Description

Technical Field

[0001] This utility model relates to the field of flow regulator processing technology, and in particular to a mold for producing an integral flow regulator. Background Technology

[0002] In the steel smelting and casting process, the flow stabilizer is a key component, and its quality and performance directly affect the flow stability of molten steel and the casting effect. Traditional flow stabilizer production methods often adopt a split structure, assembled from multiple components. This method is not only complex in production process, but also results in gaps between the assembled flow stabilizer structures, making it difficult to ensure the overall tightness and sturdiness, thus affecting its performance and service life.

[0003] Furthermore, the vibration and pouring of concrete are crucial steps in the production of flow stabilizers. Traditional molds often struggle to effectively control air bubbles and excess water in the concrete during pouring, resulting in a high water-cement ratio and insufficient density, which in turn affects the strength and durability of the flow stabilizer. Additionally, traditional molds require a lengthy curing and demolding process after pouring, extending the construction period and increasing production costs. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an integral flow stabilizer production mold, which has the advantages of improving the density and strength of concrete and integral molding, and solves some of the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a mold for producing an integral flow stabilizer, comprising an outer mold body and an inner mold body. The inner mold body is placed inside the outer mold body. Movable tubes are slidably installed through the front end of the inner mold body near the left and right sides. Horizontal tubes are fixedly installed inside the inner mold body at the corresponding movable tubes. A vertical tube is slidably installed through the middle of the lower end of the inner mold body. Pre-drilled holes are provided at the bottom of both the vertical and horizontal tubes. Threaded rings are fixedly connected to the inner bottom of both the vertical and horizontal tubes. Limiting blocks are threadedly connected inside the threaded rings. Uniformly distributed air extraction holes are provided on each limiting block. Flexible suction pads are fixedly installed at the end of each limiting block near the pre-drilled hole, and the flexible suction pads are adapted to the pre-drilled holes.

[0006] Furthermore, the front end of the outer mold body is provided with an insertion hole at the corresponding movable tube. The front end of the movable tube extends outward through the insertion hole. The diameter of the limiting block is equal to the inner diameter of the movable tube. The maximum diameter of the rear end of the movable tube is equal to the inner diameter of the horizontal tube, ensuring that the limiting block and other structures can be removed from and inserted into the horizontal and vertical tubes during use.

[0007] Furthermore, a connecting pipe is fixedly connected between the horizontal pipe and the vertical pipe. The vertical pipe is connected to the horizontal pipe through the connecting pipe, thereby expanding the negative pressure area.

[0008] Furthermore, a cover plate is fixedly installed on the upper end of the inner mold body. The cover plate is adapted to the outer mold body. A pull-out opening is provided in the middle of the cover plate. A pouring hole is provided at each of the four corners of the cover plate. The cover plate provides sealing conditions at the upper end and provides support for the inner module so that its bottom is suspended.

[0009] Furthermore, each of the limiting blocks has a pull rod fixedly connected to the end away from the flexible suction pad. The upper end of the pull rod located inside the riser extends outward through the pull-out opening. A sealing cover is provided on the outside of the pull rod. The sealing cover is adapted to the pull-out opening. The pull rod facilitates the removal and placement of the flexible suction pad and other structures, and the sealing cover can be used to seal the pull-out opening.

[0010] Furthermore, a detachable Y-shaped suction pipe is fixedly installed at the front end of each of the two sets of movable tubes. A vacuum unit is fixedly installed at the front end of the Y-shaped suction pipe. The efficiency of vacuuming can be improved by using the Y-shaped suction pipe.

[0011] The advantages of this utility model are as follows:

[0012] 1. The mold of this utility model, through the sealed connection between the Y-shaped air extraction pipe and the movable pipe, combined with the vacuum sealing method of the flexible suction pad and the limiting block, can effectively remove air bubbles and excess water during the concrete pouring process. This design significantly reduces the water-cement ratio of the concrete and improves the density and strength of the concrete, thereby making the produced integral flow stabilizer have higher quality and durability.

[0013] 2. The mold adopts a movable structure design such as a movable tube. During production, simply push the movable tube to easily place the inner mold body into the outer mold body under the limit of the cover plate. After placement, pull out the movable tube and complete the subsequent processes by pulling the lever. This design allows the integral flow stabilizer to be molded in one piece, which not only makes the structure more compact and robust, but also greatly simplifies the production process. Whether it is the installation and disassembly of the inner mold body or the entire flow stabilizer manufacturing process, it becomes efficient and easy to operate, effectively improving production efficiency.

[0020] 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.

[0021] Please see Figures 1-4A mold for producing an integrated flow stabilizer includes an outer mold body 1 and an inner mold body 2. The inner mold body 2 is placed inside the outer mold body 1. Movable tubes 3 are slidably installed through the front end of the inner mold body 2 near the left and right sides. Horizontal tubes 5 are fixedly installed inside the inner mold body 2 at the corresponding positions of the movable tubes 3. A vertical tube 6 is slidably installed through the middle of the lower end of the inner mold body 2. Pre-drilled holes 7 are provided at the bottom of both the vertical tube 6 and the horizontal tube 5. Threaded rings 8 are fixedly connected to the inner bottom of both the vertical tube 6 and the horizontal tube 5. Limiting blocks 9 are threadedly connected inside the threaded rings 8. Each limiting block 9 has evenly distributed air extraction holes 1. 1. Flexible suction pads 10 are fixedly installed on the end of the limiting block 9 near the reserved hole 7. The flexible suction pads 10 are adapted to the reserved hole 7. Connecting pipes 13 are fixedly connected between the horizontal pipe 5 and the vertical pipe 6. The vertical pipe 6 is connected to the horizontal pipe 5 through the connecting pipe 13. A detachable Y-shaped air extraction pipe 17 is fixedly installed at the front end of the two sets of movable pipes 3. A vacuum unit 18 is fixedly installed at the front end of the Y-shaped air extraction pipe 17. The movable pipe 3 is pushed into the interior of the horizontal pipe 5. Thus, under the limiting action of the cover plate 14, the inner mold body 2 can be directly placed into the interior of the outer mold body 1. Then, the movable pipe 3 located in the horizontal pipe 5 is pushed into the interior of the horizontal pipe 5. Pipe 3 is pulled out and extends outward through the insertion hole 4. The longer pull rod 12 allows the limiting block 9 and flexible suction pad 10 to be placed inside the horizontal pipe 5 and vertical pipe 6, and the flexible suction pad 10 seals the pre-drilled hole 7. The threaded ring 8 allows the limiting block 9 to be threaded inside, ensuring the flexible suction pad 10 remains stable during subsequent vacuuming. The vibrated concrete material is injected into the gap between the outer mold 1 and the inner mold 2 through the pouring hole 19, and the pouring hole 19 is sealed with a suitable material. The Y-shaped suction pipe 17 is then connected to the movable pipe 3. The connection is sealed, and then a vacuum operation is performed by opening the vacuum unit 18 to create a negative pressure environment inside the horizontal pipe 5 and the vertical pipe 6. With the cooperation of the air extraction hole 11 and the flexible suction pad 10, as the vacuum time increases, the negative pressure zone will spread into the concrete, thereby allowing air bubbles and excess water in the concrete to be continuously discharged. This achieves the purpose of reducing the water-cement ratio of the concrete, increasing the density of the concrete, and enhancing the strength and durability of the concrete. At the same time, this method can also accelerate the hardening process of the concrete, allowing the concrete to reach the conditions for subsequent curing and demolding earlier, thereby shortening the construction period.

[0022] Please see Figures 2-5The front end of the outer mold body 1 is provided with an insertion hole 4 at the corresponding movable tube 3. The front end of the movable tube 3 extends outward through the insertion hole 4. The diameter of the limiting block 9 is equal to the inner diameter of the movable tube 3. The maximum diameter of the rear end of the movable tube 3 is equal to the inner diameter of the horizontal tube 5. A cover plate 14 is fixedly installed at the upper end of the inner mold body 2. The cover plate 14 is adapted to the outer mold body 1. A pull-out port 15 is provided in the middle of the cover plate 14. A pouring hole 19 is provided at each of the four corners of the cover plate 14. A pull rod 12 is fixedly connected to the end of the limiting block 9 away from the flexible suction pad 10. The upper end of the pull rod 12 located in the vertical tube 6 extends outward through the pull-out port 15. A sealing cover 16 is provided on the outer side of the pull rod 12. The sealing cover 16 is adapted to the pull-out port 15. The vacuum unit 18 and the Y-shaped suction pipe 17 are removed. Then, the limiting block 9 and the threaded ring 8 are disengaged by rotating the pull-out rod 12. The flexible suction pad 10 and other structures are then pulled out from the movable tube 3 or the pull-out port 15 by pulling the pull-out rod 12. Similarly, the movable tube 3 is pushed back into the horizontal tube 5 by using appropriate tools to release the limiting relationship between the movable tube 3 and the outer mold body 1. Then, the inner mold body 2 is taken out by using equipment such as a crane. The flow stabilizer used for molten steel pouring is located inside the outer mold body 1. The integral flow stabilizer made in this solution is a one-piece molded structure with tighter and stronger structure, which greatly improves its performance.

[0023] Working principle: During use, the movable tube 3 is pushed into the interior of the horizontal tube 5, allowing the inner mold 2 to be directly placed into the outer mold 1 under the limiting action of the cover plate 14. Then, the movable tube 3, located inside the horizontal tube 5, is pulled out again and extends through the insertion hole 4 to the outside. The longer pull rod 12 allows the limiting block 9 and the flexible suction pad 10 to be placed into the interior of the horizontal tube 5 and the vertical tube 6, and the flexible suction pad 10 seals the reserved hole 7. The threaded ring 8 allows the limiting block 9 to be threaded inside, ensuring the stability of the flexible suction pad 10 during subsequent vacuuming. The vibrated concrete material is injected into the gap between the outer mold 1 and the inner mold 2 through the pouring hole 19, and the pouring hole 19 is sealed with a suitable material. The Y-shaped suction pipe 17 is then sealed to the movable tube 3. Then, by opening the vacuum unit 18 to perform a vacuuming operation, the interior of the horizontal pipe 5 and the vertical pipe 6 is placed in a negative pressure environment. With the cooperation of the air extraction hole 11 and the flexible suction pad 10, as the vacuum time increases, the negative pressure zone will spread into the concrete, so that air bubbles and excess water in the concrete can be continuously discharged. After completion, the vacuum unit 18 and the Y-shaped air extraction pipe 17 are removed. Then, by rotating the pull rod 12, the limiting block 9 and the threaded ring 8 are disengaged, thereby pulling the pull rod 12 to remove the flexible suction pad 10 and other structures from the movable pipe 3 or the pull port 15. Similarly, by using appropriate tools, the movable pipe 3 is pushed back into the interior of the horizontal pipe 5, thereby releasing the limiting relationship between the movable pipe 3 and the outer mold body 1. Then, the inner mold body 2 is taken out by the crane or other equipment. The flow stabilizer used for molten steel pouring is located inside the outer mold body 1.
