MUD Base Plastic Mold Models

It doesn't seem DME publishes MUD base models.

Is there another source to keep me from drawing things up myself?

Many Thanks - Bo

But they have only a few accessory parts in their online listing.

 

look under the "Companion Insert Molds"

 

I see a short list of numbers, but no frames, and the buttons don't
work on the parts I clicked.

I don't think DME wants the info documented outside their shop.

Maybe I ought to put up the couple of MUD bases I have drawn up.

You can get MUD clones at Progressive. I think it's:
http://www.procomps.com

Look under Products for Unit Inserts.

Bo,

I can't figure out "WHY" anyone would be so obsessively secretive about
something you could measure and model so easily as a MUD frame. Some
companies internal policies are really stupid beyond belief. They even make
it difficult for you to design around their product by forcing you to go
through a ridiculous registration process before you can have the
"PRIVILEGE" of getting CAD data so you can make THEM money. Screw em !!!

If you want to see how a vendor web site should be go to Stock Drive
Products, or Bimba.

rant over,,,

It has nothing to do with "building your own" MUD Base. DME/MUD give
you enough information to copy a MUD base if you want to do that, but I
think it is cheaper to buy direct from DME. What I have done on prior
MUD bases I've used are modifying the frames so I can lay out custom
modifications like stripper plates and core retainer plates for using
ejector sleeves, and sometimes make custom mounting plates to mount
small MUD bases.

It is merely a starting point to analyze how to do a better custom mold
layout for my purposes, as a standard base won't do the job. By now I
have already created the stock MUD 16/21 UF321, and now modified it to
try to squeeze in what I have to live with.

I have a limited maximum die height in my JSW 110 = 15.7" and 16" clear
between the tie bars.
I need 4 inserts of a given size around 6" square to handle my range of
parts with their own cooling.
I need a specific ejection stroke and a stripper plate
I have parts requiring certain ejector & cavity plate thicknesses
I need to get cooling in better than the typical mold and not "run out
of space" in the cavity backup plates, and avoid or modify the bottom
of my custom base and avoid leader pins & tie bars
I want the cavity inserts sets to be self contained with their stripper
rings.
I want a custom leader pin setup so I can easily hold & slide plates
apart on leader pin extensions so I can more easily, safely, & quickly
change the inserts (because some of the plates are 300 pounds).

I don't really know whether I'll have a pseudo-MUD base or something
different made, but the "inside" has to be packaged first before I can
look further.

I need to know whether I can cram in what I need in a limited space
without making complexities which will drive the mold cost up. Once I
figure I know approximately where I am, I will have to take my jumble
of parts to a professional mold designer who REALLY knows production
molds and have him detail everything correctly, and tell me whether I
am nuts or OK on my assumptions.

The whole reason for doing inserts is we have lots of existing & new
part designs but not enough volume to do a dedicated mold for any one
of the parts, let alone all of them. If the volume ever rose, we would
look at deadicated molds (as we have for many parts). The insert mold
obviously makes it easier to try a new product as a side benefit, and
lots of the new product features can't be judged well enough from rapid
prototypes, when it comes to snap fits and deformations and such. We
still have to learn 'the hard way' in some things when we stretch the
limits of knowledge.

Yeah, actually, I think there are probably a half dozen companies doing
insert plate sets for MUD bases if not also copying their frames.

MUD frames and inserts are really a commodity at this point. If you
want nitrided, or stainless or aluminum you might buy from one company
or another, but they've all copied MUD.

PCS has cad data for their version of MUD bases. www.pcs-company.com

 

They do not go up beyond about 10x14 on base size, though.

Bo,
MUD used to make an electronic catalogue available. I have it here and its
is only 3D wire frame but even that is better than nothing.
If they won't give you a copy let me know and I will see if I can send you
one.

 

Yes, I've seen that and have it, thanks. Frankly, it is faster to just
read the pdf catalog and construct the solids in a sketch driven
assembly, so that everything in SolidWorks is related to the sketch (at
least at the start, until I break the relationships).

Later - Bo
