摘  要
 論文首先通過(guò)數(shù)據(jù)，分析了注塑模具業(yè)的發(fā)展現(xiàn)狀及趨勢(shì)。通過(guò)教學(xué)零件和所用的原料分析，探討了制件的注塑模具成型工藝，設(shè)計(jì)了一模兩腔的塑料模具。在教學(xué)零件注塑模具設(shè)計(jì)中主要確定了模具結(jié)構(gòu)方案，包括分型面的確定，澆注系統(tǒng)和排氣系統(tǒng)的確定，頂出方式的選擇，模具材料的選擇和強(qiáng)度計(jì)算，主要成型零件、結(jié)構(gòu)零件的結(jié)構(gòu)形式確定，模具各部件的強(qiáng)度校核，成型零件工作尺寸計(jì)算等。 而后，利用Solidworks進(jìn)行了產(chǎn)品的三維造型，并通過(guò)IMOLD模具模塊的設(shè)計(jì)，設(shè)計(jì)了模具的三維模型以及裝配。本文所設(shè)計(jì)的模具具有結(jié)構(gòu)簡(jiǎn)單、運(yùn)動(dòng)可靠和排氣良好等優(yōu)點(diǎn)，特別適用于本制品的復(fù)雜的形狀。本文充分利用現(xiàn)代三維CAD設(shè)計(jì)軟件，利用其自頂向下的功能，運(yùn)用裝配分析工具，檢查了模具的干涉可能性，驗(yàn)證了設(shè)計(jì)結(jié)果，充分展現(xiàn)了3D在模具設(shè)計(jì)中的良好應(yīng)用能力。

Abstract
 The current situation and development prospect of injection mold of automobiles are analyzed at first based on data in this paper. Than the injection mold technology of Teaching mold components is discussed by analyzing the work-piece and raw material .The author determined the parting surfaces and the gating system and Release the organization, cooling system etc, choosed the injection molding machine，calculated the sizes of the molding parts. adopted to sprinkle directly in the design, make use of to keep lead the pillar direction fixed position, push the pole crest to anticipate, and carried on the choice to the material of the molding tool. The author also choosed the materials of the mold. The structure designed in such way can ensure the reliable running of the mould. Then use Solidwoks products for the 3-D modeling,correctly grasp IMOLD mold module design techniques and methods, and completed the three-dimensional modeling of mold and assembly. In this paper, the die is simple, reliable and sports exhaust good advantages, particularly applicable to the products of complex thin shapes. By utilizing modern 3D CAD design software, using its top-down function, use of analytical tools assembled, examined the possibility of the interference of mold to verify the design, fully displayed in a 3D mold design of a good application ability.
