た射出成形機において、スクリユーの射出ストロ
ーク中の一定の時点における射出シリンダ油圧が
当該時点におけるあらかじめ設定された範囲内の
ものであるかどうかを検出する圧力センサーを設
けて、当該射出シリンダ内の油圧の変化によつて
成形状態を検知するようにしたことを特徴とする
射出成形機における成形状態検知機構。 In an injection molding machine where the injection speed is controlled to be constant by controlling the oil amount, check whether the injection cylinder oil pressure at a certain point during the injection stroke of the screw is within a preset range at that point. 1. A molding state detection mechanism for an injection molding machine, characterized in that a pressure sensor is provided to detect the molding state based on changes in oil pressure within the injection cylinder.
