DME's external latch-lock system controls mold plate movements

June 2, 2021
The EZ-Latch system can be installed horizontally, allowing it to be used on mold plates as thin as 0.875 inch.

EZ-Latch DME’s external latch locks are used to control the movements of injection mold plates and are an alternative to more costly hydraulic cylinders often used for plate sequencing. External latch locks are appropriate for molds with three-plate sequencing, two-stage ejection and early-return systems. They come in a variety of lengths to cover a wide range of stroke requirements. A long latch bar version providing longer delayed ejection also is available. Standard sizes accommodate most mold base sizes and applications; DME also can provide custom sizes. 

What’s new? The EZ-Latch system and its patent-pending design. Unlike traditional external locks, which need to be vertically mounted, the EZ Latch lock can be installed horizontally, allowing it to be used on plates as thin as 0.875 inch.   

Benefits Long-lasting, more reliable functionality for plate sequencing. Competing devices use springs or friction devices to trigger the locking mechanism, which can make them prone to failure over time. The EZ-Latch system’s new design is stronger and ensures a safer, more reliable method of controlling mold plates. This can help avoid downtime and costly tool repairs. Also, the locks are easy to install, requiring no machining modifications.
