ABSTRACT:
The plastic injection molds are essential in the product dimensional quality, and to achieve the best performance of them in their product lifecycle, it is a fundamental task that will maximize the profitability and investment in the design, manufacture of the injection molds. One of the important factors in the performance of the mold lies in the temperatures to which it is exposed and temperature gradients could generate thermal fatigue wear, a common problem in injection molds. The present study shows an analysis and simulation through finite volume method (VF) of the temperature distribution in a mold injection for plastics and their respective validation through complete 2k factorial design for an area included in the mold cavities. Respect to the studied processing variables is found which cooling temperature has a high relation in the final mold temperature distributions and specifically for value of 45°C in addition to cooling times an packing times in his higher levels (17 and 3 seconds respectively) contributes with homogenous mold distribution .
