Description

Technical Field

[0001] The present invention relates to the technical field of concrete structural component processing, and more particularly to concrete structural component processing equipment with an automatic material stripping function. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In short, they are tools used to make shaped objects. The so-called concrete structure is concrete, which is made by mixing coarse and fine aggregates, cement, and water. Sometimes, in order to enhance its strength, some chemical admixtures or steel components are added to it. It is not only resistant to compression and tension, but also solid and durable.

[0003] During the processing of concrete structures, in order to facilitate the demoulding of concrete components in the later stage, the molds are all spliced ​​together. Under special circumstances, gaps may exist at the joints of the molds, such as weak formwork support, incomplete cleaning of the inside of the molds, and poor workability of the concrete. As a result, concrete may leak from the gaps during the pouring process, which not only wastes materials but also may damage the strength and integrity of the concrete structure. When the molds are spliced ​​together, the joints cannot be sealed to avoid leakage.

[0004] Moreover, when the mold is removed, there will be residues on the inner wall of the mold. It is impossible to shake off the residues on the mold after the concrete component is automatically demolded, and then clean it, thereby shortening the cleaning steps and speeding up the processing efficiency of the concrete component. In view of the above technical defects, a solution is now provided. Summary of the Invention

[0007] A sealing component is provided on the outside of the merging component to seal the joint between the movable mold and the fixed mold; the sealing component includes two sets of connecting frames symmetrically installed on both sides of the bottom of the movable mold, and a limiting roller is rotatably provided in the connecting frame. A plurality of arc-shaped protrusions are provided on the top wall of the movable rail near the limiting roller, and the limiting roller is matched with the top of the arc-shaped protrusion and the top of the movable rail for transmission.

[0008] Furthermore, the merging assembly includes two groups of lower connecting parts arranged at the bottom of the movable mold, and upper connecting parts are arranged on both sides of the upper part of the movable mold.

[0009] Furthermore, two groups of motors 1 are provided on one of the fixing frames, an upper merging rod is provided at the output end of the motor 1, the other end of the upper merging rod is rotatably engaged with the other fixing frame through a bearing, and multiple groups of upper threaded sleeves are equidistantly provided on the upper merging rod, and the upper threaded sleeves are threadedly connected to the corresponding upper connecting pieces.

[0010] Furthermore, a lower merging rod is provided between the multiple groups of lower connecting members located on the same side, and multiple groups of lower threaded sleeves are equidistantly provided on the outer wall of the lower merging rod, and the lower threaded sleeves are threadedly connected to the corresponding lower connecting members.

[0011] Furthermore, a second motor is fixedly provided on one end of the lower merging rod, and the second motor is connected to the base. The other end of the lower merging rod is rotatably connected to the base through a bearing.

[0012] Furthermore, the upper connecting part consists of a lower connecting block, an upper connecting block and a connecting spring. The lower connecting block is fixedly connected to the movable mold, and the upper connecting block is slidably arranged in the lower connecting block. The top of the upper connecting block is connected to the upper threaded sleeve, and a connecting spring is arranged between the bottom of the upper connecting block and the inner wall of the lower connecting block.

[0013] Furthermore, a connecting plate is fixedly provided on the outer side of the connecting frame, a rack is fixedly provided on the end of the connecting plate, a gear is meshed and connected on the outer wall of the rack, and a rotating shaft 1 is fixedly provided at the center of the gear.

[0014] Furthermore, a threaded rod is fixedly provided at the end of the rotating shaft 1, and a vertical plate is threadedly connected to the outer wall of the threaded rod. A sealing plate is fixedly provided on the top of the vertical plate, and a limiting plate is slidably connected to the upper part of the vertical plate.

[0015] Furthermore, the ends of the rotating shaft 1 and the limiting plate are connected to their corresponding movable rails, and the end of the threaded rod and the other end of the limiting plate are connected to the base through a mounting plate.

[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention controls the rotation of two groups of upper merging rods and two groups of lower merging rods to control the movable mold to synchronously fit toward the fixed mold to form a molding cavity. At the same time, the limiting roller moves from the initial position to the merging position, the connecting frame drives the rack to move to one side, the gear rotates, and the threaded rod at the center rotates, controlling the sealing plates on both sides of the molding cavity to move closer to the fitting of the fixed mold and the movable mold, sealing the fitting, and preventing concrete from leaking from the fitting of the two, resulting in leakage, forming defects such as roughness and honeycomb on the surface of the concrete structural component, and affecting the aesthetics of the component.

[0018] 2. The present invention controls the movable mold to move from the merging position to one side of the initial position. After reaching the initial position, the concrete structural component is automatically demoulded. Then, the concrete structural component in the molding cavity is transferred by the lifting tool in cooperation with the top of the concrete structural component.

[0019] In the process from the initial position to the cleaning position: the rack drives the gear to rotate in the opposite direction, thereby moving the two sealing plates to the side away from the molding cavity, and the limiting roller at the bottom of the movable mold cooperates with the upper surface of the arc-shaped protrusion to realize the vibration of the movable mold, and shake off a small amount of residue on the inside of the movable mold. With the help of manual or auxiliary cleaning equipment, the residue on the fixed mold can be cleaned, shortening the cleaning steps and accelerating the manufacturing efficiency of concrete structural components.

[0020] 3. The present invention takes two perspectives, namely, merging the molds and removing the molds, into consideration. That is, when the molds are merged, the gap between the fixed mold and the movable mold is sealed to prevent leakage of the slurry. When removing the molds, the residue on the movable mold is first shaken off and auxiliary equipment is used before the mold is cleaned, thereby shortening the mold cleaning steps. The two cooperate with each other to not only improve the quality of processed concrete structural components, but also improve processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

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

[0031] Example 1: Please refer to Figures 1-8 As shown, the problem in the prior art that after the concrete component is automatically demoulded, the residue on the mold cannot be shaken off first and then cleaned, thereby shortening the cleaning steps, can be solved by the following solution;

[0032] This embodiment provides a concrete structural component processing device with an automatic material stripping function, including a base 1 and two sets of movable rails 2 fixedly installed above the base 1, two sets of fixed frames 3 fixedly installed above the base 1, multiple sets of movable molds 4 are commonly arranged above the two sets of movable rails 2, and the multiple sets of movable molds 4 are connected to the multiple sets of fixed molds 5 through a merging component 7, and a sealing component 6 is provided on the outer side of the merging component 7 to seal the joint between the movable molds 4 and the fixed molds 5;

[0033] The merging assembly 7 includes two groups of lower connecting members 74 arranged at the bottom of the movable mold 4, and upper connecting members 73 are arranged on both sides of the upper part of the movable mold 4. Two groups of motors 1 are arranged on one fixed frame 3. The output end of motor 1 is provided with an upper merging rod 71. The other end of the upper merging rod 71 is rotatably engaged with the other fixed frame 3 through a bearing. Multiple groups of upper threaded sleeves are equidistantly arranged on the upper merging rod 71, and the upper threaded sleeves are threadedly connected to their corresponding upper connecting members 73; a lower merging rod 76 is provided between the multiple groups of lower connecting members 74 on the same side;

[0034] Then, by controlling the motor 1 and the motor 2 to drive the upper merging rod 71 and the lower merging rod 76 to rotate in opposite directions, the movable mold 4 moves from the merging position to one side of the initial position. After reaching the initial position, the concrete structural component is automatically demoulded. Then, the concrete structural component in the molding cavity is transferred by cooperating with the top of the concrete structural component through the conventional external lifting tooling;

[0035] Multiple sets of lower threaded sleeves are equidistantly provided on the outer wall of the lower merging rod 76, and the lower threaded sleeves are threadedly connected to their corresponding lower connecting members 74. One end of the lower merging rod 76 is fixedly provided with a second motor, which is connected to the base 1. The other end of the lower merging rod 76 is rotatably connected to the base 1 through a bearing.

[0036] A plurality of arc-shaped protrusions 75 are provided on the top wall of the movable rail 2 near the movable mold 4;

[0037] In the process of moving the mold 4 from the initial position to the cleaning position: the rack 63 drives the gear 64 to rotate in the opposite direction, thereby moving the two sealing plates 68 to the side away from the molding cavity, and the limiting roller 69 at the bottom of the movable mold 4 cooperates with the upper surface of the arc-shaped protrusion 75 to achieve vibration of the movable mold 4, shaking off a small amount of residue inside the movable mold 4. With the help of manual or auxiliary equipment, the residue on the fixed mold 5 is cleaned, shortening the cleaning steps and accelerating the manufacturing efficiency of the concrete structural components.

[0038] The upper connecting member 73 is composed of a lower connecting block 731, an upper connecting block 732 and a connecting spring 733. The lower connecting block 731 is fixedly connected to the movable mold 4, and a cavity is formed inside the lower connecting block 731. The upper connecting block 732 is slidably arranged inside the cavity. The top of the upper connecting block 732 extends to the outside of the lower connecting block 731 and is connected to the upper threaded sleeve. A connecting spring 733 is provided between the bottom of the upper connecting block 732 and the inner wall of the lower connecting block 731.

[0039] It should be noted that the lower connecting block 731 and the upper connecting block 732 have the same structure, but are arranged in reverse order to provide a foundation for the shaking of the movable mold 4.

[0040] In order to reduce the adhesion between the concrete and the mold and ensure the smooth release of the concrete component, a release agent is often sprayed on the inside of the mold. Therefore, when the movable mold 4 is separated from the fixed mold 5, the concrete component can be automatically demoulded. The release agent is sprayed after the mold is cleaned.

[0041] Common release agents include the following categories: pure oil release agents, which have good isolation and lubrication properties and are easy to demould, and have a certain anti-rust protection effect on steel formwork or reinforced concrete formwork; emulsion release agents, which are simple to operate, low in cost, and have a good component appearance; solvent release agents, which have good demoulding properties, are not affected by weather, and have basically no defects in the appearance of components; saponified oil release agents, which have easy-to-obtain raw materials, low production costs, simple preparation processes, and easy operation, and are suitable for wooden formwork, ground formwork, etc.; paraffin release agents, which have a good degassing effect on the surface of concrete products and have stronger rain resistance than other emulsion release agents; synthetic resin release agents, which have a very good demoulding effect and can be used multiple times, but are more expensive and difficult to clean the formwork when renewing the coating; that is, choose the best release agent based on the actual production situation;

[0042] Example 2: Please refer to Figure 1-Figure 3 、 Figure 5-Figure 8 As shown, when the mold is not firmly supported, the internal cleaning of the mold is not thorough, and the workability of the concrete is poor, it is impossible to seal the joints of the mold to avoid leakage. The following solutions can be used to solve the problem;

[0043] The sealing assembly 6 in this embodiment includes two sets of connecting frames 61 symmetrically mounted on both sides of the bottom of the movable mold 4. A limit roller 69 is rotatably provided in the connecting frame 61. A plurality of arc-shaped protrusions 75 are provided on the top wall of the movable rail 2 near the limit roller 69. The limit roller 69 is in transmission engagement with the top of the arc-shaped protrusion 75 and the top of the movable rail 2.

[0044] A connecting plate 62 is fixedly provided on the outer side of the connecting frame 61, and a rack 63 is fixedly provided on the end of the connecting plate 62. A gear 64 is meshed and connected to the outer wall of the rack 63. A rotating shaft 1 65 is fixedly provided at the center of the gear 64. A threaded rod is fixedly provided on the end of the rotating shaft 1 65, and a vertical plate 67 is threadedly connected to the outer wall of the threaded rod. A vertically arranged limiting plate 66 is slidably connected above the vertical plate 67. The ends of the rotating shaft 1 65 and the limiting plate 66 are connected to their corresponding movable rails 2, and the other ends of the end of the threaded rod and the limiting plate 66 are connected to the base 1 through the mounting plate; a sealing plate 68 is fixedly provided above the vertical plate 67;

[0045] The movable mold 4 is controlled to synchronously fit toward the fixed mold 5 to form a molding cavity. The limiting roller 69 moves from the initial position to the merging position. The connecting frame 61 drives the rack 63 to move to one side. The gear 64 rotates, so the threaded rod at the center rotates, controlling the sealing plates 68 on both sides of the molding cavity to move closer to the fitting position, sealing the fitting position to prevent concrete from leaking out of the fitting position and causing slurry leakage.

[0046] When disassembling the mold, the motor 1 and the motor 2 are controlled to drive the upper merging rod 71 and the lower merging rod 76 to rotate in opposite directions, and the movable mold 4 moves from the merging position to one side of the initial position. After reaching the initial position, the demoulding of the concrete structural component is automatically completed, and the rack 63 drives the gear 64 to rotate in the opposite direction, and the two sealing plates 68 are moved to the side away from the molding cavity.

[0047] It should be noted that the threaded rods on both sides of the two movable rails 2 have opposite thread directions, i.e., one side of the threaded rod has a right-hand thread and the other side has a left-hand thread, so as to ensure that when the threaded rod rotates, the sealing plate 68 is synchronously moved closer to the fitting gap between the fixed mold 5 and the movable mold 4.

[0048] It needs to be explained that: the concrete has poor workability and a high water-cement ratio, which causes the stones to sink to the bottom. During the vibration process, the gaps in the formwork are widened, resulting in leakage.

[0049] The present invention is based on the first and second embodiments. From the perspectives of mold merging and mold removal, the gap between the fixed mold 5 and the movable mold 4 is sealed when the molds are merged, thereby preventing leakage of slurry and ensuring the aesthetics of the concrete component. When the molds are removed, the residue on the movable mold 4 is first shaken off and auxiliary equipment is used before cleaning the mold, thereby shortening the mold cleaning step. The two cooperate with each other, thereby not only improving the quality of the processed concrete structural components, but also improving the processing efficiency.

[0050] The working process and principle of the present invention are as follows:

[0051] Step 1: Merge molds:

[0052] Control motor 1 and motor 2 to start, and the two sets of upper merging rods 71 ​​and the two sets of lower merging rods 76 rotate synchronously in the same direction and at the same speed, controlling the movable mold 4 to synchronously fit toward the fixed mold 5 to form a fixed cavity; during this process, the limiting roller 69 moves from the initial position to the merging position, the connecting frame 61 drives the rack 63 to move to one side, and the gear 64 rotates, so that the threaded rod at the center rotates, controlling the sealing plates 68 on both sides of the fixed cavity to move closer to the fitting position, sealing the fitting position, and preventing concrete from leaking out from the fitting position of the two, causing slurry leakage, and forming defects such as pitting and honeycombing on the surface of the concrete structural component, which affects the aesthetics of the component;

[0053] Step 2: pouring:

[0054] Pour the mixed concrete slowly and evenly into the molding cavity to avoid bubbles and voids. During the pouring process, use a vibrator to vibrate the concrete to make it more compact and expel the bubbles. After pouring, the concrete structural components are cured and demolded.

[0055] Step 3: Demolding:

[0056] Control motor 1 and motor 2 to drive the upper merging rod 71 and the lower merging rod 76 to rotate in opposite directions, and move the movable mold 4 from the merging position to one side of the initial position. After reaching the initial position, the concrete structural component is automatically demoulded, and then the concrete structural component in the molding cavity is transferred by cooperating with the top of the concrete structural component through the lifting tool;

[0057] In the process of moving from the merging position to the initial position to the cleaning position: the rack 63 drives the gear 64 to rotate in the opposite direction, thereby moving the two sealing plates 68 to the side away from the molding cavity, and the limiting roller 69 at the bottom of the movable mold 4 cooperates with the upper surface of the arc-shaped protrusion 75 to achieve vibration of the movable mold 4, shaking off a small amount of residue inside the movable mold 4, and cooperating with manual or auxiliary equipment to clean the residue on the fixed mold 5, shortening the cleaning steps and accelerating the manufacturing efficiency of the concrete structural components;

[0058] In summary, the present invention is based on the two perspectives of merging molds and demolding. That is, when merging the molds, the fitting gap between the fixed mold 5 and the movable mold 4 is sealed to avoid leakage of the slurry. When demolding, the residue on the movable mold 4 is first shaken off with auxiliary equipment and then the mold is cleaned, which shortens the mold cleaning step. The two cooperate with each other, which not only improves the quality of processed concrete structural components, but also improves the processing efficiency.

[0059] Obviously, many modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification in order to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
