PLASTIC & INJECTION MOLDING

Zero mold modification KO bar quick connect/disconnect system

HYDRA-LATCH™
Quick Knock Out System

A Quick Mold Change system is not complete without an efficient means of connecting and disconnecting Knockout Bars (KO Bars). The Hydra-Latch™ KO System is it! Hydra-Latch™ is durable, compact, innovative and fits practically every machine. No mold modification required. An important reason for choosing Hydra-Latch™ is its easy installation and flexibility. It can fit between tie bars, avoid interference from KO plate push/pull pistons and can be installed without loss of ejection stroke*. Existing KO Bars are utilized after being shortened, drilled and tapped to accommodate the Hydra-Latch™ Receivers.
*Does not apply to front mounted manifolds.

A. Machined and hardened retainers which, when elevated, secure the receiver. Hydraulic pressure is used to recess retainers allowing the probe and receiver to separate.
B. Hydra-Latch™ probe incorporates a mechanism which prevents separation of probe and receiver until hydraulic pressure is applied.­
C. Exclusive pilot allows retainers to elevate only when properly engaged with the receiver thus ensuring positive coupling.
D. Hydra-Latch™ receiver incorporates internal groove to secure elevated retainers. Receivers are secured to KO‑Bars which have been shortened 3" (mini) or 6.5" (maxi). See chart.
E. In the absence of hydraulic pressure the receiver and probe may be separated mechanically.
