摘要
 本文主要介紹注射成型工藝及模具設(shè)計(jì)。制件材料為ABS，總體形狀為箱蓋型。模具采用一模二腔的結(jié)構(gòu)形式，由于分型面較明確,結(jié)構(gòu)也不難,并沒(méi)有什么特殊要求,僅用單分型面模架。 通過(guò)對(duì)塑件材料、質(zhì)量、體積的分析與計(jì)算，合理選用注塑機(jī)，并對(duì)各個(gè)參數(shù)進(jìn)行了校核，設(shè)計(jì)出一副合理，經(jīng)濟(jì)，適用的塑料注塑模具。
 采用模具成型的工藝代替?zhèn)鹘y(tǒng)的切削加工工藝，可以大大的提高生產(chǎn)效率，保證零件質(zhì)量，節(jié)約材料，降低成本，從而取得很高的經(jīng)濟(jì)效益。因此，模具成型方法在現(xiàn)代工業(yè)的主要、部門(mén)中得到了極其廣泛的應(yīng)用。它已成為工業(yè)進(jìn)行大批兩生產(chǎn)的重要技術(shù)手段，對(duì)于保證制品質(zhì)量，縮短試制周期，進(jìn)而爭(zhēng)先占領(lǐng)市場(chǎng)，以及產(chǎn)品的更新?lián)Q代和新產(chǎn)品的開(kāi)發(fā)都具有決定性的意義，明顯地成為技術(shù)經(jīng)濟(jì)和國(guó)民經(jīng)濟(jì)發(fā)的關(guān)鍵。

Injection molding technology and die design
 ABSTRACT
 This article focuses on injection molding and die design .the product of the materials for ABS, the overall shape to the lid. die die to adopt a second Chamber, because the structure of the parting and more specific, structures do not difficult, there is nothing special requirements, with only a single parting moldbase. through the plastic material, quality, volume, accuraey, equitablly temperat, and each parameter checking, design a reasonable economic for plastic injection molds.
  Using mould shaping instead of the traditional cutting processing will improve the producing efficiency geatly  guaranteed the quality of the spare part, save the material, and reduce the costs, through this , high economic benefit will be achieved. So,it is widely used in the main apartment of the modern industry. It has been the important technology in  modern multitudinous producing, It is essential to the updating of the products, and the exploiting the new products.
Keywords: ABS ;plastic; moulding process ;single parting.
