Influence of Cooling Channel Position and Form on Polymer Solidification and Temperature in Injection Molding Die
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
This investigation focuses on the temperature distribution in injection molding component and die, which plays a major role in cooling time and quality of the part. When the molten plastic enters the mold, it cools down and solidifies by dispatching its heat through cooling channels. To study the influence of cooling channel position and forms, a full two dimensional transient type of analysis carried out using ANSYS. For higher productivity and product quality, mold cycle time should be minimized and at the same time, uniform cooling of component should be necessary to avoid thermal residual stresses. An optimized position and form of cooling channel is determined, leads to uniform distribution of temperature with minimized mold cycle time. This study also, shows the comparison between results of positional cooling channels and conformal cooling for die. The results obtained from conformal cooling system design highly minimize the cooling time and it fails to achieve homogeneous cooling throughout the mold.
