cast iron casting piece

[folle76]

Hello.
We must make a piece similar to the annex obtained from cast iron. I have no experience about it, but I imagine that the piece I present is not at all feasible constructively. that I should use about rays, sforms and thicknesses?
Thank you for any kind of suggestion you can give me. for the undersigned will not be trivial at all!

In my opinion, it can be done so, but it would be easier if you reverse the deform (even 1-2° should be enough) and if you eliminate the rays at the bottom to simplify the plaque.

If I understand correctly, is it?

hi ing mad76
is an easy-to-invoice model
However, it is necessary to understand in which context is used together
If it's a counterweight without any need do as you want
sforms must be roughly 1/20 mm
if there are specific needs
the sez must predict these requirements
also you must keep in mind which part of the sez is cast in the lower bracket and which part in the upper bracket
where you can affix the castings and the fuselage technologgia including madness traps and various filters
if the prod numbers are low then you can build a model in nature with relative 1% for the griggies
0.7 for spheroids
according to standard the sforms should be to increase if not prog otherwise
Famme sape!!! !
Thank you very much

is an easy-to-invoice model

our suppliers easily invoice even the most difficult pieces. No problem.

If it's a counterweight without any need do as you want

It's a ballast. never absolute function was more ungrateful however the customer wants it even painted.

sforms must be roughly 1/20 mm

Huh? You make me count early in the morning... would be 1 mm every 20 mm? or an alpha=arctan angle(1/20) that is about 3° of deformity?

also you must keep in mind which part of the sez is cast in the lower bracket and which part in the upper bracket

is it not enough to echo in a mold just like pudding? see .pdf?

if the prod numbers are low then you can build a model in nature with relative 1% for the griggies
0.7 for spheroids

240 pieces of about 10-13 kg each. You still don't know...

according to standard the sforms should be to increase if not prog

! more than 3rd if it does not progress...remembered differently?

Thank you again!

Okay.
then plated with two models
I made two accounts the weight should be 20/22 kg
for two models 40-45 kg fusion
I attach a synthetic sketch
I wish you a good Sunday

Hi.
by pdf
you can also solve the prob according to the sketch you post
on the contrary you can also drain the piece of the open sky
But it's better to focus on quality
the price of cast iron does not change
It's just a matter of equipment.
that however big way costs the same
Thank you very much

Thank you very much.

That's very clear.

Hello mad76,
the shiren model I would say is correct. regarding the withdrawal of the normal grey cast iron up to 600 mm you have 1%. for the sforms depends both on the size of the model height and the type of model used (if in wood but not or in steel mechanical forming).

for mechanical forming, then steel model, with your size (h=75) you have a 1st scampanation (altitudes model from 51 to 80 mm) while with h=7 where there is the lowering you have the 3rd ripping (from 0 to 7 mm = 3°, from 8 to 20 mm 2°).

If necessary, they can be formed in pairs or with radial circular crown forming a ring where the casting channel is placed in the centre and on the outside one or two straights per element to compensate for the withdrawal. Of course it is necessary to make a proper sizing of the channels and reserve tanks, as well as the power channels.

If you do not particularly care about the upper surface, the one without step, you could do a spring casting with the two half brackets with volume greater in the upper one in order to slow the power of liquid cast iron and not use the materozzes but only the vent of the gases. However if you do not have to design the mold, I would say that this info is only additional but not essential.

for other info, mail as well.

That's very clear.
Hello everyone

Bye-bye
I see you have attached a rolleyes
if you have any doubts about the construction technique of its plating and fusion technology
you can ask no prob
We're here for this.
Thank you very much

(if in wood hand forming or in steel mechanical forming).

hi ing
I think I have already given
any written norm on the degrees to give to the corners of browse
has only an academic value
this applies to all industrial molding industry
who knows about molds must indicate how many mm of sform it needs to extract the piece from the mold without prob that it is a model for foundry or an injection mold blowing etc etc.

in the specific models both it in wood or other material
(steel is not used because in contact with the wetlands and foundry resins they oxidize
for jokes around a few million melted pieces maybe use extruded cast irons
from which to obtain models with technolog.cad-cam
in fact for strong beats are used non-ferrous metals or specific resins
with infinite series of density and hardness)
there is no difference in angle of sform
but all must be thought and studied according to demand of the foundry
diversifying the corners of a pattern is a delicate and
costly
to carry out it there is the need for staff living in the daily probes of the foundries
Thank you very much
