冒口是指为避免铸件出现缺陷而附加在铸件上方或侧面的补充部分。功能在铸型中,冒口的型腔是存贮液态金属的空腔,在铸件形成时补给金属,有防止缩孔、缩松、排气和集渣的作用,而冒口的主要作用是补缩。冒口的设计功能不同的冒口,其形式、大小和开设位置均不相同。

冒口(riser,rising head)主要是对铸件最后冷却部位的收缩提供金属进行补缩,以便使铸件的缩孔集中在冒口内,故冒口尺寸要足够大,此外,冒口...

The results showed that shrinkage defects of turbochargers could be decreased or eliminated when the modulus difference between riser and casting or the volume ration of riser to casting were increased.
结果表明,增大冒口与铸件的模数之差以及冒口与铸件的体积之比有利于减少及消除涡轮铸件的收缩缺陷。
