Add Ejector

When adding certain catalog components (such as ejectors or cooling components) to faces, you can change the diameter of the added parts by changing the diameter of the sketch circle used to position them.

This means that ejectors with different diameters may be added easily and quickly in a single operation. You can add different sized ejectors simply by changing the diameter of the circle used to position them. Varying ejector heights can be adjusted automatically by the system.

The image below shows ejectors and return pins with different diameters and heights.

General Interaction

The general interaction is similar to that for adding mold parts. The only difference is the dialog displayed during the required step 1.

Required Step 1

1. Select an ejector.

   The Add Ejector dialog is displayed with the appropriate catalog Category and Sub-Category component types automatically displayed. See the Example Catalog Component Selection Process, below.

   

   Example Catalog Component Selection ProcessExample Catalog Component Selection Process

   When selecting a catalog component, the Component Selection dialog is displayed with the appropriate Category component type automatically displayed (depending on the function invoked) and Sub-Category component types displayed for selection.

   An example catalog component selection process is described as follows (in this case, for Mold Components):

   The appropriate Category component type is automatically selected and the Sub-Category component types are displayed for selection. The Item row of the dialog displays a small image of the actual components, which enables easy recognition of the items. Pick a component item from this row, select the required size record from the catalog table and then position the component on the assembly. If required, perform the optional steps of this function. For more, see Component Selection.

    

   1. Select the required catalog (1 in the image above).
      Hover over the displayed catalog name to display a tooltip showing the catalog location in your computer. The default catalog location can be set in the Cimatron Control Panel.
      
      To change the catalog, either browse to the required catalog location , or select a catalog from the dropdown list; this list contains the last 10 catalogs used.
      
      When a catalog is selected, the appropriate catalog Category and Sub-Category component types are automatically displayed (depending on the Catalog type).
   2. Select the required Category and Sub-Category component types (for example, 2a and 2b in the image above). When you select a Category component, the appropriate Sub-Category components are automatically displayed.
      When you select a Sub-Category component type, if placing or size rules have been applied to this component, the Rule Information button and the Placing/Size Rules checkboxes become available for use, as shown below. These rules can be edited as required using the Rules Editor.
      
   3. Depending on the Sub-Category component selected, the appropriate Item components are then displayed. Select the required component item (for example, 3 in the image above).
      When the component item is selected, the Catalog Table and Properties of the relevant component are displayed.
      
   4. Click the Properties buttonProperties button  to hide the Properties and to expand the Catalog Table to the full width of the dialog.
   5. Select the required record from the catalog table and click OKOK  to select the catalog item or click CancelCancel  to exit.

    

   When the catalog item is selected, press the Calculate Length button to displaydisplay the recommended minimum and maximum ejector lengths.

   

   The remaining interaction is identical to that for adding mold parts.

2. If the Use Placing Rules checkbox is marked:

   • The minimum and maximum ejector lengths are then calculated.
   • When the Catalog Table is displayed, an appropriate catalog item is selectedappropriate catalog item is selected according to the length calculation. The L dimension will be the closest rounded up dimension that fits the maximum length. The D dimension will be the minimal size that fits the L. (D is the first leading dimension and L is the second leading dimension).

     

   Click the Calculate Length button to displaydisplay the recommended minimum and maximum ejector lengths and show a graphic representation of these lengthsgraphic representation of these lengths.
