[0029] Referring to Figures 1 - 3 Figures 1 - 3 , a segment casting tooling includes a segment mold 1. A casting groove 101 is provided at the top of the segment mold 1. Legs 2 are fixedly installed at the four corners of the bottom end of the segment mold 1. A casting box 3 is placed at the top end of the segment mold 1. A feed inlet is provided at the top end of the casting box 3. A partition ring 4 is fixedly installed inside the casting box 3. A storage cavity 5 is provided above the partition ring 4 inside the casting box 3. A material distribution cavity 7 is provided below the partition ring 4 inside the casting box 3. A number of uniforming openings 8 are provided at the bottom of the casting box 3. A vibration mechanism 6 is provided at the bottom of the segment mold 1. A positioning mechanism is provided at the connection between the segment mold 1 and the casting box 3; a release agent is coated on the bottom surface of the casting box 3.
[0030] By installing the casting box 3 at the top end of the segment mold 1, the large-size feed inlet at the top of the casting box 3 is convenient for filling concrete with a concrete pouring truck. At the same time, the partition ring 4 separates the storage cavity 5 from the material distribution cavity 7, which is beneficial to the orderly flow of concrete during the casting process. At the same time, through a number of uniforming openings 8, the concrete uniformly flows out of the material distribution cavity 7 into the segment mold 1, improving the uniformity and precision of casting, and at the same time greatly reducing the operation precision required during the casting process, greatly simplifying the operation difficulty; a lubricating film is formed on the bottom surface of the casting box 3 through the release agent, which is convenient for the separation of the segment from the casting box 3 after casting.
[0031] Referring to Figures 2 - 4 Figures 2 - 4 , the vibration mechanism 6 includes a bracket 601. The bracket 601 is fixedly installed at the bottom end of the segment mold 1. A vibrator 602 is fixedly installed in the middle of the bracket 601. The vibrator 602 is in contact with the bottom surface of the segment mold 1. Rubber pads 603 are fixedly installed at the bottom ends of the legs 2; the positioning mechanism includes two sets of positioning plates 9. The two sets of positioning plates 9 are fixedly installed on both sides of the casting box 3. Two sets of positioning rods 10 are fixedly installed at the bottom end of the positioning plate 9. Two sets of positioning blocks 11 are fixedly installed on both sides of the segment mold 1. Two sets of positioning grooves 12 matching the positioning rods 10 are provided at the top of the positioning block 11;
[0032] The vibration of the vibrator 602 promotes the discharge of air bubbles in the concrete inside the segment mold 1, which is beneficial to improving the density and strength of the concrete. The rubber pads 603 reduce the direct impact of vibration on the mold, reducing defects such as honeycombing and pockmarks on the concrete surface, which is beneficial to improving the quality of the formed segments; before installing the casting box 3 above the segment mold 1, align the positioning blocks 11 with the positioning grooves 12 and snap them into the positioning grooves 12 to fix the casting box 3 on the segment mold 1. At the same time, it is beneficial to ensure the accurate positioning of the casting box 3 on the segment mold 1, avoiding the displacement of the casting box 3 during the casting process, and thus being beneficial to ensuring the casting precision of the segments.
[0033] Referring toFigures 1 - 3 At the top of both groups of positioning plates 9, lifting lugs 14 are fixedly installed; a sealing strip 13 is fixedly installed on the top surface of the segment mold 1. When moving the pouring box 3 back and forth before and after pouring, the lifting lugs 14 facilitate the hoisting and moving of the pouring box 3, thereby improving work efficiency and reducing the labor intensity of manual handling; the sealing strip 13 reduces the gap between the segment mold 1 and the pouring box 3, maintaining the sealing of the pouring environment and being conducive to improving the pouring quality.
[0034] Refer to Figure 4 A number of uniform feeding ports 8 are evenly distributed along the bottom arc surface of the pouring box 3; the feeding ports 8 are evenly distributed along the arc surface of the bottom of the pouring box 3, enabling the concrete in the pouring box 3 to uniformly flow into the segment mold 1 through a number of uniform feeding ports 8, which is conducive to the uniform distribution of concrete in the mold, thereby improving the segment quality.
[0035] Working principle: By installing the pouring box 3 at the top of the segment mold 1, the large-size feeding port at the top of the pouring box 3 facilitates the filling of concrete with a concrete pouring truck. At the same time, the partition ring 4 separates the storage cavity 5 from the distribution cavity 7, which is conducive to the orderly flow of concrete during pouring. At the same time, through a number of uniform feeding ports 8, the concrete uniformly flows out from the distribution cavity 7 into the segment mold 1, improving the uniformity and accuracy of pouring. At the same time, it greatly reduces the operation accuracy required during pouring, greatly simplifies the operation difficulty. The vibrator 602 vibrates to promote the discharge of air bubbles in the concrete inside the segment mold 1, which is conducive to improving the density and strength of the concrete. The rubber pad 603 reduces the direct impact of vibration on the mold, reducing defects such as honeycombing and pockmarks on the concrete surface, which is conducive to improving the quality of the formed segments;
[0036] Among them, a lubricating film is formed on the bottom surface of the pouring box 3 through a release agent, facilitating the separation of the segment from the pouring box 3 after pouring. Before installing the pouring box 3 above the segment mold 1, align the positioning block 11 with the positioning groove 12 and snap it into the positioning groove 12 to fix the pouring box 3 on the segment mold 1. At the same time, it is conducive to ensuring the accurate positioning of the pouring box 3 on the segment mold 1, preventing the displacement of the pouring box 3 during pouring, and thus being conducive to ensuring the pouring accuracy of the segments;
[0037] At the same time, when moving the pouring box 3 back and forth before and after pouring, the lifting lugs 14 facilitate the hoisting and moving of the pouring box 3, thereby improving work efficiency and reducing the labor intensity of manual handling; the feeding ports 8 are evenly distributed along the arc surface of the bottom of the pouring box 3, enabling the concrete in the pouring box 3 to uniformly flow into the segment mold 1 through a number of uniform feeding ports 8, which is conducive to the uniform distribution of concrete in the mold, thereby improving the segment quality;
[0038] In addition, the sealing strip 13 reduces the gap between the segment mold 1 and the pouring box 3, maintaining the sealing of the pouring environment and being conducive to improving the pouring quality.
