Forming box mechanism for 3DP printing technology

Abstract

The invention discloses a forming box mechanism for a 3DP printing technology. The forming box mechanism for the 3DP printing technology comprises a forming rack, a forming box body, a forming platform, a jacking assembly, a sealing sponge and a sealing pressing plate, the forming box body is slidably inserted into a workbench of the forming rack, the forming platform is arranged in the forming box body, the forming platform is driven by the jacking assembly to move up and down in the forming box body, a sealing groove is formed in the periphery of the upper plane of the forming platform, the sealing sponge is arranged on the sealing groove, the sealing pressing plate for packaging the sealing sponge is arranged on the forming platform, and the sealing sponge is tightly attached to the inner wall of the forming box body. By means of the mode, the forming box mechanism for the 3DP printing technology is compact in structure and ingenious in design, supports products in the layer-by-layer printing process, cancels small cylinder supports on original products, achieves efficient utilization of printing materials, avoids waste of the printing materials, and guarantees printing precision and printing stability.

Description

technical field [0001] The invention relates to the field of sand mold 3DP printing technology, in particular to a forming box mechanism for 3DP printing technology. Background technique [0002] The method often used in 3DP printing technology is to add some supporting structures around the parts on a flat plate to prevent the deformation and fracture of the parts, such as figure 1 As shown, a part is supported by a number of small cylinders with the bottom facing up, so as to ensure the integrity of the size and structure of the part. This method is easily affected by environmental factors, and too many parts are supported, which wastes the printing material and will cause problems in the later stage. It takes a lot of labor and energy to clean the support. The accuracy of this process is relatively poor, and it is not suitable for industrial-grade production printing. From the perspective of printing safety, the printing machine is damaged because there are no reasonable ...

[0002] The method often used in 3DP printing technology is to add some supporting structures around the parts on a flat plate to prevent the deformation and fracture of the parts, such as figure 1 As shown, a part is supported by a number of small cylinders with the bottom facing up, so as to ensure the integrity of the size and structure of the part. This method is easily affected by environmental factors, and too many parts are supported, which wastes the printing material and will cause problems in the later stage. It takes a lot of labor and energy to clean the support. The accuracy of this process is relatively poor, and it is not suitable for industrial-grade production printing. From the perspective of printing safety, the printing machine is damaged because there are no reasonable protection measures for printing. In addition, There is a printing method called 3DPP printing, which is the three-dimensional inkjet printing method. The printing principle is: the 3DP printing machine first lays a layer of printing material on the platform, and then the printing head sprays the material to make the material solidify.
