Abstract
Description
しかも、盤部材に第1補助部材を追加的に固定すると共に金型に第2補助部材を追加的に固定するだけの改造を加えるだけでよいため、金型と盤部材に最小限の工作を施すのみで実施可能できるため、既存の盤部材と金型にも本発明を容易に適用できるうえ、金型や盤部材の一層の汎用性を維持することもできる。
(1)前記テーパ係合凸部は、金型に近づく程小径化するテーパ係合面を有すると共にテーパ係合凸部と一体形成されたフランジを介して盤部材に固定されている。この構成によれば、金型を盤面に接近させる際にテーパ係合凸部による案内機能を得ることができるうえ、テーパ係合凸部は、それと一体のフランジを介して盤部材に簡単に固定することができる。
(3)前記テーパ係合凸部は、第2補助部材に近づく程小径化するテーパ係合面を有すると共にテーパ係合凸部と一体形成されたフランジを介して第1補助部材に固定されている。この構成によれば、(1)と同様の効果が得られる。
本発明は、射出成形機、プレス機、その他の成形機械の盤部材の盤面に金型を盤面と平行方向及び直交方向に位置決めして固定する金型位置決め固定装置に関するものである。
尚、以下の実施例において、盤面と平行方向に位置決めするとは、盤面と平行方向の位置を決めることを意味し、盤面と直交方向に位置決めするとは、盤面と直交方向の位置を決めることを意味する。
図1、図2に示すように、射出成形機1の固定盤2の盤面2aには、固定側金型Mが取り付けられ、図示省略したが可動盤の盤面には可動側金型が取り付けられる。固定側金型M(以下、金型Mという)は、盤面2aに固定される金型基板Maと、この金型基板Maに一体的に固定された金型本体Mbとを有する。射出成形機1の固定盤2の4隅部には、可動盤を案内するガイドロッド4が夫々挿通固定されている。固定盤2の中央孔部には射出ノズルNが突入可能であり、その射出ノズルNから溶融合成樹脂が固定金型Mと可動金型内の成形キャビティ内へ射出されて成形される。
図1~図4、図6に示すように、この第1位置決め機構10Pは、テーパ係合凸部12を有する第1基準部材10と、この第1基準部材10に対向するように金型Mの裏面側部分に装着された第1環状係合部材30などを備えている。
図1、図2、図5、図6に示すように、この第2位置決め機構20Pは、テーパ係合凸部22を有する第2基準部材20と、この第2基準部材20に対向するように金型Mの裏面側部分に装着された第2環状係合部材40などを備えている。
尚、可動盤の盤面に、金型位置決め固定装置3と同様の金型位置決め固定装置によって可動金型が位置決め固定される。
金型Mを盤面2aに接近させ、第1,第2位置決め機構10P,20Pの環状係合部31,41を盤面2a側のテーパ係合凸部12,22に夫々係合させ、クランプ用ボルト9を金型M側のボルト挿通孔7aから挿通させて固定盤2側のボルト孔13,23に螺合させることにより、第1,第2位置決め機構10P,20Pの環状係合部31,41を外径拡大側へ弾性変形させてテーパ係合凸部12,22に夫々密着させることにより、直交方向位置決め機構5Pにより金型Mを盤面2aと直交方向へ位置決めし、第1位置決め機構10Pにより金型Mを盤面2aと平行方向へ位置決めし、第2位置決め機構20Pにより金型Mを第1位置決め機構10Pを中心として盤面2aと平行方向へ回転しないように規制して位置決め固定することができる。
クランプ用ボルト9により金型Mを固定するクランプ力を発生させる構成にしたため、金型位置決め固定装置3の構成を簡単化し、製作費を節減できる。
(1)前記実施例4において、必要に応じて、第1補助部材50を複数のノックピンを介して固定盤2に位置決めすると共に、第2補助部材60を複数のノックピンを介して固定側金型Mに対して位置決めするように構成してもよい。
(2)前記実施例4において、第1,第2補助部材50,60として、複数の第1,第2補助部材を設けることもでき、第1,第2補助部材50,60と、第1,第2基準部材10,20の配置パターンは、図示のものに限定されず、種々の配置パターンを採用することができる。
(4)その他、当業者ならば、本発明の趣旨を逸脱することなく、前記実施例に種々の変更を付加した形態で実施することができる。
