Draft Angle Check

[Rastanking]

Hi everyone,

I'm quite new to ProE and am having a little trouble getting my head around a draft angle check when creating a mold. When I create a draft angle check I select the direction in which the mold would move to reveal the part but the draft angle check shows me different colours.

My question is this, in both parts of the mold the upper and lower surfaces are both magenta, is this the case for all molded parts or is this an error that needs correcting before the mold can work?

Thanks in advance

Andy

I'm trying to visualise how both parts can be the same colour.

Post a screenshot.

In the draft check dialog, select the angle you want to
check against. If everything ought to be at least 1
degree, select 1 degree.

The draft direction plane should be parallel to the
parting line, perpendicular to the direction the mold
opens.

The tool defaults to one direction, I always select two
directions (buttons next to the angle) because I want to
check both sides of the part.

To check the whole part in the surfaces to check pick the
part name at the top of the model tree.

The part will turn half blue and half magenta and the
division between the colors should be at your parting
line. If anything is any other color it's less than your
specified draft angle. I believe green means it's zero
draft.

Hi Doug,<br style="font-family: Arial,Helvetica,sans-serif;">

Being a novice at this I can only manage to open one at once, I have tried to post a screenshot so you can see what I mean but the site won't let me attach anything.<br style="font-family: Arial,Helvetica,sans-serif;">
<br style="font-family: Arial,Helvetica,sans-serif;">
If I set my part to have a draft angle of 2%, so that it can be ejected
from the mold easily, is this what the draft angle check is looking
for? If so I cannot work out why the top of the mold would be magenta,
ie above 2% since no draft is applied to the top.....I am confused!!<br style="font-family: Arial,Helvetica,sans-serif;">

I just noticed that WF5's draft check is different than
earlier versions. IN WF5 there is no pick for 1 sided or
2 sided, it looks like it does 2 sided by default. What
version are you using?

If you set the tool to 2 degrees it's checking for that
number. Anything 2 degrees or more will be one color
(blue in WF4, lavender in WF5), anything -2 or less will
be another (magenta in WF4 and salmon-ish in WF5). That
assumes you picked the two sided button on WF4 (double
arrow).

Anything underafted (zero) will be green in WF4, white in
WF5 and anything less than specified but more than zero
will be shaded based on the settings and how close to 2
degrees it is.

I'd make sure you picked your parting plane (direction)
correctly. It ought to be parallel to the parting plane
of the mold, perpendicular to the mold opening. Assuming
all that is right, I'd say Pro/E is telling you that your
geometry is drafted after all.

Hi Doug,

I'm using WF4 and my parting plane is perpendicular to the mold opening.

Another quick question, if I may, what is a 'test shot'? Is it, as I believe, carrying out a filling procedure in Plastic Advisor and from that you can get the shot volume and filling temperatures?

 

[dgs]

I'm not familiar with Plastic Adviser, never used it.

If you're confident that you've gotten everything set
right, then Pro/E believes the surfaces have sufficient
draft. You might cut some sections and measure to verify
it for your own peace of mind.

Thanks for your help Doug I will try that.
