目前在我国中小型铸造车间里,对各种厚壁铸件,如平板类、法兰、轴套、套筒类、实块类以及一些齿轮类、飞轮类等轮类铸件,都普遍地使用压边浇口。 一、压边浇口各组元的确定 1.压边浇口直径φ和高度H 推荐压边浇口高度H=(1.5～2.5)φ,其中大直径取小值,小直径取大值。不同重量铸件推荐用下列压边浇口直径,见表1。 Currently in China’s small and medium-sized foundry, a variety of thick-walled castings, such as flat-panel type, flange, bushings, sleeve type, real class and some gear, flywheel and other wheel castings, are commonly used pressure Side gate. First, the determination of the compaction of each component of the gate 1. Compression edge gate diameter φ and height H Recommended compaction gate height H = (1.5 ~ 2.5) φ, where the large diameter to take small values, small diameter to take large values. Castings of different weights recommend the following gland gate diameter, see Table 1.
