- 为了满足一型多件的要求，并验证常见的浇注设计理论对小型钢铸件的有效性，采用 3 种浇注系统设计理
论即铸造技术手册中提供的公式， Ozan 公式和大孔口出流理论设计了截面形状相似、 尺寸不同的浇注系统， 并用
Magmasoft 进行了模拟。 模拟结果表明，采用大孔口出流理论设计的浇注系统效果较好，并投入生产。 生产结果表明，采
用 1.2∶0.9∶1.0 的直浇道、横浇道、内浇道横截面积比，可获得质量良好的铸件，废品率降低，型板成品率提高 8% 。
To meet the requirements of making multiple castings in one mold and verify the effectiveness of common
gating design theories for small steel casting, three gating systems with similar section shapes and different sizes were
designed with using the three common gating design theories (formula provided in the Foundry Technology Manual, Ozan
Formula and Large Orifice Outflow Theory) and simulated by Magmasoft. The simulated results showed that the gating
system designed using Large Orifice Outflow Theory is better and was put into production. Production results showed that
using cross section area ratio of sprue, runner and ingates at 1.2∶0.9∶1.0, good quality castings are obtained, scrap rate is
reduced, and pattern yield is increased by 8%.
