摘要
 模具是工業(yè)生產(chǎn)的基礎(chǔ)工藝裝備，是機械工業(yè)和高新技術(shù)產(chǎn)業(yè)的重要組成部分。注塑模具在模具領(lǐng)域中發(fā)展最快，應(yīng)用最廣泛，因此，研究注塑模具對了解塑料產(chǎn)品的生產(chǎn)過程和提高產(chǎn)品質(zhì)量有很大意義。本文的課題是游標(biāo)卡尺盒注塑模具設(shè)計，文中首先對注塑件進行結(jié)構(gòu)、工藝分析，然后通過測繪確定出了塑件的零件圖。在已知塑件材料為PP1340的情況下，確定了PP1340的收縮率、塑件的尺寸精度、塑件的表面質(zhì)量及成型的工藝參數(shù)，最后根據(jù)這些參數(shù)確定了注塑機的類型。在模具設(shè)計過程中，首先對分型面及型腔的數(shù)目進行確定，選擇模架后分別對澆注系統(tǒng)、澆口、導(dǎo)向定位機構(gòu)、滑塊、頂出系統(tǒng)、排氣系統(tǒng)、冷卻系統(tǒng)進行設(shè)計。模具的初步設(shè)計完成后，用Solid works軟件中的塑料顧問分別對澆口位置、塑料填充、冷卻質(zhì)量、注塑壓力等進行分析，來驗證模具設(shè)計的要否所合理，從而完成模具的設(shè)計。

　Abstract
 Mold is the basis for industrial production technology and equipment, and an important part of the machinery industry and high-tech industries. Injection mold is growing fastest and being most widely used in the mold areas. So studying the knowledge of injection mold is good to know more about the process of plastic products, and it also makes sense to improve the products quality. This article is about the injection mold design and this design is for a product of calipers box. Firstly, it produces the molding’s structure and technology, and then draw the detail drawing through mapping. In the case of knowing the mold material which is PP1340, the article makes sure of shrinkage, dimensional accuracy, surface quality and technological parameter of molding. At last, on the basis of those parameters choose a right injection molding machine. In the process of design, at first, it makes sure the numbers of molding sand and the location of parting surface. After choosing the mold base, start to design gating system、pouring gate、guide rail system、sliders、ejection system、exhaust system、cooling system. After finishing the first step of design, using plastic advisor of a part pro/engineer analyses gate location、molding filling、colling quality、injection pressure and so on to make sure the design is or not right. If everything is ok, then finish the design.
