Claims (5)
- 油圧を検出する圧力センサと、この圧力センサから得る圧力検出値と成形機コントローラで設定された圧力指令値に基づいて前記油圧に対するフィードバック制御を行うフィードバック制御回路を備える射出成形機の圧力制御装置において、前記圧力センサの圧力検知面又はこの圧力検知面が臨む油路内に配設して油温を検出する温度センサと、検出した油温により前記圧力センサから得る圧力検出値に対して油温の変動による圧力検出値の変動を相殺する補正を行い、この補正後の圧力検出値を正規の圧力検出値として出力する圧力検出手段とを備えるとともに、前記圧力センサ及び前記フィードバック制御回路を付設した圧力制御弁を備えることを特徴とする射出成形機の圧力制御装置。
- 前記圧力制御弁に、作動油の流入ポート及び流出ポートから遮断された別途の接続ポートを設け、この接続ポートに連通する油路に前記圧力センサを臨ませるとともに、少なくとも前記接続ポートと前記射出シリンダの後油室を所定の配油ラインを介して接続可能に構成することを特徴とする請求項1記載の射出成形機の圧力制御装置。
- 前記温度センサは、前記圧力検知面の近傍に位置する前記油路内に配設することを特徴とする請求項2記載の射出成形機の圧力制御装置。
- 前記圧力センサの圧力検知面は、表面に圧力検出素子を形成した基板を有し、この基板の表面における空スペースに、前記温度センサの温度検出素子を設けることを特徴とする請求項1記載の射出成形機の圧力制御装置。
- 駆動モータの回転数を可変制御して、少なくとも吐出流量を制御可能な油圧ポンプ部を備えることを特徴とする請求項1記載の射出成形機の圧力制御装置。
