【正文】 在此次畢業(yè)設(shè)計(jì)中，老師教會(huì)了我很多學(xué)習(xí)的方法，提高了自己自主設(shè)計(jì)的能力，邊學(xué)邊設(shè)計(jì)的能力以及查閱各種資料解決實(shí)際問(wèn)題的能力，同時(shí)，在設(shè)計(jì)過(guò)程中經(jīng)常與其它同學(xué)一起進(jìn)行問(wèn)題的探討，培養(yǎng)了自己與人交流溝通和協(xié)助合作的能力。影響價(jià)格的因素模具從開(kāi)發(fā)設(shè)計(jì)到投入生產(chǎn)使要經(jīng)過(guò)多個(gè)環(huán)節(jié)，因此影響模具價(jià)格的因素可以從以下幾個(gè)方面考慮。設(shè)計(jì)中采用壓縮彈簧來(lái)實(shí)現(xiàn)滑塊的定位。—20176。模具的工作溫度在40℃（平均），用常溫20℃的水作冷卻介質(zhì)，其出口溫度為25℃。在高速成型過(guò)程中，高溫的塑料熔體，將這些氣體驅(qū)趕并壓縮至死角，形成多個(gè)高溫高壓的氣壓室。絕大多數(shù)導(dǎo)向機(jī)構(gòu)由導(dǎo)柱和導(dǎo)套組成，稱(chēng)之導(dǎo)柱導(dǎo)向機(jī)構(gòu)，此外也有錐面，銷(xiāo)等作定位導(dǎo)向的結(jié)構(gòu)。凸模是成型塑件內(nèi)表面的成型零件，通?？煞譃檎w式和組合式兩種類(lèi)型。分型面的選擇的一般原則:①選取塑件最大投影截面為分型面；②在開(kāi)模時(shí)盡量使塑件留在動(dòng)模內(nèi)；③應(yīng)有利于側(cè)面分型和抽芯；應(yīng)合理安排塑件在型腔中的方位；考慮和保證塑件的外觀不遭損壞；盡力保證塑件尺寸的精度要求；有利于排氣；盡量使模具加工方便。對(duì)于大型復(fù)雜的制件，～，～，～。此外澆口設(shè)計(jì)需遵循下述原則：盡量縮短流動(dòng)距離。正確設(shè)計(jì)澆注系統(tǒng)對(duì)獲得優(yōu)質(zhì)塑料產(chǎn)品和提高生產(chǎn)率極為重要。在同一螺紋型芯或螺紋型環(huán)上有前后兩種螺紋時(shí)，應(yīng)使兩端螺紋的旋向和螺距相同。目前，～，模腔表壁的表面粗糙度應(yīng)為塑件的1/2，～。ABS的耐候性是它的另一個(gè)優(yōu)點(diǎn)，一般ABS塑件的使用溫度范圍為40～100176。而生產(chǎn)統(tǒng)計(jì)法需要大量的實(shí)踐數(shù)據(jù)，對(duì)當(dāng)前仍未成熟的靜電凈化器產(chǎn)業(yè)來(lái)講，資料還很不充分。它的主要設(shè)計(jì)參數(shù)包括電暈形式、起暈電壓、凈化效率、收塵極面積和有效驅(qū)進(jìn)速度等。 影響空氣凈化效果的主要因素：從原理上講，以上談到的三種不同類(lèi)型的空氣凈化器，都對(duì)室內(nèi)空氣有一定凈化作用。于是人們開(kāi)始追求新的嘗試，嘗試著自己能夠與眾不同，能夠從自己擁有的個(gè)性產(chǎn)品中得到獨(dú)特的心理享受和精神愉悅。個(gè)性化設(shè)計(jì)的范圍也早已延伸到一切可以發(fā)揮其特長(zhǎng)的領(lǐng)域[2]。1課題意義加濕器（humidifier）是一種增加房間濕度的家用電器。而對(duì)于舊房，由于長(zhǎng)久的使用，異味、寵物臭味、煙味、等也困擾著眾多居民。這種狀況凸顯出我國(guó)家用加濕器市場(chǎng)雖發(fā)展了近20年，但目前仍存在著較大的消費(fèi)“瓶頸”。顧客需求的個(gè)性化發(fā)展是社會(huì)發(fā)展和進(jìn)步的標(biāo)志之一，工業(yè)產(chǎn)品對(duì)顧客個(gè)性需求的滿(mǎn)足程度受生產(chǎn)力發(fā)展水平的制約。通過(guò)本設(shè)計(jì)，使學(xué)生在學(xué)習(xí)機(jī)械與藝術(shù)學(xué)科的基礎(chǔ)上，運(yùn)用掌握的機(jī)械設(shè)計(jì)與制造、藝術(shù)基礎(chǔ)知識(shí)與技能、練習(xí)表達(dá)機(jī)械結(jié)構(gòu)，零部件及產(chǎn)品外觀效果的各種表現(xiàn)方法。又需要能有效過(guò)濾空氣中的有害物質(zhì)。對(duì)于蜂窩型電場(chǎng)，可以取小蜂窩的內(nèi)切圓半徑為管半徑。設(shè)計(jì)凈化器時(shí)應(yīng)滿(mǎn)足，即，即電場(chǎng)風(fēng)速不能太大，否則帶電粒子在被捕集前可能被氣流卷吸帶出電場(chǎng)。C之間，模溫在60176。此外，合理布局加強(qiáng)筋還可以改善充模流動(dòng)性，減少內(nèi)應(yīng)力，避免氣孔、縮孔和凹陷等缺陷。 鎖模力的校核注射成形時(shí)，高壓塑料熔體充滿(mǎn)型腔時(shí)，會(huì)產(chǎn)生使模具沿分型面分開(kāi)的脹模力，此脹模力等于塑件和澆注系統(tǒng)在分型面上的投影面積與型腔壓力之積。定位圈為標(biāo)準(zhǔn)件，其結(jié)構(gòu)和尺寸可查表。避免產(chǎn)生噴射和蠕動(dòng)。 冷料穴的設(shè)計(jì)冷料穴位于主流道正對(duì)面的動(dòng)模板上，或處于分流道模道末端，其作用是除去熔體流動(dòng)前鋒的“冷料”，防止冷料進(jìn)入型腔而影響塑件質(zhì)量。4）型腔的圓形排列所占的模板尺寸大，雖有利于澆注系統(tǒng)的平衡．但加工困難。（2）模具制造公差：實(shí)踐證明，模具制造公差可取塑件公差的，即 δ 2=（）Δ，而且按成型加工過(guò)程中的增減趨向取“+”、“”符號(hào)，型腔尺寸不斷增大，則取“+δ z”型芯尺寸不斷減小則取“δ z”，中心距尺寸取“177。導(dǎo)柱的長(zhǎng)度通常應(yīng)高于凸模端面6～8 mm，以免在導(dǎo)柱未導(dǎo)正時(shí)凸模先進(jìn)入型腔與其碰撞而損壞。合模再?lài)?yán)密，由于分型面的平面誤差的縫隙作為排氣通道是足夠的。能將活動(dòng)型芯抽出和復(fù)位的機(jī)構(gòu)稱(chēng)為抽芯機(jī)構(gòu)，側(cè)向分型和抽芯機(jī)構(gòu)按動(dòng)力來(lái)源可分為手動(dòng)、氣動(dòng)、液壓和機(jī)動(dòng)四種類(lèi)型。斜導(dǎo)柱與滑塊斜孔配合間隙一般為1mm。）設(shè)計(jì)中取a180。在此之前，對(duì)于模具的了解很少，只有幾次在工廠里實(shí)習(xí)的機(jī)會(huì)接觸過(guò)，并沒(méi)有系統(tǒng)的理論知識(shí)。s for 100 one 300 mins, fullautomatic medicine box packer dress box speed 50 200 boxes/ ms in. But, on the international, the advanced aluminium moulds rushing steeping cover packer cutting frequency be able to reach 600 mins. Fullautomatic medicine box packer dress box speed is able to reach 600 ~ 800 box/ mins. Not only working speed of domestic medicines and chemical reagents package machinery is slow. And, the partner has bigger noise.2) Is under the control of horizontal backward. Domestic medicines and chemical reagents package machinery controls low, automation of level difference mostly , the malfunction leads height. (Main package machinery finger box dress controls domestic medicines and chemical reagents with drinking wine holding machinery with) adopt PLC to do a scene mostly. But, advanced medicines and chemical reagents package machinery realizes supervisory control abroad mostly from puter system. Under the control of horizontal relatively backward. Great majority domestic medicines and chemical reagents package machinery automation sex is relatively poor. Adopt a single to produce a pattern first monly. The fullautomatic production line is few. Two is that fullautomation works cannot to achieve. Require that the manpower feeds in raw material. Hand movement enchases. If in a little paper box packer, Page, paper box all needs medicine board , specifications paper to move charging personally. And require speciallyassigned person to pay attention to if specifications, medicine board, paper box already finish using at any time. Happen to avoid bringing about machine racing or bringing about inplete specifications, medicine board, and medicine box phenomenon. Other, domestic medicines and chemical reagents package mechanic failure rates are higher. Control a ponent (if the relay, electromagnetic valve, contactor, breaker etc.) etc. are often easy to damage. Halt also to frequently occur the malfunction.3) Functions are unitary, expansion sex is bad. Medicines and chemical reagents package machinery is that the form designs that specifically for specially appointed package. The general specification range inner in regulation is adjustable. But, a lot of our country medicines and chemical reagents package machinery considers insufficiency when designing that. Be not that reforming going a step further sets apart sufficient space. Cause the machinery designing that to be able to only adapt to the form board in several kinds simplicities. Change not adapting to wrapping material or the form board dimension. Fit in with even. The package finished product mass giving birth to a child is neither nice.4) Considers deficiency synthetically. Resource does not fully utilize. Our country medicines and chemical reagents there exists the chaos phenomenon in package machinery design. A lot of machinery designs that the personnel drags to the electric motor moving the synchrony technology, the servo drive technology do not knows. The problem simple electrical equipment available is resolved uses plicated mechanism to e to e true but. Some though the control organ works to e having adopt the synchrony electric motor to wait for a device. But choose block of wood dingdang. The maximum having brought about resource not only wastes this condition. And make machinery function designing that low.5) Model is inflexible. Model seldom considering machinery time medicines and chemical reagents of our country package machinery design. Many machine molding that the manufacturer produces is not beautiful do not have model even. Give person feeling to rigid, to inflexible, not to have vigor. A few medicine box packers are middle. The nut all assembles screw on the machine outside board. But, the oil cup and flow nipple that a little lubrication uses also can be seen everywhere. Be stained fully with a greasy dirt easy to use machine everywhere time oiling. Impression is rough to person. No beautiful.Two, medicines and chemical reagents package machinery conceptual design contentPeople longterm study passes. Define conceptual design being: Have been ascertaining the mission
