Abstract
【解決手段】 最大型締力(100〔%〕)から所定の大きさを順次低下させた型締力(100〔%〕,80〔%〕,70〔%〕…)により順次型締めして試し成形を行うとともに、金型2の固定型2cを支持する固定盤3c及び金型2の可動型2mを支持する可動盤3mの外面3cf,3mfに付設した型位置センサ4により射出工程における固定盤3cに対する可動盤3mの相対位置(型位置Xc)を検出し、少なくとも、当該型位置Xcに所定の条件を満たす変化が生じたなら当該変化が生じたときの型締力に対して所定の大きさだけ増加させた型締力を適正型締力Fsとして設定する。

Description
Claims (6)
- 型締装置により金型を型締めする際における最大型締力よりも小さい任意の型締力を設定する射出成形機の型締力設定方法において、最大型締力から所定の大きさを順次低下させた型締力により順次型締めして試し成形を行うとともに、金型の固定型を支持する固定盤及び金型の可動型を支持する可動盤の外面に付設した型位置センサにより射出工程における前記固定盤に対する前記可動盤の相対位置(型位置)を検出し、少なくとも、当該型位置に所定の条件を満たす変化が生じたなら当該変化が生じたときの型締力に対して所定の大きさだけ増加させた型締力を適正型締力として設定することを特徴とする射出成形機の型締力設定方法。
- 前記所定の条件を満たす変化は、型締終了時の型位置から所定のオフセット値を減じて設定した下限閾値以下となる変化であることを特徴する請求項1記載の射出成形機の型締力設定方法。
- 前記所定の条件を満たす変化は、型締終了時の型位置に対して所定のオフセット値を加えて設定した上限閾値以上となる変化であることを特徴する請求項1記載の射出成形機の型締力設定方法。
- 前記所定の大きさだけ増加させた型締力には、直前に設定した型締力を用いることを特徴とする請求項1記載の射出成形機の型締力設定方法。
- 前記最大型締力から順次低下させる型締力に対して、低下させる際の限界値を設定し、当該限界値に達しても前記所定の条件を満たす変化が生じないときは、前記限界値を前記適正型締力として設定することを特徴とする請求項1〜4のいずれかに記載の射出成形機の型締力設定方法。
- 前記型位置センサから得る検出信号に対して、フィルタ処理部によりノイズを除去するフィルタリングを行うことを特徴する請求項1〜5のいずれかに記載の射出成形機の型締力設定方法。
