Filed: 2002-04-22
Abstract: PROBLEM TO BE SOLVED: To prevent an excess pressure from occurring in a mold in the case of sending a molten resin stored in an injection barrel into the mold by advancing a screw, in an injection molding machine. SOLUTION: A method for controlling the screw advancing speed in the injection molding machine comprises a step of controlling the advancing speed of the screw according to a preset speed pattern until the screw arrives at a deceleration starting position LS4B. The method further comprises the steps of detecting pressures at a plurality of positions in the mold after the screw arrives at the position LS4B (pressure reducing step), and feedback controlling the advancing speed of the screw so that its maximum value arrives at the preset target pressure.  The method also comprises the steps of detecting the pressures of the plurality of the positions in the mold after the screw arrives at the position LS4 (or the dwelling starting time TR2) (dwelling step), and feedback controlling the advancing speed of the screw based on a program control system so as to change its maximum value with respect to the lapse time in the preset pattern. The method also comprises a step of switching the coefficients in the PID arithmetic formula in the case of transferring the decelerating step to the dwelling step.
