Description
図1は、型締め状態の射出成形金型1を示す。基本的には2個の金型板2および3より成り、金型板3から心部材4が突出し、心部材4は、型締め状態で金型板2のキャビティー5内に挿入されている。心部材4およびキャビティー5により、各々1個ずつの金型空腔部6が形成され、これに例えば合成樹脂溶融体が充填される。熔融体はノズル8のホットランナー7を通過して導入され、ゲート9において金型空腔部6内へ射出される。

Claims (8)
- 温度制御された射出成形機械の成形金型(1)のキャビティー(5,5.1)への溶融体の充填終了後に、キャビティー(5,5.1)内の被成形部材の収縮を制御する方法であって、
キャビティー(5,5.1)内の温度および/または内部圧力が監視され、また充填の終了の時点からあるいはキャビティー(5,5.1)内の圧力が最大値(13)となった時点から、射出成形の1サイクルの終結に到るまで金型を温度調節することにより、キャビティー内の温度が基準温度プロファイルを目標とするかまたは内部圧力が基準圧力プロファイルを目標として補正されることを特徴とする被成形部材の収縮を制御する方法。 - キャビティー内の圧力が、常に同一の金型温度において大気圧に達するように温度調節が実行されることを特徴とする請求項1記載の方法。
- 金型温度の検出が、キャビティー(5,5.1)の冷却管路(12)を備えた温度調節循環路(16)の区域で実行されることを特徴とする請求項1または2記載の方法。
- 複数個の温度調節循環路(16)を備えたキャビティー(5.1)において、各々の温度調節循環路(16)の温度は金型内部圧力が大気圧に達した時点で、同一の温度に統一されることを特徴とする請求項1ないし3の何れか1項記載の方法。
- 実際の温度プロファイルおよび/または圧力プロファイルが、各々の基準プロファイルを基準として表示されることを特徴とする請求項1ないし4の何れか1項記載の方法。
- キャビティー(5,5.1)に、あるいはキャビティー(5,5.1)の温度調節循環路(16)に付設された温度センサ(10)および/または内部圧力センサ(20)によりキャビティー(5,5.1)内の温度および/または内部圧力が監視されることを特徴とする請求項1ないし5の何れか1項記載の方法。
- 内部圧力センサ(20)が、ゲート(9ないし9.1)の近傍に、また温度センサ(10)が、溶融体の流通径路の端部に対向して位置することを特徴とする請求項6項記載の方法。
- 複数個の温度調節循環路(16)を備えたキャビティー(5.1)の場合において、少なくとも1つの温度調節循環路(16)にはゲートに近接して1個の圧力センサ(20)が、またすべての温度調節循環路(16)には温度センサ(10)が付設されたことを特徴とする請求項7項記載の方法。
