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.
Claims9
A die casting system, comprising:
- an automated reciprocator adapted for moving between two die halves and applying a fluid to the dies,
- a safety bar carried on the reciprocator, the bar positioned to move ahead of the reciprocator, and
- a sensor for providing a signal when the safety bar contacts another object wherein the system further comprising a slidable connector supporting the safety bar from a lower surface of the reciprocator, the connector limiting the maximum distance between the safety bar and the reciprocator, but allowing the safety bar to move toward the reciprocator.
