Injection moulding screw tip

[Mr. Christoph Schmotz 0]

Hello everyone!

 

I am new to this software and now there are some difficulties I do not know how to solve.

I want to create a injection moulding screw tip like this one:https://www.arburg.com/fileadmin/redaktion/bilder/galerie_747px/12753_return_valve.jpg

The general cone already exists. I simply made it with PolyCurve and Surface of Revolution.

And now I want to "cut out" parts of it, so i can create the "wings". I also want this for the design study to generate a different number of "wings". Unfortunately I have no idea how to.

 

Thanks in advace!

Hey Christoph,

 

Can you attach your project file.

Then I can take a look at it and don't have to start from scratch.

 

 

Cheers,

Hello Karsten!

 

Of course, I seperated the tip for you in a single file. Hopfully, it is not complete nonsense I made.

The tip should be controlled by the opening angle gamma, the radius of the cap and the diameter D8 and D1.

And in the next step, there should be the "cut out".

 

Thanks for helping!

Hi Christoph,

 

I quickly set up a model using a Brep. There are other options, too. I actually did not put any effort into parameterizing the piece, I guess you have to do that yourself by setting parameters to the point locations that for the contour and the cutout.

 

here is the project file I created (I guess different dimensions to yours ...)

Best regards

I added a few parameters and dimension visualization. Have fun ..
