OPERATION CONTROL METHOD OF INJECTION MOLDING MACHINE

PROBLEM TO BE SOLVED: To shorten a molding time in a case that one molds are successively replaced by rotating a rotary disc to mold a composite molded product and to avoid trouble such that other properties or the like in an individual process are sacrificed even in a case that the molding time is shortened. SOLUTION: A plurality of molds Ca and Cb are arranged between a movable platen 2 and a fixed platen 3 and one molds Cam and Cbm constituting the respective molds Ca and Cb are attached to the rotary disc 4 arranged between the movable platen 2 and the fixed platen 3 are successively replaced by rotating the rotary disc 4 to mold the composite molded product M. At this time, the operation of at least a part of another process performed on and after a mold opening process Po for performing mold opening by allowing the movable platen 2 is performed at the same time in parallel to the operation of the mold opening process Po.
