I want to learn about mold design from you, and I hope you can give me some pointers

Now it is still in the literacy stage, it is best to find some information on the Internet to understand what the mold is, and then find a few sets of molds on the forum to take a closer look, and then dismantle the parts of the diagram must be understood, this should also be found on the Internet, do not understand you can ask friends you know or ask for help on the forum, generally happy to help; The premise is to learn CAD and a 3D software (it is recommended to learn UG), CAD must be practiced with shortcut keys, so that you can first find a job as a draftsman or assistant engineer in the mold factory, and when you come into contact with the real mold design, you will be out of the school for two years, and when you have about 50 sets of mold design experience, you are already a more powerful mold design engineer!

I don't know if you have ever done a fitter, the processing and assembly of the general mold factory should not be in a workshop, since it is engaged in processing, the mold should see a lot, the mold structure is your advantage, look at the mold structure when processing, nothing to go to the mold assembly more turnaround. Remember that software is always secondary, take a little time to learn, our design department boss proe software will not but the design drawings are basically drawn by others, but others use software to process, field experience is very important, 3D demoulding is in your brain has a structure, how to choose the parting surface, how to give way... If you decide to do a mold design, leave a message...

It's free, I took too many detours when I was a newbie, and I understand your state during the confusion period!!

Mold design to have three or five years of fitter foundation, you do a number, you can develop to programming, the salary is also good, mold design is not more focused on the mold structure, rather than software... If there is anything you don't understand, you can also t mine. That's what I do.

It is recommended to go to the engineering department of the factory to provide learning systematically. Chang'an has a home Eagle Mould Company has provided learning in this area.

First, mold design and production is the aircraft carrier of industrial production, mold design in China is currently in the development stage, there is still a lot of development space and opportunities, that is to say, both the future and the money are very good.

Second, mold professional and skilled personnel are in short supply of skilled talents in the 21st century. According to reliable sources, at present, there is a shortage of 600,000 mold and CNC machining talents in China, so it is difficult to hire high salaries for mold skilled talents; The shortage of talents has become a bottleneck restricting the further improvement of China's mold technology level and the further development of the mold industry. The development of the industry brings insufficient supply of talents, and the reason why there will be "a monthly salary of 6,000 yuan is difficult to hire CNC technicians" and "an annual salary of 160,000 yuan can not recruit mold technicians" is mainly because China's current mold talent training can not meet the needs of the rapid development of the mold industry.

3. At present, many places such as Kunshan, Jiangsu, Shenzhen, Guangdong and other places have begun to establish mold industry cluster areas, and Shenzhen has become the country's largest mold design and manufacturing base, with more than 1,000 related enterprises and an annual output value of 10 billion yuan. At present, Shenzhen has accounted for 60% of the national mold output value, and the processing mode is novel and the method is advanced;

Fourth, since China's accession to the WTO, the global manufacturing industry has accelerated the transfer to China, China has become the world's industrial power, the Pearl River Delta dominated by light industry, especially Shenzhen, aviation, automobiles, electronics, machinery, plastics, hardware, toys and other industries occupy a large proportion in the country, these industries have a model department;

In recent years, the development momentum of the mold industry is very strong, and the mold is a bitter and sweet road.

You should be able to find it. It's just a technically difficult subject. Relatively speaking, there are certain requirements for mathematical thinking.

Mold design refers to the personnel engaged in the digital design of enterprise molds, including cavity molds and cold stamping dies, on the basis of traditional mold design, fully applying digital design tools, improving the quality of mold design, and shortening the mold design cycle.

I'll help people ask, and I'm studying in **.

Calculation of punching force.

The punching force is the pressure exerted by the punch on the sheet during the punching process, which varies with the depth at which the punch enters the material. Generally speaking, the punching force refers to the maximum value of the punching force, which is one of the important bases for selecting the press and designing the mold.

When punching with an ordinary flat edge die, the punching force f is generally calculated as follows:

f=kltτb

150kn type in f--- punching force.

l--- Length of punching perimeter.

t--- thickness of the material.

b--- material shear strength (b=260MPa) k--- coefficient (generally take k=.)

Automatic progressive die design process: 1. Punching two holes, 2. Cutting process: lapping waste, 3. Bending (stretching), 4. Cutting (finished parts).

NOTE In order to prevent getting stuck during bending (stretching), attach one 4 mm ejector pin to the die.

I'm learning 3D.,Also build a model or something, but it seems to be very different from yours.,Read what you said, I also hope that you can find a school to learn under the system, I definitely don't have a comprehensive system of training, a lot of professional terms or something, you don't understand, your own exploration is very tangled, you understand that it is a kind of happiness in your own research, I wish you to find it sooner.

It is best to study at a well-known school for a period of time. Then apply for a big company with a good family. will be of good help.

Being an apprentice in mold design is actually helping engineers to mark and draw drawings. There's a lot to learn.
