Gibraltar EY6479-G Die Mold Ejector Sleeve 5/8in Od

Product Description

The GIBRALTAR EY6479-G is a nitride coated die steel ejector sleeve designed for use in die mold tooling applications. With a 7/16 inch inside diameter and a 5/8 inch outside diameter, this sleeve provides a precision fit for ejector pin assemblies. The overall length is 5 inches, and the head diameter measures 7/8 inch with a 1/4 inch head height. A 45-degree chamfer angle and 3/64 inch chamfer length facilitate smooth ejection strokes, while a 1/32 inch corner radius reduces stress concentration. The nitride coating improves surface hardness and wear resistance for extended service life in high-cycle mold environments. Toolmakers and mold technicians are the primary installers.

This ejector sleeve is suited for injection mold, die cast, and compression mold tooling setups where round-core ejection is required. It is intended for use in applications where a standard sleeve ejector configuration is specified. The part is sold individually and is appropriate for both production tooling and maintenance replacement scenarios in industrial mold shops.

Key Features

• 7/16 inch inside diameter and 5/8 inch outside diameter for precise ejector pin clearance
• 5 inch overall length suits standard ejector plate stack heights
• Nitride coating enhances surface hardness and extends wear life in high-cycle applications
• Die steel construction provides strength and dimensional stability under mold pressure
• 45-degree chamfer angle with 3/64 inch chamfer length for smooth ejection entry
• 7/8 inch head diameter and 1/4 inch head height for positive retention in ejector plates

Compatibility

Designed as an OEM-style replacement or direct tooling component for die mold ejector sleeve applications requiring a 7/16 inch inside diameter, 5/8 inch outside diameter, and 5 inch overall length in nitride coated die steel construction.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians. Before servicing or replacing ejector components, ensure the press is locked out and all hydraulic and pneumatic pressure is fully relieved. Inspect the ejector plate bore and mating pin for wear or galling before installing the new sleeve. Follow applicable shop safety standards and mold maintenance procedures when handling hardened tooling components.
