Abstract

PURPOSE: To remove molding sand thoroughly from castings and supply the castings a constant posture to the next process by treating the castings cast in vertically split flaskless type molds with a sand cutting device, a suspension supporting device by clamps and a knock-out device while moving these continuously.

CONSTITUTION: A large number of continuous cast molds 1 which cast molten metal in molds of a vertically split flaskless system and are fed in a direction A by a mold feeder 2 are solidified during conveying and in this state, they are fed to the position of a sand ductting device 23. The pawls 26 of the device 23 are inserted into the top surface and upper both sides of the molds reiteratively, by which some parts 27 are cut of sand to expose shoulder parts 3. The parts 3 are supported with bars 19, and when they come to a prescribed position, air cylinders 14, 17 advance so that clamps 13, 18 apply restraining under pressure grasping to the parts 3 and the molds 1 from both sides; at the same time, the speed of the clamp 18 is made faster than that of the 13 to cut the remained molding sand completely owing to the differences in their relative speeds. In the constant posture, the castings are shifted to the next processes of ingate breaking, etc., whereby the working efficiency is improved.
