碩士 === 國立臺灣科技大學 === 機械工程系 === 103 === 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.
