Abstract
PURPOSE:To eliminate crazing pattern on outer surface of the casting and to improve the strength by forming wax layer on the outer surface of lost foam type pattern to form the lost foaming pattern, burying the lost-wax pattern in filling material, pouring molten metal and eliminating the pattern by gasifying. CONSTITUTION:The lost-wax pattern 5 is shaped by forming the wax layer on the outer surface of the lost-wax pattern 1 made of foaming polystyrene, and this lost-wax pattern 5 is buried in the noncombustible filing material 7 charging in a molding flask 6. At the time of pouring the molten metal 11 into a sprue 9 from a furnace 10, the molten metal 11 is flowed while gasifying a runner 8 and reached to the lost- wax pattern 5 to eliminate this by gasifying and flowed in this produced cavity in there, to execute casting. The generated gas is passed through gap of the filing material 7 and flowed into a gas chamber 14 from small holes 13 of gas vent wall 12 and ascended in the chamber 14 and fired by an ignition device 18 after venting the holes 17. Then, when the molten metal 11 is cast by replacing with the lost-wax pattern 5, the molten metal 11 is flowed to the outer surface of the wax layer and cast by replacing it. By this method, development of the crazing pattern can be prevented on the outer face of the casting.
