【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、水によって除去でき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り、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。
【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を液供給路を介して連通路内に吸引することができる。
なお、この際の当該段差部の近傍とは、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】
【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。
【0022】
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。
【0023】
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。
【0024】
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。
【0025】
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。
【0026】
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。
【0027】
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。
【0028】
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。
【0029】
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。
【0030】
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。
【0031】
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。
【0032】
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。
【0033】
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。
【0034】
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内に侵入するようにしてある。
【0035】
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。
【0036】
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。
【0037】
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。
【0038】
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。
【0039】
次に、処理液供給器具1の使用方法について説明する。
【0040】
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。
【0041】
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。
【0042】
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。
【0043】
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。
【0044】
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。
【0045】
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。
【0046】
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。
【0047】
図16〜図18は、貯液具3の変形例を示したものである。
【0048】
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。

BACKGROUND OF THE INVENTION
The present invention relates to a processing liquid supply apparatus for supplying a processing liquid such as a cleaning agent, a rust preventive, a rust preventive oil, and a rust blackening processing liquid to an internal liquid passage formed inside a mold.
[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 first used as the cleaning liquid, and then, for example, by using an acidic cleaning liquid to which a predetermined amount of hard abrasive is added, the deposition that could not be removed by water is removed. 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]
Patent Document 6 (Japanese Patent Application Laid-Open No. 2000-255493) uses a cooling tank of a mold cooling device to cool a heating cylinder as a means for preventing rust without renewing equipment such as a condenser and a compressor. In the apparatus, a closed liquid circulation circuit having a heat exchange part, a liquid tank and a circulation pump is connected to a cooling water passage of a heating cylinder located at the lower part of the hopper, and the heat exchange part of the liquid circulation circuit is connected We have proposed a method for circulating a coolant with anti-rust properties in a liquid circulation circuit, which is placed in a cooling water tank of an existing mold cooling system.

[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 To change the mold structure, there is a need to change the structure of the mold, the cost of installing new equipment, remodeling the mold, etc., and securing the installation location of the equipment. I had a problem.
[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.
[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 treatment liquid supply path has a structure that communicates with the vicinity of the step portion in the large-diameter passage, the treatment liquid in the reservoir is supplied when the compressed gas flows in the communication path. It can be sucked into the communication path through the passage.
In addition, the vicinity of the said level | step-difference part in this case means the range which becomes negative pressure by the spreading | diffusion when the gas which distribute | circulated the inside of a small diameter passage enters into a large diameter path, and diffuses.
[0014]
Furthermore, it is preferable to provide a changeover switch for opening and closing the liquid supply path. 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 in the opening of the mold internal fluid passage (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]
DETAILED DESCRIPTION OF THE INVENTION
EXAMPLES Hereinafter, although embodiment of this invention is described based on an Example, this invention is not restrict | limited to this Example.
[0022]
As shown in FIG. 1, the processing liquid supply device 1 to the mold internal liquid passage can be composed of a processing liquid supply adapter 2 and a liquid storage device 3.
[0023]
As shown in FIG. 2, the treatment liquid supply adapter 2 forms the injection port receiving portion 4 at one end of the resin-molded main body portion 2A, and forms the mold connection port portion 5 at the other end of the main body portion 2A. A liquid reservoir connecting port portion 6 is formed on the lower surface portion of the main body portion 2A, and a communication passage 7 is formed in the main body portion 2A to communicate between the injection port receiving portion 4 and the mold connection port portion 5, A liquid supply path 8 that communicates between the communication path 7 and the liquid reservoir connection port 6 is formed.
[0024]
The main body 2A is not particularly limited in material, and can be formed from thermoplastic resin, thermosetting resin, rubber, elastomer (resin body having elasticity), etc., but economical and airtight at the time of use. In view of securing the properties, it is preferable to form the material from polypropylene, polyethylene or the like.
The entire processing liquid supply adapter 2 can be integrally formed, but any one of the injection port receiving part 4, the mold connection port part 5, the liquid reservoir connection port part 6, the communication path 7, and the liquid supply path 8. It is also possible to form one or two or more of them from a material different from that of the main body 2A and fix them together to form them integrally. In the case of this example, the liquid storage connection port 6 and the liquid supply path 8 are formed of a material different from that of the main body 2A.
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.
[0025]
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.
[0026]
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.
[0027]
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.
[0028]
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.
[0029]
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.
[0030]
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.
[0031]
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.
[0032]
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.
[0033]
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.
[0034]
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 pipe member 13 penetrates 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 body 15. .
[0035]
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.
[0036]
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.
[0037]
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.
[0038]
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.
[0039]
Next, the usage method of the processing liquid supply instrument 1 will be described.
[0040]
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.
[0041]
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.
[0042]
FIGS. 9-12 shows the modification of the said processing liquid supply instrument 1. FIG.
[0043]
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. The injection port receiving portion 4 is configured by further providing a packing portion 20 for improving airtightness.
[0044]
The packing part 20 of this example is formed integrally with the main body part 2A, spreads outward in a skirt shape with the vicinity of the opening edge of the communication path 7 as the base end part, and is independent of the tapered surface 9a. 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.
[0045]
With 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.
[0046]
