Abstract

PURPOSE:To rationalize molding operation by a method wherein defective molding products are discharged on the way of a carrying-out route in accordance with an error signal output when the defective molding products are injected, thereby to shorten a taking-out cycle. CONSTITUTION:When an error signal ES is issued upon detecting that products are injection-molded out of an allowable range, a control unit is switched from a mode of taking-out program for normal molding products to a mode of discharging program for defective molding products. After taking out the defective molding products from a metal mold, a chuck portion discharges those defective products to above a discharge path (comprising a discharge conveyor, carrying- out chute or so) between a molding machine and an accumulation place for molding products.
