小电机外壳造型和注射模具设计及CAE分析 摘要：注射模具是生产各种工业产品的重要工艺装备在模具加工前，在计算机上对整个注塑成型过程进行模拟CAE）分析，以便及时修改制件和模具设计同传统的模具设计相比，CAE技术无论在提高生产率、保证产品质量，还是在降低成本、减轻劳动强度等方面，都具有很大优越性。 全套完整版CAD图纸，联系153893706 Micromotor shell modeling and injection mold design and CAE analysis Author: Xiao Bin Class: 010J13 Director: Chang Chun Liu Xinyu Abstract: Injection mold is an important tooling for industry products ,it is the core of the modern manufacturing industry and in most countries injection mold design and manufacturing technology have become the keywords of measuring it’s production technology. Based on the present advanced 3D software UG , This paper realized the 3D modeling for the micromotor shell, analyzed the process and material of Micromotor shell, choosed the proper injection machine ,and roughcast reasonable injection mold design scheme .In the design process ，it used the configuration of two cavity in one plate and architecture of double-plate mould base. And through designing the parting line , running gate system, modeling parts , ejection stripping mechanism , cooling system , choosing adaptive standard mould base and standard parts ,it finished the whole mold design scheme for the Micromotor shell。 In addition ,for getting the qualitative plastic products, before the molding the CAE analysis was been done ,this assist on analyzing the potential problem , optimizing mold structure, technological parameter, so that the mold design could be modified in time. Results proved that CAE technology have great benefits in the field of improving the production efficiency, ensuring the product quality , reducing the cost and the intensity of labor.
