Claims (5)
- 樹脂を充填して成形を行った金型の型開き後、突出しロッドを前進させて成形品の離型を行う突出し工程における射出成形機の成形品突出し方法において、前記突出しロッドを最後退位置から予め設定した突出し開始位置まで前進させて一旦停止させる予備前進工程と、この予備前進工程の終了後、前記突出しロッドを前進させて成形品の離型を行う主突出し工程とを含むことを特徴とする射出成形機の成形品突出し方法。
- 移動盤の表面に設置された複数の固定型又は可動型の入替により構成される複数種類の金型に対して順次型締を行う一台の型締装置を使用し、前記突出しロッドの最後退位置は、前記移動盤の裏面から抜脱した位置に設定することを特徴とする請求項1記載の射出成形機の成形品突出し方法。
- 前記固定型又は可動型の入替終了後、次の成形における型締工程の期間に、前記予備前進工程を行うことを特徴とする請求項2記載の射出成形機の成形品突出し方法。
- 前記予備前進工程の終了後であって、前記型締工程の終了後に前記主突出し工程を行うことを特徴とする請求項3記載の射出成形機の成形品突出し方法。
- 前記突出し開始位置は、前記突出しロッドの最後退位置から前記成形品に対する離型開始位置間において任意に変更可能であることを特徴とする請求項1記載の射出成形機の成形品突出し方法。
