What are the key technical requirements of precision injection molds? The key technical requirements of precision injection molds include the following aspects: (1) Mold material selection: the physical, chemical and mechanical properties of mold materials have an important impact on the accuracy and service life of the mold. For precision injection molds, it is necessary to choose high-precision and high-hardness materials, such as cemented carbide, stainless steel, high-speed steel, etc. (2) Mold structure design: The structural design of precision injection mold needs to take into account the specifications of the injection machine, the injection process, the shape and accuracy of the product and other factors, and also needs to ensure the convenience of mold manufacturing and maintenance. Structural design includes parting surface design, gate location selection, exhaust groove design, etc., which needs accurate calculation and design. (3) Cavity processing technology: the cavity of precision injection mold is the key part of the mold, and its processing accuracy and surface quality have a direct impact on the accuracy and service life of the mold. The machining of the cavity requires the use of CNC machine tools, EDM, laser cutting and other high-precision processing equipment and advanced processing technology to ensure the accuracy and stability of the cavity. (4) Gate design technology: The gate is a channel connecting the injection machine nozzle and the mold cavity, and its design has an important impact on the accuracy and production efficiency of injection molding. Precision injection mold needs to design a reasonable gate location and gate size to ensure that the plastic melt can smoothly flow into the cavity, while avoiding the impact of gate marks on the appearance of the product. (5) Cooling system design technology: The cooling system of precision injection mold is very important to improve production efficiency and ensure product quality. The design of the cooling system needs to fully consider the structure of the mold, injection speed and product shape and other factors to ensure that the mold can be cooled and shaped quickly during the injection process. (6) Maintenance and maintenance technology: precision injection molds need regular maintenance and maintenance, including cleaning, lubrication, inspection, etc. Proper maintenance and maintenance can extend the service life of the mold and improve the stability and reliability of the mold. In summary, the key technical requirements of precision injection mold include reasonable mold material selection, scientific mold structure design, high-precision cavity processing technology, reasonable gate design technology, efficient cooling system design technology and correct maintenance and maintenance technology. The rational application of these technologies can produce high-precision, high-quality plastic products.
