摘要

本文針對感應加熱技術用於模具加熱作開發研究，提出兩種通以高頻電流之嵌入式感應線圈和感應線圈整合集中器進行感應加熱快速提高模穴表面溫度之裝置方法。透過嵌入式感應線圈快速加熱模溫這項技術並可於塑料開模與合模注入階段持續加溫，解決射出成型製程流動阻力大而造成塑料流動性不佳之成型困難。顯示出高模溫的重要性所以本技術高週波感應加熱可達到快速加熱、控制加熱溫度等優點，降低生產成本以達到同時兼顧縮短成型週期與高生產量率之目標。
本論文主要利用ANSYS APDL/ ANSYS Maxwell 和ANSYS Multiphysics軟體模擬嵌入式感應線圈與集中器之整合對於模具之公模仁加熱的情形作與模擬熱油機提升模溫做比較，對ANSYS應用於含加熱源模具溫度場分析與驗證做討論，並對電磁與熱耦合分析應用於感應線圈設計進行分析，以進行感應加熱模擬尋找相關操作參數並驗證分析與實際的可行度，確定ANSYS軟體在分析含加熱源模具溫度場之可行性。本研究利用現有射出成型標準模具規格實際設計開發一組模具，同時設計出特殊線圈與以電木材質之機構固定線圈於模具上配合射出成型製程步驟進行升溫與冷卻做模擬分析。

My research and development is to aim for mold heating induction heating technology. There two ways of propose with passing a high-frequency current through the induction coil and embedded integrated with concentrator method for rapidly increased the surface temperature of the mold cavity. Mold temperature of this technology through rapid heating is induction coil embedded in the plastic injection mold to be heated up, this phenomenon solving injection molding process flow resistance caused by poor liquidity of plastic molding difficulties. That the importance of the technology of rapid heating mold temperature will reduce production costs in order to achieve objectives while taking into account for shorten molding cycle and high production rates.
This paper using ANSYS APDL / ANSYS Maxwell for comparison and mainly used ANSYS Multiphysics simulation software to simulate embedded induction heating coil and oil heating to make a comparison of increasing mold temperature. ANSYS used in mold temperature field analysis and verification do discuss and theory , the coupling of electromagnetic and thermal analysis is applied to the induction coil design is analyzed for induction heating simulations to find relevant operating parameters and verify the credibility of the analysis to determine the feasibility of heating source mold temperature field analysis with ANSYS software .
In this study, the use of existing standard injection molding mold design and development of a set of specifications of the actual mold with designing a special coil and institutional fixed coil phenolic material in the injection molding process with the heating and cooling steps to simulate and analyze the mold.
