塑料齒輪模具設計及其型腔仿真加工
摘 要:本課題來源於鹽城羽佳塑業,任務是塑料齒輪模具設計及其型腔仿真加工.註射成型是塑料成型的壹種重要方法,它主要適用於熱塑性塑料的成型,可以壹次成型形狀復雜的精密塑件。本課題就是將雙聯齒輪作為設計模型,將註射模具的相關知識作為依據,闡述塑料註射模具的設計過程。
本設計對雙聯齒輪進行的註塑模設計,利用proe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,確定了註射成型工藝過程並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。 最後用mastercam仿真加工型腔。
本課題通過對雙聯齒輪杯的註射模具設計,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。

The design of gear plastic injection mold and cavity simulation processing
Abstract: The subjects come from the Yujia Plastic Corporation. Task is what the design of gear plastic injection mold and cavity simulation processing. Plastic injection molding molding is an important method, which is primarily applicable to thermoplastic plastic molding, Molding can be a complex shape of precision plastic parts. To study the topic ,we make double-gear the design model, make the injection mold-related knowledge the basis for elaborate plastic injection mold design process.
In the designment we design double-gear with the injection mold design, using software proe to plastic parts to solid modeling, and making technics analysis to the structure of Plastic Parts for the process.We definite the design,and identify the injection molding process as well as some specific details of the calculation and verification.The structure of such a design can be used to ensure reliable Die work ,to ensure cooperation with the other parts of the tie. Finally,simulation processing cavity with mastercam .
we have consolidated and deepened the learning, gain a satisfied result, achieve the desired design intent through the process of double-gear mold design.
