摘  要
 注射成型是塑料成型的一種重要方法，它主要適用于熱塑性塑料的成型，可以一次成型形狀復(fù)雜的精密塑件。本課題就是將東安車中葉片框扣板作為設(shè)計(jì)模型，將注射模具的相關(guān)知識(shí)作為依據(jù)，闡述塑料注射模具的設(shè)計(jì)過程。
 模具在國民經(jīng)濟(jì)中所占據(jù)的地位日益顯著，可以說人類的衣、食、住、行，沒有哪一方面離得開模具。模具是機(jī)械、汽車、電子、通訊、家電等工業(yè)產(chǎn)品的基礎(chǔ)工藝裝備，屬于高新技術(shù)產(chǎn)品。作為基礎(chǔ)工業(yè)，模具的質(zhì)量、精度、壽命對(duì)其他工業(yè)的發(fā)展起著十分重要的作用，在國際上稱為“工業(yè)之母”。隨著我國國民經(jīng)濟(jì)的迅速發(fā)展，作為工業(yè)品基礎(chǔ)的模具工業(yè)，也得到了蓬勃發(fā)展，已成為國民經(jīng)濟(jì)建設(shè)中的重要產(chǎn)業(yè)。模具工業(yè)不但在國民經(jīng)濟(jì)中占據(jù)重要地位，在世界市場上也是獨(dú)樹一幟。
 模具按制造的產(chǎn)品分類，可以分為塑料模具（又分為注塑模具、鑄壓模具和吹塑模具）、沖壓模具、鑄造模具、橡膠模具和玻璃模具等。其中，尤以注塑模具和沖壓模具用途廣、技術(shù)成熟、占據(jù)的比重大。
 
關(guān)鍵詞：塑料特性、型芯和型腔結(jié)構(gòu)、模具結(jié)構(gòu)、標(biāo)準(zhǔn)模架

Abstract
 Domestic market to plastic mold injection mold greatest demand, which focused on the development of engineering plastics die. Plastic injection molding molding is an important method, which is primarily applicable to thermoplastic plastic molding, Molding can be a complex shape of precision plastic parts..  Mold in the national economy in the occupied status is increasingly significant, it can be said of human clothing, food, housing, transportation, no one can leave mold. Mold are high-tech products in the machinery, automotive, electronics, telecommunications, household appliances, and other industrial products based process equipment. As basic industries, the quality of molds, precision, life on other industrial development plays an important role in the international community as "the mother of industry." With the rapid development of China's national economy, as the basis of industrial tooling industry, has also been vigorous development of the national economy has become an important industry in the building. Tooling industry in the national economy not only occupy an important position in the world market is also unique.
 Mold by manufacturing the product category, can be divided into plastic molds (also divided into injection mold, pressure mold casting and blow mold), stamping molds, mold casting, rubber molds and mold, and other glass. Among them, especially injection molds and stamping mold-use, technological maturity, which hold the majority.
 This text take the frame of blade buckled of Chery's Auto's injection mold   for example. discussed in detail the process of plastic, ABS plastics processing parameters, cavity and core structural forms Mold Design, mode-choice principles, and strive to do with reality and theory reflect the advanced level both at home and abroad.    
Key words: plastic characteristics of core and cavity structure, mold structure, the standard mold base
