Gibraltar EY6505-G Die Mold Ejector Sleeve Nitride Steel

Product Description

The GIBRALTAR EY6505-G is a die mold ejector sleeve machined from nitride coated die steel for use in injection mold and die casting tooling applications. The sleeve features a 0.625 inch inside diameter and a 0.875 inch outside diameter, with an overall length of 4 inches. The head measures 1.125 inches in diameter and 0.25 inches in height. A 45-degree chamfer with a 0.047 inch chamfer length and a 0.031 inch corner radius allows for controlled part ejection and smooth sleeve seating. This component is installed by moldmakers and tooling technicians during mold assembly or rebuild operations.

Ejector sleeves are used in plastic injection molds and die casting dies where cylindrical or tubular part features require positive ejection from the cavity. The EY6505-G fits into standard ejector sleeve retainer plates and works in conjunction with a corresponding ejector pin running through the sleeve bore. It is suited for production tooling in both prototype and high-volume manufacturing environments where consistent ejection force and dimensional stability are required.

Key Features

• Nitride coated die steel construction for improved surface hardness and wear resistance
• 0.625 inch inside diameter accommodates matching ejector pin sizing
• 0.875 inch outside diameter for standard sleeve bore fitment
• 4 inch overall length suits common mold base plate stack heights
• 1.125 inch head diameter with 0.25 inch head height for positive retainer plate seating
• 45-degree chamfer angle with 0.031 inch corner radius for smooth entry and reduced stress concentration

Compatibility

Designed as an OEM-style replacement or new-build component for standard ejector sleeve retainer plate configurations in injection mold and die casting tooling assemblies.

Installation Notes

Installation is performed by qualified moldmakers or tooling technicians. The mold should be fully de-energized, cooled, and depressurized before disassembly of any ejector plate components. Verify bore alignment and clearance tolerances between the sleeve outside diameter and the retainer plate bore before pressing the sleeve into position. Do not force the sleeve into an undersized bore, as this can cause cracking or dimensional distortion of the nitride coating.
