摘   要
 近年来，我国家电工业的高速发展对模具工业，尤其是塑料模具提出了越来越高的要求，注射成型是塑料成型的一种重要方法，它主要适用于热塑性塑料的成型，可以一次成型形状复杂的精密塑件。本论文完成了瓶盖注射模模具的设计及模具的虚拟拆装。
 毕业设计过程中主要利用Pro/E、Soldworks和AutoCAD工具软件，充分发挥计算机辅助设计的优越性，实现了模具设计设想。首先分析塑件的结构工艺性，设计单分型面模具结构形式。然后在Pro/E EMX模块中完成了模具成型零部件的推出机构、导向机构、结构零部件和冷却系统等各个机构的3D建模及装配，并在AutoCAD中绘制了整幅模具的二维装配图，最后运用Soldworks中对瓶盖注射模工作及拆装过程设定运动约束，进行虚拟运动演示。总之，所设计的模具结构简单，机构运行可靠，3D设计及虚拟拆装直观明了。对注射模设计及制造有一定的借鉴意义。

Abstract
 In recent years, the development if the household electrical appliance industry at highspeed demands, the mold industry, especial the plastic mold. The injection molding is one most  important moulding method, which is primarily applied to the thermoplastic products. In this paper, the injection mould design for one bottle lid and the virtual reality of the disassembly and the motion for the mold was completed.
 During the design process the Pro/E, AutoCAD and SolidWorks software tools were used, having many advantages of computer-aided design, to achieve the mold design and the virtual reality. First the structure of the plastic parts was analyzed and designed the single-parting surface. And according to the results of these calculations, the Pro/E EMX modules was used to complete the 3D modeling if molding parts and other mold assembles such as the ejection system, the oriented system, the structures parts and the cooling system. And the AutoCAD was used to draw the general assembly and the parts drawing two-dimentional. At last SolidWorks was used to completed virtual reality of the disassembly and the motion of the mold. In a word, the injection mold structure is simple..And the mechanism is reliable, the 3D design and virtual disassembling being ocular and clear
