Dewaxing device and process

Abstract

The invention relates to a novel process and device for dewaxing in precision casting production, in particular to a dewaxing device and process. The technical scheme provided by the invention is that: the dewaxing device comprises a dewaxing box body, wherein fire resistant materials are paved on a bottom surface of the interior of the dewaxing box body; resistance wires connected with a power source are distributed on the fire resistant materials; a container support plate and a wax mould support plate are sequentially arranged from bottom to top in the dewaxing box body above the resistance wires; a heat-conducting container is placed on the container support plate; and small holes are arranged in the container support plate and the wax mould support plate. The dewaxing device and process provided by the invention have the advantages of adopting a technological method of heating right amount of water by utilizing ordinary resistance wires; and by means of the method, the problems that the water consumption of a boiler is large, the temperature rise is slow and the energy utilization is low are solved.

Description

technical field [0001] The invention relates to a process and equipment for dewaxing fine casting production, in particular to a dewaxing equipment and process. Background technique [0002] Lost wax casting essentially refers to the model manufacturing method, that is, the lost wax method is used to manufacture component models, which can achieve precision, accuracy, meticulousness, high flexibility, and strong adaptability. It is especially suitable for components with complex structures. The method is simple and convenient. , does not require modern processing equipment such as CNC machine tools. With the development of society, precision casting has been widely used in all industrial sectors including aviation and weapons, especially in electronics, petroleum, chemical industry, medical machinery, pumps and valve components. At present, most of the dewaxing equipment in our country adopts high pressure 0.8Mpa steam is used for dewaxing, and the steam source is an oil-fi...

Problems solved by technology

With the development of society, precision casting has been widely used in all industrial sectors including aviation and weapons, especially in electronics, petroleum, chemical industry, medical machinery, pumps and valve components. At present, most of the dewaxing equipment in our country adopts high pressure 0.8Mpa steam is used for dewaxing, and the steam source is an oil-fired boiler or an electric boiler. The investment and maintenance costs of the boiler are high, the energy consumption is large, and the heating time is long (1~1.5 hours), which is increasingly unsuitable for the development of energy conservation and environmental protection.
