Creating Mold Core + Cavity 1

[alperin]

For our latest project we are creating a silicon mold to encapsulate a wire splice. The part itself is very simple geometry, however, this is my first time making a mold and I am having trouble.

I have basically been following the solidworks tutorial for the mold of the phone body, but, although my geometry is much simpler, I am not about to get the final core + cavity. Essentially, I can only apply the shut off surface feature to two of the three hole faces, and when I go to split the core and cavity using tooling split, I get an error that I cannot knit sheets together.

Can someone please take a look at the part and my feature tree and give any insight as to what I am missing?

You missed a Shut-off.
Put in history before Parting line.
Use the workplane to Split the faces of the part (the shut-offs) (I would have extruded mid-plane rather than creating a new user workplane)
Then do Parting line.

I would not even model the holes (unless you are interested in the volume of fill material) as the wires will form a Core). (you could do a configuration if you desire both) This would make the split much easier to create.

Actually I like your approach of foregoing the wire holes. I can add them after the core and cavity have been created. I am still getting errors when I go to tooling split.

I removed the extruded cut features taht make the wire holes. Created the parting line and surfaces, and when I go to split I get the error "cannot knit sheets together" if I select interlock surface. If I don't, then I get the error: "the parting surface must be larger than the boundary of the sketch" I have tried playing with the geometry of the cross section sketch, but continue to ge thte same error.

Hi
You need to extend the Parting Surface to beyond your tool boundary sketch
On your model, I set it to 25mm and it works OK
