The double-split type injection mold double-split surface injection mold has two parting surfaces. Compared with the single-part type surface injection mold, the double-split surface injection mold adds a partially movable intermediate plate in the fixed mold part (again It is called the active gate plate, which is provided with gates, runners and other parts and components needed for the fixed mold. Therefore, it is also called the three-plate type (moving template, intermediate plate, fixed template) injection mold, which is often used for spotting.

A single-cavity or multi-cavity injection mold for mouth feeding. When the mold is opened, the intermediate plate is separated from the fixed plate by a fixed distance on the fixed-column guide column, so that the pouring system aggregate is taken between the two templates. The double-part molding mold has a complicated structure, high manufacturing cost, and difficult processing of parts, and is generally not used for molding large or extra large plastic products. Right-angle injection molds Right-angle injection molds are only suitable for angle injection molding machines.

Unlike other injection molds, the direction of the feed is perpendicular to the direction of the mold opening and closing. His mainstream road is located on both sides of the moving and fixed mold parting surface, and its cross-sectional area is usually constant, which is different from the molds used in other injection molding machines. The end of the mainstream road is to prevent the injection molding machine. The nozzles and the inlet end of the main injection mold speed flow path are worn and deformed, and a replaceable flow channel insert can be provided.

In this regard, relevant experts pointed out that the technical competition in the plastic mold industry, especially Thin-wall injection molding manufacturers the technical competition of ultra-precision processing will undoubtedly influence the development and comprehensive competitiveness of the entire industry in the future. On the one hand, the miniaturization of parts and the improvement of precision requirements accelerate the company's desire for ultra-precision machining. Industry analysts pointed out that the plastic mold industry has entered the fast lane of development, and its development prospects are expected.High-precision chemical fiber mold future development direction

The future development direction of high-precision plastic molds Over the years, with the development of plastic-based steel, plastic-based wood and the increasing precision and complexity of product parts, the plastic mold industry has made great progress. On the other hand, behind the fierce market competition, the competition of its technical processes is quietly carried out. On the other hand, the development and maturity of related technologies have made the realization of ultra-precision machining possible. From the current development of the entire industry, although some technical applications have emerged, the overall application and development areas are still relatively limited, and it is urgent to accelerate the pace of development. It is reported that the plastic molded parts show its high precision, high complexity, high consistency, high productivity and low consumption. For domestic plastic mold enterprises, how to accelerate the mastery of technical equipment, especially ultra-precision processing technology is undoubtedly the most critical task and subject. As the technological level of the plastic mold industry continues to rise, the entire industry will also show a stronger development momentum. Unique value and important role.

The shape of the mold determines the shape of these products, and the quality and precision of the mold determines the quality of these products. Parts or products, this special tool is collectively referred to as the mold.Basic knowledge and technical application of plastic mold.The tools and products we use in our daily production and life range from the base of the machine tool to the outer casing of the machine.

In recent years, with the rapid development of the plastics industry and the continuous improvement of the strength and precision of general and engineering plastics, the application range of plastic products is also expanding, such as: household appliances, instrumentation, construction equipment, automobile industry, day In many fields, such as hardware, the proportion of plastic products is increasing rapidly.. A Plastic mould factory well-designed plastic part can often replace multiple traditional metal parts. Because of the different materials, appearance, specifications and uses of various products, the mold is divided into casting molds, forging dies, die-casting dies, stamping dies and other non-plastic molds, as well as plastic molds.

The trend of plasticization of industrial products and daily-use products is on the rise. The general definition of plastic molds: in industrial production, various types of presses and special tools mounted on the press are used to make metal or non-metal materials into the desired shape by pressure. It is small enough to have an embryo screw, a button and a shell of various household appliances, all of which have a close relationship with the mold

The CAD/CAM application software used in modern design and manufacturing technologies, such as object-oriented technology, integration technology, virtual manufacturing and Web-based collaborative design technology, and design and manufacturing as a whole, the integration of design and manufacturing information processing. Mold CAD/CAM is developed on the basis of the development China injection molding suppliers of mold CAD and mold CAM respectively. It is a new leap in the comprehensive application of computer technology in mold production. Mold CAD/CAM is the key technology to transform the traditional mold production method, and it is a high-tech and high-efficiency system work. It provides users with an effective auxiliary tool in the form of computer software, enabling technicians to design and optimize products, mold structures, forming processes, CNC machining and costs by means of computers.

The development status of mold CAD/CAM in China: Due to the increasing requirements for molds, the traditional mold making method can no longer meet the needs, which promotes the application of CAD/CAM technology in the mold industry. China's computer technology started late, and the development of mold CAD/CAM began in the late 1970s, but its development is also quite rapid. So far, CAD/CAM systems such as precision die, ordinary blanking die, roll forging die, hammer die and injection mold have been identified by relevant state departments, which play an important role in production and produce huge economic benefits. .

The main problems of China's mold CAD/CAM technology: 1, CAD / CAM integration is not high, still stay in the application of NC programming and drawing; 2, CAD / CAM hardware and software are dependent on imports, independent copyright software is very Less; 3, lack of technology and equipment strength. Application of CAD/CAM technology in injection mold: 1) Geometric shape of plastic products 2) Growth of cavity surface shape 3) Design of mold structure scheme 4) Selection of standard mold base 5) Generation of part assembly drawing and assembly drawing 6 ) Mechanical analysis 7) Generation of mold part drawings 8) Injection process conditions and injection mold material optimization 9) Injection flow and pressure holding process simulation 10) Cooling process analysis CAD/CAM technology in cold die: 1) Using geometry Modeling technology to complete complex mold geometry design 2) Completing process analysis and calculation, assisting forming process design 3) Establishing standard graphics library to improve design efficiency 4) Auxiliary to complete mold processing design and NC programming 5) Auxiliary to complete drawing work, output mold parts Figure and assembly diagram 6) Using computer to complete numerical counting such as finite element analysis and optimization design

In the previous article I wrote a common problem with stamping dies: mold failure. So here I will introduce you to this aspect of maintenance. The cost of stamping production is high. Usually the mold cost is 1/5-1/4 of the total cost of the part. This is because, in addition to the difficulty in manufacturing the mold and the high cost. The cost of mold repair and sharpening maintenance after putting into production is also high, and the original cost of the mold only accounts for about 40% of the total mold cost. Therefore, timely repair of the mold to prevent mold damage can greatly reduce the cost of stamping production. After the mold is damaged, there is a question of maintenance and scrapping. Generally speaking.

Unnatural wear of stamping dies, such as damage to non-critical parts. And the small punch is broken, the punch is thick and short, the concave template is cracked, and the cutting edge is cracked. Most of them can be restored to normal condition by repairing and re-commissioned into stamping production. but. When the key parts of the mold are seriously damaged, sometimes the convex and concave molds are damaged at the same time.The one-time repair cost Plastic Injection Molded Automotive Parts exceeds 70% of the original cost of the die, or the mold life is near. The meaning of maintenance is not great. At this time, the scrap mold should be considered: except for the large mold and the continuous mold with complicated structure.

When the mold repair technology is too complicated and the cost of mold repair is too large, the difficulty will inevitably make the maintenance period too long, which will seriously affect the normal production of stamping. It is necessary to choose to scrap the scrap beforehand and remanufacture the mold. Under normal conditions, the main failure mode of the die is excessive wear. Delivered from the manufacture of new molds. Until the burrs of the punched parts exceed the standard, the size and shape accuracy of the parts are too poor, and the mold can no longer be repaired or no repair value at all, the mold can only be scrapped. From the time the new mold is put into use to the end of the scrap. It usually takes many repairs and sharpening. I hope my summary is useful to everyone.

Continue to invest in technology, open mind to cope with new trends and changes in new features of external samples. 2. 3. 10, customer-centric, as a customer's partner, excellent customer service, a high degree of focus on developing and maintaining customer thinking, competitive price structure, delivery of the highest quality plastic mold components, fully in line with customer needs Keeping in sync and knowing how to use molded parts, this mold opening needs to be designed, the time frame of the entire project (not just mold manufacturing), reducing costs and innovating the entire design.

Through these points, I hope to give The industry brings some inspiration, the content is as follows: 1. Vision, there must be a short-term and long-term strategic plan, ask yourself, “How do we do, how do we do better?”, internal brainstorming session, discuss customer needs, start designing and Follow up on mold shipments, jump China injection molding suppliers out of the intrinsic mindset, and leverage the knowledge expertise of equipment suppliers and manufacturers. 9. Click to open the link 8. Flexibility must be able to adapt to the ever-changing mold market, even in adversity, embrace change, have a positive attitude, and change the technology to merge other plants in the most cost-effective manner

With the development of China's economy, China's molds need to increase, and the mold industry is also developing faster and faster. Next, I will introduce the industrial chain analysis of the mold. The main raw materials for injection molds are mold steel, mold blanks, mold parts, etc. The main raw materials for injection molded structural parts are chemical materials such as ABS and PC. The main raw materials for hardware structural parts are die-casting parts and profiles. Due to the wide applicability of mold products and structural parts, its downstream industry is very wide, including automotive, communications, home appliances, consumer electronics, aerospace, energy, building materials, machinery, information and many other industries. Currently, the issuer's customers are mainly concentrated in the automotive, communications, consumer electronics, home appliances and other industries. So what impact does other industries have on the mold industry chain? First, the impact of the upstream industry development on the industry: With the increasingly harsh working conditions of the mold, the requirements for the main raw material mold steel are higher, and the mold steel is required to have higher purity. Degree, better isotropic and uniformity, the development and development of new materials such as special mold steel will contribute to the development of the mold industry. The development of standardization of mold parts not only shortens the mold manufacturing cycle, but also improves mold quality and reduces mold manufacturing costs. Compared with self-made standard parts, the wide application of purchased standard parts can save man-hours and shorten the design and manufacturing cycle by 20%; usually, the standard parts produced by specialization will increase the matching precision and position accuracy by at least one order of magnitude compared with the self-made standard parts. Guarantee interchangeability, significantly improve the manufacturing precision and performance of the mold; at the same time lay the foundation for the application of modern technology such as mold CAD/CAM.

The application of hot runner products can significantly improve the production efficiency and quality of product production through molds, and significantly save raw materials and energy. The improvement of the performance of modern engineering plastic products such as ABS and PC and the research and development of new chemical products will expand the application space of injection molded structural parts and increase the demand of the industry. Second, the impact of the development precision mold manufacturing of the downstream industry on the industry:

The demand of the downstream industry determines the development of the mold industry. The downstream industries such as automobiles, communications, home appliances, consumer electronics, aerospace, energy, building materials, machinery, and information are actively affected by the national industrial policy. Support, the future development space is broad. Since 2009, China has become the world's largest producer and consumer of the automotive industry. The huge market space has attracted automakers to increase Ru0026D investment and continuously introduce new models, thus generating demand for automotive molds. China is the world
