Gibraltar LEP2146-G Straight Ejector Pin 9/16 in Steel

Product Description

The GIBRALTAR LEP2146-G is a straight ejector pin used in injection mold tooling to push finished parts out of a mold cavity at the end of a molding cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 9/16 inch in diameter with an overall length of 18 inches and a usable pin length of 17.75 inches. The head diameter is 13/16 inch with a head height of 1/4 inch. Mold makers and tooling technicians rely on this style of pin for consistent ejection force and dimensional stability across high-cycle production runs.

This ejector pin is suited for use in plastic injection molds, die casting tooling, and similar mold base applications where a standard straight ejector pin profile is required. It is typically installed in the ejector plate assembly of a mold and driven by the ejector system of the molding press. The nitride surface treatment extends service life in abrasive or high-temperature molding environments. Sized for applications requiring a 9/16 inch pin diameter, it fits mold bases designed to that bore specification.

• Sold individually — minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or new-build component for injection mold tooling and mold base assemblies requiring a straight ejector pin with a 9/16 inch pin diameter and 18 inch overall length.

Installation Notes

Ejector pins are installed and serviced by mold makers or tooling technicians. Power down and de-energize the molding press and relieve any hydraulic or pneumatic pressure before accessing the ejector assembly. Pins should be installed with the head properly seated in the ejector plate counterbore and aligned parallel to the mold parting direction to prevent side-loading and premature wear. Follow the mold base manufacturer specifications for pin fit and clearance tolerances.
