INJECTION MOLDING MACHINE WITH AUTOMATIC CONFIGURATION FUNCTION OF METERING PROCESS CONDITION AND CONTROL METHOD THEREOF

摘要

The present invention relates to an injection molding machine capable of automatically setting a metering condition and a control method thereof and, more specifically, to an injection molding machine, capable of effectively suppressing a defect caused by degradation of an injection material and a quality deviation caused by a worker by automatically setting an optimized metering condition for a given mold, and a control method thereof. According to the present invention, provided is a method for automatically setting a metering condition in an injection molding machine (10), comprising: an actual metering time calculation step of calculating, by a control device (100), an actual metering time (RTact) in a first metering process performed according to a set metering speed (RSset) for a given mold; a metering time error calculation step of calculating a metering time error (RTerror) by comparing the actual metering time (RTact) with a predetermined metering time (RTset); and a set metering speed update step of updating the set metering speed (RSset) by performing proportional control by using the metering time error (RTerror), and then performing a subsequent second metering process.
