IMPROVE COOLING EFFICIENCY OF INJECTION MOLDING BY PULSED-COOLING APPROACH

摘要

Recently, the variotherm molding technologies are more and more popular, and among them, pulsed cooling approach is a more practical one. In general, the pulsed cooling approach is used for the mold temperature control without changing cooling system design. However, it is very complicated to apply pulsed cooling approach due to the special cooling control and transient behavior of the mold. Hence, how to optimize this technology is the major concern. In this study, through applying the comprehensive consideration with various operation specifications in simulation method, including pulsed time, coolant temperature, mold open and mold close temperatures, the cycle time can be dramatically reduced comparing to that of conventional method. In addition, experimental study will also perform to verify and realize the core issues to compare with simulation in the coming future.
