Linear static analysis of plastic injection mold assembley

Hi Rahul

I am doing linear static analysis on a plastic injection mold assembly. Clamping force and constraints are as following

Pressure 54 MPa (This is the maximum pressure of molten plastic when it enters the cavity) is applied on core and cavity as shown below

The problem is that, the maximum displacement is much more than what it should be in real case (It is almost 10 times more). I have used SI units and I checked material properties, units look right.
I don't know understand why I get this result. I have used bolt connection, RBE2 and also FREEZE contact to define connection between parts.
 

I sent you the model via your Dropbox link. I appreciate if you can spend some time and check my model and let me know what is the problem and why the maximum displacement I got is much more than the reality.Thanks a lot.
