir connecting port. A processing liquid supply device having a liquid supply path configured to have a negative pressure when a compressed gas flows in the passage (hereinafter, a configuration excluding a liquid storage device is also referred to as a “processing liquid supply adapter”). In addition, a processing liquid supply device is proposed in which a liquid storage device is connected to the liquid storage device connection port of the processing liquid supply adapter.
[0013]
The communication path and the liquid supply path are preferably configured such that when a compressed gas flows through the communication path, the processing liquid in the liquid storage device can be sucked into the communication path via the liquid supply path. For example, a step portion is provided in an intermediate portion of the communication passage, a connection port portion side of the step portion is a small diameter passage, and a treatment liquid ejection port side of the step portion is a large diameter passage having a diameter larger than the small diameter passage, If the processing liquid supply path has a structure having a configuration communicating with the vicinity of the step portion in the large-diameter passage, when the compressed gas flows in the communication path, the processing liquid in the liquid storage device is liquid. It is sucked into the communication path through the supply path and can be continuously injected together with the compressed gas.
In addition, the liquid storage connection port portion may have a structure in which a cylindrical tongue piece joined to the inner periphery of the connection portion of the liquid storage device is provided, and the liquid supply path communicates with the tongue piece. For example, when the processing liquid is sucked from the liquid storage device, the processing liquid is not leaked from the joint portion between the liquid storage device connection port and the liquid storage device connection port, and the processing liquid can be ejected without leakage. It becomes possible. Note that the vicinity of the step portion means a range in which a negative pressure is generated by the diffusion when the gas flowing in the small diameter passage enters the large diameter passage and diffuses.
[0014]
Furthermore, it is preferable that a changeover switch for opening and closing the liquid supply path is provided. If such a changeover switch is provided, it is possible to freely switch between the injection of the processing liquid and the injection of the high-pressure gas, and the workability can be further improved.
[0015]
As the structure of the “injection port receiving portion”, the injection port of the compressed gas supply means can be contacted or connected in a substantially intimate state, and at that time, the compressed gas is pumped into the communication path so as not to leak. If possible, the configuration is not particularly limited. For example, a configuration in which the injection port of the compressed gas supply means is inserted into the injection port receiving part and fitted (for example, a one-touch coupler type fitting such as a gas main plug and a gas hose) or a screw groove is formed. It is also possible to adopt a configuration in which they are screwed together and connected.
[0016]
Preferably, the injection port receiving part provided with the taper surface continuously extended toward the outer side from the communicating path can be mentioned. With such an injection port receiving portion, even if the diameter and shape of the injection port are different, if the injection port is in contact with the tapered surface, it can be connected in a substantially intimate state, and already around the molding machine etc. The processing can be executed using the compressed gas supply means such as an air gun as it is.
[0017]
More preferably, it has a tapered surface that continuously spreads outward from the communication path, and when the injection port of the compressed gas supply means is connected to the outside of the tapered surface, the tapered surface and the injection port There may be mentioned an injection port receiving part provided with a packing part which is interposed between the two and improves airtightness.
In the case of the injection port receiving portion having such a configuration, the air tightness can be reliably ensured by contacting or pressing the injection port of the compressed gas supply means with the packing portion interposed on the tapered surface. In general, when the angle of the tapered surface (α in FIG. 2) is increased, it becomes difficult to ensure airtightness at the time of connection. However, if the packing portion is interposed as described above, airtightness can be reliably ensured. .
[0018]
The structure of the above-mentioned “mold connection port” can be inserted or connected to the opening of the mold internal liquid flow path, and can be pumped to the mold internal liquid flow path so as not to leak the compressed gas and the processing liquid. The configuration is not particularly limited. For example, one-touch coupler type that fits into the opening of a joint (for example, a joint for connecting a cooling water hose) provided at the opening of the liquid passage inside the mold (for example, a gas main plug and a gas hose) It is also possible to fit the
Preferably, a mold having a configuration in which an insertion portion that can be inserted into an opening hole of a joint provided in an opening portion of a mold internal liquid passage is provided, and a communication path is opened at a distal end portion of the insertion portion. A connection port part can be mentioned. If it is a metal mold | die connection opening part provided with such a structure, only by inserting in the opening hole of a coupling, compressed gas and a process liquid can be pumped into a metal mold | die internal flow path without leaking.
In addition, it can also form so that the injection adjustment tool which can adjust injection quantity, an injection shape, etc. can be connected to a metal mold | die connection part.
[0019]
The above-mentioned “liquid storage device (processing liquid supply storage device)”, that is, the liquid storage device used by being connected to the liquid storage device connecting port of the processing liquid supply device can store the processing liquid and expand and contract. It is preferable to include a liquid storage device main body and a connection port portion, and to have a configuration in which the liquid storage device body contracts and the internal processing liquid flows out from the connection port portion when sucked from the connection port portion.
In the case of a liquid storage device having such a configuration, when the compressed gas from the compressed gas supply means is flowed into the communication path by being connected to the processing liquid supply adapter, the liquid supply path side becomes negative pressure, and the liquid storage body The inside is sucked from the connection port, the processing liquid in the main body is drawn into the communication path, and the processing liquid together with the compressed gas can be pumped to the liquid flow path inside the mold. In addition, at this time, the liquid storage device is also excellent in that the treatment liquid can be pumped into the mold internal liquid passage (that is, upside down) regardless of the angle used.
[0020]
In the present invention, “compressed gas supply means” means a device or an instrument (compressed gas supply device or instrument) for supplying compressed gas, such as a compressor, a pump, an air gun, etc. It is intended to include the tip of an injection tool that injects compressed gas supplied from an apparatus or instrument, for example, an injection port provided at the tip of an injection nozzle connected to an air gun.
Further, in the present invention, the “treatment liquid” means a liquid for performing some kind of treatment on the mold internal liquid passage such as a cleaning liquid, a rust prevention liquid, a rust prevention oil, and a rust blackening treatment liquid.
Further, in the present invention, the “substantially close state” in which “the injection port can be contacted or connected in a substantially intimate state” means a state in which the compressed gas or the like is connected without a gap so as not to leak when abutting or connected. It means that “contact” means connection without fitting, and conversely “connection” means both connection and connection.
“Insertion” in “can be inserted into or connected to the opening of the liquid passage inside the mold” means to insert without fitting, and conversely, “to connect” means to connect both by fitting. Include.
[0021]
As described above, the processing liquid supply device of the present invention connects the liquid storage device storing the processing liquid to the processing liquid supply adapter, and blows the processing liquid by blowing compressed gas into the communication path of the adapter. Yes, after the operation of supplying the processing liquid to the mold internal liquid passage is completed, the connection between the compressed gas supply means and the processing liquid supply adapter is released, and the liquid storage device is connected to the processing liquid supply adapter. Stored in place. In this case, if there is residual processing liquid in the liquid storage device, the processing liquid leaks out from the communication channel opening end of the processing liquid supply adapter if the liquid storage device is tilted or laid down. Further, depending on the treatment liquid, the surface of the liquid may be hardened or deteriorated when the communication path of the adapter becomes a vent hole and contacts the atmosphere during storage.
[0022]
In order to prevent such liquid leakage during storage of the instrument and deterioration of the stored processing liquid, in the present invention, the thickness is such that it can be inserted into the communication path from the opening end of the mold connection port of the processing liquid supply instrument. One end of the formed shaft portion is integrally provided with a grip portion wider than this to form a lid, and the shaft portion of this lid is inserted into the communication path of the processing liquid supply device after use. The passage was closed and the inside of the liquid storage device was sealed.
The lid can be attached to and detached from the processing liquid supply device by grasping the grip portion. When the shaft part is inserted into the communication path, the grip part wider than the shaft part engages with the communication path end part to hold the shaft part in the communication path, and the communication path end part is closed by the grip part. As a result, the open end of the communication path is closed, and it is possible to prevent dust and dust from entering and adhering to the communication path.
[0023]
In the lid configured as described above, in order to securely close the communication path, the shaft part is formed so as to be inserted into the large diameter path on the mold connection port side of the communication path and the small diameter path on the injection port receiving part side. Preferably there is.
More preferably, the lid is configured by providing a protrusion having a size that fits almost completely in the large-diameter passage of the communication passage and a protrusion that fits substantially fully in the small-diameter passage on the peripheral surface of the shaft. can do. With such a configuration, when the shaft portion is inserted into the communication passage, the protrusions are pressed against the inner peripheral surfaces of both the large diameter and small diameter passages to reliably block the passage, With the shaft part fixed, it will not fall out. In addition, the shaft part is in contact with the inner peripheral surface of the communication path, and since there is a gap between the other part and the inner peripheral surface of the communication path, the peripheral surface of the shaft part sticks to the inner peripheral surface of the communication path. It can be removed easily.
In addition, if a lid is formed by providing a collar at the joint between the shaft and the grip, the end of the communication path is blocked by the collar when the lid is attached to the instrument, and the shaft is inserted. The inside of the communication passage is securely sealed, and dust and dust are prevented from entering and adhering to the passage.

Further, the main body 2A can be formed in a suitably thick shape such as a square shape or a cylindrical shape as shown in FIGS. 1 and 2, or a substantially conical shape as shown in FIG. As shown in FIG. 5, it is also possible to form a circular tube that is substantially continuous with the mold connection port 5.
[0028]
The injection port receiving portion 4 is provided with an injection port abutting opening 9 that is continuous from the communication path 7 and has a tapered surface 9a that expands outward like a funnel.
At this time, the inclination angle α of the tapered surface 9a is not particularly limited, but is preferably about 30 ° to 80 °.
Further, the opening diameter of the injection port abutting opening 9 is such that the tip of an injection tool connected to a compressed gas supply device or instrument, for example, an injection nozzle tip 101 such as an air gun (the tip 101 is provided with an injection port). The size is not particularly limited as long as the size can be inserted.
[0029]
If it is such an injection port receiving part 4, if the injection nozzle front-end | tip part 101, such as an air gun, is pressed and contact | abutted to the taper surface 9a as shown to FIG. It can be connected in a substantially close state, and can be guided into the communication path 7 so as not to leak the compressed gas injected from the injection port of the injection nozzle tip 101. In addition, at this time, since the portion of the injection nozzle tip 101 that contacts the injection port is a tapered surface 9a, the injection nozzle tip 101 is brought into close contact even if the diameter and shape of the injection nozzle tip 101 are different. Can be made.
[0030]
As shown in FIG. 13, the injection port receiving portion 4 is provided with a protruding portion 2 a from the main body portion 2 </ b> A, and can be screwed with a screw portion provided on the inner peripheral surface portion of the injection nozzle tip 101 of an air gun or the like. It is also possible to form the screw part 4a on the outer peripheral surface of the protruding part 2a and connect it by screwing.
[0031]
The mold connection port portion 5 has an insertion portion 10 that can be inserted into the opening portion 52 of the mold internal liquid passage 51 protruding from the main body portion 2A, and the communication passage 7 is opened at the distal end portion of the insertion portion 10. is there.
Specifically, since a joint 53 for connecting a hose that supplies cooling water or the like is usually detachably attached to the opening 52 of the mold internal liquid passage 51, the joint 53 has an opening 53 a in the joint 53. The insertion part 10 is formed so that it can be inserted.
[0032]
More specifically, as shown in FIG. 4, a stepped portion 53b is often formed in the opening hole 53a of the joint 53, and the back side of the stepped portion 53b is narrowed to form a small diameter hole 53c. The insertion portion 10 is preferably formed to have a length and thickness that can be inserted into the small-diameter hole 53c.
With such a mold connection port portion 5, as shown in FIG. 4, the insertion portion 10 can be inserted into the small-diameter hole 53 c deep inside the opening hole 53 a of the joint 53. The processing liquid that is sent can be pumped into the mold internal liquid passage 51 without leakage. When there is a stepped portion 53b in the opening hole 53a, the processing liquid may be jetted out reversely unless the insertion portion 10 is inserted to the back side of the stepped portion 53b.
In addition, since the diameter of the opening hole 53a of the joint 53 and the small diameter hole 53c in the inside thereof is usually about 5 mm to 20 mm, the outer diameter of the insertion portion 10 is about 5 mm and the length is about 30 mm. , Any joint 53 can be inserted into the small-diameter hole 53c of the opening hole 53a.
[0033]
In the case of this example, as shown in FIG. 2, the liquid reservoir connecting port portion 6 is formed by embedding the upper portion of the cap body 11 in which the screw portion 11a is engraved on the inner peripheral surface in the lower surface portion of the main body portion 2A. The peripheral side portion 11b of the body 11 is configured to protrude from the lower surface portion of the main body portion 2A.
However, the structure of the liquid reservoir connecting port in the present invention is arbitrary as long as the liquid reservoir 3 can be connected, and preferably can be detachably connected.
[0034]
The communication path 7 is formed as a hole that communicates between the injection port receiving portion 4 and the mold connection port portion 5. Specifically, as shown in FIG. 5, a step portion 7 c is provided in the intermediate portion, and this step portion 7c is a small diameter passage 7a made of a smaller diameter hole, and the die connection port 5 side of the stepped portion 7c is a large diameter passage 7b made of a larger diameter hole.
As a specific example, the size of the stepped portion 7c, that is, the difference in diameter between the small diameter passage 7a and the large diameter passage 7b is preferably about 5 mm or more.
The small diameter passage 7a can also be formed in a shape narrowed from the injection port receiving portion 4 toward the stepped portion 7c.
[0035]
As shown in FIG. 5, the liquid supply path 8 communicates between the communication path 7 and the reservoir connecting port 6 so as to be substantially orthogonal to the communication path 7. In detail, it communicates with the vicinity of the stepped portion 7c in the large-diameter passage 7b, and when the compressed gas flows in the communication passage 7, the inside of the liquid supply passage 8 becomes negative pressure and the processing liquid in the liquid storage device 3 can be sucked. It is constituted as follows.
In the example shown in the figure, the liquid supply path 8 communicates with the communication path 7 so that the stepped surface of the stepped portion 7c and the inner peripheral surface of the liquid supply path 8 on the injection port receiving portion 4 side are flush with each other. As long as it is in the vicinity of the stepped portion 7c (thick line portion X in the figure) as shown in FIG. That is, when the compressed gas flowing through the small-diameter passage 7a enters the large-diameter passage 7b and diffuses all at once, the nose portion (dotted line portion) of the diffusion line S becomes a negative pressure, and the vicinity range ( If the liquid supply path 8 communicates with the thick line portion X) in the figure, when the compressed gas flows in the communication path 7, the liquid supply path 8 becomes negative pressure, and the processing liquid in the liquid storage device 3 is sucked. Can do.
At this time, assuming that the angle α of the diffusion line S is 45 degrees, a portion closer to the stepped portion 7c than the position where the diffusion line S intersects the inner peripheral surface of the large-diameter passage 7b is referred to as a neighborhood range (thick line portion X in the figure). Can be set.
[0036]
In short, in order to form so that the processing liquid in the liquid storage device 3 can be sucked into the communication path 7 when a compressed gas is caused to flow through the communication path 7, the diameter of the communication path 7 is set via the step portion 7c. What is necessary is just to comprise so that the liquid supply path 8 may be connected to the level | step-difference part 7c vicinity in the large diameter channel | path 7b where the diameter of the metal connection port part 5 side is enlarged more, and the communicating path 7 is expanded.
At this time, the angle at which the liquid supply path 8 intersects the communication path 7 is not particularly limited, and the liquid supply path 8 may be formed to intersect substantially orthogonally as in this example, or at an angle that is further inclined. It can also be formed to intersect.
[0037]
The size of the diameter of the liquid supply path 8 is preferably designed to an appropriate size suitable for sucking the processing liquid in the liquid storage device 3. Generally, for example, when the diameter of the large-diameter passage 7b is about 4 mm, the inner diameter of the liquid supply passage 8 is preferably about 1.5 mm. However, it is not limited to this.
In the case of this example, a hole 12 is formed in the main body 2A, and a tube member 13 is inserted and fixed in the hole 12, and the hollow portion 13a (about 1.5 mm) of the tube member 13 is supplied with liquid. A path 8 is formed, and the lower end portion of the tube member 13 penetrates through the top surface of the cap body 11 and enters the cap body 11. When the liquid storage device 3 is connected, the pipe member 13 enters the liquid storage device main body 15. .
[0038]
As shown in FIG. 6, the liquid reservoir 3 includes a liquid reservoir main body 15 that can store a treatment liquid and that can expand and contract.
[0039]
The liquid storage device main body 15 is made of a synthetic resin, and has a barrel portion 17 formed in a stretchable bellows shape, a circular pipe portion 18 protruding on the trunk portion 17, and an upper end of the circular pipe portion 18. It is comprised from the connection part 19 which can be connected with the liquid storage apparatus connection port part 6 formed in the part so that attachment or detachment is possible.
The connecting portion 19 is formed so as to be screwable with the screw portion 6 a of the liquid storage device connecting port portion 6.
[0040]
With such a liquid storage device 3, the body 12 is sealed when connected to the liquid storage connection port 6, but can be expanded and contracted. Therefore, as shown in FIG. When the processing liquid is sucked in from the connecting portion 19 side, the body portion 17 of the liquid storage device main body 15 is contracted and the processing liquid inside flows out from the opening of the connecting portion 19.
Although not shown, since the liquid storage device 3 does not have a vent hole, it can be used to supply the treatment liquid even if it is used at any angle of 360 °, for example, upside down from the state shown in FIG. be able to.
[0041]
In this example, the body portion of the liquid storage device main body 15 is formed in a bellows shape so as to be freely expandable and contractible, but is not limited to such a configuration. For example, the material itself may be freely expandable and contractible like a rubber balloon.
Moreover, the other structure of the liquid storage device 3 can also be changed arbitrarily, for example, it can also be set as the structure which attaches the cap which can be attached or detached to the liquid storage device main body 15. FIG.
[0042]
Next, the usage method of the processing liquid supply instrument 1 will be described.
[0043]
The liquid storage device 3 containing the processing liquid is connected to the liquid storage device connecting port portion 6 with the connecting portion 19 connected to the processing liquid supply adapter 2 to assemble the processing liquid supply device 1.
Next, as shown in FIG. 8, the insertion portion 10 is inserted into the opening hole 53a of the joint 53 of the opening 52 of the mold internal fluid passage 51, specifically, into the small diameter hole 53c at the back of the opening hole 53a. The injection nozzle tip 101 of the compressed gas supply device such as an air gun or the instrument 100 is pressed against the tapered surface 9a of the injection nozzle contact opening 9 so that the injection nozzle receptacle 4 and the injection nozzle of the injection nozzle tip 101 are substantially in close contact with each other. Connect to the state.
Then, while maintaining this connected state, if the compressed gas supply device or the instrument 100 is operated to inject the compressed gas into the communication passage 7 from the injection port of the injection nozzle tip 101, the communication passage 7 is circulated. Due to the compressed gas, the inside of the liquid supply passage 8 becomes negative pressure, the inside of the liquid storage device main body 15 is sucked and the liquid storage device main body 15 contracts, and at the same time, the internal processing liquid flows into the communication passage 7 through the liquid supply passage 8. The processing liquid and the compressed gas are pumped into the mold internal liquid passage 51.
[0044]
In this way, if the processing liquid supply apparatus 1 is used, there is no need to newly install a device for pumping the processing liquid, and there is no need to modify the mold, and the compressed gas supply apparatus already used around the mold. The processing liquid can be continuously pumped into the mold internal fluid passage 51 simply by using the tool 100, and the mold internal fluid passage can be easily processed.
Further, as shown in FIG. 8, the opening 52 of the mold internal liquid passage 51 of the mold 50 rarely opens in the horizontal direction, and cooling water or the like is rarely opened in the mold internal liquid passage 51. In many cases, it is opened downward or obliquely downward so that it does not accumulate in the interior. However, in the case of the processing liquid supply apparatus 1 of the present invention, even if it is used at any angle of 360 °, the liquid flow path inside the mold is the same. The processing liquid can be supplied into the 51.
[0045]
FIGS. 9-12 shows the modification of the said processing liquid supply instrument 1. FIG.
[0046]
These modifications are provided between the tapered surface 9a and the injection port when the injection port of the compressed gas supply means 100 is brought into contact with the outside of the tapered surface 9a in the processing liquid supply instrument 1.

It stands up diagonally and is movable forward and backward. Moreover, the packing part 20 is formed thinly so that it may have the elasticity which can exhibit a packing function. At this time, if the wall thickness is too large, even if a flexible resin such as polyethylene is used, the elasticity is lowered and the packing function is not exhibited.
In addition, it is preferable to form the packing part 20 from resin which can have the elasticity which can exhibit a packing function, for example, polyethylene, or the resin which is equivalent or more flexible than it. Therefore, when integrally forming with 2 A of main-body parts as mentioned above, it is preferable to form 2 A of main-body parts also from polyethylene or the resin which is equivalent or more flexible than it.
[0048]
In the case of such an injection port receiving portion 4, as shown in FIG. 12, the injection nozzle tip 101 is brought into contact with the packing portion 20 and pressed against the tapered surface 9a, and the injection nozzle tip is interposed with the packing portion 20 interposed therebetween. If 101 is connected to the taper surface 9a, the airtightness can be further enhanced. Moreover, even when the angle of the tapered surface 9a (α in FIG. 2) is large, it is possible to ensure airtightness at the time of connection.
[0049]
In the above example, the packing portion 20 is formed integrally with the main body portion 2A, but may be formed separately. Moreover, the same material as the main body 2A or a different material may be used.
Furthermore, in the above example, an annular body made of a thin resin is formed so as to be able to move back and forth independently from the tapered surface 9a, but such an annular body is previously formed on the tapered surface 9a. It is also possible to fix and integrally form. In addition, the shape of the packing part 20 in this case is not limited to an annular shape.

At this time, in order to support the processing liquid storage unit 23, it is preferable to store the processing liquid storage unit 23 in a shape retaining container 24 made of metal, plastic or the like. With this configuration, as shown in FIG. 17, even if the top and bottom are reversed, the processing liquid storage unit 23 is supported by the shape-retaining container 24, so that it does not interfere with the work.
Moreover, it is preferable to provide the connection part 14 in the shape-keeping container 24, and it is preferable to comprise the process liquid storage part 23 so that attachment or detachment with respect to the shape-keeping container 24 is possible, as shown in FIG.

In this state, as shown in FIG. 22, the reservoir connecting port 6 of the treatment liquid supply adapter 2 is fitted into the connecting portion 19 of the reservoir 3 to close the opening of the reservoir 3, and The tongue piece portion 61 enters the inner opening of the connecting portion 19 and is joined to the inner peripheral surface of the opening. That is, the end opening of the circular pipe portion 18 of the liquid storage device 3 is closed without a gap by the double wall surface of the liquid storage device connection port portion 6 and the tongue piece portion 61 and integrated with the lower portion of the processing liquid supply adapter 2. Therefore, when the air pressure inside the liquid storage device 3 and the air pressure inside the liquid supply path 8 are kept constant and a negative pressure is generated in the stepped portion 7 c, the internal processing liquid is communicated through the liquid supply path 8. 7 can smoothly flow out and be ejected to the outside. At this time, the processing liquid does not leak from the joint portion with the liquid storage device connecting port 6.
[0056]
FIG. 23 shows the configuration of the lid 30 used in the processing liquid supply device 1 having the above-described configuration.
As shown in the figure, the lid 30 has a thickness that can be inserted into the communication path 7 by resin molding, and the other end of the toothpick-shaped shaft portion 31 having one end tapered. The grip part 32 having a wider width than that is integrally formed.
