To Assemble Ejector Pins
Download 32 To Assemble Ejector Pins to start from with this chapter.
Assemble the Ejector Pin Target Subassembly
  1. Click EMX Assembly ▶ Structure ▶ Image Add Subassemblies
    The Subassembly dialog box opens.
  2. Select TUTOR_MH from the Subassembly pull-down list.
  3. Enter TUTOR_MH_EPINS into the Name input panel.
  4. Select Ejector Pins from the Function pull-down list.
  5. Click OK to leave the Subassembly dialog box.
    A new EMX Subassembly will be added to the mold base assembly.
    With the assigned Ejector Pins function all upcoming ejector pins will by default be assembled to this subassembly.
Define the Ejector Pin Properties
  1. Click EMX Assembly ▶ View ▶ Show ▶ Image Moving Half.
  2. Select EMX Components ▶ Ejector Pin ▶ Ejector Pin Image.
    The Ejector Pin dialog box opens.
    TUTOR_MH_EPINS is preselected as Subassembly.
  3. Select knarr from the Supplier pull-down list.
  4. Select 37111 from the Types pull-down list.
  5. Set the DM1 value to 4 mm.
  6. Define the references
    1. For (1) Point select a point from the multi point feature PNTS_ROUND_EPIN_4MM in the ARTICLE_REF.PRT model.
      After the Point has been selected the offset between the point and the default reference surface will measured.
      This offset (157.541 mm) is shown in the Reference Distance line of the Dimensions.
      The next valid instance is chosen automatically in case an instance of this ejector pin exists, where the LG1 exceeds the measured distance.
       Note
      A warning dialog appears in case the required length for the selected diameter does not exist in the catalog.
    2. The (2) Surface reference will be selected automatically and is used to align the head of the ejector pin. By default the bottom face of the first ejector retainer plate in the mold base is used.
       Note
      A different surface can be selected by clicking the Surface button and select the desired face in the model.
    3. The (3) Orientation surface is preselected. The MOLDBASE_Y_Z of the skeleton model is used by default for all ejector pins.
  7. Click Preview to visualize the ejector pins.
    On each point of the multiple point features an ejector pin is previewed.
     Note
    It is not possible to place a single ejector component on a single datum point within a point feature containing multiple point instances. The same ejector pin model will be placed on all points.
  8. Enable the option Individual ejector models on each point.
    This option is necessary to be able to Trim the ejector pin heads after finishing the ejector pin placement.
     Note
    With this option an individual ejector pin model will be placed on each point.
    This is automatically used for:
    • Ejector pins defined on multiple point features with different heights.
    • Trimmed ejector pins on multiple point features.
  9. Make sure Auto Length is activated.
    With this option the length of the ejector is set to the Reference Distance value displayed in the dialog box.
  10. Switch to the Options tab and click Pattern for all models to add the ejector pins (and their cutouts) to both ARTICLE_REF.PRT models.
  11. Click Preview again to visualize the ejector pins.
    On each point of the multiple point features and on both reference models an ejector pin is previewed.
  12. Close the Ejector Pin dialog box with OK.
    The ejector pins and their according cutouts are assembled to the mold base.

     Note
    This ejector pin length is stored in the Parameter with the rule &remark to the model, by default this is the NOTE Parameter.
    Use the two configuration option EJP_NOTE_PRE_STRING and EJP_NOTE_POST_STRING to specify additional text for this NOTE Parameter before and after the number.
  13. Open the MOLD_VOL_ES_1.PRT model.
    All cut-outs are created on part level.
    The groups EJP_CB_ANGLE can be treated and handled like any other feature..

  14. Close MOLD_VOL_ES_1.PRT and return to the main assembly.
