Injection Molding Die- Part 1

[@DoMw4r]

If the drawing is perfect for you and contains everything YOU need to know to machine the part, then it's a perfect drawing. Don't sweat it big man, thank you for allowing us to be at your elbow for your craft, it is always a pleasure.

[@ilaril]

I love that you leave your errors in. I actually caught it before you started that you aren't in reverse! Now it didn't really help at all, but as I'm anything but a machinist, I'd say I've learned a thing or two from watching you, tot and cee. Always a joy to watch you do your magic!

[@ronnydowdy7432]

❤ Adam I use to make injection molds and believe me there is a lot of work that goes into making them the old school tool and die maker without any of the CNC or digital readouts that you have. We however did have optics on the milling machines. Some of those molds were very expensive to build and time consuming. The upper and lower halves had to match perfectly or you would have a very visible seem or line. Some of the larger ones were very heavy and could take as much as a year to complete.

[@jamesfranks545]

My son is a tool and die maker at an injection molding plant. They do most of their stuff with CNC machines. He works a lot with EDM wire machines and EDM electrodes. His main job nowadays is writing programs for the prototype molds for new customers. Basically, reverse engineering of a plastic part to come up with a mold to make that specific part. I find this stuff absolutely fascinating, and you sir are a credit to your trade.

[@neilmcgarry5784]

Another super helpful video Adam. I bought a bunch of hand ground HSS tooling from an estate sale a few years ago and there were two cutters in the pile made from round stock that I had no idea what they were for. The curved relief didn’t make sense to me… until today… and now I know what they are for.

[@Cancun771]

That dial indicator with the magnetic back is extremely handy, I've been making some special for my tiny hobby lathe and use them all the time. One of the best tricks I took from this channel ever. It is basically a super cheap Ersatz-DRO.

Injection molds are a whole new world of machining. The cost for say a single plate mold that will make 16 toothpaste caps per shot is upwards of $500,000 and a year plus wait list if you want another one. We had 7 presses and at any time, we had 10 to 15 million in mold inventory and we were specks in the game..

[@MadmanJimbo]

No, it’s not 500k for a toothpaste mold. Lol. Its 300k for a bumper/fascia mold for a car.

[@virginian7317]

@@MadmanJimbo toothpaste caps not the tubes, different process and yes I promise you that 2 ft x 3 ft 1 foot block of steel is about a half million bucks with tolerances beyond belief of hundreds of parts.

[@tonyn3123]

You should quit putting your drawings down. I seem to hear that a lot. i.e. "not perfect". I did mechanical hand drafting in college and much later learned CAD. For engineering drawings, there is a particular order to draw parts from an initial front view. Your drawings all seem to do that. The dimensions you need for fabrication are there. Your title block, while larger than normal, identifies the part, scale shown, sheet designation is there, author is well documented, etc. I even like the small 3-D insert add-in. Personally, I think your drawings are just fine.

[@ilaril]

I concur. When the drawing has just the info one needs to do their thing, it's a perfect drawing. Anything one doesn't need while machining is just possible error(s) waiting to happen.

[@plainnpretty]

I agree simple is the best

[@tsmartin]

Not saying Adam did anything wrong ... just presenting another way of doing the job. I would have not cut the bar into three pieces. Holding that .250" end cap in the chuck is going to be fun. I would have chucked the whole thing and made each part as needed starting with the center spacer and use that as a gauge for the registers on the end pieces. I find it easier to hit external dimensions than trying to bore them.

[@CatNolara]

Yeah, was thinking the same thing

[@johnscott2849]

Maybe he likes the challenge of doing it this way.

[@tates11]

Yes that's how most machinists would do it. Use the stock to hold onto then cut the machined part off with the sooper dooper band saw blade. This saves a lot of material over time. Whenever possible make the bores first then machine the external mating diameters to the fit you need. So much easier.

[@ICA17887]

Brilliant traditional turning work, thanks Adam.

[@arkansas1336]

Lol....In the 1960's I made those kind of drawings sitting at a drafting table, very time comsuming. Still have all the tools, table, machine, and scales (architectural, engineering and metric all used many times during my career) to do a job now. But ability(?) that is another question. I'm an old, old man but I hope I live long enough to see the USA go metric for everything. Jobs I built in metric were the easiest of all I built (and the employees had no issues with metric). America is way behind in "this side of life" and we shouldn't be! Thanks for a nice video!

[@sandy1653]

I really prefer Metric in general. My biggest problem with it is that I don't have the instinctual grasp of it like I do with imperial if that makes any sense. Like if someone tells me a part is 280mm I have to think about that for a second but if you say something is six and a half inches I know about what that is.

[@arkansas1336]

@@sandy1653...I understand. You will have to just think metric all the time and it'll come to you fast. I find myself in my woodworking shop converting imperial measurements into metric....and I've worked with measurements for 6+ decades on a daily basis (building cabinets, houses, subdivisions, roads, bridges, sewer treatment plants, airports, etc).

[@blackout7615]

Metric is for those who give up their constitutional rights.

[@ellieprice363]

Won’t happen and can’t happen for many reasons. For instance if square drives on mechanic sockets were suddenly changed to metric millions of ratchets, torque wrenches, extensions and pull bars would be useless for future socket production. Instead we have 6.35 = 1/4. 9.5 = 3/8. 12.7 = 1/2. 19 = 3/4 and 25.4 = 1.0.

[@arkansas1336]

The USA had mandated the nation to convert to metric by September 30, 1996. Only 9 states had all of the signs, etc. in storage ready to convert. My state was one of the nine. Constituents around the nation started a “hell no” campaign and we’re still in the dark ages. Those that oppose change missed those days when metric education was taught. Metric education only requires one day to learn!

[@marley589]

Face grooving. Always set the tool above center to give extra clearance on the outside.

[@marley589]

I would definitely have drilled out the bore before any finishing cuts. To hope the part does not move when drilling from solid is not a good idea. Do all the roughing before finishing any feature.

[@danmenes3143]

A mold with no draft? How is Justin going to get the part out?

[@10-4CodyWade]

Either the polyurethane will be flexible enough to remove, or he will soon be ordering a mold with some draft 😂

[@seabreezecoffeeroasters7994]

Depends if they are Nolathane (or similar) bushes then they will shrink off the mold (typically 1-3%) or you will likely be able to assist them out with air.

[@danmenes3143]

@@seabreezecoffeeroasters7994 If the bushes shrink, won't they bind up on the core?

[@seabreezecoffeeroasters7994]

@@danmenes3143 Shrinkage will tend toward the middle of the bush so in all dimensions. Without knowing the full setup of the final mold process some air to pop them free would still make sense to speed things up.

[@danmenes3143]

The only way I can see this working is if the bushing is cast around a tubular metal insert. Otherwise, if the bushing shrinks uniformly in all directions, the central hole will shrink by the same amount, and given how sticky urethane is, I think you will have a devil of a time knocking it off in one piece, even with compressed air. It's a different story if it's urethane foam. A low density foam would be compliant enough that you could probably get it off, assuming a good mold release.

I always like how good your tools look and cut. You always mention what model and number they are which is helpful. Could you also put in links to where we can buy them and you get affiliate referrals? That way we could see a tool or insert you use in a video, check your comments and buy it right then? Those of us new to machining can have trouble sifting through a lot of confusing sites. Keep up the good work!

[@BOBPortlandOr]

Side View, Front View, and Isometric View

[@marley589]

Often a plan view is also needed for parts that are not round. There are frequently two side elevations for round parts but you will need to know if it is first or third angle elevation.

[@JohnSmith-vi5pz]

Adam says ''20 thou to come off'' and winds the knob by 20 units. Does that not take 40 thou of the diameter? - it always confuses me no end.

[@evilsdevils]

that's because the units on the cross slide are 2x the actual movement, which is to say, it's graduated for diameter and affects the radius

[@cole4406]

Depends on the lathe

[@bigalhudson]

Never seen a lathe have anything but direct movement measurements on the manual increments on the hand wheels. DRO’s can be set to read diameter or radius.

This person is mostly likely a troll, but I'll bite anyway .. For machining the difference between metric and imperial is measuring in .01 mm or .001 in. I have yet to watch a machinist that doesn't say "use the system you have your machine tools in." Most KZbin machinists (not all, I get it) use both, and not just to appease the trolls. With CNC it does not matter at all. So, @numeprenume512, if you want to be intentionally controversial and try and rile up the "arrogant Americans" just understand most of the folks here know that and just don't give a damn.

Why tighten all three pinions on a 3 jaw with scroll?????????? See you do it all the time. One pinion turned tightens all three jaws equally.because of scroll. WHY???? Been a machinist 45 years and have never done it

[@brettbuck7362]

It centers the scroll in whatever slop there is for it to turn.

[@KodiakWoodchuck]

Sometimes there's slop between the pinion and the scroll. It takes 2 seconds and eliminates a potential concentricity error. So it seems worthwhile.

[@kindabluejazz]

Many years ago he showed how he got better repeatability when doing it that way. The scrolls aren't always perfectly milled and aligned. It depends a lot on the chuck, the brand the age etc. It's a good habit, and it can't hurt.

[@firesurfer]

There is backlash between the jaws. Especially as it gets older.

[@marley589]

Nor me, I have never seen it in real life, never done it and never had a part come loose. I just takes slack from the other 2 pinions. The scroll is already clamping the part.
