摘　　要：针对缸盖样件经常出现的气孔、缩松等问题,研究了发动机缸盖样件的真空增压快速铸造技术。通过对缸盖样件关键部位组织观察和不同位置的二次枝晶间距测量,发现该工艺满足发动机缸盖的性能设计要求,不仅可以实现铸件的顺序凝固,致密度提高,而且节省了时间和成本,为发动机缸盖快速成形提供了一种新的工艺选择。Aimed at the problems of pore, shrinkage, non-directional solidification etc. in engine cylinder head sample, the vacuum pressurizing rapid casting technology for engine cylinder head samples was investigated to reduce the defects.From the microstructure observation about key parts of cylinder head samples and the measurement of the secondary dendrite spacing in different position, this technology can meet the requirements of the engine performance design. This technology provides a new technology chose for producing engine cylinder head, because it can not only realize sequence casting solidification, enhance density, but also save the time and cost.
