Create a cooling cycle using a 3D sketch

First we will create a 3D sketch using the standard SolidWorks tools. Make sure that the Automatic relations in the System Options tab under the Sketch Relations/Snaps section check box is marked,

¾ Click the RHM button on and select Show Only in the MoldWorks FeatureManager Tree.

¾ Show Isometric view in Wireframe mode.

¾ Select the right face of the Plate3.

¾ Click on the 3D sketch icon.

¾ Click on Line and select the right view.

¾ Create a point as shown below (halfway between the plate and the insert towards the left side of the insert - doesn't have to be exact).

¾ Select the front view and draw the 3 segments as shown below. (Again don't bother with exact dimensions, although the line should pass through the middle of the insert base, about halfway up, and then to just before the screw across the insert)

¾ Select the top view and draw the next 2 segments across the insert and back to approximately the vertical point where the line penetrated the insert from the plate.

¾ Finally select the front view and finish the sketch as shown below.

Below is an isometric view of the sketch.

¾ Exit the Line menu.

We can now dimension and add relations to the sketch i.e. Fix the first and last points to the plate face with the On Surface relation, make sure that the lines are symmetrical and the end points on the same vertical level etc. This can also be done after creating the cycle.

¾ Select the Heat Exchange folder under the MoldWorks FeatureManager tree. (without exiting the sketch)

¾ Click on the RHM button and select the menu Insert Cycle…

If the 3D sketch is still current it will be automatically selected in the Selected sketch(s) parameter box of the Positions tab in the Heat Exchange

PropertyManager. You can also select this menu from the MoldWorks >

Heat Exchange > Insert Cycle… or relevant icon .

Depending on the sketch you have created you will now see something similar to the picture below.

In this example we see that one of the pipes is in red meaning that it is in collision with a component.

Note that if the current view was shaded then MoldWorks will create a temporary transparency to allow you to see the preview of the pipes and components.

If you have a collision at this stage, exit the menu edit the 3D sketch and define adjust the lines from the top view as shown in the picture below, making sure that the lines do not cross or come close to the screws or the core pins.

You can activate the Insert Cycle… menu while in the 3D Sketch which will close the sketch and add it to the Heat Exchange Property Manager.

¾ Click on Preview Cycle to show only one pipe. You can work with all the pipes showing and the current pipe is highlighted in green, or just with the current pipe showing.

Now we are going to browse through the cycle pipe by pipe and adjust the pipe and component definitions. MoldWorks creates a plug for every pipe and makes a decision based on distance as to which face to extend the pipe. If a line segment crosses a part boundary then a o-ring is created.

¾ Select the Cycle tab. As you can see the pipe is diameter 10.00 mm and extension 10.00 mm as defined in the settings (for inch documents the settings are .5 and .1 respectively). You can change these setting prior to

entering the PropertyManager by RHM button selection on the Heat Exchange folder and clicking on the Settings… menu.

¾ Select the Connector icon under the components dialogue; see that the components preview changes.

¾ Select Connector Type 2 from the Type

parameter box, and key-in a value of 43.00mm in the Face offset parameter box.

¾ Click on the Right Arrow in the Cycle Pipe(s) dialogue to browse to the next pipe. Next component is a pipe with o-ring. Notice that this pipe is defined in the plate even though the original segment crossed into the insert as well.

¾ Click on the Right Arrow again. The other o-ring appears.

¾ Click on the Right Arrow again.

¾ Select the Connector icon under the components dialogue and leave the default choice.

¾ Click on the Right Arrow again. The first pipe in the insert is now displayed.

¾ Key-in the Diameter parameter as 8.00 mm. We will create the pipe cycle within the insert with diameter 8mm.

¾ Click on the Right Arrow again. Here we see that the middle button has changed to a warning sign.

This means that there is more then one possible solution for the pipe extension direction. Clicking on the middle button will toggle the preview through the possible solutions, in this case either side or both sides,

¾ Toggle until the pipe extends to the near side of the plate.

¾ Key-in the Diameter parameter as 8.00 mm.

¾ Click on the Right arrow again. Here we see that the middle button has changed to a warning sign again. In this case choose the both side option.

¾ Key-in the Diameter parameter as 8.00 mm, and Click on the Right Arrow again. Again an ambiguous situation, choose the near end extension side.

Don't forget to change the diameter to 8mm. (You can always click on the left arrow to go back or on the Right Arrow to carry on until you reach the pipe again).

¾ Key-in the Diameter parameter as 8.00 mm for the final pipe.

¾ Select the Position tab and click on Preview Cycle. You should see the following preview.

¾ Click .

Notice that the same cycle with components is created in the instanced insert as well. We will show how to edit the cooling cycle created through this menu under the Editing Tools chapter.

You can also create the same cooling cycle with the standard add component wizard using the cooling section, however, the new method that we have shown above is recommended since it creates the hole wizard holes and also the components. The editing is far more comprehensive.
