| Abstract: |
| Injection moulding plays an important role in the production of plastics and the cooling performance of injection moulds affects the productivity as well as quality of plastic products as well as product quality. This paper investigates the topology optimisation of the cooling system for injection moulds based on the density-based topology optimisation approach with the objective of minimising the average temperature of the structure. As the mould is subjected to a large clamping force applied by the injection moulding machine to overcome the expansion force of the moulded part during the injection moulding process, the structural load-bearing performance of the mould is also used as a constraint function. Based on the open source platform OpenFOAM, this 3D flow-thermal-mechanical coupled topology optimisation problem is solved and a manufacturing-feasible cooling system design is obtained. |
