Problems solved by technology

However, due to the characteristics of the alloy, such as large mushy area, high liquid viscosity, and serious loosening tendency, it is especially used in the production of thin-walled parts. During the casting process, thin-walled parts are difficult to form (under-cast), easy to loosen and crack, and the casting process is difficult. great

Embodiment 1

[0031] like figure 2 As shown, a casting system for complex thin-walled parts of superalloy, the casting system is composed of a two-piece type:

[0032] The pouring system is provided with a basic pouring unit, a pouring cup 8 and an exhaust channel 9. The basic pouring unit consists of a sprue 1, a runner A2, a runner B5, a runner C6, a runner D7, It is composed of anti-deformation rod M4 and anti-deformation rod N10. The specific structure of the casting system is as follows:

[0033] The basic pouring unit structure is that two runners C6 are symmetrically arranged on the left and right sides of the bottom of the sprue 1, and two runners B5 and two runners A2 are arranged symmetrically on the front and rear sides of the sprue 1 in turn, and The runner A2 is located below the runner B5, a pair of runners D7 are symmetrically arranged at the outer ends of the front and rear sides of the runner C6, and the anti-deformation rod M4 is arranged between the two front pin holes ...

Embodiment 2

[0044] like image 3 As shown in the figure, a casting system for complex thin-walled parts of superalloy, the casting method of the casting system is a set of four parts:

[0045] The pouring system is provided with two basic pouring units, a pouring cup 8 and an exhaust channel 9. The basic pouring unit consists of a sprue 1, a runner A2, a runner B5, a runner C6, a runner D7. It is composed of anti-deformation rod M4 and anti-deformation rod N10. The specific structure of the pouring system is as follows:

[0046] The basic pouring unit structure is that two runners C6 are symmetrically arranged on the left and right sides of the bottom of the sprue 1, and two runners B5 and two runners A2 are arranged symmetrically on the front and rear sides of the sprue 1 in turn, and The runner A2 is located below the runner B5, a pair of runners D7 are symmetrically arranged at the outer ends of the front and rear sides of the runner C6, and the anti-deformation rod M4 is arranged bet...

Abstract

The invention relates to the field of alloy investment casting, in particular to a casting system for complex thin-walled parts of high-temperature alloys. Two runners B and two runners A are set, and the runners A are located below the runners B, a pair of runners D are symmetrically arranged at the outer ends of the front and rear sides of the runners C, and the anti-deformation rods M are set Between the two front pin hole seats of the casting wax mold, the anti-deformation rod N is arranged in the rotating pin hole seat of the device in the casting wax mold. It is integrally formed with the casting wax mold; the sprue cup is directly connected with the sprue of the basic pouring unit, and two exhaust ducts are symmetrically arranged, both of which are connected to the sprue C and the sprue cup. The risk of defects such as porosity and cracks is improved, and the casting qualification rate of casting products is improved.

Description

technical field [0001] The invention relates to the field of alloy investment casting, in particular to a casting system for complex thin-walled parts of high-temperature alloys. Background technique [0002] JG4246A alloy has a series of advantages such as light specific gravity, high high temperature strength, excellent oxidation resistance and high temperature microstructure stability, which well meets the special needs of high temperature bearing capacity and ablation resistance of a certain type of thin-walled parts of the third and fourth generation machines. However, due to the characteristics of the alloy's large mushy area, high liquid viscosity, and serious loosening tendency, especially in the production of thin-walled parts, there are difficulties in forming thin-walled parts (under-casting), easy loosening and cracking during the casting process, and the casting process is difficult. great. The present invention involves many reinforcing ribs of the casting, an...
