[0002] Cast iron ductile manhole cover casting refers to the process of using ductile iron materials to make manhole covers. The molten ductile iron liquid is poured into a pre-prepared sand mold or metal mold. After cooling and solidification, it forms the required manhole cover shape and size. This process involves the smelting of ductile iron materials, the design of the pouring system, the production and assembly of the mold, the pouring operation, and the subsequent cooling, demolding, cleaning and heat treatment steps. Ductile iron has been widely used in manhole cover manufacturing due to its high strength, good toughness and corrosion resistance. The pouring process requires strict control of temperature, speed and pouring volume to ensure that the ductile iron liquid can fully fill the mold and avoid defects such as pores and shrinkage holes. At the same time, the design and production of the mold is also one of the key factors affecting product quality. It is necessary to ensure the accuracy, rigidity and durability of the mold.

Two fixed blocks are usually provided at the bottom of the support frame. The two fixed blocks are movably arranged in two tracks arranged on the running rail. A plurality of pouring molds are also provided on the running rail. The pouring effect is achieved by moving the position of the pouring body on the running rail. However, in the existing pouring process, since a certain distance is provided between the position of the discharge port of the pouring body and the pouring mold, the position of the pouring body is usually positioned manually, that is, the position of the pouring body on the running rail is judged and positioned by manual naked eye observation.

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1-Figure 6 ,in, Figure 1A schematic diagram of the overall structure of the cast iron ductile iron manhole cover positioning and pouring device provided by the utility model; Figure 2 A partial schematic diagram of the running rail provided by the utility model;

[0024] In the specific implementation process, Figure 1-Figure 6 As shown, a cast iron ductile manhole cover positioning pouring device comprises a pouring assembly, a running rail 5 is arranged at the bottom of the pouring assembly, the bottom of the pouring assembly is movably connected with the inner side walls of two tracks arranged on the running rail 5 through two fixed blocks 10, and a spacing is arranged between the bottom ends of the two fixed blocks 10 and the inner side bottom walls of the two tracks respectively, a plurality of positioning assemblies for synchronously limiting the two fixed blocks 10 are equidistantly arranged on the running rail 5, and the spacing between the plurality of positioning assemblies is consistent with the size of the two fixed blocks 10, and the sides of the plurality of positioning assemblies away from the pouring assembly are all arranged in an arc shape;

[0025] The positioning assembly includes a positioning rod 3, a support block 4 and a reset group. A movable groove 7 is provided on the casting assembly. The positioning rod 3 is movably arranged in the movable groove 7. The side of the positioning rod away from the casting assembly is arranged in an arc shape. The reset group is arranged on the side of the positioning rod 3 away from the movable groove 7. A fixed groove is provided on the support block 4. The side of the reset group away from the positioning rod 3 is fixedly connected to the inner bottom wall of the fixed groove. One side of the support block 4 is fixedly connected to one side of the casting assembly.

[0026] During specific use, when the pouring assembly contacts the arc-shaped side wall of the positioning rod 3, the pouring assembly directly passes through the upper end of the positioning rod 3, and there is no need to manually adjust the positioning rod 3, which simplifies the overall operation process. When the pouring assembly completely passes through the positioning rod 3, the position of the positioning rod can be reset by the reset group, which does not affect the subsequent use of the device.

[0027] The reset group includes a first movable rod 11, a second movable rod 12 and a spring 13. The upper end of the first movable rod 11 is fixedly connected to the bottom end of the positioning rod 3. The end of the first movable rod 11 away from the positioning rod 3 is movable and extends to the inside of the second movable rod 12. The end of the first movable rod 11 close to the second movable rod 12 is fixedly connected to one end of the spring 13. The end of the spring 13 away from the first movable rod 11 is fixedly connected to the inner bottom wall of the second movable rod 12. The end of the second movable rod 12 away from the first movable rod 11 is fixedly connected to the inner bottom wall of the fixing groove.

[0028] During specific use, the positioning rod 3 is moved in a direction close to the supporting block 4, and finally the bottom of the positioning rod 3 is fitted on the supporting block 4. In this process, the movement of the positioning rod 3 will push the first movable rod 11 to the inside of the second movable rod 12, and will compress the spring 13, and then the fixed block 10 can be moved. Since a gap is provided between the bottom end of the fixed block 10 and the inner bottom walls of the two tracks, respectively, the positioning rod 3 can pass through the gap, so that it will not affect the operation of the overall device. When the fixed block 10 moves to a suitable position, the positioning rod 3 will pop out due to the force of the spring 13, so that the effect of limiting the fixed block 10 is achieved again;

[0029] The above-mentioned movement of the positioning rod 3 can be performed by manual stepping, making the overall implementation process more convenient;

[0030] The casting assembly includes a casting body 1 and a support frame 2. The casting body 1 is mounted on the support frame 2. The bottom end of the support frame 2 away from the casting body 1 is fixedly connected to the upper ends of two fixed blocks 10 respectively. A plurality of casting molds 6 are fixedly arranged at equal distances on the upper end of the running rail 5.

[0031] The opposite sides of the fixed block 10 are fixedly connected with mounting plates 9, and the inner side walls on the opposite sides of the track are provided with limiting grooves 8, and the two mounting plates 9 are respectively movably arranged in the two limiting grooves 8 and slide along the two limiting grooves 8;

[0032] During the specific implementation process, the two mounting plates 9 are arranged to limit the vertical direction of the fixing block 10, so that there is a certain distance between the fixing block 10 and the inner bottom wall of the track, and the fixing block 10 is prevented from fitting with the inner bottom wall of the track due to the effect of gravity.

[0033] The working principle provided by the utility model is as follows: during the use of the device, by setting a plurality of positioning rods 3, and the spacing between the plurality of positioning rods 3 is consistent with the size of the two fixing blocks 10, the entire device can be used to accurately position the casting assembly during operation through the plurality of positioning rods 3;

[0034] When it is necessary to adjust the position of the fixed block 10, the positioning rod 3 can be moved in a direction close to the supporting block 4, and finally the bottom of the positioning rod 3 will fit on the supporting block 4. In this process, the movement of the positioning rod 3 will push the first movable rod 11 to the inside of the second movable rod 12, and will compress the spring 13. Then the fixed block 10 can be moved. Since a gap is provided between the bottom end of the fixed block 10 and the inner bottom walls of the two tracks, the positioning rod 3 can pass through the gap, so that it will not affect the operation of the overall device. When the fixed block 10 moves to a suitable position, the positioning rod 3 will pop out due to the force of the spring 13, so that the effect of limiting the fixed block 10 can be achieved again.
