style="text-indent:25px">塑料配件在消費(fèi)產(chǎn)品設(shè)計(jì)中很常見(jiàn)，這是有充分理由的。（塑料配件）高度耐用，并且有無(wú)限的顏色可以選擇，當(dāng)然，大批量生產(chǎn)時(shí)，價(jià)格低廉。對(duì)于URB-E的工程和設(shè)計(jì)團(tuán)隊(duì)來(lái)說(shuō)，將塑料部件用于擋泥板和電池輪轂以增加其生產(chǎn)并不容易。這是否意味著您必須成為塑料配件**才能在SOLIDWORKS中設(shè)計(jì)一個(gè)合格的產(chǎn)品呢？在注模塑料部件上繪制筋是不可避免的設(shè)計(jì)特征，正確的拔模角度將確保零件在推出時(shí)容易滑出模具，并避免對(duì)塑料配件和模具造成任何昂貴的損壞。使用SOLIDWORKS，可以使用拔模分析工具輕松識(shí)別3D模型中需要拔模角度的面。URB-E的電池盒蓋在設(shè)計(jì)中，拔模是一個(gè)非常重要的步驟，該部分剛開(kāi)始是為形狀和功能而設(shè)計(jì)的，并且采用3D打印技術(shù)，現(xiàn)在是在剛開(kāi)始的設(shè)計(jì)階段就需要考慮具有拔模角度的筋。除了確保零件彈出沒(méi)有任何問(wèn)題之外，正負(fù)色碼將有助于確定分模線和鎖模線的位置。吉林耐寒塑料配件供應(yīng)廠家塑料配件成型后塑料產(chǎn)品緊緊抱住模具型芯或型腔中凸出部位，給取出產(chǎn)品帶來(lái)困難。</p><div

根據(jù)產(chǎn)品大小，確定零件主體壁厚。零件本身的強(qiáng)度，由壁厚塑料配件、結(jié)構(gòu)形式（平板形狀的的塑料配件強(qiáng)度較差）、加強(qiáng)筋與加強(qiáng)骨共同決定。在決定零件的單個(gè)強(qiáng)度的同時(shí)，須確定零件之間的連接強(qiáng)度，改變連接強(qiáng)度的方法有，加螺釘柱，加止口，加扣位，加上下頂住的加強(qiáng)骨。塑料配件的脫模斜度由材料，表面飾紋狀態(tài)，零件透明與否決定。硬質(zhì)塑料比軟質(zhì)塑料的脫模斜度大，零件越高，孔越深，斜度越小。塑料配件一般精度不高，在實(shí)際使用中，我們主要檢驗(yàn)裝配尺寸，在平面圖上主要標(biāo)注總體尺寸，裝配尺寸，及其它需要控制的尺寸。 </p> <p> <br /> </p><p> 在設(shè)計(jì)塑膠件產(chǎn)品時(shí)，無(wú)論外觀還是里面的結(jié)構(gòu)都要有脫模斜度。 </p> <p> 脫模斜度與產(chǎn)品外觀、材料、產(chǎn)品外形尺寸、產(chǎn)品功能相關(guān)。n 塑料產(chǎn)品的凸起或加強(qiáng)筋，單邊應(yīng)有4°?5°的脫模斜度。 </p> <p> 厚壁產(chǎn)品會(huì)因壁厚使成型收縮增大，故斜度應(yīng)放大。若斜度不妨礙產(chǎn)品的使用，則可將斜度值取大些。 </p> <p> 熱固性塑料較熱塑性塑料收縮小些，脫模斜度也相應(yīng)小些。復(fù)雜及不規(guī)則形狀的產(chǎn)品其斜度應(yīng)大些。 </p> <p> 內(nèi)表面斜度比外表面斜度應(yīng)大些。 </p> <p> 不通孔深度小于10mm，外形高度不大于 20mm時(shí)，允許不設(shè)計(jì)斜度。 </p> <p> 有時(shí)根據(jù)產(chǎn)品預(yù)留的位置來(lái)確定脫模斜度。若為了在開(kāi)模后讓產(chǎn)品留在凸模上，則可有意將凸模斜度減小，而將凹模斜度放大，反之亦然。在滿足塑料產(chǎn)品尺寸公差要求的前提下，脫模斜度可以取大些。 </p> <p> <br /> 由于塑料件的結(jié)構(gòu)和用料的不同，采用的脫模方式也有所不同。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="吉林耐寒塑料配件供應(yīng)廠家,塑料配件"

現(xiàn)在，塑料外殼的應(yīng)用已經(jīng)普遍起來(lái)了，生活中，我們都是很常見(jiàn)的，比如：電器殼，還有我們平常用的洗臉盆，都是屬于塑料的，但是在塑料加工的時(shí)候，顏色不穩(wěn)定是常見(jiàn)的問(wèn)題。 </p> <p> 1、先要檢查的是注塑機(jī)的溫度，顏色不穩(wěn)定，跟注塑機(jī)的溫度時(shí)高時(shí)低是有關(guān)聯(lián)的，所以，在塑料外殼加工時(shí)，一定要優(yōu)先檢查。 </p> <p> 2、有的時(shí)候背壓調(diào)的過(guò)大，生產(chǎn)周期的不穩(wěn)定，生產(chǎn)周期不穩(wěn)定，時(shí)開(kāi)時(shí)停，都會(huì)使顏色發(fā)生變化的。 </p> <p> 3、混料工沒(méi)有按照混料工藝來(lái)混合色粉和原料，比如時(shí)間不足、加料方式或者是加料的順序不一致導(dǎo)致色分不均勻，這也是造成顏色不穩(wěn)定的原因之一，所以，在加工塑料外殼時(shí)也是要重點(diǎn)檢查的。 </p> <p> 4、由于原料的濕度太大，里面的粘度還沒(méi)有擴(kuò)散，較后就會(huì)造成塑料加工顏色的不穩(wěn)定。 </p>
