摘要
采用消失模工艺生产薄壁壳体铸件 ,常因泡沫模样易变形而导致铸件尺寸超差 ;结合某壳体零件的生产实践 ,介绍了防止泡沫模样变形和减轻铸件变形的几项措施 :如从模具设计、成型工艺和填砂振动紧实参数方面进行控制 。
The thin wall case castings are easily distorted because of the deformation of foam patterns in Lost Foam Porcess Through the practice of producing some case castings,several measures for preventing the deformation of foam patterns and the distortion of casting are introduced in this paper By control from the design of die,the making of foam pattern,the parameters of filling sand and vibrating compaction,it can reduce the casting distortion defect effectly.
