Air core comes into being because of central minus pressure and goes through the hydrocyclone from the overflowgate to the bottom outlet after the flow field become steady.
其内部由于中心负压而形成空气柱，当流场稳定后，该空气柱从底流口到溢流口贯穿始终。

In this article, ingeniously utilized TAB gate and two times location system and overflow canal, and designed injection mold. Guaranteed well the mold's quality.
本文巧妙地运用了护耳式浇口、二次定位系统及溢流槽来设计模具，更好地保证了塑件质量。
