【正文】 `I `II Abstract This design needing the thickness of plastic uniform, the surface should be smooth .Considering the size of product is large, so the design uses onemode and onecavity form in this case. The design also use halfstructure to forming the handle of product after analyzing the structure of the product. In order to ensuring the surface smooth, the edge without distortion, we use pneumatic ejection structure. This structure also simplifies the mold structure, economical and practical. Meanwhile, we measured the connection between product quality and the cost. Making the mold of simple structure、 low processing costs of production、 easy processing and usability as much as possible. Key words Mug。 Injection Mould。 Halfstructure。 Pneumatic ejection structure `III 目 錄 摘要 、 關(guān)鍵詞 ........................................ 錯(cuò)誤 !未定義書簽。 Abstract、 Key words ......................................................
