摘要
塑料工業(yè)是當(dāng)今世界增長(zhǎng)最快的工業(yè)門類的其中之一，而注塑模具是其中發(fā)展比較快的種類，因此，研究注塑模具對(duì)了解塑料產(chǎn)品的生產(chǎn)過程和提高產(chǎn)品質(zhì)量有很大意義。
本論文介紹了注射成型的基本原理，特別是單分型面注射模具的結(jié)構(gòu)構(gòu)成與工作原理，對(duì)注塑產(chǎn)品提出了基本的要求，介紹了冷流道注射模具澆注系統(tǒng)和頂出系統(tǒng)的設(shè)計(jì)過程。設(shè)計(jì)成型零部件以及設(shè)計(jì)合理的推出機(jī)構(gòu)。并分析和闡述了模具型芯零件及各標(biāo)準(zhǔn)件的選材、熱處理工藝，塑件的結(jié)構(gòu)要素，塑件的尺寸公差和精度的選擇，塑件的體積和質(zhì)量的計(jì)算方法對(duì)設(shè)計(jì)進(jìn)行驗(yàn)證主要是對(duì)注射機(jī)的相關(guān)重要參數(shù)進(jìn)行驗(yàn)證包括模具閉合厚度、模具安裝尺寸等。在校驗(yàn)合格后，進(jìn)行成型零件加工工藝過程的制定，既要保證塑件的質(zhì)量，又要兼顧經(jīng)濟(jì)性。
通過本設(shè)計(jì)可以對(duì)注塑模具有一個(gè)更進(jìn)一步的認(rèn)識(shí)，了解模具結(jié)構(gòu)及工作原理。

Abstract
Plastic industry is one of the world's fastest growing industrial categories, and injection mould is one of the types of development faster, therefore, the research injection mold to understand the plastic product the production process and improve the quality of products has great significance.
This paper introduces the basic principle of injection molding, especially the single parting surface injection mould structure and working principle of the injection products put forward the basic requirements, this paper introduces the cold runner injection mould gating system and ejection system of the design process. And analyzes and expounds the mold core parts and the selection of materials, heat treatment process of the standard parts, plastic parts of structural elements, the choice of the size tolerance and precision of plastic parts, plastic parts quality and volume of the calculation method of the design verification is mainly related to the important parameters of the injection machine for validation including thickness, die die closed installation size, etc. After the calibration qualified for molding parts processing process, should not only guarantee the quality of plastic parts, and economy.
Through the design of injection mold has a further understanding, understand the die structure and working principle.
