The theme of this design is the design， together with its CAD/CAM， of the process and tooling equipment for the rocker shaft bed This design task is from Chaoyang Diesel Engine C， L The purpose of this design is to complete the mold design work for the rocker shaft bed of 195 Diesel Engine， the design of the process flow and process cards for the development of the rocker shaft bed， and the design of some special fixtures for certain We used the Three-dimensional modeling software Pro / E to complete the mould design work， including the modeling work of the parts and blank parts using the part module of the software; the design work of the Investment Casting mold， including the parting surface， the injection systyem， the ejection mechanism， the convex and concave mold， mold base， Completed the mold assembly drawings with engineering drawings module of Pro / E and CAXA Made out the process plan for the part development， including the processing methods， the processing route， the determination of machining allowance， and then calculated the process parameters according to the process plan to produce the process We designed two sets of special milling fixture， one set of special drilling After analysing， selecting， and design， we finished its engineering drawing with CAXA The difficult points of the design are the moulds and We finally solved these problems via a large amount of research work and the teacher's assistance， and successfully accomplished this design Keywords: solid modeling; mold; fixture; technique 完全是自己翻译的，我是搞机械设计的，学习了。谢谢楼主提供的翻译练习机会。
