Abstract
PURPOSE:To obtain molding method of a mold that does not use explosion blow and very easy to operate and adjust by hardening casting sand by letting flow high pressure water vapor through the casting sand from the surface of casting sand filled in a molding box on a porous pattern plate. CONSTITUTION:Casting sand S is filled in a molding box 7 placed on a pattern plate 5, and the box 7 containing the sand S is raised by rising of a lift 1. The upper end opening is closed airtightly with a sealing member 9 and a covering member 8 to form a sealed space 10 on the surface of sand S. At tis time, a switching valve 13 is opened for a specified time to introduce 12 high pressure water vapor in a container 14 to the space 10 and let it flow through the sand S, vent plug 6 and small holes 4, 4 successively and discharge to the atmosphere. Consequently, the sand S is shifted in the direction of plugs 6, 6, and high density filling is effected not only in the place of bad sand packing but also along the surface of the plate 5.
