Exact Tolerance 1.2379 Die Steel Nitriding Ejector Pin For Home Appliance Injection

Ejector pins serve as the ejection mechanism in injection molding processes, applying force to release finished parts from molds. These precision components extend into mold cavities after opening, push the molded product out, then retract to allow mold closure and refilling.

Part ejection represents the final step in plastic injection molding, with ejection quality directly impacting the final product quality. During mold opening, plastic products must remain on the core half, where the ejector mechanism facilitates release.

• Balanced Ejection Force: Layout should distribute ejection force evenly. Complex structures require additional ejector pins due to higher demolding forces.
• Strategic Placement: Position ejector pins at effective locations including ribs, columns, steps, metal inserts, and complex structural areas. Maintain symmetrical arrangement around ribs and columns.
• Surface Considerations: Avoid placement on inclined surfaces or oversteps. Position on smooth surfaces within well-supported structural areas.
• Flat Ejector Applications: Utilize flat ejector pins for deep ribs (≥20mm depth) or where dome pins are impractical. Consider insert forms for easier processing.
• Structural Integrity: Avoid placement near sharp or thin steel sections. Ensure ejector pin top surfaces don't contact cavity sides.
• Cooling System Coordination: Maintain proper distance between ejector pins and water channels to prevent processing interference and water leakage.
• Exhaust Function: Position in areas prone to vacuum formation during ejection, such as large cavity planes where vacuum can increase demolding force.
• Restricted Areas: Avoid appearance surfaces on cosmetic parts and light-transmission areas on transparent plastic components.
