Inventor 2025 Injection Molding Problem

[bartalos_bendeguzedu]

Hello everyone ! 

I got stuck while designing a tool.
I've tried every way I know how but it always runs into errors.
Either it runs into a surface error , or it does not contact the runoff surface. The attached photo shows where I got stuck.
(Not the patching surface ) where the part is turned back and there are two small protrusions on the edge

Can anyone help me with this ?

Are the runoff surfaces on a planar face? If yes, you can use the Create Runoff Surface to generate them and just adjust the directions of some edges or use Bounded Runoff to create them manually. If not, you may use other runoff surface commands to create them manually, such as Radiate Runoff.

thank you for your reply ! 
I tried what you suggested, but unfortunately I was not successful .

This is the position of the piece in the mould .

You can see the silhouette on which the runoff surface should be placed.

You can't do the surface on the part in the first picture because if you pull it parallel to the Y axis it cuts through the piece and I couldn't figure out how to avoid that.

Can you help me with this ?

Maybe it is a better view.

OK, the silhouette curves may not be on a planar plane. The last method is editing the moldable part and create the parting surface manually by normal surface tools. And then back to Core/Cavity to use existing surfaces as runoff surface.

I tried that aswell , edited the part , I created the surface , and then I got error message : there are gap between the eges 0.000000 inch , so i have no idea what should I do .
