The shell casting process of lost foam casting has cleaned the foam thoroughly and thoroughly through the roasting process before pouring liquid metal. Therefore, it thoroughly eliminated the unfriendly influence and trouble caused by the foam mold in the liquid metal forming process. Very careful, always on tenterhooks, the...
According to the analysis of the casting structure and key casting technology difficulties of the intake cylinder, this paper mainly focuses on the theoretical research, design and calculation of the core casting technology scheme and process of the intake cylinder, and determines the final optimization process technology scheme. In...
As one of the key parts of the engine, the cast iron parts of the engine block have high quality requirements, and the structure of the cylinder block is more complex than that of the general castings, so it is difficult to produce, and a large number of core...
The casting properties of ductile iron have the following characteristics ① The content of sulfide and oxide in molten iron is high. In addition, oxides are easily produced if exposed to air and gas. ② Graphitization expansion is easy to cause casting swell, and the dimensional accuracy is easily...
In the field of digital casting abroad, it is more reflected in the whole process automation of casting process. Kurtz company of Germany has realized the digitalization, automation and remote monitoring of the whole production process, and has realized the intelligent control of casting quality and the information management...
It has been proved by a lot of practice that the process design of gating system is the key problem that restricts the casting quality and performance of cylinder block iron castings under sand mold conditions, which has attracted extensive attention of manufacturers. Cylinder block castings have many machining...
The State Key Laboratory of advanced forming technology and equipment of China Academy of Mechanical Sciences has systematically studied the technology and equipment of sand mold digital dieless casting, and developed a series of digital dieless casting precision forming equipment with independent intellectual property rights (as shown in the...
Material, mold, core making and inspection are the four basic aspects of engine block casting, which run through the whole process of engine block casting. Gray cast iron is widely used in engine block castings in China, especially HT250. In order to meet the requirements of good machinability of...
Molding manufacturing technology can be used not only in functional testing, but also in product conceptual design, and also in mold design and manufacturing. It is also widely used in the fields of medical treatment, household appliances, automobile and handicraft production. Rapid tooling manufacturing The solid model generated by...
The pillar industry of China’s economic development is the modern machinery manufacturing industry. In order to promote the sound and rapid development of China’s economy, we must integrate with the international advanced manufacturing technology. In the 21st century, China’s network technology, computer technology, sensing and other high-tech rapid development,...
