Creating Coolant channels 

This task shows you how to create coolant channels. You can create a coolant channel in any plate in a mold.
There are several restrictions concerning the manipulation (notably when copying, pasting, deleting, dragging and dropping) of components and drilled CATParts. Click here for more information.
The points used to create coolant channels can be simple points, vertices at the ends of a line, projected points or points from a sketch. You can either:
  • select one point after the other, or 
  • select a line in which case the extremities will be used, or
  • select a sketch. A coolant channel is created or each element in the sketch. 

If the elements used to build coolant channels (points, lines, ...) are created with an external reference, those reference links are broken at the creation of the coolant channels to avoid any lifecycle problem.

  1. Open Split.CATProduct in the samples/Split directory.

  2. Double-click CoreCooling (in CoreCooling1). This opens Part Design.

  3. Click the Create a Point icon from the Wireframe and Surface application. 

  4. Select a point from the planes on which are based the core plate and the cavity plate of the mold.
    Click OK to complete the creation of Point1.

  5. Turn the mold round and select a point on one of the four other planes. Click OK to complete the creation of Point2.

  6. Double-click Product1 to come back into the Mold Tooling Design workbench.

  7. Click Add Coolant channels . Select the two points that you just created because they are going to be the end points of the coolant channel. The Coolant Channel definition dialog box is displayed and the coolant channel is previewed. You may modify any of the parameters you choose and the modifications are simultaneously previewed.

  8. Click OK to create the coolant channel. You may edit the coolant channel once it has been created.

  9. A set of parameters define the geometrical characteristics of the coolant channel, as shown in the dialog box.

    Reverse reverses the first and last points (first becomes last and last becomes first) when both points belong to the planes that define the CoreCooling or CavityCooling
    If one of the points does not belong to one of these planes, the complementary solution is proposed when clicking on the Reverse option.

  • In creation mode, when neither element (point or end point) used for creating the coolant channel belongs to the planes that define the CoreCooling or CavityCooling, the user is proposed two solutions. 
  • The reverse option is used to display the complementary solution:
  • The Reverse option cannot be used at final completion of the coolant channel. However for each element of the sketch, the user may choose the reversed solution by clicking on the following dialog box which is automatically displayed when required.
  • All coolant channels are created simultaneously and share the same parameters. But they are independent (and are displayed so in the specification tree) and may be edited individually once the creation is completed.
  • You can also use elements from the sketch but you need to select them one after another and create the coolant channels individually.
  1. To edit the channel once it has been created, you select it in the specification tree using the Coolant Channel Edition option in the contextual menu or graphically with a simple click on the object. The parameters that can be changed are the same as those for channel creation.

  2. If you wish to edit parameters other than those required for channel creation, double-click the coolant channel either in the viewer or the specification tree. A dialog box is displayed that allows you to edit the hole properties.


Deleting a coolant channel

  1. Delete a coolant channel by:

    • editing CoreCooling or CavityCooling  (depending on where the coolant channel was created)
    • selecting the coolant channel you want to delete in the CoolingBody
    • use the contextual menu to delete it.
