JIANGSU JIANGSU 本科毕业设计（论文） 本科毕业设计（论文） 中座的铸造工艺设计 摘 要：本文通过对中座的结构、材料、技术要求等的分析，在此基础上设计出符合该零件的树脂砂砂型铸造工艺方案。根据铸造工艺手册和相关资料，确定加工余量、浇注位置、分型面、分模面和铸造缩率等相关参数，并确定采用无冒口浇注方案；根据初步的铸造工艺设计，确定型芯结构、大小和位置；采用铸造CAE，模拟凝固过程中铸件的热节和缩松倾向，设计冷铁的位置和大小以及冒口类型和大小；根据铸造工艺手册，设计铸件的浇注系统，基于半封闭半开放浇注系统的设计方法，设计内浇口、横浇道和内浇口的尺寸和布置；最后对铸件的凝固过程和流动过程进行计算分析，可视化观察了铸件的充型过程，验证了浇注系统的设计。设计出了生产其所要用的模样模板，芯盒等铸造工装图。 关键词：结构分析，工艺设计，模拟分析，工装设计 Of the seat in the casting process design Abstract: This article through to in the structure of the bridge, the material, the technical requirements for analysis, based on this design meets the components of the resin sand sand casting process scheme. According to the casting process manual and related material, sure machining allowance, pouring position, parting surface, parting surface and casting shrinkage and related parameters, and sure to use without rising head pouring scheme, According to preliminary casting process design, fixed type core structure, size and position; The casting CAE simulation, casting during solidification of hot shrinkage section and tendency, design cold iron and take the size and location of the mouth type and size , According to the manual casting process, design casting gating system, based on the semi-closed half open the design of gating system method, ingate design, horizontal runner and ingate size and layout , The last of the castings solidification process and flow process of calculation and analysis, and visualization observed the casting mould filling process, and verifies the the design of gating system , Design the production with the appearance of the template, and core boxes and other casting tooling figure .
