DRAFT ON SLIDE
DRAFT ON SLIDE
(OP)
Hello everybody. Another query.
Is the slide really nescessary to have drafts, I have feature
that fitting is critical so I don't plan to give a draft,
is this possible. please see attached.
Thanks for your inputs.

RE: DRAFT ON SLIDE
You appear to be trying to design the mold.
DON'T DO THAT.
Design the part you need, make a proper drawing of the part, with dimensions and tolerances, and talk to your molder about it. Annotate the part drawing to show where draft is acceptable, and where it is not, but don't assume that you know how the mold will be constructed, or how it will separate.
If the molder needs changes to your part drawing, he will ask for them.

RE: DRAFT ON SLIDE
If the illustration you provided is anywhere near to scale, the pins must be 10mm diameter, and the wall of the 'box' is at least 15mm thick. Which suggests that the walls will shrink away from the slide pins, so the pins don't even need a super nice finish. And you'll have a very long cycle time, or you'll have to fixture the parts as they cool to prevent distortion.

The problem with presenting grossly simplified geometry along with your question is that the simplification may distort the answer.

The ideas you share make a difference and move me forward on my design.
Many thanks.

I would add that to increase the chance of withdrawing the side cores succesfully, polishing in line of draw will help.
