随着航空工业的迅速发展,对液压、气动技术提出了更高的要求,O形密封胶圈越来越起着重要的作用,O形胶圈加工的精度也随之不断提高。为此,本文对批量小,种类多,精度要求又高的45°分型面O形胶圈模具在卧式车床上反复实践、探索,总结出了一套成功的加工工艺,并对其产生不合格的原因及排除方法进行分析,供大家参考。一、45°分型面O形胶圈模具结构分析45°分型面O形胶圈压模模具,是由上、下模和定位销组成。上、下模的结合面是45°锥形,结合面中部有压制胶圈的圆弧型腔,型腔侧面有余胶槽,
With the rapid development of the aviation industry, higher requirements are put on the hydraulic and pneumatic technologies. The O-ring is more and more important and the accuracy of the O-ring is continuously increasing. To this end, this article on the small batch, variety, high precision 45 ° sub-surface O-ring mold repeatedly practice in the horizontal lathe, exploration, summed up a set of successful processing technology, and its production Unqualified causes and exclusion methods for analysis, for your reference. First, 45 ° sub-surface O-ring mold structure analysis 45 ° sub-surface O-ring plastic mold, is composed of the upper and lower mold and the positioning pin. Upper and lower die bonding surface is 45 ° taper, the middle of the interface with a pressing apron arc cavity, the cavity side of the plastic tank,
