Description

Technical Field

[0001] This invention belongs to the field of reinforced concrete assembly mold technology, and more specifically, it relates to a rapid assembly mold for precast reinforced concrete components. Background Technology

[0002] Precast reinforced concrete component assembly molds belong to the category of cyclic concrete molding tools in the prefabricated building industry. They differ from fixed steel molds that are welded as a whole. The overall design adopts a modular disassembly, consisting of multiple independent mold modules, a load-bearing base, and matching locking components. During construction, different mold modules can be quickly aligned and assembled. The relative positions between the modules are fixed by the locking structure, forming a casting cavity that matches the shape of precast beams, columns, irregular wall panels, and other reinforced concrete components. Workers pour concrete slurry into the cavity, and after the slurry solidifies, the locking structure between the modules is released to complete the demolding. The entire mold can be repeatedly disassembled and reused, adapting to the processing needs of various specifications of precast components. It eliminates the need for on-site welding and mold repair, thereby shortening the preparation time for mold assembly.

[0003] The Chinese patent publication number is CN120465688A, which discloses a modular steel column external concrete mold. This invention breaks with the original approach. After the templates are initially enclosed on the outside of the steel column, the relative positions of the templates can be conveniently and efficiently locked and fixed synchronously through a positioning device, ensuring the production progress of the steel column external concrete composite structure.

[0004] Existing reinforced concrete casting molds have the following disadvantages: 1. In construction scenarios with low temperatures and frost in winter, after the traditional precast reinforced concrete component quick assembly mold completes the assembly operation, it relies solely on the gravity of the concrete slurry to complete the cavity filling operation. The low temperature environment will significantly reduce the flow performance of the concrete slurry. For mold cavities with complex structures and many bends, narrow gaps and dead corners, the autonomous flow range of the slurry is limited, making it difficult to cover the entire cavity area. This can easily lead to local filling gaps in the cavity and irregular component forming, affecting the forming quality and structural integrity of the precast components.

[0005] Second, traditional rapid assembly molds of the same type lack low-temperature adaptive heating and low-frequency vibration linkage structures. For winter low-temperature pouring conditions, they mostly rely on manual auxiliary heating or manual vibration. The rhythm and force of manual operation are difficult to control and cannot match the working rhythm of mold pouring. At the same time, continuous heating can easily cause local temperature abnormalities in the mold, affecting the curing performance of concrete. In addition, conventional high-frequency vibration can easily cause the mold assembly structure to loosen and leak grout, making it less suitable for low-temperature complex cavity construction.

[0006] In view of this, we will study and improve the existing structure and its shortcomings, and provide a quick assembly mold for precast reinforced concrete components in order to achieve a practical purpose. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a rapid assembly mold for precast reinforced concrete components.

[0008] A rapid assembly mold for precast reinforced concrete components includes an assembly base. The assembly base is equipped with an adjustment mechanism to facilitate uniform concrete pouring. The adjustment mechanism includes a drive shaft, guide rails, a connecting crossbar, a first assembly mold, and a second assembly mold. Each drive shaft is rotatably mounted on both sides of the assembly base. Both guide rails are located at the upper end of the assembly base. The connecting crossbar is fixedly installed between the two guide rails. Both the first and second assembly molds are fixedly installed at the upper ends of the two guide rails. An clearance groove is formed at the upper end of the assembly base. A pressure sensor is fixedly installed on the inner wall of the clearance groove. Two rubber base plates are fixedly installed at the upper end of the assembly base, and cushioning airbags are fixedly installed at the upper ends of both rubber base plates. The positions of the rubber base plate and the buffer airbag correspond to the guide rail crossbeams. An arc-shaped protrusion is fixedly installed at the circumferential end of each drive shaft. A low-speed motor is provided at the side end of one of the drive shafts. The low-speed motor is fixedly installed at the side end of the assembly base. The output end of the drive shaft on one side is fixedly installed. The same synchronous belt is sleeved between every two drive shafts. Two side blocks are fixedly installed at the side ends of the two guide rail crossbeams. An arc-shaped slider is fixedly installed at the side end of each side block. Each arc-shaped slider is in contact with each arc-shaped protrusion. A disc spring is fixedly installed between the two guide rail crossbeams and the assembly base. A rubber pressure plate is provided at the lower end of the connecting crossbeam. A telescopic rod and a spring are fixedly installed between the connecting crossbeam and the rubber pressure plate.

[0009] Preferably, the telescopic rod is located on the inner wall of the spring, and the rubber pressure plate and the pressure sensor are in contact.

[0010] Preferably, the upper ends of the first assembly mold and the second assembly mold are both provided with heating chambers, the inner sidewalls of the two heating chambers are fixedly installed with control bases, the upper ends of the two control bases are fixedly installed with electric heating rods, and the two ends of the second assembly mold are provided with locking sealing plates.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a low-speed motor, a drive shaft, an arc-shaped protrusion, and an arc-shaped slider are used in conjunction. The low-speed motor provides stable power output, driving the drive shaft and synchronous belt for synchronous transmission. The intermittent engagement and disengagement of the arc-shaped protrusion and the arc-shaped slider create a stable low-frequency reciprocating vibration state for the guide rail frame and the upper mold. In winter low-temperature and frost-prone construction scenarios, the rheological properties of concrete slurry decrease and the flow rate slows down due to the low temperature. Complex cavities have multiple bends, narrow grooves, and dead corners, making it difficult to achieve uniform filling with conventional self-weight pouring. This structure uses low-frequency continuous vibration to drive the viscous slurry inside the cavity to slowly slide and spread, gradually spreading and filling the gaps and dead corners of the cavity. This adapts to the molding requirements of complex cavities, improves the problem of insufficient filling and molding defects in the cavity under low-temperature conditions, and enhances the uniformity of concrete pouring and filling.

[0012] In this invention, a multi-layered flexible buffer support structure is formed by combining disc springs, rubber base plates, and buffer airbags during the reciprocating vibration operation of the mold. The continuous up-and-down reciprocating motion of the mold generates periodic mechanical impact force. The multi-layered buffer structure can absorb and weaken the rigid impact load generated during the vibration process step by step, reduce the hard friction and collision loss between the various assembly structures, extend the service life of the equipment, and at the same time, constrain the vibration amplitude and running trajectory of the guide rail frame, maintain the stability of the overall vibration process of the mold, weaken the local shaking and displacement of the mold, and make the vibration energy evenly transmitted to the entire mold cavity, so that the overall stress state of the concrete slurry is more balanced, which is conducive to improving the flatness of the overall casting.

[0013] In this invention, a guide rail frame, a first assembly mold, and a second assembly mold are provided to mount the first and second assembly molds on the upper end of the guide rail frame. The guide rail frame vibrates up and down, synchronously driving the two sets of assembly molds to start and stop simultaneously with synchronized amplitude vibration. This ensures that the vibration frequency and amplitude of the two sets of molds are highly uniform, preventing vibration rhythm deviations and inconsistent vibration states during the pouring process. It also reduces problems such as loosening of mold joints and misalignment caused by vibration misalignment, stabilizes the overall sealing of the mold assembly, reduces the probability of grout leakage and cavity deformation during vibration pouring, and ensures the overall consistency of complex cavity concrete pouring.

[0014] In this invention, a pressure sensor, a rubber pressure plate, and an electric heating rod are used in conjunction to adaptively match the intermittent start and stop of the electric heating rod by relying on the periodic pressure changes generated by the reciprocating motion of the mold vibration. This forms an intermittent auxiliary heating mode that is linked to the vibration operation. For low-temperature and frost conditions in winter, it can appropriately increase the ambient temperature of the mold cavity and the concrete slurry inside, and improve the problems of high viscosity, high flow resistance, and fast early setting speed of the slurry at low temperatures. Combined with low-frequency vibration to assist the flow and filling of the slurry, the intermittent heating method can reduce the continuous accumulation of heat, alleviate the abnormal local temperature rise of the mold, maintain the stability of the concrete slurry curing process, avoid the molding defects caused by abnormal temperature, and adapt to the continuous pouring operation requirements of complex cavities in low-temperature winter.

[0015] In this invention, a telescopic rod and a spring are used to flexibly buffer and adjust the pressure stroke during the process of the connecting crossbar driving the rubber pressure plate to press down and reset. This allows the pressure value acting on the pressure sensor to show a gradual increase and decrease, avoiding fluctuations and deviations in the detection data caused by instantaneous impact pressure. This effectively improves the stability and accuracy of the real-time detection data of the pressure sensor, ensures precise matching between the start-stop control logic of the electric heating rod and the vibration pouring rhythm of the mold, and enables the heating-assisted operation to adapt to the low-temperature rheological requirements of different filling stages of the slurry, stabilize the flow properties of the concrete slurry, and further optimize the filling effect of complex cavities.

[0018] The embodiments of the present invention will be described in further detail below 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 the invention.

[0019] Please see Figure 1 - Figure 8 This invention provides a rapid assembly mold for precast reinforced concrete components, including an assembly base 1. The assembly base 1 is equipped with an adjustment mechanism to facilitate uniform concrete pouring. The adjustment mechanism includes a drive shaft 2, guide rails 3, connecting crossbars 4, a first assembly mold 5, and a second assembly mold 6. Each drive shaft 2 is rotatably mounted on both sides of the assembly base 1. The two guide rails 3 are located at the upper ends of the assembly base 1. The connecting crossbars 4 are fixedly installed between the two guide rails 3. The first assembly mold 5 and the second assembly mold 6 are both fixedly installed at the upper ends of the two guide rails 3. Mold assembly and initial pouring operations can be performed first. The adjustment mechanism of this device mainly consists of the drive shaft 2, guide rails 3, connecting crossbars 4, first assembly mold 5, and second assembly mold 6. A hydraulic drive structure is mounted on the guide rails 3. During actual construction, workers can use the hydraulic drive structure configured on the guide rails 3 to drive the two sets of guide rails 3 to perform relative translational movement. The first assembly mold 5 and the second assembly mold 6, which are installed on the upper end of the guide rail frame 3, move synchronously to achieve precise alignment and assembly of the two sets of molds. After the first assembly mold 5 and the second assembly mold 6 are fully assembled, the locking and sealing plates 61 set on both sides of the second assembly mold 6 are used to lock, limit and seal the assembled first assembly mold 5 and the second assembly mold 6, effectively ensuring the integrity and sealing of the two sets of molds after assembly, and stably enclosing the complete component casting cavity. After the overall assembly and locking of the mold is completed, the workers pour precast reinforced concrete slurry into the mold cavity through the pre-reserved pouring holes at the top of the first assembly mold 5 and the second assembly mold 6, completing the initial mold assembly and initial concrete pouring operation, and providing basic conditions for subsequent auxiliary molding operations. The overall assembly process relies on the translational guiding effect of the guide rail frame 3, and the assembly alignment accuracy is high. With the help of the locking and sealing plates 61, the gap between the mold joints can be reduced, reducing the possibility of slurry leakage during the pouring process. An clearance groove 11 is provided at the upper end of the assembly base 1. A pressure sensor 12 is fixedly installed on the inner side wall of the clearance groove 11. Two rubber base plates 13 are fixedly installed at the upper end of the assembly base 1. A buffer airbag 14 is fixedly installed at the upper end of each of the two rubber base plates 13. The positions of the rubber base plates 13 and the buffer airbags 14 correspond to the guide rail crossbar 3. An arc-shaped protrusion 21 is fixedly installed at the circumferential end of each drive shaft 2. A low-speed motor 23 is provided at the side end of one drive shaft 2. The low-speed motor 23 is fixedly installed at the side end of the assembly base 1. The output end of the drive shaft 2 on one side is fixedly installed. The same synchronous belt 22 is sleeved between every two drive shafts 2. In the construction scenario of low temperature and frost in winter, the ambient temperature is low, and the concrete... The rheological properties of the slurry are affected by the environment, resulting in a decrease in fluidity. Furthermore, the cavity structure formed by the first assembly mold 5 and the second assembly mold 6 is complex, with numerous dead corners, narrow gaps, and bending areas. Relying solely on the gravity flow of the concrete slurry itself is insufficient to fully fill all areas within the cavity, easily leading to incomplete cavity filling and defects in the formed components. Therefore, the low-speed vibration structure of the device can be activated to assist in the pouring operation. Specifically, during operation, the low-speed motor 23, fixedly installed at the side end of the assembly base 1, is activated. The output end of the low-speed motor 23 drives the drive shaft 2 on one side to rotate. Simultaneously, the two sets of drive shafts 2 are fitted with the same synchronous belt 22, enabling synchronous and unidirectional rotation of the two drive shafts 2, ensuring uniform power transmission. Each drive shaft 2 has an arc-shaped protrusion 21 fixedly installed at its circumferential end. During the rotation of the drive shaft 2, the arc-shaped protrusion 21 continuously rotates in a circular motion. Two side blocks 31 are fixedly installed on the side ends of each of the two guide rail crossbars 3. An arc-shaped slider 32 is fixedly installed on the side end of each side block 31. Each arc-shaped slider 32 is in contact with each arc-shaped protrusion 21. Disc springs 33 are fixedly installed between the two guide rail crossbars 3 and the assembly base 1. When the convex surface of the arc-shaped protrusion 21 rotates to the upper position and contacts the bottom of the arc-shaped slider 32, it can push the arc-shaped slider 32 and the side block 31 upward. The side block 31 is fixed to the side end of the guide rail crossbar 3, thereby driving the entire guide rail crossbar 3. The mold moves smoothly upwards, simultaneously pushing the first assembly mold 5 and the second assembly mold 6, which are installed above the guide rail crossbeam 3, upwards. When the convex surface of the arc-shaped protrusion 21 continues to rotate and disengages from the bottom support position of the arc-shaped slider 32, the arc-shaped slider 32 loses its pushing force. The first assembly mold 5, the second assembly mold 6, and the guide rail crossbeam 3 automatically fall under their own gravity, thus forming a stable up-and-down reciprocating low-frequency vibration effect. During the reciprocating vibration of the molds, the disc spring 33 fixedly installed between the assembly base 1 and the guide rail crossbeam 3, and the upper end of the assembly base 1... The fixed rubber base plate 13 and the buffer airbag 14 above it work together to provide cushioning and stability. The disc spring 33 provides elastic support during the lifting and lowering of the guide rail crossbeam 3, balancing the impact force generated by the mold lifting and lowering, buffering the rigid vibration of the vertical reciprocating motion, and maintaining the stability of the guide rail crossbeam 3. The rubber base plate 13, as the basic buffer carrier, absorbs the vibration energy transmitted to the assembly base 1 during vibration, reducing rigid friction and impact between structures and reducing structural wear. The buffer airbag 14 is positioned corresponding to the guide rail crossbeam 3 and can be adjusted according to… The vibration amplitude adapts to deformation, further weakening the vibration impact. At the same time, it forms a flexible support for the guide rail frame 3, avoiding the displacement and swaying of the mold during reciprocating vibration. This device is driven by a low-speed motor 23 with a low vibration frequency, which can avoid the problem of concrete aggregate stratification and segregation caused by high-frequency vibration. Through continuous low-frequency reciprocating vibration, the low-temperature viscous concrete slurry inside the cavity flows slowly, gradually filling the dead corners and narrow gaps inside the cavity, improving the problem of insufficient self-flow of slurry under low-temperature conditions, and improving the uniformity of cavity filling. A rubber pressure plate 43 is provided at the lower end of the connecting crossbar 4. A telescopic rod 41 and a spring 42 are fixedly installed between the connecting crossbar 4 and the rubber pressure plate 43. The telescopic rod 41 is located on the inner side wall of the spring 42. The rubber pressure plate 43 is in contact with the pressure sensor 12. Heating chambers 51 are provided through the upper ends of the first assembly mold 5 and the second assembly mold 6. Control bases 53 are fixedly installed on the inner side walls of the two heating chambers 51. Electric heating rods 52 are fixedly installed on the upper ends of the two control bases 53. Locking sealing plates 61 are provided on both sides of the second assembly mold 6. The guide rail crossbar 3 rotates with the arc-shaped protrusion 21 to achieve up and down movement. During the reciprocating movement, the connecting crossbar 4 fixed between the two sets of guide rail crossbars 3 will move up and down synchronously. A telescopic rod 41 and a spring 42 are assembled between the connecting crossbar 4 and the bottom rubber pressure plate 43, and the telescopic rod 41 is nested inside the spring 42 to ensure the coaxial stability of the telescopic movement. When the guide rail crossbar 3 drives the connecting crossbar 4 to move downward, it will push the rubber pressure plate 43 to press down gradually. The rubber pressure plate 43 is in contact with the pressure sensor 12 installed inside the clearance groove 11 of the assembly base 1. During the pressing process, the spring 42 and the telescopic rod 41 cooperate to achieve flexible buffering, allowing the rubber pressure plate 43 to withstand the pressure. The downward pressure of sensor 12 gradually increases to avoid deviations in pressure detection data caused by instantaneous pressure shocks. When the pressure value detected by pressure sensor 12 exceeds the system's preset threshold, it sends an electrical signal to control base 53. Upon receiving the signal, control base 53 activates the electric heating rod 52 inside heating chamber 51. After the electric heating rod 52 starts working, it uniformly heats the cavity areas of the first assembly mold 5 and the second assembly mold 6, appropriately increasing the temperature of the mold cavity and the internal concrete slurry. This improves the problem of poor fluidity and fast curing speed of concrete slurry in low-temperature winter environments, and helps the slurry better fill complex cavities. When the arc-shaped protrusion 21 rotates and disengages from the arc-shaped slider 32, and the guide rail crossbar 3 drives the connecting crossbar 4 to rise upward, the rubber pressure plate 43 gradually moves away from the pressure sensor 12. The pressure value detected by the pressure sensor 12 continues to decrease. When the pressure value is lower than the preset threshold, the control base 53 promptly shuts off the electric heating rod 52 and stops the heating operation. Through the reciprocating motion characteristics of low-speed vibration, the pressure is periodically raised and lowered, thereby controlling the electric heating rod 52 to start and stop intermittently and work reciprocally. This avoids the electric heating rod 52 from working continuously for a long time, which would cause the temperature inside the mold to accumulate and rise, and reduce the situation where the concrete slurry undergoes performance changes due to excessive temperature.

[0020] Working principle: This device relies on the adjustment mechanism mounted on the assembly base 1 to realize the integrated operation of rapid mold assembly, low-temperature assisted vibration casting, and pressure-linked intermittent heating. It is suitable for construction scenarios with low temperature and frost in winter and complex cavities. The overall operation process is divided into three consecutive steps: assembly casting, vibration-assisted casting, and pressure-linked reciprocating heating. Each structure cooperates with each other to complete the casting and molding of precast concrete components.

[0021] The first step involves mold assembly and initial pouring. The adjustment mechanism of this device mainly consists of a drive shaft 2, a guide rail frame 3, a connecting crossbar 4, a first assembly mold 5, and a second assembly mold 6. The guide rail frame 3 is equipped with a hydraulic drive structure. During actual construction, workers can use the hydraulic drive structure on the guide rail frame 3 to drive the two sets of guide rail frames 3 to move relative to each other. This drives the first assembly mold 5 and the second assembly mold 6, which are installed on the upper end of the guide rail frame 3, to move synchronously, achieving precise alignment and assembly of the two sets of molds. After the first assembly mold 5 and the second assembly mold 6 are fully assembled, locking sealing plates 61 are installed on both sides of the second assembly mold 6. The first and second assembly molds 5 and 6 are locked, limited, and sealed to ensure the integrity and sealing of the two sets of molds after assembly, stably enclosing a complete component casting cavity. After the overall assembly and locking of the molds is completed, the workers pour precast reinforced concrete slurry into the mold cavity through the pre-reserved pouring holes at the top of the first and second assembly molds 5 and 6, completing the initial mold assembly and initial concrete pouring operations, providing the basic conditions for subsequent auxiliary molding operations. The overall assembly process relies on the translational guiding effect of the guide rail crossbeam 3, and the assembly alignment accuracy is high. With the help of the locking sealing plate 61, the gap between the mold joints can be reduced, reducing the possibility of slurry leakage during the pouring process.

[0022] The second step involves construction in low-temperature, frost-prone winter conditions. The low ambient temperature affects the rheological properties of the concrete slurry, reducing its fluidity. Furthermore, the cavity structure formed by the first and second assembly molds 5 is complex, containing numerous dead angles, narrow gaps, and bending areas. Relying solely on the gravity flow of the concrete slurry is insufficient to fully fill all areas within the cavity, leading to incomplete filling and defects in the formed components. Therefore, the low-speed vibration structure of the device can be activated to assist in the pouring process. Specifically, the low-speed motor 23, fixedly installed on the side of the assembly base 1, is activated. The output of the low-speed motor 23 drives the transmission shaft 2 on one side to rotate. Simultaneously, a synchronous belt 22 is fitted between the two sets of transmission shafts 2, enabling synchronous and unidirectional rotation of both transmission shafts 2 and ensuring uniform power transmission. Each drive shaft 2 has an arc-shaped protrusion 21 fixedly installed at its circumferential end. During the rotation of the drive shaft 2, the arc-shaped protrusion 21 will continuously rotate in a circular motion. When the convex surface of the arc-shaped protrusion 21 rotates to the upper position and comes into contact with the bottom of the arc-shaped slider 32, it can push the arc-shaped slider 32 and the side block 31 upward. The side block 31 is fixed to the side end of the guide rail cross frame 3, thereby driving the guide rail cross frame 3 to move upward smoothly as a whole, and simultaneously pushing the first assembly mold 5 and the second assembly mold 6 installed on the guide rail cross frame 3. The upward movement occurs when the convex surface of the arc-shaped protrusion 21 continues to rotate and disengages from the bottom support position of the arc-shaped slider 32. The arc-shaped slider 32 then loses its pushing force, and the first assembly mold 5, the second assembly mold 6, and the guide rail crossbeam 3 automatically fall under their own gravity, thus creating a stable up-and-down reciprocating low-frequency vibration effect. During the reciprocating vibration of the molds, the disc spring 33 fixedly installed between the assembly base 1 and the guide rail crossbeam 3, the rubber base plate 13 fixed to the upper end of the assembly base 1, and the buffer airbag 1 above the rubber base plate 13 all contribute to the vibration. 4. The device plays a synergistic role in buffering and stabilizing. The disc spring 33 provides elastic support during the lifting and lowering of the guide rail frame 3, balances the impact force generated by the lifting and lowering of the mold, buffers the rigid vibration of the vertical reciprocating motion, and maintains the stability of the guide rail frame 3. The rubber base plate 13 serves as the basic buffer carrier, which can absorb the vibration energy transmitted to the assembly base 1 during the vibration process, reduce the rigid friction and impact between structures, and reduce structural wear. The buffer airbag 14 is positioned corresponding to the guide rail frame 3 and can adapt to the deformation according to the vibration amplitude, further weakening the vibration impact. At the same time, it forms a flexible support for the guide rail frame 3, avoiding the situation of displacement and shaking during the reciprocating vibration of the mold. This device is driven by a low-speed motor 23 with a low vibration frequency, which can avoid the problem of concrete aggregate stratification and segregation caused by high-frequency vibration. Through continuous low-frequency reciprocating vibration, the low-temperature viscous concrete slurry inside the cavity flows slowly, gradually filling the dead corners and narrow gaps inside the cavity, improving the problem of insufficient self-flow of slurry under low-temperature conditions, and improving the uniformity of cavity filling. This application utilizes a combination of a low-speed motor 23, a drive shaft 2, an arc-shaped protrusion 21, and an arc-shaped slider 32. The low-speed motor 23 provides stable power output, driving the drive shaft 2 and synchronous belt 22. The intermittent engagement and disengagement of the arc-shaped protrusion 21 and the arc-shaped slider 32 create a stable low-frequency reciprocating vibration state for the guide rail frame 3 and the upper mold. In winter, under low-temperature and frost-prone construction conditions, the rheological properties of concrete slurry decrease and its flow rate slows due to low temperatures. Complex cavities often have multiple bends, narrow grooves, and dead corners, making uniform filling difficult with conventional self-weight pouring. This structure, through continuous low-frequency vibration, allows the viscous slurry inside the cavity to slowly slide and spread, gradually filling gaps and dead corners throughout the cavity. This adapts to the molding requirements of complex cavities, improves the problem of insufficient filling and molding defects in low-temperature conditions, and enhances the uniformity of concrete pouring. This application sets up a disc spring 33, a rubber base plate 13, and a buffer airbag 14 to form a multi-layer flexible buffer support structure during the reciprocating vibration operation of the mold. The mold continuously moves up and down, generating periodic mechanical impact force. The multi-layer buffer structure can absorb and weaken the rigid impact load generated during the vibration process step by step, reduce the hard friction and collision loss between the assembly structures, extend the service life of the equipment, and at the same time, it can constrain the vibration amplitude and running trajectory of the guide rail frame 3, maintain the stability of the overall vibration process of the mold, weaken the local shaking and displacement of the mold, and make the vibration energy evenly transmitted to the entire mold cavity, so that the overall stress state of the concrete slurry is more balanced, which is conducive to improving the flatness of the overall casting. This application sets up a guide rail frame 3, a first assembly mold 5, and a second assembly mold 6 to cooperate, thereby mounting the first assembly mold 5 and the second assembly mold 6 on the upper end of the guide rail frame 3. Relying on the overall up-and-down reciprocating vibration of the guide rail frame 3, the two sets of assembly molds are synchronously driven to start and stop synchronously and vibrate synchronously, so that the vibration frequency and vibration amplitude of the two sets of molds are kept highly uniform. This avoids the vibration rhythm deviation and inconsistent vibration state of the two independent molds during the pouring vibration process, reduces the problem of mold joint loosening and misalignment caused by vibration misalignment, stabilizes the overall assembly and sealing of the mold, reduces the probability of joint leakage and cavity deformation during vibration pouring, and ensures the overall consistency of complex cavity concrete pouring.

[0023] Thirdly, as the guide rail crossbeam 3 moves up and down in tandem with the arc-shaped protrusion 21, the connecting crossbar 4 fixed between the two sets of guide rail crossbeams 3 moves up and down synchronously. A telescopic rod 41 and a spring 42 are fitted between the connecting crossbar 4 and the bottom rubber pressure plate 43. The telescopic rod 41 is nested inside the spring 42 to ensure coaxial stability of the telescopic movement. When the guide rail crossbeam 3 moves the connecting crossbar 4 downwards, it pushes the rubber pressure plate 43 down gradually. The rubber pressure plate 43 fits against the pressure sensor 12 installed inside the clearance groove 11 of the assembly base 1. During the downward pressure, the spring 42 and the telescopic rod 41 work together to provide flexible buffering, allowing the downward pressure of the rubber pressure plate 43 on the pressure sensor 12 to gradually increase, avoiding instantaneous pressure shocks that could cause deviations in the pressure detection data. When the pressure value detected by the pressure sensor 12 exceeds the system's preset threshold, it sends an electrical signal to the control base 53. After receiving the signal, the control base 53... The electric heating rod 52 inside the heating chamber 51 is activated. After the electric heating rod 52 starts working, it uniformly heats the cavity areas of the first assembly mold 5 and the second assembly mold 6, appropriately increasing the temperature of the mold cavity and the internal concrete slurry. This improves the problem of poor fluidity and fast curing speed of the concrete slurry in low-temperature winter conditions, and helps the slurry to better fill the complex cavity. When the arc-shaped protrusion 21 rotates and disengages from the arc-shaped slider 32, the guide rail crossbar 3 drives the connecting crossbar 4 to rise upward. The rubber pressure plate 43 gradually moves away from the pressure sensor 12, and the pressure value detected by the pressure sensor 12 continues to decrease. When the pressure value is lower than the preset threshold, the control base 53 promptly shuts off the electric heating rod 52 and stops the heating operation. Through the reciprocating motion characteristics of low-speed vibration, the pressure is periodically raised and lowered, thereby controlling the electric heating rod 52 to start and stop intermittently and work reciprocally. This avoids the electric heating rod 52 working continuously for a long time, which would cause the internal temperature of the mold to accumulate and rise, and reduce the situation where the concrete slurry undergoes performance changes due to excessive temperature. Meanwhile, relying on the buffering effect of spring 42 throughout the process, the application and release of pressure are in a smooth state, ensuring the stability and continuity of the data detected by pressure sensor 12, making the control logic of heating start and stop more precise, realizing the synchronous coordination of vibration-assisted pouring and adaptive intermittent heating, and fully adapting to the complex cavity pouring construction scenario of low temperature and frost in winter. This application utilizes a pressure sensor 12, a rubber pressure plate 43, and an electric heating rod 52 to adapt to the periodic pressure changes generated by the reciprocating motion of the mold vibration. This allows for the intermittent start and stop of the electric heating rod 52, which is controlled in conjunction with the vibration operation, forming an intermittent auxiliary heating mode. For low-temperature and frost conditions in winter, this mode can appropriately increase the ambient temperature of the mold cavity and the internal concrete slurry, improving the problems of high slurry viscosity, high flow resistance, and rapid early setting speed at low temperatures. Combined with low-frequency vibration to assist slurry flow and filling, the intermittent heating method can reduce the continuous accumulation of heat, alleviate the abnormal local temperature rise of the mold, maintain the stability of the concrete slurry curing process, avoid molding defects caused by abnormal temperature, and adapt to the continuous pouring operation requirements of complex cavities in low-temperature winter conditions. This application utilizes a telescopic rod 41 and a spring 42 to flexibly buffer and adjust the pressure stroke during the pressing and resetting process of the rubber pressure plate 43 driven by the connecting crossbar 4. This ensures that the pressure value acting on the pressure sensor 12 exhibits a gradual increase and decrease, avoiding fluctuations in detection data caused by instantaneous impact pressure. This effectively improves the stability and accuracy of the real-time detection data from the pressure sensor 12, ensuring precise matching between the start / stop control logic of the electric heating rod 52 and the vibration pouring rhythm of the mold. This allows the heating-assisted operation to adapt to the low-temperature rheological requirements of different filling stages of the slurry, stabilizing the flow properties of the concrete slurry and further optimizing the filling effect of complex cavities.
