Making a Mold From an imported part

[Tom-ATCNC]

Hi All,

Looking for some advice on where i have gone wrong with this process.

I have had a part emailed across to me that this company wants a vacuum forming tool made.

I have followed the procedures on videos but i get this result. I split it and move top part of mold i can see the pattern there but the void is covered.

Any help is greatly received.

Kindest Regards Tom

Look to me like you have a number of bodies occupying the same or adjacent space, try toggling the lightbulb to make sense of the model/s.

(Not clear on Ipad, to see which is which).  

Section analysis shows both are hollow.

Might help...

Looks like its under cut, so that thin wedge of material shouldnt be there,

Have i done something wrong in the splitting of the body for this to happen?

Kindest Regards Tom

 Does the file show the mold or the part?

One technique for creating a mold is:

1. Change to Patch workspace.
2. Delete outer faces of model.
3. Thicken the remaining inner faces.

Draft will have to be added where necessary.

Morning All,

After alot of patience and playing around i found the fault which was operator error.

Basically the part that was sent had drafts on all sides. so when extruding the patch plane to get a split line it wasnt level with the base but perpendicular to the drafted side,

On extruding the split line i added a taper to counter the draft angle resulting in what i was trying to acheive.

Thank you all for your time.
