【正文】 品，每轉(zhuǎn)動(dòng)一次，這套設(shè)備可注塑成型 64個(gè)制品。 (2)多工位、連續(xù)注塑技術(shù)的應(yīng)用。 一般來(lái)說(shuō)，國(guó)外的模具工業(yè)起步比較早，發(fā)展也比較靠前，技術(shù)也比較成熟 ,現(xiàn)在注塑成型技術(shù)在向多工位、高效率、自動(dòng)化、連續(xù)化、低成本方向發(fā)展。而塑料注射模在模具中所占的分量越來(lái)越大，其發(fā)展也非常迅速，大有凌駕其它模具之上的趨勢(shì)。隨著塑料工業(yè)的發(fā)展，社會(huì)對(duì)塑料制品的需求愈來(lái)愈大。輕工、軍工、冶金及建材等行業(yè)大部分產(chǎn)品和生產(chǎn)都離不開(kāi)模具 [3]。模具成形有優(yōu)質(zhì)、高產(chǎn)、低消耗和低成本等特點(diǎn)，因此得到了廣泛應(yīng)用。模鍛件、沖壓件、擠壓和拉拔件等，都是使金屬材料在模具中發(fā)生塑性變形而獲得的；壓鑄零件、粉末冶金零件也在模具中充填加工成形的；而塑料、陶瓷、玻璃制品等非金屬材料的成形加工也多是依靠模具。模具是壓力加工或其它成形加工工藝中，使材料變形制成產(chǎn)品的一種重要工藝裝備，應(yīng)用廣泛。用模具制造零件以其效率高，產(chǎn)品質(zhì)量好，材料消耗低，生產(chǎn)成本低而廣泛應(yīng)用于制造業(yè)中 [1]。 through painting assembly drawing, part drawings, and further deepen the CAD system proficiency, a better understanding of the various parts of mold.
