摘要
通过对旋转轴唇形密封圈结构形式分析，论述了油封的密封机理；刃口收缩率的确定；分型面的选取；多腔模具设计；模具材料及技术要求。其中重点介绍和论述油封分型面的选取和多腔模具结构型式。经过多年生产实践验证，本模具结构先进、合理、生产出的多规格油封由于精度高，质量好，提高了密封性能。
With analysizing the structure of rotary shaft oil seal,the paper related to the sealing mechanism of oil seal,the designing of multi-cavity mold,materials for mold and some other technical requirements.It mainly introeduced the choice of seal dividing surface and the structure of multi-cavity mold.practical use proved that the mold structure is advanced and reasenable and products with have a high precision,high quality and improved sealing properties.
