Creating Waterline Circuits

Waterlines are assembly-level features that you can use to create water channels in the mold model.
• Specify the waterline circuit diameter.
• Sketch the waterline circuit.

– Section should contain only linear entities.
• Specify the mold components to be cut.

Waterlines are assembly-level features that you can use to create water channels or circuits in the mold model. Waterlines are drilled holes in the mold model components. The waterline circuits convey cooling water through the mold components to control the cooling of molten material. The speed of cooling the mold is directly related to the profitability of the entire mold product line.
To create a waterline circuit, you must specify the following:
• Name — Determines the name of the waterline as it displays in the model tree. You can accept the default name if desired.
• Diameter — Enables you to specify the diameter of the waterline hole. You can either type a value or accept the default diameter value.
• Circuit — Enables you to sketch the waterline circuit path. You must specify the sketch plane and reference plane and orientation. The sketched section should only contain linear entities. This is because the waterline path is ultimately drilled into the mold components. As you sketch the circuit in Sketcher, a dashed line displays on either side of the sketch line, as shown in Figure 1. This dashed line denotes the actual section diameter of the circuit.
• Intersected Parts — Enables you to select the mold components that the waterline circuit intersects. The following options are available for
determining which components are going to be intersected, or cut, by the waterline:
– Automatic Update — When this check box is selected, the system automatically determines which mold components are cut by the
waterline feature. All other selection options become grayed out. When this option is used, the automatic intersection excludes the reference
models and any molding.
– Advanced Intersection — When this check box is selected, the system enables you to manually define the display level separately for each
– Select a component to intersect — Enables you to manually specify which components are cut by the waterline feature.
– AutoAdd — Similar to the Automatic Update check box, when this option is selected, the system automatically determines which mold
components are cut by the waterline feature.
– Info — Enables you to display information regarding the waterlines feature in the browser.
The mold components that are specified display in the Intersected Comps dialog box. To remove any components displayed, you can select the
component and either click Remove, or right-click and select Remove.
By default, even though the waterline is created as an assembly feature, you can also view it within the individual mold component. The feature displays in the mold component model tree as an assembly cut. You can modify this behavior, however. The right column of the Intersected Comps dialog box displays the visibility level for each intersected component which, by default, is the mold component itself. You can click in this field and modify the visibility level of the component to the mold model assembly. When this change is made the waterline is only visible from within the mold model, and not within the individual mold component.
Because waterlines are actually drilled holes in the mold components, the end of each waterline segment displays as a drill point, rather than a flat or rounded edge.
You can create waterlines any time after the workpiece and reference model are assembled. When the volumes are split, any previously created
waterlines are automatically subtracted from the mold volumes along with the reference model.
