Abstract

The invention discloses a system and method for rapidly forming a water-soluble core and belongs to the technical field of material forming. The system for rapidly forming the water-soluble core comprises a box body, a microdroplet spraying device, a mixing device, a spreading device, a movable heating device, a space heating device, a powder heating device, a liquid distribution bin, a controller, a work cavity, a lifting working platform and a temperature measurement probe. The method for rapidly forming the water-soluble core comprises the steps that firstly, a core CAD geometric solid model is established firstly, liquid dropping process of all dispersed layers is completed by the microdroplet spraying device according to the operation track, extracted by a computer, of a liquid dropping device, and then the water-soluble core is manufactured. The system and method are particularly suitable for rapidly forming and manufacturing the core with a water-soluble inorganic salt solution as an adhesion agent. By the adoption of the system and method, the water-soluble cores which are in any complicated shapes can be directly manufactured; due to the fact that a core mould does not need to be manufactured according to the method, manufacturing cost is reduced, and a product development period is shortened.

Description

Technical field: [0001] The invention belongs to the technical field of material forming, and specifically relates to a rapid prototyping system and a forming method for a water-soluble core. The method is particularly suitable for rapid prototyping manufacturing of a core using a soluble inorganic salt solution as a binder. Background technique: [0002] There are a large number of aluminum alloy castings with complex cavities and curved channels in the automotive, engineering machinery and aerospace fields. These complex aluminum alloy castings can be produced with built-in metal cores, resin sand cores and water-soluble cores. Due to the complex core-making process of metal cores, and the use of chemical core removal, it is easy to cause environmental pollution, which promotes the use of organic resin sand cores with excellent comprehensive performance in the production of such castings. In recent years, with the development of process technology, the molding temperature of a...
