Casting usually according to its casting quality, can be divided into different type of sand casting, special casting and rapid prototyping techniques. Widely used in the production of casting, it has the production process is simple, easy to operate, low cost, production from size limits, do not suffer material performance restrictions. The development of modern foundry industry machinery manufacturing industry is one of the basic technology, so the development of foundry industry marks a national production strength. This design bearing manufactoring technology is casting, this design, understanding the casting process steps, learn to draw casting diagram and the selection principle of parting. Book design work again in the thermal processing referenee based , ”engineering material and forming technology base, ”mechanical design manual” etc material, due to the time and the author level limited, please every reader suggestion. Special thanks to guide teacher LiuWanFu, LiHui give guiding creation, make literature to finish. 绪论 铸造是将液态金属或合金浇注到与零件尺寸、形状相适应的 铸型型腔中，待其冷却凝固后获得毛坯或零件的方法，是机械零 件和毛坯成形的主要工艺方法，铸造毛坏因近乎成形，而达到 免机械加工或少量加工的目的降低了成本并在一定程度 上减少了时间。铸造通常按其铸型型质不同，可分为砂型铸造、 特种铸造和快速成形等方法。铸造在生产中应用广泛，它具有生 产工艺简单，易与操作，成本低，生产不受尺寸限制，不受材料 性能限制。铸造业的发展是现代机械制造工业的基础工艺之一， 因此铸造业的发展标志着一个国家的生产实力。本次设计支座的 制造工艺就是铸造，通过这次设计，了解铸造工艺的步骤，学会 绘铸造图及分型面的选定原则。 本书再设计工作中参考了《热加工工艺基础》、《工程材料及 成形技术基础》、《机械设计手册》等资料，由于时间及作者水平 有限，请各位读者提出宝贵意见。 特别感谢指导老师刘万福、李慧给了指导性创作
