Description

A casting device combining gravity casting and liquid die forging

technical field

The utility model belongs to the technical field of casting technology, in particular to a casting device combining gravity casting and liquid die forging.

Background technique

Pressure coagulation has many advantages. The metal liquid solidifies under pressure. With the increase of pressure, the feeding ability of the interdendritic alloy liquid increases, which reduces the shrinkage porosity and shrinkage porosity of the solidified sample, and increases the density, which can effectively reduce the shrinkage porosity of the casting. When the external pressure increases, the subcooling degree of the metal liquid can also be increased, so that the number of spontaneous nucleation cores increases, thereby refining the grains. All these advantages lead to improved casting quality and improved mechanical properties.

Gravity casting refers to a process in which molten metal is injected into a mold under the action of the earth's gravity, also known as gravity casting. The existing gravity casting machine is actually a mold opening and closing machine, which has simple process, simple equipment and low cost.

Liquid die forging, also known as squeeze casting, is a specific application that utilizes the characteristics of pressure solidification. It pours a certain amount of metal liquid directly into the open metal mold, and acts on the liquid metal with a certain pressure through the punch to fill, form and crystallize it. During the solidification process, it is subjected to the pressure of the punch, resulting in a certain amount of plastic deformation. Because the liquid metal crystallizes and solidifies directly under pressure, the casting will not produce casting defects such as pores, shrinkage cavities and shrinkage porosity, and the structure is dense and the mechanical properties are higher than that of low-pressure castings. This casting process has been used in many applications. However, this process is relatively complex, the equipment is huge and complicated, which makes the production cost of castings high, and its application is limited.
