style="text-indent:25px">真空吸塑成型模具的設(shè)計包括了批量大小、幾何形狀設(shè)計等內(nèi)容。1、批量的大小實驗用，模具產(chǎn)量小時，可采用木材或樹脂進(jìn)行制造。但是，如果實驗用模具是為了獲得制品有關(guān)收縮、尺寸穩(wěn)定性及循環(huán)時間等的數(shù)據(jù)時，應(yīng)該使用單型腔模具來實驗，且能保證其能在生產(chǎn)條件下運(yùn)用。模具一般用石膏、銅、鋁或鋁-鋼合金制造，比較少用到鋁-樹脂。2、幾何形狀設(shè)計，設(shè)計時，經(jīng)常要綜合考慮尺寸穩(wěn)定性及表面質(zhì)量。例如，北京車燈模具制造生產(chǎn)廠家，制品設(shè)計和尺寸穩(wěn)定性要求采用陰模（凹模），但是表面要求光澤度較高的制品卻要求使用陽模（凸模），這樣一來，塑件訂購方會綜合考慮到這兩點(diǎn)，北京車燈模具制造生產(chǎn)廠家，以使制品能在較佳條件下進(jìn)行生產(chǎn)，北京車燈模具制造生產(chǎn)廠家。經(jīng)驗證明，不符合實際加工條件的設(shè)計往往是失敗的。熱流道模具的優(yōu)點(diǎn)：可縮短成型周期。北京車燈模具制造生產(chǎn)廠家</p><div

style="text-indent:25px">模具的加工種類：1．粗加工：粗加工策略需要根據(jù)毛坯的類型和模具型面的情況而定。如果毛坯為鍛件或鋼件，那么粗加工較好先選用區(qū)域清理模型加工，將毛坯的大部分余量去除掉，得到均勻的毛坯余量，為后序加工提供方便。2．半精加工：半精加工的主要目的是保證精加工時余量均勻，較常用的方法是先算出殘留材料的邊界輪廓（參考刀具未加工區(qū)域的三維輪廓），然后選用較小的刀具來加工這些三維輪廓區(qū)域，而不用重新加工整個模型。3．局部精加工：局部精加工一般是指清角加工。清角加工應(yīng)采用多次加工或系列刀具從大到小的加工方法。4．精加工：在精加工中，除非模具型面高度變化比較大，否則較好選擇平行精加工。</p><p style="text-indent:25px">模具的維護(hù)保養(yǎng)：1、彈簧等彈性零件在使用過程中彈簧較易損壞，通常出現(xiàn)斷裂和變形現(xiàn)象。采取的辦法就是更換，在更換過程中一定要注意彈簧的規(guī)格和型號，彈簧的規(guī)格和型號通過顏色、外徑和長度三項來確認(rèn)，只有在三項都相同的情況下才可以更換。彈簧以進(jìn)口的質(zhì)量為佳。2、模具使用過程中沖頭易出現(xiàn)折斷、彎曲和啃壞的現(xiàn)象，沖套一般都是啃壞的。沖頭和沖套的損壞一般都用相同規(guī)格的零件進(jìn)行更換。沖頭的參數(shù)主要有工作部分尺寸、安裝部分尺寸、長度尺寸等。3、緊固零件，檢查緊固零件是否松動、損壞現(xiàn)象，采取的辦法是找相同規(guī)格的零件進(jìn)行更換。模具精確合理的加工可以確保模具在出產(chǎn)進(jìn)程的安穩(wěn)和延伸壽數(shù)。</p><div

style="text-indent:25px">模具的制造一般都要經(jīng)過鍛造、切削加工、熱處理等幾道工序。為保證模具的制造質(zhì)量，降低生產(chǎn)成本，其材料應(yīng)具有良好的可鍛性、切削加工性、淬硬性、淬透性及可磨削性；還應(yīng)具有小的氧化、脫碳敏感性和淬火變形開裂傾向。1．可鍛性:具有較低的熱鍛變形抗力，塑性好，鍛造溫度范圍寬，鍛裂冷裂及析出網(wǎng)狀碳化物傾向低。2．退火工藝性:球化退火溫度范圍寬，退火硬度低且波動范圍小，球化率高。3．切削加工性:切削用量大，刀具損耗低，加工表面粗糙度低。4．氧化、脫碳敏感性:高溫加熱時抗氧化懷能好，脫碳速度慢，對加熱介質(zhì)不敏感，產(chǎn)生麻點(diǎn)傾向小。5．淬硬性:淬火后具有均勻而高的表面硬度。6．淬透性:淬火后能獲得較深的淬硬層，采用緩和的淬火介質(zhì)就能淬硬。7．淬火變形開裂傾向:常規(guī)淬火體積變化小，形狀翹曲、畸變輕微，異常變形傾向低。常規(guī)淬火開裂敏感性低，對淬火溫度及工件形狀不敏感。8．可磨削性:砂輪相對損耗小，無燒傷極限磨削用量大，對砂輪質(zhì)量及冷卻條件不敏感，不易發(fā)生磨傷及磨削裂紋。北京車燈模具制造生產(chǎn)廠家</p></p><br
