subframework

[volaff]

Good evening,
I wanted to search for information about subsquadro (other than the definition of wikipedia): How do I say a piece presents a possible subsquadro? ?
I read that you have to avoid the angles greater than 90° that do not allow the extraction of the piece but it is not that it is too clear.
Could someone explain me better or indicate some text/how I can refer to?
Thank you very much.

Hello, are we talking about sheet or plastic/metal presses?

a subframe is when the shape of the detail to be printed is such that it prevents the division and extraction from the cavity without damaging the particular itself
this is meant to us

in general I would say, more sheet and plastic molding

in case wrong seen the division line if I go to "open" the detail would split in two (and we are); in the case exact instead? the division line can't be the same otherwise I can't extract it the same or am I wrong?

 

[TECNOMODEL]

same division line, same opening direction.
wrong, the piece does not pull out, exact the piece is extracted.

but why should I throw in the cso b not be made at the base of the pseudo-agreement?

 

[TECNOMODEL]

look at the arrow of the opening direction and you will answer yourself.

I'm going a little confused honestly.
I don't understand.

let's see if it's clearImagine that the orange part is the steel of the mold.
in the left image, translating the piece in the direction of extraction you have a "dent" that does not allow to extract if not ruining the piece.
in the right image the problem is not there.

perfect.
Sorry about the "cooking"

would you recommend me some text to browse, but nothing challenging about molding in general?

I can't spend money

I hope to give you a hand with the following pictures:

in the image 'pezzo' see a hypothetical piece to be realized (trimetric view and section)
in the 'stampo' image see a very simplified hypothetical mold
in the third image 'subsquadro' see that the printed piece cannot be removed from the mold (mobile part) because of the subsquadro.

I hope I've been clear

Hi.

Thank you so much.
I understood (strangely); in this case there is that kind of hooking tooth that prevents the extraction of the piece from the mold; a nose the solutions are 2 sec me to solve the dilemma (but I throw them right for..)

1. avoid the tooth (if you can avoid it) and go the printed part to v without steps
2. divides the fixed part into two sub-parts and perhaps changes zone of extraction. type the mobile part is extracted from above, the fixed one from right and left

that proposed is an unrealizable piece with traditional molds, so the only solution is the first and that is to avoid the tooth.
particulars of this form are made with rotational molds (see for example the large flowers in the shape of 'orcio' of which I attach image).

 

[volaff]

I don't know how a rotational mold works so I trust... xd
Thank you very much
