Bender Posted November 20, 2008 Report Share Posted November 20, 2008 One of our aluminum jig trailer molds had too thick of claws so I decked .040" off and now it is very difficult to pour evenly. I'm wondering if anybody has added a backing plate, alignment pins, and clamping screws to a previously one piece mold successfully? The only thing that I am worried about is venting the extremities. I think I will try without vents first and then if needed add some small grooves. Just looking for tips and experiences. Quote Link to comment Share on other sites More sharing options...
GB GONE Posted November 20, 2008 Report Share Posted November 20, 2008 I have added a portion onto a mold to make just part of it 2 piece. It was not a production mold just a brush hog type mold for my use. I made a pop "topper" for just the portion of the mold I needed more plastic for the hook to be placed. All I did was fashion the "other side of the bait", mold it in pop as a one sided bait and then drilled through the pop to make a pour in area. The plastic did overfill a bit on a portion just past the pop topper but not bad. Did have a little flashing as well but not bad. I think I trashed the pop portion of the mold in my recent move but will look for it so I can give a visual. Jim Quote Link to comment Share on other sites More sharing options...
Delw Posted November 20, 2008 Report Share Posted November 20, 2008 just take a piece of flat stock and clamp it to the one piece mold. if its a vent problem use a hacksaw to cut vents into the mold. Quote Link to comment Share on other sites More sharing options...

I certainly have no experience with aluminum molds but I have been using POP and DWP for years now, but fell upon TU recently and learned a lot more than I achieved through my self taught approach. I designed and built several DWP molds to work as 1-piece and 2-piece molds to use a flat stock as 1/2 of the mold. Turned out that was smart as the areas of concern were like your claws, too thin to pour. This link, also got picts of it: TU taught me this, its long, pics too. I do not see why you cannot do the same but you will need injection or suction, I like suction on the vents to fill out my molds. I use a tube connected to a vacuum cleaner and vent the ends of thin tails through a small channel to a manifold collection. Each piece has its own tube. If you vent all pieces to suction at once you will by the laws of physics increase the airpressure as you successively fill each piece and eventually will likely suck too much molten plastic into the vent.
