Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to a 3D printing wax mold forming device with a modular and detachable wax material container. Background Technology

[0002] Wax models are models made of wax and are widely used in casting and dentistry. First, a high-precision mold is made according to the shape and size of the casting to be made. It is usually made of aluminum and used to form wax models. There are two methods: hot press molding and rapid prototyping. Hot press molding involves injecting prepared liquid, paste, or cream wax into a mold under certain pressure. After solidification, the wax model is removed. Rapid prototyping technology includes stereolithography, selective laser sintering, fused deposition modeling, and layered solid manufacturing, which can directly produce wax models.

[0003] The production of wax models uses a 3D printing wax model forming device with a modular and detachable wax tank. This device uses 3D printing technology to store and supply wax with a modular and detachable wax tank. During operation, the wax is precisely stacked layer by layer on the forming platform according to the designed 3D model data, and finally the required wax model is formed.

[0004] In existing technology, this device uses 3D modeling software to design the three-dimensional model of the required wax model and converts it into a file format that the printer can recognize. According to the characteristics of the wax and the requirements of the wax model, appropriate printing parameters, such as temperature, speed, and layer thickness, are set. The wax tank containing the corresponding wax is installed on the printer and the connection is ensured to be firm. The printer extrudes the wax layer by layer and accumulates it on the forming platform according to the preset path and parameters until the entire wax model is printed. After printing, the wax model is cleaned and trimmed to meet the final usage requirements. However, nozzle positioning errors, uneven platform, and uneven wax extrusion can lead to dimensional deviations, surface roughness, and internal defects in the wax model. Currently, a double-sided synchronous drive and gantry structure are used to reduce motion deviations. However, some parts of the device rely on natural air cooling, which results in a very long cooling time for the wax model, seriously affecting production efficiency. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a modular, detachable wax container for 3D printing wax model forming, comprising a base 1, with fixed columns 2 fixedly connected to the four corners of the top wall of the base 1, and fixed plates 3 fixedly connected to the outer walls of the fixed columns 2. A cooling mechanism 6 is installed on the left side of the top wall of the base 1 to cool the wax model. Fixed mechanisms 7 are installed at the four corners of the bottom wall of the fixed plate 3, facilitating installation and disassembly. The cooling mechanism 6 includes a base. 602, base 602 is fixedly connected to the left side of the top wall of base 1. A connecting rod 610 is rotatably connected to the rear side of the top wall of base 602. Helical gears 611 are fixedly connected to both the left and right ends of connecting rod 610. Helical gears 603 are rotatably connected to both the left and rear sides of the top wall of base 602. A toothed disc 604 is mounted on the outer wall of helical gear 603. The toothed disc 604 is connected to base 602. A crank 612 is fixedly connected to the end of helical gear 603. A crank 606 is rotatably connected to the upper part of the outer wall of the second crank 612. A toothed disc 613 is fixedly connected to the end of the crank 612. The toothed disc 613 is connected to the toothed disc 604 via a hinge 605. A fixed frame 607 is rotatably connected to the upper part of the outer wall of the first crank 606. A drive assembly 601 is installed on the left side of the top wall of the base 602. The drive assembly 601 includes a motor 6011, which is fixedly connected to the left side of the inner wall of the fixed column 2. 11 The output end is fixedly connected to the connecting rod 6012. The connecting rod 6012 is rotatably connected to the left side of the top wall of the base 602. The front and rear sides of the outer wall of the connecting rod 6012 are fixedly connected to the helical gear 6013. The helical gear 6013 meshes with the helical gear 611. The front helical gear 6013 meshes with the helical gear 603. The right side of the outer wall of the fixed frame 607 is fixedly connected to the motor 608. The output end of the motor 608 is fixedly connected to the fan 609.

[0034] Specifically, the rotation of motor 6011 drives the rotation of connecting rod 6012, which in turn drives the rotation of helical gear 6013 on its outer wall. The front helical gear 6013 drives the rotation of helical gear 603, and the rear helical gear 6013 drives the rotation of helical gear 611. Helical gear 611 drives the rotation of connecting rod 610, thereby causing the rotation of helical gear 611 at the end of connecting rod 610, which in turn drives the rotation of helical gear 603 on the rear side of base 602. The second crank 603 drives the second crank 612 to rotate, and the rotation of the second crank 612 drives the first crank 606, so that the second serrated disk 613 on the outer wall of the first crank 606 is connected to the first serrated disk 604 through the hinge 605 to prevent the second crank 612 from falling off. The outer walls of both first cranks 606 are rotatably connected to the fixing brackets 607. The two first cranks 606 rotate back and forth, so that the fixing brackets 607 can move in all directions and at multiple angles, which allows the fan 609 to cool the wax mold in all directions and improve the cooling efficiency.

[0035] Reference Figure 1 , Figure 2 and Figure 6 The fixing mechanism 7 includes a fixing block 701, which is fixedly connected to the four corners of the bottom of the fixing column 2. A clamping block 705 is fixedly connected to the middle of the bottom wall of the fixing block 701. A locking assembly 702 is installed on the front side of the bottom wall of the fixing block 701. The locking assembly 702 includes a rotating shaft 7022, which is rotatably connected to the inner wall of the clamping block 705. A buckle 7023 is rotatably connected to the outer wall of the rotating shaft 7022. A damping rod 7021 is rotatably connected to the front side of the bottom wall of the fixing block 701. The damping rod 7021 is connected to the buckle 7023. A connecting block 704 is rotatably connected to the middle of the inner side of the clamping block 705. A bolt 703 is threadedly connected to the left side of the bottom wall of the connecting block 704.

[0036] Specifically, first rotate the buckle 7023, which rotates along the outer wall of the rotating shaft 7022. Then, the buckle 7023 compresses the damping rod 7021. Next, rotate the connecting block 704 so that the connecting block 704 is locked in the groove on the inner wall of the clamping block 705. Release the buckle 7023, which automatically rebounds due to the elasticity of the damping rod 7021, locking the buckle 7023 in the groove on the outer wall of the connecting block 704. Then, screw in the bolt 703 to fix the bolt 703 in the fixing post 2, connecting the fixing plate 3 and the fixing post 2 together. The operation is convenient, and it is easy to replace during maintenance and disassembly, shortening maintenance time and reducing maintenance costs.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The front left and right sides of the fixed column 2 are equipped with a compartment door 4. The front side of the outer wall of the compartment door 4 is fixedly connected with a handle 5. Multiple support columns 9 are fixedly connected at equal intervals on the right side of the top wall of the base 1. A printing platform 8 is installed in the upper middle part of the outer wall of the support column 9.

[0038] Specifically, the door 4 is connected to the fixed post 2 by a precision hinge. This hinge design is specially optimized, allowing for smooth opening and closing and excellent sealing. When closed, it fits tightly against the fixed post 2, preventing heat loss and wax spillage from the wax chamber. When wax needs to be replaced or the inside of the wax chamber needs to be cleaned and maintained, the operator can easily open the door 4 by simply holding the handle 5 to quickly and conveniently access the inside of the wax chamber, greatly improving the ease of operation. The printing platform 8, as the key part that supports the wax mold forming, is made of a high-precision machined flat metal plate with a polished surface, ensuring excellent adhesion and forming accuracy of the wax mold in the initial printing stage.

[0039] Working Principle: Motor 6011 starts rotating, and its rotational power is transmitted to connecting rod 6012 via a mechanical connection, causing connecting rod 6012 to rotate as well. Helical gear 6013 is installed on the outer wall of connecting rod 6012. As connecting rod 6012 rotates, helical gear 6013 also rotates. The front part of helical gear 6013 meshes with helical gear 603. Through gear transmission, the rotational power of helical gear 6013 is transmitted to helical gear 603, causing it to rotate as well. Simultaneously, the rear part of helical gear 6013 meshes with helical gear 611. Again, through gear transmission, the rotational power of helical gear 6013 is transmitted to helical gear 611, causing it to rotate. The rotation of helical gear 611 drives connecting rod 610 to rotate. Helical gear 611 is also installed at the end of connecting rod 610. As connecting rod 610 rotates, the helical gear at the end... Gear 3 611 also rotates, and through the gear transmission principle, transmits the rotational power to helical gear 2 603 on the rear side of base 602, causing it to continue rotating. The rotational power of helical gear 2 603 is further transmitted to crank 2 612, causing crank 2 612 to start rotating. The rotation of crank 2 612 is transmitted to crank 1 606 through a mechanical connection, so that the serrated disk 2 613 on the outer wall of crank 1 606 is connected to serrated disk 1 604 through hinge 605, thereby preventing crank 2 612 from falling off during rotation. A fixing bracket 607 is installed on the outer wall of both crank 1 606. As the two crank 1 606 rotate back and forth, the fixing bracket 607 can move in all directions and at multiple angles. This design allows the fan 609 to cool the wax model in all directions, greatly improving cooling efficiency and ensuring that the wax model cools evenly during the cooling process, avoiding deformation or other quality problems caused by excessive local temperature.

[0040] Rotate the buckle 7023, which rotates along the outer wall of the rotating shaft 7022. During rotation, the buckle 7023 compresses the damping rod 7021, providing necessary elastic support for subsequent connection operations. Next, rotate the connecting block 704 so that it accurately engages in the groove on the inner wall of the clamping block 705, ensuring the stability of the connection. After releasing the buckle 7023, due to the elasticity of the damping rod 7021, the buckle 7023 will automatically spring back and accurately engage in the groove on the outer wall of the connecting block 704, further reinforcing the connection. Finally, screw in the bolt 703 to firmly fix it in the fixing column 2, tightly connecting the fixing plate 3 and the fixing column 2 together. This design is not only convenient to operate, but also facilitates the replacement of parts during maintenance and disassembly, greatly shortening maintenance time, reducing maintenance costs, and improving the overall maintenance efficiency and economic benefits of the equipment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
