Patent ID: 6957687

Claim:
A system for monitoring a molding machine when a sand mold contained in a flask is produced by the molding machine that includes a vertically-movable supporting frame installed across upper ends of frame-setting cylinders mounted on a machine base; a pattern carrier for carrying thereon a pattern plate to a place above a central part of the machine base; an annular leveling frame for surrounding the sides of the pattern plate and for vertical sliding; the flask to be placed on the leveling frame; a sand hopper suspended from the vertically-movable supporting frame, for holding molding sand therein, the sand hopper selectively having an air-ejecting chamber therein to eject an air-jet for aeration by which the molding sand is floated and fluidized; a plurality of squeeze feet disposed at the bottom of the sand hopper, the squeeze feet being controllable to vertically move and stop; sand-charging nozzles disposed around the squeeze feet, for introducing the molding sand from the sand hopper into the flask; a filling frame vertically movably connected to filling-frame cylinders, for surrounding the squeeze feet and the sand-charging nozzles from their outside and for being placed on the flask when moved downwardly; the system comprising: at least one sensor connected to the molding machine for detecting an attribute as required on the molding machine; and a data-analyzing monitor means connected to the sensor, for receiving signals corresponding to the attribute detected by the sensor and analyzing the attribute to display the results of the analysis.
