Abstract

PURPOSE:To decide whether the mulling of molding sand is good or not adequately with one kind of test by pressing a pressing head provided with a wedgelike projection to a test piece made by compacting molding sand, cracking the test piece and measuring the pressing force thereof. CONSTITUTION:A test piece manufactured by compacting molding sand is placed on a vertically moving table 5. When the table 5 is moved upward, the wedgelike projection 10 of a pressing shaft 12 abuts on the test piece, and the projection 10 is pierced into the test piece by the increased repulsive force of a coil spring 15. On the other hand, the shaft 12 is forced upward against the spring 15, and while a magnet pointer 17 comes into contact with a scale plate 16, it moves up ward via a stopper 13. When the projection 10 is pierced deeply on additional increase in the repulsive force of the spring 15, the test piece is cracked vertically. Then, the shaft 12 descends and the pointer 17 sticks to the plate 16, thereby indicating the max. height at which the test piece forced the shaft 12 upward. From the display of the plate 16, the binding force of the molding sand is known, and whether its mulling is good or not is decided.
