Title:
射出成形機の制御方法
Document Type and Number:
Japanese Patent JPWO2004089599
Kind Code:
A1
Abstract:
An injection pressure of an injection molding machine is controlled by a movement of a screw (20). The injection pressure is detected when the screw (20) is moved forward and rearward in an injection process. A rising injection pressure P is predicted in a case where the screw is stopped at a previously set deceleration of the screw from the time of detection of the injection pressure. The predicted rising injection pressure P and a previously set pressure P are compared, and the screw (20) is decelerated at a previously set deceleration based on the comparison result.
