| 摘要：塑料模具在当今社会越来越广泛的应用，从电脑、手机、饮料、台灯、水笔、水盆等方面应用极其广泛，可以说从我们的吃穿住行都离不开它。注射成形是成形热塑件的主要方法，因此应用范围很广。注射成形是把塑料原料放入料筒中经过加热熔化，使之成为高黏度的流体，用柱塞或螺杆作为加压工具，使熔体通过喷嘴以较高压力注入模具的型腔中，经过冷却、凝固阶段，而后从模具中脱出，成为塑料制品。本次的毕业设计是吸尘器管座的注塑模的设计，依据产品的数量和塑料的工艺性能确定了以1次分型面注塑模的方式进行设计。模具的型腔采用一模2腔直线排列，浇注系统采用侧浇口成形，推出形式为推板推出机构完成塑件的推出。由于塑件的工艺性能要求注塑模中有冷却系统，因此在模具设计中也进行了设计。本次的设计中参考了大量的文献，还在互联网上查找资料，设计过程比较完整。8296 关键词 ：1次分型面注射模具；侧浇口；内侧抽 Design of injection mold base cleaner Abstract: plastic mold used in today's society is more and more widely, from the computer, mobile phone, beverage, desk lamp, pen, the basin, the application is extremely broad, it can be said that from our food and clothing live line cannot do without it. Injection molding is the main method of forming thermoplastic parts, so a wide range of applications. The plastic injection molding is the raw material into the barrel through the heating and melting, making the high viscosity of the fluid, used as a plunger or screw compression tools, cavity melt through the nozzle into the higher pressure in the mold, after cooling, solidification stage, and then ejected from the mold, a plastic products. This graduation design is the design of injection mold for vacuum tube, based on process performance and number of plastic products are designed with 1 times parting surface of injection mold are determined. The mold cavity using a mold 2 cavity is arranged in a straight line, pouring system adopts the side gate forming, roll out in the form of mechanism to complete the introduction of plastic parts. Because the plastic parts of the process performance requirements of injection mold cooling system, so also in the mold design to design. The design of the reference to a lot of literature, is still on the Internet to find information, the design process is complete.
