Abstract

　成形時に成形品の歪等を防止することができる射出成形装置を提供するために、固定金型６１と可動金型６２とによって形成されたキャビティＣＶ内にゲートＧＡを介して樹脂を射出することにより光学素子を成形する射出成形装置１００であって、ゲートＧＡをキャビティＣＶの中心より下側に配置することを特徴とする。これにより、ゲートＧＡを成形品ＭＰの下側に配置することで樹脂の主な充填方向がゲートＧＡ上方向となり、ゲートＧＡ下側の歪発生を防ぐことができる。また、ゲートＧＡから供給される樹脂が先に射出された樹脂中に射出される状態となり、空気の巻き込みの発生を抑制できるので、酸素による硬化阻害が低減し、短時間で硬化可能となる。
