DETAILED DESCRIPTION

[0020] The embodiments of the present application will be described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application. All other examples obtained by those skilled in the art without creative labor are within the scope of the present application.

[0021] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 , a character mold fixing device for pouring light-emitting advertising characters includes a rack 1, which serves as the supporting foundation of the entire system, ensuring that it can withstand various external forces and pressures without deformation or damage during the pouring process.

[0022] A pouring platform 2 is provided on the rack 1, which ensures that the pouring material can be evenly distributed and smoothly solidified, thereby producing high-quality light-emitting advertising characters.

[0023] A top plate 3 is provided above the pouring platform 2, and a character mold fixing device 4 is provided between the pouring platform 2 and the top plate 3. The top plate 3 not only provides additional structural support for the entire device, but also serves as a fixed point for the character mold fixing device 4. The space between the top plate 3 and the pouring platform 2 accommodates the character mold fixing device 4 and the pouring character mold 5 fixed thereto, providing a closed and controlled environment for pouring operations. The top end of the character mold fixing device 4 abuts the top plate 3, and the fixing assembly 43 is used to abut the top plate 3 tightly, thereby fixing the top of the character mold fixing device 4. The bottom end of the character mold fixing device 4 abuts the top of the pouring character mold 5 and fixes it on the pouring platform 2.

[0024] The character mold fixing device 4 includes a main rod body 41, which serves as the main structure for connecting and supporting other components. One end of the main rod body 41 is connected to a telescopic rod 42 that can be extended, and the length of the telescopic rod 42 can be adjusted according to actual needs to ensure that the character mold fixing device 4 can adapt to pouring character molds 5 of different sizes and shapes.

[0025] The top of the telescopic rod 42 is equipped with a fixing component 43 for contacting the top plate 3, which allows workers to easily lock the letter mold fixing device 4 in the desired position. The bottom of the main rod 41 is equipped with a pressing mold component 44 for fixing the cast letter mold 5 onto the casting platform 2. The pressing mold component 44 is the part that directly contacts the letter mold fixing device 4 and the cast letter mold 5, and its shape and size match the top of the cast letter mold 5. When the telescopic rod 42 extends downwards, the pressing mold component 44 presses firmly against the top of the cast letter mold 5, securing it securely to the casting platform 2. This not only ensures the stability of the cast letter mold 5 during the casting process but also effectively prevents leakage and waste of casting materials.

[0026] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the molding assembly 44 includes a first connecting rod 441 disposed at the bottom end of the main rod 41. The first connecting rod 441 serves as a bridge connecting the main rod 41 and the fixed pressure plate 442, ensuring sufficient strength and stability. The bottom end of the first connecting rod 441 is connected to the fixed pressure plate 442, which matches the top of the cast-in-place mold 5 to ensure that pressure can be applied comprehensively and evenly, preventing slippage or displacement during the casting process.

[0027] To further enhance the stability and support of the fixed pressure plate 442, auxiliary support mechanisms 443 are provided on both sides of the bottom of the fixed pressure plate 442. The auxiliary support mechanisms 443 automatically deploy when the fixed pressure plate 442 contacts the cast-in-place mold 5, providing additional support for the fixed pressure plate 442. This not only improves the overall stability of the mold assembly 44 but also helps to distribute pressure, reducing excessive local pressure from the fixed pressure plate 442 on the cast-in-place mold 5, thereby protecting the cast-in-place mold 5 from damage.

[0028] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary support mechanism 443 includes spring connecting rods 4431 disposed on both sides of the bottom of the fixed pressure plate 442. The spring connecting rods 4431 can flexibly adapt to the casting molds 5 of different heights and provide necessary support when the fixed pressure plate 442 applies pressure. The spring connecting rods 4431 ensure that they can maintain a stable shape when subjected to pressure, avoiding excessive bending or deformation.

[0029] The bottom end of the spring connecting rod 4431 is connected with a rubber pad 4432. The rubber pad 4432 ensures good performance during long-term use. The main function of the rubber pad 4432 is to increase the contact area with the pouring platform 2 or the bottom of the pouring character mold 5, thereby dispersing the pressure and reducing the risk of local excessive compression. At the same time, the rubber pad 4432 also has certain anti-skid performance, which helps to prevent the pouring character mold 5 from sliding or shifting during pouring.

[0030] The combination of the spring connecting rod 4431 and the rubber pad 4432 enables the auxiliary support mechanism 443 to provide more uniform and stable support when the fixed pressing plate 442 exerts pressure. Not only does it improve the overall stability and applicability of the pressing mold assembly 44, but it also helps to protect the pouring character mold 5 from damage, ensuring that the final light-emitting advertising characters have high quality and precision.

[0031] In combination with Figure 2 , Figure 3 , Figure 4 and Figure 5 , the fixed assembly 43 includes a second connecting rod 431 arranged at the top end of the telescopic rod 42. The second connecting rod 431 not only ensures sufficient strength to withstand the pressure from the telescopic rod 42, but also ensures a tight connection with the telescopic rod 42, preventing loosening or falling off during pouring.

[0032] The top end of the second connecting rod 431 is connected with a fixed pressing block 432. The fixed pressing block 432 matches the contact surface of the top plate 3 to ensure that pressure can be applied comprehensively and uniformly. The fixed pressing block 432 ensures good performance during long-term use. At the same time, the surface of the fixed pressing block 432 is increased with anti-skid texture or coating to improve the friction between the top plate 3, preventing sliding or shifting during pouring.

[0033] To further enhance the stability and adaptability of the fixed assembly 43, the design of the fixed pressing block 432 can also consider adding a fine adjustment mechanism. The fine adjustment mechanism allows workers to make minor adjustments to the position of the fixed pressing block 432 after it contacts the top plate 3, to ensure that it can completely fit the surface of the top plate 3, reducing uneven pressure caused by unevenness or errors. Not only does it improve the flexibility and applicability of the fixed assembly 43, but it also helps to protect the top plate 3 from damage and prolong its service life.

[0034] In combination with Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the connection between the second connecting rod 431 and the fixed block 432 is connected through a universal joint. The universal joint, also known as a universal joint or universal coupling, is a connecting component that allows relative rotation between two shafts or a shaft and a housing within a certain angular range. In the fixed assembly 43, the universal joint is ingeniously arranged between the second connecting rod 431 and the fixed block 432. Due to the possibility of slight unevenness or inclination of the surface of the top plate 3 caused by manufacturing errors, long-term use caused by wear or improper installation, traditional rigid connection may not ensure full and uniform contact between the fixed block 432 and the top plate 3. After using the universal joint, the fixed block 432 can be adjusted within a certain range to adapt to the actual surface condition of the top plate 3, ensuring that the applied pressure is more uniform and reducing the risk of uneven pressure or local excessive compression caused by poor contact. The second connecting rod 431 and the fixed block 432 connected by the universal joint are more convenient during installation and adjustment. Workers can easily adjust the position and angle of the fixed block 432 by rotating the universal joint to ensure its close fit with the top plate 3. Not only does it improve installation efficiency, but it also helps reduce the failure rate caused by improper installation.

[0035] In combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the main rod body 41 is provided with a fixed hole 411, which is located at an appropriate position of the main rod body 41 to ensure that the adjusting bolt can be tightly and firmly inserted into it, tightly connecting the main rod body 41 and the telescopic rod 42 together. Not only does it improve the stability of the connection, but it also helps prevent loosening or falling off caused by excessive force during pouring.

[0036] The telescopic rod 42 is provided with a plurality of equally spaced adjusting holes 421, and the main rod body 41 and the telescopic rod 42 are fixed by adjusting the total length of the main rod body 41 and the telescopic rod 42 through adjusting bolts. The adjusting holes 421 are uniformly distributed along the length direction of the telescopic rod 42, so that workers can select appropriate adjusting holes 421 to align with the fixed holes 411 on the main rod body 41 according to actual needs, and fix them through adjusting bolts. By changing the position of the selected adjusting hole 421 on the telescopic rod 42, the total length of the main rod body 41 and the telescopic rod 42 can be easily adjusted to adapt to different sizes and shapes of the pouring character mold 5.

[0037] In actual operation, workers only need to slide the telescopic rod 42 to the desired position, select the corresponding adjusting hole 421 to align with the fixed hole 411, and then tighten the adjusting bolt to complete the adjustment. Not only is it simple and fast, but it also has high precision and stability, which can ensure that the character mold fixing device 4 always maintains stable form and performance during pouring.

[0038] In combinationFigure 1 、 Figure 2 and Figure 3 As shown in

[0039] The first connecting rod 441 and the second connecting rod 431 are both threaded rods, and the threaded rod design is matched with the adjusting nut 45 to provide a more precise and flexible adjustment mode for the first connecting rod 441 and the second connecting rod 431.

[0040] Specifically, the first connecting rod 441 serves as a bridge connecting the main rod body 41 and the fixed pressing plate 442, and the threaded design allows the staff to accurately control the length of the first connecting rod 441 extending out of the bottom end of the main rod body 41 by rotating the adjusting nut 45. Not only is it simple and efficient, but it also has high precision, which can ensure the close contact between the fixed pressing plate 442 and the casting character mold 5, thereby effectively preventing sliding or displacement during casting. At the same time, the locking function of the adjusting nut 45 can also ensure that the first connecting rod 441 maintains a stable form when under pressure, preventing the fixed pressing plate 442 from failing due to loosening.

[0041] The second connecting rod 431 also adopts a threaded rod design and adjusts its length extending out of the top end of the telescopic rod 42 through the adjusting nut 45. This allows the fixed pressing block 432 to tightly contact the top plate 3, ensuring the overall stability of the character mold fixing device 4. Similar to the first connecting rod 441, the adjustment of the second connecting rod 431 also has high precision and flexibility, which can adapt to top plates 3 of different heights and sizes, ensuring that the fixed assembly 43 can accurately contact and apply stable pressure to the top plate 3.

[0042] In actual operation, the staff only needs to rotate the adjusting nut 45 to easily adjust the length of the first connecting rod 441 and the second connecting rod 431. Not only is it simple and intuitive, but it also has high efficiency and precision, which can greatly shorten the installation and adjustment time and reduce the operation difficulty and maintenance cost.

[0043] In combination with Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in order to ensure that the fixed process will not cause damage to the matrix or the top plate 3, the fixed pressing plate 442 and the fixed pressing block 432 are provided with soft pads. The soft pad is usually made of a material with high elasticity, wear resistance, corrosion resistance and certain anti-skid performance. These materials not only can effectively disperse the pressure, reduce the friction and wear caused by direct contact, but also can provide additional cushioning effect, protect the matrix and the top plate 3 from external impact and vibration.

[0044] The preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the utility model disclosed in the technical range, according to the utility model technical scheme and its utility model concept are equivalent to replace or change, all should be covered in the protection scope of the utility model.
