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

Abstract

The invention relates to the field of alloy investment casting, in particular to a high-temperature alloy complex thin-walled workpiece casting system which is characterized in that two cross gates Care symmetrically arranged on the left and right sides of the top of a sprue, two cross gates B and two cross gates A are symmetrically arranged on the front and back sides of the sprue successively,the cross gates A are located below the cross gates B, a pair of cross gates D is symmetrically arranged on the front and back side of the cross gates C, an anti-deformation rod M is arranged betweentwo front pin hole seats of a casting wax mould, and an anti-deformation rod N is arranged in a rotating pin hole seat of the device in the casting wax mould. When the casting wax mould is pressed, via the mould, the anti-deformation rod M, the anti-deformation rod N and the casting wax mould are formed integrally. A sprue cup communicates with the sprue of a basic casting unit directly, and two exhaust passages are arranged symmetrically and communicates with the cross gates C and the sprue cup. The risk of defects such as deformation, looseness, cracks and the like can be reduced effectively, and the casting percent of pass of casting products is improved.

Description

technical field [0001] The invention relates to the field of alloy investment casting, in particular to a pouring system for complex thin-wall 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 structure stability, so it can well meet the special needs of high temperature bearing 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, 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. The casting involved in the present invention has many reinforcing ribs, and the wa...
