Adding a Side Core

The Core tool extracts geometry from a tooling solid to create a core feature.

For example, suppose the telephone handset has a hole in its side for a cord clip. The faces of the hole are undercut faces (trapped areas that would prevent the part from ejecting from the mold). You need to create a side core. When the main core and cavity are separated, the side core slides in a direction perpendicular to the motion of the main core and cavity, enabling the part to be ejected.

To create a core:

1. Create a core sketch on or near the inside face of a tooling body. In this case, the sketch was created on a plane parallel to the end face of the cavity body and through the outermost point on the part.
   
   

The angled sides in the core sketch provide draft for the vertical movement of the cavity. The draft angle specified in the PropertyManager provides draft for the horizontal movement of the side core.

2. Click Core (Mold Tools toolbar).

3. In the PropertyManager set options such as Extraction direction, Draft Angle, End Condition, and Cap ends, then click .

A new body is created for the core and is subtracted from the cavity body. In the FeatureManager design tree, in Solid Bodies , the new core appears in Core bodies .
