Computer-based method for designing a mechanical part, especially the mold, runners and cooling channels for an injection molded plastic part, whereby the mold is decomposed into elementary slices and channel chambers

摘要

Computer-based method for designing a mechanical part, especially the mold, runners and cooling channels for an injection molded plastic part, involves the following steps: initial decomposition of the massive part into elementary slices (7i); fabrication of the elementary slices; and reconstruction of the whole part by superposition of the slices. The above stages incorporate similar steps for the elementary chambers (20) for the circulation of liquid coolant. The invention also relates to a corresponding mechanical part.
