摘 要
模具是進(jìn)行產(chǎn)品制造的一種全新工具，隨著塑料工業(yè)的發(fā)展，塑料注塑模已經(jīng)成為塑料制品的主要成型手段之一。它有著簡(jiǎn)單、快捷的優(yōu)點(diǎn)，特別是隨著汽車(chē)工業(yè)的發(fā)展，模具行業(yè)面臨著一個(gè)全新的發(fā)展機(jī)遇。
本文主要介紹了組合儀表罩單型腔注塑模的設(shè)計(jì)過(guò)程。首先分析了塑件外形、結(jié)構(gòu)及所用的塑料性能，選擇注射機(jī)并對(duì)其中的部分參數(shù)進(jìn)行了校核，初步確定了設(shè)計(jì)方案。接著是注塑模的總體結(jié)構(gòu)設(shè)計(jì)，包括了澆注系統(tǒng)設(shè)計(jì)、成型部分及其零部件設(shè)計(jì)、排溢與引氣系統(tǒng)設(shè)計(jì)、溫度調(diào)節(jié)系統(tǒng)中冷卻系統(tǒng)設(shè)計(jì)、脫模機(jī)構(gòu)設(shè)計(jì)。本文著重進(jìn)行了脫模機(jī)構(gòu)設(shè)計(jì)，它完成成型后的塑件與模具松動(dòng)、分離，主要是側(cè)向抽芯機(jī)構(gòu)及頂出機(jī)構(gòu)設(shè)計(jì)。
論文有詳細(xì)的計(jì)算過(guò)程，圖文并茂，使讀者更加容易明白設(shè)計(jì)過(guò)程。最后闡述了完成此次設(shè)計(jì)后的心得體分，并對(duì)以后的模具設(shè)計(jì)思路提出了自己的見(jiàn)解和看法。

Abstract
The mould is one kind of new tools to manufacture the products，with the development of the plastic, the injection mould has been become one of main methods for plastics products formation. With the advantage of simple and quick, especially with the development of automobile industry, the mould industry is facing a new development opportunity.
The design process of the automobile combination instrument cover single-cavity injection mould is mainly introduced in this paper. The shape, structure of the plastic part and the performance of using plastic are firstly analyzed, and the injection machine is selected with some of its parameters being checking, determining the design proposal. Then the overall structure of the injection mould is designed, including the pouring system design, the formation part and its components design, the overflow and bleed system design, the cooling system of temperature adjusted system design, demould mechanism design. The demould mechanism design is emphatically introduced in the paper, which accomplish the plastic part isolating from the mould, the side-extracting core mechanism design and the ejecting mechanism design being two emphasizes.
There are detailed computation process and rich illustrations in this paper , which make the reader understand the design easily. The experiences are expounded at the end of the paper, at the same time personnel understanding is suggested for the future mould design
Keywords: Injection mould Pouring system Cooling system Side-extracting core mechanism Ejecting mechanism
