3D PRINTED INJECTION MOLD TOOL WITH IMPROVED HEAT TRANSFER AND MECHANICAL STRENGTH

机译:具有改进的传热和机械强度的3D打印注射模具

摘要

A problem exists of prohibitively high costs associated with molds for small run, legacy, or prototype injection molded parts. Further, the lead time on molds is currently on the order of about two weeks. A mold is provided that is formed from three-dimensional printing. The mold includes a series of air and/or water cooling channels to limit thermal stresses to the mold. Additionally, a series of coatings is added to the surface of a 3D printed mold to extend the lifetime of the mold and increase the performance of the mold. The coatings perform a function other than to define a shape of an injection cavity, such as improving thermal conductivity, providing a thermal barrier between the injection material and the mold body, or improving the detachment of the final mold product from the mold body.
