Casting from mold

[Henry_B]

I know I'm working backwards, but such is life.  I have modeled a mold and now I need to create the casting that would fill the mold.  I'm not finding much help, on this process.

Creo 10

Thanks

It depends on how the mold was built. Provide details on how you modeled the mold and what is available to work from to reverse engineer the part model. If the mold has shrink adjustment, what method did you use to apply shrink to the design.

In an assembly, I have serveral individual parts that stack together to create the center of a cone.  Another seperate part creates the outer wall of the cone.  I have all the parts assembled, and now I want to fill the void between the outer part and the inner parts stackup.  Does that make sense?

[tbraxton]

From your response I am assuming that you did not use the tooling/mold extension in Creo to model the mold. If you have the dimensions of the cone explicitly defined in the existing models, then you can model a cone and use relations to drive the part from the mold cavity and core. I would take the dimensions from the cavity (outer surface of the cone) and use that to drive the part model.

It looks like what I need is the mold extension.  In other software, it is as easy as subtracting parts from one another.  Oh well.

I wonder if you tried the assembly "boolean component operations" to subtract one model from another?

(I'm pretty sure this is basic software functionality; i.e., no extensions needed)

@pausob is correct you can subtract models/geometry with core Creo license. In order to use merge/cutout in assembly mode you need to have the advanced assembly extension or equivalent. Multibody Boolean operations (part mode) are included in all licenses for Creo AFAIK.

You definitely do not need the Creo Mold Design extension to perform Boolean operations.
