Abstract

PURPOSE:To obtain a sound casting without any blowhole by injecting molten metal while reducing pressure in a cavity after clamping the die, further filling up the molten metal, cooling and solidifying, and next, cleaning inner part in the cavity by compressed air at the time of opening the die. CONSTITUTION:On the way of injecting the molten metal 3 in the cavity 2, a pressure reducing valve 8 is opened and the pressure in the cavity 2 is reduced through a pressure reducing source 6. When the injection completes, the molten metal 3 is filled up in the cavity 2 and enclosed air is exhausted. Next, after the molten metal 3 cools and solidifies, the casting is taken out. Just after that, the pressure reducing valve 8 is closed and air is blown in the cavity 2 through an air blow valve 9, to clean many kinds of stayed dirts. By this method, the residual dirty material is not mixed in the injection casting and the sound formed product without any hole can be produced.
