摘要： A molten metal is poured into and stored in a hopper in a rotary-mold gravity casting process, so that a small amount of the molten metal is allowed to flow out of the hopper into a runner to previously fill up the runner. A casting mold is rotated from this state, thereby causing the molten metal to be filled from the hopper into a cavity by a difference in height generated between the molten metal level in the hopper and the molten metal level in the casting mold. Thus, when the molten metal, once stored in the hopper, is filled into the cavity in the casting mold by rotating the casting mold, the inclusion of air can be prevented from being produced due to ruffling of the molten metal in the cavity.

摘要翻译： 在旋转模具重力铸造工艺中将熔融金属倒入并储存在料斗中，使得少量熔融金属从料斗中流出到流道中，以预先填充流道。 铸造模具从该状态转动，从而通过料斗中的熔融金属水平与铸模中的熔融金属水平之间产生的高度差，使熔融金属从料斗中填充到空腔中。 因此，当通过旋转铸模将一次储存在料斗中的熔融金属填充到铸模中的空腔中时，可以防止由于空腔中的熔融金属的变形而产生空气。
