Gibraltar EY6477-G Die Mold Ejector Sleeve 3/8 Id 1/2 Od

Product Description

The GIBRALTAR EY6477-G is a die mold ejector sleeve designed for use in injection mold tooling and die casting applications. Manufactured from nitride coated die steel, this sleeve delivers hard surface wear resistance while maintaining toughness in the core. It measures 0.375 inches inside diameter, 0.5 inches outside diameter, and 12 inches overall length. The head diameter is 0.75 inches with a head height of 0.25 inches. A 45-degree chamfer angle and 3/64-inch chamfer length facilitate smooth part ejection. The 1/32-inch corner radius reduces stress concentration at the head transition. This component is installed and serviced by mold makers, toolmakers, and die maintenance technicians working in precision manufacturing environments.

The EY6477-G ejector sleeve fits into standard mold bases where a hollow ejector pin is required to eject tubular or cored features from a mold cavity. It is suited for high-cycle production tooling in plastic injection molding and die casting operations. The nitride coating extends service life in abrasive or high-temperature ejection cycles. This sleeve is a direct fit for mold builds and tooling repair jobs requiring a 0.375-inch bore with a 0.5-inch outer body diameter and 12-inch active length.

Key Features

• Nitride coated die steel construction for hard surface wear resistance
• 0.375 inches inside diameter and 0.5 inches outside diameter body dimensions
• 12 inches overall length for deep-draw or extended ejection stroke applications
• 0.75-inch head diameter with 0.25-inch head height for positive retention in the ejector plate
• 45-degree chamfer angle with 3/64-inch chamfer length for smooth mold entry and ejection
• 1/32-inch corner radius at head transition to reduce stress concentration

Compatibility

Designed as a standard-dimension replacement or new-build ejector sleeve for die mold tooling requiring a 0.375-inch inside diameter, 0.5-inch outside diameter body, and 12-inch overall length configuration.

Installation Notes

Ejector sleeves are installed and replaced by qualified mold makers or toolroom technicians. Always fully de-energize and lock out the press or molding machine before accessing the mold base or ejector assembly. Verify bore alignment and clearance fits before pressing the sleeve into the ejector retainer plate. Follow the mold manufacturer's dimensional tolerances and surface finish requirements when seating this component.
