摘要
進入二十一世紀以來，中國塑料工業(yè)取得了令世人矚目的成就，實現(xiàn)了歷史性的跨越。蓬勃發(fā)展的中國塑料工業(yè)，在中國現(xiàn)代化經(jīng)濟建設中發(fā)揮著越來越大的作用。塑料制品在人們的日常生活中隨處可見，因此其注塑模具的需求也日益增多，市場前景廣泛，而且因為不同塑件的外形不同，注塑模具也就有了很大的不同。
本設計是關于頂塊的注塑模具設計，通過注塑機注塑成形零件。首先運用UG對塑件進行三維圖的繪制，然后轉成二維模型，進行導出，再運用AutoCAD軟件修改二維模型。介紹了注塑機的選用，塑件的選材，澆注系統(tǒng)的設計，分型面及型腔數(shù)目的設計，導向、脫模及冷卻系統(tǒng)的設計等，以及對模具的校核。 隨著塑料加工工業(yè)持續(xù)快速發(fā)展，塑料制品在工業(yè)、農業(yè)、軍事及人民生活的各個領域得到廣泛的應用，塑料制品的研究、生成與應用開發(fā)得到迅速發(fā)展，塑料模具的設計、制造技術也隨之不斷提高。塑料制品業(yè)是一個新興大行業(yè)。隨著我國國民經(jīng)濟持續(xù)高速發(fā)展已逐步發(fā)展壯大，自上世紀90年代以來，塑料行業(yè)一直保持在10%以上的增長速度，已成為輕工業(yè)的支柱產業(yè)之一。隨著CAD/CAM/CAE技術的引用，更是顯著提高了模具設計的效率，減少模具設計過程中的失誤，提高了模具和塑件的質量，縮短了生產周期，降低了模具和塑件的成本。

Abstract
Into the 21th century, China's plastics industry has made achievements that attracted worldwide attention, achieved a historic leap. China's booming plastics industry, economic modernization in China is playing an increasingly important role. Plastic products in people's daily life everywhere, so the injection mold growing demand, broad market prospects, but also because of different shape with different plastic parts, injection molds will have a big difference.
This design is about theTop block injection mold design, injection molding parts by injection molding machine. First use of UG on plasticPieces of three-dimensional mapping, and then turn into a two-dimensional model, export, re-use of AutoCAD software to modify the two-dimensional model. Describes the selection of injection molding machines, plastics material selection, design of gating system, the number of sub-surface and cavity design, direction, stripping and cooling system design, as well as checking on the mold. With the sustained and rapid development of plastic processing industry, plastic products in the industrial, agricultural, military and people's life has been widely used in various fields, plastic products, research, generation and application development is the rapid development, plastic mold design and manufacturing technology with S continues to increase. Plastic products industry is an emerging industry. With the rapid development of China's national economy has gradually grown since the last century, 90 years, the plastics industry has remained at over 10% growth rate, has become one of pillar industries in light industry. With the CAD / CAM / CAE technology, reference, but also significantly improve the efficiency of mold design, mold design process to reduce errors and improve the quality of molds and plastic parts, shortening the production cycle, reducing mold and plastic parts Costs.
