The rapid development of digital mold technology in recent years is an effective way to solve many problems faced in the development of automotive molds. The so-called digital mold technology is the application of computer technology or computer aided technology CAX in the mold design and manufacturing process. Global manufacturing competition has entered from the scale of the early 20th century and the reduction of product costs, the improvement of overall efficiency and product quality in the middle and late 20th century, to the delivery, quality, price and service in the late 20th century. Since the 21st century, competition has developed to the ability to innovate.

This situation has led to the focus of manufacturing competition on product development speed and innovation capability. In order to improve innovation capability and efficiency, digital strategy has become the preferred strategy for product innovation of multinational manufacturing enterprises. Digitalization is based on the generation, processing, transmission, use, modification and storage of digital. The digital prototype is the core, with a single data source management as the link, and the analog quantity and the number are replaced by digital in the process of design, manufacture and management. Technology replaces traditional technology and uses digital quantities as the sole basis for design, manufacture and management. Luo Baihui, secretary-general of the International Model Association, believes that the core of the digital manufacturing of the mold manufacturing industry is digital manufacturing technology. Digital manufacturing refers to the rapid collection of virtual reality, computer network, rapid mold forming, database and multimedia support technologies. Resource information, analysis, planning and reorganization of product information, process information and resource information, simulation of product design and function, and prototyping, and rapid production of the entire manufacturing process of products that meet user requirements.

In the next few decades, China will realize the transformation from a large mold industry to a mold industry power, and improve technological innovation capability and product quality. Urgent need. In Luo Baihui's view, speeding up the digital transformation of the mold manufacturing industry and promoting the transformation and upgrading from China's manufacturing to China's intellectual creation, China's economic development mode will undergo fundamental changes.

The main factors affecting the accuracy of mold processing 1. Dimensional accuracy refers to the degree of conformity between the actual size of the part after machining and the tolerance of the part size. Dimensional accuracy is controlled by dimensional tolerances. Dimensional tolerances are the allowable variations in the dimensions of the part during mold machining. In the case of the same basic dimensions, the smaller the dimensional tolerance, the higher the dimensional accuracy. 2. Shape accuracy refers to the degree of conformity between the actual geometry of the surface of the part after the mold is processed and the ideal geometry.

The items for evaluating the shape accuracy include six items such as straightness, flatness, roundness, cylindricity, and line outline. The shape accuracy is controlled by the shape tolerance. The shape tolerances are divided into 12 precision grades except for the roundness and cylindricity. Level 1 is the highest and level 12 is the lowest. 3. Positional accuracy refers to the difference in actual positional accuracy between the surfaces of the parts after processing of Huangjiang mold. The items for assessing positional accuracy include eight items: parallelism, verticality, inclination, concentricity, symmetry, position, round runout, and full runout. Position accuracy Plastic mould is controlled by positional tolerances, and the positional tolerances of each item are also divided into 12 accuracy levels. 4, the relationship between dimensional accuracy,

Shape accuracy and positional accuracy Generally, when designing machine parts and specifying the machining accuracy of parts, it should be noted that the shape error should be controlled within the position tolerance, and the position error should be smaller than the dimensional tolerance. That is, the important surface of precision parts or parts, the shape accuracy requirements should be higher than the position accuracy requirements, and the position accuracy requirements should be higher than the dimensional accuracy requirements.

For extruders below 50MN, generally take 15-50mm, the small tonnage extruder takes the lower limit, and the large tonnage squeezer takes the upper limit. 'Generally, ultrasonic testing and surface quality inspection should be carried out. (2) There is a high enough manufacturing precision, the shape tolerance and dimensional tolerance of the mold meet the requirements of the drawings (generally manufactured according to negative tolerance), and the matching dimensions have good interchangeability. (1) The hardness of the medium W is uniform. According to the extrusion force of the extruder, the length of the extruder receiving table and the cooling table, the size of the extrusion cylinder, the mechanical and mechanical requirements of the product, the deformation resistance of the extruded alloy, and the like; For aluminum alloy bars, A can take 8-40, where the soft balance takes the upper limit, the hard alloy takes the lower limit c(2), and the mold strength c is to increase the service life of the die, the distance between the die hole and the die and the die The distance should be kept at a certain value. 4Py', the surface should be nitrided, phosphatized to treat other surface heat treatment, such as multi-element co-infiltration treatment and chemical heat treatment; (4) have good neutrality, the contact rate should be greater than 80%. After the mold is quenched and tempered, the hardness value HRc is 45-51 (depending on the size of the mold, the larger the size, the lower the hardness required). (6) The transition of the working belt and the transition zone of the cavity of the cavity and the transition of the welding cavity are smooth and evenly transitioned, and no corners are allowed. (4) The metal flow is as uniform as possible.6Mm. (3)

There is a sufficiently low surface roughness, and the roughness of the table should only be 3.6-o.2-1. For large extruders above 80MN, it should be increased to 30-80mm: (3) Good product surface quality: In order to prevent the dirty logistics person on the surface of the ingot from squeezing the product towel, the edge of the die hole and the extruded Plastic cap mold cylinder should be Keep a minimum distance, generally 10% - 30% of the squeezing of the squeezing (the lower limit of the large extruder, the limit of the small extruder), in addition, in order to prevent surface scratches and sprains, reduce 1 : The labor intensity and the amount of waste, the number of plastic mold holes should not be too much. The number of holes in the porous rod die can be selected according to the following principles: (1) Reasonable extrusion coefficient A. What are the main requirements?
