Description

Technical Field

[0001] This utility model belongs to the field of sand mold 3D printing technology, specifically a non-metallic base for sand mold 3D printing equipment. Background Technology

[0002] Traditional manufacturing methods for machine tool bases in the equipment manufacturing industry involve using castings, metal welding, aluminum alloy profiles, and precision machining. When using giant sand mold 3D printers, it is usually necessary to increase the height of the 3D printer body to meet the printing space requirements. Due to the large length and width of the body, in order to improve the support stability of the body, casting, steel structure, or steel structure plus aluminum alloy structure are used to make the base. However, the base made by casting is heavy, which is not conducive to production, installation, and transportation, and the cost is high.

[0003] Chinese patent application CN201621171238.1 discloses a motion platform for a 3D printer, comprising: a marble frame, motion guide rails on both sides of the marble frame, two motor mounting bases at one end of the marble frame, a motor and a coupling on each of the two motor mounting bases, the two couplings being connected to one end of a ball screw, the other ends of the two ball screws being fixed to the marble frame by bearing mounting bases, the two ball screws being connected to a printing motion seat via a synchronous belt, and the printing motion seat being slidably connected to the motion guide rails. This structure, by using marble as the frame material for the printing platform and placing the motion guide rails on the marble, makes the guide rails smoother, and the non-metallic motion seat operates more stably during operation, ensuring the motion accuracy between the X, Y, and Z axes and the flatness between the three axes, thereby significantly improving the accuracy of 3D printing. However, while this solution utilizes non-metallic materials to increase the running accuracy of the motion guide rails, it does not describe the machine base connected to the non-metallic material and does not reduce the production cost of the 3D printer.

[0004] Furthermore, during actual production and use, the stress inherent in the metal material of the base and the influence of external temperature and humidity can cause varying degrees of bending deformation on the surface of the working components. In addition, the base is large in size and has high production costs, and is difficult to transport.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a non-metallic base for sand mold 3D printing equipment. Utility Model Content

[0006] The purpose of this invention is to address the above problems by providing a non-metallic base for sand mold 3D printing equipment, which has the advantages of improving printing accuracy and reducing production costs.

[0007] To achieve the above object, the utility model provides the following technical scheme: A nonmetallic base for sand mould 3D printing equipment, including lower base, the nonmetallic base whole is composed of nonmetallic material, one end of lower base is provided with bearing part, the bearing part is connected with working assembly setting work assembly away from one end of lower base;

[0008] The bearing part is composed of anti-deformation hard nonmetallic material, and the bearing part is used for supporting and fixing the working assembly of the sand mould 3D printing equipment.

[0009] The nonmetallic base for sand mould 3D printing equipment further includes a connecting assembly arranged between the bearing part and the lower base for fixing the bearing part.

[0010] Preferably, the anti-deformation hard nonmetallic material used in the bearing part includes marble.

[0011] Preferably, the anti-deformation hard nonmetallic material used in the bearing part includes granite.

[0012] Preferably, the anti-deformation hard nonmetallic material used in the bearing part includes a resin mixture.

[0013] Preferably, the working assembly includes a sliding rail fixedly connected to the bearing part, and a connecting beam slidingly arranged on the sliding rail.

[0014] Preferably, a locking part for fixing the bearing part is arranged on the sliding rail.

[0015] Preferably, the nonmetallic material used in the lower base includes reinforced concrete material.

[0016] Preferably, the nonmetallic material used in the lower base includes a resin mixture.

[0017] Compared with the prior art, the utility model has the beneficial effects as follows:

[0018] The utility model replaces the metal material of the lower base with reinforced concrete structure, reduces the transportation and production cost of the lower base, and replaces the bearing part for supporting the sliding rail with marble, granite, quartz stone, resin plate or other hard and anti-deformation nonmetallic material. The use of nonmetallic material instead of metal material improves the rigidity and shock resistance of the lower base and the bearing part to the working assembly, effectively reduces the possibility of deformation of the lower base under stress during use, improves the printing precision of the sand mould 3D printing equipment, reduces the production cost, and improves the printing speed of the sand mould 3D printing equipment.
