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(diǎn)。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，難以避免成型缺點(diǎn)。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。(2)壓縮成型俗稱壓制成型，北京保麗龍模具廠，是**早成型塑件的方法之一。壓縮成型是將塑料直接加入到具有一定溫度的敞開的模具型腔內(nèi)，然后閉合模具，在熱與壓力作用下塑料熔融變成流動狀態(tài)。由于物理及化學(xué)作用，而使塑料硬化成為具有一定形狀和尺寸的常溫保持不變的塑件。壓縮成型主要是用于成型熱固性塑料，北京保麗龍模具廠，如酚醛模塑粉、脲醛與三聚氰胺甲醛模塑粉、玻璃纖維增強(qiáng)酚醛塑料、環(huán)氧樹脂、DAP樹脂、有機(jī)硅樹脂、聚酰亞胺等的模塑料，還可以成型加工不飽和聚酯料團(tuán)（DMC），北京保麗龍模具廠、片狀模塑料（SMC）、預(yù)制整體模塑料（BMC）等。一般情況下，常常按壓縮膜上、下模的配合結(jié)構(gòu)，將壓縮模分為溢料式、不溢料式、半溢料式三類。(3)擠塑成型是使處于粘流狀態(tài)的塑料，在高溫和一定的壓力下。北京保麗龍模具廠</p><div

style="text-indent:25px">熱流道模具：此類模具結(jié)構(gòu)與細(xì)水口大體相同，其比較大區(qū)別是流道處于一個或多個有恒溫的熱流道板及熱唧嘴里，無冷料脫模，流道及澆口直接在產(chǎn)品上，所以流道不需要脫模，此系統(tǒng)又稱為無水口系統(tǒng)，可節(jié)省原材料，適用于原材料較貴、制品要求較高的情況，設(shè)計(jì)及加工困難，模具成本高。熱流道系統(tǒng)，又稱熱澆道系統(tǒng)，主要由熱澆口套，熱澆道板，溫控電箱構(gòu)成。我們常見的熱流道系統(tǒng)有單點(diǎn)熱澆口和多點(diǎn)熱澆口二種形式。單點(diǎn)熱澆口是用單一熱澆口套直接把熔融塑料射入型腔，它適用單一腔單一澆口的塑料模具；多點(diǎn)熱澆口是通過熱澆道板把熔融料分枝到各分熱澆口套中再進(jìn)入到型腔，它適用于單腔多點(diǎn)入料或多腔模具。北京保麗龍模具廠</p><div

刀口模切割線間的間隙**小，沖孔模修整時的分布寬度也很小，這些都是要注意的。6、收縮和變形，塑料易收縮（如PE)，有些塑件易變形，無論如何預(yù)防，塑件在冷卻階段都會發(fā)生變形。在這種條件下，就要改變成型模具的外形來適應(yīng)塑件的幾何偏差。例如：盡管塑件壁保持平直，但其基準(zhǔn)中心已偏離10mm；可以抬高模具底座，以調(diào)整這種變形的收縮量。7、收縮量。在制造吸塑成型模具時一定要考慮到下列的收縮因素。①成型制品收縮。如果不能清楚地知道塑料的收縮率，則必須取樣或用相似形狀的模具通過試驗(yàn)來得到。注意：通過這種方法只能得到收縮率，不能得到變形尺寸。②中間介質(zhì)的不利影響造成的收縮，如陶瓷、硅橡膠等。③模具所用材料的收縮，如鑄造鋁時的收縮。模具模具設(shè)計(jì)按國家職業(yè)定義，模具設(shè)計(jì)是：從事企業(yè)模具的數(shù)字化設(shè)計(jì)，包括型腔模與冷沖模，在傳統(tǒng)模具設(shè)計(jì)的基礎(chǔ)上，充分應(yīng)用數(shù)字化設(shè)計(jì)工具，提高模具設(shè)計(jì)質(zhì)量，縮短模具設(shè)計(jì)周期的人員。模具概念沖壓模具整體構(gòu)造可分成二大部分：（1）共通部分。（2）依制品而變動的部分。共通部分可加以標(biāo)準(zhǔn)化或規(guī)格化，依制品而變動的部分是難以規(guī)格化。</p><p

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(shí)現(xiàn)物品外形的加工。素有“工業(yè)之母”的稱號。在外力作用下使坯料成為有特定形狀和尺寸的制件的工具。用于沖裁、模鍛、冷鐓、擠壓、粉末冶金件壓制、壓力鑄造，以及工程塑料、橡膠、陶瓷等制品的壓塑或注塑的成形加工中。模具具有特定的輪廓或內(nèi)腔形狀，應(yīng)用具有刃口的輪廓形狀可以使坯料按輪廓線形狀發(fā)生分離（沖裁）。應(yīng)用內(nèi)腔形狀可使坯料獲得相應(yīng)的立體形狀。模具一般包括動模和定模（或凸模和凹模）兩個部分，二者可分可合。分開時取出制件，合攏時使坯料注入模具型腔成形。模具是精密工具，形狀復(fù)雜，承受坯料的脹力，對結(jié)構(gòu)強(qiáng)度、剛度、表面硬度、表面粗糙度和加工精度都有較高要求，模具生產(chǎn)的發(fā)展水平是機(jī)械制造水平的重要標(biāo)志之一。模具種類很多根據(jù)加工對象和加工工藝可分為：①加工金屬的模具。②加工非金屬和粉末冶金的模具。包括塑料模(如雙色模具、壓塑模和擠塑模等)、橡膠模和粉末冶金模等。根據(jù)結(jié)構(gòu)特點(diǎn)。北京保麗龍模具廠</p><p
