Abstract

PURPOSE:To improve repeating accuracy of changing position by using AC driving control valve, pulse motor driving or servo motor driving control valve to changing control from low speed injection to high speed injection for an injection cylinder. CONSTITUTION:At the time of injection work for the injection cylinder, in the prescribed changing position, by changing from the low speed injection to the high speed injection, the injection work is efficiently executed. In the injection mechanism in the die-casting machine, the AC driving control valve or the pulse motor or the servo motor driving control valve 3 is used to the above changing control. By this method, repeating accuracy at the injection speed changing position is improved to about <=2mm.
