Gibraltar EY6463-G Die Mold Ejector Sleeve 5/16 Id 7/16 Od

Product Description

The GIBRALTAR EY6463-G is a die mold ejector sleeve designed for use in injection mold tooling and die casting applications. It features a 5/16 inch inside diameter and a 7/16 inch outside diameter, with an overall length of 7 inches. Constructed from nitride coated die steel, this sleeve provides a hardened, wear-resistant surface that extends service life under repeated ejection cycles. The 11/16 inch head diameter and 1/4 inch head height seat securely in standard ejector retainer plates. A 45-degree chamfer angle with a 3/64 inch chamfer length and a 1/32 inch corner radius complete the geometry. This component is installed by toolmakers and mold maintenance technicians during mold build or repair.

This ejector sleeve is suited for precision mold tooling in both production and maintenance environments. It is used wherever a tubular ejector element is required to strip a molded part from a core pin in injection molds or die casting tools. The nitride coating makes it appropriate for moderate- to high-volume production molds where surface wear and galling resistance are priorities. Toolrooms handling plastic injection molds or die casting dies represent the primary installation context.

Key Features

• 5/16 inch inside diameter and 7/16 inch outside diameter for precise core pin clearance
• 7 inch overall length accommodates standard mold base ejector plate spacing
• Nitride coated die steel construction for improved surface hardness and wear resistance
• 11/16 inch head diameter with 1/4 inch head height for positive retention in ejector retainer plates
• 45-degree chamfer angle with 3/64 inch chamfer length and 1/32 inch corner radius for controlled part contact

Compatibility

Designed as an OEM-style replacement ejector sleeve for standard die mold tooling applications requiring a 5/16 inch ID tubular ejector component.

Installation Notes

Installation is performed by qualified toolmakers or mold maintenance technicians. The mold must be fully de-energized, cooled, and removed from the press before ejector components are serviced. Verify that the replacement sleeve seats fully and moves freely within the ejector retainer plate before reassembling the mold. Do not force the sleeve into a misaligned bore, as this can cause galling or cracking of the nitrided surface.
