Abstract:First of all, according to provide detail drawings for parts of the technical requirements, material composition, structure characteristics, production conditions, production batch, and performance requirements. Then, analyze the parts of the structure of the casting process, find out the possible structural problems and put forward the measure of improvement measures or prevent defects; According to the structural characteristics of spare parts, technical requirements, production batch, production conditions, select casting and modelling method; The structure characteristics of the parts, put forward a variety of casting and classification scheme, comprehensive comparison and analysis, choose the ideal pouring position and parting surface. Again, according to the characteristics of the casting process and parts, choose the suitable process parameters, designing gating system and map out the casting process. According to the casting process design templates and sand casting process equipment, map casting process diagram, template and box figure.
Keywords: Transmission shaft; casting process design; gating system; casting process chart

第一章 简介
1.1中国古代铸造技术发展
中华文明经历了三个历史阶段：石器时代，青铜时代和铁时代，工具和技术的发明三种材料，与人类的再生产，继续推动人类文明的发展和应用的金属的先进阶段，使人类文明产生了根本的飞跃，铸造工艺和金属的使用密切联系在一起。很多古代的农耕人，铸造技术是一门手艺。根据历史研究，中国的铸造技术开始在夏王朝，已经5000年。中国商超的重875公斤的司母戊方鼎，战国时期的曾候乙尊盘，西汉的投光镜，都是古代铸造的代表作品。早期的铸件大多是农业生产、宗教生活等方面的工具或用具，艺术色彩浓厚。那是的铸造工艺是与陶艺一同发展，受到陶器的影响很大。中国在公元前513年，铸造出了世界上最早见于文字记载的铸铁件 晋国铸型鼎，重约270公斤。到了晚商和西周初期，青铜的铸造技术得到了蓬勃发展，形成了灿烂的青铜文化，遗留到今天的有一批铸造工艺水平较高的铸造产品。 中国古代的铸造方法有：石型即用石头或石膏制作铸型；泥型古称“陶范”；金属型古称“铁范”；失蜡型有出蜡法、走蜡法、脱蜡法或刻蜡法；砂型这种方法是伴随泥型一起产生的。
