Injection molding machine control system

Abstract

Further optimize the power consumption of injection molding machines. [Solution] A control device for an injection molding machine that repeatedly performs an injection molding cycle including closing the mold, injecting molding material into the mold, holding pressure and cooling, measuring the molding material for the next injection, opening the mold and removing the molded product from the mold, comprising a screw for measuring and a controller for controlling the rotation speed of the screw, wherein the controller comprises a measurable time measuring unit (step S4) that measures and obtains the measurable time, which is the time from the end of holding pressure in a predetermined injection molding cycle to the start of injection in the following injection molding cycle, and a screw rotation speed calculation unit (step S5) that determines the screw rotation speed for measuring based on the measurable time.
