Abstract
A barrel has an injection nozzle at the forward end, and an injection screw inside, and heaters in the outer circumference. The barrel injects the molten resin from the injection nozzle at the forward end by the rotation of the injection screw. In the barrel, the temperatures of each parts are controlled by a temperature control section. A controller sets a shift minus temperature to uniformly lower the temperature of the parts, and a shift absolute temperature to lower the temperatures of the parts to a predetermined temperature. An operation panel section selects the shift minus temperature or shift absolute temperature to lower the temperatures of the parts. The temperature control section lowers the temperatures of the parts of the barrel by using the temperature selected when the injection molding machine is temporarily stopped.
