Gibraltar EY6499-G Die Mold Ejector Sleeve 9/16 X 3/4 X 7 in

Product Description

The GIBRALTAR EY6499-G is a nitride coated die steel ejector sleeve designed for use in die mold tooling applications. The sleeve features a 9/16 inch inside diameter, a 3/4 inch outside diameter, and a 7 inch overall length. The head measures 1 inch in diameter with a 1/4 inch head height. A 45-degree chamfer at 3/64 inch chamfer length and a 1/32 inch corner radius provide controlled part ejection geometry. The nitride coating increases surface hardness and wear resistance, extending service life in high-cycle molding operations. This component is typically installed by tool and die makers or mold maintenance technicians.

The EY6499-G ejector sleeve is used in injection mold, die cast, and compression mold tooling where a hollow ejector pin is required to eject parts formed around a core pin. It is suited for tight-tolerance mold bases in both production and prototype tooling. The sleeve accepts a corresponding core pin through its bore and works in conjunction with the ejector plate assembly to push finished parts clear of the mold cavity at end of cycle.

Key Features

• 9/16 inch inside diameter and 3/4 inch outside diameter for precise fitment in standard mold bases
• 7 inch overall length accommodates deeper mold stack configurations
• Nitride coated die steel construction for enhanced surface hardness and extended wear life
• 1 inch head diameter with 1/4 inch head height for positive retention in ejector plate
• 45-degree chamfer at 3/64 inch length and 1/32 inch corner radius for controlled ejection geometry

Compatibility

Designed as an OEM-style replacement or direct tooling component for die mold ejector sleeve applications requiring a 9/16 inch ID by 3/4 inch OD sleeve with a 7 inch overall length and standard 1 inch head diameter.

Installation Notes

Installation is performed by qualified tool and die makers or mold technicians. The mold must be fully de-energized, cooled, and depressurized before disassembly of the ejector plate assembly. Verify bore alignment between the ejector plate and mold cavity insert before seating the sleeve to prevent galling or binding. Follow the mold manufacturer's assembly procedures and applicable shop safety protocols when handling precision ground tooling components.
