Embodiment Construction

[0024] The present invention proposes an integrated molding device for sand laying and printing, such as figure 1 As shown, the device includes: a sand storage tank 1, storing enough molding sand before printing sand molds, the sand storage tank 1 is connected with a vacuum feeding device 2, and the vacuum feeding device 2 sucks the molding sand into the sand mixing device 3, and the sand mixing device 3 is also connected with the curing agent storage tank 4, and the curing agent storage tank 4 sends the curing agent into the sand mixing device 3 to be stirred together with the molding sand, and the molding sand and the curing agent are uniformly mixed in the process. After the printing starts, the sand mixing device 3 sends the molding sand not mixed with curing agent into the sand paving device (P1) 8 of the double sand paving and printing integrated device. The integrated device 12 will move horizontally from left to right to evenly lay a layer of bottom sand, and then move...

Abstract

The invention belongs to the field of rapid forming equipment and discloses a 3D printing forming device integrating sanding and printing. According to the D printing forming device integrating sanding and printing, a double sanding and printing integration system is designed, and a sanding device and a printing device are effectively combined, thus the sanding process and the printing process can be simultaneously carried out; and an idle stroke in the sanding and printing process in a single sanding-printing system of traditional 3D printing is removed, thus the manufacturing time of a single-layer sand mould is greatly shortened, and the manufacturing efficiency of the sand mould is improved. By manufacturing the sand mould by adopting a method, the manufacturing mode of 3D printing the sand mould in single and small batch is facilitated, and the 3D printing forming device integrating sanding and printing has very strong popularization and use values.

Description

technical field [0001] The invention belongs to the field of rapid prototyping equipment, and in particular relates to a 3D printing forming device integrating sand laying and printing. Background technique [0002] Sand mold 3D printing is a rapid prototyping technology mainly based on droplet jet forming. At present, sand mold 3D printing equipment is mostly rapid prototyping equipment based on powder bed. The forming process involves the storage, supply, laying, recycling of molding sand, and on-demand injection of resin binder. After the molding sand pre-mixed with the curing agent, the sand and gravel are bonded and solidified into the required sand mold. [0003] In the existing sand mold 3D printing equipment, the sand laying device and the printing device operate independently, and they each have a set of motion systems. During the sand mold manufacturing process, the sand laying device first starts to move and lay the molding sand. After the sand laying is complete...
