Description

Technical Field

[0001] This utility model relates to the field of autoclaved aerated concrete (AAC) production technology, and in particular to an AAC billet mold. Background Technology

[0002] In the field of autoclaved aerated concrete (AAC) production, the billet mold, as the core equipment for material forming, directly determines the product forming quality, production efficiency, and equipment lifespan through its structural rationality and functional stability. Currently, mainstream AAC billet molds on the market have gradually revealed several technical defects in practical applications, making it difficult to meet the demands of modern production for high efficiency, stability, and low loss. Specific problems are as follows: 1. Insufficient reliability of side panel fixing can easily lead to molding defects; Existing molds often use simple snap-fit ​​or bolt connections to fix the side plates. During concrete pouring and subsequent compaction, insufficient fixing strength or uneven stress can easily lead to side plate shifting or loosening. This directly causes molding defects such as grout leakage and missing corners on the sides of the billet. This not only requires additional manpower for later repairs, reducing product yield, but also causes grout leakage to contaminate equipment and the production environment, increasing cleaning and maintenance costs. Furthermore, traditional fixing methods are cumbersome, requiring significant time for each side plate removal and installation, severely hindering production cycle improvement.

[0003] 2. Demolding is difficult, affecting the integrity of the blank and the life of the mold; Because autoclaved aerated concrete (AAC) billets have strong adhesion to the mold's inner wall after molding, existing molds are generally not optimized for demolding and lack dedicated demolding aids or coatings. During demolding, external force is required to forcibly separate the billet from the mold, which easily leads to surface damage and cracking of the billet, especially for larger or more complex billets, where the damage rate is even higher. Furthermore, the friction generated by forced demolding exacerbates wear on the mold's inner wall, shortens mold lifespan, increases equipment replacement frequency, and raises production costs for enterprises.

[0004] 3. The mold has low movement and positioning accuracy and poor adaptability; The production of autoclaved aerated concrete (AAC) involves multiple processes, including pouring, vibration, and autoclaving, requiring frequent movement of molds between different machines. Existing mold movement mechanisms are mostly simple roller designs, lacking stable guiding and limiting structures. When moving along workshop tracks, they are prone to deviation and jamming, making it difficult to accurately position them at the designated positions on the vibration or autoclaving equipment. This not only affects the efficiency of process connections but may also lead to uneven vibration compaction due to positioning errors, further reducing the quality of the formed material. Furthermore, the support structures of some molds are poorly compatible with different models of vibration equipment, requiring additional adjustment components for use, increasing the cost of equipment versatility.

[0005] 4. The adjustment mechanism is inconvenient to operate, and its adaptability and stability are insufficient; To meet the production needs of blanks with different specifications, molds must have a certain degree of adjustability to change the internal forming space. Existing mold adjustment mechanisms (such as components for adjusting the side plate position) mostly use manual direct pushing or simple threaded structures. During adjustment, it is difficult to accurately control the movement distance and fit of the side plates, easily leading to asymmetry between the two side plates and affecting the dimensional accuracy of the blank. Furthermore, the adjustment mechanism lacks effective locking and limiting structures, making it prone to positional shifts due to vibration during mold operation, further exacerbating forming errors. The operation process is also time-consuming and labor-intensive, hindering production efficiency.

[0006] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a mold for autoclaved aerated concrete billets, making it more valuable for industrial use. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a mold for autoclaved aerated concrete billets.

[0008] This utility model discloses an autoclaved aerated concrete (AAC) billet mold, comprising a mold body with openings at the top and sides. The side openings of the mold body can cover a side plate supporting the billet. A pressing frame that can move back and forth is installed at the bottom of the mold body. The pressing frame can fasten the side plate to the side openings of the mold body. The inner wall of the mold body is covered with a release coating layer, which facilitates the demolding of the concrete billet.

[0009] This autoclaved aerated concrete (AAC) billet mold has a main body with openings at the top and sides. Side plates for supporting the billet can be installed at the side openings. The bottom of the main body is equipped with a clamping frame that can move back and forth. The clamping frame can securely fasten the side plates to the side openings, ensuring that the side plates will not loosen or shift during the billet forming process, effectively avoiding grout leakage. At the same time, the inner wall of the main body is coated with a release coating layer, which can significantly reduce the adhesion between the concrete billet and the inner wall of the mold, making the demolding process smoother, reducing billet damage, ensuring the integrity of the billet, and reducing wear on the mold.

[0010] Furthermore, a lead screw is movably mounted in the space at the bottom of the mold body via a bearing, and a bushing that mates with the end of the lead screw is installed on the inner bottom of the clamping frame.

[0011] Inside the space at the bottom of the mold body, a lead screw is movably mounted with the aid of bearings, while the inner bottom of the clamping frame is equipped with a bushing that can cooperate with the end of the lead screw. This structural design allows the clamping frame to move smoothly through the bushing when the lead screw rotates, thereby flexibly adjusting the clamping force of the clamping frame on the side plate. This not only ensures the reliability of the side plate fixation, but also makes the operation more convenient and labor-saving, effectively improving the flexibility and stability of the mold during use.

[0012] Furthermore, the other end of the lead screw is movably mounted on the vertical plate of the mold body via a bearing. After the tail end of the lead screw passes through the vertical plate of the mold body, a guide sleeve with an outwardly expanding outer end is fixed. Inside the guide sleeve is an integrally formed elongated limiting plate, which can cooperate with the corresponding locking head.

[0013] The other end of the lead screw is movably mounted on the vertical plate of the mold body via a bearing. After its tail end passes through the vertical plate, it is fixed with a guide sleeve that extends outward. The guide sleeve has an integrally formed elongated limiting plate inside. The limiting plate can cooperate with the corresponding locking head. Through this structural design, the lead screw can be stably locked after it is adjusted to the correct position, preventing it from shifting due to vibration or other factors during mold operation. This ensures that the clamping effect of the clamping frame on the side plate is always reliable and improves the overall working stability of the mold.

[0014] Furthermore, a limiting sleeve with a central through-hole is fixed at the bottom of the mold body, and a sliding rod that can be inserted into the limiting sleeve is located at the lower end of the clamping frame.

[0015] The bottom of the mold body is equipped with a centrally open limiting slide sleeve, and the lower end of the clamping frame is equipped with a slide rod that can be inserted into the limiting slide sleeve. The two work together to provide precise guidance for the movement direction of the clamping frame, preventing it from deviating or shaking during movement, ensuring that the clamping frame always runs smoothly along the preset trajectory, thereby ensuring accurate and uniform fastening position of the side plate, and improving the overall structural stability and operational reliability of the mold.

[0016] Furthermore, guide wheels that contact the sidewalls of the slide rod are movably mounted on both the upper and lower sides of the limiting sleeve via shafts.

[0017] Inside the limiting sleeve, on both the upper and lower sides, guide wheels that contact the side wall of the slide rod are movably mounted via shafts. These guide wheels can convert the sliding friction of the slide rod into rolling friction, greatly reducing the resistance between the two, making the slide rod move more smoothly and effortlessly within the limiting sleeve. At the same time, it can also reduce component wear, extend service life, and further ensure the stability and accuracy of the pressing frame movement process.

[0018] Furthermore, four support frames are fixed to the bottom of the mold body for support on the vibrating equipment.

[0019] The bottom of the mold body is equipped with four support frames to firmly support the mold on the vibration equipment. This design allows the mold to remain stable during vibration molding, avoiding displacement or shaking caused by vibration, ensuring uniform force on the blank, helping to improve the density and molding quality of the blank, and also enhancing the reliability of the mold and vibration equipment.

[0020] Furthermore, the coaxial support frames are connected by rollers that mate with the tracks laid in the workshop.

[0021] Between the support frames on the same axis, rollers that can cooperate with the workshop track are installed through the shaft. With the help of these rollers, the mold can move flexibly along the track, which facilitates the transfer between equipment in different production processes. This not only reduces the manpower consumption in the handling process, but also ensures that the movement process is smooth and stable, and improves the efficiency and convenience of production flow.

[0022] Furthermore, a downward-mounted friction frame is fixed at the bottom of the mold body, and the friction frame can cooperate with the drive wheel set on the vibration equipment.

[0023] The bottom of the mold body is equipped with a downward-extending friction frame, which can cooperate with the drive wheel on the vibration equipment. Through the action of the two, the power of the vibration equipment can be smoothly transmitted to the mold, ensuring that the mold obtains stable vibration force in the vibration molding process, promoting uniform and dense blanks, improving molding quality, and also enhancing the reliability and adaptability of power transmission between the mold and the vibration equipment.

[0024] By means of the above-described solution, the present invention has at least the following advantages: I. Enhance the reliability of side panel fixing, reduce molding defects, and improve production efficiency. By incorporating a movable clamping frame at the bottom of the mold body, coupled with a transmission structure of screw and bushing, precise and secure fastening of the side plates is achieved. When the screw rotates, it drives the clamping frame to move smoothly via the bushing, flexibly adjusting the fastening force. This avoids the problems of loosening and uneven force distribution associated with traditional snap-fit ​​or bolt connections, fundamentally reducing slurry leakage and corner chipping during billet pouring and vibration, significantly improving product qualification rate and reducing manpower investment for later repairs. Furthermore, compared to traditional cumbersome disassembly and assembly methods, this structure is more convenient and labor-saving, effectively shortening the side plate assembly and disassembly time, accelerating production cycle, and adapting to the needs of modern continuous production. In addition, the design of the guide sleeve at the tail end of the screw and the limiting plate ensures stable locking after adjustment, preventing positional displacement caused by vibration, further guaranteeing the continuity and reliability of the side plate fixing effect.

[0025] II. Optimize the demolding experience, ensure the integrity of the blank, and extend the mold life. The release coating layer covering the inner wall of the mold significantly reduces the adhesion between the concrete blank and the mold's inner wall, avoiding the need for forced demolding as with traditional molds. This makes the demolding process smoother, reducing surface damage and cracking of the blank, and is particularly effective in protecting the integrity of large or complex-structured blanks. Simultaneously, the reduced demolding resistance also decreases frictional wear on the mold's inner wall, extending the overall lifespan of the mold, reducing equipment replacement frequency, saving production costs for enterprises, and improving the cost-effectiveness of equipment use.

[0026] III. Improve movement and guiding accuracy, enhance process adaptability, and ensure molding quality. The mating structure between the bottom limiting sleeve of the mold and the sliding rod of the clamping frame provides precise guidance for the movement of the clamping frame, preventing offset and wobbling during movement. This ensures accurate and uniform clamping of the side plates, further guaranteeing the dimensional accuracy of the blank. The guide wheels on the upper and lower sides of the limiting sleeve convert the sliding friction of the sliding rod into rolling friction, reducing movement resistance, improving operational convenience, reducing component wear, and extending the service life of the guide structure. Furthermore, the four support frames at the bottom of the mold provide stable support on the vibrating equipment, preventing mold displacement and wobbling during vibration molding, ensuring uniform force on the blank, and improving density. The rollers between the coaxial support frames are compatible with workshop tracks, enabling flexible and stable transfer of the mold between different process equipment. This reduces manpower consumption for handling, improves production flow efficiency, and avoids station positioning deviations caused by movement jams or offsets, ensuring the accuracy of each process connection and indirectly improving the quality of the blank forming.

[0027] IV. Optimize power transmission adaptability, ensure vibration control, and improve production stability. The friction frame, mounted downwards at the bottom of the mold, precisely engages with the drive wheel of the vibration equipment, ensuring a smooth and efficient transmission of power from the vibration equipment to the mold. This guarantees stable and uniform vibration force during the vibration molding process, promoting the complete removal of air bubbles from the blank and increasing its density, thereby further optimizing the molding quality. This structure can be adapted to different models of vibration equipment without the need for additional adjustment components, enhancing the versatility of the mold and production line equipment, reducing equipment adaptation costs. Simultaneously, the reliable power transmission reduces production failures caused by power imbalances, improving the stability and continuity of the overall production process.

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] See Figure 1 When the autoclaved aerated concrete (AAC) billet mold is in operation, the side plate 2, which supports the billet, is first placed over the side opening of the mold body 1, which has openings at the top and sides. Then, by operating the pressing frame 3, which can move back and forth and is installed at the bottom of the mold body 1, the pressing frame 3 is moved towards the side plate 2 and securely fastened to the side opening of the mold body 1, ensuring that the side plate 2 will not loosen or shift when the concrete billet is poured in. Then, the concrete billet is poured into the mold body 1. After the billet is formed, the inner wall of the mold body 1 is covered with a demolding sealant. The coating layer significantly reduces the adhesion between the billet and the inner wall of the mold, allowing the formed billet to be easily removed from the mold body 1 with just a gentle operation. The clamping frame 3 securely fastens the side plate 2, effectively preventing problems such as grout leakage and missing corners during the pouring and billet forming process, thus ensuring the quality of the billet forming. The release coating layer makes the demolding process smoother, reducing billet damage and also reducing wear on the inner wall of the mold body 1, extending the service life of the mold. The overall operation is convenient and efficient, and can better meet the production needs of autoclaved aerated concrete billets.

[0033] See Figure 2 and Figure 3 When it is necessary to adjust the clamping frame 3 to achieve the fastening or loosening of the side plate 2, the screw 4, which is movably installed in the bottom space of the mold body 1 with the aid of bearings, can be rotated. Since the inner bottom of the clamping frame 3 is equipped with a bushing 5 that cooperates with the end of the screw 4, the rotation of the screw 4 will drive the bushing 5 to move synchronously, thereby driving the clamping frame 3 to move smoothly back and forth. This adjusts the clamping force of the clamping frame 3 on the side plate 2 or enables the disassembly of the side plate 2. Through the cooperation and transmission of the screw 4 and the bushing 5, the movement trajectory and position of the clamping frame 3 can be precisely controlled to ensure that the clamping force on the side plate 2 is uniform and stable, avoiding the side plate 2 from loosening or shifting during the blank forming process. At the same time, compared with manually pushing the clamping frame 3 directly, the operation is more labor-saving and convenient, and it can also reduce the jamming phenomenon when the clamping frame 3 moves, improving the overall operating efficiency and stability of the mold.

[0034] See Figure 4 and Figure 5 During mold adjustment and fixing operations, the other end of the lead screw 4 is movably mounted on the vertical plate of the mold body 1 with the aid of a bearing, providing support for the stable rotation of the lead screw 4. After rotating the lead screw 4 to adjust the position of the clamping frame 3 to ensure that the side plate 2 is securely fastened, since the tail end of the lead screw 4 passes through the vertical plate of the mold body 1 and is fixed with an outwardly expanding guide sleeve 6, and the guide sleeve 6 is provided with an integrally formed long strip-shaped limiting plate 7, the corresponding locking head can be engaged with the limiting plate 7 to lock together. Using other locking power heads, the lead screw can be driven. 4. Rotation: The lead screw 4 and guide sleeve 6 work together to move the clamping frame 3, thereby clamping the side plate 2. The lead screw 4 is mounted on the vertical plate of the mold body 1 through bearings, which ensures that its rotation is smooth and without deviation, providing a reliable basis for the precise adjustment of the clamping frame 3. The design of the guide sleeve 6 and the locking head in conjunction with the limiting plate 7 can effectively prevent the lead screw 4 from rotating on its own due to vibration and other factors during mold operation, thereby avoiding the positional deviation of the clamping frame 3 from affecting the clamping effect of the side plate 2, ensuring the overall working state of the mold is stable, and guaranteeing the forming quality of the blank.

[0035] See Figure 2 and Figure 3During the process of adjusting the clamping frame 3 to fasten or loosen the side plate 2, since the bottom of the mold body 1 is fixed with a central through-hole limiting sleeve 8, and the lower end of the clamping frame 3 is provided with a sliding rod 9 that can be inserted into the limiting sleeve 8, the sliding rod 9 will always slide synchronously inside the limiting sleeve 8 with the movement of the clamping frame 3. The limiting sleeve 8 will constrain the movement direction of the sliding rod 9. The advantage of this working method is that, through the cooperation of the limiting sleeve 8 and the sliding rod 9, it can effectively prevent the clamping frame 3 from deviating, shaking or jamming when moving back and forth, ensuring that the clamping frame 3 always runs smoothly along the preset trajectory, thereby ensuring that its fastening position on the side plate 2 is accurate and the force is uniform, preventing the side plate 2 from being not firmly fixed due to the displacement of the clamping frame 3 and causing leakage of slurry, improving the overall structural stability and working reliability of the mold, and also reducing the misalignment and wear between parts during the movement of the clamping frame 3, extending the service life of related parts.

[0036] See Figure 3 During the process of the clamping frame 3 driving the slide rod 9 to move along the limiting sleeve 8 to adjust the snap-fit ​​state of the side plate 2, the guide wheels 10, which are movably installed on the upper and lower sides of the limiting sleeve 8 through shafts and contact the side wall of the slide rod 9, will drive the guide wheels 10 to roll synchronously when the slide rod 9 moves. The guide wheels 10 always keep in close contact with the side wall of the slide rod 9. The guide wheels 10 can convert the sliding friction between the slide rod 9 and the limiting sleeve 8 into rolling friction, which greatly reduces the resistance when the slide rod 9 moves, making the adjustment operation of the clamping frame 3 smoother and less laborious, avoiding the adjustment jamming due to excessive friction. At the same time, it can also reduce the wear of the slide rod 9 and the limiting sleeve 8, extend the service life of both, and the close support of the guide wheels 10 on the slide rod 9 can further limit the swaying of the slide rod 9 in the limiting sleeve 8, ensure the precise movement trajectory of the clamping frame 3, ensure the accuracy of the snap-fit ​​position of the side plate 2, and improve the overall working stability of the mold.

[0037] See Figure 2 In the vibration molding process of autoclaved aerated concrete (AAC) billets, the mold needs to be placed on a vibration device. At this time, the four support frames 11 fixed at the bottom of the mold body 1 will directly contact the vibration device, stably supporting the entire mold at the designated position of the vibration device. During the process of the vibration device starting and driving the mold to vibrate to achieve billet compaction, the support frames 11 always maintain stable support for the mold. The four support frames 11 can provide balanced and reliable support force for the mold body 1, preventing the mold from tilting, shifting or shaking during vibration, ensuring that the concrete billet inside the mold is subjected to uniform force, thereby improving the compaction and molding quality of the billet. At the same time, the support frames 11 can also reduce the direct contact area between the bottom of the mold body 1 and the vibration device, reduce the wear of the bottom of the mold during vibration, and extend the service life of the mold body 1. In addition, the stable support state can also reduce the additional noise generated by the mold vibration and improve the production environment.

[0038] See Figure 2In the production process of autoclaved aerated concrete (AAC) billets, when the mold needs to be transferred between different process equipment in the workshop, the support frames 11 on the same axis are connected by rollers 12 that can cooperate with the workshop tracks. Simply push or use traction equipment to move the mold, and the rollers 12 will roll along the pre-laid tracks in the workshop, thus moving the entire mold smoothly to the target work position. The cooperation between the rollers 12 and the tracks makes the mold move more smoothly, avoiding the problems of mold deviation and jamming in traditional handling methods, greatly reducing the intensity of manual handling, and improving the transfer efficiency between processes. At the same time, the coaxial support frame 11 provides a stable installation base for the rollers 12, ensuring that the mold remains stable during the rolling of the rollers 12, preventing the unformed billets in the mold from spilling or forming deviations due to shaking. In addition, the rolling friction of the rollers 12 can also reduce the wear between the mold and the ground, extend the service life of the mold and the workshop floor, and ensure the continuity and stability of the production process.

[0039] See Figure 2 and Figure 4 In the vibration compaction process of autoclaved aerated concrete (AAC) billets, when the mold is placed on the vibration equipment, the friction frame 13, which is fixed at the bottom and installed downwards, precisely engages with the drive wheel on the vibration equipment. After the vibration equipment is started, the drive wheel rotates and transmits power through the friction between it and the friction frame 13, causing the friction frame 13 to act synchronously. This ensures that the entire mold body 1 receives a stable vibration force, guaranteeing that the concrete billet inside the mold can be fully compacted under the vibration force. The cooperation between the friction frame 13 and the drive wheel of the vibration equipment can efficiently transmit the vibration force, avoiding slippage or power loss during power transmission. This allows the mold to receive a uniform and sufficient vibration force, effectively improving the compaction of the billet, reducing air bubbles inside the billet, and ensuring molding quality. At the same time, power transmission can be achieved without the need for additional complex power connection structures, simplifying the cooperation process between the mold and the vibration equipment and enhancing the flexibility of their adaptation. In addition, stable power transmission can also prevent mold displacement or damage due to uneven vibration force, extending the service life of the mold and ensuring the stable operation of the production process.
