)力”，德國(guó)則冠之為“加工工業(yè)中的帝王”，在歐洲其他一些發(fā)達(dá)國(guó)家模具被認(rèn)為“磁力工業(yè)”由此可見(jiàn)模具在各國(guó)國(guó)民經(jīng)濟(jì)中的重要地位1。新材料、新技術(shù)、新工藝的研制、開(kāi)發(fā)和應(yīng)用。隨著塑料成型技術(shù)的不斷發(fā)展，模具新材料、模具加工新技術(shù)和模具新工藝方面的開(kāi)發(fā)己成為當(dāng)前模具工業(yè)生產(chǎn)和科研的主要任務(wù)之一2。我國(guó)模具標(biāo)準(zhǔn)件水平和模具標(biāo)準(zhǔn)化程度仍較低，與國(guó)外差距甚大,在一定程度上制約著我國(guó)模具工業(yè)的發(fā)展，為提高模具質(zhì)量和降低模具制造成本,模具標(biāo)準(zhǔn)件的應(yīng)要大力推廣3。本課題應(yīng)用性強(qiáng)，涉及的知識(shí)面與知識(shí)點(diǎn)較多，如注塑成型、模具設(shè)計(jì)、三維造型、運(yùn)動(dòng)仿真以及二維三維軟件的應(yīng)用。通過(guò)本課題的設(shè)計(jì)，將會(huì)在下述基本能力上得到培養(yǎng)和鍛煉（1）塑料件制品涉及及成型工藝的選擇（2）一般塑料件制品成型模具的設(shè)計(jì)能力（3）塑料制品質(zhì)量分析及工藝改進(jìn)、塑料模具結(jié)構(gòu)改進(jìn)設(shè)計(jì)的能力（4）掌握模具設(shè)計(jì)常用的商業(yè)軟件及同實(shí)際設(shè)計(jì)的結(jié)合的能力（5）使自己在文檔組織與檢索方面的能力得到提高（6）掌握寫(xiě)論文的一般步驟及格式方法，同時(shí)提高自己的學(xué)習(xí)、思考、解決問(wèn)題的能力，因?yàn)樽⑺苣＞邔?duì)我來(lái)說(shuō)是一個(gè)新的領(lǐng)域。
