1、摘 要和传统注塑模具设计方法相比,基于proe和Moldflow的注塑模具设计的设计周期短,成本低并且模具制造工艺性能好。本次毕业设计的零件是挂式空调前盖。首先用计算机辅助软件proe来进行零件的三维造型和注塑模具设计。对设计的零件进行结构与工艺分析,注塑模具设计成三板模,一模一腔,单流道,斜导柱抽芯机构和斜顶抽芯机构,摆钩分型螺钉定距机构。设计成型零部件以及设计合理的推出机构。对设计进行验证主要是对注射机的相关重要参数进行验证,包括模具闭合厚度、模具安装尺寸、模具开模行程、注射机的锁模力等。在校验合格后,进行成型零件加工工艺过程的制定,既要保证塑件的质量,又要兼顾经济性。最后则是模具的装配环
2、节,包括制定装配步骤、明确注意事项等。模具出图环节将使用AutoCAD对装配图和零件图进行修整。然后采用模流分析软件Moldflow对零件进行最佳浇口位置分析和充填+冷却+翘曲分析,根据分析结果对冷却系统和浇注系统进行调整和优化,注塑模具中的浇注系统和冷却系统也进行相应的调整。最后的注塑模具浇注系统合理,流料能够完全充填型腔;冷却系统的冷却效果良好;制品翘曲程度达到合理的范围;模具整体结构合理。关键词:空调前盖;proe;Moldflow;注塑模具AbstractCompared with the traditional injection mold design method, the cy
3、cle of the injection mold design based on the proe, and the Moldflow is short, it cost low and have good mould manufacturing technology. This designs topic is about hang up air conditioning panel parts. First he used computer-assisted software proe to make the molding of parts and plastic injection
4、mold design, then to design of parts structure and process analysis, and the injection mold design use three plate mold, which has a cavity in a mold, work shunt way, font oblique guide column core-pulling mechanism and inclined top core-pulling mechanism, put hook screw spacer institutions parting.
5、 Design molding parts as well as design the launch of the agency. Validate the design to verify the important parameters of the injection machine, including the thickness of the mold is closed, the mold mounting dimensions, mold opening stroke, the injection molding machine clamping force. Calibrati
6、on after passing the formulation of the molding parts machining process, we must ensure the quality of the plastic parts, but also take into account the economy. Finally, there is the link of the mold assembly, including the development of the assembly steps, explicit attention to such matters.He wi
7、ll use the AutoCAD drawing session on the assembly and repair parts diagram. Then use the mold flow analysis software Moldflow to do the analysis of the best parts of gate location and filling + Cooling + warpage analysis, According to the results of analysis of cooling system and pouring system to
