隨著CAD/CAM軟體不斷的更新演進,要設計一套模具的3D CAD模型已經不是一件難事,市面上的主流軟體更提供了針對模具設計的模組,使用者只要依照既定流程進行操作就能設計出一套完整的模具。本論文旨在參考現有套裝軟體的模具設計架構,開發一套具有輕量化特性的「塑膠射出成型模具之標準元件設計導引系統」,該系統包含「標準模具元件資料庫」及「標準模具元件設計」兩個主要模組。
在「標準模具元件資料庫」方面,本論文採用三層式架構的概念,在ASP.NET開發平台中開發網路資料庫網頁,配合微軟公司的IIS伺服器架設主機端網路伺服器,網頁數據資料則儲存在SQL資料庫中,以利後續模組調用。
在「標準模具元件設計」方面,本論文使用Siemens公司的3D CAD/CAM軟體NX所提供的二次開發工具NXOpen,開發三類與模仁相關的標準零件 滑塊脫模機構、頂出銷與注道導套之自動化組裝及設計變更的功能。在組裝這些標準零件的同時,系統能依據組裝位置自動計算出零件的長度,並自動在模座上產生放置這些零件所需的空間,以避免標準零件與模座有干涉的現象。另一方面,滑塊脫模機構的所有零件是由使用者從網路資料庫的網頁下載而得,在用戶端不須預先儲存大量零件檔,能節省硬碟儲存空間並減少運算時間,後續資料更新也更加便捷,以達成「輕量化系統」的目標。
As CAD/CAM software is constantly evolving, designing 3D CAD models for a set of plastic injection molds is not a difficult task. The mainstream software in the market even provides a module for mold design. As long as the user follows the established operating processes, he or she can design a complete set of molds. In this thesis, we refer to the mold design architecture of existing package software and develop a design guiding system for standard components of a plastic injection mold with lightweight features. This system includes two major modules: a standard mold components database and a standard mold components design.
In terms of the standard mold components database, we adopted a three-tier architecture to develop the web-based database website in the ASP.NET development platform, and in coordination with Microsoft's IIS server, a web server set up on the host side. The site data is stored in an SQL database to facilitate the follow-up module call function.
For the standard mold components design, we used the application programming interface NXOpen provided in Siemens’s 3D CAD/CAM software NX to develop the function of automated assembly and automated design change for three types of standard parts related to the mold cavity: slider releasing mechanism, ejector pin and sprue bushing. By assembling these standard parts, the system can calculate the lengths of parts based on the assembly position and generate the required cavity for placing these parts on the mold base automatically to prevent the standard parts from interfering with the mold plates. On the other hand, all parts of the slider release mechanism were obtained by a user downloading them from an internet database. As the client does not need to pre-store the massive files for the parts, it saves storage space on the hard disk and reduces operation time. The subsequent information updates are also convenient. All these features help achieve the goal of being a lightweight system.
