Step 4: Sliders and Core Pins

In this section, we will briefly describe techniques to create parting geometries like sliders or core pins or any other necessary extra models required to complete the mold cavities. You may remember from our Draft Check Analysis that the logo requires a slider.

will activate the modeling features to create the geometry of the sliders or other parting geometries.

will allow the creation of solid models directly.

In our case, we will use to create a geometry that describes the slider we need to design to be able to make the logo: press and the modeling environment is activated.

Pick Insert > Extrude and RMB Define Internal Sketch and then select references as shown in the image.

Select proper references:
The define the following sketch:
Finally extrude UP TO SURFACE and select the curved surface where the logo is:
Validate the feature by picking the green checkmark in the dashboard.

To complete this slider shape, we will add another extrude, using the same sketch plane as before (use previous) and sketching as follows:

Then, validate the feature, and then Validate the completion of the mold geometry with the side tool bar VALIDATION button:

The resulting features are:

Note: We will not worry about the logo shape here, you'll see later that the mold splitting process will cut the logo geometry from the slider automatically. However, prior to validating the geometry with the side tool bar validation button, you could have picked Edit > Trim > Reference Part Cutout to do the same thing.

Hit again to create core pin geometries for our mold. Folloiwng the same general steps as above:

Extrude two cylinders as shown below:
- The first cylinder goes into the reamed hole in the part.
- The second cylinder stops at the parting plane.
- Note: you could also create this as a single Revolve feature.
Validate this Pin.

Now, you may create an Axis Pattern of the pin to have 4 of them. (RMB > Pattern; pick Axis from the pull-down...)
