摘 要:塑料工業(yè)是世界發(fā)展最快的工業(yè)之一。日常生活中幾乎每天都使用塑料制品。這些產(chǎn)品的大部分可由注塑成型方法生產(chǎn)。眾所周知,注塑成型工藝是制作各種形狀的產(chǎn)品和以低成本制作復(fù)雜形狀產(chǎn)品的制作工藝。 本次的畢業(yè)設(shè)計(jì)的主要內(nèi)容是圓規(guī)盒子上殼的注塑模具設(shè)計(jì)。從塑料材料的性能分析,根據(jù)塑件的基本形狀和尺寸入手,合理選擇注射的成型方法。通過(guò)對(duì)塑件工藝性的分析和對(duì)模具生產(chǎn)條件及制造水平的掌握,制訂出成形工藝卡。在制定出成形工藝卡以后,開(kāi)始進(jìn)行模具的結(jié)構(gòu)設(shè)計(jì)。其中模具的結(jié)構(gòu)設(shè)計(jì)過(guò)程包括:型腔的數(shù)目和位置的確定,模具的總體結(jié)構(gòu)形式設(shè)計(jì),動(dòng)模及定模成形零件尺寸的確定,澆注系統(tǒng)形式及尺寸的確定,脫模方式的確定,調(diào)溫及排氣系統(tǒng)的確定,模架的選擇待以上各步驟完成以后,便開(kāi)始繪制模具的結(jié)構(gòu)草圖,根據(jù)具體尺寸校核注塑模具及注塑機(jī)的有關(guān)尺寸,并對(duì)工藝參數(shù)進(jìn)行核定和計(jì)算之后進(jìn)行初步的審查對(duì)所存在的問(wèn)題進(jìn)行確定和修正,然后繪制模具總裝配圖,按裝配圖繪制成型零件及所有需要加工的零件工作圖,同時(shí)考慮零件的加工工藝。 關(guān)鍵詞:圓規(guī)上殼;注塑模具;塑料;注射機(jī);UG
ABSTRACT:Plastic industry is one of the fastest growing industries in the world. Daily use plastic products almost every day in the life. Most of these products can be manufactured by injection molding method. As is well-known, plastic injection molding process is made of the shape of the product and the making craft of making complex shape product at low cost. This graduation design is the main content of the compasses box shell injection mold design. From the plastic material performance analysis, according to the basic shape and size of plastic parts, selection of injection molding method. Through the analysis of plastic parts manufacturability and grasp of the mold manufacturing conditions and manufacturing level, work out forming process card. After make a forming process card, begin the mould structure design. Die structure design process including: cavity the determination of the number and location of the overall structure of the mould form design, dynamic model and the determination of dimensioning parts mold forming, gating system and the determination of size, determine the way of parting, the determination of thermal control and exhaust system, the choice of the die set for all steps has been completed, and began to draw the structure of the mould sketch, depending on the size check relevant dimensions of injection mould and injection molding machine, and the process parameters of verification and calculation after preliminary review to identify the problems and correct, and then draw die general assembly drawing, according to the assembly drawing molding parts and all parts need machining work diagram, at the same time consider parts processing technology.
