How to simulate the metal pin deflection in the connector part

[qyhgreen]

The metal pin deflection in the connector part comes from two source.

1. Before being ejected from the injection mold.

    the metal pin is fixed by the injection mold,

   the pin deflection is caused by the injection pressure,

which we can simulate by setting the metal pin as core and conducting the core shift analysis.

2. After being ejected from the injection mold.

    the metal pin will deflect freely following the plastic part shrinkage,

which perhaps we cannot simulate.

How can we simulate accurately the metal pin deflection?

Thanks a lot in advance

Hi qyhgreen,

Yes we can simulate metal pins, first prepare metal pins as a part inserts then according to tooling define constrains. As guess tooling for your connector & suggested constrained area refer attached image.

Thanks & Best Regards

Thanks for Halasur' s reply.

Yes, We can simulate  the metal pin's deflection when the metal pin is in the mold.

But I want to get the metal pin's deflection of the whole cycle,

inculding before being ejected and after being ejected from the injection mold.

Hello qyhgreen,

if I understand you correctly, as long as you use a 3D mesh for the part, and the pins are defined as "Part Insert (3D)", the warpage simulation will take them into account.

Also, you may need to play with the advanced options to perform a core shift analysis during both filling and packing, see attached picture.

Lastly I would recommend to use TET10 for the core shift analysis.

Hi qyhgreen,

Metal pin’s deflection for whole cycle (Fill + Pack) you can find, but it shows deflection only for fill + pack not for cooling cycle. Even after ejection deflection will be there but it is very negligible.

Thanks for EduardoCalle and Halasur's great help.

I will try to conduct the analysis according to your suggestion.
