  • Publication number: 20080060780
    Abstract: A method for operating an automated reciprocator for applying lubricant in a die casting system. As a reciprocator is moved between two die halves and a fluid is applied to the dies with the reciprocator, a safety bar is moved ahead of the reciprocator. Any objects in the path of the reciprocator are detected by contact with the safety bar. If the safety bar contacts an object as the reciprocator is moving down, a sensor signals a control system and the reciprocator is stopped.

  • Publication number: 20060005938
    Abstract: An automated reciprocator for applying lubricant to the cavity of a die casting system having a safety bar for preventing the reciprocator from injuring a person or damaging equipment which may be present in the reciprocator travel path. The safety bar is movably carried on the lower side of the reciprocator and includes a sensor to detect relative movement between the safety bar and the reciprocator. The proximity sensor is coupled to a control system. If the safety bar contacts an object as the reciprocator is moving down, the sensor signals the control system and the reciprocator is stopped.
