| Summary: | 碩士 === 逢甲大學 === 機械與電腦輔助工程學系 === 105 === Produce a set of molds need to about 30 days, but life cycle of the product becomes shorter and shorter, the manufacturing schedule was also shortened. This research expect to use numerical simulation program to find the mold production situation when the mold design was completed, it can save the try and error.
This research used thermo-solid coupling because the heat effect is large. Form the analysis results, clamping force has a large effect on the plate, and the effect on the core is injection pressure and temperature. We add the gasket to improve the slide displacement, and we find add 10μm of gasket can improve about 0.1μm. We also found change the material parameters is a large impact on the analysis. It can be observed that some parts have stress concentration problems, it may cause the product failure because the part and part can not contact tight. If the problem can be found when we design the mold, it can save the time to fix.
