Structure, principle, and usage method of water tightness detection device for hot forming molds

In the production process of hot formed products, the mold needs to be continuously water-cooled to ensure that the mechanical properties of the parts meet the requirements during continuous production. The pressure, flow rate, and flow rate of cooling water inside the mold have a direct impact on production efficiency and quality. To ensure the quality of the products produced, the water tightness of the mold must be effectively ensured, and the flow rate and flow rate in the water circulation system need to be monitored. Therefore, it is necessary to test the sealing of the mold water channel during the mold assembly process.

Seven precautions in the design process of stretching molds

Because there are too many factors to consider in the design of a stretching die, such as the drawing coefficient, whether the material limit is reached, the determination of spring force, the direction of stretching, whether it is upward or downward, often cannot be formed in one go. It requires multiple trials to achieve the desired results, and sometimes there is a possibility of the die being scrapped. Therefore, in practice, we constantly accumulate experience, It is very helpful for the design of the drawing die.

Construction and advantages of cloud manufacturing collaborative service model platform in the mold industry

By analyzing the characteristics of the mold parts production industry, it is pointed out that due to the lack of sharing and coordination of manufacturing resources and the shortcomings of manufacturing models, it is difficult for the mold industry to achieve further balanced development. In response to this problem, based on the current collaborative manufacturing model and the development of cloud manufacturing, a cloud manufacturing collaborative service mode platform for the mold industry is proposed. The platform's architecture, basic principles, and key technologies are analyzed, Through case analysis, this platform can promote more reasonable resource allocation and higher utilization rate, enabling mold enterprises to receive professional technical and productive services, thereby improving the competitiveness of mold enterprises.

Briefly analyze the process points of wire cutting machining molds

Wire cutting is the main processing method for stamping die parts, but conducting reasonable process analysis and correctly calculating the design wire trajectory of electrode wires in CNC programming is related to the machining accuracy of the mold. Improving the cutting process by determining threading holes and optimizing cutting routes is an effective and important way to improve cutting quality and production efficiency.

Process Design of Trimming Mold

Stamping mold is a special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). The mold installed on the press is used to apply pressure to the material, causing it to separate or deform plastic, thus obtaining the required parts as a pressure processing method.

Standards for mirror polishing of molds, methods and precautions for mold polishing

To avoid scratching and burning the surface of the workpiece, special care must be taken when polishing with # 1200 and # 1500 sandpaper. Therefore, it is necessary to load a light load and use a two-step polishing method to polish the surface. When polishing with each type of sandpaper, polishing should be carried out twice in two different directions, with each rotation of 45 ° -90 ° between the two directions.

Steel and Heat Treatment for Hot Extrusion Dies and Medium and Small Machine Forging Dies

When the hot extrusion die is working, it is subjected to compressive stress, bending stress, and tensile stress during demolding. The impact load received is smaller than that of a hammer forging die, but the contact time with hot metal is longer than that of a hammer forging die. The working temperature is higher than that of a hammer forging die, and the temperature rise varies when squeezing different metals, with a maximum of 800-85090. The thermal stress caused by rapid cooling and heating is also greater than that of hammer forging dies, and the friction is also more severe. The main failure forms of hot extrusion molds are excessive plastic deformation in the mold cavity, fatigue damage, thermal wear, and surface oxidation corrosion caused by repeated heating and cooling.

Large die-casting molds are key technologies for achieving integrated die-casting

Abstract: Benefiting from the application of integrated die-casting technology in new energy vehicles, it has brought vitality to the manufacturing of large die-casting molds.

The 2023 Foshan Casting, Forging, and Heat Treatment Exhibition will be held on June 15th

Due to the pandemic and changes in the international trade situation, the manufacturing supply chain has undergone new adjustments and changes. The country has introduced policies such as "new infrastructure" and "dual circulation" to promote the recovery of the manufacturing industry. In the context of declining overseas supply capacity and favorable domestic policies, high-end manufacturing has more upward cycle characteristics, activating the domestic demand market in the manufacturing industry, and promoting consumption upgrading has become one of the important ways for the rise of the Chinese manufacturing market, A batch of new formats and models have emerged, fundamentally subverting traditional work, production, and future business models. Artificial intelligence, Industry 4.0 solutions, and workshop digital twins are becoming increasingly important in the future industrial development.
