浇注系统是铸型中液态金属进入型腔的通道之总称,基本组元有:浇口杯、直浇道、直浇道窝、横浇道和内浇道。内浇道是液态金属进入铸型型腔的最后一段通道，主要作用：控制金属液充填铸型的速度和方向，调节铸型各部分的温度和铸件的凝固顺序，并对铸件有一定的补缩作用。可以有单个也可以设计多个内浇道。
浇道位置为环形浇道，横浇道设计成扁梯形横浇道，内浇道截面面积根据公式求取。
Ring pouring channel was set for pouring position. Ladder-like horizontal gate was designed for horizontal gate. Section area of ingate was calculated by the equation.
采用薄、宽的内浇道和冷铁工艺消除了飞轮铸件的缩孔缺陷，铸造工艺出品率提高3%；
Using thin, wide ingate and chill can prevent the shrinkage defect, and improve casting yield by 3%.
实际生产表明，改进后的内浇道形成了较理想的流态，使模具温度分布均匀，同时消除了铸件充型远端的冷隔缺陷。
The production verifies that the desirable filling can be formed in the optimized ingate, which plays the uniform temperature distribution in the die and eliminates the cold shut in fi...
