Résumé : |
Bielefeld University of Applied Sciences has succeeded in developing an injection mold that does not require conventional liquid-based temperature control. Heat equalization is effected by means of heat pipes instead. Mold design and heat-pipe selection are based on the outcome of thermal simulations, which yield reliable results thanks to an unconventional approach. |
Note de contenu : |
- Ways to cool slim cores
- Problem solved by omitting media-based temperature control
- Successful simulation through the use of head pipe characteristic maps
- Characteristic map determination and in-house qualification
- New approach to simulating head flow in the mold
- FIGURES : 1. Conventional temperature control of cores is based on the use of heat-conducting inserts or the flow of liquid media - 2. Heat pipes exploit the temperature difference between heat source and heat sink
- 3. The capillary effect can be generated by different internal structures in the heat pipes - 4. Controlling the temperature of a core with a heat pipe - 5. No-cool mold for a cap application ; the heat pipes and removed core inserts are shown in the foreground - 6. Test rig for determining heat pipe characteristic maps. The temperatures at the two copper blocks are read with an infrared camera - 7. The characteristic map of a heat pipe shows the transferable heat capacity as a function of local temperatures |
