Product catalog summary
Overview
The QMC 400 ejector coupling is designed to enhance productivity in the plastic industry by facilitating quick and safe connections of ejectors. It significantly reduces mould change time, contributing to overall setup time optimization.

Assembly
The coupling is fastened to the ejector piston rod, and the bolt is secured in the ejector package of the moulds. This setup allows for seamless integration into machine control systems, enabling fully automatic mould changes within minutes.

Machine Safety
  • Proximity switches indicate 'Coupling opened', 'Coupling closed', and optionally 'Ejector bolt present', which is mandatory for fully automatic mould changes.

Operating Principle
  • No energy supply is required during operation.
  • Coupling closes through spring force, with hydraulic or pneumatic activation options.
  • Two variants are available, with and without axial stroke for coupling.

Technical Data
  • Max pressure force: 125 kN (QMC 400.125) and 500 kN (QMC 400.500).
  • Max tensile force: 63 kN (QMC 400.125) and 250 kN (QMC 400.500).
  • Radial position tolerance: ±1 mm (QMC 400.125) and ±2 mm (QMC 400.500).
  • Axial coupling tolerance: 0 - 0.1 mm.
  • Hydraulic release pressure: 2.4 - 16 MPa (24 - 160 bar).
  • Pneumatic release pressure: 2 MPa (20 bar).

Options and Accessories
  • Mould side and machine side adapters available on request.
  • Proximity switch for 'Mould ready and available for coupling'.
  • External hydraulic unit and pressure converter with directional valve.

Proximity Switch Query
  • Operating voltage: 24 V DC.
  • Output function: PNP, NO contacts.
  • Protection class: IP 67.
  • Max ambient temperature: -25 to +70 °C.

Conclusion
The QMC 400 ejector coupling offers a robust solution for quick mould changes, enhancing efficiency and safety in the plastic industry. Its integration capabilities and technical specifications make it suitable for various machine types and applications.
