2、铸出的产品称为铸件。大多数铸件作为毛坯，需要经过机械加工后才能 成为各种机器零件；有的铸件当达到使用的尺寸精度和表面粗糙度要求时，可作为 成品或零件直接应用。 本课程设计是为了获得 ZG270-500 悬臂支架的合理铸造工艺设计方案， 初步设计 悬臂支架的铸造工艺方案，包括选择铸件的浇注位置及分型面，确定型芯的数量、 定位方式、下芯顺序、芯头形状及尺寸，确定工艺参数（如机械加工余量、起模斜 度、铸造圆角级收缩率等）以及浇注系统、冒口、冷铁的形状和尺寸及在砂型中的 布置等，通过 Pro/e 进行仿真，根据模拟结果进行分析，铸造工艺方案的合理性，然 后将所确定的工艺方案用文字和铸造工艺符号在 CA

4、eferred to as casting production, referred to as “casting, casting out products are referred to as casting.As most of the casting blank, need after mechanical processing can be all kinds of machine parts;Some castings when to use the dimensional accuracy and surface roughness requirements, can be di
5、rectly applied as finished products or parts. This course is designed to obtain reasonable ZG270-500 cantilever casting process design, preliminary design of cantilever casting process, including selection of casting pouring position and parting surface, determine the number of cores, positioning wa
