Description

Technical Field

[0001] This application relates to the field of molded fiberglass grating production technology, and in particular to a mold operation system for an automated production line of molded fiberglass grating. Background Technology

[0002] Molded fiberglass grating, with its excellent properties such as corrosion resistance, high strength, light weight, and easy installation, is widely used in many fields such as power, municipal engineering, sewage treatment, and marine engineering. With the rapid development of downstream industries, the market demand for molded fiberglass grating continues to grow, while simultaneously placing higher demands on its production efficiency, product quality stability, and production safety.

[0003] Currently, molds are required for the production of fiberglass grating. Existing molds include a template with several intermediate modules arranged in an array. The gaps between the intermediate modules, together with the template surface, form a grating-shaped molding groove. During production, resin is poured into the molding groove and filled with glass fiber. After the resin cures, the finished fiberglass grating is formed. However, the above-mentioned molds are only suitable for manual production and cannot meet the needs of continuous casting of fiberglass grating. Summary of the Invention

[0004] In order to meet the production needs of continuous casting of fiberglass grating and improve production efficiency, this application provides an automated production line mold operation system for molded fiberglass grating.

[0005] The mold operation system for the automated production line of molded fiberglass grating provided in this application adopts the following technical solution: An automated production line mold operation system for molded fiberglass grating includes molds and a frame. The frame has parallel running and return tracks. Several molds are continuously arranged on the running tracks, forming a molded body. A pushing mechanism is located at one end of each running track, pushing the molds into the running track and propelling the molded body along it. A demolding machine is located at the other end of the running track, separating the molds from the ends of the molded body and sending them to the return track. A lifting mechanism is located at the end of the return track away from the demolding machine. A transport mechanism is located on the return track, transporting the molds from the return track to the lifting mechanism. The lifting mechanism receives the molds transported by the transport mechanism and delivers them to the pushing mechanism.

[0006] By adopting the above technical solution, the mold-pushing mechanism pushes the mold into the running track. As subsequent molds are continuously fed in, several molds are arranged continuously on the running track to form a molded body. Because the mold-pushing mechanism continuously delivers molds into the running track, the subsequently entering molds are incorporated into the molded body, propelling it along the running track. During this process, production steps such as resin casting and fiberglass filling can be completed. When the mold on the molded body reaches the other end of the running track, the demolding machine peels the mold at the end of the molded body from the molded body and the finished fiberglass grating, and sends the empty mold to the return track. After the mold enters the return track, the transport mechanism conveys the mold on the return track to the mold-lifting mechanism. The mold-lifting mechanism receives the mold and transports it back to the mold-pushing mechanism, thus completing the entire mold cycle. This ensures the continuity of molded fiberglass grating production, meets the production requirements of continuous casting of fiberglass grating, and improves production efficiency.

[0007] Preferably, the lifting mechanism includes a lifting platform, a lifting screw, and a drive assembly. The lifting platform is slidably connected to the frame and can be aligned with the running track or the return track. The lifting screw is rotatably connected to the frame and threadedly connected to the lifting platform. The drive assembly is used to drive the lifting screw to rotate.

[0008] By adopting the above technical solution, before the conveying mechanism transports the mold on the return track to the mold lifting mechanism, the lifting platform is first aligned with the return track to facilitate the mold entering the lifting platform; then, the drive component drives the lifting screw to rotate, and the rotation of the lifting screw is converted into the movement of the lifting platform, so that the lifting platform is aligned with the running track, thereby transporting the mold to the mold pushing mechanism, realizing the transfer of the mold between the return track and the running track.

[0009] Preferably, two lifting screws are arranged parallel to each other on both sides of the frame. The drive assembly includes a rotating shaft, a commutator, and a first motor. The rotating shaft is rotatably connected to the frame and perpendicular to the axis of the lifting screws. The rotating shaft is connected to the two lifting screws via the commutator. The first motor is used to drive the rotating shaft to rotate.

[0010] By adopting the above technical solution, the two lifting screws arranged in parallel on both sides of the frame can support and drive the lifting platform from both sides, improving the stability of the lifting platform operation. In addition, the first motor drives the rotating shaft to rotate, and the rotating shaft transmits power to the two lifting screws through the commutator, so that the two lifting screws rotate synchronously, ensuring that the speed of the lifting screws on both sides is consistent, thereby ensuring that the lifting speed on both sides of the lifting platform is the same.

[0011] Preferably, the conveying mechanism includes several continuously arranged conveyor chain assemblies. Each conveyor chain assembly includes a drive sprocket, a driven sprocket, a transmission chain, and a second motor. The drive sprocket and the driven sprocket are spaced apart along the length of the return track. Both the drive sprocket and the driven sprocket are rotatably connected to the frame. The second motor is used to drive the drive sprocket to rotate. The transmission chain is arranged between the drive sprocket and the driven sprocket and is used to transport the mold closer to the mold lifting mechanism.

[0012] By adopting the above technical solution, when the second motor drives the active sprocket to rotate, the active sprocket drives the transmission chain to rotate, and the transmission chain then drives the driven sprocket to rotate synchronously. The mold is placed on the transmission chain and is transported as the transmission chain rotates. Moreover, several continuously arranged conveyor chain components can cover the length of the return track, shorten the distance between the active sprocket and the driven sprocket in the same group, and improve the load-bearing and conveying capacity.

[0013] Preferably, push ears are fixedly provided on both sides of the mold.

[0014] By adopting the above technical solution, the pusher provides a force point for the mold to be pushed, enabling each mechanism to stably apply force to the mold.

[0015] Preferably, the conveying mechanism includes a main mold return frame, a push cylinder, a secondary mold return frame, and an abutment. The main mold return frame is fixedly connected to the machine frame, and the secondary mold return frame is slidably connected to the main mold return frame in a direction parallel to the return track. The push cylinder is used to drive the secondary mold return frame to slide back and forth. The abutment is provided on the secondary mold return frame, and the abutment can abut against the side of the push lug near the demolding machine and push the mold from the return track into the mold lifting mechanism.

[0016] By adopting the above technical solution, when it is necessary to send the mold on the return track into the mold lifting mechanism, the push cylinder drives the return mold sub-frame to slide along the return mold main frame. The abutting part on the return mold sub-frame abuts against the push ears on both sides of the mold near the demolding machine. As the return mold sub-frame continues to slide, the abutting part pushes the mold to move, so that the mold can smoothly enter the mold lifting mechanism from the return track.

[0017] Preferably, the abutting member includes a torsion block and a relief wheel. The torsion block is rotatably connected to the mold return sub-frame, and the relief wheel is rotatably connected to the torsion block. The push lug is located on the side away from the demolding machine and can abut against the relief wheel, thereby driving the torsion block to rotate.

[0018] By adopting the above technical solution, when the mold moves towards the lifting mechanism on the return track, and the pusher is away from the demolding machine and abuts against the relief wheel, the pusher will drive the torsion block to rotate, which will drive the relief wheel to rotate and avoid the pusher, thus preventing the abutment from obstructing the normal movement of the mold.

[0019] Preferably, the mold ejection mechanism includes a slide block, a drive ejector block, and a power assembly. The slide block is slidably connected to the frame along the traveling direction of the molding body. The power assembly is used to drive the slide block to slide back and forth. The drive ejector block is rotatably connected to the slide block. The drive ejector block can abut against the side of the ejector lug away from the demolding machine and push the mold into the running track. The ejector lug can abut against the drive ejector block on the side of the ejector lug close to the demolding machine and drive the drive ejector block to rotate.

[0020] By adopting the above technical solution, the power unit drives the slide to slide along the frame. The drive push block on the slide abuts against the side of the mold's push lug away from the demolding machine. As the slide moves, the drive push block pushes the mold into the running track. When the power unit drives the slide to slide back to its original position, the side of the push lug closest to the demolding machine abuts against the drive push block, causing the drive push block to rotate and pass over the push lug.

[0021] Preferably, the power assembly includes a lead screw and a drive motor. The lead screw is rotatably connected to the frame and threadedly engaged with a slide block. The drive motor is used to drive the lead screw to rotate.

[0022] By adopting the above technical solution, the propulsion motor drives the propulsion screw to rotate. Since the propulsion screw is threadedly engaged with the slide and the slide is slidably connected to the frame, the rotation of the propulsion screw is converted into the linear sliding of the slide, thereby providing power for the movement of the slide.

[0023] Preferably, the mold pushing mechanism is provided in two sets on the frame, and the two sets of mold pushing mechanisms alternately push the mold along the running track.

[0024] By adopting the above technical solution, the two sets of mold pushing mechanisms work alternately. When one set of mold pushing mechanisms pushes the mold a certain distance and then resets, the other set of mold pushing mechanisms continues to push the mold forward, reducing the waiting time of the lifting platform on the running track.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up molds, frames, running and returning tracks, mold pushing mechanisms, demolding machines, mold lifting mechanisms, and conveying mechanisms, the molds are continuously arranged on the running track to form the molded body for continuous production. The demolded molds are then circulated back to the mold pushing mechanism via the returning track, mold lifting mechanism, and conveying mechanism, thus completing the cyclic operation of the molds to meet the production requirements of continuous casting of FRP gratings. 2. By setting up an active sprocket, a driven sprocket, a transmission chain, a second motor, a push lug, a return mold main frame, a push cylinder, a return mold sub-frame, a torsion block, and a clearance wheel, the mold is transported on the return track to the lifting platform. At the same time, the torsion block and clearance wheel are used to push the mold from the return track to the lifting platform. 3. By setting up a slide block, drive push block, push screw, and push motor, power is provided for the mold to enter the running track and to push the molding body forward, ensuring that the mold can enter the running track accurately and orderly and push the molding body forward continuously.

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0035] This application discloses a mold operation system for an automated production line of molded fiberglass grating. (Refer to...) Figure 1 It includes a mold 1 and a frame 2. Inside the frame 2, there are parallel running tracks 21 and return tracks 22 fixed along its own length direction. The running track 21 is located above the return track 22, and there is a gap between the running track 21 and the return track 22.

[0036] Reference Figure 1 Several molds 1 are arranged continuously on the running track 21, forming a molding body together. A mold pushing mechanism 3 is provided at one end of the running track 21, which pushes the molds 1 into the running track 21 and propels the molding body along the running track 21. A demolding machine 6 is provided at the other end of the running track 21, which peels the molds 1 from the end of the molding body and sends them to the return track 22. A mold lifting mechanism 4 is provided at the end of the return track 22 away from the demolding machine 6. A conveying mechanism 5 is provided on the return track 22, which transports the molds 1 on the return track 22 to the mold lifting mechanism 4. The mold lifting mechanism 4 receives the molds 1 transported by the conveying mechanism 5 and transports them to the mold pushing mechanism 3.

[0037] Reference Figure 2 The mold 1 includes a template 12, on which a plurality of intermediate modules 13 are arranged in an array. The gaps between the intermediate modules 13 and the surface of the template 12 together form a crisscrossing grid-like molding groove 14. Side plates 15 extending upwards are provided on both sides of the template 12 in the width direction of the frame. Sealing strips 16 are fixed and embedded on the end walls of the side plates 15 and the template 12 at both ends in the length direction of the frame 2. In the molding body, the sealing strips 16 on adjacent side plates 15 and the end walls of the template 12 fit together and abut against each other, preventing gel from leaking from the gaps between adjacent templates 12.

[0038] Reference Figure 2 The bottom of the template 12 is provided with a top plate 17. The top of the top plate 17 is fixed and vertically provided with a number of ejector pins 171. The ejector pins 171 penetrate the template 12 and slide to connect with the template 12. The upper surface of the ejector pins 171 is flush with the bottom wall surface of the forming groove 14.

[0039] Reference Figure 2 and Figure 3 Two guide rails 18 are fixedly installed at the bottom of the template 12. The guide rails 18 are parallel to the length direction of the frame 2 and have an I-shaped cross section. Push ears 11 are fixedly installed on both sides of the mold 1. The push ears 11 provide force points for the mold 1 to be pushed laterally.

[0040] Reference Figure 3 A number of rollers 211 are evenly and rotatably arranged on the running track 21 along the length direction. The axis of the rollers 211 is parallel to the width direction of the frame 2. The rollers 211 are used to support the mold 1 to reduce the friction between the mold 1 and the running track 21.

[0041] To facilitate the detachment of mold 1 from the end of the molding body and its placement into the return track 22, refer to... Figure 6 The demolding machine 6 includes a translation rail 61 fixedly connected to the frame 2. The translation rail 61 is parallel to the length direction of the frame 2. A demolding trolley 62 is mounted on the translation rail 61 and slides along the length direction of the frame 2 connected to the translation rail 61. A third power component 63 is mounted on the translation rail 61 to drive the demolding trolley 62 to slide. The third power component 63 is a cylinder fixedly mounted on both sides of the translation rail 61, and the output end of the third power component 63 is fixedly connected to the demolding trolley 62.

[0042] Reference Figure 6 A demolding platform 64 is slidably mounted on the demolding carriage 62 along the height direction of the frame 2. The demolding carriage 62 is equipped with a first power component 65 for driving the demolding platform 64 to slide. The first power component 65 is a cylinder fixedly mounted on both sides of the demolding carriage 62, and the output end of the first power component 65 is fixedly connected to the demolding platform 64.

[0043] Reference Figure 6 and Figure 7 Two sleeve rails 66 are fixedly installed on the demolding platform 64, and the sleeve rails 66 are parallel to the length direction of the frame 2. The sleeve rails 66 have grooves that are adapted to the guide rails 18, and the guide rails 18 can extend into the grooves on the sleeve rails 66 along the length direction of the frame 2. Side pressing parts 67 corresponding to the side plates 15 are fixedly installed on both sides of the demolding platform 64. The side pressing parts 67 have pressing grooves 671 on their adjacent side walls. The side plates 15 can extend into the pressing grooves 671 along the length direction of the frame 2, and the pressing grooves 671 can abut against the top of the side plates 15.

[0044] Reference Figure 6 and Figure 7 A push plate 681 is slidably disposed on the demolding platform 64 along the height direction of the frame 2. A second power component 68 is disposed on the demolding platform 64 to drive the push plate 681 to slide. The second power component 68 is a hydraulic cylinder fixedly disposed on the demolding platform 64. The output end of the hydraulic cylinder is fixedly connected to the push plate 681. The top of the push plate 681 can abut against the bottom of the top plate 17 and push the top plate 17 to slide upward.

[0045] Reference Figure 6 and Figure 7The demolding platform 64 is fixedly connected to an ejector cylinder 69. The output end of the ejector cylinder 69 slides along the length of the frame 2. The output end of the ejector cylinder 69 can abut against the template 12 and eject the mold 1 from the demolding platform 64.

[0046] Reference Figure 6 and Figure 7 When the molding body travels along the length of the frame 2 on the running track 21, the demolding trolley 62, driven by the third power component 63, moves to the front of the molding body's travel direction. The first power component 65 then drives the demolding platform 64 to rise, aligning the sleeve rail 66 with the guide rail 18 of the mold 1 to be docked in the height direction of the frame 2. Subsequently, the third power component 63 drives the demolding trolley 62 to slide in the opposite direction to the molding body's travel, causing the guide rail 18 and sleeve rail 66 to face each other. The guide rail 18 extends into the sleeve groove of the sleeve rail 66 along the mold 1's travel direction, completing a rapid docking. Simultaneously, the side plate 15 also extends into the pressure groove 671 of the side pressure part 67 along the mold 1's travel direction, achieving longitudinal positioning of both sides of the mold 1. Next, the second power component 68 drives the push plate 681 to slide upwards, which in turn pushes the top plate 17 upwards. The top plate 17 then drives the ejector pin 171 to move upwards simultaneously, ejecting the cured fiberglass grating from the molding groove 14. During this process, the first power component 65 drives the demolding platform 64 downwards, with the sleeve rail 66 and guide rail 18 in a docking state, and the tops of the pressure plates on both sides of the mold 1 being abutted by the pressure groove 671. The mold 1 moves downwards along with the demolding platform 64, and the downward speed of the demolding platform 64 is the same as the upward speed of the ejector pin 171, keeping the finished fiberglass grating stationary relative to the molding body and preventing the finished fiberglass grating from bending. Afterwards, the demolding platform 64 moves downwards to be flush with the return track 22, and the ejection cylinder 69 pushes the empty mold 1 out of the demolding platform 64, allowing the empty mold 1 to enter the return track 22. At this point, the demolding platform 64 is free, and it can continue to complete the demolding work for subsequent molds 1. The empty mold 1 is then conveyed by the conveying mechanism 5 and moves closer to the lifting mechanism 4.

[0047] To facilitate the return of the empty mold 1 conveyed by the demolding machine 6 to the mold pushing mechanism 3, refer to Figure 3 The lifting mechanism 4 includes a lifting platform 41, a lifting screw 42, and a drive assembly 43. The lifting platform 41 is slidably connected to the frame 2 along the height direction of the frame 2, and the lifting platform 41 can be aligned with the running track 21 or the return track 22. When the lifting platform 41 is aligned with the running track 21, the pushing mechanism 3 can push the mold 1 on the lifting platform 41 into the running track 21. When the lifting platform 41 is aligned with the return track 22, the conveying mechanism 5 can transport the mold 1 on the return track 22 into the lifting platform 41.

[0048] Reference Figure 3Two lifting screws 42 are arranged parallel to each other on both sides of the frame 2 in the width direction. The axis of the lifting screws 42 is parallel to the height direction of the frame 2 and is rotatably connected to the frame 2. The lifting screws 42 are threadedly connected to both sides of the lifting platform 41 in the width direction of the frame. The drive assembly 43 is used to drive the lifting screws 42 to rotate. Specifically, the drive assembly 43 includes a rotating shaft 431, a commutator 432, and a first motor 433. The rotating shaft 431 is parallel to the width direction of the frame 2 and is rotatably connected to the frame 2. The rotating shaft 431 is perpendicular to the axis of the lifting screws 42. The rotating shaft 431 is connected to the two lifting screws 42 through the commutator 432. The first motor 433 is fixedly connected to the frame 2. The output end of the first motor 433 is connected to the rotating shaft 431 to drive the rotating shaft 431 to rotate.

[0049] Reference Figure 4 A blocking platform 7 is slidably mounted on the frame 2 along its height direction. An upwardly extending baffle 71 is fixedly mounted on the blocking platform 7. The baffle 71 is located between the lifting platform 41 and the return track 22 along the length of the frame 2. A compressible push spring 72 is provided at the bottom of the blocking platform 7. One end of the push spring 72 is fixed to the bottom of the blocking platform 7, and the other end is fixed to the frame 2. When the push spring 72 is not compressed, the baffle 71 on the blocking platform 7 blocks the movement path of the mold 1 away from the return track 22.

[0050] Reference Figure 4 The bottom of the lifting platform 41 is fixedly provided with a downward pressure block 73. The bottom of the downward pressure block 73 can abut against the top of the blocking platform 7, so that the blocking platform 7 compresses the push spring 72 and moves down. When the lifting platform 41 is aligned with the return track 22, the downward pressure block 73 presses down on the blocking platform 7, so that the baffle 71 moves down to a path away from the mold 1 and away from the return track 22.

[0051] Reference Figure 1 , Figure 3 and Figure 4The conveying mechanism 5 includes a conveyor chain assembly 51, a return mold main frame 52, a push cylinder 53, a return mold sub-frame 54, and an abutment member 55. Several sets of conveyor chain assemblies 51 are continuously arranged along the length of the frame. Each set of conveyor chain assemblies 51 includes a drive sprocket 511, a driven sprocket 512, a transmission chain 513, and a second motor 514. The drive sprockets 511 and driven sprockets 512 are spaced apart along the length of the return track 22. Both drive sprockets 511 and driven sprockets 512 are rotatably connected to the frame 2, and their axes are parallel to the width direction of the frame 2. The second motor 514 is fixedly connected to the frame 2, and its drive shaft is coaxially connected to the drive sprockets 511, used to drive the drive sprockets 511 to rotate. A drive chain 513 is configured to drive between a driving sprocket 511 and a driven sprocket 512. One end of the drive chain 513 is fitted onto the driving sprocket 511, and the other end is fitted onto the driven sprocket 512. The top of the drive chain 513 is used to support the mold 1 and transport the mold 1 closer to the lifting mechanism 4. The drive chains 513 in the multiple conveyor chain assemblies 51 sequentially feed the mold 1, causing the mold 1 to move closer to the lifting platform 41.

[0052] Reference Figure 3 and Figure 4 The main mold return frame 52 is fixedly connected to the frame 2. The auxiliary mold return frame 54 is slidably connected to the main mold return frame 52 along a direction parallel to the return track 22. The push cylinder 53 is used to drive the auxiliary mold return frame 54 to slide back and forth. The abutment 55 is provided on the auxiliary mold return frame 54. The abutment 55 includes a torsion block 551 and a relief wheel 552. The torsion block 551 is rotatably connected to the auxiliary mold return frame 54, and the axis of the torsion block 551 is parallel to the width direction of the frame 2. The relief wheel 552 on the torsion block 551 can abut against the side of the push lug 11 near the demolding machine 6 and push the mold 1 from the return track 22 into the lifting mechanism 4. During this process, the auxiliary mold return frame 54 abuts against the torsion block 551, preventing the torsion block 551 from rotating. The relief wheel 552 is rotatably connected to the torsion block 551, and the axis of the relief wheel 552 is parallel to the width direction of the frame 2. The push lug 11 can abut against the relief wheel 552 on the side away from the demolding machine 6. At this time, the return mold sub-frame 54 does not obstruct the rotation of the torsion block 551. The push lug 11 drives the torsion block 551 to rotate, and the rotation of the torsion block 551 provides clearance space for the push lug 11 to pass.

[0053] In order to push the mold 1 on the lifting platform 41 into the running track 21, refer to Figure 5Two sets of push-die mechanisms 3 are provided on the frame 2. The two sets of push-die mechanisms 3 alternately push the mold 1 forward along the running track 21. The push-die mechanism 3 includes a slide 31, a drive push block 32, and a power assembly 33. In the same set of push-die mechanisms 3, two slides 31 are symmetrically arranged on both sides of the width direction of the frame 2. The slides 31 are slidably connected to the frame 2 along the traveling direction of the molding body (i.e., the length direction of the frame 2). The power assembly 33 is used to drive the slides 31 to slide back and forth. The drive push block 32 is rotatably connected to the slides 31. The axis of the drive push block 32 is perpendicular to the length direction of the frame 2. When the slide 31 moves towards the demolding machine 6, the drive push block 32 can abut against the side of the push lug 11 away from the demolding machine 6 and push the mold 1 into the running track 21. At this time, the slide 31 abuts against the drive push block 32, preventing the drive push block 32 from deflecting. Thus, when the new empty mold 1 enters the running track, it merges into the end of the molding body and pushes the front end of the molding body forward to enter the demolding machine 6 for demolding.

[0054] Reference Figure 5 When the slide block 31 moves away from the demolding machine 6, the push lug 11 can abut against the drive push block 32 on the side closer to the demolding machine 6. At this time, the slide block 31 does not obstruct the deflection of the push block, and the push lug 11 can drive the drive push block 32 to rotate. In addition, a return torsion spring is provided at the rotational connection between the slide block 31 and the drive push block 32. One end of the return torsion spring is fixed to the drive push block 32, and the other end is fixed to the slide block 31. The return torsion spring drives the drive push block 32 to abut against the slide block 31. The power assembly 33 includes a lead screw 331 and a drive motor 332. The lead screw 331 is rotatably connected to the frame 2. The axis of the lead screw 331 is parallel to the length direction of the frame 2. The lead screw 331 is threadedly engaged with the slide block 31. The drive motor 332 is fixedly connected to the frame 2. The drive shaft of the drive motor 332 is coaxially connected to the lead screw 331 and is used to drive the lead screw 331 to reciprocate.

[0055] The implementation principle of the mold running system of the automated production line for molded fiberglass grating in this embodiment is as follows: During system operation, the propulsion motor 332 drives the propulsion screw 331 to rotate reciprocally, causing the slide block 31 to slide reciprocally. When the slide block 31 moves towards the demolding machine 6, the drive push block 32 abuts against the side of the push ear 11 away from the demolding machine 6, and pushes the mold 1 on the lifting platform 41 into the running track 21. After the empty mold 1 pushed by the drive push block 32 enters the running track 21, it merges into the end of the molding body and pushes the front end of the molding body forward to enter the demolding machine 6 for demolding. During the movement of the molding body on the running track 21, empty molds 1 are continuously replenished at its end in the direction of movement, thus forming a continuous molding body. Continuous casting can be performed within the molding body to form a continuous finished fiberglass grating. When the slide block 31 moves away from the demolding machine 6, the push lug 11 can abut against the drive push block 32 on the side closer to the demolding machine 6. At this time, the slide block 31 does not obstruct the deflection of the drive push block 32, and the push lug 11 can drive the drive push block 32 to rotate.

[0056] As the molding body moves along the running track 21, the demolding trolley 62, driven by the third power component 63, moves to the front of the molding body in the direction of travel. The first power component 65 then drives the demolding platform 64 to rise, aligning the sleeve rail 66 with the guide rail 18 of the mold 1 at the front of the molding body in the height direction of the frame 2. Subsequently, the third power component 63 drives the demolding trolley 62 to slide in the opposite direction to the molding body's travel, causing the guide rail 18 and sleeve rail 66 to face each other. The guide rail 18 extends into the sleeve groove of the sleeve rail 66 along the mold 1's travel direction, completing a rapid connection. Simultaneously, the side plate 15 also extends into the pressure groove 671 of the side pressure part 67 along the mold 1's travel direction. Next, the second power component 68 drives the push plate 681 to slide upwards. The push plate 681 pushes the top plate 17 upwards, and the top plate 17 drives the ejector pin 171 to move upwards simultaneously, ejecting the cured fiberglass grating from the molding groove 14. During this process, the first power component 65 drives the demolding platform 64 to move downwards, the sleeve rail 66 and the guide rail 18 are in a docking state, and the tops of the pressure plates on both sides of the mold 1 are abutted by the pressure grooves 671. The mold 1 moves downwards with the demolding platform 64, and the downward speed of the demolding platform 64 is the same as the upward speed of the ejector pin 171, so that the finished fiberglass grating remains stationary relative to the molding body, avoiding bending of the finished fiberglass grating. Afterwards, the demolding platform 64 moves downwards to be flush with the return track 22, and the ejection cylinder 69 pushes the empty mold 1 out of the demolding platform 64, so that the empty mold 1 enters the return track 22. At this time, the demolding platform 64 is free, and the demolding platform 64 can continue to complete the demolding work of the subsequent mold 1. The empty mold 1 then moves closer to the lifting mechanism 4 under the conveying of the transport mechanism 5.

[0057] The empty mold 1 on the return track 22 is sequentially fed by the drive chain 513 in the multiple conveyor chain assemblies 51 and approaches the lifting platform 41. When the lifting platform 41 is higher than the return track 22, the push spring 72 is not compressed or is not fully compressed, and the baffle 71 on the blocking platform 7 moves upward to prevent the mold 1 from leaving the return track 22. When the lifting platform 41 moves down to be level with the return track 22, the downward pressure block 73 presses down on the blocking platform 7, causing the baffle 71 to move downward away from the path where the mold 1 leaves the return track 22. At this time, the mold 1 can leave the return track 22 and enter the lifting platform 41.

[0058] As the output end of the push cylinder 53 reciprocates, when the return mold support 54 moves away from the demolding machine 6, the clearance wheel 552 on the torsion block 551 abuts against the side of the push lug 11 closest to the demolding machine 6, pushing the mold 1 from the return track 22 into the lifting mechanism 4, thus providing assistance for pushing the mold 1 from the return track 22 into the lifting mechanism 4. During this process, the return mold support 54 abuts against the torsion block 551, hindering the rotation of the torsion block 551. When the return mold support 54 moves closer to the demolding machine 6, the push lug 11 abuts against the clearance wheel 552 on the side away from the demolding machine 6. At this time, the return mold support 54 does not hinder the rotation of the torsion block 551; the push lug 11 drives the torsion block 551 to rotate, and the torsion block 551 provides clearance space for the push lug 11 to pass through by rotating. After the push lug 11 passes the torsion block 551, the torsion block 551 resets under the action of gravity and abuts against the return mold support 54 again.

[0059] After mold 1 enters the lifting platform 41, the first motor 433 drives the two lifting screws 42 to rotate through the rotating shaft 431 and the commutator 432, thereby driving the lifting platform 41 to rise. When the lifting platform 41 rises to be level with the running track 21, the lifting platform 41 stops moving. The push motor 332 drives the push screw 331 to rotate, causing the slide 31 to move towards the demolding machine 6, driving the push block 32 to abut against the side of the push lug 11 of mold 1 on the lifting platform 41 away from the demolding machine 6, and pushing the empty mold 1 onto the running track 21, so that mold 1 is incorporated into the end of the molding body, thereby continuing to participate in the production process of fiberglass grating and completing the continuous cycle of mold 1.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
