Mould parting line

Hello hello,

 

What I like about challenges is discovering new functions. .and then, I dry completely. So I would need a little help (be careful, the copyright is registered ;) )

 

I created my shape, all rounded. This forces me to make a lower and upper mold with placement nipples and a chimney for the flow of the plaster. Unlike chocolate bars where a simple "shell" in the open air was enough. I created my joint line, insert drafts on the part.

In the mold itself, I manage to insert the core, recreate the joint line... But on the other hand, the parting line bothers me enormously: it is not complete (as you can see on the attached image).

 

Any ideas of why and how to get around it?

Sorry @ coin 37 coin

I don't understand anything and don't see anything in your image? ;-(

What do you mean you can't see the image? If you click on it, it doesn't show up?

Because I just tried, on my side and it works pretty well

As much for me, I didn't understand what you didn't understand (there's inception in the air!)

 

My parting line is the kind of incomplete circle/potato ... which should be complete! It's done automatically by following the joint line (which is well completed for the time being). And I can't understand why the plan doesn't close.

 

I attach my piece if it helps to see better. It's in Sldw2011, so I think everyone should be able to open it!

Look at these tutorials in English

but very easy to understand even for a Papuan ;-)

it's probably that you have very sharp angles

In itself, English doesn't bother me. But ... I don't have a sound card! It was obviously deemed useless by my group and I am therefore not entitled to it!

 

A path to dig for the acute angle

Cut your piece in 2 at the right of your parting line

no matter how you don't care since it's a symmetry

so your mold will have one side flat and the other the imprint of your part

Avoids all perpendicular faces for mold or part removal

You should never be vertical to the mold

Hello

In my opinion, the 2 parts of your fruit paw will be glued at the end. From memory the 2-part fruit legs are made like this, so no need for a complex mold but 2 simple molds.

But we would have to ask confirmation from @Clémentine

Hello

Do not hesitate to complete the parting line manually, add an additional surface and then a seam on the existing parting line. This is often the case, automatism cannot do everything, otherwise we would not be here...

Frankly a beginner in the thing ... I stupidly thought that we had no choice and that it was mandatory!

 

So I could create a surface plane that I like more, decide that it is my parting plane and continue like this without going through the Sldw function? Cool that

well here I am back forced to leave the PC  (emergency)

Look at this screenshot

The parting line is complete but it twists at a certain distance

 it tells me that you have a minimum radius curvature 0.000313574mm

That is to say that dal is therefore making a modification of your part

send me your piece if you want it

In the end, I really can't be good at it. I can't seem to create this damn parting line. So, I made half a fruit paste... which will be easier to put on the display anyway!
