[Scope of Claim for Utility Model Registration] In an injection molding machine, a variable displacement pump capable of controlling the flow rate and pressure of oil that drives the injection/pressure holding means that injects and holds the injection molding material; filling process control means for controlling the injection/pressure holding means to move at a predetermined injection speed by outputting a predetermined flow rate command to the variable displacement pump when the pressure means reaches a predetermined position; In the pressure holding process, the pressure holding process control means outputs a pressure command to the variable displacement pump so that a predetermined holding pressure is applied to the injection/pressure holding means for a predetermined pressure holding time. Characteristic process control device for injection molding machines.
