摘  要
近年來，我國塑料模具水平已有較大提高。大型塑料模具已能生產(chǎn)單套重量達(dá)50t以上的注塑模，精密塑料模的精度已可達(dá)到3μm，制件精度為0.5μm的小模數(shù)齒輪模具及達(dá)到高光學(xué)要求的車燈模具等也已能生產(chǎn)，多腔塑料模已能生產(chǎn)一模7800腔的塑封模，高速模具方面已能生產(chǎn) 4m/min以上擠出速度的高速塑料異型材擠出模及主型材雙腔共擠、雙色共擠、軟硬共擠、后共擠、再生料共擠出和低發(fā)泡鋼塑共擠等各種模具。在生產(chǎn)手段上，模具企業(yè)設(shè)備數(shù)控化率已有較大提高，CAD/CAE/CAM技術(shù)的應(yīng)用面已大為擴大，高速加工及 RP/RT 等先進(jìn)技術(shù)的采用已越來越多。模具標(biāo)準(zhǔn)件使用覆蓋率及模具商品化率都已有較大幅度的提高，熱流道模具的比例也有較大提高。三資企業(yè)蓬勃發(fā)展進(jìn)一步促進(jìn)了塑料模具設(shè)計制造水平及企業(yè)管理水平的提高。
現(xiàn)代模具技術(shù)的發(fā)展，在很大程度上依賴于模具標(biāo)準(zhǔn)化、優(yōu)質(zhì)模具材料的研究、先進(jìn)的設(shè)計與制造技術(shù)、專用的機床設(shè)備，更重要的是生產(chǎn)技術(shù)的管理等。21世紀(jì)模具行業(yè)的基本特征是高度集成化、智能化、柔性化和網(wǎng)絡(luò)化。追求的目標(biāo)是提高產(chǎn)品的質(zhì)量及生產(chǎn)效率，縮短設(shè)計及制造周期，降低生產(chǎn)成本，最大限度地提高模具行業(yè)的應(yīng)變能力，滿足用戶需要。可見，未來我國模具工業(yè)和技術(shù)的主要發(fā)展方向?qū)⑹牵?br /> 1.大力普及、廣泛應(yīng)用CAD/CAE/CAM技術(shù)，逐步走向集成化。現(xiàn)代模具設(shè)計制造不僅應(yīng)強調(diào)信息的集成，更應(yīng)該強調(diào)技術(shù)、人和管理的集成。
2.提高大型、精密、復(fù)雜與長壽命模具的設(shè)計與制造技術(shù)，逐步減少模具的進(jìn)口量，增加模具的出口量。
3.在塑料注射成型模具中，積極應(yīng)用熱流道，推廣氣輔或水輔注射成型，以及高壓注射成型技術(shù)，滿足產(chǎn)品的成型需要。
4.提高模具標(biāo)準(zhǔn)化水平和模具標(biāo)準(zhǔn)件的使用率。模具標(biāo)準(zhǔn)件是模具基礎(chǔ)，其大量應(yīng)用可縮短模具設(shè)計制造周期，同時也顯著提高模具的制造精度和使用性能，大大地提高模具質(zhì)量。我國模具商品化、標(biāo)準(zhǔn)化率均低于30%，而先進(jìn)國家均高于70%，每年我們要從國外進(jìn)口相當(dāng)數(shù)量的模具標(biāo)準(zhǔn)件，其費用約占年模具進(jìn)口額的3%～8%。
5.發(fā)展快速制造成型和快速制造模具，即快速成型制造技術(shù)，迅速制造出產(chǎn)品的原型與模具，降低成本推向市場。
6.積極研究與開發(fā)模具的拋光技術(shù)、設(shè)備與材料，滿足特殊產(chǎn)品的需要。
7.推廣應(yīng)用高速銑削、超精度加工和復(fù)雜加工技術(shù)與工藝，滿足模具制造的需要。
8.開發(fā)優(yōu)質(zhì)模具材料和先進(jìn)的表面處理技術(shù)，提高模具的可靠性。
9.研究和應(yīng)用模具的高速測量技術(shù)、逆向工程與并行工程，最大限度地提高模具的開發(fā)效率與成功率。
10.開發(fā)新的成型工藝與模具，以滿足未來的多學(xué)科多功能綜合產(chǎn)品開發(fā)設(shè)計技術(shù)。
根據(jù)塑料制品的要求，了解塑件的用途，分析塑件的工藝性、尺寸精度等技術(shù)要求，選擇塑件制件尺寸。本模具采用一模二件，側(cè)澆口進(jìn)料，注射機采用海天330XC型號，設(shè)置冷卻系統(tǒng)，CAD繪制二維總裝圖和零件圖，UG繪制3D模具圖，選擇模具合理的加工方法。附上說明書，系統(tǒng)地運用簡要的文字，簡明的示意圖和計算等分析塑件，從而作出合理的模具設(shè)計。

Plastic pattern of our country have the present situation of industry in recent years, the plastic pattern of our country has level having greater rising. Large scale plastic pattern have already can produce single set weight to reach the note above 50 ts mould the precision of mould and precise plastic pattern already can reach 3 μ m, even system is precision for 0.5 μ the little modulus gear mould of m and reach the vehicle lamp mould etc. of high optical requirement also already can produce , much cavity plastic pattern already can produce 7800 a mould cavities mould mould, high speed mould aspect the high speed plastic different profile extrusion that can already produce the 4 above extrusion speeds of m/min mould and main profile twin-circuit are squeezed totally , two colour squeeze totally , soft is hard and totally crowded , is rear and totally crowded , reworked material mould extrusion and low foaming steel to share squeeze wait for various moulds. On production means, mould enterprise equipment numerical control melt lead having greater raising, it is more and more that the application surface of the technology of CAD/CAE/CAM has enlarged the adopting of, high speed processing and the etc. advanced technique of RP/RT considerably. Mould standard component is used, cover rate and mould commercialization rate have had the raising of greater range, the proportion of the hot mould of flow path also has greater rising.
The modern molding tool technical development, to a large extent rely on a molding tool to standardize, research, the forerunner's design and manufacturing technique, appropriative tool machine equipments of high-quality molding tool material, technical management etc. of the more important production.The basic characteristic of molding tool profession is a height integration to turn in 21th century, the intelligence turn, gentle turn to turn with network.The target of pursuing is the quality and production efficiency that raises a product and shorten design and manufacturing period and lower production cost and with maximum limit raise the contingency ability of molding tool profession and satisfy customer's demand.It is thus clear that, in the future our country the main development direction of the molding tool industry and technique will be:
1. Popularize vigorously, apply the technology of CAD/CAE/CAM extensively, move towards step by step, is integrated. Modern mould design production should not only emphasize information is integrated, should emphasize technology and popular support more to manage, is integrated. 
2. Rise is large scale, precise , is complex the design with the life mould of long life and make technology, the import that reduces mould step by step is measured , increases the export quantity of mould.
3.Plastics inject type mould, positive application hot flow path popularizes angry supplement or water supplement, inject type, as well as high voltage inject type technology, satisfy the type needs of product.
4. Raise the utilization rate of mould standardization level and mould standard component. Mould standard component is mould foundation and its plenty of applications can shorten mould design production period, at the same time also raise performance characteristics and the production precision of mould apparently, and raise mould quality greatly. The mould commercialization and standardization rate of our country are lower than 30% , advanced country is higher than 70% , annual we will import the mould standard component of considerable quantity from abroad, Its expenses takes up 3%~8% of the molding tool import sum in year around
5. Develop make type and fast production mould fast, fast type production technical, quick production produce mould and the prototype of article, reduce cost, push to market.
6. Study and develop material, equipment and the polished technology of mould actively, satisfy the needs of special product.
7. Popularize application high speed milling, exceed precision processing and complex processing technique and technology, satisfy the needs of mould production.
8. Develop high quality mould material and advanced finishing technology, raise the reliability of mould.
9. Study and apply countrary and the high speed measure technology of mould to project and parallel project, high limit land raise successful rate and the development efficiency of mould.
10. Develop new type technology and mould to satisfy future much subject mutifunction comprehensive product development design technology.
According to the plastic products requirements, understand the use of plastic parts, plastic parts of the process analysis, dimensional accuracy and other technical requirements, selection of plastic parts size.
