Thermal Analysis and Optimization of Conformal Cooling Channels in Injection Moulding Machine to Reduce Cycle Time

Abstract

The cooling properties of an injection mould are significantly influenced by the design and kind of cooling channel used. Specifically, the present study seeks to determine the impact of various design parameters of the cooling channel on the performance of an injection mould. The cooling channel diameter and cooling channel pitch are the optimization factors to be considered. The CAD model is subjected to thermal analysis in the ANSYS programme under transient circumstances. When the coil dia and pitch of the cooling channel are varied, the design points are created automatically. A study is conducted to determine the influence of various design elements on directional and total heat fluxes. It was discovered that both of the design factors had a statistically significant impact on the heat absorption properties of the cooling channel under investigation. In order to determine how much of an influence coil dia has on total heat flux and total heat flux, sensitivity plots were constructed. It is possible to gain a roughly 11.3 percent boost in cooling efficiency by using optimization techniques.
