Assembly and Installation Guidelines
• At end of second stroke, Body for Cam Fingers must seat firmly against Center Rod head or spacer plate. • The moldmaker must cut and/or grind the Center Rod to the required length prior to installation of the 2-Stage Ejector assembly into the mold base. The recommended tolerance on the Center Rod length after the customer has cut the Center Rod is +0/-0.02mm or less. • The moldmaker must cut and/or grind the Travel Sleeve to the required length prior to installation of the 2-Stage Ejector assembly into the mold base. • Stroke 1 (H1) is reduced by cutting and/or grinding the moving platen end of the Center Rod. • Stroke 2 (H2) is reduced by cutting and/or grinding the moving platen end of both the Center Rod and the Travel Sleeve. • All 2-Stage Ejectors in a mold must be cut to the same strokes. • It is recommended that guided ejection be used. • Ejector speed must be controlled, ensuring that excessive shock loading does not occur. • 2-Stage Ejectors are not suitable for severe load conditions. • 2-Stage Ejectors must not be exposed to temperatures that exceed 150 ° C (300 ° F) at any time. • Lubricate all metal-to-metal contact areas initially and periodically as required. A good grade of moldmakers non-melting type grease for the appropriate temperature should be used. • A minimum of (4) Puller Pins should be used with each mold. Larger molds may require additional Puller Pins. • The moldmaker must cut and/or grind the Puller Pins to the required length. • Puller Pins are not included with Bottom Last Assemblies and must be ordered separately.
