Description

Technical Field

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

[0002] When using a giant sand mold 3D printer, it is usually necessary to increase the height of the printer base to meet the printing space required. Due to the large length and width of the base, heavy castings, steel components, or steel structures with aluminum alloy components are used to make the base in order to improve the support stability. However, the base made in this way is heavy, which is not conducive to production, installation, and transportation, and the cost is also high.

[0003] Chinese patent application CN201920573570.8 discloses a sand mold 3D printer, which includes a printing base, crossbeams, a ground rail, a sand supply system, a sand-laying beam, a printing beam, and a work box. The crossbeams consist of two parallel beams mounted on the printing base, with the ground rail located below them. The sand supply system is fixed to the crossbeams, and the sand-laying beam and printing beam are mounted on the crossbeams at both ends and slidably connected to them. The work box is mounted on and slidably connected to the ground rail. While this design effectively reduces the size of the equipment and ensures continuous sand supply through a sand supply system with two sand tanks, and improves operational stability and reduces noise by using linear motors to drive the printing beam and sand-laying beam, and enables continuous printing with two work boxes to increase printing efficiency, it does not address the problem of deformation of the base structure affecting printing accuracy during use.

[0004] Furthermore, in actual production and use, the stress inherent in the metal material itself and the influence of external temperature and humidity can cause varying degrees of bending deformation on the surface of the base. This can lead to fluctuations in the printing components during operation, affecting the printing accuracy of the 3D printer. Consequently, the level of the work platform needs to be constantly calibrated, which in turn affects printing efficiency.

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

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

[0007] To achieve the above objectives, this utility model provides the following technical solution: a base for improving the accuracy of sand mold 3D printing equipment, including a lower base, a leveling component is provided on the lower base, a support part is connected to the end of the leveling component away from the lower base, a working component is connected to the end of the support part away from the leveling component, and the lower base is made of metal material;

[0008] The support is made of a deformation-resistant hard non-metallic material and is used to support and fix the working components of the sand mold 3D printing equipment.

[0009] Preferably, the metal material used for the lower base includes castings.

[0014] Preferably, the working component includes a slide rail, which is fixedly connected to the support, and a bearing rod is slidably mounted on the slide rail.

[0015] Preferably, the leveling assembly includes machine tool leveling feet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention improves the support strength of the working components by setting the lower base to a metal material and replacing the support part used to support the slide rail with a deformation-resistant hard non-metallic material. At the same time, it significantly reduces the weight of the lower base, lowers its production cost, improves the accuracy of sand mold 3D printing equipment, reduces production costs, reduces the number of adjustments after use, and improves the printing efficiency of sand mold 3D printing equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Since the lower base of existing sand mold 3D printing equipment is mostly made of steel structure and aluminum alloy profile, during use, the stress of the material itself will cause varying degrees of bending deformation, which will affect the movement trajectory of the base during the printing process, causing the printing accuracy of the sand mold 3D printing equipment to decrease and affecting the printing efficiency.

[0024] like Figure 1 - Figure 2 As shown, this utility model is a base for improving the accuracy of sand mold 3D printing equipment, including a lower base 1. The lower base 1 can be composed of a lightweight metal frame, reducing the stress concentration area on the support part 3. At the same time, the lightweight metal frame has good strength and hardness, which can stably support the support part 3 during use. When the lower base 1 is a lightweight metal frame, the deformation-resistant hard non-metallic material of the support part 3 can also be connected to the steel component. When the steel component deforms, due to the material properties of the support part 3, it will not affect the horizontal state of the support part 3.

[0025] It should be noted that when the lower base 1 adopts a lightweight metal frame, the lower base 1 can be made of castings, steel components, or aluminum alloy profiles, which can effectively reduce the manufacturing cost of the lower base 1 and improve the printing accuracy of the printing equipment.

[0026] The casting of the lower base 1 is preferably cast iron. Cast iron has a low production cost, high strength and hardness, is suitable for bearing high loads, and has good shock absorption performance during use, which can reduce the vibration impact of the working component 4 during operation and improve the printing accuracy of the sand mold 3D printing equipment.

[0027] A leveling component 2 is provided on the lower base 1. A support part 3 is connected to the end of the leveling component 2 away from the lower base 1. The leveling component 2 can level and calibrate the support part 3. A working component 4 for use in sand mold 3D printing device is connected to the end of the support part 3 away from the leveling component 2.

[0028] Furthermore, the support part 3 is mainly composed of deformation-resistant hard non-metallic materials, including stone, artificial synthetic stone and resin materials, including but not limited to marble, granite, quartz stone, resin board or other hard and deformation-resistant hard non-metallic materials. If necessary, the support part 3 can be directly connected and fixed to the lower base 1, and then the plane of the support part 3 can be finely machined to meet the connection requirements of the working component 4.

[0029] It should be noted that the deformation-resistant rigid non-metallic material of the support part 3 can also be formed by casting reinforced concrete. When installing the lower base 1, the connection between the lower base 1 and the support part 3 is reinforced by the leveling component 2, and then the support part 3 is cast and shaped using reinforced concrete. After the plane of the support part 3 is cured, the plane of the support part 3 is precision machined to ensure that the plane of the support part 3 can meet the usage requirements of the working component 4.

[0030] The leveling component 2 consists of machine tool adjustment feet. The leveling component 2 is used to detect and adjust the levelness of the surface of the support part 3 after installation, so as to ensure that the surface of the support part 3 is in a level state and that the error will not interfere with the printing work of the sand mold 3D printing equipment.

[0031] like Figure 3 As shown, the working component 4 further includes two parallel slide rails 401, and both slide rails 401 are fixedly connected to the support part 3. A bearing rod 402 is slidably provided on the slide rail 401. The bearing rod 402 is used to connect the printing component of the sand mold 3D printer. When the bearing rod 402 slides on the slide rail 401, it drives the printing component of the sand mold 3D printer to move, ensuring that the sand mold 3D printer can print normally. During installation, the slide rail 401 can be installed on the surface of the reference surface of the support part 3, or the support part 3 can be embedded in the support part 3.

[0032] During the installation of the equipment in this utility model, the lower base 1 is formed by casting. After it solidifies, a leveling component 2 is installed on the lower base 1. Then, the support part 3 is connected to the leveling component 2, and the levelness of the support part 3 is detected. This improves the stability of the sand mold 3D printing equipment during operation. At the same time, since the support part 3 is mainly composed of deformation-resistant hard non-metallic materials, including stone, artificial synthetic stone, and resin materials, including but not limited to marble, granite, quartz stone, resin board, or other hard and deformation-resistant non-metallic materials, it will not bend or deform due to the working intensity of the working component 4 during use. This reduces the possibility of errors in the sand mold 3D printing equipment during the printing process, increases the printing speed, and thus improves the printing accuracy and efficiency.

[0033] In this invention, the material of the lower base 1 is set to metal, and the support part 3 used to support the slide rail 401 is replaced with a deformation-resistant hard non-metallic material. This improves the support strength of the lower base 1 and the support part 3 for the working component 4, while effectively reducing the possibility of deformation of the lower base 1 under stress during use. This improves the printing accuracy of the sand mold 3D printing device during the printing process, reduces production costs, reduces the number of adjustments after use, and improves the printing efficiency of the sand mold 3D printing device.
