Displacements, core result

The Displacements, core result is created only if you have modeled a core, and the Perform core shift analysis option in the Fill analysis advanced options has been turned on.

It shows the deflections of the core during the filling and packing phases of the molding cycle. The default display shows the final deflections of the core at the time indicated in the top-right corner of the display. The magnitude of the displacements is exaggerated by the scale factor set in the plot properties (typically 10).

Using this result

The magnitude and distribution of pressures on the core vary considerably during filling and packing, therefore, the displacement of the core will also vary with time. These effects can be seen by animating the result using the Animation toolbar. The maximum value on the legend is the maximum displacement that occurred during the filling and/or packing phases.

By default, the result shows the net displacements throughout the core by means of the Animation plot type.

Things to look for

• Excessive core displacement during the filling phase, which can lead to problems such as unbalanced flow. Typically, the displacement of the core will be at its greatest at the end of the filling phase, and there will be some relaxation back to the original position during the packing phase.
• Excessive core displacement at the end of packing, leading to frozen-in variations in thickness in the part. These variations in thickness can lead to warpage of the part and a reduction in structural performance.
