To Predefine an Ejector Pin with a Layout Curve
To speed up the process of defining ejectors, you can use this feature to predefine ejector pins with layout curves directly in the article model. As a result, you get a better view of where the ejector pins are placed on the article and whether their dimensions fit into the design. You can then assemble all predefined ejector pins at one time within the mold base assembly.
1. Prepare the models where you need to predefine ejector pins:
b. Select one or several models where you need to predefine the ejector pins. This is usually the article model.
c. Click OK. The Select dialog box closes.
d. The selected models are prepared for predefining ejector pins.
2. Predefine the ejectors in the article model:
a. Open one of the models you prepared in the previous step.
b. Click > to predefine an ejector pin.
c. Select a supplier, the subtype of the ejector, and edit the dimensions or the options. For more details, see
To Define Components d. Note that the assembly placement constraints for
Surface and
Orientation Surface are already selected and show the Select icons
while the placement constraint for the
Point is not selected and shows the To be Selected icon
e. Select a point on the article to place the ejector pin.
f. Note that under
Options, the
Predefine Componentcheck box is selected.
g. Click
to assemble the layout curve and to preview the real position and size of the ejector pin on the article
h. Make as many changes as necessary and preview the results by clicking
.
i. Click OK to apply the changes and close the dialog box, or click Cancel to close the dialog box and discard all changes.
j. Repeat these steps until you have defined all required ejector pins
3. The third step of the process is to assemble all predefined ejector pins at one time within the mold base assembly:
a. Close the window of the article model and open and activate the window of the EMX mold base main assembly.
c. Select one or more models that have predefined ejector pins. EMX assembles the ejector pins with the predefined settings including components and cuts. For all ejector pins that were assembled successfully, the layout curve created in the previous step is removed.
Identify ejector pin owner models.
Assemble predefined components.
