Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a molding die for autoclaved aerated concrete blocks. Background Technology

[0002] A molding die is a specialized tool used to shape the raw materials of autoclaved aerated concrete (AAC) blocks according to a pre-set shape and size. It has a fixed cavity and a pressure-bearing structure to ensure the raw materials maintain a regular shape during the pouring and curing stages. After mixing, the raw materials are poured into the molding die, which restricts their flow and imparts their initial shape. After curing to form a green body, the die is removed, and the green body enters the autoclaving process to finally become the blocks. The precision of the die directly determines the dimensional tolerances and surface flatness of the blocks, and its structural design also affects demolding efficiency and the block production qualification rate.

[0003] In existing technologies, some autoclaved aerated concrete (AAC) block molding molds mainly consist of a mold shell and an oil film layer. A release agent is evenly applied to the surface of the oil film layer to enhance the anti-sticking effect. Then, the well-mixed AAC raw material is poured into the cavity of the mold shell. The raw material maintains a preset shape under the constraint of the mold shell. After that, the mold is left to stand until the raw material initially solidifies to form a blank. The oil film layer can reduce the adhesion between the blank and the mold shell. Finally, the blank is separated from the mold shell by a demolding mechanism, completing the molding of the block blank and preparing for the subsequent autoclaving process.

[0004] In the existing technology, some autoclaved aerated concrete (AAC) block molding molds only use a static mold setting method for raw material foaming. During the initial solidification process of the raw material to form a green body, the foaming of the raw material is difficult to be complete, which seriously affects the molding effect of the block green body. To address this issue, an autoclaved aerated concrete (AAC) block molding mold is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mold for forming autoclaved aerated concrete blocks, which aims to improve the problem that the raw materials of some autoclaved aerated concrete block molding molds are difficult to fully foam when left to stand.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A mold for forming autoclaved aerated concrete blocks includes a mold shell, an oil film layer fixedly connected to the inner and outer sides of the mold shell, a secondary ejection mechanism provided inside the mold shell, a liftable base plate fixedly connected to the bottom of the oil film layer, and two vibration mechanisms provided at the bottom of the liftable base plate. The vibration mechanism includes a support plate b, the top of which is slidably connected to the bottom of the liftable base plate. A connecting block b is fixedly connected to the bottom of the support plate b. Two springs are fixedly connected to the outer sides of each connecting block b. A connecting block a is fixedly connected to the bottom of each spring. A limit plate is fixedly connected to the bottom of every two connecting blocks a. A power component is fixedly connected to the top of the limit plate. A bearing is fixedly connected to the outer right side of the power component. A vibration component is provided on the outside of the bearing. A rotating wheel is fixedly connected to the outer right side of the bearing. As a further description of the above technical solution: The secondary ejection mechanism includes multiple support rods, the bottom of which is fixedly connected to the inner bottom side of the mold shell. A locking block is slidably connected to the outer side of each support rod, and a support rod is slidably connected to the outer side of the locking block away from the support rod. Two drive assemblies are fixedly connected to the bottom of the multiple support rods, and a clamping plate is fixedly connected to the outer side of the limiting plate. As a further description of the above technical solution: The two power components include two support plates a, the bottom of the support plate a is fixedly connected to the top of the limiting plate, a fixing plate is fixedly connected to the outer left side of the support plate a, a motor is fixedly connected to the outer left side of the fixing plate, and the motor drive end is fixedly connected to the outer left side of the bearing. As a further description of the above technical solution: The shaking component includes an eccentric column, the outer right side of which is fixedly connected to the outer left side of the rotating wheel, and a cylindrical sleeve is rotatably connected to the outer side of the eccentric column. As a further description of the above technical solution: The drive assembly includes a connecting plate, the top of which is fixedly connected to the bottom of a plurality of support rods, and the bottom of which is fixedly connected to an electric telescopic rod. As a further description of the above technical solution: Multiple support columns are slidably connected to the bottom of the two support plates b, and the bottoms of the multiple support columns are fixedly connected to the top of the limiting plate; As a further description of the above technical solution: The external parts of the plurality of support rods are slidably connected to the inside of the clamping plate, and the external parts of the plurality of support rods are slidably connected to the inside of the clamping plate; As a further description of the above technical solution: The external sliding connections of the plurality of the card blocks are made inside the clamping plate, and the external sliding connections of the plurality of the card blocks are made on both sides of the limiting plate.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the bearing to start rotating, and the rotation of the bearing drives the rotating wheel to rotate. As the rotating wheel rotates, the eccentric column rotates accordingly. Under the action of the eccentric column, the cylindrical sleeve vibrates up and down. The springs on both sides of the connecting block b are connected to the connecting block a to prevent the connecting block b from vibrating too violently. The connecting block b drives the support plate b to vibrate up and down continuously. The up and down vibration of the support plate b pushes the liftable base plate to vibrate up and down in the mold shell, thereby promoting the foaming process of concrete in the mold shell, accelerating the foaming speed, reducing the settling time, and making the foaming more complete.

[0008] 2. In this utility model, the connecting plate moves upward under the drive of the electric telescopic rod, causing multiple support rods on the connecting plate to move upward. The support rods push the locking block and drive the two clamping plates to move upward. To prevent the locking block from shifting during the movement, a limiting plate is provided inside the clamping plate to restrict the locking block from moving to both sides. After the support rod rises, the locking block is locked in the recess of the support rod, and neither the locking block nor the clamping plate rises further. The long support rod continues to rise under the drive of the drive assembly until the concrete on the liftable base plate is completely pushed out of the mold shell. This solves the problem that some equipment cannot push the concrete out of the mold by itself, reduces the damage to the concrete during the concrete removal process, and improves the integrity of the concrete.

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3 This utility model provides an embodiment of an autoclaved aerated concrete (AAC) block molding mold, comprising a mold shell 1, which serves as the main frame of the mold, forming the outer contour of the block molding and defining the cavity space for raw material pouring. An oil film layer 2 is fixedly connected to the inner and outer sides of the mold shell 1. The oil film layer 2 adheres to the inner wall of the mold shell 1, serving to isolate the raw material from the mold shell, reducing adhesion between the blank and the shell, and simultaneously improving the surface flatness of the blank for easy demolding. A secondary ejection mechanism 4 is provided inside the mold shell 1. A liftable base plate 3 is fixedly connected to the bottom of the oil film layer 2. The liftable base plate 3 serves as the bottom support of the cavity and can be moved up and down to adjust the cavity height to adapt to the molding requirements of blocks of different thicknesses. Two vibration mechanisms 5 are provided at the bottom of the liftable base plate 3. The vibration mechanism 5 includes a support plate b59, which serves as the connecting carrier between the liftable base plate 3 and the components below. The top of the support plate b59 is slidably connected to the liftable base plate 3 and can move slightly synchronously with vibration. The top of the support plate b59 is slidably connected to the bottom of the liftable base plate 3. A connecting block b56 is fixedly connected to the bottom of the support plate b59. The connecting block b56 connects the support plate b59 to the spring 57 and transmits the elastic force of the spring 57 to the support plate b59. Two springs 57 are fixedly connected to the outer sides of each connecting block b56. The springs 57 provide elastic support and play a buffering and shock-absorbing role during vibration, reducing the damage to components caused by excessive vibration. A connecting block a55 is fixedly connected to the bottom of the spring 57. The connecting block a55 connects the spring 57 to the limiting plate 51 and fixes the spring 57 to the limiting plate 51. A limiting plate 51 is fixedly connected to the bottom of every two connecting blocks a55. The limiting plate 51 is the basic fixing component of the vibration mechanism 5 and limits the installation position of each component. A power component 52 is fixedly connected to the top of the limiting plate 51. The two power components 52 include two support plates a521, which are fixed to the limiting plate 51, providing mounting support for the fixing plate 523 and the motor 522, ensuring the structural stability of the power component 52. The bottom of the support plate a521 is fixedly connected to the top of the limiting plate 51. The fixing plate 523 is fixedly connected to the outer left side of the support plate a521, fixing the position of the motor 522 and preventing displacement during operation. The motor 522 is fixedly connected to the outer left side of the fixing plate 523. The motor 522 is the core component of the power component 52, outputting rotational power after being powered on, driving the subsequent components to vibrate. The drive end of the motor 522 is fixedly connected to the outer left side of the bearing 54. The bearing 54 is fixedly connected to the outer right side of the power component 52, reducing frictional resistance during rotation, ensuring smooth rotation of the eccentric column 532 and the wheel 58, and transmitting the rotational power of the motor 522. A vibration component 53 is provided on the outside of the bearing 54. The vibration component 53 includes an eccentric column 532. The eccentric design of the eccentric column 532 generates centrifugal force when it rotates, causing the cylindrical sleeve 531 to reciprocate up and down, thereby generating vibration. The outer right side of the eccentric column 532 is fixedly connected to the outer left side of the rotating wheel 58. The cylindrical sleeve 531 is rotatably connected to the outside of the eccentric column 532. The cylindrical sleeve 531 is fitted on the outside of the eccentric column 532, converting the rotational centrifugal force of the eccentric column 532 into vertical linear motion, which drives the support plate b59 and the liftable base plate 3 to vibrate. The outer right side of the bearing 54 is fixedly connected to the rotating wheel 58. The rotating wheel 58 cooperates with the eccentric column 532 to increase the force-bearing area of ​​the rotating component, improve rotational stability, and ensure uniform transmission of vibration force. Multiple support columns 6 are slidably connected to the bottom of the two support plates b59. The support columns 6 vertically support the support plates b59, restricting their horizontal displacement, while allowing the support plates b59 to vibrate up and down, ensuring stable vibration direction. The bottom of the multiple support columns 6 is fixedly connected to the top of the limiting plate 51.

[0013] Reference Figures 2 to 4The secondary ejection mechanism 4 includes multiple support rods 41, which are the basic support components of the ejection mechanism. They are fixed to the bottom of the mold shell 1, limiting the movement trajectory of the locking block 42 and the support rod 43 to ensure accurate ejection. The bottoms of the multiple support rods 41 are fixedly connected to the inner bottom side of the mold shell 1. A locking block 42 is slidably connected to the outer side of each support rod 41. The locking block 42 connects and supports the support rods 41 and 43. A support rod 43 is slidably connected to the outer side of the locking block 42 away from the support rod 41. The support rod 43 transmits the pushing force of the drive assembly 45, pushing the liftable base plate 3 and the blank in stages to achieve secondary ejection. Two drive assemblies 45 are fixedly connected to the bottoms of the multiple support rods 43. The drive assembly 45 includes a connecting plate 452, which connects the multiple support rods 43 to the electric telescopic rod 451, enabling multiple... The support rods 43 move synchronously to ensure uniform transmission of the pushing force. The top of the connecting plate 452 is fixedly connected to the bottom of the multiple support rods 43. The bottom of the connecting plate 452 is fixedly connected to an electric telescopic rod 451. The electric telescopic rod 451 drives the power component of the drive assembly 45. After being powered on, it can extend and retract. The connecting plate 452 drives the support rods 43 to move up and down to realize the ejection action. The limiting plate 51 is fixedly connected to a clamping plate 44. The clamping plate 44 fixes the position of the support rods 41, support rods 43, and locking blocks 42, restricting their horizontal displacement and ensuring that the movement trajectory of each component is accurate during the ejection process. The external parts of the multiple support rods 43 are slidably connected to the inside of the clamping plate 44. The external parts of the multiple support rods 41 are slidably connected to the inside of the clamping plate 44. The external parts of the multiple locking blocks 42 are slidably connected to the inside of the clamping plate 44. The external parts of the multiple locking blocks 42 are slidably connected to the two sides of the outside of the limiting plate 51.

[0014] Working principle: First, an oil film layer 2 is applied to the inside of the mold shell 1. Steam-aerated concrete is added to the mold shell 1 until it covers the entire mold. Then, the steam-aerated concrete in the mold is foamed and allowed to stand. The motor 522 on the support plate a521 is started, causing the drive end of the motor 522 to drive the bearing 54 to rotate. The rotation of the bearing 54 drives the rotating wheel 58 to rotate. As the rotating wheel 58 rotates, the eccentric column 532 also rotates. Under the continuous rotation of the eccentric column 532, the cylindrical sleeve 531... The cylindrical sleeve 531 vibrates up and down, and the connecting block b56 connected to the vibrating component 53 also vibrates up and down along with the cylindrical sleeve 531. The springs 57 on both sides of the connecting block b56 are connected to the connecting block a55 to prevent the connecting block b56 from vibrating too violently. The connecting block b56 drives the support plate b59 to vibrate up and down continuously. The up and down vibration of the support plate b59 pushes the liftable base plate 3 to vibrate up and down in the mold shell 1. Multiple support columns 6 are used to support the liftable base plate 3, promote the foaming process of concrete in the mold shell 1, and accelerate the foaming speed.

[0015] Secondly, after foaming is completed, the two electric telescopic rods 451 are activated, causing the drive ends of the electric telescopic rods 451 to push the connecting plate 452 upward, so that the connecting plate 452 moves upward within the mold shell 1. This causes the multiple support rods 43 on the connecting plate 452 to move upward. The support rods 43 push the locking block 42 upward, which in turn drives the two clamping plates 44 to move upward. Subsequently, when the locking block 42 in the clamping plate 44 moves to the concave and convex parts of the support rod 41, in order to prevent the locking block 42 from shifting during the movement, a limiting plate 51 is provided inside the clamping plate 44 to restrict the locking block 42 from moving to both sides. This allows the locking block 42 to move towards the concave part of the support rod 43 as the support rod 43 continues to rise. After the support rod 43 rises, the locking block 42 is locked in the concave part of the support rod 43. At this time, neither the locking block 42 nor the clamping plate 44 rises. The support rod 41 continues to rise under the drive of the drive assembly 45 until the concrete on the liftable base plate 3 is completely pushed out of the mold shell 1.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
