Question 1: What is a mold? Mold is a kind of production tool, which can produce parts with certain shape and size requirements. That is, what people usually call molds, such as televisions, telephone casings, plastic barrels and other commodities, are produced by injecting plastic heating software into the molds and cooling them. The rice cooker is also pressed into this shape with a metal plate with a mold. Any commodity is made of molds. It can be said that there is no product production without mold. So how is the mold made? First of all, mold designer designed the mold structure according to the use requirements of products (parts) and drew the drawings. Then, according to the requirements of the drawings, technicians made each part on the mold through various mechanical processing (such as lathe, planer, milling machine, grinder, EDM and wire cutting), and then assembled and debugged it until the products could be produced. Therefore, mold workers need to master high and comprehensive knowledge and skills, so that molds can be done well and product quality can be improved. This factory is very profitable.

Question 2: What does mold mean? Simply tell you that the mold is used to ensure the quality and shape of the product in a certain production process. Accuracy, size, etc. In layman's terms, it is a "mold". With this mold, thousands of identical products can be made. Plastic products are plastic molds, hardware is metal molds, and so on. . Moulds are classified. There are dozens of uses. Ha ha. It can be said that mold is the mother of industry. I hope these explanations can help you.

Question 3: What kinds of molds are there? Runda Mould Factory tells you that stamping dies are divided into blanking dies, bending dies, drawing dies and compression dies. Machining metal plate.

Plastic mold: divided into pressing mold, injection mold, extrusion mold, blow mold and vacuum mold. Processing thermosetting plastics and thermoplastics.

Die casting mold: Die casting mold. Processing low melting point alloy.

Forging die: forging die. Machining metal.

Powder metallurgy mold: pressure forming mold. Machining metal powder.

Ceramic mold: pressure forming mold. Processing ceramic powder.

Rubber mold: divided into pressing mold, injection mold and extrusion mold. Processing rubber.

Glass mold: divided into compression mold and blow molding. Processing glass.

Casting mold: divided into sand mold, shell mold, lost wax mold, pressure casting mold and metal mold. Treating molten alloy.

Question 4: What is a mold? Professional molds are tools used to shape objects. This tool is composed of various parts, and different molds are composed of different parts.

Various molds and tools used in industrial production can obtain the required products through injection molding, blow molding, extrusion, die casting or forging, melting, stamping and stretching. In short, it mainly realizes the processing of the shape of the article through the change of the physical state of the molding material.

According to the different molding materials, molds can be divided into metal molds and non-metal molds. Metal molds are divided into: casting molds (non-ferrous metal die casting, steel castings) and forging molds; Non-metallic molds are divided into plastic molds and inorganic non-metallic molds. According to the different materials of the mold itself, the mold can be divided into sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Generally, plastic molds can be divided into injection molds, extrusion molds and gas-assisted molding molds.

Main course:

Question 5: What exactly is a mold? Actually, it's not your level, but is it necessary for you to learn? Can you program numerically? Processing center, is that all right? You don't want to learn mold when you master these things, because this step you have learned is talent! Besides, the mold is overcrowded now, and no one should never learn it. If you can't graduate in three or five years, it is still a question whether you can find a job after graduation. Experts are everywhere, really! I agree with your father!

Downstairs, the whole thing is a wish that the whole world is looking for a job. Do you know what level domestic mold designers can learn now? I don't understand reality. You think it's so easy to be the first black hand in the world. Unlike Japanese, China lacks technical communication. Innovative talents need to be cultivated, but China can't. Let's go out and have a look. There are many streets without jobs, including your so-called black hand. It's simple. Most bosses are determined and open-minded.

Question 6: What is a mold? What is a pair of molds? The development of mold industry in China is only about 50 years. Simply put, the mold is the mother of industry and the amplifier of economic benefits. From daily necessities to aerospace, transportation, electronics, transportation and other national industries, it is inseparable from molds. To put it simply, 90% of all kinds of articles we encounter and hear are produced and processed by molds. There are many kinds of molds, such as plastic molds, stamping molds, metal molds, powder metallurgy, casting and so on. The concept of width storage die is relatively general, but there must be several aspects, such as 1, independent process forming function 2, complete process forming process 3, and complete part taking-out mechanism. These are all important aspects.

Question 7: The slider is on the mold.

This is what Hong Kong people call it, which is mainly popular in the Pearl River Delta region.

The function is that the plastic mold cannot be ejected directly, and it moves horizontally or obliquely before opening the mold, so that the product can be ejected smoothly.

Question 8: What do you mean by commercial molds? Most of the pre-hardened plastic die steels developed in China in recent years are based on medium carbon steel with appropriate alloying elements, such as chromium, manganese, nickel, molybdenum and vanadium. In order to solve the cutting problem under high hardness, sulfur, calcium, lead, selenium and other elements are added to steel to improve the cutting performance, thus preparing free-cutting pre-hardened steel. Some pre-hardened steels can be nitrided after die processing, which can significantly improve the surface hardness and wear resistance of the die without reducing the hardness of the matrix.

Question 9: What does the mold look like? Mold is generally divided into six parts, depending on what kind of mold is different, it is generally six parts.

There are 1 plate, 2 plates, front die, back die, ejector plate and 6 plates (hereinafter referred to as bottom plate) in turn.

Some use a variety of materials, different iron or copper = =, but also processing, sanding, grinding, matching = =!

Very complicated, hehe, I just make molds and want to learn!

Just me! 370234850

Actually, I tell you, you don't understand. Only you know. Making molds is a bit tiring, and I have to work with different machines every day.

It takes about 1 month to make a set of molds. If the mold is broken, it needs maintenance!

Question 10: What is the mold used for? As a special mechanical product, the mold industry can't produce parts or mechanical products by developing and manufacturing mechanical products like other mechanical industries & mechanical products. Only through the designer's theoretical design can we basically ensure the required functions and use requirements that will be achieved in the end. That is to say, for most other mechanical products, if the processing technology can completely or as far as possible meet the design accuracy and requirements, the final product will not deviate too much from the original design purpose. That is to say, a perfect design can produce a perfect product under the guarantee of processing conditions. At the same time, the theoretical basis of the design of this kind of products, such as various machine tools and power equipment, has become very mature, perfect and practical after decades of continuous research in some old capitalist countries and even hundreds of years of non-development.

Mold products are different, because no matter injection molding, die casting, high-temperature flow molding or normal-temperature stamping plastic molding, although there are decades of research and application history, there are still great uncertainties because the basic theory and mathematical model are not perfect and accurate, especially in China, most of them still rely on the experience of on-site debugging to make the mold products as perfect as possible and the products produced meet the requirements of users, so at the design stage, most of them are at present. ! In other words, the quality of the mold usually depends on the technology of the fitter. The final confrontation of mold products from different manufacturers may be a fitter's skill contest. In this line, designers and pre-processors can only play a supporting role in the confrontation.

I don't know, I didn't say whether the majority of colleagues agree or not, but it is a fact. No matter how perfect the mold design is, no matter how good the drawings are, no matter how expensive the equipment is, at present, it is ultimately up to the die fitter to reflect the former's labor and wisdom. Without them, our design is probably a pile of scrap metal! ! !

In addition, at present, our research on remodeling structures, especially complex mechanical structures (such as various wedge-shaped linkage mechanisms in automobile molds) is not deep enough, and there is no technology or even patent that can lead the world. Some advanced and complex structures are mainly designed with reference to foreign precedents, and the level of independent research and development is relatively weak. On the contrary, assemblers may be better at reassembling and debugging these mechanisms than abroad.

As mentioned above, the imperfect plastic forming theory and mathematical modeling lead to the imperfect analysis and formulation of stamping process in the design stage, which requires a lot of debugging in the later stage of fitter. There may not be an immediate solution to this problem for the time being, and designers have reason to appropriately shirk their responsibilities. However, the mechanical structure of the mold is not good, and we seem a little sorry for this "hard injury". Of course, I think this is also caused by many reasons.

First of all, the relatively high-end mold mechanical structure is usually only used for more complicated parts and processes, such as the pressing of side plates, fenders and hoods of automobiles. Because most domestic automobile manufacturers are Sino-foreign joint ventures and other reasons, it is difficult for domestic mold enterprises to manufacture molds for such products, and they rarely talk about similar parts of brand-new models, so our actual combat opportunities are few. Some powerful manufacturers may have carried out practical theoretical design in production tasks. Finally,!

Second, even in this difficult opportunity, most manufacturers may search for foreign original drawings and then design them. The final mechanical structure may be improved, become a mold product with China characteristics, or even exported to these countries, but in the end it is difficult to really put the "Made in China" brand, foreign drawings and China steel together, and they are not worried, hehe.

Therefore, our mold industry, whether from design, research and development or machining, has inherent defects of lack of originality and independent technology. The only innate advantage may be that the skills of die fitters evolved from the superb skills of our ancestors. On that day, the world die fitter competition was held, and the voice of our players to win the championship may be higher than that of * * * to step down. Use me in the first battle and win with me! !
