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，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(fù)雜的精密塑件。本論文完成了瓶蓋注射模模具的設(shè)計(jì)及模具的虛擬拆裝。
 畢業(yè)設(shè)計(jì)過程中主要利用Pro/E、Soldworks和AutoCAD工具軟件，充分發(fā)揮計(jì)算機(jī)輔助設(shè)計(jì)的優(yōu)越性，實(shí)現(xiàn)了模具設(shè)計(jì)設(shè)想。首先分析塑件的結(jié)構(gòu)工藝性，設(shè)計(jì)單分型面模具結(jié)構(gòu)形式。然后在Pro/E EMX模塊中完成了模具成型零部件的推出機(jī)構(gòu)、導(dǎo)向機(jī)構(gòu)、結(jié)構(gòu)零部件和冷卻系統(tǒng)等各個(gè)機(jī)構(gòu)的3D建模及裝配，并在AutoCAD中繪制了整幅模具的二維裝配圖，最后運(yùn)用Soldworks中對瓶蓋注射模工作及拆裝過程設(shè)定運(yùn)動(dòng)約束，進(jìn)行虛擬運(yùn)動(dòng)演示。總之，所設(shè)計(jì)的模具結(jié)構(gòu)簡單，機(jī)構(gòu)運(yùn)行可靠，3D設(shè)計(jì)及虛擬拆裝直觀明了。對注射模設(shè)計(jì)及制造有一定的借鑒意義。

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
