摘 要
随着中国工业不断地发展，模具行业也显得越来越重要，塑料模所占的比例也越来越大。本设计进行了衬垫的注塑模设计，对零件结构进行了工艺分析。根据零件的结构和生产批量以及零件精度，选取一模一腔的标准模架，采用单分型面，采用的浇注系统是从塑件的中央环形处向两侧浇注，主流道从模具中央直下，分流道在动模型芯上。选择了注射机，计算了成型零部件的尺寸。根据零件所采用的材料成型特点，采用冷却水管对模具进行降温。由于零件的尺寸比较小，利用模具顶出杆与顶出孔的配合间隙，顶块和脱模板与型芯的配合间隙等来排气。采用侧浇口。利用直导柱导向，推杆顶料。由于抽芯距离较短，为了使模具结构简单，采用斜导柱侧抽芯方式，并对模具的材料进行了选择。如此设计出的结构可确保模具工作运用可靠。最后对模具结构与注射机的匹配进行了校核。

ABSTRACT
With China’s industries continue to develop and die industry is also becoming increasingly important, the proportion of plastic mold is also growing. The design of the liner injection mold design, parts of the structure analysis for the process. According to parts of the structure and production volume and precision parts, select a mode of a cavity-mode standard, single-face and The system is pouring from the plastic parts of the central ring to the side pouring Department, the mainstream mold Road from the Central Pavilion, Road diversion moving on the core model. Choose the injection machine, computing the size of the molding parts. Under the parts used in the molding characteristics, the right mold cooling pipes for cooling. As part of a relatively small size, use of die out the top bar and head out of the hole with Gap, from the top block and core template and the other with space to exhaust. The adoption of side gate. Direct use of derivative-oriented, putting the material. As the core pulling shorter distances, in order to enable Die simple structure, using bevel-side core-pulling, also mold the material of choice. The design of such a structure can be used to ensure reliable die. Finally, the injection mold structure and the matching machine was calibrated.
