【正文】 1 摘 要 近年來，我國家電工業(yè)的高速發(fā)展對模具工業(yè)，尤其是塑料模具提出了越來越高的要求， 2021 年，塑料模具在整個模具行業(yè)中所占比例已上升到 30%左右，據有關專家預測，在未來幾年中，中國塑料模具工業(yè)還將持續(xù)保持年均增長速度達到 10%以上的較高速度的發(fā)展。國內塑料模具市場以注塑模具需求量最大，其中發(fā)展重點為工程塑料模具。 注射成型是塑料成型的一種重要方法，它主要適用于熱塑性塑料的成型，可以一次成型形狀復雜的精密塑件。本課題就是將小家電的榨汁機的料桶杯作為設計模型，將注射模具的相關知識作為依據，闡述塑料注射 模具的設計過程。 本設計對榨汁機料桶杯進行的注塑模設計，利用 UG 軟件對塑件進行了實體造型，對塑件結構進行了工藝分析。明確了設計思路，確定了注射成型工藝過程并對各個具體部分進行了詳細的計算和校核。如此設計出的結構可確保模具工作運用可靠，保證了與其他部件的配合。最后用 autoCAD 繪制了一套模具裝配圖和零件圖。 本課題通過對榨汁機料桶杯的注射模具設計，鞏固和深化了所學知識，取得了比較滿意的效果，達到了預期的設計意圖 關鍵詞： 塑料模具；注射成型；模具設計； 2 Abstract In recent years, China39。s household electrical appliance industry in the development of highspeed tooling industry, in particular the plastic mold of the everincreasing demands. In 2021, the plastic mold industry in the entire Die share has risen to 30% According to the experts predict that in the next few years, China plastic mold industry will continue to maintain an average annual growth rate of 10% over the high rate of development. Domestic market to plastic mold injection mold greatest demand, which focused on the development of engineering plastics die. Plastic injection molding molding is an important method, which is primarily applicable to thermoplastic plastic molding, Molding can be a plex shape of precision plastic parts. Is the topic of small appliances Juicer the drums Cup as a design model, the injection moldrelated knowledge as a basis for elaborate plastic injection mold design process. The design of Orange drums Cup for the injection mold design, the use of software UG plastic parts for the solid modeling, Plastic Parts of the structure analysis for the process. Defined the design, determine the injection molding process as well as some specific details of the calculation and verification. The design of such a structure can be used to ensure reliable Die work to ensure that the other parts of the tie. Finally, a set of auto mapping mold parts and assembly plans. The subject of Orange drums Cup injection mold design, and to consolidate and deepen the learning, has been fairly satisfied with the results, achieved the desired design intent Keywords : plastic mold。 injection molding。 Mold design。 3 目 錄 摘 要 ........................................................................................................................... 1 Abstract ......................................................................................................................... 2 目 錄 ......................................................................................................................... 3 第 1 章 緒 論 ........................................................................................................... 5 第 2 章 肥皂盒塑料件 ............................................................................................... 7 塑件的原材料分析 ........................................................................................... 7 塑件的結構和尺寸精度及表面質量分析 ....................................................... 8 塑 件的結構分析 ...................................................................................... 8 塑件尺寸精度的分析 .............................................................................. 8 表面質量的分析 ...................................................................................... 8 塑件的體積重量 ............................................................................................... 8 塑件的注射工藝參數的確定 ....................
