injection moulding component

[Fabietto]

Good.
to close the whole circle it takes an image of the particular engineered, and one of the particular printed, with relative observations. .
of course if possible to publish. .

 

[ET3D]

I can try, but I don't promise anything, I obviously have to ask my superiors permission anyway that if by mistake it turns out that I didn't warn it ends badly. .

Thank you very much to all for your answers, I have been really helpful.
to update on the processing at the end I heard the molder who gave me directions on how to fix the piece to print it.

to completion of what I proposed above, I send a sketch on the possible operation of the molding, with slip for the subsquadro.
in the opening then, the right mold already acts in part as an extractor. Bye.

I couldn't ask for better. very clear and explanatory. Thank you very much rotten!

but just for.. the subsquadro in punzone (right side of your design) how do you remove it? if the piece remains left (matrix) you have to make a closed mold movement before opening the mold.. otherwise in mold opening the piece remains to dx (punzone) and you have to make a movement in extraction to pull out the flank in extraction. . .

ciao @marco f inoxI add to the comments already made on the subsquadro.
the only way to print this item is how it had already suggested @face, rotate the piece of 10° ... with the due other modifications on the wounds and other changes to ensure that the fusion remains on the mold part mobile

@vittori e @face 10° want to say wall to the vertical left I had proposed 12 ° to stay wide.

You're perfectly right, I was just focused on the rotation concept of the piece.
then there would be other changes that we might discuss when @et3d will post the final piece.

print with the vertical sx side as from your figure, you delete the big subsquadri.
remain the subsquadri of the 4 suns on the bottom, but they are easily overcome by milling vertically the 4 short sides, which would not allow the extraction.
However, when designing an injection mould, difficulties must also be taken into account
that you can meet in machine tool processing.
for this reason, but also because it can be an extra information, worthy of discussion, I proposed the sled, very used in many molds.
rereading my previous one, you also have the answer to the two red arrows. Bye.

 

[Vittorio]

ciao @marco f inoxI think we could go on infinity.
each of us speaks according to the experiences lived.
the solution to rotate the fusion, it seems to me the most practical and the least expensive to build the mold.
the function of the piece we do not know it, maybe it enters the wall and no one sees any imperfections.
In any case, all that moves is intended to leave traces on the piece, perhaps difficult to eliminate.
That said, every proposed idea is always constructive and brings value to discussions.

 

[Fabietto]

ciao @marco f inox, of course you have proposed an alternative, but you have to put a slide even in part mobile, if you want to extract the particular. (this was the sense of red arrows (right) @vittori? )

from this passage:
"rereading my previous one, you also have the answer to the two red arrows. "
instead I couldn't find the answer you indicate for red arrows.

and the detail, in the mold opening, remains on the mobile side, and not where you drew it.
then the discourse to rotate the piece came from the request of et3d to have a mold open and close.
Hi.

Hi.

you have to imagine closing the mold already mounted on the machine, axial translation, without the printed piece.
from the drawing you can understand that there are no interference, despite the subsquadro, because the sled advances following the entrance of the plug.
when the piece is printed, it is true that in the opening, the right part if it takes it behind hooking it in the subsquadro, (red arrows), but at the same time, the sled frees it, therefore also here there is no interference.
this sleigh carries out its task egregiously, as it is important to know,
the inclination of the plug ensures a displacement not lower than the subframe.
it is pleasant to hear your opinions and to discuss it, for many will also be new things,
but for me I am a great resumption of all the problems I have encountered throughout my working life. Hello, everyone.

but therefore according to you, in the opening mold, the punch deforms the side of the detail? Otherwise I can't figure out how you do to remove the inner subframe of the flank. .@vittori _ did you understand how to do that?

 

[Vittorio]

Forgive me @marco f inoxbut how can you think of removing this subsquadra without a further mechanical movement inside?
with a deformation I don't think so.. to the maximum I give you 0.5° subsquadro (but maybe too many) in this case are 10°

Of course you can do everything, but it doesn't seem like an economic solution

You like to win easy victorious! You're a moustache mold designer.

. I thank you pietro, but there is nothing for granted and there is always to learn.

only solution would be to make the inclined extraction of 10°, feasible and already done things, but this does not seem to me the case. .

you tried to reverse the sled and the plug, but see that the result doesn't change.
if the 4 short sides of the suns of those 10 12 degrees are tilted,
you can see that the piece has no constraint, it can parade and fall on its own.
then if it wasn't, there can always be extractors, but we never talked about.

 

[Vittorio]

Oh. I'm not convinced, but I see you so convinced that tomorrow they're still playing us.
you confirm that the image of your post #23 is the mold mounted on the press and the left side is the mobile part with the extractors?

 

[Fabietto]

hello and good day.
from how I am accustomed to seeing drawn the axioms molds, to post #23, I see the mobile part on the right.. this by my mental form, and by the drawn arrow that gives the idea that it is the part to move.
said this, I think I understand that, since the detail:
- has no ribbing or element that must be guided according to extraction,
- has a "passing" geometry, from high to low mold,
Good @marco f inox He wants it.
- send the piece by fall
- to the most use expellers, (in this case the piece during extraction will move a little because of the tilted flank)
and the piece will go by fall, or taken from the hand.@vittori referring to your section, if you get the matrice wounds, just push you a little more than the piece thickness, the piece in this phase moves right and falls.

personally, they are not solutions that are acceptable to me, and not applicable in my sector (eesthetic automotives), but I can understand that in some cases they are functional (always you don't stay a piece in the mold and call the press. . )

another solution, to get out of the solution of rotten, is that the extraction is not carried out, but the hand of grip, once taken the piece directly in punch, make a tilted retraction of 10°..
I don't know about you, but in almost 30 years of molds, I hardly saw molds with similar solutions between them...

I'll leave you. Good job.
That's Friday. .
