Hi ,while i'm trying to create a core and cavity for pen like structure, but while i'm trying to shut off the surfaces for one of the hole, i'm getting an error.
The error is show in the below image, please check that and help me out.
Hide the curves, clear the edge selection list, and manually select the edges where Shut-Off Surfaces are needed.
Hi Doug Seibel,
Thanks for the reply, I have tried the way you have suggested but it is still getting the same issue.
See the below images, In the first image i have selected all the edges to be shut off except the highlighted hole,
In the second image, after selected that edges all the other edges also becoming loop redundant.
If you want i will send you the model.
Unselect the problem area and let the system create the shut-off surfaces for the rest of the part. Then create a new shut-off surface feature just for the problem area, and if it still does not work then just use planer, filled, or boundry surface tools instead. When creating the shut-off & mold parting line surfaces you are not limited to only the "mold tools".
Or another way to put it mold tools are pretty limiting when used as the principle mould design tool.
The only "Mold Tools" that I am always using are Scale and Parting Lines. After I have scaled the part up for shrinkage and I've used the Parting Lines tool to separate the part into cavity-side surfaces and core-side surfaces, I generally create all of my shut-off and parting line surfaces using the Surface tools in Solidworks. The surface creation tools in the "Mold Tools" fail to give me enough control over the creation of the surfaces, and usually what they create is junk.
Doug yes the parting surfaces are well OK for sales tool really how I see it. The reality of having decent surfaces with minimal sparking is a whole different world. Obviously the shut-off (shuts outs as we call them in the UK) you will only get what you want if you do it yourself.
Scale and parting lines like you say are the most important.
TBH sounds like you are doing exactly the same as me. I guess most people will go down this avenue once they start doing tool design regularly.
Richard Gergely & Doug seibel i have used the surfaced to fill that hole , but it is effecting while using tool-spit,
There may be few reasons to fail the tooling split
Can you post the part here, so that someone can look into the actual issue?
For the inside hole feature, you may need an action to pull the core.
Please find the model in the above link, its has saved in 2016 Solid works.
How big is that file?, Why can't you post here (use advanced editor and attach)
ok, i dn't have idea about this process, so i attached the link.
Thank you , here is the file attached.
If you analysis the geometry, these are knife edges and doesn't allow to create the shut-off surfaces using mold tools.
You may want to create own shut-off surface using surface tools and try creating the split
I have tried my best to make core & cavity for this, i'm not getting it ,can anyone help out by creating core & cavity for the above attached model.
If I get time I will have a look but it probably won't be today plus I still need to load 2016 on.
On a side note. Where John shows the knife edge how are you intending to be able to pull those cores out on the tool?
Also exactly how small is the core diameter and length that runs up the entire body?
I modified the knife edge by reducing the pocket size (by 0.01MM) and now you could create the shut-off surfaces.
Here is the split, but if this is going to be designed like actual mold, you need multiple actions/different orientations (for the inside hole and the angular slots)
Hope this helps
