Engineering Design with SOLIDWORKS® 2018 Extrude and Revolve Features

If the wall thickness is too thin, the part will structurally fail. If the wall thickness is too

thick, the part will be overweight and too costly to manufacture. This will increase cycle

time and decrease profits.

There are numerous types of plastic molds. SOLIDWORKS contains a variety of Mold

tools to assist the designer, mold maker and mold manufacturer. For a simple Cavity

Mold follow the following steps:

• Draft analysis. A draft analysis examines the faces of the model for sufficient draft, to

ensure that the part ejects properly from the tooling.

• Undercut detection. Identifies trapped areas that prevent the part from ejecting.

• Parting Lines. This tool has two functions:

o Verifies that you have draft on your model, based on the angle you specify.

o Creates a parting line from which you create a parting surface. The Parting Lines

tool includes the option to select an edge and have the system Propagate to all

edges.

• Shut-off Surfaces. Creates surface patches to close up through holes in the molded

part.

• Parting Surfaces. Extrude from the parting line to separate mold cavity from core.

You can also use a parting surface to create an interlock surface.

• Ruled Surface. Adds draft to surfaces on imported models. You can also use the

Ruled Surface tool to create an interlock surface.

• Tooling Split. Creates the core and cavity bodies, based on the steps above.
