From the Cimatron E opening screen, click the Mold Project icon.

The Mold Project Setup Wizard is loaded.

Name the main assembly: Mouse cover

Select Create a new folder to place the main assembly in a new folder.

While loading the project you can already decide on the layout and where to position your parts.

Quick Tour

84

You can either create a new layout part or load one from a predefined layouts library.

The Mouse cover is a single cavity mold, so accept the default Layout part Layout-1-Cav-mm i.e. a single cavity layout part.

Click OK.

Quick Tour

Cimatron E6 85

Step 2 - Load Work Part

Note the assembly structure.

A mold assembly has been created. This assembly consists of a Fixed Side, Movable Side, and Ejection System sub-assemblies.

Notice the Parting Guide. Both guides: Parting and Mold, guide you through the logical steps of the Mold Project process, from start to finish.

There is also a Parting sub-assembly, which is activate by default and will be used first.

Quick Tour

86

The Parting sub-assembly will later include the work parts and parting faces parts. This helps to organize the spilt work.

The outer blue box is a simple sketch that represents a preliminary mold base size. It can be edited to any size just to help with the layout until there is a real mold base built.

The inner box represents the bounding box work part.

Quick Tour

Cimatron E6 87

Step 2a - Load Work Part

We will now load the work part and position it onto the UCS in the Layout part.

Click the Load Work icon in the Parting Guide.

The Load Work Parts dialog appear.

Master part: The original document received from the product designer, used as a reference for the working document.

Work part : All necessary operations for the mold part creation are performed in this document . Operations include fixing the model, splitting the model, creating parting lines and parting surfaces, creating the mold UCS and the mold part objects and exporting them. The working document is associative to the master document.

Click the Open file button.

Quick Tour

88

From the Cimatron E Explorer select the Mouse cover.elt file (located in the \\Tutorial Work Files \ Getting Started directory).

Accept the default parameters of the Document Name, Units (mm) and Shrinkage Compensation of the part.

Click OK.

Quick Tour

Cimatron E6 89

Step 2b - Load Work Part

Place the part on the layout coordinate system.

This operation also creates a coordinate system in the work file, a Work UCS feature.

The Work UCS is the UCS created within the work part, by which the work part is placed in a mold.

Pick the UCS indicated by the arrow in the picture below:

Do not edit the Work UCS.

Quick Tour

90

Click the Edit Work UCS button, to edit the location of the Work UCS.

Answer 'Yes' to continue the operation.

Quick Tour

Step 2c - Load Work Part

Change to ISO view, and select the Wireframe display mode.

Move Work UCS to the lower middle point of the bounding box.

Quick Tour

92


Click OK to approve the operation.

Quick Tour

Cimatron E6 93

Step 3 - Split the model into core and cavity

Note that the Work Part now appears in the Assembly Tree.

Switch back to Mixed Render mode and hide the Layout part, for a clearer display.

Select the Parting tab to display the parting tree.

Double click the Mouse Cover-Work, to activate the part.

Quick Tour

94

Click the QuickSplit icon.

Accept this setting and click OK.

Quick Tour

Cimatron E6 95

Step 3a - Split

To attach it to the blue (upper) set, move the mouse over the blue set and press the Middle

Mouse Button.

Quick Tour

Cimatron E6 97

Exit the Quick Split function, via the Close button.

Quick Tour

98

Step 4 - Draft Angle

Click the Draft Angle/Draft Angle icon.

Press the Show dialog tab.

The draft angle of the model is automatically color-coded according to the default color map values.

You may change the colors as well as the values.

Quick Tour

Cimatron E6 99

Ensure that there are no red faces (undercuts) in the model and exit the Draft Angle Analysis.

Quick Tour

100

Step 5 - Create Parting Lines

The parting curve will be automatically created. Each entity in the parting curve gets the attributes of the faces it belongs to.

The preview parting lines are not only for analysis purposes. Once the preview is performed, any curve/surface that is created using the edge of the parting line will automatically get parting attributes. The parting line preview can be updated at any stage, after changes to the part.

Verify that the UCS is active, by Double Clicking on the UCS.
