style="text-indent:25px">隨著塑料工業(yè)的飛速發(fā)展和通用與工程塑料在強(qiáng)度等方面的不斷提高，塑料制品的應(yīng)用范圍也在不斷擴(kuò)大，塑料產(chǎn)品的用量也正在上升，因此，塑料模具應(yīng)運(yùn)而生。塑料模具，是塑料加工工業(yè)中和塑料成型機(jī)配套，賦予塑料制品以完整構(gòu)型和精確尺寸的工具。由于塑料品種和加工方法繁多，塑料成型機(jī)和塑料制品的結(jié)構(gòu)又繁簡(jiǎn)不一，所以，塑料模具的種類(lèi)和結(jié)構(gòu)也是多種多樣的。塑料模具的主要性能要求塑料薄膜成型加工中，模具的質(zhì)量對(duì)產(chǎn)品質(zhì)量的保證作用是不言而喻的。不同類(lèi)型的塑料制品、不同產(chǎn)品的成型工藝，對(duì)模具的材料、性能、形狀都有不同的要求。</p><p style="text-indent:25px"> 塑料模具，是塑料加工工業(yè)中和塑料成型機(jī)配套，賦予塑料制品以完整構(gòu)型和精確尺寸的工具。按照成型方法的不同，可以劃分為不同的模具種類(lèi)。注塑模具主要是熱塑性塑料件產(chǎn)品生產(chǎn)中應(yīng)用較為普遍的一種成型模具，注塑模具對(duì)應(yīng)的加工設(shè)備是注塑成型機(jī)，塑料首先在注塑機(jī)底加熱料筒內(nèi)受熱熔融，然后在注塑機(jī)的螺桿或柱塞推動(dòng)下，經(jīng)注塑機(jī)噴嘴和模具的澆注系統(tǒng)進(jìn)入模具型腔，塑料冷卻硬化成型，脫模得到制品。其結(jié)構(gòu)通常由成型部件、澆注系統(tǒng)、導(dǎo)向部件、推出機(jī)構(gòu)、調(diào)溫系統(tǒng)、排氣系統(tǒng)、支撐部件等部分組成，制造采用塑料模具鋼。注塑成型加工方式通常只適用于熱塑料品的制品生產(chǎn)，用注塑成型工藝生產(chǎn)的塑料制品十分普遍，從生活日用品到各類(lèi)復(fù)雜的電器、汽車(chē)零部件等都是用注塑模具成型的，它是塑料制品生產(chǎn)中應(yīng)用較廣的一種加工方法。塑料模具一般須在150°C-200°C下進(jìn)行工作。</p><div

根據(jù)產(chǎn)品的大小和厚度，以及注塑機(jī)的射膠量，確定模穴數(shù)。血壓計(jì)透明面板為了流道平衡，一般開(kāi)一模兩穴，尺寸較小時(shí)，較多可以開(kāi)四穴，這和注塑機(jī)的較大射膠量沒(méi)有什么關(guān)系，主要是模穴超過(guò) 4 穴時(shí)，注塑機(jī)調(diào)機(jī)困難，不良率增加。 2. 分型面的選擇，制品形狀簡(jiǎn)單，分型面一般沿塑件邊緣選擇將塑件留在動(dòng)模。檢查塑件邊緣的脫模斜度，脫模斜度要足夠大，分型面處有無(wú)小 R 等。 3. 進(jìn)膠點(diǎn)的選擇很重要，注塑 PMMA 材料的模具，流道要彎曲成 S 型，流道末端并設(shè)計(jì)較長(zhǎng)的冷料穴，生產(chǎn) 時(shí)很容易調(diào)氣紋和熔膠痕。澆口選擇在塑件的大端，這樣塑膠容易充滿(mǎn)型腔，在兩個(gè)孔位合膠線較不明顯。PC 料的流道需要短而粗，這是兩種透明料模具設(shè)計(jì)的不同點(diǎn)。流道和進(jìn)膠口的設(shè)計(jì)，流道開(kāi)梯形，進(jìn)膠口開(kāi)扇形，流道要拋光得非常光亮。塑料模具用鋼要有良好的熱穩(wěn)定性。宿州塑料件模具</p><p
