摘 要：本課題設計是對臺燈罩模具設計和型腔仿真加工。設計過程中采用Pro/E Wildfire 4.0進行三維造型、分型面設計和模流分析，用CAD進行零件圖和裝配圖的繪制，用Master cam 9.1進行模具型腔的仿真加工。
 根據制品的體積、質量和要求選定注塑機型號，再確定模具型腔為一模二腔；考慮模具外觀要求等諸多因素，選取分型面在塑件的底面；為使塑件能夠快速均勻的冷卻，冷卻流道布置為環繞式；澆口采用潛伏式澆口，使兩個型腔同時得到均勻的充填和成型；由于制品需要側抽芯，經過驗證，抽芯機構采用最常用的斜導柱分型與抽芯機構；頂出機構是制品的脫模裝置，依據塑件結構采用8根頂桿；由于塑件是薄壁結構可能出現注塑不完整，通過模流分析驗證注塑流體可以充滿型腔，符合設計要求。分析型腔的加工工藝，在Master cam 9.1中完成刀具路徑設定，確定數控加工代碼，通過仿真加工確定是否滿足加工要求。
   通過使用模具設計應用軟件，使模具設計效率大大提高，符合設計要求。

The Design and Simulation Processing
of Reading Lamp Mold
Abstract: This subject design is to design the reading lamp mold and make the simulation processing of the mold cavity. In the design process, Pro/E Wildfire 4.0 were used to construct on the three dimensional modeling, make parting surface and make analys on mold flows, CAD were used to make parts drawing and assembly drawing,Master cam 9.1 were used to carry on the mold cavity simulation processing.
 This mold according as the injection molding machine model and the efficient deterministic cavity which assigns based on the factory is two cavities ; Considered many factors such as appearance requirements, a selection divided profile is modeling a bottom surface; In order to cause to model to be able the fast uniform cooling, cools the flow channel arrangement for to surround the type; Uses a balance -like divided flow channel, the side runner, at the same time the causing cavity obtains even fills and takes shape; prop up the organization is the product taking off patterns installment, go on the basis models a structure to use 8 mandril ; Because models are the thin-wall construction possibly appears casts not completely, get across flows the analysis confirmation the mold to cast the fluid to be possible the filling cavity, conforms to the design requirement. The analysis cavity processing technics, completes the cutting tool way hypothesis in Master cam 9.1, the definite numerical control processing code, through the simulation processing determined whether satisfies the processing request.
    Through the use mold design application software, makes the mold rated capacity to enhance greatly, conforms to the design requirement completely.
