摘要
　 隨著塑料工業(yè)的發(fā)展，塑料注射模已經(jīng)成為制造塑料制品的主要手段之一。本文主要介紹了塑料注射模設(shè)計(jì)的方法及過程。首先，介紹了塑料注射模設(shè)計(jì)與制造在社會(huì)發(fā)展過程中所處的地位和作用，并對(duì)塑料制品（汽車煙灰缸蓋）的結(jié)構(gòu)進(jìn)行了分析和適當(dāng)?shù)男薷?，然后介紹了塑料注射模具的具體設(shè)計(jì)過程。具體設(shè)計(jì)內(nèi)容包括：注射機(jī)型號(hào)的選擇、分型面的確定、抽芯機(jī)構(gòu)及頂出機(jī)構(gòu)設(shè)計(jì)、成型零部件的設(shè)計(jì)、澆注系統(tǒng)、冷卻系統(tǒng)和復(fù)位系統(tǒng)的設(shè)計(jì)，此外，還對(duì)塑料注射模其他零部件進(jìn)行了簡(jiǎn)單的設(shè)計(jì)。最后闡述了完成此次設(shè)計(jì)之后的心得，并對(duì)以后的模具設(shè)計(jì)思路提出了自己的見解和看法。

Abstract
With the development of the plastic industry, the plastic injecting mold has already become one of the mainly ways of making the plastic ware. This paper mainly introduces the method and the process of the injecting mold designing. First, It has introduced the position and function in the developing society of the plastic injecting mold’s making and designing, and analysied the structure of the plastic product ,and also modified some parts of the structure .Next, this paper introduce the concrete process of the plastic mold’s designing. according to the actual designing plastic, carried on the analysis and modifications of the plastic product’s structure craft, the next chapter introduced the concrete design process of the plastic injecting mold.The injecting machine was chosen according to the product’s weight,the face was chosen according to the structure of the plastics and model the type of cent of the craft、taking out the organization of core and the outing organizations、noting system、cooling system and resetting the system to carry on the detailed design towards modeling zero parts and sprinkling at the same time。In addition, return to design of plastics injected other zero parts of mold to carry on the simple design, the insight was elaborating in the end of the paper, and the later designing way of the injecting mold was put forward my views and viewpoints.
Key words: injecting mold design mold plastic
