Abstract
The article deals with the issue of manufacturing conformal cooling channels to ensure efficient cooling of composite metal-metalpolymer molds. A brief description of both the design of the composite mold and the technology for its production is given. Conformal cooling channels in the composite mold are made in the metal-polymer part, which reduces the distance from the surface of the cooling channel to the cooled forming surface. Experimental studies are given on the example of a composite mold for the "collar" part. Fixing the temperature data of heating and cooling of the metal-polymer molding is carried out using a thermal imager. Evaluation of the results of the study show the efficiency of manufacturing conformal cooling channels directly in the metal-polymer part of the mold. An analysis of the experimental results allows numerically evaluating the cooling efficiency and comparing it with the cooling of a composite mold, in which the cooling channels are made in a metal cage. An assessment of the efficiency of using a composite mold with cooling channels made in the metal-polymer part in the context of saving the main technological time for the production of a batch of parts is given. In conclusion, the difficulties that arose in the process of manufacturing conformal cooling channels in the metal-polymer part and the tasks that require further research in the technology of manufacturing composite molds are described.
