Abstract

　本発明の課題は、簡易な構成で、前面成形型と後面成形型の軸位置および周方向位置を高精度に位置合わせして、優れた加工精度を得ることの出来る、新規な眼用レンズの製造方法、およびそのような製造方法に好適に用いられる新規な構造の眼用レンズのモールド成形装置を提供することにある。 　かかる課題を解決するために、前後面成形型１６，１８を支持する第一及び第二の冶具１２，１４を非磁性体で形成すると共に、非磁性体で形成された受け部材２０に支持された該冶具１２を該受け部材２０に対して型合わせ方向と略直交する面上の全方向及び回転方向に変位可能とする変位手段３６を設ける一方、該冶具１２に磁石５４を設けると共に、他方の冶具１４及び該受け部材２０の少なくとも一つに磁石５８を設けて、該磁石５４，５８の組による磁気吸引力によって該第一及び第二の冶具１２，１４を周方向で位置決めする周方向位置決め手段３６，５４，５８を設けた。
