Abstract

In this study, an experimental research
has been carried out for the production of plastic injection molds with
conformal cooling channels by laminated brazing. In order to increase the
efficiency of the cooling system, conformal cooling channels are designed. Mold
cores and cavities were cut into layers and machined into plates. The plates
are combined with vacuum brazing method to produce plastic injection mold with conformal
cooling channels. The production of plastic parts was tried with two molds with
conformal and straight cooling channels. According to the results, both the
cycle time and the preparation time of the plastic injection mold for
production were shortened by the use of conformal cooling channels.
