Abstract
This invention relates to flaskless molding equipment for molding a mold that provides support for quickly restoring the stopped equipment to a normal operation. The control circuit (sequencer 200) monitors the movements of the movable members (lower squeezing board 4, lower filling frame 6, upper flask 10, master plate 22, and pushing plate 32), the cylinders (cylinder for squeezing a set of flasks 2, cylinder for a lower filling frame 5, cylinder for upper flask 9, pattern-shuttle cylinder 21, and cylinder for pushing molds 31), and the mechanisms for driving a cylinder (mechanism driving a cylinder for squeezing a set of flasks 400, etc.), and if the period of the operation of each step of the flaskless molding equipment for molding a mold from the start of the operation to the point where the operation of the flaskless molding equipment for molding a mold reaches the predetermined position exceeds the predetermined period that is set to be abnormal, then the control circuit provides support for restoring the stopped equipment to a normal operation, following the instructions displayed on the screen and following the operator's input by means of an input switch.
