摘　　要：从实践与理论2个方面探讨了消失模浇注系统的设计规范为:铸铁及轻金属铸件宜选用底注、侧注、阶梯注其内浇道形状为扁平,数量宜多,宜水平均布;厚壁铸钢件宜选顶注;控制消失模浇注速度的阻流断面应选在直浇道;直、横、内浇道的断面积应逐渐增大;当浇口经冒口入铸型时浇口长度要短,形状为圆形,以切线方向进入冒口的根部为宜。This article discuss the design criterion of injection systerm of lost foam casting： Cast iron and Light-alloy should casting from botton or side or injection systerm as ladder, the ingate should be flat and number should be more and distributing equality in lever; thick wall cast steel should casting from top; the section which control the velocity of cast should choose on sprue; the area of sprue, runner, ingate should be bigger gradually; when the gate fill the die through riser, the pouring should be short and round, and from the tangent direction to the bottom of the riser.
