Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with specific embodiments, but the embodiments of the present invention are not limited thereto. In the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other:

[0023] as attached figure 1 Among them, the combination of the casting formwork 1 and the pouring tool 2 needs to be connected through the tile tool in the middle. During the pouring process, the middle tile tool will produce impurities due to high temperature and affect the quality of the finished product.

[0024] A method for connecting mold shells and tooling in spin casting, characterized in that it includes mold shell shaping, assembly steps, adhesive preparation, seam patching, and mold group heating steps;

[0025] Among them, mold shell shaping: clean the mold shell to be poured and remove the flash;

[0026] Assembly: dock the sprue cup of the formw...

Abstract

The invention relates to a mold shell and tool connecting method in spin force casting. The method comprises the steps of mold shell shaping, assembly step, adhesive mixing, joint patching and moduleheating. Bauxite is used as materials in adhesives, so that a cast mold shell and a casting tool are stably combined; and meanwhile, a steel tile tool is prevented, so that the defect problems of casting looseness and slag inclusion in the spin force casting process are solved.

Description

technical field [0001] The patent of the invention belongs to the technical field of investment casting, and in particular relates to a method for connecting mold shells and tooling in spin casting. Background technique [0002] Investment precision casting is widely used in aviation, aerospace, weapons, electronics, ships and other industries. With the continuous development of casting technology, the requirements for investment precision casting are getting higher and higher. In recent years, more and more complex thin-walled hollow structure castings have become more and more difficult to cast, especially thin-walled and complex castings have extremely high metallurgical requirements, and the traditional gravity casting process has a low yield rate. The branch factory uses spin casting to solve the problem. Casting loose, slag inclusion and other defects. At present, steel materials are used to connect formwork and tooling, which has high cost and poor metallurgical qual...
