| Summary: | 碩士 === 國立臺北科技大學 === 製造科技研究所 === 106 === In this study, in order to solve the phenomenon that conformal cooling channels are fixed by using the hot spot method on the cavity side and the core side of the mold, resulting in uneven cooling of some areas of the product, the cavity side and the core side of the mold are designed with different cooling channel methods. Starting point, continuing the conformal cooling channels designed by the hotspot method, proposes a method of constructing conformal cooling channels by using thermal compensation, and deducing a thermal compensation formula that can obtain the optimal position of the other side of the conformal cooling channels by the heat energy taken away by one side of the conformal cooling channels, and the cooling analysis of the moldflow software proves that the conformal cooling channels established by one side using the hot spot method and the other side using the thermal compensation formula is more uniform than the conformal cooling channels using the same hot spot method on both sides.
This study uses Autodesk Simulation Moldflow 2016 to compare the conformal cooling channels built by the hotspot method on both sides and the conformal cooling channels built by the compensation method on one side, and verify the cooling effect for the two products - camera casing and fire helmet respectively. It is pointed out that the use of the compensation method can effectively solve the phenomenon of excessive cooling and make the product cooling more uniform.
