ABSTRACT:
There is disclosed herein an improved reciprocating device for use with various forming machinery such as die casting, molding or other like equipment. The reciprocating device is adapted to advance a spray head across the working surfaces of a die, mold or other like forming apparatus when such apparatus is in an open position thereby allowing the spray head to spray these surfaces with a combination of fluids, such as air and/or lubricants, for example. The apparatus employs a spray head having a plurality of nozzles, which is secured to one end of an elongated arm. The opposite end of this elongated arm is removably secured to a carriage assembly which is caused to reciprocate through the cooperation of a threaded rod and drive motor means, thereby alternately extending and withdrawing the elongated arm. Limit switches are provided which are actuated by engagement with portions of the carriage assembly thereby providing means for controlling the flow of fluids to the spray head, the drive motor means and otherwise controlling the operational cycle of the reciprocating device. Additionally, a disc brake means is provided to prevent rotation of the threaded rod when in an on position thereby preventing undesired movement of the carriage assembly, elongated arm, and associated spray head. Various limit switches, timers, valving arrangements, and other control apparatus may be included to provide a wide variety of operational cycles.
