<p>A pressure control device of an injection molding machine is provided, detects a peak pressure generation time and a peak pressure value of injection pressure, and performs such a pressure control that the injection pressure keeps a detected peak pressure value during the period fro a peak pressure generation time until a time at which a condition of completion of the peak pressure maintenance control is satisfied in a pressure maintaining procedure. Further, a pressure control is performed according to a set pressure of the pressure maintaining procedure during a period from a completion time of a peak pressure maintenance control until a completion time of a pressure maintaining procedure.</p> |
