180 SolidWorks Tutorial: Features Section in mold tools ; split line; draft; move face; scale Video Lecture | SolidWorks: Essential Training (All Commands included) - IT & Software

welcome to tutorial number 180 in this
tutorial we will talk about the feature
section as we see in the picture below
here or the section comes straight after
the analysis section as you might notice
this feature can be found in other
sections but there's a reason why they
are in this small tools sections because
they have some specific importance we
will talk about the split line feature
and then talk about the draft move phase
and then the scale and see how they are
related to the mold tools section in the
previous tutorial we performed a parting
line analysis for this cup and we took
the right plane as the direction of poll
and we got the parting line shown as we
see maybe in this case for this cup
maybe the best pole direction is the top
plane and that's why we will try to make
another example to see to run the
parting line and then talk about the
split line also we perform the split
line or parting line analysis on the
mobile cover and if we took the
direction of pole to be the right plane
as you notice click OK you didn't get
any line so that is clear that is that
right direction of pole or you cannot
for example mold this part in two
separated each half in one spirited part
of the mold so that's why again we run
the parting line analysis and pick the
two plane and once you have the part in
my analysis on your notes there is no
any
appearance or colors on the part so
let's start making a new part this time
we'll make a simple this and try to make
parting line and then how to use a split
line as helping tool here I will insert
four planes parallel to the top plane
and in each plane I will draw a circle
thirty on the second plane another
circle make it forty
and on plan number three another third
another circuit and give it a dimension
of 100
there again another circuit give it
dimension 60 and then the last circle
give a dimension of 75 and go to feature
bond repos are silly
you
so this is a simple vase plastic base
and for this kind of part because it is
curved it might not be possible to make
the direction of poi to be on the top
plane let's just hide the planes should
be difficult to extract this from one
side so this is your two more tools
parting line and if we pick the top
plane this shows that this part would
this complicity can be molded on three
parts because this slide to the left if
you separate it and that side by itself
can be easy to be ejected and extracted
and second side and so on
but this might be not logical and let's
try now to find a better solution
good parting line and this time select
the right plane and here we go a more
logical solution with one parting line
and we said that parting line represent
the line between the sides of the mold
here we can add appearance to this so
again go to the parting line and select
the right plane and here we got the
parting line
but you might need to not to work on the
parting line mood so you can deactivate
it and instead as we know that there is
the parting line is over there we can
make a sketch on the front plane and
draw a line matching the parting line
and accept and then we can go to the
split line and select the face which
will be this face and select projection
click ok so here you can deactivate the
parting line and you get the appearance
again by split line as a helping tool so
pair the split line you will get the
preview for so by performing the parting
line analysis we knew that the line over
there in the middle representing the
parting line and we made a sketch that
is matching that parting line to keep it
as a reference while working or to see
it without the need of activating all
the time the parting line analysis mode
we created a split line
and now let's talk about the next
feature it is also an important feature
in injection molding tools every part as
we see it in to make it easier to
extract should have a drop perform a
draft analysis for this phase and we'll
see what will happen
for example we will need a 3 degree
draft angle and here is the side of the
pole and you will notice that we have
kind of not logical combination here you
have the positive drop and then get the
negative drop and again you'll get a
positive drop this side might be very
difficult as we see it to be injected
with the direction of pole is the top
plane and we know we said that we made
the parting line on the right plane
let's go back to one of our part or the
mobile cover as you remember we add a
drop when we perform the draft analysis
and we added a draft and fix it all the
phases over there so it is important to
get a draw to make the part easier to
extract for example we can run drop
analysis let's make up our new part
let's extract a cylinder and perform a
draft analysis
here you'll notice that there are aside
that need a draft order to be easier to
be extracted so here are required drop
that why the draft feature is important
in injection molding tools so we can
make a drop pick draft and here the
neutral plane would like to be this
plane and face to draw this face click
OK and now let's perform the draft
analysis and pick this face and the
reference 0.5 click OK now here our part
is green so in order to make it a bigger
truck angle for some 3 degrees we can
edit the draft to make it 3 degree
triangle click OK and the draft you can
make inside or outside and let's run the
draft analysis pick this face and here
Air France to be 2 degrees and we have
our cup is green
and now let's talk about the next
feature they move fist we see it when we
are performing the parking line analysis
we get the the parting line for example
in this case is the edge and every we'd
like to expand this to make the parting
line showing or to make an offs for that
face we can use the move face feature
but in this case because this simple
cylinder or simple cup the parting line
will not be shown but we can try to use
the move face if we have the direction
of pull is the top plane and we would
like that 10 millimeter on the other
side to be molded and the other side of
the mold for example in the case of our
vests so let's first use the parting
line or the move face on this simple
part if we select the move face the
option which will be used is the offset
but the used in our mold tool case is
offset select this offset and we see a
10 millimeter and here we move that face
for example for some reason that we
would like the parking line to be on the
top plane and the part over the top
plane will be injected on the other side
of the mold this is only an example for
example we run the parting line analysis
and we pick the top plane here we not
see any parting line called elliptic
edge but with the help of split line we
can draw a sketch normal tool and make a
10 millimeter which is one the origin
split line and select the face and hear
how our spirit line and as we see it is
only an example we can try to use it
also on the face go to move face select
and we said let's make it 30 millimeter
try to use it on the mobile for example
we would like to extend the edge of this
face over here to be matching the
disclosed cylinders we can pick move
face and make it one millimeter click ok
but I will delete this feature for now
and we can solve it by adding another
edge or us not edge
so now let's move to the next feature
which is also other important feature
scale as we know that materials are
expanding with heat and shrink when they
become colder and also it is the case
with plastic injected molded plastic or
uninjected molded parts when they are
hot they are bigger in volume and when
they are getting colder they shrink that
why for example in this mobile if we
would like to have to inject this mobile
with the size shown in here we should
add in consideration that this plastic
part will change for example 5% for that
reason to solve this you need add a
scale you have many options but the most
use is the centroid it will scale and
here you pick uniform scaling and we
will make it 5% bigger it means one
point zero five so this is the part
which you need to design a mold for it
you
