摘要
塑料工業(yè)是當(dāng)今世界上增長(zhǎng)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(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。
本設(shè)計(jì)介紹了注塑成型的基本原理，特別是雙色注塑成型的結(jié)構(gòu)與工作原理，對(duì)注塑產(chǎn)品提出了基本的設(shè)計(jì)原則；詳細(xì)介紹了熱流道注射模具澆注系統(tǒng)、溫度調(diào)節(jié)系統(tǒng)和頂出系統(tǒng)的設(shè)計(jì)過程，并對(duì)模具強(qiáng)度要求做了說明；最后介紹了當(dāng)今世界上最為普及的三維CAD/CAM系統(tǒng)標(biāo)準(zhǔn)軟件PRO/ENGNEER的PROGRAM模塊，對(duì)螺桿和彈簧進(jìn)行了參數(shù)化設(shè)計(jì)。
通過本設(shè)計(jì)，可以對(duì)注塑模具有一個(gè)初步的認(rèn)識(shí)，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(duì)PROGRAM的學(xué)習(xí)，可以建立較簡(jiǎn)單零件的零件庫(kù)，從而有效的提高工作效率。

The Injection Model Design of Two-color Travel Cup
ABSTRACT
Plastics industry is one of the fastest growing industry categories in the world, and the injection mold is one of the types of rapid development. Therefore, it has great significance to understand the production process of injection mold plastic products and improve its quality when we research injection mold plastic products.
   The design introduces the basic principles of injection molding, in particular the two-color injection mold the structure and working principle. And it proposes the basic design principles of injection molding products. It gives details of the injection mold, pouring hot flow, temperature regulation system and to the top of design process. Besides, the mold have strength requirements done. Finally, it introduces the PROGRAM module of most popular 3D CAD / CAM system software standard PRO / ENGNEER in the world. And the Screw  and Spring sets parameters for the design.
    Through this design, we can have a preliminary understanding of the injection mold. At the same time, we note that the design of certain details of the understanding die structure and working principle. Through the study of PROGRAM, we can create a relatively simple components parts store, and effectively improve efficiency.
