Do Lock (mold opening/closing control device)

●Do Lock – The original mold opening/closing control device, patent pending (as of November 1, 2022)

　・Both mold opening and closing can be controlled.
　・Failure risk reduced due to simple design with a single inner part (slide lock).
　・Production cost reduced by sharing parts with Yuki Lock 100N/W.

Operation check of Do Lock

●Operating check of Do Lock

①Mold closed state  A parting device is locked even when the movable platen moves.
②Slide lock starts moving to the release bar socket.
③Slide lock moves into the release bar socket, and a parting device is released.
④As mold closes, Ⓐ clearance between the platens is retained by slide lock and release bar;

Various Super Locks (mold opening control devices)

●Features of Super Lock (mold opening control device)

　・Exceptional stability of mold opening/closing due to combination of disk springs and outer/inner twin rollers
　・Due to vertically symmetrical design of lock bushes, reuse by reverse is possible when one side is worn out
　・Strength of right and left rollers can be easily changed with adjusting bolts
　・Galling and other problems reduced due to the lock guide provided with back relief

Super Lock's durability specifications

●Super Lock: durable design

　・Durability was improved about 5-fold as compared to other manufacturers.
　・Wear resistance was achieved by revising material and heat treatment of lock bushes.
　・Due to smaller purchase of consumables and less frequent part replacement, costs can be cut, and production losses can be turned to productivity gains.

Durable design

● Features of Yuki Lock (mold opening control device)

　・Newly developed release bar adopted instead of previous spring-dependent mechanism
　・Mechanical stability made possible due to special shape of release bar, slide lock and cam lock
　・Improvement of productivity by avoiding a risk of parts damage in unlocking
