Claims (5)
- 射出シリンダの開口を貫通し射出シリンダの中心軸線に沿って往復移動するプランジャによって軽金属成形材料を射出する軽金属射出成形機において、前記開口に設けられ内周面と前記プランジャの外周面との間に間隙を形成し前記間隙において軽金属成形材料を半固化状態に維持する第1の環状体と、前記第1の環状体とリング側面どうしが密接して重なり合うように前記プランジャの移動方向に沿って前記射出シリンダの後端と前記第1の環状体との間に挟まれて前記開口に設けられ内周面の全周にわたって形成される内溝と前記内溝に対して直交する方向に前記内周面に穿たれた複数の横穴と有する第2の環状体と、前記内溝に前記プランジャの周方向に変形可能に収容され前記横穴に流入する溶融軽金属成形材料によって加圧されて全体が均等に縮径し前記プランジャを締め付ける第3の環状体と、を含んでなるシール機構を備えた軽金属射出成形機。
- 前記第2の環状体に設けられる複数の前記横穴が同一形状であることを特徴とする請求項1に記載の軽金属射出成形機。
- 前記第2の環状体に設けられる複数の前記横穴が前記第2の環状体のリング側面から見て円周方向に均等に配置されることを特徴とする請求項1に記載の軽金属射出成形機。
- 前記シール機構が前記第1の環状体の内周面に前記第2の環状体の内周面の前記内溝と合体して一体となる溝を形成する内溝が設けられ前記一体となる溝に前記第3の環状体を収容することを特徴とする請求項1に記載の軽金属射出成形機。
- 前記シール機構において前記第1の環状体の内周面に前記内溝に対して直交する方向に複数の横穴を有し当該横穴が前記第2の環状体に設けられている複数の前記横穴とそれぞれ一体化して1つの穴を形成していることを特徴とする請求項4に記載の軽金属射出成形機。
