Question 2: What does the major of mold design and manufacturing do? The specialty of mold design and manufacturing can literally be understood as an industry connected with manufacturing industry, and the items used in our life are as small as pots, bowls, scoops and pots; Cars, ships and planes are closely related to it. It's the school season again, and I believe many students majoring in mold design and manufacturing will embark on the road to study. When we choose the major of mold design and manufacturing, we are told that this major is a good choice. Some watch other students sign up and read with themselves; There are also some relatives or friends around who are engaged in this industry; No matter how we study this major, our starting line is the same! Because we have never been exposed to mold design and manufacturing before; As a first-line mold designer, I want to share my mental journey of studying this major with my classmates for your reference! University is the last step for us to enter the society. Many friends also say that graduation means unemployment! Although this statement is biased, it also shows to some extent that the employment pressure is great now, coupled with the mentality of being too high and too low, it is inevitable that you will not find a suitable job for a while! There are also many students who have graduated and are doing jobs unrelated to their majors. As our last stop in society, we must learn basic skills well and make full preparations for our future! During college, teachers have less time to attend classes, so we should manage ourselves. As a student majoring in mold design and manufacturing, how to learn? 1: When you come out to work, the theoretical knowledge in school is basically useless. At work, leaders look at the results, not the steps you want to work. Just skim the theoretical knowledge, but you are not required to know something about tolerance and cooperation.
Rote by rote, at least when you encounter this kind of problem, you should know that you have studied it, where you can find the answer you want! 2. Go to the school library as much as possible. Although different schools have different books and materials, on the whole, the library materials are still very rich. If you feel that the library materials are incomplete, you can go to some large regular bookstores. The books in the bookstore are not only full of information, but also have more new products. This is a rare place for free information. 3. Be sure to skillfully apply professional design software for mold design and manufacturing! Such as UG, pro\e, CAD, Soldworks and other drawing software; You are not required to be an all-rounder here, at least CAD is necessary, plus any other 3D drawing software. After mastering the two necessary mold softwares, other commonly used 3D softwares should at least use software to convert between drawings and documents. Software will be the weapon of our future work. Without this weapon, you will not be competent for your work. 4. There is no distinction between good and bad majors, and 360 lines will be the best. In this short 3-4 years of college study, please don't be playful and keep up with the joneses. In the limited time, whoever grasps the time will grasp the future opportunity; Please remember: "Opportunities are always reserved for those who are prepared". Don't complain about the fierce competition today. There must be competition for talents. Click the link to join the mold design exchange study group :jq.qq/? . _ wv = 1027 & amp； K=fSX8vL There is a large open class in the evening. You can join the group to find the address of the main lecture.
Question 3: What are the necessary skills for mold design and manufacturing? Personally, the design needs rich mechanical knowledge, such as metal materials, mechanical coordination, engineering mechanics, mechanical manufacturing and other knowledge. Manufacturing must have rich practical experience in machining and fitter assembly.
Question 4: What is the major of mold design and manufacturing? 10: Mold design and manufacturing is a part of machinery industry, and mold, fixture, measuring tool and cutter are the four major technological equipment. The major of mold design and manufacturing is a simple "mold", which is divided into two parts: mold design and mold manufacturing. If you study hard, you can engage in design, which is relatively hard to do and has a good employment prospect!
Question 5: What is mold design and manufacturing? Personally, the design needs rich mechanical knowledge as the foundation, such as metal materials, mechanical cooperation, engineering mechanics, mechanical manufacturing and other knowledge. Manufacturing must have rich practical experience in machining and fitter assembly.

Question 7: What is the main purpose of learning mold design and manufacturing? 4. Mould graduates with good jobs will generally work as teachers in automobile factories, motorcycle factories, mould factories, machinery factories, foundries, scientific research institutes and technical schools. Civil servants and Selected Graduates are in short supply.
Question 8: What do you know about mold design and manufacturing? Mainly study the structure of some molds and the machinery and software for manufacturing molds.
Mold design should learn the method and principle of mechanical drawing.
The software includes CAD and POR|E as the main design software, and several manufacturing software such as UG.
Mold machinery includes lathes, milling machines, planers, drilling machines, etc.
It mainly includes stamping process and die design, plastic compression process and die design, progressive die design, die CAD/CAM technology, cold extrusion technology, plastic molding CAE technology tolerance detection and technical measurement.
It also involves CAD drawing, PRO\E, MOLDFLOW, UG, SOLIDWORKS and other two-dimensional and three-dimensional drawing software.
There are also some basic courses such as surveying and mapping, engineering mechanics, ordinary polymer materials, mechanical principles, mechanical parts, material forming principles, metal cutting technology and other professional core courses and main practical links:
1. mechanical drawing,
2. Basis of mechanical design,
3. Engineering materials and heat treatment,
4. Numerical control technology,
5. Mold manufacturing technology,
6. Plastic mold technology and plastic mold design,
7. Stamping technology and stamping die design,
8. Plastic molding machinery,
9. mold CAD/CAM,
10. mold price estimation,
1 1. Machining practice,
12. locksmith skills training,
13. CNC machine tool operation training,
14. mold skills training,
15. Graduation practice (design), etc. , as well as the main characteristic courses and practical links of each school.
Mold processing direction: ① mold processing and production institutions; (2) NC programming of mould; ③ Three-dimensional design of the mould; ④ Three-dimensional design of product development. Other technical fields: production management, logistics management, equipment management, quality management, project management, product development, automobile industry, mechanical manufacturing technologist, numerical control engineer, etc. [1] Main courses: advanced mathematics, English, computer application, mechanical design foundation, mechanical manufacturing foundation, stamping process and mold design, plastic molding process and mold design, mold computer-aided design and manufacturing (CAD/CAM), mold numerical control processing technology, mold assembly and maintenance, mold rapid prototyping technology, internship, etc. As for how difficult it is, it is still relatively difficult. In contrast, if you want to increase the competitiveness of your future work, you have to learn English well (this is very important, you may have to deal with foreign companies, or work in foreign companies, and so on). ) And you should go into the lab as much as possible and do as much practical work as possible. After all, it is relatively hard to live on this in the future, but the major of mold design and manufacturing is listed as a national talent shortage major. Its graduates are hardly worried about finding a job. General graduates are engaged in production technology, management, marketing, or advanced CNC machine tool operation in manufacturing industry. The main flows of graduates are coastal special economic zones and inland special economic zones. The enterprise's evaluation of graduates is capable and willing to solve problems for you. Good luck! ! !
Question 9: What is the purpose of mold design and manufacture? As long as you want to mass-produce products, you need professionals in this major, but this major has high salaries and more low salaries.
Question 10: What's the difference between CNC technology and mold design and manufacturing? Specifically, mechatronics is a major integrating mechanics, electronics and automation.
Numerical control refers to digital control, which should focus on automation, such as CNC milling machines, CNC lathes and machining centers.
Mold specialty refers to the specialty related to mold design and manufacturing.
The content of mechatronics is relatively wide; CNC is more specialized in the operation of CNC equipment; Nowadays, numerical control technology is widely used in the professional manufacturing of molds.
Numerical control prospect:
After China's entry into WTO, with the rapid development of economy, China is gradually becoming a "world manufacturing center", and the numerical control rate has become one of the important indicators to measure the manufacturing technology level and economic strength of a country or enterprise (numerical control rate: the proportion of numerical control equipment in equipment ownership). At present, there is a serious shortage of talents in CNC programming, CNC machine tool operation and maintenance in China, making CNC technology one of the four major majors in China. There is a shortage of middle and senior technical talents, and its value naturally rises. Therefore, the graduates of this major have always been one of the most popular majors in the human resources market, with good working conditions and generous treatment.
Employment orientation: Students can find jobs in CNC machining technology and programming, CNC equipment operation and maintenance, CAD/CAM software application, CNC system or equipment sales, technical services, or workshop production management.
