An apparatus for controlling the injection speed ofan injection molding machine |
摘要 |
<p>A method for controlling the injection speed of injection molding machines and an apparatus therefor in which a driving force for forwardly moving an injection plunger movably inserted in an injection cylinder is detected by a first detector; when the value PA detected by the detector exceeds a standard value PSH, the forwardly moving speed of the plunger is controlled to be reduced in accordance with a moving speed reduction control profile VD which is determined by a predetermined decreasing function: further, the forwardly moving speed of the plunger at the dwelling phase switching position is detected by the second detector; the judgment that the value VS detected by the second detector exceeds the upper limit VAH and/or the judgment that the value VS exceeds the lower limit VAL is/are conducted; an alarm signal is outputted when the value VS exceeds the upper limit and/or the value VS exceeds the lower limit.</p> |
