中文摘要
模具生產(chǎn)的工藝水平及科技含量的高低,已成為衡量一個(gè)國(guó)家科技與產(chǎn)品制造水平的重要標(biāo)志,它在很大程度上決定著產(chǎn)品的質(zhì)量、效益、新產(chǎn)品的開發(fā)能力,決定著一個(gè)國(guó)家制造業(yè)的國(guó)際競(jìng)爭(zhēng)力。
根據(jù)國(guó)內(nèi)和國(guó)際模具市場(chǎng)的發(fā)展?fàn)顩r,有關(guān)專家預(yù)測(cè),未來(lái)我國(guó)的模具經(jīng)過行業(yè)結(jié)構(gòu)調(diào)整后,將呈現(xiàn)十大發(fā)展趨勢(shì):一是模具日趨大型化;二是模具的精度將越來(lái)越高;三是多功能復(fù)合模具將進(jìn)一步發(fā)展;四是熱流道模具在塑料模具中的比重將逐漸提高;五是氣輔模具及適應(yīng)高壓注射成型等工藝的模具將有較大發(fā)展;六是模具標(biāo)準(zhǔn)化和模具標(biāo)準(zhǔn)件的應(yīng)用將日漸廣泛;七是快速經(jīng)濟(jì)模具的前景十分廣闊;八是壓鑄模的比例將不斷提高,同時(shí)對(duì)壓鑄模的壽命和復(fù)雜程度也將提出越來(lái)越高的要求;九是塑料模具的比例將不斷增大;十是模具技術(shù)含量將不斷提高,中高檔模具比例將不斷增大,這也是產(chǎn)品結(jié)構(gòu)調(diào)整所導(dǎo)致的模具市場(chǎng)未來(lái)走勢(shì)的變化。
模具制造技術(shù)現(xiàn)代化是模具工業(yè)發(fā)展的基礎(chǔ)。隨著塑料制品在我們身邊應(yīng)用的越來(lái)越廣,許多金屬件慢慢被一些改性性塑料所代替。塑料工業(yè)得到了迅猛的發(fā)展,它的發(fā)展帶動(dòng)了塑料注射模的發(fā)展,使其成為當(dāng)今很熱門的行業(yè)。

ABSTRACT
Die in accordance with domestic and international market development, the experts predicted that China's future after the mold industry structure adjustment, the top 10 will show a trend of development: First, the increasingly large die and the other is the precision molds will become more and more high-third is Multi-functional complex mold will be further developed; Four die in a hot runner in the plastic mold will gradually increase the proportion of Fifth mold and gas-assisted injection molding, and other high-voltage adaptation of the mold will have greater development of standardization and 6 Die Die is the standard The pieces will be increasingly widespread application; seven rapid economic mold is very broad prospects for; eight die-casting mould is the ratio will continue to increase, while the die-casting mould of the magnitude and complexity of life will also be raised higher and higher requirements for the plastic mold of the 9 Will continue to increase ratio of 11 is the mold will continue to improve the technological content, in the proportion of high-grade mold will continue to increase, this product is the result of the restructuring mold the future trend of changes in the market.
Die die manufacturing technology modernization is the basis for industrial development. With the plastic products around us of the increasingly wide, many pieces of metal by some modification of the slowly replaced by plastic. Plastics Industry has been the rapid development, its development has driven the development of plastic injection mould, making it very popular in today's industry.

Key words: pieces of metal, plastic molds, injection -
