Description

Technical Field

[0001] This utility model belongs to the field of advertising letter clamping technology, specifically relating to a special clamp for injecting glue into advertising letters. Background Technology

[0002] With the booming development of the advertising industry, advertising signs, as an important element of advertising, have seen a continuous increase in market demand. The types of advertising signs are becoming increasingly diverse, encompassing illuminated signs, non-illuminated signs, and other types, and materials including metal, plastic, and acrylic. In the manufacturing process of advertising signs, glue injection is one of the key steps; it not only enhances the structural strength of the signs but also serves to seal, waterproof, and enhance their appearance.

[0003] Currently, the glue injection process for advertising letters is developing towards automation, efficiency, and high precision. The application of automated glue injection equipment improves production efficiency and reduces errors caused by manual operation; efficient glue injection materials and processes shorten the production cycle; and high-precision glue injection requirements ensure the quality and appearance of the advertising letters. However, achieving these goals requires a stable and reliable specialized fixture to hold the advertising letter mold in place, ensuring the smooth progress of the glue injection process.

[0004] Many existing clamps use simple fixing methods, typically employing clips or spring clips to secure the lettering templates. This method is poorly adaptable to lettering templates of varying shapes and sizes. Most existing clamps are fixed structures, unable to be precisely adjusted according to the actual position and size of the lettering template. Installing the lettering template requires significant time for manual adjustments, and the accuracy of these adjustments is difficult to guarantee. Furthermore, when producing lettering of different specifications, different models of clamps may need to be used, increasing production costs and time. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a special clamp for injecting adhesive into advertising lettering. The lettering mold is placed inside a fixed frame, and a position adjustment mechanism allows the clamp to flexibly hold lettering molds of different sizes. This solves the problem that existing clamps use simple clips or spring clips to fix the lettering molds, which are less adaptable to different shapes and sizes.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a special clamp for injecting glue into advertising characters, used to fix the advertising character mold on the casting platform, including a fixed frame, a fixing clamp for clamping the outer periphery of the advertising character mold is movably arranged on the fixed frame, and a position adjustment mechanism for adjusting the position of the fixing clamp is arranged around the fixed frame.

[0007] Preferably, the fixing fixture includes a clamping rod movably mounted on the fixing frame, and a pressure rod mechanism is provided at the top of the clamping rod.

[0008] Preferably, the pressure bar mechanism includes a fixed sleeve rod disposed at the top of the clamping rod, a clamping block connected to the top of the fixed sleeve rod, and a universal joint connecting the clamping block and the fixed sleeve rod.

[0009] Preferably, the clamping rod is a threaded rod, and the tail end of the clamping rod is provided with a square or hexagonal connecting post.

[0010] Preferably, the fixing frame has a U-shaped structure, and a number of positioning holes are equally spaced on both sides of the U-shaped groove surrounding the fixing frame.

[0011] Preferably, the position adjustment mechanism includes a plurality of fixing nuts that are equidistantly arranged around the perimeter of the fixing frame and are threaded to match the clamping rod, with each fixing nut corresponding to a positioning hole on the inner sidewall of the U-shaped groove of the fixing frame.

[0012] Preferably, a rubber pad is provided at the top of the clamping block.

[0013] Preferably, the fixing frame, clamping rod, and pressure rod mechanism are all made of metal.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by placing the advertising letter mold inside the fixed frame and using the position adjustment mechanism set thereon, the fixing clamp can flexibly clamp advertising letter molds of different specifications without spending a lot of time on manual adjustment, thus reducing production costs and production cycle.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of the invention. Attached Figure Description

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0022] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a special clamp for injecting glue into advertising letters is used to fix the advertising letter mold on the pouring platform. It includes a fixed frame 1, a fixing clamp 2 for clamping the outer periphery of the advertising letter mold is movably arranged on the fixed frame 1, and a position adjustment mechanism 3 for adjusting the position of the fixing clamp 2 is arranged around the fixed frame 1.

[0023] This utility model proposes a special clamp for injecting glue into advertising letters. The fixing frame 1 is the basic frame structure of the entire special clamp, which plays the role of bearing and supporting other components, providing a basic platform for subsequent installation and fixing of other components, and is used to place on the casting platform to provide a stable support environment for fixing the advertising letter mold.

[0024] The fixing clamp 2 is movably set on the fixing frame 1 and directly clamps the outer periphery of the advertising letter mold, ensuring that the advertising letter mold remains stable during the glue injection process and will not move or shift, thereby ensuring the accuracy of glue injection and the quality of advertising letter production.

[0025] The position adjustment mechanism 3 is set around the fixed frame 1 to adjust the position of the fixing clamp 2 on the fixed frame 1. By operating the position adjustment mechanism 3, the fixing clamp 2 can be adjusted to a suitable position according to different sizes and shapes of advertising letter molds, so as to achieve effective clamping of various advertising letter molds.

[0026] When using this special fixture for gluing advertising lettering, first place the fixing frame 1 on the pouring platform to ensure its stability. Then, according to the size and shape of the advertising lettering mold to be fixed, operate the position adjustment mechanism 3 around the fixing frame 1. The position adjustment mechanism 3 will move the fixing clamp 2, which is movably mounted on the fixing frame 1, adjusting the fixing clamp 2 to a suitable position that can accurately clamp the outer periphery of the advertising lettering mold. Once the fixing clamp 2 reaches the appropriate position, place the advertising lettering mold on the fixing frame 1, and let the fixing clamp 2 clamp and fix the outer periphery of the advertising lettering mold, ensuring that the advertising lettering mold will not shake or shift during the gluing process, thus smoothly carrying out the gluing process for advertising lettering.

[0027] Combination Figure 2 , Figure 3 and Figure 4 As shown, the fixing clamp 2 includes a clamping rod 4 movably mounted on the fixing frame 1, and a pressure rod mechanism 5 is provided at the top of the clamping rod 4.

[0028] Specifically, the clamping rod 4 is movably mounted on the fixed frame 1. The clamping rod 4 can move within a certain range on the fixed frame 1, such as moving, rotating, or swinging to a certain extent, so that it has the ability to flexibly adjust its position to adapt to advertising letter molds of different sizes and shapes.

[0029] The fixed clamp 2 supports the pressure rod mechanism 5 and guides the pressure rod mechanism 5 to a suitable position to clamp the advertising letter mold. Through its own movable characteristics, the position can be adjusted in the horizontal or vertical directions, thereby changing the relative position of the pressure rod mechanism 5 with respect to the advertising letter mold.

[0030] The pressure bar mechanism 5 is located at the top of the clamping rod 4 and is fixedly connected to the clamping rod 4 or connected through an adjustable connection.

[0031] The pressure bar mechanism 5 is made of a material with a certain strength and hardness, such as metal (e.g., stainless steel, aluminum alloy) or high-strength engineering plastic, to ensure sufficient pressure is provided during clamping without deformation. The pressure bar mechanism 5 directly contacts the letter mold, applying pressure to fix the letter mold to the casting platform, preventing movement, shaking, or displacement of the mold during glue injection, thus ensuring the accuracy of glue injection and the quality of the advertising letter production.

[0032] When using the fixing clamp 2 to fix the advertising letter mold, first adjust the position of the clamping rod 4 on the fixing frame 1 according to the position and size of the advertising letter mold. Since the clamping rod 4 is movably set on the fixing frame 1, it can be moved to a suitable position by pushing, pulling or rotating, so that the pressure rod mechanism 5 is approximately above or to the side of the part of the advertising letter mold that needs to be clamped.

[0033] Next, the position and angle of the pressure bar mechanism 5 are further adjusted to ensure it conforms to the outer surface of the advertising letter mold. Then, by applying external force, the pressure bar mechanism 5 exerts sufficient pressure on the advertising letter mold, firmly fixing it to the casting platform. During the glue injection process, the advertising letter mold remains stable due to the continuous clamping action of the pressure bar mechanism 5, thus ensuring the smooth progress of the glue injection process and the quality of the advertising letter production.

[0034] Combination Figure 2 , Figure 3 and Figure 4 As shown, the pressure rod mechanism 5 includes a fixed sleeve rod 51 disposed at the top of the clamping rod 4, a clamping block 52 connected to the top of the fixed sleeve rod 51, and a universal joint 53 connected between the clamping block 52 and the fixed sleeve rod 51.

[0035] Specifically, the fixed sleeve 51 is fixedly installed at the top of the clamping rod 4. It is the basic support component of the pressure rod mechanism 5 and serves to connect the clamping rod 4 with other components above it, transmitting the movement and support force of the clamping rod 4 to other parts of the pressure rod mechanism 5.

[0036] The clamping block 52 is connected to the top of the fixing sleeve 51 via a universal joint 53. It is the part that directly contacts the advertising letter mold and is responsible for applying clamping force to fix the letter mold. The shape design of the clamping block 52 needs to be determined according to the common shape of the advertising letter mold and the clamping requirements. For example, if the advertising letter mold is mostly flat or nearly flat, the clamping block 52 can be designed as a rectangular or square flat plate; if the letter mold has a curved surface, the clamping block 52 can be designed as a curved block to match it. In terms of size, it is necessary to ensure sufficient contact area to provide a stable and reliable clamping force, while not being too large to affect operation and cooperation with other components.

[0037] The universal joint 53 connects the top of the fixed sleeve 51 and the clamping block 52, and is a key component that enables the clamping block 52 to rotate flexibly at multiple angles. The universal joint 53 allows the clamping block 52 to rotate and swing in multiple directions, thereby achieving a good fit between the clamping block 52 and the surface of the advertising lettering.

[0038] When clamping and fixing the advertising letter mold, first adjust the position of the clamping rod 4 on the fixing frame 1 so that the fixing sleeve 51 is approximately close to the part of the advertising letter mold that needs to be clamped. Then, due to the presence of the universal joint 53, the clamping block 52 can freely rotate and adjust according to the shape and angle of the advertising letter mold surface. The operator can manually push or rotate the clamping block 52 to make it fit tightly against the surface of the letter mold. Regardless of whether the surface of the letter mold is flat, curved, or has other complex shapes, the universal joint 53 can make the clamping block 52 adapt and achieve the best contact state.

[0039] Once the clamping block 52 is adjusted to the appropriate position and in close contact with the letter mold surface, pressure is applied to the fixing sleeve 51. This pressure is transmitted to the clamping block 52 through the universal joint 53, ensuring that the clamping block 52 generates sufficient clamping force on the letter mold and firmly fixes it to the casting platform. During the glue injection process, because the clamping block 52 is in close contact with the letter mold surface and a stable clamping force is applied, it effectively prevents the letter mold from moving, shaking, or shifting, thereby ensuring the smooth progress of the glue injection process and the quality of the advertising letter production.

[0040] Combination Figure 2 , Figure 3 and Figure 4 As shown, the clamping rod 4 is a threaded rod, and a square or hexagonal connecting post 41 is provided at the tail end of the clamping rod 4.

[0041] Specifically, clamping rod 4 adopts a threaded rod design. A threaded rod is a rod with helical threads on its surface, a structural feature that gives it unique performance and applications. The threaded rod is usually made of metals with a certain strength and hardness, such as stainless steel or carbon steel, to ensure that it will not deform or be damaged when subjected to external forces, and can stably transmit force and achieve position adjustment.

[0042] The connecting post 41 is located at the tail end of the clamping rod 4, that is, the other end opposite to the clamping end. It is square or hexagonal. This shape is designed to facilitate cooperation with corresponding operating tools (such as wrenches). The square or hexagonal structure allows the operating tool to better grip the connecting post 41, thereby applying torque and realizing the rotation operation of the clamping rod 4.

[0043] Combination Figure 1 , Figure 2 and Figure 3 As shown, the fixed frame 1 has a U-shaped structure, and several positioning holes 6 are equally spaced on both sides of the U-shaped groove surrounding the fixed frame 1.

[0044] Specifically, the fixing frame 1 adopts a U-shaped structure design. This shape is open, with one end open and the other end closed or semi-closed. The U-shaped structure provides a specific spatial layout for the placement of the advertising lettering template and subsequent clamping operations, making it convenient to place the template in the U-shaped groove for fixation.

[0045] Positioning holes 6 are equally spaced on both sides of the U-shaped groove surrounding the fixing frame 1. Multiple positioning holes 6 are distributed on the left and right side walls of the U-shaped groove according to the same spacing rule.

[0046] When precise fixing of the advertising letter mold according to its size and position is required, the positioning holes 6 on both sides of the U-shaped groove of the fixing frame 1 are used. A suitable positioning hole 6 can be selected to fix the clamping rod 4 to the fixing frame 1. Since the positioning holes 6 are equidistant, the operator can flexibly select different positions of the positioning holes 6 according to the actual size of the letter mold to adjust the installation position of the clamping rod 4. This ensures that the pressure rod mechanism 5 at the top of the clamping rod 4 can accurately clamp the letter mold; for larger letter molds, the outermost positioning hole 6 is selected for installation.

[0047] Combination Figure 1 , Figure 2 and Figure 3 As shown, the position adjustment mechanism 3 includes several fixing nuts 31 that are threadedly matched with the clamping rod 4 and are equidistantly arranged around the fixed frame 1. Each fixing nut 31 corresponds to a positioning hole 6 on the inner side wall of the U-shaped groove of the fixed frame 1.

[0048] Specifically, several fixing nuts 31 are evenly spaced around the fixed frame 1. This even distribution ensures that the clamping rod 4 has relatively uniform adjustment capability and support stability in all directions. No matter where the advertising lettering is placed within the fixed frame 1, the clamping rod 4 can be effectively adjusted using the appropriate fixing nuts 31.

[0049] Each fixing nut 31 has internal threads that match those of the clamping rod 4. The clamping rod 4 is a threaded rod, and when the clamping rod 4 passes through the fixing nut 31, the two engage through the threads, allowing the clamping rod 4 to rotate within the fixing nut 31 and move axially.

[0050] Each retaining nut 31 corresponds to a positioning hole 6 on the inner sidewall of the U-shaped groove of the retaining frame 1. During installation and adjustment, the position of the retaining nut 31 and the positioning hole 6 are interrelated, jointly determining the final position of the clamping rod 4. The positioning hole 6 may be used for auxiliary positioning or connection with other components to further enhance the stability of the clamping rod 4.

[0051] Combination Figure 2 , Figure 3 and Figure 4 As shown, a rubber pad 521 is provided at the top of the clamping block 52.

[0052] Specifically, the rubber pad 521 is positioned at the top of the clamping block 52, on the side that directly contacts the lettering. It is made of rubber, which possesses good elasticity, flexibility, and abrasion resistance. Common rubber materials include natural rubber, nitrile rubber, and silicone rubber. Different materials have different properties, and the appropriate material can be selected based on the specific usage environment (such as whether it comes into contact with chemicals, temperature range, etc.). The shape of the rubber pad 521 is usually adapted to the shape of the top of the clamping block 52, and may be flat, curved, or other special shapes to ensure full contact with the surface of the lettering. Its size is determined based on the size of the top of the clamping block 52 and the required contact area; generally, it should be able to completely cover the area where the top of the clamping block 52 contacts the lettering to provide uniform clamping pressure.

[0053] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixed frame 1, the clamping rod 4, and the pressure rod mechanism 5 are all made of metal.

[0054] Specifically, since the fixed frame 1, clamping rod 4, and pressure rod mechanism 5 are all made of metal, they possess high strength and rigidity, enabling them to resist the influence of external forces and maintain their shape and position. The good toughness of the metal material also ensures that the entire clamping system will not be easily damaged when subjected to accidental impacts, allowing it to continue to stably clamp the advertising letter mold, ensuring the smooth progress of the advertising letter manufacturing process and guaranteeing the production quality of the advertising letter.

[0055] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
