摘要：注射模具是生產(chǎn)各種工業(yè)產(chǎn)品的重要工藝裝備，是現(xiàn)代生產(chǎn)制造行業(yè)的核心，在大多數(shù)國家，注射模具設(shè)計(jì)與制造技術(shù)已經(jīng)成為衡量一個(gè)國家生產(chǎn)制造技術(shù)先進(jìn)與否的關(guān)鍵。
本設(shè)計(jì)以目前最先進(jìn)的三維高端軟件UG為核心，實(shí)現(xiàn)對小電機(jī)外殼的三維造型。通過對電機(jī)外殼的工藝、材料分析，選用適當(dāng)?shù)淖⑸錂C(jī)，并擬定合理的注射成型工藝方案。在模具設(shè)計(jì)中，采用一模兩腔的布局，二板式的模架結(jié)構(gòu)。并通過對分型面、澆注系統(tǒng)、成型零部件、頂出脫模機(jī)構(gòu)、冷卻系統(tǒng)的設(shè)計(jì)，選用適合的標(biāo)準(zhǔn)模架及標(biāo)準(zhǔn)件，完成對電機(jī)外殼的一套完整的模具設(shè)計(jì)方案。
另外，為得到合格的塑件制品，在模具加工前，在計(jì)算機(jī)上對整個(gè)注塑成型過程進(jìn)行模擬（CAE）分析，幫助分析潛在的問題，優(yōu)化模具結(jié)構(gòu)、工藝參數(shù)，以便及時(shí)修改制件和模具設(shè)計(jì)。結(jié)果表明，同傳統(tǒng)的模具設(shè)計(jì)相比，CAE技術(shù)無論在提高生產(chǎn)率、保證產(chǎn)品質(zhì)量，還是在降低成本、減輕勞動強(qiáng)度等方面，都具有很大優(yōu)越性。

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.
Keywords: Injection Mold 3D Modeling CAE Analysis
