OPERATION CONTROL METHOD OF INJECTION MOLDING MACHINE

PROBLEM TO BE SOLVED: To easily set (select) whether a composite molded product is discharged to the left-hand or right-hand side of an injection molding machine and to eliminate trouble such that the installation of a molded product-ejecting robot is restricted to one side. SOLUTION: A first operation mode D1 for performing an ejection process Pe for demolding the composite molded product M on and after a mold replacing process Pr for replacing one molds Cam and Cbm by rotating a rotary disc 4 and a second operation mode D2 for performing the mold replacing process Pr on and after the ejection process Pe are provided. When the first operation mode D1 is selected, the composite molded product M demolded in the ejection process Pe is discharged to the right-hand side (or left-hand side) of a machine stand 5 and, when the second operation mode D2 is selected, the composite molded product M demolded in the ejection process Pe is discharged to the left-hand side (right-hand side) of the machine stand 5.
