Creating a Form Ejection Component Reservation

You can create a Form Ejection Component Reservation to define a group of positions for an Ejection Component of a given type (Ejector, Ejector Pin, Core Pin, Flat Ejector...) relatively to a cutting surface (Core Surface and Cavity Surface).

  • These components can have different diameters.
  • The Form Ejection Component Reservation provides information such as the length of components at each position, or the need to generate an anti-rotation.
  • It also provides feedback to help you throughout Form Ejection Component Reservation.

This task shows you how to:

Create a Standard Form Ejection Component Reservation

You can create a Form Ejection Component Reservation in any product structure (template containing a Mold Project or an Insert Unit with generative Inserts), in creation or editing mode.

Notes:
  • The main characteristic of a Form Ejection Component is that this component needs be cut by the shape. As a consequence, the reference must be duplicated at instantiation because each instance has its own modified geometry.
  • Form Ejection Component Reservation keeps the associativity between the cut and the shape, provided the Ejection Component is long enough to be cut.
  • Because you can visualize the reservation space of the Ejectors before instantiating them, you can define the position of Ejectors early in the conceptual design, and instantiate them later in the detailed design.

  1. From the Mold Design section of the action bar, click Form Ejection Component Reservation .
    1. If you are working in a 3D Part, select a cutting surface and a support plane.
      The Form Ejection Component Reservation is created in the 3D Part.
    2. If you are working in a Product, select a cutting surface and a support plane.
      The Form Ejection Component Reservation is created in the Skeleton, if any, of the product.
      Tip: If several Skeletons exist, select one.
    If you are working in a Mold Project, a cutting surface and a support plane are proposed.
    • If the active product is an Insert Unit, a Multiple Layout Insert, or a Mold Base, the Form Ejection Component Reservation is created in the Concept Mold Skeleton.
    • With another active product, a warning is displayed.
  2. When requested, select a Skeleton from the list.
  3. When working in a Mold Project, select a Side from the list.
    A cutting surface and support plane are proposed automatically.
  4. In the other cases, or to modify the proposed cutting surface:
    1. Click once to highlight the cutting surface, if any.
    2. Click twice to select one.
    3. Click again to exit the selection mode.
  5. In the other cases, or to modify the proposed support plane:
    1. Click once to highlight the cutting surface, if any.
    2. Click twice to select one.
    3. Click again to exit the selection mode.
  6. Expand Dimensions to define the dimensions of the reservation spaces.
    1. Select or clear the Free Diameters check box.
      • When Free Diameters is not selected, the same Component Diameter, Hole Diameter, and Offset Parting are applied to all positions.

        All the circles positioning the Ejectors have the same diameter.

      • When Free Diameters is selected, each position has its own Component Diameter, Hole Diameter, and Offset Parting.

        The circles positioning the Ejectors can have different diameters.

      Note: Changing the status of Free Diameters resets the positioning of the Ejectors, if any, and deletes the sketch definition.
    2. Click one value to edit it in the window that appears.
  7. Click Sketch Points to define the positions of the components.
    1. In the Sketcher that appears, draw circles representing the positions of the Ejectors.

      The center of the circle is the position of the Ejector. The diameter of the circle is the expected Component Diameter.

    2. Exit the Sketcher when done.
  8. Click the color patch to apply a color to the representation of the Ejectors.
  9. In the Content tab, enter a prefix used to name and order the Ejectors.
    For example, enter EJ_ as the prefix. The Ejectors are named EJ_01, EJ_02 and so on.

    The Ejectors are listed, with their name and dimensions.

  10. Click Export to export the Form Ejection Component Reservation data to a .csv file.

The Form Ejection Component Reservation is created in the 3D area and in the tree.

It is editable: The dialog box is initialized with the Form Ejection Component Reservation data. You can edit all the values, move or delete positions, replace the cutting surface and the support plane by others and change the type of Ejectors.

Create a Form Ejection Component Reservation for Flat Ejectors

You can create an Form Ejection Component Reservation representing the positions of Flat Ejectors with their X axis tangent to a 3D curve.

  1. Activate the 3D Part where the Form Ejection Component Reservation is inserted.
  2. Start Form Ejection Component Reservation as explained above.
  3. Select the type of Ejectors, the Core Surface, and a plane in the Ejector System.
  4. Click Sketch Points
  5. Once in the sketcher, select the curve. Click Project 3D Elements to position the curve into the sketch.
  6. Create points on the curve projection to position the Ejectors and exit the sketcher.

The Flat Ejectors are positioned with their X-axis tangent to the curve.
