Description
射出ノズルの前段部と後段部とに各1個の螺旋溝が形成され、螺旋溝それぞれに、金属製のC−リングが挿入されて固定され、C−リングに両端を固定されて射出ノズルの外周囲に高周波誘導コイルが巻かれ、高周波誘導コイルが、複数個のループ(loop)を備えることを特徴とする。
本発明の非接触高周波誘導加熱によれば、石炭、石油などの化石燃料を使う従来の設備に比べてエネルギー效率が高く、操作が精密にコントロールされるので、高品質の製品が製造でき、また環境汚染を引き起さない、といった多くの利点がある。従って、非接触高周波誘導加熱は、種々の産業分野で広く採用されている。
より具体的に説明すれば、螺旋溝213と高周波誘導コイル211は、さらに螺旋溝213上をセラミックスなどをコーティングした絶縁層214と、高周波誘導コイル211をテフロン(登録商標)(Teflon)などの絶縁樹脂材で覆った被服材215を有している。すなわち、被服材215を有する高周波誘導コイル211を、螺旋溝213の絶縁層214の上に巻いている。また、ランナー212の温度を感知する温度感知センサーライン216は、高周波誘導コイル211と一緒に巻くことができる。
すなわち、螺旋溝213は、前段部、中央部及び後段部の少なくともいずれかに集中的に形成するのが好ましい。言いかえれば、螺旋溝213を、射出ノズル210の前段部、あるいは中央部に集中的に形成するか、あるいは螺旋溝213を、射出ノズル210の前段部と後段部に集中的に形成する。
また、射出ノズル210の前段部は、溶融樹脂射出装置130(図10参照)あるいはマニホルド140(図11参照)から溶融樹脂を直接射出される部分であるので、温度が相対的に高いが、その中央部の温度は、前段部や後段部に比べると相対的に低い。
従って、射出ノズル210の中央部に螺旋溝13を集中的に形成させると、射出ノズル210の全域にかけて温度を均一に高く維持できるという長所がある。
図11の射出ノズル用非接触高周波誘導加熱装置は、溶融樹脂射出装置130が、マニホルド140を挟んで射出ノズル210に連結されている点を除き、図10のものと実質的に同じであり、以下、同じまたは類似の構成に対して同一符号を付けてその差異を中心に説明する。
マニホルド140では、プラスチック製品が製造される時、溶融樹脂射出装置130から流れてきた高温の溶融樹脂が、マニホルド140のランナー141内に溶融状態で連続的に保持され、次いで、ランナー141を通して射出ノズル210に移動してプラスチック射出金型1で製品の成形が行われる。
また、射出ノズルと誘導コイルの間隔が、従来の方法に比べて小さくなり、誘導電力の損失を少なくすることができる。
で通常の知識を有した者ならば誰でも、本発明の技術範囲と精神を逸脱することなく実施形態を変更できる。
