Abstract
PURPOSE:To prevent the development of casting blowhole or recessed part on outer face by stretching synthetic resin wire of nylon, etc., in a mold at the time of burning the mold in the pressing casting method for extremely small precise parts of filler for densistry, etc. CONSTITUTION:A Ti ingot 2 in a crucible 1 is melted by arc or high frequency heating and the molten metal is cast into a casting cavity 4 in the mold 3 by the pressing casting method. Then, in order to exhaust air and gas in the casting cavity 4 to casting pressure working direction 1 generating by the pressure difference, at the time of burning the mold 3, the synthetic resin wire of the nylon, etc., is beforehand stretched in the mold 3. By this method. exhausting vents 5... communicating with the casting cavity 4 at the suitable position in the mold 3 is arranged as parallel to the casting pressure direction P or some inclining angle direction, for example about 450 and air and gas in the casting cavity 4 can be instantially exhausted to out of the casting cavity 4 through the vents 5. Therefore, the development of the defect caused by the casting blowhole and misrun can be prevented.
