injection moulding component

[Marco F inox]

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. .

In fact, my double arrow was left, instead of right, I just wanted to indicate the straight movement.
in front of these presses, at the right there is the fixed part with the injection, while on the left there is the plunger that pushes the table and closes the mold.
to determine which of the two parts of the mold, it must be fixed, it is necessary to establish the position of the injection hole, as convenient as possible.
the two shells of the mold, can then also reverse.

Then. .
the section of the post #23, this time by my mind, the mobile part is left.
said this I did not understand how the piece could remain in part mobile and not dragged into fixed part.
Regardless of all this and neglecting the major costs of the mold, I do not understand the advantage over an open and close.

As I have previously said, I have never designed injection moulds, I have only made dyeing and funnel moulds, but since I am not a pharmacist, with all the respect for the category, I consider the solutions proposed by fabietto and victorious the best as feasibility, simplicity and cost, moreover it seems to me is their daily work! If we want to prove that there are other possible solutions there is no doubt, but we must have the intellectual honesty to change my mind, as someone said, if in life sometimes it doesn't change ends up burning the clutch! :

ahahahah pietro this clutch is beautiful

Yes, of course.
by me the thread, from a certain post forward, took the tone of a comparison between designers, in love with their work, in front of a beer, in the post work. . .
a different exchange of ideas, where everyone can take advantage and cue, based on their experiences. .

I'm glad I made such an interesting discussion. I have read with pleasure your opinions, I am definitely a great enrichment for me.
the molder finally told me that with the equipment it has would be complicated to carry out this idea of mold and now we are considering a solution of alternative component. if I agree with the permission I also share the new project we are developing.
Thank you all!

would be a nice piece made from aluminum sheet, cost permitting.

I fully agree. for the type of piece that we would need would really be optimal to do it in sheet metal, only that our suppliers of sheet metal gave us as waiting times 8 + months, while others have really too high costs that the customer can not afford to pay unfortunately.

beyond all the molding problems, which in my opinion and others are overcome by tilting the piece, remains to be established the function of the particular. an embossed shelf, without any stiffening, by plastic, would flench and not by little, or you could break. I greet you all from the beach! ! !

who designs the piece, is not the molder but the client and if we want to contest it,
We wouldn't have the match.
if it has been asked to make plastic injection, with these measures and with this form,
It is useless to say that it is weak, that it bends or that it should be made of bending with other material.
you obviously did not see the application of this piece, the image was very clear
and it looked great, that is nothing but a small shelf, hooked to a cabinet,
of similar material.
All the more it will hold a paper rhyme, moreover it must be considered that it is removable, so you can rest on the table, imagine the difference between resting a plastic piece or
support a piece of sheet metal?
I'm at home and I'm glad to answer you, enjoy the sea, do some good diving, at least interesting
like the ones we do on this forum. hi and good holiday.

I do not agree at all, if it is true that it is the client who designs the particular is also true that those who know the technology to be used is not the customer, it is therefore a good professional to point out to the client that that piece as it was designed will not have the quality or technical characteristics to perform its function and in this case that piece printed in injection that comes out from the mold can not be the one he designed. if then once you have warned the client that that project when coming out of the mold will convert and will not have flat surfaces the hooks will close on themselves and the piece will be to throw if he will still be convinced then the address from another provider of problems in life they already have enough even without going out to look for them. for this it is better to ask the printer rather than the tool, he then with those molds will have to work with us. . .

I agree perfectly.
the first to be asked is the one who must produce the object ensuring the required characteristics.
will then be the printer that will interpel the trusted molder and together find the best solution.
otherwise not feasible not to advise the final customer, the technology he asked.
It usually works so
