Mold design subtraction.

[Anonymous]

Just had a mold designer here ask me for a method in IV to do a part subtraction for mold design.

Basically he is looking for something as simple as a boolean operation. I could come up with many ways through adaptive assemblies but they were mostly complicated and drawn out processes.

Anybody have a quick clean method for this?

Look into derive.

Derived Component ---> Substract?

I think you will find that a simple method will only work on simple
parts. Parting planes and cores add to the complexity. Derived
components work well once you get the concept. Basically, you put all
your components in an assembly and subtract, add or ignore various parts
to derive various mold components;i.e. cavities, cores, etc.

Thanks to all of you,

I just did a simple example for the molding eng to show the steps involved in the adaptive subtraction.

Just wanted to show some method that IV could do this.

Good luck getting it to work on IMPORTED data though.
Most of the files I get imported into IV fail on these
more complex commands, though I have some workarounds
for adding some features when they fail. Not sure you
are using imported data or not, just thought I'd point
out that issue.

You're certainly right about the IMPORTED data problem. Fillets are
major problem, they can stop a simple part split before your finger is
off the button. Seems that many designers have heard that sharp corners
will cause stresses in molded parts; so they hit the "fillet all"
button. Without the fillets, most of the IV operations would have been
fine.

We have a package that could help you with easy and complex Inventor parst at:

http://www.progetti3d.it/?lingua=uk&progetti3d_public=9e6cb8b166f19b4c2045f49e254e63ec

It is easy to create splitting surfaces and all what you need to design molds.

I pasted on the link to our molders.
They just bought Pro-E but may be they will have a look since we already have IV.

Hi,

you should also look here:

Mold Factory is a copmplex application especially for mold-design, which includes a variety of functionalities for designing molds, e.g. "Mold Parting - Parting Surface".

Thank you Petra Benker for this information! I Will have a look at your web site.
