長筒注塑成型工藝與模具設(shè)計 摘 要本設(shè)計的題目是支承盤注塑成型工藝與模具設(shè)計,從圖紙上分析,該零件總體形狀為圓盤形。外形結(jié)構(gòu)比較簡單,但內(nèi),所以成型收縮后必留于型芯上。所以型腔應(yīng)設(shè)計在定模一側(cè),型芯設(shè)計在動模上,由于制件沒有側(cè)孔,所以不需側(cè)抽芯,采用直接抽芯即可。根據(jù)塑件的特點,模具型芯在動模部分。開模后,塑件應(yīng)收縮包緊型芯,而留在動模部分,其推出機構(gòu)采用推件板與頂管聯(lián)合推出的推件方式。該種脫模方式是在分型面處從殼體塑件的周邊推出。推出力大且均勻。對側(cè)壁脫模阻力較大的薄壁箱體或圓筒制品,推出后外觀上不留痕跡。對合導(dǎo)向機構(gòu)的功能三保證動定模部分能夠準(zhǔn)確對合,使分別加工在動模和定模上的成型表面在模具閉合后形成形狀和尺寸準(zhǔn)確的腔體,從而保證塑件形狀,壁厚和尺寸的準(zhǔn)確,該模具采用導(dǎo)柱對合導(dǎo)向機構(gòu)。導(dǎo)柱和型芯一起安裝在動模一側(cè),這樣在合模時可起保護作用。相信不久本模具投入市場一定能帶來很好的效益服務(wù)大眾,服務(wù)社會。關(guān)鍵詞: 塑料模具凸模推件板Suppers disc shaped crafts and die design molded plastic partsThis design topic is the pressed key components plastic note molds the design, analyzes from the blueprint, this components overall shape is a rectangle. Has 3 rectangular in the length direction the different shape holes, is easy to take shape. Looked from wall thickness that, the wall thickness most main point is the 1.5mm most narrow view is the 1.2mm wall thickness is even, is advantageous to components taking shape.According to models a characteristic, the mold core is moving the mold to be partial. After operates the mold, models to be supposed to contract male ,butRemains moves the mold to be partial, it promotes the organization to use pushes a board to promote pushes a way. This drawing of patterns way is peripheral models in a minute profile place from the shell to promote. Promotes the strength big also is even. To the sidewall drawing of patterns resistance big thin wall box body or the cylinder product, after promotes seemingly not the scar.The involution guidance organization function three guarantees moves decides the mold to be partial can the accurate involution, causes to process separately in moves the mold and decides on the mold to take shape the surface closed to form the shape and the size accurate cavity body after the mold, thus guaranteed models a shape, wall thickness and size accurate, this mold uses the guide pillar involution guidance organization. The guide pillar and the core installs together in moves a mold side, like this when gathers the mold may get up the protective function.Believed this mold invests the market certainly to be able soon to bring the very good benefit service populace, the service society.Critical word:plasticModelMaleEjector plate插圖清單圖 1 分型面的選擇……………………………………………………………………9圖 2 型腔的排列 ……………………………………………………………………10圖 3 分流道的結(jié)構(gòu) …………………………………………………………………12表格清單表 1 塑件的原材料分析………………………………………………………………4表 2 ABS 的注射成型的工藝參數(shù) …………………………………………………7表 3 工作尺寸的取值規(guī)定 …………………………………………………………16表 4 成型零件工作尺寸的計算 ……………………………………………………17
