The development direction of the automobile industry needs to meet the needs of the construction of ecological civilization. Therefore, energy conservation and emission reduction are the main work content of automobile production. The lightweight of automobile castings has become the main development trend. The engine block of automobile is the main direction to realize the lightweight of castings.
In the process of producing cast iron cylinder block, the products obtained by the traditional production mode have the problems of broken core and floating core. At the same time, the wall thickness of the cylinder block fluctuates seriously, which does not meet the high quality requirements of automobile production. Therefore, it is necessary to use the integral core assembly and vertical casting technology. Since the design and production link requires that the wall thickness of the cylinder block be controlled at 3mm, Therefore, the vertical casting process of core assembly puts forward higher requirements for both core making and core assembly. Technicians need to ensure the automation and intelligence of core production in the process of core making, and apply the automation production technology to all links of core production, including the addition of raw sand, resin and other materials, the process links of sand mixing, core making, core repair, assembly and drying operations, through the application of automation technology, It can effectively improve the quality of core making by sand cores, ensure the assembly quality and size, effectively avoid the quality problems and size problems caused by human factors, and meet the needs of a large number of cylinder core making production. At the same time, the application of automation technology in mass production can reduce the scrap rate and improve the accuracy of core size. In addition, Intelligent technology and automation technology can reduce the labor cost and time cost of production links on the basis of meeting the production requirements of automobile castings, and also have a positive role in improving production efficiency.
