吸尘器是一种广泛应用的家用电器，其面板盖是塑料制品，一般采用注射成型；其注射模制造精度要求比较高，且成型零部件一般采用数控加工，设计课题为吸尘器面板盖注射模完成了制造工艺设计及CAM模拟。
首先对已有吸尘器面板盖注射模进行结构工艺性分析，指出了其在功能、寿命、加工难度等方面的缺陷，给出了改进设计方案。然后为模架、支撑板等结构零部件设计机械加工工艺路线，并为型芯和型腔等成型零部件设计数控加工工艺路线。最后利用UG CAM模块对型芯、型腔进行了数控模拟加工，生成了NC程序。
总之，吸尘器面板盖注射模的制造工艺路线合理可行，数控加工的CAM模拟直观清晰，对注射模的设计和制造有较佳的借鉴价值。

Manufacturing Procedure Design and CAM Simulation of the Injection Mold for a Plate Cover of Vacuum Cleaner
Abstract
The Vacuum cleaner is one of widely used household appliances, the plate cover of it being made of plastics by the injection molding. The injection mold has high precision, the forming parts being manufactured by numerical control (NC) machining. In this design dissertation, the manufacturing procedures were designed for all parts of charger cover injection mold and the CAM simulation was completed for the forming parts of the mold.
Firstly the processability of the plate cover injection mold was analyzed to find defects of function, life, processing difficulty, and the improved design was put forward. Then, the general machining procedures were completed for the structural components in the mold, including the fixing and supporting plates in the moldbase. The NC machining procedures were completed for the forming components after the numerical control machines and the machining parameters were determined and the manufacturing charts were listed in the affiliated tables. At last, the CAM simulation of the core and the cavity were completed, and the NC programs were generated automatically in the UG NX software packages.
In short, the designed manufacturing procedures of the vacuum cleaner plate cover injection mold components are proper and feasible, and the CAM simulation has good visibility. The design is of good significance for the design and manufacturing in the injection molding industry.
