6. A feed back control of an injection molding machine controlling operational settings of the injection molding machine in a purge mode and a molding mode, comprising:
-
at least one injection speed setting device setting injection speeds depending on whether the injection molding machine is in one of the purge mode and the molding mode; at least one injection pressure setting device setting injection pressures depending on whether the injection molding machine is in one of the purge mode and the molding mode; a switch switching between the at least one injection speed setting device and the at least one injection pressure setting device; an injection unit position device sensing a die close and an injection nozzle touch; and a feed back control switching device switching one of the injection speeds and the injection pressures corresponding to control output signals of at least the at least one injection speed setting device, the at least one injection pressure setting device and the injection unit position device, wherein the injection speeds and the injection pressures are adjusted by feed back control based on whether the injection molding machine is in one of the purge mode and the molding mode.
