Abstract
Description
Technical Field
[0001] This invention relates to the field of energy-saving building material production equipment technology, and in particular to an energy-saving production mold for ceramsite concrete precast wall panels. Background Technology
[0002] Precast wall panels are increasingly widely used in the construction industry due to their advantages such as convenient construction, high production efficiency, and controllable quality. Especially in the field of prefabricated buildings, ceramsite concrete precast wall panels are a new type of wall material with excellent lightweight, thermal insulation, and sound insulation properties, and their production and manufacturing technology is constantly developing and improving.
[0003] In the traditional production process of ceramsite concrete precast wall panels, steel molds are commonly used for concrete pouring and curing. During the curing stage, the concrete inside the mold is usually heated to accelerate its setting and strength gain. However, because traditional molds are typically single-layered and sealed, heating methods are often limited to heating the outer wall of the mold or indirect heating via steam entering the mold cavity. Uneven temperature distribution inside the concrete and in areas of different thicknesses can easily lead to defects such as cracking and warping in the precast wall panels during setting due to internal stress concentration, affecting product quality and service life. Furthermore, after the concrete has hardened, it often adheres tightly to the inner wall of the mold, requiring significant external force for demolding, which can easily damage the wall panel surface or the mold. Moreover, existing molds usually require disassembling the mold side panels during demolding, which is cumbersome, time-consuming, labor-intensive, and inefficient, increasing production costs. Summary of the Invention
[0004] The technical problem to be solved by this invention is that the existing production molds for ceramsite concrete precast wall panels have the disadvantages of uneven heating, high energy consumption, difficulty in demolding, and cumbersome operation. To this end, we propose an energy-saving production mold for ceramsite concrete precast wall panels.
[0005] To achieve the above objectives, this application adopts the following technical solution: an energy-saving production mold for ceramsite concrete precast wall panels, including a main mold, a pull-out movable left template provided on the left side of the main mold, a bottom template fixedly provided at the bottom of the main mold, a right template fixedly provided on the right side of the main mold, a front template fixedly provided at the front of the main mold, and a rear template fixedly provided at the rear of the main mold. The bottom template, right template, front template, and rear template are fixedly connected by high-strength bolts to form a closed mold cavity. A pouring port communicating with the mold cavity is opened on the upper part of the rear template.
[0006] The movable left template has a first core mold tube, a second core mold tube, and a third core mold tube horizontally running through it from top to bottom. The first, second, and third core mold tubes are all sealed to the movable left template, and their right ends horizontally penetrate the right template and seal to it when the movable left template is assembled with the main mold. The left ends of the first, second, and third core mold tubes are all fixedly connected to the same core mold connecting plate via flanges.
[0007] A tension threaded tube is provided on the right side of the right template, corresponding to the position of the second core mold tube. The left end of the tension threaded tube is connected to the right end of the second core mold tube by a threaded connection.
[0008] A right beam is fixedly connected to the right side of the right template. A first jack and a second jack are fixedly connected to the left side of the right beam, corresponding to the positions of the first core mold tube and the third core mold tube, respectively. The axis of the first jack is collinear with the axis of the first core mold tube, and the axis of the second jack is collinear with the axis of the third core mold tube.
[0009] The third and fourth jacks are fixedly connected to the core mold connecting plate on the left side of the movable left template. The output ends of the third and fourth jacks are both in contact with the side of the core mold connecting plate closest to the movable left template.
[0010] Furthermore, the first, second, and third core mold tubes are all hollow tubular structures with openings at both ends, forming a through channel inside. The vertical distances from the first core mold tube to the upper opening of the main mold, the vertical distances from the third core mold tube to the bottom template, the vertical distances between the first and second core mold tubes, and the vertical distances between the second and third core mold tubes are all equal, which is used to prevent cracking of the precast wall panels due to uneven heating during the curing process.
[0011] Furthermore, the tensioned threaded tube is an internally continuous tubular structure, with a disc-shaped rotating seat integrally formed at its right end. The side of the rotating seat closest to the right template is in close contact with the right side wall of the right template. A rotating rod is vertically inserted through the rotating seat along its radial direction, and the rotating rod is movably connected to the rotating seat.
[0012] Furthermore, the front and rear edges of the movable left template are each evenly distributed with one or more sets of fixing pins in the vertical direction. The fixing pins are vertically fixed to the movable left template and their axes are parallel to the axes of the first core mold tube, the second core mold tube, and the third core mold tube. The left side of the front template and the rear template are provided with matching first pin holes corresponding to the fixing pin positions. The fixing pins are inserted into the first pin holes to achieve the positioning and fixing of the movable left template with the front template and the rear template.
[0013] Furthermore, the outer walls of both the front and rear templates are welded with crisscrossing reinforcing ribs, which are vertically and fixedly connected to the outer walls of the corresponding templates.
[0014] Furthermore, a bidirectional threaded rod is horizontally inserted through the second core mold tube and is coaxial with it. The bidirectional threaded rod is rotatably connected to the second core mold tube through several bearing retainers spaced apart along its axial direction. One end of the bidirectional threaded rod protrudes from the end of the second core mold tube and is fixedly connected to a handwheel. Two sets of threaded segments with opposite directions are symmetrically arranged on its rod body. A first nut and a second nut are symmetrically fitted on the two sets of opposite threaded segments of the bidirectional threaded rod, and the first nut and the second nut are threadedly engaged with the corresponding threaded segments.
[0015] A first connecting rod is rotatably connected to the first nut, and a round-headed pin is rotatably connected to the end of the first connecting rod away from the first nut; a second connecting rod is rotatably connected to the second nut, and the end of the second connecting rod away from the second nut is rotatably connected to the round-headed pin; a second pin hole is opened on the wall of the second core mold tube corresponding to the position of the round-headed pin, and the round-headed pin extends and retracts along the second pin hole and its end extends out of the outer wall of the second core mold tube.
[0016] Furthermore, both the output ends of the first and second jacks are fixedly connected to tube end blocks, with the side of the tube end block away from the jack abutting against the end of the corresponding core mold tube.
[0017] Furthermore, the inner wall of the main mold, the right side wall of the movable left template, and the outer walls of the first core mold tube, the second core mold tube, and the third core mold tube are all coated with a polymer release coating, which is a polytetrafluoroethylene coating or a silicone rubber coating.
[0018] Furthermore, the drive rods of the first jack and the second jack are fixedly connected by a first coordinating rod. The first coordinating rod is arranged vertically, and its two ends are respectively fixedly connected to the ends of the drive rods of the first jack and the second jack.
[0019] Furthermore, the drive rods of the third and fourth jacks are fixedly connected by a second coordinating rod, which is set vertically and whose two ends are respectively fixedly connected to the ends of the drive rods of the third and fourth jacks.
[0020] The technical effects and advantages of this invention are as follows:
[0021] 1. This invention, by setting up first, second, and third core mold tubes that penetrate the mold cavity and forming a through channel inside them, allows the introduction of heat sources such as steam or hot water during the curing process, achieving three-dimensional heating of the precast concrete wall panel from the inside out. This simultaneous heating method makes the heat transfer more uniform and faster, effectively preventing cracking caused by uneven heating, shortening the curing cycle, and significantly improving curing efficiency.
[0022] 2. The pull-out movable left template design of this invention, combined with the jack push, eliminates the need for disassembling and fixing the mold side plates in the traditional way during the assembly, forming and demolding process of the mold. This makes the operation simpler and faster, which is conducive to realizing the automation and intelligence of the production line and reducing the intensity of manual labor. At the same time, the bottom template, right template, front template and rear template are fixedly connected by high-strength bolts to form a closed mold cavity. The high structural strength ensures the stability of the mold during the concrete pouring and curing process. Attached Figure Description

[0034] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of this application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0035] Example 1: As Figure 1 - Figure 9 As shown, this invention provides an energy-saving production mold for precast ceramsite concrete wall panels. Its main structure includes a fixed main mold 1 and a movable left template 2. A bottom template 3 is fixedly installed at the bottom of the main mold 1, a right template 4 is fixedly installed on the right side, a front template 5 is fixedly installed at the front, and a rear template 6 is fixedly installed at the rear. The bottom template 3, right template 4, front template 5, and rear template 6 are interconnected by high-strength bolts, forming three sides of a U-shaped closed mold cavity, ensuring the overall rigidity and stability of the mold during concrete pouring. To facilitate concrete pouring, a pouring port communicating with the mold cavity is provided on the upper part of the rear template 6.
[0036] The movable left template 2 is located on the left side of the main mold 1. The movable left template 2 can be pulled and moved relative to the main mold 1, enabling rapid mold assembly and demolding. Inside the movable left template 2, a first core mold tube 7, a second core mold tube 8, and a third core mold tube 9 are horizontally installed from top to bottom. The first core mold tube 7, the second core mold tube 8, and the third core mold tube 9 are all sealed to the movable left template 2, for example, through O-rings, sealing gaskets, or precision machining, to prevent concrete slurry from entering the first core mold tube 7, the second core mold tube 8, and the third core mold tube 9 during pouring. The gap between the outer wall and the movable left template 2; when the movable left template 2 is spliced with the main mold 1, the right ends of the first core mold tube 7, the second core mold tube 8 and the third core mold tube 9 will horizontally penetrate the right template 4 and form a sealing fit with the right template 4, ensuring the integrity of the mold cavity and the molding quality of the concrete; the left ends of the first core mold tube 7, the second core mold tube 8 and the third core mold tube 9 are all fixedly connected to the same core mold connecting plate 10 by flanges. The core mold connecting plate 10 fixes the left ends of the three core mold tubes together to form a whole, which facilitates subsequent driving and operation.
[0037] To secure the movable left template 2 after mold closing, a tension threaded tube 11 is provided on the right side of the right template 4, corresponding to the position of the second core mold tube 8. The left end of the tension threaded tube 11 is connected to the right end of the second core mold tube 8 via a threaded connection. By rotating the tension threaded tube 11, the second core mold tube 8 can be moved left and right, thereby causing the movable left template 2 to tightly fit against the main mold 1. Furthermore, the tension threaded tube 11 is an internally continuous tubular structure, and its right end is integrally formed with a disc-shaped rotating seat 1101. The rotating seat 1101 is in close contact with the right side wall of the right template 4 on the side closest to the right template 4. This design allows the rotating seat 1101 to fit tightly against the right template 4 when the tensioned threaded tube 11 rotates, providing a stable force-bearing surface and preventing twisting. A rotating rod 1102 is vertically inserted through the rotating seat 1101 along its radial direction. The rotating rod 1102 is movably connected to the rotating seat 1101, making it easier to apply torque through the rotating rod 1102, which facilitates the rotation, tightening and loosening of the tensioned threaded tube 11.
[0038] A right beam 14 is fixedly connected to the right side of the right template 4. The right beam 14 is used to provide support and fix the jacks. On the left side of the right beam 14, corresponding to the positions of the first core mold tube 7 and the third core mold tube 9, the first jack 15 and the second jack 16 are fixedly connected respectively. The axis of the first jack 15 is collinear with the axis of the first core mold tube 7, and the axis of the second jack 16 is collinear with the axis of the third core mold tube 9. This ensures that the jacks can directly and effectively apply axial thrust to the core mold tubes and avoid eccentric loading. These jacks are used to push the first core mold tube 7 and the third core mold tube 9 to the left during the demolding stage.
[0039] In a preferred embodiment, the output ends of the first jack 15 and the second jack 16 are both fixedly connected to a tube end block 17. The side of the tube end block 17 away from the jack abuts against the end of the corresponding mandrel tube. The tube end block 17 increases the contact area with the mandrel tube, disperses stress, and prevents damage to the end of the mandrel tube during the ejection process.
[0040] In another preferred embodiment, the drive rods of the first jack 15 and the second jack 16 are fixedly connected by a first coordinating rod 18. The first coordinating rod 18 is arranged vertically, and its two ends are respectively fixedly connected to the ends of the drive rods of the first jack 15 and the second jack 16, so that the two jacks can move synchronously and in a coordinated manner, ensuring that the thrust is applied evenly and avoiding tilting or jamming of the core mold tube during the ejection process.
[0041] On the left side of the movable left template 2, corresponding to the position of the core mold connecting plate 10, a third jack 27 and a fourth jack 28 are fixedly connected. The output ends of the third jack 27 and the fourth jack 28 are both in contact with the side of the core mold connecting plate 10 closest to the movable left template 2. The third jack 27 and the fourth jack 28 are used to apply a pushing force to the core mold connecting plate 10 during the second demolding stage, thereby pushing the first core mold tube 7, the second core mold tube 8 and the third core mold tube 9 to the left as a whole, so that they are completely separated from the concrete wall panel that has already been initially separated.
[0042] In a preferred embodiment, the drive rods of the third jack 27 and the fourth jack 28 are fixedly connected by a second coordinating rod 29. The second coordinating rod 29 is arranged vertically, and its two ends are respectively fixedly connected to the ends of the drive rods of the third jack 27 and the fourth jack 28. Similar to the first coordinating rod 18, it is designed to ensure that the third jack 27 and the fourth jack 28 move synchronously, provide uniform thrust, and ensure the smooth release of the core mold tube.
[0043] To prevent gaps or openings between the movable left template 2 and the front template 5 and rear template 6 due to the lateral pressure of the concrete during concrete pouring, a set of more than one set of fixing pins 12 are evenly distributed vertically along the front and rear edges of the movable left template 2. The fixing pins 12 are vertically fixed to the movable left template 2, and their axes are parallel to the axes of the first core mold tube 7, the second core mold tube 8, and the third core mold tube 9. This ensures that the insertion and removal of the fixing pins 12 are not affected by the movement of the first core mold tube 7, the second core mold tube 8, and the third core mold tube 9. The left side of the front template 5 and the rear template 6 are provided with matching first pin holes 13 corresponding to the fixing pin positions. When the movable left template 2 is spliced and tightened with the main mold 1, the fixing pins 12 can be inserted into the first pin holes 13, thereby realizing the positioning and fixing of the movable left template 2 with the front template 5 and the rear template 6, effectively preventing the mold from bulging during the pouring process, and ensuring the dimensional accuracy and appearance quality of the precast wall panels.
[0044] To enhance the overall rigidity and deformation resistance of the mold, the outer walls of the front mold 5 and the rear mold 6 are welded with crisscrossing reinforcing ribs. The reinforcing ribs are vertically fixed to the outer walls of the corresponding molds, which can effectively resist the huge lateral pressure generated during concrete pouring, prevent the mold from deforming, and thus ensure the flatness of the precast wall panels.
[0045] Example 2: Based on Example 1, the mold of the present invention proposes a structure for rapid demolding. The first core mold tube 7, the second core mold tube 8, and the third core mold tube 9 are all hollow tubular structures with openings at both ends, forming a continuous channel inside. During production, steam can be introduced into the first core mold tube 7, the second core mold tube 8, and the third core mold tube 9 to uniformly heat the ceramsite concrete in the mold cavity from the inside out. To ensure uniform heating and prevent cracking due to uneven heating during the curing of the precast wall panels, the vertical distances from the first core mold tube 7 to the upper opening of the main mold 1, the vertical distance from the third core mold tube 9 to the bottom mold plate 3, the vertical distances between the first core mold tube 7 and the second core mold tube 8, and the vertical distances between the second core mold tube 8 and the third core mold tube 9 are all equal. This equidistant and uniformly distributed core mold tube layout ensures that the heat conduction path and thermal resistance in the concrete are approximately the same, thereby ensuring a more uniform temperature distribution in the thickness direction of the concrete wall panel. This greatly reduces the risk of cracking caused by differences in thermal stress, improves product quality, and the synchronous heating inside and outside not only improves thermal efficiency but also shortens curing time, achieving energy-saving effects.
[0046] To achieve automatic separation of the core mold tube from the concrete wall panel, a bidirectional threaded rod 19 is horizontally inserted through the second core mold tube 8 and is coaxial with it. The bidirectional threaded rod 19 is rotatably connected to the second core mold tube 8 through several bearing retainers spaced apart along its axial direction. The bearing retainers ensure that the bidirectional threaded rod 19 can rotate smoothly inside the second core mold tube 8, while restricting its axial movement. One end of the bidirectional threaded rod 19 protrudes from the end of the second core mold tube 8 and is fixedly connected to a handwheel 20 for easy manual rotation. Two sets of threaded segments with opposite directions of rotation are symmetrically arranged on its rod body, namely left-hand thread and right-hand thread. A first nut 21 and a second nut 22 are symmetrically fitted onto two sets of opposite threaded sections of the bidirectional threaded rod 19. The first nut 21 and the second nut 22 are threadedly engaged with their corresponding threaded sections. When the handwheel 20 is rotated, because the two sets of threads on the bidirectional threaded rod 19 rotate in opposite directions, the first nut 21 and the second nut 22 will move towards or away from each other at the same speed. A first connecting rod 23 is rotatably connected to the first nut 21, and a round-headed pin 24 is rotatably connected to the end of the first connecting rod 23 away from the first nut 21. A second connecting rod 25 is rotatably connected to the second nut 22, and the end of the second connecting rod 25 away from the second nut 22 is also rotatably connected to the round-headed pin 24. Through this linkage mechanism, when the first nut 21 and the second nut 22 move, The extension and retraction of the round-headed pin 24 can be controlled. A second pin hole 26 is provided on the wall of the second core mold tube 8 corresponding to the position of the round-headed pin 24. The round-headed pin 24 can extend and retract along the second pin hole 26, and its end can extend out of the outer wall of the second core mold tube 8. After the concrete is poured and solidified, by turning the handwheel 20, the round-headed pin 24 can be driven to extend out of the outer wall of the second core mold tube 8 and be inserted into the reserved hole inside the concrete wall panel, thereby realizing the engagement of the core mold tube with the concrete wall panel. When it is necessary to remove the core mold tube from the wall panel, turn the handwheel 20 again to drive the round-headed pin 24 to retract into the second core mold tube 8, release the engagement with the wall panel, and create conditions for the smooth removal of the second core mold tube 8. This effectively solves the problem of concrete sticking to the core rod during demolding of traditional molds.
[0047] Example 3: The demolding process of the present invention can be summarized as follows:
[0048] Demolding preparation: After the concrete has solidified and cured, the first step is to rotate the rotating rod 1102 on the tension threaded tube 11 counterclockwise to loosen the tension threaded tube 11 from the second core mold tube 8, thereby releasing the fastening between the movable left template 2 and the main mold 1. At the same time, the fixing pin 12 is pulled out from the first pin hole 13.
[0049] First stage demolding: Activate the first jack 15 and the second jack 16. Since these two jacks move synchronously through the first coordinating rod 18, their output ends will push the first core mold tube 7 and the third core mold tube 9 to the left respectively. At this time, since the round head pin 24 on the second core mold tube 8 has extended and engaged with the inside of the concrete wall panel, the first core mold tube 7, the second core mold tube 8 and the third core mold tube 9 will be pushed to the left as a whole, together with the initially set concrete wall panel, as well as the core mold connecting plate 10 and the movable left template 2 connected to the left ends of the first core mold tube 7, the second core mold tube 8 and the third core mold tube 9, so that the entire concrete wall panel is completely separated from the bottom template 3, the right template 4, the front template 5 and the rear template 6 of the main mold 1.
[0050] Disengagement inside the core mold tube: After the entire assembly is detached from the main mold 1, the handwheel 20 is turned to drive the bidirectional threaded rod 19 inside the second core mold tube 8. The bidirectional threaded rod 19 drives the first nut 21 and the second nut 22 to move in opposite directions. Through the linkage of the first connecting rod 23 and the second connecting rod 25, the round head pin 24 retracts into the second core mold tube 8, thereby releasing the engagement between the round head pin 24 and the concrete wall panel.
[0051] Second stage demolding: The third jack 27 and the fourth jack 28 are activated. These two jacks move synchronously through the second coordinating rod 29. Their output ends will abut against the core mold connecting plate 10, applying a leftward pushing force to the core mold connecting plate 10. Since the first core mold tube 7, the second core mold tube 8 and the third core mold tube 9 are all fixedly connected to the core mold connecting plate 10, and the round head pin 24 has been retracted at this time, the internal fastening between the core mold tube and the wall panel has been released. Therefore, all the core mold tubes will be smoothly and steadily pushed to the left from the concrete wall panel that has been separated from the main mold 1, and finally the first core mold tube 7, the second core mold tube 8 and the third core mold tube 9 will be completely separated from the concrete wall panel.
[0052] In addition, to further improve demolding efficiency and wall panel surface quality, a polymer release coating is applied to the inner wall of the main mold 1, the right side wall of the movable left mold 2, and the outer walls of the first core mold tube 7, the second core mold tube 8, and the third core mold tube 9. The polymer release coating is preferably a polytetrafluoroethylene coating or a silicone rubber coating. These release coatings have excellent non-adhesion, wear resistance, and high temperature resistance, which can significantly reduce the friction between the concrete and the mold contact surface, making the demolding process more labor-saving and smooth, while protecting the surface of the concrete wall panel from damage and ensuring the appearance quality of the product.
[0053] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
