Gibraltar EY6486-G Die Mold Ejector Sleeve 7/16x5/8 in

Product Description

The GIBRALTAR EY6486-G is a nitride coated die steel ejector sleeve designed for use in die mold tooling applications. With a body inside diameter of 7/16 inches and a body outside diameter of 5/8 inches, the sleeve delivers a precise fit within mold assemblies. The overall length is 12 inches, making it suitable for standard ejector plate setups. Nitride coating improves surface hardness and wear resistance, extending service life under the high-cycle conditions typical of production tooling. This sleeve is installed by toolmakers and mold technicians working in injection mold and die casting operations.

The EY6486-G is used in die mold assemblies where controlled ejection of molded parts is required. The 7/8 inch head diameter and 1/4 inch head height seat securely in ejector retainer plates. A 45-degree chamfer angle with a 3/64 inch chamfer length and 1/32 inch corner radius ensures smooth seating and reduces stress concentration at the head transition. This sleeve suits both prototype and production mold builds requiring tight dimensional tolerances on ejector components.

Key Features

• Nitride coated die steel construction for enhanced surface hardness and wear resistance
• 7/16 inches inside diameter x 5/8 inches outside diameter body for precise bore fit
• 12 inches overall length accommodates standard ejector plate configurations
• 7/8 inches head diameter with 1/4 inches head height for secure retainer plate seating
• 45-degree chamfer angle with 3/64 inches chamfer length reduces stress at head transition
• 1/32 inches corner radius for smooth ejector plate engagement

Compatibility

Designed as an OEM-style replacement or direct tooling component for die mold ejector systems requiring a 7/16 inches ID x 5/8 inches OD sleeve with a 12 inches overall length.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians. The mold and all associated machinery must be fully de-energized and locked out before ejector plate disassembly or sleeve replacement. Verify bore alignment and retainer plate clearances before seating the sleeve to avoid galling or misalignment during operation. Follow applicable shop safety and tooling standards for press and mold maintenance procedures.
