ABSTRACT:
A die casting die particularly adapted for casting of parts with protruding heat sink pins. The die ejector half insert is made of two distinct pieces. One piece, the ejector cavity insert, includes through holes which define the heat sink pin-forming cavities. These cavities are closed by a combination of the second piece of the ejector half insert, and the ejector pins. The result is a more uniform part with less flashing, which ejects easily from the die. There is also less die wear associated with the ejector pins.
