MOLD CHANGE WITH OR WITHOUT HEIGHT CHANGE STEP 1 REMOVE MOLD HEAD

MOLD CHANGE WITH OR WITHOUT HEIGHT CHANGE Remove head assembly.

Lower compression beam so mold shoes are about 1/4-1/2" (6.4-12.

Remove pallet from top of mold box. Install compression beam stops.

3 MOLD CHANGE WITH OR WITHOUT HEIGHT CHANGE STEP 1 REMOVE MOLD HEAD ASSEMBLY AND MOLD Close orifice ball valve. MOLD CHANGE WITH OR WITHOUT HEIGHT CHANGE Remove head assembly. Place pallet on top of mold box core bars. Lower compression beam so mold shoes are about 1/4-1/2" ( mm) above the pallet. Remove mold head bolts. Remove pallet from top of mold box. Install compression beam stops. Lower compression beam onto stops. Lower stripper beam Raise compression beam. Place clean pallet on the pallet table. Remove rear mold box nuts. 3 4

MOLD CHANGE WITH OR WITHOUT HEIGHT CHANGE MOLD CHANGE WITH HEIGHT CHANGE STEP 2 LOWER PALLET FEEDER Loosen front pallet feeder support clamps. COMPRESSION BEAM STOP Raise stripper beam.

4 MOLD CHANGE WITH OR WITHOUT HEIGHT CHANGE MOLD CHANGE WITH HEIGHT CHANGE STEP 2 LOWER PALLET FEEDER Loosen front pallet feeder support clamps. COMPRESSION BEAM STOP Raise stripper beam. Remove front mold box nuts. Loosen rear pallet feeder clamp bolts. Lower stripper beam about 1" (25.4mm). Use a prybar to dislodge mold. Lower stripper beam half way or so. Turn pump off Carefully work mold out of machine with mold box resting on pallet table. Remove mold box & pallet from machine.

5 Remove table hold down bolts. MOLD CHANGE WITH HEIGHT CHANGE STEP 3 CHANGE SPACERS MOLD CHANGE WITH HEIGHT CHANGE Lower stripper beam, beam will move down & the pallet table will be held up by support bars Change table spacers. Adjust height of stripper beam so that bottom of pallet table saddle is about 2" (50.8mm) above the pallet de-elevator. (Not shown) Place steel bars under the pallet table saddle so that the bars are supported by the pallet feeder and pallet de-elevator. Drop new table hold down bolts into place. (If needed) Install table hold down bolts, but do not tighten. Raise stripper beam so there is about 1/8" (3.2mm) gap between the top of the spacers and the bottom of the pallet table saddle. Raise stripper beam. Tighten table hold down bolts to 266 ft. lb. (361Nm) Remove bars. 7 8
