Abstract

中文摘要 在台灣，射出機製造業扮演著關鍵的角色，從我們日常使用的塑料水瓶到汽車的車門等產品都可能透過射出成型製造。射出機的重要性在於它提供了高效率且符合成本效益的製造方法，因此對於台灣的製造業而言，射出機是一項不可獲缺的製造工具。 在射出機中，鎖模單元充當至關重要的角色。這個機構的運作直接影響著產品的品質和生產效率。因此，本專題旨在研究和設計一個全電動式285AE臥式射出機型的鎖模單元其後方之調模機構。我們將運用所學機械設計知識，專注於正齒輪的設計，包含了齒數計算、節圓直徑選定和干涉分析等。透過這個專案，我們的目標是實現高效率和符合經濟效益的鎖模單元，以應對製造業在環保永續方面的需求挑戰。具體任務包括正齒輪的精確設計、齒輪與哥林柱的相互運轉以及選配合適的減速（調模）馬達，使其在理想的時間內完成鎖模單元的調整移動。這個專題將為臥式射出機鎖模單元的設計和性能提供實用和可行的解決方案。

Abstract In Taiwan, the injection molding industry plays a crucial role, as products ranging from plastic bottles used in our daily lives to car doors are manufactured through injection molding. The importance of injection molding lies in its provision of efficient and cost-effective manufacturing methods, making it an indispensable tool for Taiwan's manufacturing industry. Within injection molding machines, the clamping unit assumes a vital role. The operation of this mechanism directly impacts the quality and productivity of products. Therefore, this project aims to research and design a clamping unit for a 285-ton all-electric horizontal injection molding machine, specifically focusing on reducing the adjusting time of the tail plate or rear platen. Fundamental knowledge in mechanical design is required, particularly focusing on the design of spur gears, including tooth count calculations, selection of pitch circle diameter, and gear mesh interference analysis. Through this project, our goal is to achieve an efficient and cost-effective clamping unit to address the demand challenges in environmental sustainability faced by the manufacturing industry. Specific tasks include precise design of spur gears, ensuring smooth meshing between spur gears and the thread on tie bar, and selecting suitable speed reduction gear (mold adjustment) motors to enable timely adjustment of the clamping unit within 3.5 minutes. This project aims to provide practical and feasible solutions for the design and performance of clamping unit in horizontal injection molding machines.
