Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a casting type 3D printer frame structure. Background Art

[0002] 3D printing technology, as one of the manufacturing technologies that has rapidly emerged in recent years, has the core concept of deconstructing complex three-dimensional objects into a series of simple two-dimensional layers, and finally reshaping them into three-dimensional entities by stacking these layers layer by layer.

[0003] In sand mold 3D printing technology, after receiving software instructions, the 3D printer nozzle will spray the resin of the corresponding section on the sand surface according to the shape of the model section. The resin reacts chemically with the curing agent in the sand surface, and finally shapes a sand mold of a specific shape through multi-layer superposition and curing.

[0004] With the rapid development of 3D printing technology, the size range of sand mold printing continues to expand, and the requirement for precision has become an indispensable part of the design. In this context, the structural stability of the frame is particularly critical. During the printing process, a stable structure is required to support the object being printed to prevent it from deforming or collapsing during the printing process. However, the stability of the current frame structure when supporting the printed object still needs to be improved. The frame is usually welded from multiple profile parts. This structure is prone to defects such as deformation, and the overall dimensional accuracy of the welding process is low. In addition, the frame is light in weight and has poor seismic resistance. There are many difficulties in the processing process, such as poor consistency, low processing efficiency, high cost, etc., and it is not easy to achieve precise assembly and adjustment. These factors have a certain impact on the printing effect.

[0005] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a casting type 3D printer frame structure. Utility Model Content

[0006] The utility model aims to provide a casting type 3D printer frame structure to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A technical solution for the structure of a casting-type 3D printer frame includes a frame base, a plurality of reinforcing beams are arranged inside the frame base, a front column body and a rear column body are arranged at the front and rear corners of the frame base, a top cover frame is arranged on the top of the front column body and the rear column body, a hanging ring is arranged on the top cover frame, and a mounting plate is arranged on the outside of the top cover frame.

[0009] As a preferred technical solution, the frame base is provided with a base assembly opening, the front column is provided with a front column assembly opening, the rear column is provided with a rear column assembly opening, and the top cover frame is provided with a top cover frame assembly opening.

[0010] As a preferred technical solution, a threaded hole is provided on the top of the top cover frame, and the threaded hole is connected to the lifting ring.

[0011] As a preferred technical solution, a plurality of double-layer shock-absorbing pads are arranged between the frame base and the ground.

[0012] As a preferred technical solution, the front column body, the rear column body and the base assembly opening, the front column body assembly opening and the rear column body assembly opening on the frame base are all assembled and connected by bolts.

[0013] As a preferred technical solution, the front column body, the rear column body, and the front column body assembly opening, the rear column body assembly opening, and the top cover frame assembly opening on the top cover frame are all assembled and connected by bolts.
