摘要
阐述了陶瓷型精密铸造球墨铸铁子午胎活络模具 ,应用硅橡胶母模制陶瓷型芯 ,负压浇注等新工艺 ,提高模具精度及铸造成品率 ,模具型腔表面粗糙度达 3.2 ,尺寸精度达 1 0 0± 0 .0 6mm ,铸造成品率达 1 0 0 %。
Ceramic precision casting of nodular cast iron radial tire segmented mould was accounted. negative pressure pouring new process was applied to make ceramic core from silicon rubber master pattern. Both accuracy of the mould and ratio of casting finished product were raised. The harshness on the surface of mould cavity reached 3.2, accuracy of measurement was 100±0.06mm, ratio of finished product reached 100%.
