摘    要
塑料工業(yè)是當(dāng)今世界上增長最快的工業(yè)門類之一，而注塑模具是其中發(fā)展較快的種類，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。
本設(shè)計(jì)的目的是設(shè)計(jì)一個(gè)注塑模具，這個(gè)模具用來生產(chǎn)四分光器外殼的一個(gè)部件。在開始部分介紹了四分光器的工作原理，而四分光器的外殼是多個(gè)塑料注件裝配而成的，所以本設(shè)計(jì)的重點(diǎn)是注塑模具的設(shè)計(jì)，此模具可以注出分光器外殼的一個(gè)塑件。這個(gè)塑件有多個(gè)側(cè)孔，所以需要多個(gè)側(cè)抽芯，這也是難點(diǎn)部分。
模具設(shè)計(jì)的開始，通過對塑件的尺寸分析，初步選擇注射機(jī)和模架，然后根據(jù)所選的模架開始畫總裝圖，在圖中逐步加上所需零部件，這個(gè)過程中需要計(jì)算和確定尺寸，還可能要反復(fù)修改。我在設(shè)計(jì)時(shí)換了兩套模架和三種注射機(jī)才選到較合理的配備形式。到總裝圖基本完成時(shí)，我開始用PRO/E畫各個(gè)零件圖，在這個(gè)過程中可能發(fā)現(xiàn)之前定的尺寸有的不合理，所以又要反回去計(jì)算定尺寸，還要查標(biāo)準(zhǔn)進(jìn)行圓整。
通過本設(shè)計(jì)，可以對注塑模具有一個(gè)初步的認(rèn)識，注意到設(shè)計(jì)中的某些細(xì)節(jié)問題，了解模具結(jié)構(gòu)及工作原理。通過對PRO/E的學(xué)習(xí)，可以建立一般復(fù)雜的零件實(shí)體，可以建立立體裝配圖。

Abstract
Plastics industry is one of the world's fastest growing industry categories, and the injection mold is one of the types of rapid development, and therefore the study of plastic injection molds for understanding the production process and improve the quality of products have great significance.
The purpose of this design is to design a plastic injection mold, the mold is used to produce a quarter of an optical parts casing. in the beginning , a QV4 introduced of the working principle of optical devices, optical devices and a quarter more than the shell is assembled from pieces of plastic injection, so this is designed to focus on the design of injection mold, the mold can be injected by the Shell a plastic parts. There are a number of plastic parts of the side hole, so it is necessary to draw a number of side cores, which is difficult in part.
In the beginning of  design, plastic parts of the size analysis, the initial choice of injection molding machine and mold, and then die carrier in accordance with the beginning of the selected painting assembly diagram, and gradually add in the necessary map components, this process needs to be calculated and determine the size, also may have to repeatedly modify. I changed the design of two sets of injection mold machines and three before the election with a more reasonable form. To map the basic assembly is complete, I began to use PRO / E painting various parts diagram, in the process may be found prior to setting the size of some irrational and therefore will be to calculate the anti-back size, but also check roundness standards.
Through the design, I known an initial of the injection mold, the design notes that some of the details to understand the structure and working principle of mold. Through the PRO / E Learning, I can draw some of the entity complex parts, I can fix then to a three-dimensional assembly.

Key words: injection mold; surface; injection machine; plastic products; Splitter
