Mold Tools - Tooling Split

After you define a parting surface, use the Tooling Split tool to create the core and cavity blocks for the model. To create a tooling split, you need at least three surface bodies in the Surface Bodies folder: a core surface body, a cavity surface body, and a parting surface body. You can create a tooling split for multiple solid bodies (for example, one mold of multiple parts, or one mold for multiple instances of the same part).

This model includes an interlock surface. It was created using the Ruled Surface tool and it was finished using other surface modeling tools.

To create the tooling split:

  1. Select a face or plane on which to sketch an outline that separates the core and cavity segments.

  1. Click Tooling Split (Molds Tools toolbar) or Insert, Molds, Tooling Split.

    A sketch opens on the selected plane.

  2. Sketch a rectangle that extends beyond the model edge, but is within the parting surface boundaries.

  1. Close the sketch to open the Tooling Split PropertyManager.

Under Core , the Core Surface Bodies appear.

Under Cavity , the Cavity Surface Bodies appear.

Under Parting Surface , the Parting Surface Bodies appear.

You can specify multiple disconnected core and cavity surface bodies for one tooling split.

  1. In the PropertyManager, under Block Size:

  • Set a value for Depth in Direction 1 .

  • Set a value for Depth in Direction 2 .

  • Select Interlock surface if you want to create a surface that helps prevent the core and cavity blocks from shifting. An interlock surface is created along the perimeter of the parting surfaces.

    Set a value for Draft Angle . An interlock surface typically has a draft of 5°.

With most models, creating an interlock surface manually provides better control than relying on automatic creation.

  1. Click .

    Two solid bodies appear (a core body and a cavity body).

You can use Move/Copy Bodies (Features toolbar) to separate the tooling bodies to facilitate viewing them.
