Modifying the Mold Base Assembly

In this section, we will add some features to the mold assembly to make it a bit more complete.

to start the creation of a cutout based on a part.

With the Control key pressed, select the plates 203030_036 and 203030046 and then click the middle mouse button
Then select from the model tree (inside MLD_HUB_BOTTOM.ASM) the part MLD_HUB_BOTTOM_WRK.PRT
Keep the cut by Reference for each part; select DONE twice.

You may open the cut parts to check that the workpiece block was cut out of the blocks.

to start the placement of an ejector pin, and select Ejector Pin > Add Set.

Select the placement point PNT1
Select the placement plane and orientation plane as follows:
to launch the PIN selection wizard: this wizard shows a list of standard pins to be used with your mold layout; we will select a standard pin component that will need to be cut to be adapted to the mold shapes
Select a HASCO MM, Z-40 type with a diameter of 3.5 mm and a length of 160 mm. After this is done, press the icon on the bottom of the Define Parameters dialog (AB->AB) to name the component in the context of your assembly layout.
Press OK to complete the pin selection
Hit Preview and in case the PIN appears in the wrong direction, you may select a new orientation with using the following buttons:
You can press OK now to complete the pin placement.

At this point, the standard pin is placed, it still needs to be adjusted to the mold requirements.

Select now TRIM TO GEOM from the menu manager (on the right)

Select the pin just placed as the one to be trimmed,
Select the design model that is the one used for the mold cavity design (in this case, mld_hub_bottom_ref) as the PART to be used to intersect the PIN,
Keep other default values,

Press OK and the PIN part is cut to be adjusted to the molded part.

The pin has been placed and trimmed to length, but the components it goes through are not drilled yet for the pin. Select CLEARANCE CUT from the menu manager (on the right).

When prompted, select the pin we just created, and the following dialog box appears
The quilt for the cut is proposed, but you still need to select the list of parts to be cut; pick Define, then select all parts that are intersected by the pin, and press OK twice when done.

You can now pattern the pin (use a reference pattern, since the original datum point was itself the leader of a pattern) and then reference pattern the cut for the pin to produce the final result.

You may open the parts of the mold layout individually, and you will be able to see all cut that are performed.

Congratulations! You have now successfully performed many of the main tasks in mold base design.
