Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a sand mold moving mechanism of a laser 3D printer. Background Art

[0002] 3D printing is a rapid prototyping method. With the advancement of science and technology, the application of 3D printing technology in the field of casting sand mold printing has been gradually promoted.

[0003] The production of traditional casting molds requires a lot of time and manpower, and the manufacturing process is complicated and prone to errors. When producing sand molds for large and complex castings, it is necessary to obtain them by splicing and combining multiple sand molds. If the dimensions and spatial positions of each sand mold are slightly deviated, the cast product may be scrapped, resulting in an increase in the defective rate and low production efficiency. With the help of 3D printing technology, the designer's ideas can be directly converted into a physical model, which greatly improves production efficiency and manufacturing accuracy, and realizes the seamless connection between 3D printing technology and the casting industry. The principle of the sand mold laser 3D printer is to solidify the sand mold through laser sintering layer by layer. The sand mold after printing needs to be dried. The purpose of drying is to reduce the moisture content of the sand mold, reduce the gas emission during the pouring process, and improve the strength and air permeability, thereby ensuring the quality of the casting. However, the newly formed sand molds are relatively fragile, and some sand molds are large in size, which are easily damaged by collision during the process of transferring them to the drying room.

[0004] The existing announcement number is CN205763647U, which is a sand mold moving mechanism of a laser 3D printer, including a connecting track, one end of which is connected to the laser printer, and the other end is connected to the drying box. A bracket is provided below the connecting track, and a driving device is provided in the bracket. The driving device includes a motor, and a first sprocket is fixed on the output shaft of the motor. The first sprocket is connected to the second sprocket through a first chain, and the second sprocket is fixed on the first shaft. A third sprocket is also provided on the first shaft, and the third sprocket is connected to the fourth sprocket through a second chain. A toggle member is provided on the second chain for toggling a shifting vehicle with a sand mold to move on the connecting track. The driving device of the utility model has a simple structure, and the shifting vehicle can be automatically driven to move by using a toggle member, without moving the sand mold to avoid damage. However, the patent still has some defects: According to the model of this patent, the sand mold can only be moved a short distance, so the drying box must be set very close. However, in actual use scenarios, professional drying rooms are set up separately and at a certain distance from the printing site. Therefore, the use of this patent is very limited; This patent does not take any protective measures for the sand mold during the process of moving the sand mold, leaving it completely exposed, so there is still a great hidden danger that the sand mold may be damaged.

The sand mold moving mechanism of the laser 3D printer can completely conceal the sand mold through the cooperation of the temporary storage bin 1 and the front guard plate 7, thereby avoiding exposure of the sand mold and playing a good protective role, thereby effectively preventing the sand mold from being damaged. The pushing part 4 can carry the sand mold and can smoothly push it outward when it is needed to be taken out, thereby improving intelligence and reducing work burden while avoiding damage to the sand mold caused by manual movement, thereby effectively reducing the possibility of damage to the sand mold. The inner stopper 5 can be used to hold the sand mold together toward the center, thereby limiting the position of the sand mold to prevent it from shaking and colliding during transportation, thereby ensuring the stability of the sand mold. The sand mold is located on the pushing part 4, and the hot drying part 6 can keep the sand mold in a high temperature and dry environment during the process of moving and transporting the sand mold, so that the sand mold can be dried to a certain extent before entering the professional drying room, thereby ensuring that the strength of the sand mold can be improved at a certain rate during the movement, further preventing the sand mold from being damaged, and the moving component 3 can effectively absorb the vibration during walking while achieving overall flexible movement, thereby ensuring that the impact of vibration on the sand mold is minimized; the sand mold moving mechanism of the laser 3D printer has a good protective effect on the sand mold, a high safety level, and can effectively avoid damage to the sand mold, so it can adapt to different lengths of moving distances of the sand mold, has high compatibility, and has a good actual use effect; The moving assembly 3 includes a shock absorber 31, a transition plate 32 and a universal wheel 33; The plurality of shock absorbers 31 are respectively installed at the four corners of the bottom of the adjustment seat 2, the plurality of transition plates 32 are respectively installed on the plurality of shock absorbers 31, and the plurality of universal wheels 33 are respectively installed on the plurality of transition plates 32, so as to ensure that the sand mold moving mechanism of the laser 3D printer can be flexibly moved as a whole through the plurality of universal wheels 33, thereby ensuring that it is not limited by distance; the plurality of shock absorbers 31 continuously and effectively absorbs the vibration during the movement, thereby ensuring the stability of the above parts of the moving component 3 during the movement, and preventing the sand mold in the temporary storage bin 1 from shaking or even loosening due to excessive vibration.

In the process of placing the sand mold on the bearing panel 45, the entry of the sand mold squeezes the top plates 53 on both sides backwards, thereby compressing all the springs 54. After the sand mold is in place, the compressed springs 54 on both sides also press the sand mold tightly through the corresponding top plates 53, thereby realizing the positioning of the sand mold, limiting the displacement of the sand mold, and then ensuring the stability of the sand mold. After the sand mold is placed in place, the front guard plate 7 is closed to make the sand mold completely hidden in the temporary storage bin 1 and the front guard plate 7; when the top plate 53 is squeezed and the spring 54 is compressed, the corresponding inner support column 52 is pressed into the outer sleeve rod 51, providing support for the spring 54 without affecting the normal elasticity of the spring 54 to prevent the spring 54 from collapsing.
