First off, this is my first attempt at using the mold tools.
I'am not understanding how to properly orient the parting surface.
Some hints or tricks would be appropriated
wonder the proper way to split the to faces that are at opposite drafts?
As Doug told you you got a draft isue, try this..
Having spent the first 15 years of my career as a mold designer, I can tell you that you often have to alter customers parts in order to make them mold-able...
Oh yea... And don't forget to ask if the part will have texture on it.
Hello Will,.. "if" you absolutely have to do it that way.. you can create a "insert" and either manually remove it (low volume) or figure a way to articulate it using a lift/slide? (image attached) (or... not shown,.. since your draft is about 7degs.. you could tilt the pull direction about 6 degs (you show a axis, maybe that is what you were thinking?).. and try shutoff and to pull it that way?
..otherwise,.. I agree with the others,.. if you reverse that draft and core it to reduce the wall thickness,.. that would help?
It's possible....but at that cases you could obtain some marks on the surface....
Thank you all for the excellent responses!
I was indeed envisioning something like what Paul did with the sliding Core.
know I'am thinking about the marks that would leave. I would still like to accomplish the part with the draft in the neg. direction,on the small cylinder.
So maybe my problem is more Not understanding the proper shut-off surface? and where to place the ruled surface?
I'll try a couple attempts and see what happens.
As you have the part currently modeled & drafted, you will need 2 slides...not just 1.
You are either going to have marks from "side actions" (which could be fairly clean) or marks from a parting line change / shut-off / draft change, which will get ugly... Unless there is a functional reason to have the draft that way, changing the draft is the best thing to do.
In the screen-shot below...
Green surfaces will be formed by the Cavity.
Blue surfaces will be formed by the Core.
Yellow & Magenta surfaces will be formed by slides.
Here's an option using 2 smaller slides with much shorter travel required. These slide move at 20 degrees to the right plane.
I see some tiny sections....modify it before you build that parts
Hi Ruben, If you mean the underside of the 2 slides ten yes. I stopped them at the edge of the radius because this is just to show another method, but the slides could and should extend down onto the tapered diameter a bit to strengthen that area if this method is used. see below. Better?
It looks better pal!
