"吹吸机风扇注射模设计与模流分析研究"

此文介绍了一项关于吹吸机风扇塑料件的注射模设计和模流分析的研究。首先，根据PA6塑料的工艺特性和产品的使用要求，分析了吹吸机风扇的结构特点和成型工艺。然后，利用Moldflow软件进行模流分析，以确定塑件的注射模结构和工作过程。接着，通过应用PRO/E软件进行3D分模，对模具进行了成型零部件、浇注系统、侧向抽芯机构、推出脱模机构及冷却系统的设计分析。在加载模架时，本设计加载的是国产龙记模架，并利用AutoCAD绘制工程图时利用了Ltools 4.1插件，集成了大量国产模架并提高绘图效率。关键词：吹吸机风扇，注射模设计，模流分析。 Overall, this paper provides a detailed study on the injection mold design and mold flow analysis of a fan used in a suction machine. It begins with an analysis of the structural characteristics and molding process of the fan based on the processing properties of PA6 plastic, the material used for the fan. Moldflow software is then used to conduct a mold flow analysis to determine the injection mold structure and the working process. Subsequently, 3D modeling is performed using PRO/E software to analyze the design of the molding components, the gating system, the lateral core-pulling mechanism, the ejection demolding mechanism, and the cooling system. The design utilizes a domestic Longji mold frame and the Ltools 4.1 plugin in AutoCAD to integrate a large number of domestic mold frames, thereby unifying 3D and 2D design and enhancing drawing efficiency. Keywords: suction machine fan, injection mold design, mold flow analysis.
