指導教授 : 陳夏宗

摘要


由於綠色節能製造的意識抬頭與產品設計的多樣化,為了達到 產品表面亮麗成品與移動式感應加熱之技術為當下主要的發展目 標。其中,2D 模面溫度及3D 模面溫度的控制為成品尺寸與生產良 率的重要條件之一。現階段在固定式感應加熱應用上,遭遇到在加 熱時模面會有溫度不均勻的現象,而固定式感應加熱應用在3D 模面 加熱上的溫度不均勻為更明顯,移動式感應加熱(IHTC)可讓溫度均 勻分佈模具表面溫度之優點,但其水冷結構應用在移動式感應加熱 上會讓水冷結構故障較多產生之問題仍須克服。 本研究目的為探討移動式感應加熱技術對摸具表面溫度之影 響。實驗中以固定式感應加熱及移動式感應加熱,固定式感應加熱 做固定加熱3 秒,移動式感應加熱將分成移動延遲控制0.05 秒及0.1 秒及0.2 秒,並同時限制加熱時間分成2 秒、4 秒、6 秒,測試不同 加熱時間及不同延遲時間時之影響並實驗比較結果,以驗證分析溫 度均勻之可行性。 實驗結果顯示,固定式感應加熱及移動式感應加熱兩者比較結 果,移動式感應加熱在模面均溫效果較為優異,以實驗數據顯示當固 定式感應加熱在加熱3 秒時模面溫度最高及最低溫度會相差約80 度,當使用移動式感應加熱後,模面最高溫及最低溫度可以控制在最 小範圍約10 度左右。而在案例分析上,將以實際成品來驗證其可行 性,驗證結果顯示移動式感應熱讓模具表面溫度分佈均勻,且利用三 角度光澤計驗證咬花產品的效果,光澤度明顯降低且符合預期,此證 明移動式感應加熱可行性。

Due to various requires of green manufacturing and high quality product surface design. The painting free, no welding line and high gloss surface quality plastic product has become the most important purpose of advanced molding technology. It’s well known that high mold temperature technology may provide great contributions to solve these problems. However, the following issue is the obvious increasing of cycle time. The new development, dynamic mold temperature control (DMTC) technology, is the only way to reach the high mold temperature molding and without increasing cycle time. Induction heating combine with cooling water temperature control (IHTC) is the most suitable way among DMTC to get high heating and cooling rate for the only mold surface temperature control. The purpose of this experiment is to study the influence of the moving induction heating on mold surface temperature. This experiment compares inner induction heating and the moving induction heating the former was set to be heated for 3 seconds, then the latter was separated to terms which mobile controlling delay 0.05,0.1 and 0.2 second in imposing restrictions on heating time of 2, 4 and 6 seconds. To test the influences of different heating time and delay time, and then compare results, are all for verifying , analysis the feasibility of homogeneity temperature. The results of this experiment showed, after comparing for the inner induction heating and moving induction heating, the latter is more superior on homogeneity temperature of mold surface. The experimental data shows heating mold surface for 3 seconds by the inner induction heating would cause temperature difference of 80 degree Celsius, but using the moving induction heating could limit temperature difference below or between 10 degrees. In the case analysis of productions, the cases showed the moving induction heating made uniform surface temperature of mold, and then verified rough surface of productions by optical angle machine, which glossy rate is significantly lower and in line with expectations. They are all proof of the moving induction heating’s feasibilities.
