Description

Technical Field

[0001] The invention relates to the technical field of aerated concrete block processing equipment, in particular to an aerated concrete block casting device. Background Art

[0002] Aerated concrete is a lightweight, porous building material that is commonly used in the construction industry due to its excellent thermal insulation properties, fire resistance and easy processing.

[0003] When processing aerated concrete blocks, siliceous materials and calcium materials are usually used to make slurry, and then the mixed slurry is poured into a pre-prepared mold. The slurry is left to stand in the mold for a period of time to initially solidify, and then the solidified body is demolded from the mold, and then the demolded body is autoclaved and cured. The autoclaved body is cut into the required blocks by special cutting equipment, and the processing is completed.

[0004] In the prior art, after the slurry of the aerated concrete block is injected into the mold, it is necessary to vibrate the slurry with a vibrating rod to remove bubbles generated in the slurry during the pouring process, making the slurry more compact and ensuring that the aerated concrete block obtained has higher quality.

[0005] For example, the patent with the authorization announcement number CN211440432U discloses an autoclaved aerated concrete block exhaust device, which includes a support frame, a motor is installed on the top of the support frame, the power output end of the motor is connected to the power input end of the rotating shaft, a rotating rod is welded to the bottom of the rotating shaft, columns are fixedly connected to both ends of the rotating rod, a horizontal plate is welded to the bottom of the column, a defoaming box is connected to the gap on the right side of the horizontal plate, the air inlet of the defoaming box extends to the inside of the nozzle through a feeding pipe, the feeding pipe is detachably connected to a material valve, and a vibrating rod is fixedly connected to the bottom of the horizontal plate, and there are multiple vibrating rods. When the device is in use, the concrete defoamer in the defoaming box is sprinkled into the concrete through the nozzle, and the vibrating rod rotates and stirs to evenly mix the defoamer and concrete, which can quickly eliminate bubbles in the concrete.

[0006] However, the vibrating rod in the device cannot be cleaned in time after use, and the concrete slurry is easy to solidify on the vibrating rod, which will cause many problems. The large amount of slurry from the previous batch remaining on the vibrating rod may be mixed into the next batch of slurry, causing the slurry composition to change and affecting the slurry quality. After the slurry solidifies, it will adhere to the outside of the vibrating rod for a long time, which will also cause the vibrating rod to be corroded and affect the quality of the vibrating rod. Summary of the invention

[0007] The invention provides an aerated concrete block casting device to solve the technical problem that after the vibrating rod in the aerated concrete block casting device in the prior art vibrates the concrete slurry, the concrete slurry attached to the outer side of the vibrating rod is difficult to be cleaned in time.

[0008] To solve the above problems, a casting device for aerated concrete blocks provided by the present invention adopts the following technical solutions:

[0009] A casting device for aerated concrete blocks includes a working support. A casting box with an open top is installed on the working support. Above the casting box, there is a grouting mechanism and a vibrating mechanism that can move up and down. The vibrating mechanism includes a mounting frame and multiple vibrating rods installed at the bottom of the mounting frame. The mounting frame is slidably installed on the working support up and down. Below the mounting frame, there is a scraping plate. The scraping plate is slidably sleeved outside the multiple vibrating rods up and down. An elastic member I is connected between the scraping plate and the mounting frame;

[0010] A sliding stop block is horizontally and elastically slidably installed on the working support. The sliding stop block is located above the casting box and is in upper and lower blocking with the scraping plate. The top of the sliding stop block is provided with a pushing inclined surface. During the process of the scraping plate moving downward with the mounting frame, the scraping plate can push the sliding stop block through the pushing inclined surface and cross over the sliding stop block. During the process of the scraping plate moving upward with the mounting frame, the scraping plate can be blocked by the sliding stop block and move away from the mounting frame;

[0011] The sliding stop block is in transmission connection with the mounting frame, so that the sliding stop block can be driven by the mounting frame to move away from the scraping plate after the bottom end of the vibrating rod is flush with the bottom surface of the scraping plate when the mounting frame moves upward, so that the scraping plate is separated from the sliding stop block and is driven by the elastic member I to move upward and reset.

[0012] Adopting the above technical solutions, a scraping plate is arranged below the mounting frame. When the mounting frame drives the vibrating rod to move downward and the vibrating rod is inserted into the casting box, the scraping plate descends together with the mounting frame. When the scraping plate moves downward, it can cross over the sliding stop block. After the vibrating rod finishes vibrating, when the mounting frame drives the vibrating rod to move upward, the scraping plate is blocked by the sliding stop block and no longer moves upward synchronously with the mounting frame. At this time, the scraping plate is getting farther and farther away from the mounting frame, while the vibrating rod moves upward synchronously with the mounting frame. During this process, the scraping plate scrapes the slurry adhering to the outer side wall of the vibrating rod. When the bottom end of the vibrating rod is flush with the bottom surface of the scraping plate, the slurry outside the vibrating rod is basically scraped off. At this time, when the mounting frame continues to move upward, it will drive the sliding stop block to move away from the scraping plate, so that the scraping plate is separated from the sliding stop block, and the scraping plate can move upward and reset under the action of the elastic member I.

[0013] By scraping the slurry adhering to the outside of the vibrating rod with the scraping plate, the cleaning method is simple and convenient, and the outer side wall of the vibrating rod can be cleaned in time, avoiding a series of adverse effects caused by the long-term adhesion of the slurry to the outside of the vibrating rod. The sliding stop block can trigger the relative movement between the scraping plate and the vibrating rod to clean the vibrating rod. By making the sliding stop block in transmission connection with the mounting frame, the sliding stop block can be separated from the scraping plate as the mounting frame moves upward after the cleaning is completed, so that the scraping plate is reset under the action of the elastic member I. By driving the sliding stop block to move through the mounting frame, the movement of the sliding stop block does not need to be driven separately, and the structure is simple and ingenious.

[0014] The present invention sets the scraper to be connected to the mounting frame through an elastic member 1 and can move up and down with the mounting frame. Compared with the scraper fixedly set above the casting box, if a jam occurs during the process of scraping the slurry, the elastic buffer of the elastic member 1 can reduce the impact load of the equipment and avoid hard impact on the scraper and the vibrating mechanism. At the same time, the scraper can move up and down with the mounting frame. After the vibration process is completed, the scraper, the vibrating rod and the mounting frame can be moved to the top of the casting box, leaving the space above the casting box, so as to directly trim the surface of the vibrated slurry at the vibration position, without having to move the casting box to the side of the scraper for trimming. The vibration and surface trimming can be performed at the same station, which can save production space.

[0015] Furthermore, an elastic member that can elastically expand and contract in the horizontal direction is connected between the sliding block and the working bracket, and a pull rod that can move horizontally is installed on the working bracket. The pull rod is located on the side of the sliding block that is away from the scraper in the horizontal direction. One end of the pull rod is inserted into the sliding block for sliding in the horizontal direction, and blocks each other with the sliding block in the relative sliding direction. The other end of the pull rod is transmission-connected to the mounting frame. After the mounting frame moves upward until the bottom end of the vibrating rod is flush with the bottom surface of the scraper, the pull rod is driven by the upwardly moving mounting frame to pull the sliding block back to the scraper to separate the sliding block from the scraper.

[0016] With the above technical solution, an elastic member 2 is connected between the sliding block and the working bracket, realizing the elastic sliding connection of the sliding block on the working bracket, the end of the pull rod is slidably inserted on the sliding block and blocks each other with the sliding block in the relative sliding direction, the end of the pull rod is slidably inserted on the sliding block, and the pull rod can slide relative to the sliding block, so that the sliding block has a stroke that does not drive the pull rod to move synchronously, and in the process of the scraper moving downward over the sliding block, the sliding block moves within this stroke without driving the pull rod to move, and does not affect the transmission state between the pull rod and the mounting frame. The pull rod and the sliding block block are blocked with each other in the relative sliding direction, so that the subsequent pull rod can drive the sliding block to move horizontally and separate the sliding block from the scraper.

[0017] Furthermore, one end of the pull rod facing away from the sliding stopper is connected with a rack, and a gear is rotatably installed on the working bracket. The gear and the rack are meshed with each other. A spiral sleeve is coaxially connected to the gear. A vertically extending transmission rod is also installed on the mounting frame. The transmission rod is inserted into the spiral sleeve and the inner ring of the gear. The transmission rod has a spiral matching section. After the mounting frame moves upward until the bottom end of the vibrating rod is flush with the bottom surface of the scraper, the spiral matching section is driven by the upward moving mounting frame to cooperate with the gear spiral transmission, thereby driving the gear to rotate, and the gear drives the rack to move back to the scraper, so as to drive the pull rod to pull the sliding stopper to move back to the scraper.

[0018] By adopting the above technical solution, the transmission connection between the mounting bracket and the pull rod is realized by setting gears, racks and transmission rods, and the structure is simple and easy to arrange.

[0019] Further, a vertically arranged cleaning plate is provided at the top of the inner cavity of the pouring box body. The top surface of the cleaning plate is attached to the bottom surface of the scraping plate blocked by the sliding block. The cleaning plate can move back and forth left and right in the pouring box body when the bottom end of the vibrating rod is flush with the bottom surface of the scraping plate, so as to scrape off the slurry attached to the bottom surface of the scraping plate.

[0020] By adopting the above technical solution, after the scraping plate scrapes off the slurry attached to the vibrating rod, a part of the slurry will adhere to the bottom surface of the scraping plate. By setting the cleaning plate, after the scraping plate scrapes off the slurry on the vibrating rod, the cleaning plate then scrapes off the slurry on the bottom surface of the scraping plate, avoiding the slurry attached to the bottom surface from being brought back to the vibrating rod when the scraping plate resets upward.

[0021] Further, the pouring box body includes a main box body with an open top end and front side, and a side plate that can be detachably installed on the front side of the main box body.

[0022] By adopting the above technical solution, the pouring box body includes a side plate and a main box body that are detachably connected together. After the slurry is initially cured in the pouring box body, the side plate and the main box body can be disassembled to facilitate demoulding.

[0023] Further, connecting plates II are connected to both the left and right sides of the main box body. Connecting holes II that penetrate through the front and back are provided on the connecting plates II. Connecting plates I are connected to both the left and right sides of the side plate. Connecting holes I that penetrate through the front and back and are opposite to the connecting holes II in the front and back direction are provided on the connecting plates I. There is a gap between the connecting plates I and the connecting plates II in the front and back direction. A connecting member is provided between the connecting plates I and the connecting plates II. The connecting member includes an elastic telescopic rod and stoppers I and II respectively connected to both ends of the elastic telescopic rod. The elastic telescopic rod is inserted into the corresponding connecting holes I and II. Under the action of the elastic telescopic rod, the stoppers I and II are respectively pressed against the outer sides of the connecting plates I and II. An installation chute I that communicates the connecting hole I with the outside is provided on the connecting plate I. An installation chute II that communicates the connecting hole II with the outside is provided on the connecting plate II. The installation chute I and the corresponding installation chute II are directly opposite in the front and back direction.

[0024] By adopting the above technical solution, by pulling the stoppers I and II away from each other, and then inserting the elastic telescopic rod into the connecting holes I and II through the installation chute I and the installation chute II, and releasing the stoppers I and II, the stoppers I and II can be pressed against the outer sides of the side plate and the main box body under the action of the elastic telescopic rod, so that the side plate and the main box body are connected together. When it is necessary to disassemble the side plate and the main box body, only need to pull the stoppers I and II away from each other, and then take out the elastic telescopic rod from the connecting holes I and II through the installation chute I and the installation chute II. The connection and disassembly methods between the side plate and the main box body are both simple.

[0025] Further, both the first connecting hole and the second connecting hole are strip-shaped. An unlocking hole communicating with the second connecting hole is provided at one end of the second connecting hole facing away from the second installation chute. The internal dimension of the unlocking hole is larger than the external dimension of the second stopper. When the casting box body is turned 90 degrees so that the side plate faces downwards, the connecting piece can move towards the unlocking hole to make the second stopper opposite to the unlocking hole, so that the main box body can be separated from the side plate.

[0026] With the above technical solution, when the connecting piece moves to a position corresponding to the second stopper and the unlocking hole, a pulling force away from each other is applied to the main box body and the side plate, so that the second stopper can pass through the unlocking hole and be separated from the main box body, and the method of separating the side plate from the main box body is more convenient.

[0027] Further, the aerated concrete block casting device further includes a demoulding conveying plate. A plurality of guiding insertion holes are provided on the demoulding conveying plate. A plurality of guiding columns extending forward and backward are provided on the side plate. A pushing slope is further provided on the demoulding conveying plate. A pushing inclined surface capable of fitting with the slope surface of the pushing slope is provided on the first stopper. The casting box body can be placed above the demoulding conveying plate after being turned 90 degrees so that the side plate faces downwards, so that each guiding column is correspondingly inserted into each guiding insertion hole, and at the same time, the pushing slope pushes the first stopper towards the unlocking hole through the pushing inclined surface during the falling process of the casting box body to drive the second stopper towards the unlocking hole.

[0028] With the above technical solution, when the slurry needs to be demoulded after being initially cured in the casting box body, only need to use the handling mechanism to turn the casting box body 90 degrees and then place it on the demoulding conveying plate. During the process of the casting box body falling onto the demoulding conveying plate, the first stopper moves towards the unlocking hole under the action of the pushing slope, and drives the second stopper towards the unlocking hole through the elastic telescopic rod. Therefore, as long as the casting box body is turned 90 degrees and then placed on the demoulding conveying plate, the automatic separation of the side plate and the main box body can be realized. Then, the main box body is lifted upwards to realize demoulding. The demoulding method is more convenient. Compared with the structure in the prior art that uses power components such as cylinders to press the side plate against the main box body and controls the action of the cylinder to separate the side plate from the main box body during demoulding, the structure of the present invention is simpler and can save power costs.

[0029] Further, an elastic telescopic push rod extending along the hole length direction of the first connecting hole is provided in the first connecting hole. One end of the elastic telescopic push rod facing away from the first installation chute is fixedly connected to the hole wall of the first connecting hole. One end of the elastic telescopic push rod facing the first installation chute is connected with a guiding block, and a guiding inclined surface is provided on one side of the guiding block facing the first installation chute.

[0030] With the above technical solution, by providing the elastic telescopic push rod, the connecting piece passing through the first connecting hole is pushed, so that the connecting piece is more firmly held at one end of the first connecting hole away from the unlocking hole when not affected by external force, preventing the first connecting piece from sliding along the hole length direction of the first connecting hole.

[0031] Further, an unlocking groove is provided on the demolding conveying plate, and the pushing ramp is arranged inside the unlocking groove.

[0032] The beneficial effects of the aerated concrete block casting device provided by the present invention are as follows: By providing a scraper, the present invention can automatically scrape the slurry attached to the outside of the vibrating rod during the upward movement of the vibrating mechanism, can timely clean the slurry attached to the outside of the vibrating rod, and avoid a series of adverse effects caused by the long-term adhesion of the slurry to the outside of the vibrating rod. After the casting box body is rotated 90 degrees and placed on the demolding conveying plate, the present invention can realize the automatic separation of the side plate and the main box body. The separation method of the side plate and the main box body is simpler, and there is no need to set a power element to press the side plate on the main box body, which can save power costs.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0046] The following is one of the embodiments of a aerated concrete block pouring device provided by the present invention:

[0047] As Figures 1 - 10 shown, a aerated concrete block pouring device includes a working support 1, a pouring box body, a connecting member, a demoulding and conveying plate 4, a grouting mechanism, a vibrating mechanism, a scraper 8, a sliding block 26 and a cleaning mechanism.

[0048] As Figure 1 , Figure 2 , Figure 4 , Figure 10As shown, the working bracket 1 is arranged on the horizontal ground. The working bracket 1 includes a base 101 and two vertical rods 102 connected to the base 101 and extending vertically. A support rod 19 is vertically connected to the front side of each vertical rod 102. The support rod 19 is located above the pouring box body, and a sliding slot 191 extending horizontally is provided on the front side of the support rod 19. A support seat 23 is connected to the rear side of each vertical rod 102, and the support seat 23 corresponds to the support rod 19 in the front-rear direction.

[0049] As Figure 1 、 Figure 2 shown, the pouring box body is arranged above the base 101. The top end of the pouring box body is provided with an opening. The pouring box body includes a main box body 2 and side plates 3.

[0050] Openings are provided at the top end and the front side of the main box body 2. Two connecting plates two 15 are symmetrically arranged on the left and right sides of the main box body 2. Three connecting holes two 151 are arranged at intervals up and down and penetrate through in the front-rear direction on the connecting plates two 15. The connecting holes two 151 are strip-shaped and extend vertically. As Figure 3 shown, an installation chute two 152 communicating the connecting hole two 151 with the outside is provided at the top end of each connecting hole two 151, and an unlocking hole 153 communicating with the connecting hole two 151 is provided at the bottom end of each connecting hole two 151.

[0051] The side plate 3 can be detachably installed on the front side of the main box body 2 to block the front side opening of the main box body 2. Four guide posts 13 extending horizontally are provided at the four corners of the front side of the side plate 3. Two connecting plates one 14 are symmetrically arranged on the left and right sides of the side plate 3. Three connecting holes one 141 are arranged at intervals up and down and penetrate through in the front-rear direction on the connecting plates one 14. The connecting holes one 141 are strip-shaped and extend vertically. As Figure 3 shown, an installation chute one 142 communicating the connecting hole one 141 with the outside is provided at the top end of each connecting hole one 141. The connecting holes one 141 on the same side are opposite to the connecting holes two 151 in the front-rear direction, and the installation chutes one 142 on the same side are opposite to the installation chutes two 152 in the front-rear direction. As Figure 6 shown, an elastic telescopic push rod 27 extending vertically is further provided in the connecting hole one 141. The bottom end of the elastic telescopic push rod 27 is fixedly connected to the bottom hole wall of the connecting hole one 141. The top end of the elastic telescopic push rod 27 is connected with a guiding push block 28. The top end of the guiding push block 28 is higher than the bottom surface of the installation chute one 142. A guiding inclined surface 281 is provided on the side of the guiding push block 28 facing the installation chute one 142. The guiding inclined surface 281 inclines downward towards the installation chute one 142 from top to bottom, and the bottom end of the guiding inclined surface 281 is lower than the bottom surface of the installation chute one 142.

[0052] Six connecting pieces are provided. The side plate 3 and the main box body 2 are detachably connected together through the six connecting pieces. As Figure 7 、 Figure 8As shown, the connecting member includes an elastic telescopic rod 34, a first stopper 29, a second stopper 31, and a limiting block 30. The elastic telescopic rod 34 extends in the front-rear direction. The first stopper 29 is connected to the front end of the elastic telescopic rod 34, and a pushing slope 291 that inclines forward from top to bottom is provided on the front side of the first stopper 29. The second stopper 31 is connected to the rear end of the elastic telescopic rod 34, a pull ring 32 is installed on the rear side of the second stopper 31, and the limiting block 30 is connected to the elastic telescopic rod 34 and is located between the first stopper 29 and the second stopper 31.

[0053] When assembling the side plate 3 and the main box body 2, by pulling the first stopper 29 and the pull ring 32, the first stopper 29 and the second stopper 31 are moved away from each other, and then the elastic telescopic rod 34 is pushed into the first connecting hole 141 and the second connecting hole 151 through the corresponding front-rear mounting chutes 142 and 152. While pushing, the first connecting plate 14 is stuck between the first stopper 29 and the limiting block 30. After that, the first stopper 29 and the pull ring 32 are released, and the first stopper 29 and the second stopper 31 are respectively pressed against the first connecting plate 14 and the second connecting plate 15, thus completing the connection and assembly between the side plate 3 and the main box body 2. During the process of pushing the elastic telescopic rod 34 from the mounting chute 142 into the first connecting hole 141, the elastic telescopic rod 34 pushes the guiding push block 28 downward through the guiding slope, thereby driving the elastic telescopic push rod 27 to contract. The elastic telescopic push rod 27 pushes the guiding push block 28 upward, so that the guiding push block 28 presses the elastic telescopic rod 34 against the top of the first connecting hole 141 from bottom to top, enabling the connecting member to be maintained at the position of the top of the first connecting hole 141.

[0054] As Figure 1 、 Figure 2 shown, the demolding conveyor plate 4 is located on the front side of the working bracket 1. A guiding jack 401 is provided at each of the four corners of the demolding conveyor plate 4. The four guiding jacks 401 correspond to the four guiding columns 13 one by one. After the casting box body is flipped 90 degrees, the four guiding columns 13 can be respectively inserted into the four guiding jacks 401. Three unlocking grooves 402 are further provided on each of the left and right sides of the demolding conveyor plate 4. Each unlocking groove 402 corresponds to each connecting member on the casting box body. A pushing slope 403 that inclines backward from top to bottom is provided in the unlocking groove 402.

[0055] After the four guiding columns 13 are inserted into the four guiding jacks 401, the first stoppers 29 in each connecting member can be respectively inserted into the unlocking grooves 402. The pushing slopes 291 on each first stopper 29 are in contact with the slopes of the pushing slopes 403. During the process of the casting box body and the connecting member falling onto the demolding conveyor plate 4, the pushing slope 403 pushes the first stopper 29 backward through the pushing slope 291. The first stopper 29 drives the elastic telescopic rod 34 and the second stopper 31 to move backward. Finally, the second stopper 31 moves to the unlocking hole 153. At this time, by lifting the main box body 2 upward, the main box body 2 can be separated from the side plate 3.

[0056] As shown in Figure 1 , Figure 2 , Figure 5 the grouting mechanism includes a slurry outlet pipe 6. The slurry outlet pipe 6 includes a vertically extending main slurry outlet pipe 601 and two auxiliary slurry outlet pipes 602 connected to the bottom of the main slurry outlet pipe 601 and communicating with the inner cavity of the main slurry outlet pipe 601. The two auxiliary slurry outlet pipes 602 are respectively inclined and connected to the left and right sides of the main slurry outlet pipe 601.

[0057] The vibrating mechanism includes a mounting frame 5 and vibrating rods 7. The mounting frame 5 is slidably mounted on the working support 1 through two sliding members. The sliding members include a connecting rod 10 and a sliding sleeve 11. The connecting rod 10 extends forward and backward. The connecting rod 10 is connected to the rear side of the mounting frame 5. The sliding sleeve 11 is connected to the rear end of the connecting rod 10. The sliding sleeve 11 is slidably sleeved on the vertical rod 102. A horizontally arranged support plate 12 is further connected to the rear side of the sliding sleeve 11. The above-mentioned main slurry outlet pipe 601 is connected to the mounting frame 5 through a connecting block 36. When the mounting frame 5 moves up and down, it can drive the slurry outlet pipe 6 to move up and down synchronously.

[0058] There are multiple vibrating rods 7. The multiple vibrating rods 7 all extend vertically. The multiple vibrating rods 7 are all mounted at the bottom of the mounting frame 5. The vibrating rods 7 can be inserted into the slurry in the pouring box and generate high-frequency vibrations to eliminate the air bubbles in the slurry. The vibrating rods 7 are of the prior art and the structure thereof will not be introduced in detail here.

[0059] A scraper 8 is arranged below the mounting frame 5 in parallel with the mounting frame 5. The scraper 8 is slidably sleeved on the outside of the multiple vibrating rods 7. An elastic member 9 is connected between the scraper 8 and the mounting frame 5. The elastic member 9 is a compression spring that can elastically expand and contract up and down.

[0060] As shown in Figure 5 , Figure 9 , Figure 10 There are two sliding blocks 26. The two sliding blocks 26 are respectively slidably inserted into the sliding slots 191 on the two support rods 19 in the front and rear directions. An elastic member 33 is connected between the sliding block 26 and the bottom surface of the sliding slot 191. The elastic member 33 is a compression spring that can expand and contract in the front and rear directions. A pushing inclined surface 262 is further arranged on the front side of the sliding block 26. The pushing inclined surface 262 slopes forward from top to bottom. When the elastic member 33 is in the natural state, the sliding block 26 and the scraper 8 are in an up-and-down blocking state. When the scraper 8 moves downward, it can push the sliding block 26 to move backward through the pushing inclined surface 262, so as to move past the sliding block 26 and move to the lower side of the sliding block 26. When the scraper 8 moves upward again, it will be blocked by the sliding block 26.

[0061] After the scraping plate 8 moves past the sliding stop block 26 and moves below the sliding stop block 26, its bottom surface is almost flush with the top surface of the casting box body. There is no large gap between the scraping plate 8 and the casting box body, preventing the slurry scraped off from impacting the slurry inside the casting box body when it falls and causing the slurry to splash outside the casting box body through the gap between the scraping plate 8 and the casting box body.

[0062] Both of the two sliding stop blocks 26 are in transmission connection with the mounting frame 5. The specific transmission connection method is as follows: The sliding stop block 26 is provided with a plug-in slot 261 with an opening facing backward. The rear end of the plug-in slot 261 is provided with a limiting hole that communicates with the inner cavity of the plug-in slot 261 and has an inner diameter smaller than the inner diameter of the plug-in slot 261. A pull rod 25 extending forward and backward is also slidably inserted inside the support rod 19. The front end of the pull rod 25 is vertically connected with a pull plate 35. The pull plate 35 is slidably inserted inside the plug-in slot 261. The outer diameter of the pull plate 35 is larger than the aperture of the limiting hole. The pull plate 35 can slide forward and backward inside the plug-in slot 261 and will not fall off from the plug-in slot 261. As Figure 4 shown, the rear end of the pull rod 25 is connected with a rack 21. The rack 21 is slidably mounted on the support seat 23. A gear 22 is also provided on the support seat 23. A spiral sleeve 24 is coaxially fixed to the bottom of the gear 22. The spiral sleeve 24 is rotatably mounted on the support seat 23. A transmission rod 20 is vertically connected to the above-mentioned support plate 12. A spiral mating section is provided on the transmission rod 20. The transmission rod 20 passes through the gear 22 and the spiral sleeve 24 from top to bottom in sequence. When the mounting frame 5 moves upward to a set position, the spiral mating section moves to a position corresponding to the spiral sleeve 24 and is in spiral transmission cooperation with the spiral sleeve 24, so as to be able to drive the gear 22 to rotate when the mounting frame 5 moves upward, and then drive the rack 21 to move backward. The rack 21 drives the pull rod 25 to move backward, and the pull rod 25 pulls the sliding stop block 26 to move backward, so that the scraping plate 8 located below the sliding stop block 26 is separated from the sliding stop block 26, and the scraping plate 8 moves upward and resets under the action of the first elastic member 9.

[0063] As Figure 1 、 Figure 2As shown in the figure, the cleaning mechanism includes a cleaning plate 16 and a cleaning plate driving assembly. The cleaning plate 16 extends forward and backward. The cleaning plate 16 is installed in the main box body 2 in a left-right guiding and sliding manner. The top end of the cleaning plate 16 is flush with the bottom surface of the scraping plate 8 blocked by the sliding block 26. The cleaning plate driving assembly includes a transmission screw 18 and a driving motor 17. The transmission screw 18 extends left and right and is rotatably installed at the rear side of the main box body 2. The driving motor 17 is fixedly installed on the main box body 2. The driving motor 17 is in transmission connection with the transmission screw 18 to drive the transmission screw 18 to rotate. The cleaning plate 16 is in screw transmission cooperation with the transmission screw 18. The driving motor 17 can drive the transmission screw 18 to rotate, and the transmission screw 18 can drive the cleaning plate 16 to move left and right to scrape the slurry adhered to the bottom surface of the scraping plate 8. Initially, the cleaning plate 16 is located on the right side of the main box body 2. The left side surface of the cleaning plate 16 is inclined downward and to the right from top to bottom, so as to facilitate the scraped slurry to slide down along the inclined surface.

[0064] When the present invention is in use, first, the inner side wall of the pouring box body is oiled. Then, the vibrating mechanism is driven to move downward. The vibrating mechanism drives the slurry outlet pipe 6 in the grouting mechanism to move downward. The vibrating rod 7 and the slurry outlet pipe 6 move into the inner cavity of the pouring box body. During the downward movement, the scraping plate 8 moves downward synchronously with the mounting frame 5. The scraping plate 8 can push the sliding block 26 over the sliding block 26 by pushing against the inclined surface 262 of the top push, and the sliding block 26 does not affect the downward movement of the scraping plate 8.

[0065] Then, the grouting mechanism is started, and the slurry outlet pipe 6 starts to inject slurry into the pouring box body. After the slurry injection is completed, the vibrating mechanism is started, and the vibrating rod 7 vibrates the slurry to discharge the gas in the slurry. After the vibration ends, the mounting frame 5 moves upward, driving the slurry outlet pipe 6, the vibrating rod 7 and the scraping plate 8 to move upward. The scraping plate 8 is blocked by the sliding block 26 and cannot move upward synchronously with the mounting frame 5. During this process, the scraping plate 8 scrapes off the slurry attached to the vibrating rod 7.

[0066] When the mounting frame 5 moves upward until the bottom end of the vibrating rod 7 is flush with the bottom surface of the scraping plate 8, the upward movement is paused for a period of time. During this period, the driving motor 17 is started. The driving motor 17 drives the transmission screw 18 to rotate. The transmission screw 18 drives the cleaning plate 16 to move in the left-right direction. The cleaning plate 16 scrapes off the slurry attached to the bottom surface of the scraping plate 8, realizing the cleaning of the bottom surface of the scraping plate 8.

[0067] After the scraping plate 8 is cleaned, the driving motor 17 drives the cleaning plate 16 to reset. Then, the mounting frame 5 continues to move upward. The spiral matching section on the transmission rod 20 starts to be in spiral transmission cooperation with the spiral sleeve 24, driving the gear 22 to rotate. The gear 22 drives the rack 21 and the pull rod 25 to move backward. The pull rod 25 pulls the sliding block 26 to move backward. The sliding block 26 is separated from the scraping plate 8. The scraping plate 8 moves upward and resets under the action of the first elastic member 9.

[0068] After the grouting mechanism, the vibrating mechanism and the scraper 8 are completely reset, the casting box is pushed to the preliminary curing processing area, so that the slurry stands in the casting box for a period of time to be preliminarily cured. After the slurry is preliminarily cured, the turning mechanism is used to clamp the main box body 2, and the casting box is turned forward by 90 degrees, so that one side of the middle side plate 3 of the casting box faces downward, and the casting box is placed on the demoulding conveying plate 4. During the placement process, the guide post 13 is inserted into the guide jack 401 on the demoulding conveying plate 4, and each first stop block 29 is respectively inserted into each corresponding unlocking groove 402. The pushing inclined surface 291 on the first stop block 29 fits with the slope surface of the pushing ramp 403. Then the casting box continues to move downward by a certain distance. During the downward movement, the first stop block 29 is pushed by the pushing ramp 403 to move backward. The first stop block 29 drives the elastic telescopic rod 34 and the second stop block 31 to move backward. When the second stop block 31 moves to the position corresponding to the unlocking hole 153, at this time, the main box body 2 is lifted upward, and the main box body 2 is automatically separated from the side plate 3, and the solidified slurry is separated from the main box body 2, realizing demoulding.

[0069] After that, the demoulding conveying plate 4 is conveyed forward, driving the demoulded solid slurry forward to the cutting station for cutting treatment.

[0070] By setting structures such as the scraper 8, the present invention can realize the timely cleaning of the vibrating rod 7, avoid a series of adverse effects caused by the slurry adhering to the outside of the vibrating rod 7. After the slurry is preliminarily cured in the present invention, after the casting box is turned over and placed on the demoulding conveying plate 4, the automatic separation of the side plate 3 and the main box body 2 can be realized. The structure is simple and the demoulding efficiency is higher.

[0071] In this embodiment, a cleaning mechanism is further provided on the casting box. After the scraper 8 scrapes off the slurry adhering to the vibrating rod 7, the cleaning plate 16 can clean the slurry on the scraper 8, avoiding the slurry being brought to the vibrating rod 7 again. In other embodiments, the cleaning mechanism may not be provided. At this time, the slurry adhering to the bottom surface of the scraper 8 can be scraped off manually using a scraping tool.

[0072] In this embodiment, the slurry outlet pipe 6 is connected to the mounting bracket 5 through the connecting block 36, so that the slurry outlet pipe 6 can move up and down synchronously with the mounting member. In other embodiments, the slurry outlet pipe 6 is not connected to the mounting bracket 5. At this time, a lifting mechanism needs to be separately provided to control the up and down movement of the slurry outlet pipe 6.

[0073] In this embodiment, an elastic telescopic push rod 27 extending vertically is provided in the first connecting hole 141. The elastic telescopic push rod 27 can prevent the connecting member from moving downward. In other embodiments, the elastic telescopic push rod 27 is not provided in the first connecting hole 141. At this time, the elastic telescopic rod 34 needs to have a greater elastic force to make the first stop block 29 and the second stop block 31 press more firmly on the first connecting plate 14 and the second connecting plate 15, ensuring that the connecting member will not move downward.
