Conformal Cooling Channels

Cooling channel design is important in mould designs to achieve shorter cycles, dimensional stability and reduced part stresses. Traditionally, cooling channels have been machined into mould components to avoid interference with the ejection system, coring, cavity and other mould details. Over the years straight drilled cooling channels have given away, in part, to conformal cooling technique often using free form fabrication techniques. This paper presents a study of optimised mould design with conformal cooling channel using finite element analysis. Various configurations of conformal cooling channels have been developed. The part cooling time using the conformal cooling channels and the straight cooling channels in the mould are computed using the Pro/Mechanica Thermal FEA software. Results are presented based on temperature distribution and cooling time using steady state and transient analysis conditions. The results show a reduction in cycle time for the plastic part with conformal cooling channel design.

This study presents a multiphysics simulation analysis that was performed for the cooling channel of a built-in spindle. The design of experiments (DOE) method was employed to optimize the dimension of the cooling channel, and a practical machining experiment was performed to validate the effect of the design. In terms of the temperature, pressure drop, thermal deformation, manufacturing cost, and initial cost considerations, the paralleling type cooling channel of the front bearing and the helical type cooling channel of the motor were adopted in the study. After the optimal design of the cooling channel was applied, the bearing temperature was reduced by a maximum decrease of 6.7 °C, the spindle deformation decreased from 53.8 μm to 30.9 μm, and the required operational time for attaining the steady state of the machine tool was shortened from 185.3 min to 132.6 min. For the machining validation, the spindle with the optimal cooling channel design was employed for vehicle part machining, the flatness of the finished workpiece was increased by 61.3%, and the surface roughness (Ra) was increased by 52%. According to the findings for the optimal cooling channel, when the spindle cooling efficiency is increased by the optimal cooling channel design, the thermal deformation and warm-up period can be reduced effectively, and the machining precision can be enhanced. This method is an efficient way to increase the accuracy of a machine tool.
