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.
