difficulty designing parts obtained by molding (pressofusion)

[opua]

hi, for some time now I started working at a company that produces details obtained by die casting. Since I am a bit fasting on how an object can be designed and built that will have to be made with moulds (so not directly by processing machine tools), I can not manage to orient myself well on the design part, how to organize me in reference to the amount of molds necessary for the realization of the components and how to place them.
I heard that the criteria for die casting should be similar to those for plastic components, is it true?
Can someone please provide me with help, perhaps by pointing out teaching texts or online material that might help me?
thanks in advance

to design molds for both plastic or die casting is necessary
a lot of experience (as for many things), is seen the cost of the molds
and any delays you could generate I strongly disagree
to improvise you. if you're a student trying to do some research on the net,
or buy dedicated volumes (I know those distributed by new techniques)
or if you find alongside one with experience.:finger:

Hi.
in moulding
criteria are always the same
punch - matrix - possible male-(third movement)
injection-cooling or heating-extraction and equipment
mechanical fixing to the press
then and of course you have to adapt to the type of materials you have to use
if you have a moment of time in the specific forum there are a number of discussions
where you might already have half an idea

I invite you to attach a sketch - a drawing - or anything else you enlighten us about what you need prog.
we are here to help
Thank you very much

First of all, thank you very much to all, my work is not to design molds but, components that will have to be made by die casting and therefore, in the design phase be designed for the manufacture by die.
the difficulty consists in designing them thinking about how the molds will have to be arranged and how many they will need to realize it and, then insert the sforms in the right areas etc...

Hello opua

I do your own job (plastic - die casting al) : to design a piece or reindustrialize it to make it printable there are some rules to follow are not many but you have to understand "how it works" and at first it is not so simple

I don't know if there are texts to be consulted, but I recommend you above all in the phase when you are setting up the project with the help of the designer molds better if inside the same company and browse among the projects/prints currently in production maybe looking at them when they are disassembled obviously if you were alongside a senior designer ask him more (with the hope that it is a type available)

all in being able to imagine (and sometimes to determine) how the mold will be made: where there will be closures and then set the sforms

If you have any specific case to offer us from what I see we will be in many ways to help you

 

[opua]

thank you very much to all for the advice and availability to provide help:smile:

hello to everyone, I join this post to ask for information about plastic components ..
I found myself in discordance with a colleague who tells me that plastic compoents even if there is math have to be put on the table with all odds, while I am of the idea that if the moldist works with the mathematicians some get all the quotas from them ... I'm wrong in affirming the above?

 

[robcrac]

generally the design of the particular serves only for the dimensional control of the printed particular (reports therefore only the quotas subject to tolerance), and possibly to indicate everything that cannot be indicated on the model 3d (goffratures etc.)

Hi.

ahahah:biggrin:
I know what you're gonna say.
I have never made molds or parts from molding/casting. . I have just a school infarination (now almost forgotten:frown. and for these old reminences "the heart" would tend to give you reason.
probably depends on the type of object (engineering/industrialization) and the company that does the job to you. in many fields and reality it is definitely communicated only with mathematicians, but at the same time I am convinced that many moldists would "express" them directly the 2d tables (and I had experience even if not directly) while having all the technology to do without it.
However, I do not have the proper preparation to be able to respond in a certain way.

I understand the user who asks the question; is young and "turned to the future", would like to solve quickly by jumping all the classic, heavy and boring part of the design as you could do quietly. . but it is so, if they want that you have to do, and unfortunately s'ha da poor:wink:

I think the question is not complete

if you're talking about the finished or printed piece
this needs to have a dimensional testing
if you don't have a table with words and tolerances as you do to understand
if in the construction of the mold the sum of dimensional errors make
the piece acceptable by testing

if you refer to the mold
to make a mold you need prog/stampo
you need a drawing of a paper with a lot of distinct materials that big way you buy! ! ! !
and to buy or define commercial evaluations you need their size
if you have a prog with the due attributes verified and already proven
you can salt all phase
and also consider that to make the mold you can hang to build the mold in any off.mecc that has a turning and grinding centre
because the expert prog advises him what and how to do
if we do not have all this experience
make all the masses at the necessary table
with quotas and quotas without leaving any doubt to the performer
and turn to a moldist

to respond to friends users who seem to be healthy "dilegated"
here there is no philosophy that I keep you have to say how to do
I wish you a great weekend
that seems to be wet
:smile::smile:

 

[matteo84]

hello thanks for the answers,

In fact I do not design the mold but the finished piece I want to realize, my question is not for lack of will, but for lack of experience since I have no collaborator "old school" in technical office .
The moldist I work with, accepts the mathematicians, but sometimes I have to send drawings for supply requests (also abroad) and my correspondents, who are not technicians, require me in addition to mathematics also a drawing with quotas.

we shiren, we do not change the cards at the table... :smile:
I in that thread challenged you your association between the supposed ability to design with doing it in 2d and argued that today, fortunately, you can design in 3d.
if then someone still wants the tables 2d faiglie as well, but get automatically from the 3d and quote as you must.
the rest are nostalgies of the good times gone that nothing has to do with the passage from 2d to 3d but only with the time that, ahinoi, passes inexorable.

Hi.

 

[maxopus]

Aspè aspè, I'm seeing her all'sta robba.... (the old age you want to do).
We don't get drunk, but I'm coming from your side, and we're in a beautiful magnata and mozzarella.

When I said in the other discussion that the 3d could replace the 2d I did not mean that it is already so, today the 2d is indispensable.
and this because a standard of transmission of metadata linked to object 3d has not yet been implemented.
by metadata I mean all those data that are not represented by geometry but which have a descriptive representation

an example: if a part has some mechanically worked areas, how do I communicate it to the workshop with the 3d?
If a part is made of spheroidal cast iron, how do I transmit the information in data 3d?

and go ..... at least 15 information of this kind.

when a standard of communication between the various design systems will be established and will be realized .... only then can we think of abandoning the 2d ... and this decision, given the globbbalization , it must be supranational, because it would be useless to use this method in Italy and another when you have to work with Europe or another when you work with them or with wool.

This is for the moment, dear enzo but 'sta magnata' and muzzarelle quanne cia' facimme. :biggrin::biggrin:

we put on some ideas all together including those who accuse me of manipulating
