Problems solved by technology

[0002] At present, when processing flange workpieces by casting, the sand boxes used are often traditional sand box structures. Although they can meet the needs of use to a certain extent, on the one hand, the flexibility of casting processing is poor, and the processing efficiency cannot be flexibly adjusted according to the needs of use. and output; on the other hand, in the process of processing, it is impossible to adjust the condensation molding efficiency, and it is also impossible to monitor and adjust the temperature change in the condensation process, which leads to low molding efficiency and is also very easy to die due to uneven cooling temperature distribution. Causes internal stress concentration of the workpiece, and in severe cases, the structural strength of the flange workpiece is poor, internal cracks, etc. seriously affect the quality of the flange due to stress concentration.
[0003] At the same time, the current sand box lacks the ability to effectively modulate the metal crystal phase structure during the cooling and forming process, which further affects the structure of the casting flange workpiece

Abstract

The invention discloses an efficient flange mold structure for flange rapid forming. The efficient flange mold structure for flange rapid forming comprises a bearing base, a sealing end cover, a forming box body, molding sand, forming sand cores, a bearing keel, a heat exchange pipe, an electromagnet, a temperature sensor and a driving circuit, the bearing base and the sealing end cover are connected through the forming box body, the bearing keel is embedded in the forming box body, the forming sand cores are embedded in the forming box body through the bearing keel, the molding sand is located in the forming box body and coats the forming sand cores and the bearing keel, and a runner and an exhaust passage are arranged at each of the positions, corresponding to the forming sand cores, ofthe molding sand. The casting method based on the efficient flange mold structure for flange rapid forming comprises two steps of equipment assembly and casting operation. According to the efficient flange mold structure for flange rapid forming and the casting method, on one hand, the requirement for casting machining of one or more flange workpieces can be flexibly met according to use requirements; and on the other hand, the defects of poor metal material structural strength and sand holes, cracks and the like of a flange structure caused by stress concentration inside the flange can be effectively eliminated.
