Abstract

PURPOSE:To increase the density of the sand near the molding board and pattern together with that on the upper side of a mold by relatively moving supporting bases for a molding flask superposed with additional flasks on the top and bottom and the molding board respectively below an upper squeeze head thereby placing the molding board into the lower additional flask. CONSTITUTION:A molding board 9 of a shape smaller than the inside size of a molding flask 4 is placed on a lower squeeze head 8. To mold a mold by the pattern 10 placed on the board 9, first upper, lower additional flasks 4a, 4b are positioned on a mold supporting base 3, and the flask 4 is placed. On the other hand, the head 8 is moved upward in such a way that the top surface of the board 9 is made flush to the top surface of the base 3. Thereupon, molding sand is charged into the flasks 4, 4a, 4b and the head 2 is lowered to force the sand slightly downward. Next, the head 8 is forced upward thereby squeezing and molding the sand with the head 8 until the top surface of the board 9 enters the inside of the flask 4b to the position flush with the bottom surface of the flask 4 or slightly below this. Next, the sand is squeezed again by the head 2, whereby the sand density of the entire part is sufficiently increased and the molding is completed.
