METHOD OF INSTALLING THE PARTING LOCK SET/EXAMPLE OF PLSW OPERATION

Form bolt holes and reamer holes in the mold parallel to the PL face to a pitch accuracy of within ±0.01. If the pitch accuracy is within ±0.02, form the holes to the reamer pilot hole dimension. (Machine the holes while taking into consideration the clearance between the insert and the mold.)	Install the cam holder on the movable mold.	In order to eliminate looseness between the cam lock and the slide lock, insert the release bar, temporarily fix the slide holder while pulling it parallel to the cam holder, ream the holes and press-fit the dowel pins. In this condition, confirm that the release bar operates smoothly, and then tighten the slide holder with the bolts.	Install the die in the molding machine, cut the release bar to the necessary length, form the bolt holes and reamer pilot holes, temporarily fix the release bar, check the sliding operation of the parting lock, and then ream the holes and press-fit the dowel pins.Make the overhang length r of each release bar the same in order to equalize the timing of the release.

1)Form bolt holes and reamer holes using NC machining, and install the cam holder parallel to the PL face.
2)Cut the cam lock to the necessary length, form 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, form the dowel holes, and fix the cam lock.
3)Cut the release bar to the necessary length, and install it perpendicular to the mold. Make the overhang length R of each release bar the same in order to equalize the release points.
