Description

Technical Field

[0001] This invention relates to the field of thermal insulation brick manufacturing technology, and more specifically, to a thermal insulation brick pressing and molding equipment and its usage method. Background Technology

[0002] Thermal insulation bricks, as an important building energy-saving material, are typically designed with a porous structure to achieve lightweight and heat-insulating properties. Currently, these bricks are mostly produced using a compression molding process, and the core equipment usually includes molds, press heads, and core rods used to form the pores.

[0003] In existing technologies, such pressing and molding equipment and methods have several shortcomings that urgently need improvement: First, during the demolding process, significant friction and adhesion can easily occur between the core rod used to form the holes and the cured brick. Forcibly removing it can easily damage the internal pore walls of the brick or cause cracks, affecting the finished product's pass rate. Second, to facilitate demolding, some methods pre-apply a release agent to the surface of the core rod; however, uneven application and inaccurate dosage control can lead to waste or contamination. After the brick is pressed, its bottom may form a vacuum due to tight adhesion with the bottom of the mold cavity, generating significant demolding resistance, making it difficult to remove the brick, and even causing the brick to break during demolding. Third, the core rod is mostly fixed or involves simple linear motion, resulting in poor adaptability to brick materials during molding and demolding, affecting the quality and efficiency of hole formation.

[0004] Therefore, a heat-insulating brick pressing and molding equipment and its usage method are proposed. Summary of the Invention

[0011] Preferably, a guide rod is slidably connected to the upper end of the support plate, and the lower end of the guide rod is fixed to the upper end of the pressure block.

[0012] Preferably, the lower end of the base is uniformly and fixedly connected with support rods, the upper end of the support rods is fixed to the lower end of the horizontal plate, and the rod wall of the support rods is slidably connected to the lower end of the movable mold shell.

[0013] Preferably, cylinders are fixedly connected to both sides of the lower inner wall of the movable mold shell, a one-way valve is fixedly connected to the lower end of the cylinder, a piston block is slidably connected inside the cylinder, an air pipe is fixedly connected inside the piston block, round blocks are fixedly connected to both sides of the upper end of the movable mold shell, a blocking block is provided at the upper end of the round block, a limiting block is fixedly connected to the lower end of the blocking block, and air holes are evenly opened at the upper end of the air pipe.

[0014] Preferably, a second spiral rod is rotatably connected to both sides of the inner wall of the movable mold shell. The rod wall of the second spiral rod is helically driven inside the horizontal plate. A first circular plate is fixedly connected to the lower end of the second spiral rod. A circular rod is uniformly slidably connected inside the first circular plate. A second circular plate is fixedly connected to the upper end of the circular rod. A fifth spring is fixedly connected to the lower end of the second circular plate. Friction blocks are fixedly connected to both the upper end of the second circular plate and the inside of the movable mold shell.

[0015] A method for using a heat-insulating brick pressing and molding equipment includes the following steps.

[0016] S1. Place the raw material inside the base, located at the upper end of the movable mold shell;

[0017] S2. Activate the hydraulic rod to move the pressure block downwards and press the raw material;

[0018] S3. The movable mold shell moves downward, exposing the perforated rod;

[0019] S4. Lubricating oil is sprayed out through the first liquid hole, and the lubricating oil is located on the outside of the opening rod;

[0020] S5. The gear frame moves back and forth, causing the gear to drive the hole-opening rod to rotate in both directions.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1) During the brick pressing process, when the perforating rod extends into the raw material, the top rod disengages from contact. Under the action of the second spring, the piston plate presses down, forcing the lubricating oil in the liquid shell into the perforating rod through the liquid guide tube and cavity. When the pressing block is pressed into place, it will push the moving rod down, aligning the first liquid hole on the perforating rod with the second liquid hole on the moving rod, so that the lubricating oil can be evenly coated on the surface of the perforating rod. This design releases the lubricating oil only in the later stage of pressing, avoiding waste, and greatly reducing frictional resistance during demolding. It effectively prevents damage or cracking of the internal structure of the brick due to adhesion and friction, and improves the finished product qualification rate and demolding smoothness.

[0023] (2) The up-and-down movement of the moving mold shell drives the first auger to rotate the auger block and eccentric wheel. The eccentric wheel drives the gear frame to reciprocate back and forth, which in turn drives multiple gears to rotate synchronously and alternately in both directions. The gears drive the hole-opening rod to rotate in both directions during pressing and demolding. During pressing, the rotation helps the hole-opening rod to cut into the raw material more smoothly and evenly, forming regular hollow channels; during demolding, the rotational motion can effectively break the static friction, making it easier for the hole-opening rod to rotate out of the solidified brick, thereby improving the hole-forming quality and demolding efficiency.

[0024] (3) The equipment is designed with a pneumatic system consisting of a cylinder, piston block, air pipe, and one-way valve. When the moving mold shell moves downward, the one-way valve opens to draw in air; when the moving mold shell moves upward to demold, the cylinder moves upward relative to the piston block, compressing the air in the chamber. The pressurized gas is ejected through the air pipe and air hole, pushing open the block and entering the gap between the brick and the base. This process can inject gas into the bottom of the brick, effectively eliminating the vacuum negative pressure that may be formed due to the tight fit during demolding, solving the problem of the brick bottom being difficult to remove due to adsorption between the mold and the mold, significantly reducing demolding resistance, and making the brick removal easier and more complete.

[0025] (4) The relative movement between the moving mold shell and the fixed horizontal plate drives the second spiral rod to rotate, which in turn drives the first circular plate, the circular rod, and the second circular plate to rotate. Under the support of the fifth spring, the friction block at the upper end of the second circular plate generates intermittent friction with the friction block fixed inside the moving mold shell, thereby converting the rotational motion into periodic slight vibration of the entire moving mold shell. This vibration has a dual function: firstly, during the feeding stage, it helps the raw material to be automatically and evenly spread in the mold cavity, reducing manual intervention and creating conditions for pressing out brick blanks with uniform density; secondly, during the demolding stage, the vibration helps the bricks separate from the upper surface and side walls of the moving mold shell, assisting the bricks to detach from the mold and further ensuring the structural integrity of the bricks during the demolding process.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1 to 10 A heat-insulating brick pressing and forming equipment and its usage method are disclosed. The equipment includes a base 1, a support plate 2 fixedly connected to the upper end of the base 1, and hydraulic rods 3 fixedly connected to both sides of the inside of the support plate 2. The hydraulic rods 3 are driving devices, and the output end can move up and down. The output end of the hydraulic rods 3 is fixedly connected to a pressing block 5. The output end of the hydraulic rods 3 drives the pressing block 5 to move downward, thereby realizing the pressing and forming of the brick. A guide rod 4 is slidably connected to the upper end of the support plate 2. The guide rod 4 makes the pressing block 5 move more stably. The lower end of the guide rod 4 is fixed to the upper end of the pressing block 5. A hollow processing component is provided inside the base 1.

[0040] The hollow processing assembly includes a horizontal plate 8 fixedly connected to the inner wall of the base 1. The horizontal plate 8 is fixed to the inner wall of the base 1 so that it remains stationary during pressing. A movable mold shell 7 is slidably connected to the inner wall of the base 1. The movable mold shell 7 can move up and down on the inner wall of the base 1. The horizontal plate 8 is located inside the movable mold shell 7. Both sides of the horizontal plate 8 pass through the movable mold shell 7 and are fixedly connected to the inner wall of the base 1. A first spring 17 is fixedly connected to the lower ends of both sides of the horizontal plate 8. The lower end of the first spring 17 is fixedly connected to the lower inner wall of the movable mold shell 7. Perforated rods 9 are evenly arranged at the upper end of the horizontal plate 8. The rod wall of the perforated rod 9 is slidably connected to the upper end of the movable mold shell 7. Support rods 6 are evenly fixedly connected to the lower end of the base 1 to improve the stability of the horizontal plate 8. The upper end of the support rod 6 is fixed to the lower end of the horizontal plate 8, and the rod wall of the support rod 6 is slidably connected to the lower end of the movable mold shell 7.

[0041] During operation, the raw material to be molded is placed on the inner wall of the base 1. Then, the hydraulic rod 3 is activated. The output end of the hydraulic rod 3 drives the pressing block 5 to move downward. The pressing block 5 moves downward to press the raw material. When the pressing block 5 begins to contact the raw material, the raw material and the moving mold shell 7 move downward. As the moving mold shell 7 moves downward, the perforating rod 9 is fixedly connected to the horizontal plate 8, so it moves upward relative to the moving mold shell 7. This causes the perforating rod 9 to extend into the interior of the raw material, resulting in a hollow area inside the brick. The moving mold shell 7 moves upward relative to the horizontal plate 8. The downward movement stretches the first spring 17. When the molding process ends, the output end of the hydraulic rod 3 moves upward, and the hydraulic rod 3 drives the pressure block 5 to move upward. At this time, the upper end of the brick and the moving mold shell 7 are not subjected to the pressure of the pressure block 5. At this time, the moving mold shell 7 returns to its original position and moves upward under the action of the first spring 17, exerting an upward pushing force on the brick. At this time, the opening rod 9 moves downward relative to the moving mold shell 7 and retracts into the interior of the moving mold shell 7, so that the opening rod 9 can be pulled out from the interior of the brick, making it more convenient for workers to remove the brick.

[0042] like Figure 2 , Figure 3 and Figure 5As shown, a liquid housing 12 is fixedly connected to the lower end of the horizontal plate 8, and a hose 11 is fixedly connected to the lower end of the liquid housing 12. The hose 11 is used to transmit lubricating oil and has a control valve inside. A piston plate 14 is slidably connected inside the liquid housing 12. The piston plate 14 can slide inside the liquid housing 12. A second spring 16 is fixedly connected to both sides of the lower end of the piston plate 14. The second spring 16 exerts a downward pulling force on the piston plate 14. The lower end of the second spring 16 is fixedly connected to the lower inner wall of the liquid shell 12. The lower end of the piston plate 14 is fixedly connected to a push rod 15. The push rod 15 moves synchronously with the piston plate 14. The rod wall of the push rod 15 is slidably connected to the lower end of the liquid shell 12. Both sides of the liquid shell 12 are fixedly connected to liquid guide tubes 13 for transmitting liquid guide tubes 13. A cavity 41 is opened inside the horizontal plate 8. Lubricating oil is introduced into the cavity 41 through the liquid guide tube 13. The lower end of the perforated rod 9 is connected to the cavity 41. The cavity 41 is connected to the upper end of the liquid guide tube 13. The first liquid hole 21 is evenly opened inside the perforated rod 9. Liquid is discharged through the first liquid hole 21.

[0043] Initially, the movable mold shell 7 is located at the upper end of the inner wall of the base 1. At this time, the piston plate 14 is at the upper end relative to the liquid shell 12, and the lower end of the piston plate 14 is filled with a certain amount of lubricating oil. When the movable mold shell 7 moves downward, the lower end of the push rod 15 is no longer in contact with the lower end of the movable mold shell 7. At this time, the piston plate 14 moves downward under the action of the second spring 16. The downward movement of the piston plate 14 exerts a certain pressure on the lubricating oil, thereby squeezing the lubricating oil into the interior of the liquid guide tube 13, then into the interior of the cavity 41, and then into the opening rod. The liquid is discharged from the inside of the 9 through the first liquid hole 21. This allows liquid to be released from the outside of the 9 during operation. When there is lubricating oil on the outside of the 9, the friction is less when the 9 is pulled out from the inside of the brick, and the brick will not be damaged by friction. It should be noted that the diameter of the first liquid hole 21 is small, so the material will not enter the first liquid hole 21 when the pressure block 5 presses the material. When the operation is finished, the moving mold shell 7 moves upward and the lower end contacts the lower end of the push rod 15, pushing the push rod 15 to drive the piston plate 14 to move upward.

[0044] like Figure 7 and Figure 8 As shown, a movable rod 22 is slidably connected inside the perforated rod 9. The outer side of the perforated rod 9 and the movable rod 22 are evenly provided with second liquid holes 23. The lower ends of both sides of the perforated rod 9 are fixedly connected with limit rods 24. The rod wall of the limit rod 24 is slidably connected to the lower end of the movable rod 22. The rod wall of the limit rod 24 is sleeved with a third spring 25. The third spring 25 provides an upward supporting force to the movable rod 22.

[0045] When the perforating rod 9 extends into the brick, the moving rod 22 remains stationary relative to the perforating rod 9 under the action of the third spring 25. At this time, the first liquid hole 21 and the second liquid hole 23 are misaligned, preventing the lubricating oil from flowing out. When the pressure block 5 moves down and contacts the upper end of the moving rod 22, it applies a certain pressure to the moving rod 22, causing the moving rod 22 to move downward relative to the perforating rod 9, compressing the third spring 25. This aligns the first liquid hole 21 with the second liquid hole 23, allowing the lubricating oil to be released. This prevents the lubricating oil from being discharged from the first liquid hole 21 when the lubricating oil is injected into the hose 11, avoiding excessive use and waste of lubricating oil.

[0046] like Figure 9 and Figure 10 As shown, a gear 34 is fixedly connected to the lower end of the rod wall of the perforated rod 9. The lower end of the perforated rod 9 is rotatably connected to the upper end of the horizontal plate 8. The perforated rod 9 rotates relative to the horizontal plate 8. A gear frame 35 is fixedly connected to the outer side of multiple gears 34. Rods 40 are fixedly connected to the front and rear positions of the gear frame 35. The rod wall of the rod 40 is slidably connected to the upper end of the horizontal plate 8. The rod 40 can move back and forth relative to the horizontal plate 8. A fourth spring 39 is sleeved on the rod wall of the rod 40. The fourth spring 39 enables the rod 40 to return to its original position after movement. A first spiral rod 36 is fixedly connected to the rear end of the inner wall of the movable mold shell 7. A spiral block 38 is rotatably connected to the rear end of the horizontal plate 8. The spiral block 38 can rotate relative to the horizontal plate 8. The spiral block 38 and the rod wall of the first spiral rod 36 are spirally driven. An eccentric wheel 37 is fixedly connected to the outer side of the spiral block 38. The rotation of the spiral block 38 drives the eccentric wheel 37 to rotate.

[0047] When the movable mold shell 7 moves, it drives the first spiral rod 36 to move. When the first spiral rod 36 moves, it causes the spiral block 38 to rotate. The rotation of the spiral block 38 drives the eccentric wheel 37 to rotate. The eccentric wheel 37 is in contact with the rear end of the gear frame 35. When the eccentric wheel 37 rotates, under the action of the fourth spring 39, it causes the gear frame 35 to move back and forth continuously. The back-and-forth movement of the gear frame 35 causes the gear 34 to rotate in both directions. The rotation of the gear 34 in both directions drives the perforating rod 9 to rotate in both directions. When pressing the brick, the rotation of the perforating rod 9 in both directions allows it to better penetrate into the interior of the brick. When demolding, the rotation of the perforating rod 9 in both directions allows it to better separate from the brick, thereby improving processing efficiency.

[0048] like Figure 6As shown, cylinders 30 are fixedly connected to both sides of the lower inner wall of the movable mold shell 7. When the movable mold shell 7 moves downward, it drives the cylinders 30 to move downward. The cylinders 30 and the horizontal plate 8 are slidably arranged. A one-way valve 32 is fixedly connected to the lower end of the cylinder 30. The one-way valve 32 is a prior art technology and allows gas to pass in one direction. A piston block 33 is slidably connected inside the cylinder 30. The piston block 33 can move up and down relative to the cylinder 30. An air pipe 31 is fixedly connected inside the piston block 33. A round block 26 is fixedly connected to both sides of the upper end of the movable mold shell 7. A block block 27 is provided at the upper end of the round block 26. A limiting block 28 is fixedly connected to the lower end of the block block 27. The limiting block 28 is used to limit the distance that the block block 27 moves upward. Air holes 29 are evenly opened at the upper end of the air pipe 31.

[0049] When the movable mold shell 7 moves downward, it drives the cylinder 30 downward. Since the upper end of the air pipe 31 is fixedly connected to the circular block 26, the air pipe 31 keeps the piston block 33 stationary. At this time, the piston block 33 moves upward relative to the cylinder 30. The one-way valve 32 is in the open state, allowing gas to enter the inside of the cylinder 30. When the movable mold shell 7 starts to move upward, the cylinder 30 moves upward. When the cylinder 30 moves upward, the piston block 33 compresses the gas inside the cylinder 30, which then enters the air pipe 31 and is ejected through the air hole 29, pushing the block 27 upward. This allows the gas to enter the upper end of the base 1, so that there is a certain amount of gas on the outside of the brick. This can prevent a vacuum state between the brick and the base 1 during demolding, thus creating negative pressure when removing the brick. By adding gas, it is easier to remove the brick.

[0050] like Figure 3 and Figure 4 As shown, a second spiral rod 10 is rotatably connected to both sides of the inner wall of the movable mold shell 7. The rod wall of the second spiral rod 10 is connected to the internal spiral drive of the horizontal plate 8. When the horizontal plate 8 moves up and down, the second spiral rod 10 rotates. A first circular plate 18 is fixedly connected to the lower end of the second spiral rod 10. The rotation of the second spiral rod 10 drives the first circular plate 18 to rotate. A circular rod 19 is uniformly slidably connected inside the first circular plate 18. The circular rod 19 can move upward relative to the first circular plate 18, and the rotation of the first circular plate 18 drives the circular rod 19 to move. A second circular plate 42 is fixedly connected to the upper end of the circular rod 19. A fifth spring 20 is fixedly connected to the lower end of the second circular plate 42. The fifth spring 20 provides upward support to the second circular plate 42. Friction blocks 43 are fixedly connected to both the upper end of the second circular plate 42 and the inside of the movable mold shell 7. The movement of the second circular plate 42 drives the friction blocks 43 to move.

[0051] When the movable mold shell 7 moves up and down, it drives the second spiral rod 10 to move. Under the action of the horizontal plate 8, the second spiral rod 10 rotates. The rotation of the second spiral rod 10 causes the fixedly connected first circular plate 18 to rotate. The rotation of the first circular plate 18 drives the circular rod 19 to move. The movement of the circular rod 19 drives the second circular plate 42 to rotate. The rotation of the second circular plate 42 drives the upper friction block 43 to rotate. Because the lower end of the second circular plate 42 is supported by the fifth spring 20, the lower friction block 43 rubs against the upper friction block 43, thus generating vibration. This gives the movable mold shell 7 a certain vibration effect. When adding raw materials into the base 1, it can help the raw materials spread out, making it easier for the pressing block 5 to press. At the same time, after pressing, the vibration can help the bricks separate from the upper end of the movable mold shell 7, thereby improving the brick removal effect.

[0052] Working principle: During operation, the raw material to be molded is placed on the inner wall of the base 1. Then, the hydraulic rod 3 is activated. The output end of the hydraulic rod 3 drives the pressing block 5 to move downward. The pressing block 5 moves downward to press the raw material. When the pressing block 5 begins to contact the raw material, the raw material and the moving mold shell 7 move downward. Since the perforating rod 9 is fixedly connected to the horizontal plate 8, it moves upward relative to the moving mold shell 7, thereby allowing the perforating rod 9 to extend into the interior of the raw material, thus creating a hollow space inside the brick. The moving mold shell 7 moves upward relative to the horizontal plate 8. When plate 8 moves downward, the first spring 17 is stretched. When the pressing work is finished, the output end of hydraulic rod 3 moves upward, and hydraulic rod 3 drives pressure block 5 to move upward. At this time, the upper end of the brick and the moving mold shell 7 is not under the pressure of pressure block 5. At this time, the moving mold shell 7 resets and moves upward under the action of the first spring 17, and has an upward pushing force on the brick. At this time, the opening rod 9 moves downward relative to the moving mold shell 7. The opening rod 9 retracts into the interior of the moving mold shell 7, so that the opening rod 9 can be pulled out from the interior of the brick, making it more convenient for workers to remove the brick.

[0053] Furthermore, in the initial state, the movable mold shell 7 is located at the upper end of the inner wall of the base 1. At this time, the piston plate 14 is at the upper end relative to the liquid shell 12, and the lower end of the piston plate 14 is filled with a certain amount of lubricating oil. When the movable mold shell 7 moves downward, the lower end of the push rod 15 no longer contacts the lower end of the movable mold shell 7. At this time, the piston plate 14 moves downward under the action of the second spring 16. The downward movement of the piston plate 14 exerts a certain pressure on the lubricating oil, thereby squeezing the lubricating oil into the interior of the liquid guide tube 13, then into the interior of the cavity 41, and then into the opening. The liquid inside the perforated rod 9 is discharged from the first liquid hole 21. This allows liquid to be released from the outside of the perforated rod 9 during operation. When there is lubricating oil on the outside of the perforated rod 9, the friction is reduced when the perforated rod 9 is pulled out from the inside of the brick, and the brick will not be damaged due to friction. It should be noted that the diameter of the first liquid hole 21 is small, so the material will not enter the first liquid hole 21 when the pressure block 5 presses the material. When the operation is finished, the moving mold shell 7 moves upward and the lower end contacts the lower end of the push rod 15, pushing the push rod 15 to drive the piston plate 14 to move upward.

[0054] Furthermore, when the perforating rod 9 extends into the brick, the moving rod 22 remains stationary relative to the perforating rod 9 under the action of the third spring 25. At this time, the first liquid hole 21 and the second liquid hole 23 are misaligned, preventing the lubricating oil from flowing out. When the pressure block 5 moves down and contacts the upper end of the moving rod 22, it applies a certain pressure to the moving rod 22, causing the moving rod 22 to move downward relative to the perforating rod 9 and compress the third spring 25. This aligns the first liquid hole 21 with the second liquid hole 23, allowing the lubricating oil to be released. This prevents the lubricating oil from being discharged from the first liquid hole 21 when the lubricating oil is injected into the hose 11, thus avoiding excessive use and waste of lubricating oil.

[0055] Furthermore, when the movable mold shell 7 moves, it drives the first spiral rod 36 to move. The movement of the first spiral rod 36 causes the spiral block 38 to rotate. The rotation of the spiral block 38 drives the eccentric wheel 37 to rotate. The eccentric wheel 37 engages with the rear end of the gear frame 35. As the eccentric wheel 37 rotates, under the action of the fourth spring 39, the gear frame 35 moves back and forth continuously. The reciprocating movement of the gear frame 35 causes the gear 34 to rotate in both directions. The rotation of the gear 34 in both directions drives the perforating rod 9 to rotate in both directions. When pressing the brick, the rotation of the perforating rod 9 allows it to better penetrate the interior of the brick. During demolding, the rotation of the perforating rod 9 in both directions allows it to better detach from the brick, thereby improving processing efficiency.

[0056] When the movable mold shell 7 moves downward, it drives the cylinder 30 to move downward. Since the upper end of the air pipe 31 is fixedly connected to the circular block 26, the air pipe 31 keeps the piston block 33 stationary. At this time, the piston block 33 moves upward relative to the cylinder 30. The one-way valve 32 is in the open state, allowing gas to enter the inside of the cylinder 30. When the movable mold shell 7 starts to move upward, the cylinder 30 moves upward. When the cylinder 30 moves upward, the piston block 33 compresses the gas inside the cylinder 30, which in turn allows the gas to enter the inside of the air pipe 31 and then be ejected through the air hole 29, pushing the block 27 upward, which in turn allows the gas to enter the upper end of the base 1, so that there is a certain amount of gas on the outside of the brick. In this way, when demolding, a vacuum state can be avoided between the brick and the base 1, so that there is negative pressure when removing the brick. By adding gas, it is easier to remove the brick.

[0057] Furthermore, when the movable mold shell 7 moves up and down, it drives the second spiral rod 10 to move. Under the action of the horizontal plate 8, the second spiral rod 10 rotates. The rotation of the second spiral rod 10 causes the fixedly connected first circular plate 18 to rotate. The rotation of the first circular plate 18 drives the circular rod 19 to move. The movement of the circular rod 19 drives the second circular plate 42 to rotate. The rotation of the second circular plate 42 drives the upper friction block 43 to rotate. Because the lower end of the second circular plate 42 is supported by the fifth spring 20, the lower friction block 43 rubs against the upper friction block 43, thereby generating vibration. This gives the movable mold shell 7 a certain vibration effect. When adding raw materials into the base 1, it can help the raw materials spread out, making it easier for the pressing block 5 to press. At the same time, after pressing, the vibration can help the bricks separate from the upper end of the movable mold shell 7, thereby improving the brick removal effect.
