Molds or forms uses for manufacturing
Packerhead pipe require a certain amount of maintenance and care to insure
proper performance. There are three basic Packerhead mold designs:
Overhead Strip, Three-Piece, and Two-Piece Pull-Apart. Care and
maintenance functions are much the same for each type. OVERHEAD STRIP
Clean mold after each day’s
manufacturing by wiping the inner surfaces with a cloth, washing with
water, or sweeping with a broom. Clean the seams thoroughly using a small
trowel. Check the eccentric feet (Photo 1) and retractable pins (Photo 2).
If broken, bent or worn, they should be replaced or repaired.
The mold lock assemblies should also be
examined (Photo 3). The gates should lock without exerting an excessive
amount of force. Turn each adjusting bolt so the seam will close leaving
no play or looseness in the lock assembly.
THREE-PIECE
Clean mold and three seams using the
above methods. Inspect the pallet support blocks at the bottom of the mold
(Photo 4). If missing or worn replace with new blocks.
Replace the retractable pins if bent or
broken (Photo 2). Check and adjust the mold lock assemblies using the same
system as with Overhead Strip molds (Photo 5). Lubricate each grease
fitting located on the hinged seam assemblies (Photo 6).
The Adjustable Forklift Truck Adaptors
used in conjunction with Three-Piece Rack-Back molds are practically
maintenance-free. Necessary attention should be given, however, to the
lubrication of all fittings on the unit.
TWO-PIECE PULL-APART
Clean mold using same procedure as above.
When finished, check the latch adjustments (Photo 7). The latches should
lock without use of a "cheater" bar or pipe.
