摘 要:利用模具成型零件的方法，就是一種少切削、無(wú)切削、多工序重合的生產(chǎn)方法，采用模具成型的工藝代替?zhèn)鹘y(tǒng)的切削加工工藝，可以提高生產(chǎn)率、保證零件質(zhì)量、節(jié)約材料、降低生產(chǎn)成本，從而取得很高的的經(jīng)濟(jì)效益，因此，模具成型方法在先代工業(yè)中，如機(jī)械、電子、輕工、交通和國(guó)防工業(yè)中得到了及廣泛的應(yīng)用。 ?。?）通過(guò)對(duì)飯盒的觀察分析，從塑件的形狀，結(jié)構(gòu)初步畫(huà)出三維圖形，然后對(duì)塑件進(jìn)行質(zhì)量屬性分析，尺寸精度的分析，確定塑件的材料，同時(shí)對(duì)塑件的成型工藝，性能數(shù)據(jù)加以分析。 ?。?）通過(guò)對(duì)塑件體積、質(zhì)量的計(jì)算，確定注射機(jī)型號(hào)并對(duì)注射機(jī)參數(shù)進(jìn)行校核；通過(guò)確定型腔數(shù)目、型腔分布、型腔分型面設(shè)計(jì)確定塑件在模具中的位置。 ?。?）對(duì)模具的澆注系統(tǒng)、模具成型部分的結(jié)構(gòu)、頂出系統(tǒng)、冷卻系統(tǒng)、注塑機(jī)進(jìn)行選擇以及對(duì)有關(guān)參數(shù)進(jìn)行校核。 （3）用CAD和UG繪圖軟件繪制二維零件圖、裝配圖、以及三維實(shí)體。 關(guān)鍵字：注塑模；飯盒；CAD；UG
ABSTRACT:By using the method of molding parts, is a kind of of coincidence with less cutting and no cutting, production methods, adopt the molding process instead of traditional machining process, can improve productivity, ensure the quality of parts, save material, reduce the production cost, thus to achieve a high economic benefit, therefore, molding method in the modernize the industry, such as machinery, electronics, light industry, transportation and national defense industry and widely used. (1) through the observation of the lunch box analysis, from the shape of the plastic parts, preliminary draw the 3 d graphics, structure and quality of the molded parts attribute analysis, dimension accuracy analysis, determine the plastic material, the molding process of plastic parts at the same time, analyze performance data. (2) based on the volume and quality of plastic parts, injection machine number and check for injection machine parameter; By determining number of cavity, cavity, cavity parting surface design to determine the positions of the plastic parts in the mold. (3) the mould gating system, molding part of the structure, the ejector system, cooling system, choose injection molding machine and related parameters for checking. (4) using CAD and UG drawing software rendering 2 d part drawing, assembly drawing and 3 d entity. Key words: injection molding; Lunch box; CAD; UG |
