摘要： After a cavity 2 of a die-casting mold 1 is evacuated to exclude gases, oxygen gas is blown into the cavity 2 until an internal pressure of the cavity exceeds the atmospheric pressure, and then a molten metal 5 is forcibly injected into the cavity 2. The cavity 2 is evacuated to a degree of vacuum less than 100 millibar through a suction nozzle 11. The oxygen gas is blown through a nozzle 14 into the cavity 2 so as to fill the cavity 2 with the oxygen gas at an internal pressure higher than the atmospheric pressure. When the molten metal 5 is injected into the cavity 2 clarified in this way, inclusion of gases is perfectly prohibited. As a result, obtained die-cast products are free from defects such as blowholes or porosity caused by inclusion of gases and so useful as functional members as well as structural members.

摘要： The present invention provides a die-casting method comprising the steps of evacuating a cavity 30 defined by dies of a die-casting machine to provide therein a vacuum of 100 millibar or less during a first period, injecting a reactive gas from a sleeve of the die-casting machine into the cavity 30 during a second period which has a partial overlap period with the first period and follows the overlap period, so as to increase the inner pressure of the cavity to atmospheric pressure or more, pouring a molten aluminum alloy M into the sleeve 40 while keeping the injection of the reactive gas, and subsequently moving a plunger 42 in the sleeve forward to forcibly inject the molten aluminum alloy from the sleeve into the cavity 30 while re-evacuating the cavity 30. The evacuation, reactive-gas injection and re-evacuation operations can be performed with respective overlap periods therebetween. During the operation of supplying the molten aluminum alloy, air and water are effectively discharged to outside, and the reactive gas in an unreacted state is discharged to outside without being incorporated into the molten aluminum alloy. Thus, the present invention provides a die-cast product having a significantly reduced volume of incorporated gases and allows the die-cast product to be applied to functional members.
