| Résumé : |
The striving for injection molded parts with an increasing functional density leads to more complex molds, which are more and more designed with injection molding simulation. Nowadays, software allows the operator to analyse not only the filling stage, but also the thermal activity within both, the mold and the part during the whole process cycle. However, commercial simulation software for injection molding does not offer the visualisation of the flow of the temperature control medium to get a reliable determination of the pressure drop and the local heat transfer coefficients (HTC). For this reason the potential of an exact implementation of the local HTC „towards the temperature control medium, for improving the prediction precision of the thermal design, has been analysed at the Institute of Plastics Processing (IKV), Aachen. In order to use prior calculated HTCs from Computational Fluids „Dynamics (CFD) simulations inside injection molding simulations, the development of an analogous model was required. An isolation layer between cooling channel and mold was therefore introduced, which allows to set a local heat transfer by varying the geometric dimensions of the layer. Several cooling channel layouts, which differ in geometric aspects (e.g. bends, diameter or fragmentation/consolidation of parallel channels) were studied with this set-up. |
