To Control Stripper Plate Cycle time is often wasted waiting for the press knock-out bar to function. With the application of the DME Jiffy Latch-Lok, as illustrated to the left, the stripper plate is moved in a secondary action of the mold opening without the aid of the press knock-out bar. The Jiffy Latch-Lok permits you to shorten the ejection stroke, improve cycle time and increase the number of parts per shift. To Float “X-1” Plate Away from “A” Plate while Locking “X-1” and “B” Plates In this application of the Jiffy Latch-Lok, the “X-1” plate is floated away from the “A” plate in the first mold opening sequence. At a predetermined opening (you determine the distance) the “X-1” plate is released from the “B” plate for the second mold opening. This application of the Jiffy Latch- Lok is particularly effective on “AX” or three-plate top runner molds. To Float “A” Plate Away from Top Clamp Plate while Locking “A” and “B” Plates In the DME Latch-Lok application illustrated here, the “A” plate moves away from the top clamp plate in the first mold opening. During this portion of the cycle, the “A” and “B” plates are locked. As the release bar passes the rocker, the “A” and “B” plates part in the second mold opening. Actuation of Ejector Assembly Without Aid of Press Knock-Out Bar (LL151 only) For those mold applications where a shorter press stroke is required, the DME Jiffy Latch-Lok is extremely effective. You can activate the Jiffy Latch-Lok at any time after the mold begins to open, and pull the ejector assembly forward. This simple action shortens cycle time and increases part production. Can also be used for “Reverse” Ejection from the Stationary Side of the Mold.
