Description

Technical Field

[0001] This invention relates to the field of precast component preparation technology, and in particular to an integrated device for opening and closing, cleaning and spraying of segment molds and its usage method. Background Technology

[0002] Currently, the pre-processing steps of precast component plant segment molds mainly involve traditional manual operations, segmented operations using single-machine equipment, and single-task operations using industrial robots. These methods generally suffer from fragmented processes and poor coordination: manual operations are inefficient and produce inconsistent quality; while automated single-machine equipment improves efficiency at individual points, the material flow and positioning between independent units (such as cleaning machines and spraying machines) result in slow overall cycle times, large footprints, and system complexity; and general-purpose robots are mostly used to complete single tasks, making it difficult to complete the entire process of mold opening and closing, cleaning, and spraying in a coherent and efficient manner on a single piece of equipment. This leads to low levels of automation and integration in the pre-processing steps, becoming a bottleneck restricting the intelligentization and efficiency improvement of the production line. Summary of the Invention

[0003] In view of this, the present invention provides an integrated device for opening and closing, cleaning and spraying of segment molds and its usage method. The present invention is used on the production line of a precast component factory and can automatically complete the processes of opening the segment mold, cleaning the mold cavity, spraying the release agent and finally closing the mold in sequence.

[0004] An integrated device for opening and closing, cleaning, and spraying of tunnel segment molds includes an overall frame, end mold opening and closing mechanisms at both ends of the overall frame, side mold opening and closing mechanisms on both sides of the overall frame, and a mold cleaning and spraying mechanism at the top of the overall frame. The end mold opening and closing mechanism includes an end mold pushing mechanism that is slidably mounted on the overall frame and can move in the height direction of the overall frame, and an end mold fastening mechanism that is fixed on the end mold pushing mechanism and can move in the width direction of the overall frame. The side mold opening and closing mechanism includes multiple side mold pushing mechanisms slidably mounted on the overall frame and multiple movable frames. Each movable frame is equipped with a side mold fastening mechanism that can move in the height direction of the overall frame. The multiple side mold fastening mechanisms are independently controlled. Both the end mold fastening mechanism and the side mold fastening mechanism are equipped with positioning elements to align them with the end mold bolts or the side mold bolts.

[0005] Preferably, the end mold pushing mechanism includes an end mold crossbeam, with both ends of the end mold crossbeam respectively clamped onto vertical slide rails fixed on the overall frame. A through hole is provided in the center of the end mold crossbeam, and an end mold drive shaft is arranged horizontally in the through hole. An end mold fastening mechanism is provided on the end mold drive shaft. An end mold lifting block is fixed on both sides of the end mold crossbeam at the through hole. An end mold pushing element is obliquely fixed on each end mold lifting block, and an end mold pushing plate is hinged to the piston rod end of each end mold pushing element.

[0006] Preferably, the end mold fastening mechanism and the side mold fastening mechanism have the same structure, both including a transmission support block, a fastening push element fixed on the transmission support block, a rotary motor fixed on the piston rod of the fastening push element, and a fastening rotating rod fixed on the output shaft of the rotary motor. The end of the fastening rotating rod has a groove for locking the bolt head of the end mold bolt or the side mold bolt, and the positioning element is fixed on the transmission support block.

[0007] Preferably, the positioning element is an industrial camera.

[0008] Preferably, the side mold pushing mechanism includes multiple side mold supporting blocks, each side mold supporting block is inclinedly fixed with a side mold pushing element, the piston rod end of each side mold pushing element is hingedly fixed with a side mold pushing plate, and each side mold supporting block is slidably arranged on a first transverse slide rail fixed to the lower part of the inner side of the overall frame.

[0009] Preferably, the movable frame includes a vertically arranged fixed frame and sliders fixed to the upper and lower ends of the fixed frame. The upper and lower sliders are slidably arranged on the upper and lower second transverse slide rails fixed to the inner side of the overall frame.

[0010] Preferably, the mold cleaning and spraying mechanism includes a horizontal transport block, which is movably mounted on a third transverse slide rail fixed to the top of the overall frame. Two horizontal slide rails and a second driving element are fixed to the bottom of the horizontal transport block. The second driving element is located between the two horizontal slide rails. A connecting block is slidably mounted on each of the two horizontal slide rails. A first driving element is fixed to the bottom of each of the two connecting blocks. A rotating cleaning device is fixed to the movable end of one of the first driving elements, and a dust suction device is fixed to the movable end of the other first driving element. A gas valve assembly is fixed to the movable end of the second driving element. Multiple cleaning nozzles and multiple spraying nozzles are connected to the gas valve assembly, and the cleaning nozzles and spraying nozzles are spaced apart.

[0011] Preferably, the rotary cleaning device includes a housing, a rotary motor, and a cleaning brush head. The rotary motor is disposed inside the housing, and its output shaft extends from the bottom of the housing to connect with the cleaning brush head located below the housing.

[0012] A method for using an integrated device for opening and closing, cleaning, and spraying of segment molds specifically includes the following steps: S1, before the segment mold flows from the production line to the integrated segment mold opening and closing, cleaning and spraying device, the end mold opening and closing mechanism, the side mold opening and closing mechanism and the mold cleaning and spraying mechanism are reset. At this time, the end mold opening and closing mechanism is located at the top of its slide rail. S2, the segment mold enters the interior of the overall frame. Then, the control makes the rotating cleaning device and the dust collection device of the mold cleaning and spraying mechanism descend and move left and right synchronously. During the process of the rotating cleaning device cleaning the end mold, side mold and bottom mold of the segment mold, the dust collection device performs negative pressure dust collection on the cleaned mold surface to complete the first round of cleaning. S3, after the first round of cleaning is completed, the rotating cleaning device is reset, the gas valve group is controlled to descend, and the cleaning nozzle is used to clean the segment mold in the second round. During the cleaning process, the dust collection device performs negative pressure dust collection on the cleaned mold surface. After the second round of cleaning, a fixed amount of release agent is evenly sprayed onto the segment mold using a spray nozzle. After the spraying is completed, the gas valve assembly, along with the spray nozzle and cleaning nozzle, is reset. S4, control the end mold opening and closing mechanism to descend, and control the end mold pushing mechanism to push the end mold so that the end mold and the bottom mold make precise contact. Then control the end mold fastening mechanism to move back and forth to align with the end mold bolts. Then control the end mold fastening mechanism to tighten the end mold bolts to lock the end mold and the bottom mold. After the end mold and the bottom mold are locked, control the end mold opening and closing mechanism to reset. The side mold opening and closing mechanism is controlled to push the side mold to make precise contact between the side mold and the bottom mold. Then, the side mold fastening mechanism is controlled to move up and down to align with the side mold bolts. Then, the side mold fastening mechanism is controlled to tighten the side mold bolts to lock the side mold and the bottom mold. After the side mold and the bottom mold are locked, the side mold opening and closing mechanism is controlled to reset. S5. After the segment mold is completed, it is moved out of the overall frame for segment construction. After the segment construction is completed, the segment mold is moved back into the overall frame for mold opening.

[0013] The beneficial effects of this invention are: 1. This invention achieves full automation and efficient assembly line operation of the pretreatment process, significantly improving production efficiency. This invention organically integrates the four major processes of mold opening, cleaning, spraying, and mold closing into a single piece of equipment. A mobile, integrated frame carries each functional unit, allowing the segment molds within the integrated equipment to perform sequential operations, completely eliminating the need for multiple transfers and repetitive positioning of the segment molds between different independent workstations. This design transforms the discontinuous operations scattered across multiple workstations in the traditional model into a continuous, automated, and compact process within a single piece of equipment, significantly shortening the pretreatment time of a single set of segment molds and substantially improving the overall cycle time and capacity of the production line.

[0014] 2. This invention ensures high quality, consistency, and reliability in pretreatment operations, laying the foundation for a superior appearance of the tunnel segments. By employing machine vision-guided precise loosening and tightening of bolts (controlling the number of turns and torque), zero-deviation opening and closing of the end and side molds is achieved, ensuring the dimensional accuracy of the molds. The cleaning process utilizes a three-stage collaborative cleaning mode of rotating wire brush, high-pressure air blowing, and negative pressure dust collection to thoroughly remove residue from the mold cavity. The spraying process uses intelligent nozzles with adjustable flow and atomization to ensure uniform, quantitative, and full coverage of the release agent coating. Centralized control throughout the entire process minimizes manual intervention, resulting in stable and repeatable work quality, directly improving the appearance quality of the subsequently cast tunnel segments.

[0015] 3. This invention enhances the flexibility and intelligence of the equipment, providing core support for building intelligent production lines. This equipment not only integrates a multi-degree-of-freedom adjustment mechanism to adapt to molds of different specifications, but its seamless connection and collaborative operation with the production line conveyor system itself demonstrates a high degree of system integration and flexibility. Furthermore, by integrating visual inspection, sensors, and data interaction interfaces, the equipment can monitor operational status and quality parameters in real time, enabling intelligent monitoring, data traceability, and adaptive optimization of the production process, thus powerfully promoting the digital and intelligent transformation and upgrading of precast component factories.

[0016] 4. This invention organically integrates the four core pre-processing steps of mold opening, cleaning, spraying, and mold closing into a continuous and automated process, eliminating the need for multiple transfers and repetitive positioning of the mold between independent workstations, significantly shortening the pre-processing cycle of a single mold, fundamentally improving overall work efficiency, and solving the problem of process fragmentation in the current segment mold opening and closing.

[0017] 5. This invention improves automation and consistency of work quality: Through an integrated mechanical structure and centralized control system, precise and automatic control of the entire process is achieved. This ensures the cleanliness of mold cleaning, the uniformity and completeness of mold release agent spraying, minimizes human interference, and guarantees the stability and repeatability of pretreatment process quality, thus laying the foundation for the subsequent production of segments with excellent appearance quality.

[0018] 6. This invention enhances the adaptability and intelligence of the equipment: enabling the integrated equipment to adapt to segment molds of different specifications and sizes within a certain range, and to monitor and provide feedback on key parameters such as mold status, cleaning effect, and coating amount, providing core equipment support for building a flexible and intelligent precast component production line.

[0032] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0033] The present invention provides an integrated device for opening and closing, cleaning and spraying of pipe segment molds, including an overall frame 1, end mold opening and closing mechanisms 3 disposed at both ends of the overall frame 1, side mold opening and closing mechanisms 4 disposed on both sides of the overall frame 1, and mold cleaning and spraying mechanism 5 disposed at the top of the overall frame 1.

[0034] Specifically, the overall frame 1 is a rectangular frame, which consists of a top rectangular frame, support columns vertically fixed at the four corners of the top rectangular frame, and two connecting rods connecting the left and right support columns. Vertical slide rails 1-1 are fixed on the opposite inner sides of the two left support columns, and first horizontal slide rails 1-2 are fixed on the opposite inner sides of the two connecting rods. Second horizontal slide rails 1-3 are fixed at the top of the two connecting rods and at corresponding positions on the lower surface of the top rectangular frame. A third horizontal slide rail 1-4 is fixed horizontally in the center of the top rectangular frame.

[0035] The end mold opening and closing mechanism 3 is located at the left and right ends of the overall frame 1. It includes an end mold pushing mechanism that is slidably mounted on the overall frame 1 and can move in the height direction of the overall frame 1, and an end mold fastening mechanism that is fixed on the end mold pushing mechanism and can move in the width direction of the overall frame 1. The end mold pushing mechanism is used to press the end mold against the bottom mold when the segment mold is closed, so that the end mold fastening mechanism can tighten the end mold bolts, or to press the end mold against the bottom mold when the segment mold is opened, so that the end mold fastening mechanism can loosen the end mold bolts.

[0036] The end mold pushing mechanism includes an end mold beam 3-1. The two ends of the end mold beam 3-1 are respectively locked onto the vertical slide rail 1-1 fixed on the overall frame 1. A through hole 3-2 is opened in the center of the end mold beam 3-1. An end mold drive shaft 3-3 is arranged horizontally in the through hole 3-2. The end mold fastening mechanism is set on the end mold drive shaft 3-3. An end mold lifting block 3-4 is fixed on both sides of the through hole 3-2 of the end mold beam 3-1. An end mold pushing element 3-5 is obliquely fixed on each end mold lifting block 3-4. An end mold pushing plate 3-6 is hinged to the piston rod end of each end mold pushing element 3-5.

[0037] The end mold beam 3-1 is connected by a power mechanism A (including a transmission mechanism and a drive motor, which can be a gear and rack transmission mechanism, not shown in the figure). Using the drive motor and the transmission mechanism, the end mold beam 3-1 can move up and down along the vertical slide rail 1-1, thereby moving the end mold pushing element 3-5 and the end mold fastening mechanism fixed on it synchronously to adjust its position in the vertical direction.

[0038] The end mold fastening mechanism includes a transmission support block 7, a fastening push element 10 fixed on the transmission support block 7, a rotary motor 8 fixed on the piston rod of the fastening push element 10, and a fastening rotating rod 9 fixed on the output shaft of the rotary motor 8. The end of the fastening rotating rod 9 has a groove for securing the bolt head of the end mold bolt. The transmission support block 7 is mounted on the end mold drive shaft 3-3, which is connected via a power mechanism B (including a transmission mechanism and a drive motor, not shown in the figure). A positioning element 2 is fixed on the transmission support block 7. The positioning element 2 is used to accurately position the fastening rotating rod 9 in the vertical direction, aligning it with the end mold bolt for subsequent tightening or loosening operations.

[0039] Since the end mold bolts on some end molds are inclined, i.e. at a certain angle to the horizontal plane, in order to ensure that the fastening rotating rod 9 can be aligned with the end mold bolts, in this case, one side of the fixing and fastening pushing element 10 of the transmission support block 7 can be set as an inclined surface to ensure that the fastening rotating rod 9 is in an inclined state. Alternatively, a wedge can be fixed on the transmission support block 7, and the fastening pushing element 10 can be fixed on the wedge to ensure that the fastening rotating rod 9 is in an inclined state, so that the inclination angle of the fastening rotating rod 9 is consistent with the inclination angle of the end mold bolt.

[0040] Power mechanism A drives the end mold crossbeam 3-1 to move up and down to the height position where the end mold bolt is located. Then, power mechanism B drives the end mold drive shaft 3-3 to rotate. When the end mold drive shaft 3-3 rotates, since the end mold drive shaft 3-3 is threadedly connected to the drive support block 7, the drive support block 7 can move forward and backward along the width direction of the overall frame 1 along the end mold drive shaft 3-3. When the drive support block 7 moves, the positioning element 2 positions the end mold bolt at all times. When the fastening rotating rod 9 is aligned with the end mold bolt, the drive support block 7 stops moving. Then, control the end mold pushing element 3-5 to make the end mold pushing plate 3-6 press against the end mold, so that the end mold and the bottom mold are in close contact. Then, control the fastening pushing element 10 to move it, along with the rotary motor 8 and the fastening rotating rod 9, toward the end mold, so that the groove at the end of the fastening rotating rod 9 engages with the bolt head of the end mold bolt. Then, control the start of the rotary motor 8 to make the rotary motor 8 rotate with the fastening rotating rod 9 to tighten or loosen the end mold bolt.

[0041] In this embodiment, the positioning element 2 is an industrial camera with machine vision recognition function. It can autonomously locate the position of the end mold bolt and transmit the position data of the end mold bolt to the controller, so that the controller can control the two power mechanisms of the end mold fastening mechanism, the fastening push element 10 and the rotary motor 8 to operate, thereby realizing the tightening or loosening of the end mold bolt.

[0042] The side mold opening and closing mechanism 4 is set on the front and rear sides of the overall frame 1. The side mold pushing mechanism is located inside the two connecting rods of the overall frame 1 and can move left and right along the length of the overall frame 1. The movable frame is located between the top rectangular frame of the overall frame 1 and the connecting rod and can also move left and right along the length of the overall frame 1. The side mold fastening mechanism is fixed in the movable frame and can move up and down in the movable frame.

[0043] The side mold opening and closing mechanism 4 includes multiple side mold pushing mechanisms and multiple movable frames slidably mounted on the overall frame 1. Each movable frame is equipped with a side mold fastening mechanism that can move in the height direction of the overall frame 1. The multiple side mold fastening mechanisms are independently controlled. The multiple side mold pushing mechanisms can be centrally controlled or independently controlled.

[0044] The side mold pushing mechanism includes multiple side mold lifting blocks 4-1, each of which is obliquely fixed with a side mold pushing element 4-2. Each side mold pushing element 4-2 has a side mold pushing plate 4-3 hinged to the piston rod end. Each side mold lifting block 4-1 is slidably mounted on a first transverse slide rail 1-2 fixed to the lower inner side of the overall frame 1. Multiple side mold lifting blocks 4-1 located on the same side can be connected to the same power mechanism C, which centrally and synchronously controls the multiple side mold lifting blocks 4-1. Alternatively, each side mold lifting block 4-1 on the same side can be equipped with its own power mechanism, allowing for independent control (similarly, the power mechanism used to control the movement of the side mold lifting blocks is not shown in the figure).

[0045] The movable frame includes a vertically arranged fixed frame 4-4 and sliders 4-5 fixed to the upper and lower ends of the fixed frame 4-4. The upper and lower sliders 4-5 are slidably mounted on upper and lower second transverse slide rails 1-3 fixed to the overall frame 1. A through hole is provided on the fixed frame 4-4, and a vertical slide rail is provided on the wall of the through hole. The side mold fastening mechanism is movably mounted on this vertical slide rail and can move up and down along it. The sliders 4-5 are connected to a power mechanism D (not shown in the diagram), which can drive the movable frame to move left and right along the length of the overall frame 1.

[0046] The structure of the side mold fastening mechanism is the same as that of the end mold fastening mechanism, and will not be described in detail here. The difference is that the transmission support block 7 of the side mold fastening mechanism is set on the vertical slide rail in the through hole of the fixed frame 4-4. The transmission support block 7 is also fixed with a positioning element 2, which is used to accurately position the fastening rotating rod 9 in the vertical direction so that the fastening rotating rod 9 is aligned with the side mold bolt for subsequent tightening or loosening operations. The transmission support block 7 of the side mold fastening mechanism is connected to the power mechanism E (not shown in the figure), and the power mechanism E can move the side mold fastening mechanism up and down.

[0047] The power mechanism C drives the side mold pushing mechanism to move left and right, so that the side mold pushing mechanism moves to one side of the side mold. At the same time, the power mechanism D moves the movable frame and the side mold fastening mechanism on it to move left and right, so that the side mold fastening mechanism moves to the position of the side mold bolt. Then, the power mechanism E drives the side mold fastening mechanism to move up and down. During the movement, the positioning element 2 positions the side mold bolt at all times. When the fastening rotating rod 9 of the side mold fastening mechanism is aligned with the side mold bolt, the side mold fastening mechanism stops moving. Then, control all the side mold pushing mechanisms' side mold pushing elements 4-2 to make all the side mold pushing plates 4-3 press against the side mold, making the side mold and bottom mold in close contact. Then, control all the side mold fastening mechanisms' fastening pushing elements 10 to move simultaneously, so that they move with their respective rotary motors 8 and fastening rotating rods 9 toward the side mold, so that the grooves at the ends of each fastening rotating rod 9 respectively engage with the bolt heads of their respective side mold bolts. Then, start each rotary motor 8 synchronously, so that each rotary motor 8 drives each fastening rotating rod 9 to rotate, to tighten or loosen each side mold bolt.

[0048] The mold cleaning and spraying mechanism 5 includes a horizontal transport block 5-1, which is movably mounted on the third transverse slide rail 1-4 fixed to the top of the overall frame 1. The horizontal transport block 5-1 is connected to the power mechanism F, which can slide the horizontal transport block 5-1 and all its components to the left and right.

[0049] Two horizontal slide rails 5-2 are fixed to the bottom of the horizontal transport block 5-1. A connecting block is slidably mounted on each of the two horizontal slide rails 5-2. A first driving element 5-3 is fixed to the bottom of each of the two connecting blocks. A rotary cleaning device 5-4 is fixed to the movable end of one of the first driving elements, and a vacuuming device 5-5 is fixed to the movable end of the other first driving element. The two connecting blocks are respectively connected to their respective power mechanisms G. The two power mechanisms G drive the rotary cleaning device 5-4 and the vacuuming device 5-5 fixed on the two connecting blocks to move back and forth.

[0050] The rotary cleaning device 5-4 is used to clean the end mold, side mold and bottom mold of the segment mold, and the dust collection device 5-5 performs negative pressure dust collection on the cleaned mold surface.

[0051] The rotary cleaning device 5-4 includes a housing, a rotary motor, and a cleaning brush head 5-10. The rotary motor is housed within the housing, and its output shaft extends from the bottom of the housing to connect with the cleaning brush head 5-10 located below the housing. In this embodiment, the cleaning brush head 5-10 is a wire brush head.

[0052] The vacuuming device 5-5 can be any vacuum cleaner that can achieve negative pressure vacuuming.

[0053] A second drive element 5-6 is fixed to the bottom of the horizontal transport block 5-1, located between two horizontal slide rails 5-2. A gas valve assembly 5-7 is fixed to the movable end of the second drive element 5-6. Multiple cleaning nozzles 5-8 and multiple coating nozzles 5-9 are connected to the gas valve assembly 5-7, spaced apart. The cleaning nozzles 5-8 perform secondary cleaning on the segment mold, while the coating nozzles 5-9 spray a measured amount of release agent into the inner cavity of the segment mold.

[0054] This invention also provides a method for using an integrated device for opening and closing, cleaning, and spraying of segment molds, specifically including the following steps: S1, the segment mold flows from the front line of the production line to the integrated segment mold opening and closing, cleaning and spraying device mentioned above, and resets the end mold opening and closing mechanism 3, the side mold opening and closing mechanism and the mold cleaning and spraying mechanism 5. At this time, the end mold opening and closing mechanism 3 is located at the top of its slide rail.

[0055] S2, the segment mold enters the interior of the overall frame. Then, the rotating cleaning device 5-4 and the dust collection device 5-5 of the mold cleaning and spraying mechanism 5 are controlled to descend and move left and right synchronously. During the process of the rotating cleaning device 5-4 cleaning the end mold, side mold and bottom mold of the segment mold, the dust collection device 5-5 performs negative pressure dust collection on the cleaned mold surface to complete the first round of cleaning.

[0056] That is, the two first driving elements 5-3 are controlled to move, driving the rotary cleaning device 5-4 and the dust collection device 5-5 to descend adaptively. Then, the power mechanism F and the two power mechanisms G are controlled to make the rotary cleaning device 5-4 and the dust collection device 5-5 move sequentially from left to right and from front to back along the third transverse slide rail 1-4 and the horizontal slide rail 5-2, respectively, to clean the end mold, side mold and bottom mold of the tube segment mold. During the cleaning process, the dust collection device 5-5 performs negative pressure dust collection on the cleaned mold surface to complete the first round of cleaning.

[0057] S3, after the first round of cleaning is completed, the rotating cleaning device 5-4 is reset, the second driving element 5-6 is controlled to make the gas valve group 5-7 adaptively descend, and the power mechanism F is controlled to make the cleaning nozzle 5-10 on the dust collection device 5-5 and the gas valve group 5-7 move from left to right. The cleaning nozzle 5-10 is used to perform the second round of cleaning on the tube mold. During the cleaning process, the dust collection device 5-5 performs negative pressure dust collection on the cleaned mold surface to complete the first round of cleaning. After the second round of cleaning, the dust collection device 5-5 is reset, and the power mechanism F is controlled to move the spray nozzle 5-9 on the gas valve group 5-7 from left to right. The spray nozzle 5-9 is used to evenly spray a certain amount of release agent onto the tube mold. After the release machine finishes spraying, the gas valve group 5-7 is used to reset the spray nozzle 5-9 and the cleaning nozzle 5-10.

[0058] S4, control the end mold opening and closing mechanism 3 to descend, and control its end mold pushing mechanism to push the end mold so that the end mold and the bottom mold make precise contact. Then control its end mold fastening mechanism to move back and forth to align with the end mold bolts. Then control the end mold fastening mechanism to tighten the end mold bolts to lock the end mold and the bottom mold. After the end mold and the bottom mold are locked, control the end mold opening and closing mechanism 3 to reset. The control mechanism of the side mold opening and closing mechanism 4 pushes the side mold to make precise contact between the side mold and the bottom mold. Then, the control mechanism of the side mold fastening mechanism moves up and down to align with the side mold bolts. Then, the control mechanism of the side mold fastening mechanism tightens the side mold bolts to lock the side mold and the bottom mold. After the side mold and the bottom mold are locked, the control mechanism of the side mold opening and closing mechanism 4 is reset.

[0059] S5. The segment mold that has been completed is moved out of the overall frame 1 for segment construction. After a series of segment construction procedures such as concrete pouring, steel reinforcement cage placement, embedded part installation, concealed works acceptance, water removal and finishing, and segment curing (steam curing), the segment mold is moved back into the overall frame 1 for mold opening.

[0060] The mold opening process is similar to the mold closing process. First, the end mold push plate 3-6 is pressed against the end mold. Then, the fastening rotating rod 9 is moved towards the end mold, so that the groove at the end of the fastening rotating rod 9 engages with the bolt head of the end mold bolt. Then, the rotary motor 8 is controlled to rotate the fastening rotating rod 9 in the opposite direction to loosen the end mold bolt. After the end mold bolt is completely loosened, the end mold push element 3-5 slowly resets the end mold push plate 3-6, and the end mold push plate 3-6 gradually disengages from the end mold. Finally, the entire end mold opening and closing mechanism 3 is reset.

[0061] Then, control the side mold push plate 4-3 to press against the side mold. Then, move the fastening rotating rod 9 of the side mold fastening mechanism toward the side mold, so that the groove at the end of the fastening rotating rod 9 engages with the bolt head of the side mold bolt. Then, control the rotary motor 8 to rotate the rotary motor 8 with the fastening rotating rod 9 in the opposite direction to loosen the side mold bolt. After the side mold bolt is completely loosened, the side mold push element 4-2 slowly resets with the side mold push plate 4-3, and the side mold push plate 4-3 gradually disengages from the side mold. Then, control the entire side mold opening and closing mechanism 4 to reset.

[0062] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
