Through Hardened Ejector Pins – Actuation

After the mold closes, the part cavity is filled by the sprue and runner system. When the part has cooled the mold opens and sprue puller pin separates the sprue from the injection nozzle. The ejector plate then makes contact with the machine ejector rod that forces the ejector pins forward, ejecting the part and its runner system. When the mold closes, return pins force the ejector system back.
