塑料模具文獻(xiàn)綜述

1、塑料在國民經(jīng)濟(jì)的多個(gè)領(lǐng)域中得到廣泛的應(yīng)用 ,而它的產(chǎn)量按體積計(jì)算在世界上已超過了鋼鐵的產(chǎn)量。同時(shí) , 塑料模具是塑料成型加工中不可缺少的工具 , 在總的模具產(chǎn)量中所占的例逐年增加 , 在當(dāng)前已處于重要位置。在我國塑料模具的應(yīng)用在國民經(jīng)濟(jì)中的地位愈來愈重要。它的鋼材耗用量大 , 品種規(guī)格多 , 形狀復(fù)雜 , 表面粗糙度值要求低 , 制造難度大。因此 , 探討塑料模具的制造中的選用材料與熱處理問題 , 綜合分析其工作條件、失效、性能 , 合理選用材料與熱處理以及提高它的使用壽命 , 保證制件質(zhì)量 ,降低制造成本顯得非常重要。 1、塑料模 。

4、外文科技文獻(xiàn)譯文 裝 訂 線 1 塑料制品與塑料模具的發(fā)展趨勢 1、塑料產(chǎn)業(yè) 改革開放以來，塑料制品加工產(chǎn)業(yè)在我國以平均每年百分之十的速度迅速發(fā)展，與 平均增長點(diǎn)相比，要高出 3到 5個(gè)百分點(diǎn)?，F(xiàn)在，我國塑料制品已經(jīng)進(jìn)軍到了世界發(fā)達(dá)國家的水平，每年塑料產(chǎn)品的產(chǎn)量躍居世界第二，而且形成了完整的產(chǎn)業(yè)分類系統(tǒng)。 隨著塑料制品的應(yīng)用領(lǐng)域不斷擴(kuò)大，在未來 10年世界塑料制品的產(chǎn)量將在每年 3的的速度增加，在 2010年世界塑料產(chǎn)品的總?cè)萘繉⒏哌_(dá) 186萬噸。我國對(duì)塑料制品越來越大的需求將不斷，塑料產(chǎn)品的生產(chǎn)將在每年 10的的速度增加，據(jù)。

5、0前言機(jī)械工業(yè)是國民的裝備部，是為國民經(jīng)濟(jì)提供裝備和為人民生提供耐用消費(fèi)品的產(chǎn)業(yè)。機(jī)械工業(yè)的規(guī)模和技術(shù)水平是衡量國家經(jīng)濟(jì)實(shí)力和科學(xué)技術(shù)水平的要標(biāo)志。因此，世界各國都把發(fā)展機(jī)械工業(yè)作為發(fā)展本國經(jīng)濟(jì)的戰(zhàn)略重點(diǎn)之一1。生產(chǎn)水平及科學(xué)技術(shù)的不斷進(jìn)步與發(fā)展帶動(dòng)了整個(gè)機(jī)械工業(yè)的快速發(fā)展?，F(xiàn)代工業(yè)中，生產(chǎn)過程的機(jī)械化，自動(dòng)化已成為突出的主題。然而在機(jī)械工業(yè)中，加工、裝配等生產(chǎn)是不連續(xù)的。單靠人力將這些不連續(xù)的生產(chǎn)工序接起來，不僅費(fèi)時(shí)而且效率不高。同時(shí)人的勞動(dòng)強(qiáng)度非常大，有時(shí)還會(huì)出現(xiàn)失誤及傷害2。顯然，這嚴(yán)重影響。

7、1 塑料模具 的 編制和使用 M. 華聯(lián) 膏模具被廣泛用于鑄造 陶瓷行業(yè)所需的用具。除了 具有一定的優(yōu)勢，由于它們工作表面下穿在體內(nèi)的水分和電解質(zhì)的行動(dòng)，所以還具有 機(jī)械強(qiáng)度低，工作壽命短 的好處 。除此之外，在烘干機(jī)的溫度不能高于 65 度，高于此溫度石膏 將被銷毀。 陶瓷產(chǎn)業(yè)開始安裝時(shí)，尋找替代石膏的必要性增加為半自動(dòng)成型和干燥加劇干燥條件機(jī)。我們的工廠 1967 年開始搜索替代石膏 ，并為此組織了一個(gè)研究小組 ，其 中 包含以下工人： 利亞科夫，電訊管理局局長 吉尼亞州 I. 其他人。 該研究小組在 國家陶瓷研究的數(shù)據(jù)指導(dǎo)研究。

13、射成型 射成型 注塑主要用于生產(chǎn)熱塑性塑料零件，也是最原始的方法之一。目前注塑占所有塑料樹脂消費(fèi)量的 30%。典型的注塑成型產(chǎn)品“塑料杯、容器、外殼、工具手柄、旋鈕、電氣和通信組件 (如電話接收器 )、玩具、和水暖配件。 聚合物熔體由于其分子量具有很高的粘度；它們不能像金屬液在重力的條件下倒進(jìn)模 ,必須在高壓力下注入模具。因此 ,金屬鑄造的力學(xué)性能是由模具壁傳熱的速度決定，同時(shí)也決定了在最終鑄件的晶粒尺寸和晶粒取向 , 高壓注射成型過程中熔體的注射剪切力產(chǎn)生的主要原因是材料最后的分子取向。力學(xué)性能影 響成品都是因。
