style="text-indent:25px">模具，工業(yè)生產(chǎn)上用以注塑、吹塑、擠出、壓鑄或鍛壓成型、冶煉、沖壓等方法得到所需產(chǎn)品的各種模子和工具。簡而言之，模具是用來制作成型物品的工具，這種工具由各種零件構(gòu)成，不同的模具由不同的零件構(gòu)成。它主要通過所成型材料物理狀態(tài)的改變來實現(xiàn)物品外形的加工。素有“工業(yè)之母”的稱號。模具除其本身外，還需要模座、模架、模芯導(dǎo)致制件頂出裝置等，這些部件一般都制成通用型。模具企業(yè)需要做大做精，要根據(jù)市場需求，及技術(shù)、資金、設(shè)備等條件，確定產(chǎn)品定位和市場定位，這些做法尤其值得小型模具企業(yè)學(xué)習(xí)和借鑒，集中力量逐步形成自己的技術(shù)優(yōu)勢和產(chǎn)品優(yōu)勢。所以，我國模具企業(yè)必須積極努力借鑒國外這些先進(jìn)企業(yè)的經(jīng)驗，以便其未來更好的發(fā)展。</p><p style="text-indent:25px">導(dǎo)引銷單元(料條送料方向之定位)：（1）、導(dǎo)引銷單元：導(dǎo)引銷之主要作用是連續(xù)沖壓加工時得到正確的送料節(jié)距。沖壓模具用導(dǎo)引單元有間接型(導(dǎo)引銷單獨使用)及直接型（導(dǎo)引銷裝設(shè)于沖頭內(nèi)部）兩種形式。（2）、導(dǎo)引銷之組裝方式與沖孔沖頭有相同（裝設(shè)于沖頭固定板）。利用彈簧將其受制于沖頭固定板。（3）、導(dǎo)引銷另外裝設(shè)于壓料板之形式，由于要求導(dǎo)引銷突出于壓料板之量達(dá)到一定及防止模具上升時之容易帶上被加工材料，壓料板之剛性及導(dǎo)引形式有必要注意之。（4）、導(dǎo)引銷單元有直接型，其裝設(shè)于沖頭內(nèi)，主要用于外形沖切（下料加工）或引伸工程之切邊加工，其位置定位系利用制品之孔及引伸部內(nèi)徑?；匚讳N：由于模具必需旋轉(zhuǎn)的動作，所以必需將頂出板固定，在回位銷上加彈簧使頂出板保持穩(wěn)定。</p><div

style="text-indent:25px">注射成型：是先把塑料加入到注射機的加熱料筒內(nèi)，塑料受熱熔融，在注射機螺桿或柱塞的推動下，經(jīng)噴嘴和模具澆注系統(tǒng)進(jìn)入模具型腔，由于物理及化學(xué)作用而硬化定型成為注塑制品。注射成型由具有注射、保壓（冷卻）和塑件脫模過程所構(gòu)成循環(huán)周期，因而注射成型具有周期性的特點。熱塑性塑料注射成型的成型周期短、生產(chǎn)效率高，熔料對模具的磨損小，能大批量地成型形狀復(fù)雜、表面圖案與標(biāo)記清晰、尺寸精度高的塑件；但是對于壁厚變化大的塑件，難以避免成型缺陷。塑件各向異性也是質(zhì)量問題之一，應(yīng)采用一切可能措施，盡量減小。模具制造的好與壞是要有標(biāo)準(zhǔn)：銘牌應(yīng)固定在模板和基準(zhǔn)角附近的模座上。銘牌固定可靠，不易脫落。上海汽車外飾模具制造生產(chǎn)廠</p><p
