Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, and more specifically, it relates to a tracking sand mold 3D printing device. Background Technology

[0002] Sand mold 3D printers use fine sand as the base material and binder for shaping. By layering a very thin layer of sand onto the printing tray, and then spraying the binder onto the sand layer in the program-defined area, the printing tray sinks to a certain depth after curing, so that sand can be laid again. By repeating the above steps, relatively complex three-dimensional structures can be formed. The printed products are mainly used for casting or producing handicrafts.

[0003] In existing systems, both the print head and the sand spreader move on the same horizontal plane on the frame surface. When the print head and the sand spreader are moving, the drive components of the print head and the sand spreader will inevitably malfunction or become uncontrollable, which will cause the print head and the sand spreader to collide. However, there is no buffer structure between the print head and the sand spreader in the current system, which will cause damage to the print head and the sand spreader and affect the performance of the 3D printing device. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tracking sand mold 3D printing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A tracking sand mold 3D printing device includes a frame with a printing table. Two parallel guide rails are arranged on both the front and rear sides of the upper surface of the frame. Two guide rail mounting brackets are slidably connected to the two guide rails. A print head is positioned between the two inner front and rear guide rail mounting brackets, and a sand spreader is positioned between the two outer front and rear guide rail mounting brackets. Two mounting blocks are positioned on the opposing surfaces of the two left and right guide rail mounting brackets. A buffer plate is positioned on an adjacent side of each mounting block. A buffer cavity is formed within each mounting block. A buffer rod is positioned on the surface of the buffer plate near the mounting block. The other end of the buffer rod slides through the buffer cavity. An internal sliding plate is positioned at the end of the buffer rod located within the buffer cavity, sliding within the buffer cavity. A tension spring is movably sleeved on the outer surface of the buffer rod between the internal sliding plate and the inner wall of the buffer cavity.

[0007] The present invention is further configured such that: a deceleration push rod is provided on the side of the buffer slide cavity away from the built-in slide plate, the lower end of the deceleration push rod slides through the lower surface of the mounting block, and a deceleration plate is provided at the lower end of the deceleration push rod.

[0008] The present invention is further configured such that: the speed reduction plate can contact the upper surface of the frame, and a friction plate is provided on the lower surface of the speed reduction plate.

[0009] The present invention is further configured such that: a sleeve rod is provided on the inner wall of the buffer cavity away from the built-in slide plate, and a contact rod is slidably sleeved on the outer surface of the sleeve rod near the end of the built-in slide plate, so that the built-in slide plate can contact the contact rod.

[0010] The present invention is further configured such that a spring is movably sleeved on the outer surface of the sleeve rod between the contact rod and the inner wall of the buffer slide cavity.

[0011] The present invention is further configured such that: the lower surface of the contact rod and the upper surface of the deceleration push rod are both provided with hinge seats, and a rotating push plate is hinged between the two hinge seats.

[0012] The present invention is further configured such that the two buffer plates on the left and right sides can contact each other.

[0013] The advantages of this utility model are:

[0014] Firstly, this utility model achieves tracking printing by coordinating the movement of the print head and the sand spreader, which significantly improves printing efficiency. At the same time, the addition of a buffer structure minimizes the risk of the print head and sand spreader colliding and being damaged, thus ensuring the safety of the printing device during operation.

[0015] Secondly, by setting up structures such as a speed reduction plate, this utility model allows the speed reduction plate to contact the surface of the frame after the buffer plate is compressed a certain distance, further improving the buffering effect on the print head and the sand spreader.

Detailed Implementation

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] Specifically, it refers to a tracking sand mold 3D printing device, including a frame 1, on which a printing table is mounted. Two parallel guide rails 2 are mounted on the front and rear sides of the upper surface of the frame 1. Two guide rail mounting brackets 3 are slidably connected to the two guide rails 2. A print head 4 is positioned between the two guide rail mounting brackets 3 closest to the printing table, and a sand spreader 5 is positioned between the two guide rail mounting brackets 3 furthest from the printing table. During use, a 3D printing speed control model is established by collecting, organizing, and analyzing historical data. Based on the model analysis, the coordinated movement of the print head 4 and the sand spreader 5 is achieved, transforming the previous separate movement of the print head 4 and the sand spreader 5 into coordinated movement, realizing tracking printing with simultaneous sand spreading and curing, significantly improving printing efficiency.

[0025] Two mounting blocks 6 are provided on the opposite surfaces of the two guide rail mounting brackets 3. A buffer plate 7 is provided on the adjacent side of the two mounting blocks 6. A buffer slide cavity 9 is provided in the mounting block 6. A buffer slide rod 8 is provided on the surface of the buffer plate 7 near the mounting block 6. The other end of the buffer slide rod 8 slides through into the buffer slide cavity 9. An internal sliding plate 10 is provided at the end of the buffer slide rod 8 located in the buffer slide cavity 9. A tension spring 11 is provided between the internal sliding plate 10 and the inner wall of the buffer slide cavity 9 and is movably sleeved on the outer surface of the buffer slide rod 8.

[0026] When the tension spring 11 is not under tension, it exerts a tension on the built-in slide plate 10, causing the initial position of the built-in slide plate 10 to be close to the outer side of the mounting block 6. At the same time, the buffer slide rod 8 pushes the buffer plate 7 away from the mounting block 6. When the print head 4 and the sander 5 move together, if the print head 4 or the sander 5 malfunctions and the distance between the print head 4 and the sander 5 exceeds the safe distance, the buffer plates 7 on the left and right guide rail mounting brackets 3 will contact each other. At the same time, the buffer plates 7 will shift to the side closer to the mounting block 6, and the buffer slide rod 8 will push the buffer plates 7 to slide in the buffer slide cavity 9. Meanwhile, the tension spring 11 will be stressed and stretched. In this way, the print head 4 and the sander 5 will be buffered and protected during their coordinated movement, minimizing the risk of damage from a collision between the print head 4 and the sander 5, and ensuring the safety of the printing device during operation.

[0027] A deceleration push rod 12 is provided on the side of the buffer cavity 9 away from the built-in slide plate 10. The lower end of the deceleration push rod 12 slides through the lower surface of the mounting block 6. A deceleration plate 13 is provided at the lower end of the deceleration push rod 12. When the deceleration push rod 12 moves down, the deceleration plate 13 can contact the upper surface of the frame 1. At the same time, a friction plate is provided on the lower surface of the deceleration plate 13. When the deceleration plate 13 slides and rubs against the upper surface of the frame 1, it can create a deceleration effect on the guide rail mounting frame 3, which further improves the buffering effect on the print head 4 and the sand spreader 5.

[0028] A sleeve rod 15 is provided on the inner wall of the buffer slide cavity 9 away from the built-in slide plate 10. A contact rod 14 is slidably sleeved on the outer surface of the sleeve rod 15 near the end of the built-in slide plate 10. The built-in slide plate 10 can contact the contact rod 14. A spring 16 is provided between the contact rod 14 and the inner wall of the buffer slide cavity 9 and is movably sleeved on the outer surface of the sleeve rod 15. A hinge seat 17 is provided on the lower surface of the contact rod 14 and the upper surface of the deceleration push rod 12. A rotating push plate 18 is hinged between the two hinge seats 17.

[0029] When the buffer plate 7 pushes the buffer slide rod 8 to one side of the buffer slide cavity 9, after the built-in slide plate 10 has been displaced for a period of time, the built-in slide plate 10 contacts the contact rod 14 and exerts a thrust on the contact rod 14, causing the contact rod 14 to slide on the surface of the sleeve rod 15. At the same time, the spring 16 is stressed and contracts. During the displacement of the contact rod 14, it exerts a thrust on the rotating push plate 18, causing the rotating push plate 18 to push the deceleration push rod 12 downward, so that the deceleration plate 13 contacts the upper surface of the frame 1, thereby achieving the purpose of buffering the print head 4 or the sand spreader 5 and improving the buffering effect on the print head 4 and the sand spreader 5.
