Description

Technical Field

[0001] The invention relates to the field of building block production, and in particular to a rapid demoulding mechanism for producing self-insulating building blocks. Background Art

[0002] As is known, self-insulating blocks are a type of block material with insulation function, which is commonly used in building walls and can effectively improve the insulation performance of buildings. Such blocks usually have insulation materials added inside the material, such as polystyrene foam or rock wool, etc., to reduce heat conduction and improve the insulation effect of building walls.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] In the description of the present invention, it is necessary to understand that Figure 2 The first section 401 is above relative to the second section 402, and vice versa. Terms such as "center", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", and "circumferential" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0033] Reference Figure 1-8 A quick demoulding mechanism for producing self-insulating building blocks provided in an embodiment of the present invention comprises a mold 1 for holding building blocks, and the mold 1 is a split structure, and also comprises a frame 2, on which a clamping assembly for fixing the mold 1 and a lifting assembly for adjusting the vertical height of the clamping assembly are provided, and a fixing assembly is also provided on the frame 2; in the process of the clamping assembly clamping the mold 1, the clamping assembly synchronously drives the fixing assembly to move downward to fix the position of the building block.

[0034] Specifically, the frame 2 is a frame-type structure. In order to simplify the structure of the present application, the frame 2 is simplified into a square plate-shaped structure in the present application. The mold 1 is composed of a square cylindrical upper mold and a plate-shaped lower mold located below the upper mold, and the upper mold and the lower mold are connected by an existing clamping structure. The raw materials of the blocks are cast into the upper mold. When the blocks are formed (and in order to facilitate subsequent cutting, the blocks in this process are in an incompletely solidified state), the clamping structure on the mold 1 is opened, and the position of the formed blocks in the mold 1 is fixed by fixing components such as oil cylinders to prevent the blocks from moving up synchronously with the mold 1, thereby preventing the blocks from falling and being damaged, and then the blocks are clamped. The upper mold is clamped by clamping components such as plates, and the upper mold is lifted by lifting components such as chains, so that relative movement is generated between the upper mold and the block in the vertical direction, so that the mold 1 can be removed from above the block. This is a prior art and will not be repeated. One of the core innovations of the embodiment of the present invention is that a fixing component is arranged on the clamping component. The purpose of such a setting is that in the process of the clamping component clamping the mold 1, the clamping component simultaneously drives the fixing component to move downward to fix the position of the block, so that the block cannot be moved up synchronously with the mold 1, thereby eliminating the need for a separate lifting cylinder to fix the position of the block, thereby simplifying the demolding process.

[0035] Preferably, the lifting assembly includes a lifting plate 3, a plurality of vertical rods 4 are arranged on the frame 2, and the lifting plate 3 is slidably connected with the plurality of vertical rods 4 at the same time; the frame 2 is also provided with a first power member for driving the lifting plate 3 to move vertically. Specifically, there are four vertical rods 4, and the four vertical rods 4 are evenly arranged on the lower surface of the lifting plate 3. The lifting plate 3 is provided with four sliding holes, and the four vertical rods 4 are slidably connected with the four sliding holes to drive the lifting plate 3 to move vertically along the vertical rods 4. Since the clamping assembly is arranged on the lifting plate 3, the clamping assembly and the mold 1 can be driven to move vertically. The first power assembly can be an existing linear reciprocating drive assembly such as a hydraulic cylinder, which is used to provide the power required for the vertical lifting of the lifting plate 3.

[0036] Preferably, the clamping assembly includes a clamping jaw 5 and a connecting rod 6, one end of each of the two connecting rods 6 is rotationally connected to the clamping jaw 5, and the other end of each of the two connecting rods 6 is rotationally connected to the lifting plate 3; and also includes a second power member for driving the clamping jaw 5 to open and close. Preferably, there are four clamping jaws 5, and the four clamping jaws 5 are symmetrically arranged on both sides of the lifting plate 3 in pairs. For a single clamping jaw 5, there are two connecting rods 6, and the two connecting rods 6 have the same length and are arranged parallel to each other. The clamping jaw 5 is arranged vertically to the lifting plate 3 as a whole, and a groove body for the connecting rod 6 to rotate is provided on the lifting plate 3. One end of the two connecting rods 6 is rotationally connected to the lifting plate 3 at the same time, and the other end is rotationally connected to the clamping jaw 5 at the same time, so that a parallelogram is formed between the two connecting rods 6, the lifting plate 3 and the clamping jaw 5, that is, when one connecting rod 6 rotates relative to the lifting plate 3, the other connecting rod 6 and the clamping jaw 5 will rotate synchronously, so that the four are always connected. The final product is a parallelogram, and the second power member can be an existing driving structure such as a motor, so that a connecting rod 6 can be driven by the second power member to rotate on the lifting plate 3 to drive the clamping jaw 5 to approach or move away from the center position of the lifting plate 3, that is, the upper mold can be clamped by controlling the rotation of a single connecting rod 6, and a flange is provided at the top edge of the upper mold, and the clamping jaw 5 abuts against the lower surface of the flange, thereby preventing the clamping jaw 5 from separating from the upper mold, and the clamping jaw 5 will always be in a parallel state with the upper mold during the movement, so that the clamping jaw 5 can have a larger contact surface with the side wall of the upper mold, thereby improving the stability of clamping.

[0037] As an alternative solution for the above-mentioned multiple motors to drive the multiple clamps 5 to rotate respectively, preferably, the second power member includes a dual-axis motor 7 and two threaded rods 8 connected to the output end of the dual-axis motor 7, the dual-axis motor 7 is fixed to the lifting plate 3, and two driving blocks 9 are slidably arranged on the lifting plate 3, the two driving blocks 9 are respectively threadedly connected to the two threaded rods 8, and a rack 10 is arranged on the driving block 9, and a gear 11 is arranged on one of the connecting rods 6, and the gear 11 is meshed with the rack 10. Specifically, the dual-axis motor 7 is fixed to the upper surface of the lifting plate 3 through a base, and the dual-axis motor 7 has two output ends, which are respectively threadedly connected to the two threaded rods 8, and the threads on the two threaded rods 8 are in opposite directions. There are two driving blocks 9, and the two driving blocks 9 are symmetrically arranged on both sides of the dual-axis motor 7. Threaded holes matching the two threaded rods 8 are provided inside the two driving blocks 9. A sliding portion 12 is provided at the bottom of the driving block 9, and a sliding groove 13 matching the sliding portion 12 is provided on the lifting plate 3. The sliding portion 12 is slidably connected to the sliding groove 13. Two racks 10 are provided on a single driving block 9, and a gear 11 is fixed to the outer circumferential surface of the rotational connection position of one of the connecting rods 6 and the lifting plate 3. The purpose of such a setting is that when it is necessary to control the clamping assembly for clamping, the clamping claws 5 are moved down to the two sides of the upper mold (such as Figure 3As shown, it is in an unclamped state), then the dual-axis motor 7 is started, and the dual-axis motor 7 drives the two threaded rods 8 at its output end to rotate. Since the threads on the two threaded rods 8 are in opposite directions, the two driving blocks 9 are driven to move in a direction away from the center position of the lifting plate 3, thereby driving multiple racks 10 to move horizontally. Since the gear 11 is engaged with the rack 10, the multiple gears 11 and the connecting rod 6 are driven to rotate synchronously, and the multiple clamps 5 are driven to rotate at the same time, so that the upper mold can be clamped quickly. On the contrary, when the upper mold needs to be lowered, the output end of the dual-axis motor 7 is controlled to rotate in the opposite direction, thereby driving the two driving blocks 9 to move in a direction close to the center position of the lifting plate 3 at the same time, thereby driving the rack 10 to move in the opposite direction, and driving the gear 11 to rotate in the opposite direction to release the clamping effect of the clamp 5 on the upper mold.

[0038] As an alternative to the above-mentioned cylinder fixing the position of the forming block, preferably, the fixing assembly includes a pressure plate 14, the vertical rod 4 includes a first section 401 and a second section 402 which are slidably connected to each other, and a first spring 15 is arranged between the first section 401 and the second section 402, the pressure plate 14 is fixedly connected to the second section 402, a transmission block 16 is arranged on the lifting plate 3, the transmission block 16 is located on the movement stroke of the driving block 9, and a check assembly is arranged between the first section 401 and the second section 402 for preventing the second section 402 from moving in the opposite direction. Specifically, the first section 401 is located above the second section 402, and a telescopic groove adapted to the second section 402 is opened inside the first section 401. The second section 402 is slidably connected to the telescopic groove, and a limiting structure (not shown in the figure) is arranged between the two to prevent the two from rotating and disengaging from each other. One end of the first spring 15 is fixed to the inner top wall of the telescopic groove, and the other end is fixed to the top of the second section 402. The elastic force of the first spring 15 makes the pressure plate 14 located above the upper mold, and the top of the first section 401 is fixed to the lower surface of the frame 2, and the pressure plate 14 is fixed to the bottom end of the second section 402. A wedge surface is arranged at the bottom edge position of the sliding part 12, and the transmission block 16 is fixed to the upper surface of the lifting plate 3, and the cross-section of the transmission block 16 is a right-angled trapezoid. The inclined surface of the transmission block 16 is located on the movement stroke of the wedge surface of the sliding part 12. The non-return component can be a locking structure such as a latch. The purpose of such a setting is that before clamping the upper mold, The clamping jaws 5 are located on both sides of the upper mold, and the pressure plate 14 is located above the upper mold. When the upper mold needs to be clamped, the dual-axis motor 7 is started, thereby driving the driving block 9 to move horizontally and driving the sliding portion 12 to move synchronously. When the wedge surface of the sliding portion 12 abuts against the inclined surface of the transmission block 16, it will drive the transmission block 16 and the pressure plate 14 to move downward, and store force on the first spring 15, so that the pressure plate 14 abuts against the surface of the block, and under the action of the non-return assembly, the second section 402 and the pressure plate 14 can be kept at the vertical height and cannot move up to limit the position of the block, so that when the clamping assembly drives the upper mold to move up, the pressure plate 14 can block the position of the block to prevent the block from moving up synchronously with the upper mold. When the upper mold is away from the block, the clamping assembly is released, so that the mold 1 can be put down, and at the same time, the action of the non-return assembly is released, and the pressure plate 14 and the second section 402 are automatically reset under the action of the elastic force of the first spring 15.

[0039] Furthermore, a buffer pad 17 is provided on the pressing plate 14. Specifically, the buffer pad 17 is made of a soft material such as rubber, and has the ability to self-reset after being deformed by force. During the downward movement of the pressing plate 14, the buffer pad 17 plays a buffering role, so that the pressing plate 14 and the blocks can be prevented from being over-extruded, so as to prevent the blocks from being crushed.

[0040] As an alternative to the above-mentioned pin fixing the first section 401 and the vertical position of the pressure plate 14, preferably, the non-return assembly includes a clamping plate 18 arranged on the second section 402, a blocking rod 19 is slidably arranged on the first section 401, a third spring 28 is arranged between the blocking rod 19 and the first section 401, and the blocking rod 19 is clamped with the clamping plate 18. Specifically, the card plate 18 is arranged vertically on the outer peripheral surface of the second section 402 and close to the top of the second section 402. The cross-section of the teeth on the card plate 18 is a right triangle, and the inclined surface of the teeth is located at the bottom. There are four blocking rods 19 and they are arranged along the radial direction of the first section 401 respectively. A wedge-shaped surface is provided on one end of the blocking rod 19 close to the card plate 18, and the end is engaged with one of the teeth of the card plate 18. A protrusion is provided on the blocking rod 19. The third spring 28 is provided between the protrusion and the outer peripheral surface of the first section 401. The elastic force of the third spring 28 makes the blocking rod 19 inserted into the card plate 18. The effect of such a setting is that when the second power member drives the pressure plate 14 to move downward, the card plate 18 will move downward relative to the blocking rod 19 and accumulate force on the first spring 15, so that the inclined surface of one of the teeth of the card plate 18 abuts against the wedge surface of the blocking rod 19 and pushes the blocking rod 19. The blocking rod 19 rotates in the direction away from the card plate 18 to avoid it and accumulates force on the third spring 28. When the blocking rod 19 is in contact with the tooth, the elastic force of the third spring 28 is released, so that the blocking rod 19 slides in the opposite direction and contacts with the upper surface of another tooth, and the surface is a horizontal surface, so that the card plate 18 cannot move up relative to the blocking rod 19, and the second section 402 cannot move upward relative to the first section 401 to achieve the anti-return effect. In this way, when the lifting assembly drives the lifting plate 3 and the mold 1 to move upward, the pressing plate 14 is always in a position abutting against the upper surface of the block under the action of the non-return assembly. When demolding is completed, the blocking rod 19 can be controlled to slide in the direction away from the card plate 18 by structures such as an electric push rod, thereby releasing the clamping effect of the blocking rod 19 and the card plate 18. At this time, the second section 402 is automatically reset under the action of the first spring 15.

[0041] As an alternative solution for the electric push rod to drive the blocking rod 19 away from the card plate 18 to achieve unlocking, preferably, the frame 2 is provided with an abutment plate 20, and the blocking rod 19 is provided with a first unlocking portion 21, the first unlocking portion 21 is located on the movement stroke of the abutment plate 20, and the abutment plate 20 is located on the movement stroke of the driving block 9. Specifically, the first unlocking portion 21 is a wedge-shaped structure extending downward from the blocking rod 19, the abutment plate 20 is a square plate, which is vertically slidably arranged on the frame 2 and is located below the first unlocking portion 21, and the abutment plate 20 is provided with wedge-shaped second unlocking portions 29 at both ends close to the first unlocking portion 21, and the four first unlocking portions 21 are respectively located on the movement strokes of the four second unlocking portions 29. The effect of such a setting is that when the lifting assembly drives the lifting plate 3 to move upward to lift the upper mold, it will drive the driving block 9 to move upward synchronously, and when the driving block 9 abuts against the abutment plate 20, it will drive the abutment plate 20 to move upward synchronously, and when the second unlocking portion 29 abuts against the first unlocking portion 21 abuts, it will drive the blocking rod 19 to slide in the direction away from the card plate 18 and accumulate force in the third spring 28. When the blocking rod 19 is away from the card plate 18, the elastic force of the first spring 15 is released, thereby realizing the passive reset of the second section 402 and the pressure plate 14. When the lifting plate 3 descends, the driving block 9 and the abutment plate 20 are away from each other, and the abutment plate 20 moves downward under the action of its own gravity and the elastic force of the third spring 28. When the second unlocking part 29 is away from the first unlocking part 21, the blocking rod 19 slides in the direction of the card plate 18 under the action of the elastic force of the third spring 28, so as to realize the passive reset of the blocking rod 19.

[0042] After the upper mold is separated from the block, some block residues will adhere to its inner wall, which will affect the quality of the block after molding when the next block raw material is cast. Furthermore, a cleaning mechanism is provided on the pressing plate 14, and the cleaning mechanism is used to remove the residues attached to the inner wall of the mold 1. Specifically, the cleaning mechanism can be a high-pressure spray gun or other structure. When the upper mold is separated from the block, the cleaning mechanism is started, which can remove the block residues attached to the inside of the upper mold to improve the quality of the block molding.

[0043] As an alternative to the above-mentioned active residue cleaning by the high-pressure spray gun, in another embodiment of the present invention, a scraper 22 is used to passively clean the inner wall of the upper mold. In order to facilitate the pressure plate 14 to drive the scraper 22 to smoothly enter the interior of the upper mold, the sum of the horizontal area of ​​the pressure plate 14 plus the horizontal area of ​​the scraper 22 is smaller than the internal area of ​​the upper mold. However, this method will result in a gap between the scraper 22 and the interior of the upper mold, so that the scraper 22 can only scrape off large residues on the inner wall of the mold 1, and smaller residues will pass through the gap, making it impossible to clean the small-sized residues. Preferably, the cleaning mechanism includes a scraper 22, which is elastically arranged on the pressure plate 14, and an abutment rod 23 is arranged on the first section 401, and an abutment block 24 is arranged on the scraper 22, and the abutment rod 23 is located on the movement stroke of the abutment block 24. Specifically, there are four scrapers 22, which are arranged on the four sides of the pressing plate 14 respectively. The sum of the horizontal area of ​​the pressing plate 14 and the horizontal area of ​​the scrapers 22 is smaller than the internal area of ​​the upper mold, and the upper and lower surfaces of the scrapers 22 are provided with cutting edges, that is, the cross section of the scrapers 22 is approximately trapezoidal. When the buffer pad 17 abuts against the upper surface of the block, the cutting edge of the scraper 22 is located inside the upper mold. For the two first sections 401 on one side, the abutment rod 23 penetrates the second section 402 and extends to the inside of the pressing plate 14 and the buffer pad 17. The bottom end of the abutment rod 23 is provided with two horizontal parts, and the two horizontal parts are arranged perpendicular to each other, that is, the two horizontal parts are arranged corresponding to the abutment blocks 24 on the two adjacent surfaces, and in order to facilitate abutment, the ends of the horizontal parts are arc-shaped, and a mounting groove 25 is provided inside the pressure plate 14. The abutment block 24 is horizontally slidably arranged inside the mounting groove 25, and a wedge-shaped surface is provided on the abutment block 24, and the arc surface of the abutment rod 23 is located on the movement stroke of the wedge-shaped surface of the abutment block 24. The elastic setting, that is, a second abutment block 24 and the mounting groove 25 are provided. The spring 26 is set in this way. When the pressure plate 14 drives the scraper 22 to move downward, the sum of the horizontal area of ​​the pressure plate 14 and the horizontal area of ​​the scraper 22 is smaller than the internal area of ​​the upper mold, so that the pressure plate 14 and the scraper 22 can be synchronously and smoothly entered into the upper mold, and in this process, the wedge surface of the abutment block 24 will abut against the wedge surface of the abutment rod 23, so that the abutment block 24 and the scraper 22 are passively moved in a direction away from the center line of the pressure plate 14, so as to drive the four scrapers 22 to contact the upper mold respectively. The four inner walls abut against each other and store force on the second spring 26, so that there is no gap between the scraper 22 and the inside of the upper mold. When the upper mold moves relative to the scraper 22, the scraper 22 can scrape off both small-sized and large-sized residues attached to the inner wall of the upper mold. When the scraper 22 is used up, the second section 402 moves up and resets under the action of the first spring 15, which will make the arc surface of the abutment block 24 and the abutment rod 23. At this time, the abutment block 24 and the scraper 22 automatically reset under the action of the elastic force of the second spring 26 to prepare for the next cleaning.

[0044] It should be noted that when the lifting assembly drives the upper mold to move upward to achieve demoulding, the cutting blade below the scraper 22 will scrape and clean the upper mold, and when the lifting assembly drives the upper mold to move downward to remove the upper mold from the clamping assembly, the cutting blade above the scraper 22 will scrape and clean the inner wall of the upper mold. In this way, the inner wall of the upper mold can be cleaned multiple times during the entire demoulding process.

[0045] In the process of multiple scrapers 22 moving toward the inner wall of the upper mold at the same time, since the length of the scraper 22 is smaller than the length of a single side of the upper mold, when the multiple scrapers 22 are in contact with the multiple inner walls of the upper mold, there will be gaps between the ends of adjacent scrapers 22. The gap creates a cleaning dead corner on the inner wall of the upper mold, making it impossible to completely remove the residues at the corner of the inner wall of the upper mold. Furthermore, the scraper 22 includes a third section 2201 and a fourth section 2202 that are slidably connected to each other, and an elastic sheet 27 is provided between the fourth section 2202 and the abutment block 24. Specifically, for a single scraper 22, it includes a third section 2201 and two fourth sections 2202, the two fourth sections 2202 are symmetrically and slidably arranged at the two ends of the third section 2201, and when the scraper 22 is in contact with the inner wall of the mold 1, the sliding part of the fourth section 2202 and the third section 2201 is also in contact with the inner wall of the mold 1, the abutment block 24 and the scraper 22 are slidably connected, and the elastic sheet 27 is preferably an arc-shaped elastic metal sheet, which has the ability to automatically recover after deformation, one end of the elastic sheet 27 is fixed to the side of the abutment block 24, and the other end is fixed to the side of the fourth section 2202, and the elastic force of the elastic sheet 27 makes the abutment block 24 and the scraper 22 have a tendency to move away from each other. The effect of such a setting is that when the abutment block 24 and the abutment rod are in contact, When the abutment block 24 abuts against the abutment rod 23, it will drive the abutment block 24 and the scraper 22 to move synchronously in the direction away from the center line of the pressure plate 14. After the scraper 22 abuts against the inner wall of the upper mold, the scraper 22 cannot continue to move. In the process of the abutment block 24 and the abutment rod 23 continuing to abut, the abutment block 24 will slide in the direction of the scraper 22. In this process, the benefits brought by the elastic sheet 27 are: first, the abutment block 24 will squeeze the elastic sheet 27 to achieve buffering, avoiding excessive squeezing of the scraper 22 and the inner wall of the upper mold, thereby preventing damage to the scraper 22; second, after being squeezed, the elastic sheet 27 will be deformed, thereby pushing the fourth section 2202 in the direction away from the third section 2201, thereby filling the gap between the ends of adjacent scrapers 22 to reduce cleaning dead angles, thereby improving the cleaning effect of the upper mold.
