INJECTION MOLDING MACHINE AND CONTROL CIRCUIT FOR INJECTION MOLDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an injection molding machine having excellent responsibility to acceleration/deceleration command to a screw in the injection and capable of molding high quality thin article or precise article with high yield and to provide a control circuit for the injection molding machine.

SOLUTION: In the injection molding machine provided with an injection motor driving circuit for driving an electric servo motor 4 for injection through a servo amplifier 26 for injection control, an injection speed command (vij) to allow the position of the screw 1 to follow an injection position command pattern (xij0) output from a controller 11 and a torque addition value (ta) obtained by multiplying a required constant to the acceleration command pattern (aij0) output from the controller 11 are supplied to the servo pump 26 for injection control.
