Abstract

The invention relates to a gravity casting-liquid forging combined casting device and process. The casting device has three forms, the first form comprises a base, an upper die, a side die set, a fixed die, a moving die, a pouring cup, a plugging slide block, a plugging sliding groove, a pressurizing oil cylinder, a rack and a handle; the second form comprises a base, an upper die, a side die set,a movable die, a pouring cup, a plugging sliding block, a plugging sliding groove, a pressurizing oil cylinder, a positioning pin, a handle and a rack; and the third form comprises a base, an upper die set, a side die set, a plurality of movable dies, a pouring cup, a plugging sliding block, a plugging sliding groove, a plurality of pressurizing oil cylinders, a rack and a handle. According to the casting device and process, gravity casting and liquid forging are organically combined together, the pressure on liquid metal is increased through gravity casting equipment, so that the liquid metal is solidified under the pressure, the inherent quality of castings is remarkably improved, shrinkage porosity and shrinkage cavities are reduced, and the mechanical property is improved; and the device is simple in structure, low in cost and high in casting molding speed, and the production efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of casting technology, and in particular relates to a casting device and technology combining gravity casting and liquid die forging. Background technique [0002] Pressure coagulation has many advantages. The metal liquid solidifies under pressure, and as the pressure increases, the feeding capacity of the interdendritic alloy liquid increases, which reduces the shrinkage cavity and porosity of the solidified sample, and increases the density, thereby effectively reducing the porosity of the casting. When the applied pressure increases, the subcooling degree of the metal liquid can also be increased, so that the number of spontaneous nucleation nuclei increases, thereby refining the grains. These advantages have improved the quality of castings and improved their mechanical properties. [0003] Gravity casting refers to the process in which molten metal is poured into the mold under the action of the grav...
