Before you try drilling holes as Rob suggested, why not try to utilise the existing holes? You need to block them anyway, so you might as well stick a bolt in there and then cover it up with wax or plasticine.
Also, you said you made the flanges too large? What resin process will you be using to make the part? If you are doing infusion and the flanges are in the glimpses I can see of your mould, then those flanges aren't big enough. If you're doing wet lay then it will be fine, but for infusion I wouldn't have a flange any narrower than 10cm.

Thanks for the replys
Really like the countersunk method, will do that next time
I created huge flanges last time, so I'm thinking of scaling them back this time.
Forgot to mention I'm using the way composites epoxy mould kit.
Cheers,
Jamie

Two ideas for next time
Do as you did before but really beef up the side flanges and when finished remove all the loose flanges then use gravity/inerta to get the part out
Hard bash on one end of the flange while holding the other end should see your pattern flying out
Lots of shock isn't good for your gelcoat but will be ok for a one off home brew
Or drill 2 6/8mm holes through the top of your pattern (long as you don't mind destroying it) countersink them so when you bolt a countersunk bolt in its below the surface
Fill and polish on top of the bolt heads and you now have 2 studs coming out of the back of your pattern to strip out with

Hi
Secure it to a piece of sign board/Corex and build up around the sides with fillet wax.

Hi all,
So this is my first mould, it's not overly complex, however attempt number one was a failure.
The products worked brilliantly, and the detail was really good.
Sadly I had to break the mould as there was no way of getting a grip on the pattern to release it
Below are pictures of the part, it sadly I isn't flat so I built flanges around the edges last time.
The part is made from aluminium as well.
Any tips on how to mould this would be great.
