Help with creating a mold for plastic injection

[threetwothree]

Hey guys,

 

I'm currently doing an internship with a university in Mexico, and i don't want to be rude, but my boss is a dick and doesn't care at all about the project, but I do not want to go home to australia with nothing to show for my work. So, throughout the entire internship i've been teaching myself everything as my 'mentor' does nothing to help or teach me.

 

Anyway, I'm really struggling to find tutorials/or figure out how to use mastercam to create my mold. The tutorials I've found to be the best are (

)

but I can't figure out how to apply the knowledge to my design.

 

If anyone could help, I would hugely appreciate it!

 

I only have 3 weeks left here and it's been a huge waste of time if I have nothing to show for my time here

 

Thanks heaps guys

Joe

When you say "apply the knowledge" are you referring to machining it?

[threetwothree]

yes. I have no idea how to create the tool path to machine the mold!

YOU WONT TO MAKE SHOW ONLY ON MASTERCAM ,OR SET UP ON SOME MACHINE ????

I want to write a CNC code to machine this mold. The model you can see is what the finished product of the plastic injection mold will look like, so what i actually need is to create the mold of this part.

 

I think the problem is I cannot select edges on my model for some reason. I'm trying to research now if this is a software issue or something else I'm doing wrong

You need to give more information. What type of machine are you programming? Are you actually going to run the g-code?

[mirek1017]

WHAT MATERIAL ????

[mirek1017]

you can use this toolpath

He's on X7, he won't be able to open that.

hey guys, the more and more i read, including your post Bubbles regarding the machine, the more i realise my supervisor is a dick and doesn't care about this at all.

 

For example, I didn't even know what was information I needed to know.

 

I know it will be machined from aluminium (but i don't know what type)

I will find out all the machine details

Is there anything else I should ask?

 

I'm going now with a list of questions which I'm going to force him to answer.

 

Thanks heaps guys i really appreciate your help.

 

Also, master80 i will try to open your file, but is there any way you coudl save it as an earlier version of x7 so I can take a look at it?

 

Really SUPER appreciative thankyou guys

Is the drawing you posted the actual part or is that the mold?

[threetwothree]

He only speaks spanish, so it's difficult to commmunicate, but this is ALL the information I have...

 

Machine type:

Mill

3 axis

Uses Mach3 Software

 

Material Type:

Aluminium 1087 or 2024

 

G-code:

Yes we will run it

 

Drill bit:

Flat onventionl style drill bit (Diameter = 1.5875mm OR 1/16")

HSS Material

The drawing i posted is the actual part. I want to remove this shape from a solid block of material to create a mold

 

So the part i posted i want to make a mold for

THIS IS POST FOR HAAS ,AND THIS IS ONLY SAMPLE OF TOOLPATH

Do you have a proven post processor for the machine?

[threetwothree]

i just asked, he said no. it has Standard Code NC.. if you know what this is. He re-itterated to me MACH3 sofware

[#Rekd™]

With the information you have provided I would say completing this yourself is next to impossible.

[threetwothree]

cheers bubbles, i appreciate the feedback.

 

 

I've made a 3 part and 2 part mold in solid works, hopefully i'll be able to find someone else in the university more helpful.

 

I will let you guys know how i progress and if I need any other info, great board/forum to be on

 

Thanks again!

It's important to know the difference between a solid and surfaces. The part you have up there is not a solid, but instead is a bunch of surfaces. In order to drive toolpaths from it, you'll want to use the SOLIDS dropdown and select "from surfaces."

 

You'd also have to convert it to a solid in order to make a mold cavity from it.

Cheers Felis, you were correct even though I only just saw this!

 

OK so I have an update.

These are my MOLDS. I realise there are some areas which will not be possible to machine (for example all the edges, and some internal dimensions, due to the diameter of the drill bit), but at this stage I'm not worrying about it, I just want to create a tool path as best as possible, and if some sections cannot be created to the shown size (for example the thin cavity which goes around the whole mold in Bottom Mold v6 (Part1), it's not a problem. I only have a week to complete it so if I try to re-design now, i'm screwed

 

Thanks again for any input guys, can't stress anough how much i appreciate the community help
