平衡环压铸模CAD设计及CAE成型仿真
中文摘要
首先,分析平衡环压铸件的结构工艺,提出几种不同的压铸工艺方案,计算环形浇口尺寸、弯销尺寸、充填速度、温度、压实压力等工艺参数,完成压铸模结构设计。然后,确定模具分型面和浇注系统,借助PRO/E三维软件,对平衡环零件三维造型,解决模具的结构设计。在此基础上,应用CAE软件PROCAST仿真平衡环充填、凝固过程,优化压铸模具结构设计。再次,绘制模具装配图、零件工程图,同时校核模具关键零件的强度。最后,编制型腔和型芯制造工艺卡片并借助CAM软件完成部分数控加工工序代码的生成。最终表明该模具结构合理,制造工艺良好,工作稳定可靠。

Branch Pipe Joints Die-Casting Mould CAD / CAE
ABSTRACT
In this thesis, firstly, the structures of the Branch Pipe Joints die-casting were analyzed. The structure of die casting die was designed through the analysis of various process planning and the calculations of technological parameters of ring gate, bent pin, speed, temperature, pressure, etc. Secondly, the mold parting surface and gating system must be determined. By using 3D PRO/E software, the die-casting model and the mould structure had been drawn. On the basis, the design of die-casting mould structure was optimized through the application of CAE software PROCAST simulating the pressure filling and solidification course. Then, the Mold assembly drawings, parts drawings were drawn and the key parts intensity was checked. Finally, establish cavity and core manufacturing processes cards using CAM software plete NC code generation of some process. Finally, the conclusions show that the mold structure is reasonable, stable, reliable and the mould has good manufacturing processes.
