[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example: Figure 1-Figure 12 As shown, the present invention provides a technical solution for an aerated concrete block forming method with a mold frame cleaning function, which is as follows:

[0032] In the injection structure 1, a plurality of supporting legs 12 are installed at the bottom of the conveying device 11, and the plurality of supporting legs 12 support the conveying device 11 so that the conveying device 11 is at a certain distance from the ground. A plurality of mounting ear plates 14 are fixedly installed on the outside of the mixing tank 13, and the plurality of mounting ear plates 14 are used for fixing the mixing tank 13 to the building; a sludge pump 15 is fixedly installed at the discharge end of the mixing tank 13, and the working sludge pump 15 extracts concrete material from the inside of the mixing tank 13, and a telescopic pipe 17 is fixedly installed at the bottom end of the gate valve 16 fixedly installed at the discharge end of the sludge pump 15, and a discharge pipe 18 is fixedly installed at the bottom end of the telescopic pipe 17, and the sludge pump 15 is opened by the gate valve 16 when working. , a telescopic tube 17 and a discharge pipe 18 transport the concrete material to the interior of the forming mold 2; and a transmission frame 19 is fixedly sleeved on the outer side of the discharge pipe 18, and the outer wall of a pneumatic cylinder 110 fixedly connected to the top of the transmission frame 19 is fixedly connected to the outer wall of the sludge pump 15, so as to control the operation of the pneumatic cylinder 110, and the pneumatic cylinder 110 drives the discharge pipe 18 to move up and down through the transmission frame 19, so that the bottom end of the discharge pipe 18 is away from the forming mold 2 or inserted into the interior of the forming mold 2; a control device is installed on the conveying equipment 11 to control the automatic operation of the aerated concrete block forming equipment composed of the injection structure 1 and the demoulding structure 3, which is a conventional technical application and will not be elaborated here.

[0033] The steps for forming aerated concrete blocks are as follows:

[0034] Step 1: adding a certain amount of concrete raw materials and gas generating agent into the mixing tank 13, and the mixing tank 13 mixes the concrete raw materials and the gas generating agent;

[0035] Step 2: The conveying device 11 conveys the molding mold 2, one side of the mold frame 21 contacts the side frame of the conveying device 11, and the installation box 210 fixedly connected to the other side of the mold frame 21 contacts the side frame of the other side of the conveying device 11, so the mold frame 21 can only be transported by the conveying device 11 under normal circumstances. A fixing frame 113 is fixedly connected to one side of the conveying device 11, and a pressure sensor 112 is fixedly connected to one end of a pneumatic cylinder 111 fixedly connected to one end of the fixing frame 113. The pressure sensor 112 is located on the forward path of the molding mold 2. When the mold frame 21 in the molding mold 2 moves and contacts the pressure sensor 112, the control device electrically connected to the pressure sensor 112 receives feedback from the pressure sensor 112, and the control device controls the conveying device 11 to suspend work. At this time, the molding mold 2 enters the processing position, and the control device controls the pneumatic cylinder 111 to contract, and the pneumatic cylinder 111 drives the pressure sensor 112 to leave the movement path of the molding mold 2.

[0036] Step three: the control device controls the pneumatic cylinder 110 to extend, and the pneumatic cylinder 110 pushes the discharge pipe 18 downward through the transmission frame 19, so that the bottom end of the discharge pipe 18 is inserted into the feed port 22 opened on the side of the top of the mold frame 21 close to the pressure plate 24, and then controls the gate valve 16 to work and open for a period of time, and controls the sludge pump 15 to work for a period of time, and the sludge pump 15, the gate valve 16, the telescopic tube 17, the discharge pipe 18 and other structures cooperate to inject a certain amount of concrete material into the mold frame 21. After the injection of the material into the mold frame 21 is completed, the pneumatic cylinder 110 contracts, and the pneumatic cylinder 110 drives the discharge pipe 18 to move upward through the transmission frame 19, so that the discharge pipe 18 is separated from the forming mold 2.

[0037] Since a baffle plate 27 is inserted on one side of the mold frame 21, a pressure plate 24 is provided on the side of the mold frame 21 away from the baffle plate 27, and the feed port 22 is provided between the pressure plate 24 and the baffle plate 27, the concrete material is confined between the pressure plate 24 and the baffle plate 27, thereby completing the work of injecting material into the molding mold 2.

[0038] Step four: the control device controls the pneumatic cylinder three 32 in the demolding structure 3 to work. Since the fixed frame two 31 fixedly mounted on the outer side of the pneumatic cylinder three 32 is fixedly connected to the conveying equipment 11, the pneumatic cylinder three 32 cannot move up and down. Since the pad 33 fixedly connected to the top of the working pneumatic cylinder three 32 is fixedly connected to the pneumatic cylinder four 35, the working pneumatic cylinder three 32 pushes the pneumatic cylinder four 35 to move upward, and the double-axis pneumatic cylinder 36 fixedly connected at one end of the pneumatic cylinder four 35 moves upward. When the pneumatic cylinder three 32 stops working, the pneumatic cylinder four 35 and the double-axis pneumatic cylinder 36 enter the working state.

[0039] Step 5: The control device controls the pneumatic cylinder 4 35 to work for the first time. The pneumatic cylinder 4 35 that works for the first time pushes the double-axis pneumatic cylinder 36 to move a certain distance toward the pressing plate 24, so that the double-axis pneumatic cylinder 36 moves to between the two transmission frames 25 that are fixedly connected to the side of the pressing plate 24 away from the baffle plate 27;

[0040] Two transmission frames 5 310 fixedly installed on one side of the double-axis pneumatic cylinder 36 in the pneumatic synchronization assembly move synchronously for a distance. Since one end of the telescopic air storage member 311 fixedly installed on one side of the two transmission frames 5 310 is fixedly connected to a fixed frame 3 312, the fixed frame 312 is fixedly connected to an air guide pipe 1 313 for guiding air, and an air guide pipe 2 314 is fixedly connected between the two air guide pipes 1 313, and a plurality of springs 2 315 fixedly connected to one side of the air guide pipe 2 314 are fixedly installed with a fixed frame 5 317 at one end, and the fixed frame 5 317 is fixedly installed with a fixed frame 4 316 fixedly connected to the outer shell of the pneumatic cylinder 4 35. At this time, the pulling force applied to the air guide pipe 2 314 by the plurality of springs 2 315 is greater than that of the telescopic air storage member 311. The force required for contraction is required, so the moving transmission frame 5 310 causes the telescopic gas storage member 311 to contract to a certain length, and the gas inside the telescopic gas storage member 311 enters the interior of the air guide pipe 2 314 through the air guide pipe 1 313. In addition, because the top of the air guide pipe 2 314 is fixedly connected with the air guide pipe 3 318, one end of the air guide pipe 318 is fixedly connected with the telescopic pipe 2 319 that can be telescoped, and a plurality of mounting short rods 321 are fixedly connected between the junction box 320 fixedly connected to one end of the telescopic pipe 2 319 and the pneumatic telescopic rod 1 322, the upper and lower positions of the junction box 320 are limited by the shell of the pneumatic telescopic rod 1 322, and the shell of the pneumatic telescopic rod 1 322 is fixedly connected to the outer wall of the sludge pump 15, so the junction box 320 cannot move up and down;

[0041] The second pneumatic telescopic rod 326 is provided with a hose 325, and the air pressure inside the second pneumatic telescopic rod 326 increases. The second pneumatic telescopic rod 326 extends to push the transmission frame 7 328 fixedly connected to the piston end to move. The two plug plates 330 fixedly installed on one side of the transmission frame 7 328 are inserted into the two plug holes 28 provided on the baffle plate 27. At this time, the plug plates 330 limit the left and right and up and down movements of the baffle plate 27, and the transmission frame 7 328 supports the top of one side of the baffle plate 27. The bottom of one side of the mold frame 21 contacts the side frame of the conveying device 11 and is limited, so that the mold frame 21 is supported and stably arranged on the top of the conveying device 11, so as to avoid the possibility of the mold frame 21 tipping over when the subsequent pressing plate 24 moves toward the baffle plate 27 to shape the concrete material between the pressing plate 24 and the baffle plate 27, thereby ensuring the stability of the aerated concrete block forming.

[0042] And the top of the transmission frame eight 332 in the positioning assembly is arranged inside the transmission frame seven 328, so the transmission frame seven 328 drives the transmission frame eight 332 to move horizontally synchronously, and the bottom of the transmission frame eight 332 is fixedly connected to the transmission frame nine 333, and one side of the transmission frame nine 333 is fixedly connected to the insertion rod 336 and the telescopic rod 334, the friction sleeve 335 sleeved on the outer side of the insertion rod 336 is fixedly connected to the conveying device 11, and the telescopic rod 334 that can be telescoped is fixedly connected to the conveying device 11. Under the limitation of the friction sleeve 335 and the telescopic rod 334, the transmission frame eight 332 can only move horizontally. After the movement of the transmission frame eight 332, the insertion rod 336 is partially inserted into the transmission frame three 29 fixedly connected to the outer side of the mold frame 21, as shown in FIG. Figure 8 As shown, the insert rod 336 cannot move up and down, the transmission frame three 29 cannot move up and down at this time, and the mold frame 21 cannot move up and down at this time. When the pneumatic cylinder four 35 works to push the dual-axis pneumatic cylinder 36 to the working position, under the control of the pneumatic synchronization component, the two positioning components, the pneumatic telescopic rod two 326, the transmission frame seven 328, the insert plate 330 and other structures cooperate to limit the up and down movement of the mold frame 21, and the top side of the baffle plate 27 is supported, so that the mold frame 21 is stably stressed under the support of the transmission frame seven 328 and the conveying equipment 11, and at the same time, the transmission relationship between the baffle plate 27 and the transmission frame six 327 fixedly mounted on the outside of the pneumatic telescopic rod two 326 is completed.

[0043] Step 6: The control device controls the double-axis pneumatic cylinder 36 to work, so that the double-axis pneumatic cylinder 36 pushes the two guide rods 3 37 fixedly connected at the two piston ends, and the guide rod 3 37 moves toward the adjacent transmission frame 2 25. The outer diameter of the guide rod 3 37 is the same as the inner diameter of the transmission frame 25. One end of the guide rod 3 37 enters the interior of the transmission frame 25. At the same time, the guide rod 3 37 moves away from the support frame 38 fixedly connected to one end of the double-axis pneumatic cylinder 36 toward the adjacent friction limit assembly;

[0044] Since the force rod 214 in the friction limit assembly is fixedly connected to the pressing plate 24, two arc-shaped friction plates 212 are sleeved on the outside of the force rod 214, and the side of the arc-shaped friction plate 212 away from the force rod 214 is fixedly connected to the transmission frame 4 211, and the installation box 210 sleeved on the outside of the transmission frame 4 211 is fixedly connected to the mold frame 21, so the transmission frame 4 211 moves up and down under the limit of the installation box 210, and a plurality of elastic springs are fixedly connected between the installation box 210 and the transmission frame 4 211. Spring 1 213, spring 1 213 applies thrust to transmission frame 4 211 and arc friction plate 212, so that there is a large friction between arc friction plate 212 and force rod 214, force rod 214 and pressure plate 24 fixedly connected to force rod 214 are limited, pressure plate 24 can move only after receiving a certain force, avoid pressure plate 24 and baffle plate 27 cooperate to shape concrete material in the process of pressure plate 24 under the influence of concrete material displacement, to ensure the quality of aerated concrete block forming;

[0045] In addition, the two arcuate friction plates 212 are provided with inclined grooves 215 on one side close to the transmission frame 25, and the two inclined grooves 215 constitute a trapezoidal space. The end of the trapezoidal space close to the support frame 38 is a larger end. The support frame 38 that moves synchronously with the guide rod 37 has an arc surface facing the arcuate friction plate 212. When the guide rod 37 stops moving, the support frame 38 enters the trapezoidal space to spread the two arcuate friction plates 212 apart, and the arcuate friction plates 212 are out of contact with the force-bearing rod 214. During the control process of the demolding structure 3 on the pressing plate 24, no wear will occur between the force-bearing rod 214 and the arcuate friction plates 212.

[0046] Step 7: The pneumatic cylinder 4 35 works for the second time. At this time, the pneumatic cylinder 4 35 pushes the double-axis pneumatic cylinder 36 to move a certain distance into the mold frame 21. The double-axis pneumatic cylinder 36 pushes the pressing plate 24 to move through the guide rod 3 37 and the transmission frame 2 25 sleeved on the outside of the guide rod 3 37. Since the concrete material injected into the mold frame 21 is quantitative and the internal space of the mold frame 21 is uniform in size, the pressing plate 24 pushes the concrete material inside the mold frame 21. Under the action of the pressing plate 24, the concrete material moves toward the baffle plate 27. Finally, under the action of the mold frame 21, the pressing plate 24 and the baffle plate 27, the concrete becomes a square block. The square block is formed in a relatively sealed environment. The gas generated by the gas generating agent in the concrete material is blocked inside the square block, so that bubbles appear inside the square block to form an aerated concrete block.

[0047] When the pressing plate 24 does not move to the side of the bottom of the feed inlet 22 close to the baffle plate 27, the concrete material inside the mold frame 21 is relatively dispersed, and the height of the concrete material inside the mold frame 21 is not enough to leave the feed inlet 22;

[0048] During the second operation of the pneumatic cylinder four 35, the solenoid valve 323 fixedly connected to the bottom of the junction box 320 is not working and is in a closed state. The pneumatic telescopic rod two 326 has reached its extension limit, so the telescopic air storage part 311 cannot continue to contract. The spring two 315 extends to meet the needs of synchronous movement of the fixed frame three 312 and the transmission frame five 310.

[0049] Step 8: The air cylinder 4 35 stops working for a period of time so that the pressing plate 24 is subjected to sufficient force and the square block is initially formed.

[0050] Step nine: The double-axis pneumatic cylinder 36 works and contracts, so that the guide rod three 37 and the support frame 38 move to between the two transmission frames two 25, and the two arc-shaped friction plates 212 lose support. The multiple springs one 213 rebound to make the arc-shaped friction plate 212 move to the outside of the force-bearing rod 214 again. The spring one 213 and the arc-shaped friction plate 212 cooperate to limit the force-bearing rod 214, and the pressure plate 24 fixedly connected to the force-bearing rod 214 is limited to maintain its original state; the pneumatic cylinder four 35 works and contracts, and then the pneumatic cylinder three 32 contracts and the pneumatic cylinder four 35 moves downward, and the pneumatic cylinder four 35 leaves the movement track of the force-bearing rod 214; when the pneumatic cylinder four 35 contracts, the telescopic air storage member 3 11 loses extrusion, the air pressure inside the pneumatic telescopic rod 2 326 is restored, one end of the spring 331 fixedly connected to one side of the transmission frame 7 328 is fixedly connected to the transmission frame 6 327, and the pneumatic telescopic rod 2 326 contracts under the contraction force and negative pressure of the spring 331, and the pneumatic telescopic rod 2 326 drives the transmission frame 7 328 and the plug plate 330 fixedly connected to the transmission frame 7 328 to move, and the plug plate 330 moves out of the plug hole 28; at the same time, the transmission frame 7 328 drives the transmission frame 8 332 to move, and the transmission frame 9 333 drives the plug rod 336 to leave the transmission frame 3 29, and the limit imposed on the molding mold 2 by the demoulding structure 3 is completely removed.

[0051] Step 10: Control the conveying device 11 to convey the forming mold 2, and convey the forming mold 2 to the waiting area for stacking, waiting for the aerated concrete blocks to be completely formed.

[0052] Step 11: The forming mold 2 is re-placed on the conveying device 11 for transportation. The conveying device 11 transports the forming mold 2 toward the demolding structure 3. When the mold frame 21 moves and contacts the pressure sensor 112, the control device controls the conveying device 11 to stop working and controls the second pneumatic cylinder 111 to contract. The second pneumatic cylinder 111 drives the pressure sensor 112 to leave one side of the forming mold 2.

[0053] Step 12: Control the solenoid valve 323 to open, control the pneumatic cylinder 4 35 to work for the first time, and the pneumatic cylinder 4 35 pushes the double-axis pneumatic cylinder 36 to move a distance toward the pressing plate 24, so that the double-axis pneumatic cylinder 36 moves to between the two transmission frames 25 fixedly connected to the side of the pressing plate 24 away from the baffle plate 27; after the pneumatic cylinder 4 35 is suspended from the initial work, control the double-axis pneumatic cylinder 36 to work, and the double-axis pneumatic cylinder 36 pushes the guide rod 3 37 to insert into the transmission frame 25, and the support frame 38 opens the two arc-shaped friction plates 212 on the outer side of the force-bearing rod 214, and the force-bearing rod 214 loses its limit;

[0054] During the movement of the double-axis pneumatic cylinder 36, the two transmission frames 5 310 fixedly connected to the double-axis pneumatic cylinder 36 squeeze the two telescopic gas storage members 311, and the gas inside the two telescopic gas storage members 311 enters the interior of the junction box 320 under the action of the two air guide pipes 1 313, the air guide pipe 2 314, the air guide pipe 3 318, and the telescopic pipe 2 319, because the air pressure required for the contraction of the pneumatic telescopic rod 1 322 is higher than the air pressure required for the extension of the pneumatic telescopic rod 2 326;

[0055] Therefore, at the initial stage when the transmission frame five 310 squeezes the telescopic gas storage member 311, the internal air pressure of the junction box 320 is insufficient, and the internal gas of the junction box 320 enters the inside of the pneumatic telescopic rod two 326 through the hose 325. The pneumatic telescopic rod two 326 extends to make the plug plate 330 fixedly connected to the transmission frame seven 328 enter the inside of the plug hole 28 opened in the material blocking plate 27, and at the same time, the two plug rods 336 are inserted into the two transmission frames three 29 fixedly connected to the mold frame 21, and the mold frame 21 is limited in its up and down movement. At this time, the vertical plate 39 fixedly connected to the bottom of the double-axis pneumatic cylinder 36 enters the mold frame 21 and contacts the bottom wall of the inner cavity of the mold frame 21, so that both ends of the mold frame 21 have force points for limiting the up and down movement, thereby ensuring the stability of the mold frame 21 demoulding on the conveying equipment 11;

[0056] At the later stage of the transmission frame five 310 squeezing the telescopic air storage part 311, the pneumatic telescopic rod two 326 extends to the limit, and the air pressure inside the junction box 320 reaches the contraction pressure of the pneumatic telescopic rod one 322, and the air flow inside the junction box 320 passes through the solenoid valve 323 and the air guide pipe four 324, and the contraction of the pneumatic telescopic rod one 322 drives the transmission frame six 327 fixed at the bottom end to move upward, and the transmission frame six 327 drives the pneumatic telescopic rod two 326 and the transmission frame seven 328 to move upward, and the transmission frame seven 328 drives the baffle plate 27 to move upward through the plug plate 330, and the bottom end of the baffle plate 27 moves upward and enters the guide tube 26 fixedly connected to the mold frame 21, so that the end of the mold frame 21 away from the pressure plate 24 loses the obstruction, and the horizontal plane where the bottom wall of the inner cavity of the mold frame 21 is located is higher than the height of the frame of the conveying equipment 11, and the aerated concrete blocks inside the mold frame 21 can directly leave the top of the conveying equipment 11.

[0057] After the initial operation of the pneumatic cylinder 435 is suspended, the telescopic air storage member 311 is compressed to the limit.

[0058] Step 13: The pneumatic cylinder 4 35 works again, and the spring 2 315 extends to meet the need of the transmission frame 5 310 to continue to move. The pneumatic cylinder 4 35 pushes the pressing plate 24 to move through the dual-axis pneumatic cylinder 36, the guide rod 3 37, and the transmission frame 25. The moving pressing plate 24 pushes the air concrete block out of the mold frame 21, completing the demoulding of the air concrete block.

[0059] When the pneumatic cylinder 4 35 drives the double-axis pneumatic cylinder 36 to reset, due to the limited movement speed of the transmission frame 5 310 and the limited extension speed of the telescopic gas storage member 311, the high-pressure gas inside the pneumatic telescopic rod 1 322 flows back to the inside of the junction box 320, and the internal air pressure of the junction box 320 still meets the extension needs of the pneumatic telescopic rod 2 326 with lower air pressure, so that the pneumatic telescopic rod 2 326 remains in an extended state, and the plug plate 330 remains in a state set inside the plug hole 28. At this time, the pneumatic telescopic rod 1 322 extends under the action of the internal negative pressure, and the force generated by the extension of the pneumatic telescopic rod 1 322 is transmitted through The transmission frame six 327, the pneumatic telescopic rod two 326, the transmission frame seven 328, and the plug plate 330 act on the baffle plate 27, and the baffle plate 27 moves down and resets. When the high-pressure gas inside the pneumatic telescopic rod one 322 completely flows back into the telescopic gas storage part 311, the transmission frame seven 328 moves down and is mounted on the outer top of the transmission frame eight 332. As the telescopic gas storage part 311 continues to extend, the low-pressure gas inside the pneumatic telescopic rod two 326 flows back, causing the pneumatic telescopic rod two 326 to contract, the plug plate 330 leaves the inside of the plug hole 28, and the transmission frame eight 332 drives the plug rod 336 to leave the inside of the transmission frame three 29.

[0060] In summary, the forming mold 2 is transported and positioned by the injection structure 1, and while the injection structure 1 is injecting material into the inside of the forming mold 2, the demoulding structure 3 performs corresponding work to shape the concrete material entering the inside of the forming mold 2, and during the shaping process, the support of the forming mold 2 is limited, so as to prevent the forming mold 2 from tipping over without making adaptability improvements to the conveying equipment 11.

[0061] It is only necessary to control the working steps of the pneumatic cylinder 435 and the electromagnetic valve 323 to make the demoulding structure 3 meet the needs of shaping the concrete material inside the forming mold 2 and demoulding the air concrete blocks inside the forming mold 2, thereby ensuring the applicable scope of the demoulding structure 3 and reducing the equipment cost investment; in the process of the baffle plate 27 moving up to provide a channel for demoulding the aerated concrete blocks, the outer side of the baffle plate 27 is cleaned by friction with the mold frame 21, and the pressing plate 24 pushes the air concrete blocks inside the mold frame 21 for demoulding. The pressing plate 24 that is in contact with the inner wall of the mold frame 21 cleans the inside of the mold frame 21, and the force of the demoulding aerated concrete blocks is directly used to clean the inside of the mold frame 21, thereby reducing the time cost investment required for the forming mold 2 to be put into use again.

[0062] In addition, such as Figure 8 and Fig.10As shown, a plurality of guide rods 2 329 are inserted into the transmission frame 6 327, and one end of the guide rod 2 329 is fixedly connected to the transmission frame 7 328. The force of the up and down movement of the transmission frame 6 327 acts on the transmission frame 7 328 through the guide rod 2 329, thereby reducing the force on the pneumatic telescopic rod 2 326 and protecting the pneumatic telescopic rod 2 326. In addition, a groove is provided on the transmission frame 6 327, and one end of the spring 331 is arranged inside the groove, thereby reducing the space required for the installation of the spring 331.

[0063] In addition, one end of the telescopic tube 2 319 is connected to the junction box 320 through a reversing pipe joint, so that the angle of the telescopic tube 2 319 can be changed to meet the needs of the air guide tube 3 318 to move up and down.

[0064] A friction sleeve 335 is sleeved on the outer side of the insertion rod 336. The friction sleeve 335 applies a certain friction force to the insertion rod 336, so that the insertion rod 336 can move only after being subjected to a certain force.

[0065] In addition, such as Figure 5 As shown, a fixing frame 6 23 is provided on one side of the pressing plate 24 away from the baffle plate 27 , and the fixing frame 6 23 is fixedly connected to the mold frame 21 to limit the pressing plate 24 , so that the pressing plate 24 cannot leave the interior of the mold frame 21 .

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
