In recent years, the people were getting higher and higher request to lightweight of each kind of equipment and the thing, this has provided a broader market for the plastic products. To be high efficient and costeffective tool to enhance their market shares and development, design is of vital importance. The design of the power plug to carry out research and discussion, and analysis of the characteristics of its technology to introduce the structure of injection mold and die work processes, systems on the process of injection mold design, plastic fittings for power plug structure and forming process analysis, including the location and the molding surface of choice, to determine the number of mold cavity and the cavity flow arrangement and the layout and the choice of gate location, the work of parts of the structure of mold design, the introduction of institutional design, drawing materials under the form of options, such as exhaust design. Through the correct process analysis, design two cavities of plastic die, and determine surface and structural horizontal injection molding machine by paring . As part of a free to use to the socket, therefore, the two leading posts in the socket, by putting out of plastic. The pact design to meet the mass production of products, highprecision, plex shape designed with reference to past experience in injection mold design, b ined with performance parts to simplify the design and use of AutoCAD, pro/e software, such as twodimensional and threedimensional graphics and shortened the production cycle, access to good economic performance. Key words： power plug。 injection mould design。 coredrawing 桂林電子科技大學(xué)畢業(yè)設(shè)計 (論文 )報告用紙 目 錄 引言 ........................................................................................................................................... 1 1 概論 .................................................................................................................................... 2 電源插頭注塑模設(shè)計總體方案 ......................................................................................... 2 設(shè)計基本過程 ..................................................................................................................... 2 2 塑料工藝規(guī)程的分析 .................................................................................................... 3 塑件制件設(shè)計的工藝分析 ................................................................................................. 5 尺寸和精度要求 ............................................................................................................... 5 塑件的表面質(zhì)量 ............................................................................................................... 6 脫模斜度 ........................................................................................................................... 6 計算塑件的體積和重量 ..................................................................................................... 7 3 模具設(shè)計 ........................................................................................................................... 7 注射機的選擇 和校核 ......................................................................................................... 7 型腔數(shù)量的確定和校核 ................................................................................................... 8 注射量校核 ....................................................................................................................... 8 注射壓力的校核 ............................................................................................................... 8 塑件在分型面上的投影面積校核 ................................................................................... 9 塑件在分型面上鎖模力校核 ........................................................................................... 9 注塑機開模行程校核 ..................................................................................................... 10 分型面的設(shè)計 ................................................................................................................... 10 澆注系統(tǒng)設(shè)計 ....................................................................................................................11 主流道設(shè)計 ......................................................................................................................11 分流道 設(shè)計 ..................................................................................................................... 12 澆口設(shè)計 ......................................................................................................................... 12 排溢系統(tǒng)的設(shè)計 ............................................................................................................... 14 成型零件的設(shè)計 ...
