PARTING LOCK SETS –MOLD OPENING/MOLD CLOSING CONTROL TYPE–

■ Characteristics • Mold closing control (closing PL surface after closing the stripper plate, etc.), which was not possible with the conventional parting lock set (PLS/PLSW), is now possible.

• The lock bar is long, so it can also be used for thrusting out the stripper plate. • Enables accurate mold opening and closing movement with no reaction.

■ How to mount (1)Mount 2 or more parting lock sets at symmetrical positions of the mold. PLSZ: 10kN or less for 1 mold/when mounting 2 sets PLMZ: 20kN or less for 1 mold/when mounting 2 sets (2) Make bolt holes and reamer holes using NC machining, and install the cam holder parallel to the PL face. (3) Cut the lock bar to the necessary length, make the bolt holes and reamer pilot holes, tighten the cam lock with the bolts while pulling it, carry out position adjustment by matching with the actual part, make the dowel holes, and fix the cam lock. (4) Cut the release bar to the necessary length, and install it perpendicularly to the mold. Make the overhang length ℓ of each release bar the same in order to equalize the release points. (Maintain proper alignment of the release points to avoid uneven contact and resultant breakage).
