泡沫滅火器噴嘴的注塑模具設(shè)計(jì)及成型工藝-抽芯塑料注射模含8張CAD圖帶開題,泡沫滅火器,噴嘴,注塑,模具設(shè)計(jì),成型,工藝,塑料,注射,cad,開題 摘 要 本設(shè)計(jì)的題目是泡沫滅火器噴嘴，通過塑件的工藝分析、注塑模結(jié)構(gòu)設(shè)計(jì)及有關(guān)計(jì)算、模具閉合高的的確定、注塑機(jī)有關(guān)參數(shù)的校核等，該模具基本符合要求。 該塑件要求表面沒有毛刺、凹陷等缺陷，沒有其它特別要求，故注塑較易實(shí)現(xiàn)。根據(jù)塑件的成型要求及模腔的排列方式，選用潛伏式澆口比較合適，該模具型芯采用組合式結(jié)構(gòu)，有利于填充、排氣。 型芯主要是成形制件的內(nèi)表面，本模具把型芯固定在定模一側(cè)，這樣可以簡單模具的結(jié)構(gòu)?？紤]加工的難易程度和材料的價值利用、塑件的形狀和尺寸，并考慮到塑件的生產(chǎn)率，本模具采用一模二件的結(jié)構(gòu)形式；凹模主要成型塑件外表面，結(jié)構(gòu)較簡單，將型腔設(shè)計(jì)成組合式結(jié)構(gòu)，既保證塑件外觀與質(zhì)量，模具加工也比較方便。從塑件結(jié)構(gòu)上看，將型腔與斜滑塊設(shè)計(jì)在一起，組成一個抽芯機(jī)構(gòu)。 關(guān)鍵詞：一模二腔、組合式型腔、斜滑塊抽芯、 潛伏式澆口。 Take off to want The topic of this design is a knob to note the mold of part designs, the piece of part craft analysis, and the mold construction design and relevant calculation, the molding tool shuts to match high really settle, note the machine of the concerning parameter etc., that molding tool is basic to meet the request. The part's piece requests the surface has no the hair stabs, hollow etc. blemish, inner part cannot conduct electricity the miscellaneous quality, have no other special request, so note the part than realizes easily.According to an alignment for modeling request and moldings method, choose to sprinkle with the side comparison accommodation, design, consider the choice from the wall the thick 3 mms enters to anticipate, anticipate to flow to thin place from the thick place, and the molding tool's type adopts the sectional construction, benefitting to fill , row spirit. The convex mold is a difficult easy degree to take shape a the piece of system inside surfaces, consider to process primarily with the material of worth a make use of, a rate of production for of shape with size, combining in consideration of the piece of the part , this molding tool adoption is sectional to model a mold six pieces constructions form;The cave mold models the part an outward appearance primarily, construction than simple, design the cave mold sectional construction, since guarantee the part an external appearance and quantity, the molding tool processes too more convenient. Because design of ability limited, design inside exsit a lot of not enough places, still hope the teacher gives to advise with understand. Key word: A The mold two , inclined slippery pieces ,take out the and incubare ,the type to sprinkle.  目 錄 緒論 ……………………………………………………………………………… 1 第一章 模塑工藝規(guī)程的編制 …………………………………………………… 3 1.1 塑件的工藝分析………………………………………………………… 3 1.2 計(jì)算塑件的體積與質(zhì)量………………………………………………… 5 1.3 塑件注塑工藝參數(shù)的確定……………………………………………… 5 第二章 注塑模結(jié)構(gòu)設(shè)計(jì)…………………………………………………………… 7 2.1分型面的選擇……………………………………………………………… 7 2.2 確定塑件型腔的排列方式……………………………………………… 8 2.3 澆注系統(tǒng)………………………………………………………………… 9 2.4 導(dǎo)柱和導(dǎo)套的選擇……………………………………………………… 10 2.5 排氣系統(tǒng)的設(shè)計(jì)………………………………………………………… 12 2.6 抽芯機(jī)構(gòu)設(shè)計(jì)…………………………………………………………… 12 2.7 成型零件的結(jié)構(gòu)設(shè)計(jì)…………………………………………………… 13 第三章 模具設(shè)計(jì)的有關(guān)計(jì)算…………………………………………………… 14 3.1 型腔、型芯工作尺寸的計(jì)算…………………………………………… 14 3.2 腔側(cè)壁厚度、底板厚度計(jì)算…………………………………………… 14 第四章 模具加熱與冷卻系統(tǒng)的計(jì)算…………………………………………… 16 4.1 模具溫度調(diào)節(jié)系統(tǒng)……………………………………………………… 16 4.2 加熱與冷卻的選擇……………………………………………………… 16 4.3 冷卻系統(tǒng)的計(jì)算………………………………………………………… 16 第五章 模具閉合高度的確定…………………………………………………… 19 第六章 注塑機(jī)有關(guān)參數(shù)的校核………………………………………………… 20 第七章 繪制模具總裝圖和非標(biāo)準(zhǔn)件工作圖…………………………………… 21 第八章 注塑機(jī)主要零件加工工藝規(guī)程的編制………………………………… 22 第九章 模具裝配………………………………………………………………… 23 9.1 模具安裝………………………………………………………………… 23 9.2 試?！?23 設(shè)計(jì)總結(jié)…………………………………………………………………………… 27 致謝………………………………………………………………………………… 28 參考文獻(xiàn)…………………………………………………………………………… 29
