About Ejector Pins
Use an ejector pin to push the cold plastic part out of the cavity insert when the mold base is opened.
The placement of the ejector pins can be specified using datum points in the reference model.
If no reference model exists, the placement references for ejector pins can be defined in the core model of the Creo Expert Moldbase assembly.
