  • Improved molding machine
    Patent number: 5125449
    Abstract: The improved molding machine is constructed such that a match plate having molding portions is clamped between upper and lower molding boxes. Molding sand carried by compressed air is introduced into each of the upper and lower molding boxes. Compressed air (which is devoid of sand) is blown from the under side of the lower molding box so that the molding sand may be evenly deposited on the under surface of the molding portions of the match plate.
