Abstract

An injection plastic mold is provided with its own on-board monitor or counter, which is actuated with each opening and closing cycle of the mold to maintain a count of the operating cycles performed. This count is maintained with the mold, whether the mold is on the press or a storage rack. The counter or monitor is relatively inexpensive and unobtrusive and is capable of withstanding harsh temperatures and shock that are encountered in an injection molding environment. The counter or stroke monitor may be either a mechanical counter or an electrical counter which is incorporated into a mold half to remain with the mold when it is stored away from a molding machine, when operated during an initial set-up operation, and when operated during a production run. Whether an on-board mechanical counter or an on-board electrical counter, the counter is hermetically sealed against the intrusion of damaging liquids or chemicals and is mounted in a protective housing to protect against shock, etc. An actuating mechanism is associated with the counter with the counter and its actuating mechanism secured to one of the mold halves so that the actuating mechanism causes the counter to advance and register a count with each molding cycle.
