Abstract

The invention discloses a 3D printing clay molding sand mold device and method. The device comprises a computer and control system, a forming system, a powder spreading system and a clay molding sandmold; the computer and control system is connected with the forming system and the powder spreading system, the forming system is arranged on the upper part of the powder spreading system, and the clay molding sand mold is arranged in the middle part of the powder spreading system, a solution spraying system is arranged in the forming system, the solution spraying system is connected with a solution spraying system moving device, the solution spraying system, the solution spraying system moving device and a drying system are connected with a forming system moving device; and powder in the powder spreading system is located above a forming area bottom plate and a powder supplementing area bottom plate, a forming area bottom plate lifting device is connected with the forming area bottom plate, a powder supplementing area bottom plate lifting device is connected with the powder supplementing area bottom plate, and the powder spreading device is arranged between the solution spraying system and the drying system and is connected with the forming system moving device. According to the method adopted by a mold, the characteristics of low air permeability and low gas evolution can be kept, and the possibility of air holes in a casting is reduced.

Description

technical field [0001] The invention belongs to the technical field of casting, and relates to a device and method for 3D printing clay sand casting molds. Background technique [0002] At present, in the existing technology, the common method of rapid manufacturing of casting molds based on 3D printing (layered manufacturing technology) is basically by spraying resin binder and curing agent, and then bonding the molding sand together to form resin sand casting. type. [0003] The specific method of layered manufacturing of this resin sand mold is to decompose the object to be processed into multiple parallel thin layers, and to manufacture and superimpose these thin layers layer by layer to complete the manufacturing process of the entire mold. Commonly used manufacturing methods mainly include the following two types: one is to selectively sinter resin-coated sand with laser. The basic method used is: spread a layer of resin-coated sand on the workbench, heat it to a tem...
