摘要
介绍塑料模具斜主流道的设计，提出倾斜角是设计的关键，倾斜角与塑料性能有关，对于ＰＥ、ＰＰ 和ＰＡ，倾斜角可达３０°，对ＰＳ、ＳＡＮ 、ＡＢＳ、ＰＣ、ＰＯＭ 和ＰＭ ＭＡ，倾斜角可达２０°，在双斜主流道设计中，应保持相交处为尖角。当主流道偏离中心，采用斜主流道可使顶出容易，减少溢料。
s The design of sloping runner of plastics mould is introduced,pointing out that slope angle is the key point in the design.The slope angle has relation to the property of plastics:for PE,PP and PA,the angle could be 30°,and for PS,SAN,ABS,PC,POM and PMMA,the angle could be 20°.In the design of double sloping runner,the intersection should be a sharp angle.When the main runner departs from the centre,sloping runner could make the knockout easy and reduce flash.
