隨著塑膠產品的使用日益頻繁，在全球瞬息萬變的市場上，企業面臨產品生命週期縮短、削價競爭與成本過高等問題，因此需加速產品的開發，並將作業流程與製程標準化，以提升產業競爭力。本論文在ASP.NET開發平台中建置標準模座元件之網路資料庫平台，並使用Siemens公司的3D CAD/CAM軟體NX所提供的二次開發工具NXOpen，開發一套「塑膠射出成型模具之模座設計導引系統」，讓使用者於網頁端選擇並下載標準模座檔案，接著於NX環境中自動組裝模板，並進行下列模座設計工作：(1)導入模仁：組裝模仁組件，然後挖出放置該模仁所需的模穴，(2)自動化組裝標準零件：自動化組裝各個模座零件，並自動化產生為數眾多的模具標準零件，且組裝至各個標準零件專屬的模板上，(3)模具設計變更：由使用者進行模座設計變更，以因應模具設計的需求。本論文以網際網路為基礎，開發一個以設計變更為導向的模座零件資料庫系統，該系統提供一個簡易操作的使用者介面，讓使用者選取模座規格，而系統會根據該模座規格自動計算出相關的幾何參數，以及自動抓取每個模座元件所需之資訊，並能自動化對各個模座元件進行修改與重建。接著將所有的模座元件導入「模座設計導引系統」中，進行導入模仁、自動化組裝標準零件與模具設計變更共三項工作。使用者只需在NX系統中，透過簡易的操作介面，便能快速完成模座設計，因此可提升模具產品作業流程的速度，並減少模具設計工程師的人為疏失與錯誤。

With the increasingly frequent use of plastic products in a rapidly changing global market, companies face problems such as shorter product life cycles, price competition, and high capital costs. There is therefore a need to accelerate the development of products and standardize the operation and manufacturing processes to enhance industrial competitiveness.In this thesis, we built a web-based database website for standard mold base components in the ASP.NET development platform and used the application programming interface NXOpen provided by Siemens’s 3D CAD/CAM software NX to develop a design guiding system for mold bases of plastic injection molds. This system enables users to select and download the standard mold base files from the web server and automate assembly of mold plates and conduct the following mold base design work in NX: (1) import the mold assembly: defining the mold cavity, and cut out the required mold cavity that is placed in the mold; (2) automate assembly of mold standard parts: automate assembly of all mold base components, automate generation of large numbers of mold standard parts, and assemble the standard parts onto each exclusive mold plate; (3) changing mold design: the mold design change was performed by a user in response to the requirement of mold designs.In this thesis, we develop an internet-based design-change-oriented database system for mold base parts. This system provides an easy-to-operate user interface, allowing the user to select the mold base specifications, calculate the related geometric parameters, and retrieve the required information for every mold base component automatically. The system can also be used to automate the modification and rebuilding of each mold base component. Therefore, all mold base components were imported into the mold base design guiding system to perform the three tasks of import the mold assembly, automate assembly of mold standard parts, and changing the mold design. By using the simple operating interface in the NX system, the user is able to complete the mold base design quickly, thus enhancing the speed of the operational workflow of mold products, and reducing the human negligence and error of the mold design engineer.
