Quick injection mold jargon: A side = Side that stays in place in the press. B side = Side that moves with the clamp. Core = piece of the mold where plastic molds onto/around. Cavity = piece of the mold where plastic molds into.
In the photos you can find individual photos of what all pieces are needed for each step. The last 4 photos show the order in which the mold should be assembled. Starting with the A side, B side, Ejectors, and back plate/supports.
BOTH A SIDE AND B SIDE CAVITY/CORE BOLTS ARE INTERCHANGABLE.
BOTH A SIDE AND B SIDE MOUNTING BOLTS ARE INTERCHANGABLE.
EVERYTHING ELSE PRINT THE QUANTITY WITHIN THE PARENTHESIS, IF NO QUANTITY IS MENTIONED THEN ONLY 1 IS NEEDED.
PRINT SETTINGS/INFORMATION:
Layer height: 0.1mm - 0.2mm
Walls and shells: 3-5
Materials: Dealer's choice, I used PLA.
Supports: On most of the large components, I used tree/organic supports on all pieces. Mind the screw holes, threaded holes are a nuisance when tree supports wiggle in there. All bolts and pins can be printed without supports with ease.
Brim: I used a 5mm brim on them just to ensure no warpage so assembly went smooth. Only used on the large components.
The assembly tool is advised to be used, the bolts have a 8mm square hole in them. Unsure what other tool would be useful.
For printability reasons I did not include the runner/sprue model. Frankly I never made it because it would be a nightmare to mess with. There is also no water jacketing, still working on a way to model that and have it be shown. A cutaway mold in the future??
I apologize for the delay on this. I have another that was meant to take the place of the OG one as a more "accurate" example. Time has sadly not been as abundant as I would have liked.
