摘要：在現(xiàn)代工業(yè)中，模具工業(yè)已成為制造業(yè)的基礎(chǔ)，這一觀點(diǎn)隨著全球制造業(yè)向我國(guó)轉(zhuǎn)移的過程中以被越來越多的有識(shí)之士所意識(shí)到。而在模具行業(yè)中塑料模又是其重中之重，種模具占模具行業(yè)總份額的50％以上，我國(guó)的塑料成型模具設(shè)計(jì)，制作技術(shù)比較晚，整體水平還比較低。目前單型腔、簡(jiǎn)單型腔的模具達(dá)70%以上，仍占主導(dǎo)地位。本論文介紹了洗衣機(jī)水管接頭的注射模設(shè)計(jì)過程。從型腔數(shù)量和布局的確定、注射機(jī)選擇、澆注系統(tǒng)設(shè)計(jì)、模板及其標(biāo)準(zhǔn)件的選用、脫模及抽芯機(jī)構(gòu)的設(shè)計(jì)、成型部件的設(shè)計(jì)等一一進(jìn)行了詳細(xì)的介紹。塑件有側(cè)孔，需要設(shè)計(jì)側(cè)向抽芯機(jī)構(gòu)，增加了模具的復(fù)雜程度。

Design of Injection Mol forUnion of Washing machine
Mechanical Design & Manufacturing and Automation  Xu Peixun  instructor  Pan Junsong
Abstract：In the modern industry, the die industry has become the
foundation of the manufacturing industry, this standpoint was along with the process that worldmanufacturing industry transfer to our country, which was been aware of by the private who more and more know. But in die profession plastics mold was heavy its heavy inside again,this kind of molding tool accounts for 50% of total quota in profession in molding tool above. In our country,because of the late of manufacture beginning the totalitily standard of mold design was very low about the plastics of taking shape. Nowaday,The proportion of odd casement, simple casement mold was over 70percent which was still dominant. This paper introduces the main process of the injection mould designing of the union,recounts the detail asthesefollowed:deciding of the number and the arrangement of the cavity, the detrusion components ,core-pulling outfit,and the feed system; selection of the machine for injection,the moulding boards and the
standardized parts .The plastics has one side hole,so needs to design a core-pulling part from the side. As a result ,it adds the complexity of the mould.
Keywords : injection mould;core-pulling;union.
