Abstract (en)
Invention relates to a piston for die casting comprising a piston body, which is a single-element object, and a thermal regulation system integrated into or built inside the piston body, wherein thermal regulation system includes a passageway enabling flow of fluid for temperature regulation of the piston. There are no limitations on the passageway spatial position within physical boundaries of the piston body. Innovative solution enables optimization of the piston cooling effectiveness throughout the casting cycle. The proposed piston with integrated cooling is generally produced as a single-element product utilizing a particular manufacturing technology. Based on the piston design simplicity the invention also assures its cost-effective production.
