Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casting, in particular to a machine seal snap ring piece casting mold with anti-run-on function. BACKGROUND

[0002] In the traditional casting process of machine seal snap ring pieces, many problems often occur. For example, the run-on phenomenon often occurs, which not only causes serious safety hazards and threatens the safety of operators, but also leads to a significant decline in product quality and increases production costs. At the same time, the utilization rate of metal materials is low, and a large amount of unqualified products and excess metal waste are discarded, causing great waste of resources. Moreover, the production efficiency is not high, and the synergy of each link in the casting process is poor, resulting in a long forming time of the machine seal snap ring piece, which cannot meet the demand of large-scale production.

[0003] In addition, the product quality is unstable, and due to factors such as uneven metal melt and inconsistent cooling speed, defects such as pores and cracks are easily produced, affecting the performance and service life of the machine seal snap ring piece. And reference the patent document with publication number CN212917531U, which can quickly cool the casting mold, focuses on how to quickly cool the mold, and does not have the function of preventing run-on, and similarly cannot recycle the excess waste during the extrusion process, which will cause waste of resources and reduce production efficiency. SUMMARY

[0004] The purpose of the present application is to provide a machine seal snap ring piece casting mold with anti-run-on function to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a machine seal snap ring piece casting mold with anti-run-on function, comprising a casting device and a controller, the casting device comprising a rack, the rack being provided with a smelting pot, a driving assembly, a pushing assembly, a solidification assembly and a recovery tank, the driving assembly being provided with a pouring assembly between the driving assemblies; The pouring assembly is provided with a mold on both sides; The driving assembly can drive the pouring assembly to move between the racks; The smelting pot can add metal melt to the pouring assembly; The pushing assembly and the recovery tank are located between the solidification assembly.

[0006] Further, the pouring assembly comprises a pouring pipe, the pouring pipe is provided with a plurality of inner gates, the inner gates are provided with connecting grooves outside, the mold is connected with the inner gates through the connecting grooves, the pouring pipe is provided with a discharge port at the bottom, and the discharge port cooperates with the recovery tank.

[0007] Furthermore, the drive assembly includes a drive motor and two sets of drive rods, with a limit rod installed between the two sets of drive rods, and the casting pipe installed between the limit rods.

[0008] Furthermore, the melting tank is mounted on the frame, and a heating device and a stirring assembly are provided inside the melting tank. The heating device can heat and melt the metal inside the melting tank. The stirring assembly includes a stirring rod, on which a mounting ring is mounted. Several support rods are mounted outside the mounting ring, and the support rods are equidistantly mounted on the mounting ring. An outer ring is mounted on the other end of each support rod, and the outer ring contacts the inner wall of the melting tank.

[0009] Furthermore, the stirring rod is provided with a bidirectional thread, and the mounting ring is provided with a bidirectional threaded groove, wherein the bidirectional thread and the bidirectional threaded groove engage.

[0010] Furthermore, the material pushing assembly includes a driving device and a material pushing block. The material pushing block is installed at the bottom of the driving device and is connected to the pouring pipe. Several cylinders are embedded in the material pushing block, and a stripping module is installed at the output end of the cylinder. The stripping module cooperates with the inner gate.

[0011] Furthermore, the solidification assembly includes two sets of solidification plates, which are respectively disposed on both sides of the frame. Several semiconductor cooling plates are mounted on the solidification plates, and the semiconductor cooling plates are equidistantly mounted on the solidification plates. The semiconductor cooling plates are connected to the controller.

[0012] Furthermore, the recycling tank is located between two sets of solidification plates, and a heating device is also installed inside the recycling tank. The recycling tank is connected to the smelting tank.

[0013] Furthermore, when the driving component moves the casting component between the two sets of solidification plates and above the recovery tank, the pushing component will squeeze the casting component to squeeze out the residual melt inside the casting component.

[0014] Furthermore, the controller is installed on the side of the frame, and the controller is equipped with a control panel. The controller is electrically connected to the melting tank, the drive assembly, the pusher assembly, and the solidification assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When using this device, the mold must first be installed on the casting assembly. Then, the drive assembly is started to move the casting assembly below the melting tank. The melting tank adds molten metal into the casting assembly, which then flows into the mold. The drive assembly moves the casting assembly between the solidification assembly and the recycling tank. The pusher assembly then pushes it to the recycling tank. Defective products or excess metal scrap can be directly recycled into the recycling tank for subsequent reuse. 2. When the casting assembly of this device is in use, the molten metal flows from the melting tank into the casting pipe and then flows evenly to the mold through the ingate. The design of the connecting groove ensures a tight connection between the mold and the ingate, effectively preventing leakage of the molten metal during the flow process and further enhancing the fire prevention function. The setting of the discharge port is very ingenious. After the casting is completed, the excess molten metal can flow directly into the recovery tank through the discharge port, avoiding the fire hazard caused by the molten metal remaining in the casting pipe. 3. When the stirring rod of the stirring assembly rotates, the mounting ring will rotate accordingly, which in turn drives the support rod mounted on it to rotate. The outer ring at the other end of the support rod will rotate along the inner wall of the melting tank. This design makes the stirring more thorough and can effectively avoid local overheating or undercooling of the molten metal, ensuring the uniformity of the molten metal. After the uniform molten metal flows into the casting assembly and mold, it can improve the quality of the mechanical seal ring and reduce product defects caused by uneven metal composition.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example: Figures 1-7 As shown, the present invention provides a casting mold for a mechanical seal ring with anti-fire function, including a frame 11, on which a melting tank 12, a drive assembly 2, a pusher assembly 3, a solidification assembly 4 and a recovery tank 13 are installed, and a casting assembly 5 is installed between the drive assemblies 2. Molds are installed on both sides of the casting component 5; Drive component 2 can drive casting component 5 to move between frames 11; The melting pot 12 is capable of adding molten metal into the casting assembly 5; The feeding assembly 3 and the recovery tank 13 are located between the solidification assembly 4; When using this device, the mold must first be installed on the casting assembly 5. Then, the drive assembly 2 is activated, moving the casting assembly 5 below the melting tank 12. The melting tank 12 adds molten metal into the casting assembly 5, which then flows into the mold. The drive assembly 2 then moves the casting assembly 5 between the solidification assembly 4 and the recovery tank 13. First, the pusher assembly 3 continues to push it to the recovery tank 13. Defective products or excess metal scrap can be directly recycled into the recovery tank 13 for subsequent reuse. Then, the pusher assembly 3 starts working, pushing the cast mechanical seal ring out of the mold and into the solidification assembly 4 for further processing. Solidification: Solidification component 4 can accelerate the solidification process of the mechanical seal ring through cooling systems and other means, improving production efficiency. Throughout the casting process, the various components work closely together. The precise movement of drive component 2 ensures the accuracy of the pouring position, the orderly movement of push component 3 realizes the product's ejection and recovery, and the efficient cooling of solidification component 4 ensures product quality. Moreover, the mold's anti-fire function plays a crucial role in the entire casting process. It can effectively prevent the molten metal from escaping during pouring, avoiding safety accidents and product quality problems caused by fire, and improving the safety and reliability of the casting work.

[0019] like Figures 1-2 and Figure 4As shown, in this embodiment, specifically, the casting component 5 includes a casting pipe 51, which is provided with a plurality of inner gates. A connecting groove 52 is installed outside the inner gates. The mold is connected to the inner gates through the connecting groove 52. A discharge port is provided at the bottom of the casting pipe 51, which is matched with the recycling tank 13. When the casting component 5 of this device is in use, the molten metal flows from the melting tank 12 into the casting pipe 51 and then flows evenly to the mold through the ingate. The design of the connecting groove 52 ensures a tight connection between the mold and the ingate, effectively preventing leakage of the molten metal during the flow process and further enhancing the fire prevention function. The setting of the discharge port is very ingenious. After the casting is completed, the excess molten metal can flow directly into the recovery tank 13 through the discharge port, avoiding the fire hazard caused by the molten metal remaining in the casting pipe 51. At the same time, the cooperation between the discharge port and the recovery tank 13 makes the whole recovery process smoother and improves the utilization rate of metal materials. During the casting process, the structure and layout of the casting pipe 51 have also been carefully designed to ensure that the molten metal flows into the mold at a suitable speed and flow rate, ensuring the molding quality of the mechanical seal retaining ring.

[0020] like Figures 1-3 As shown, in this embodiment, specifically, the drive assembly 2 includes a drive motor 21 and two sets of drive rods 22, a limit rod 23 is installed between the two sets of drive rods 22, and a casting pipe 51 is installed between the limit rods 23; When the drive assembly 2 of the device is in use, after the drive motor 21 is started, it will drive the two sets of drive rods 22 to rotate. Since the limiting rod 23 is installed between the two sets of drive rods 22 and the pouring pipe 51 is installed between the limiting rods 23, the rotation of the drive rod 22 will be transmitted to the pouring pipe 51 through the limiting rod 23, thereby driving the pouring pipe 51 to move between the frames 11. The setting of the limiting rod 23 plays an important role. It not only ensures the stability of the pouring pipe 51 during the movement process, avoiding its shaking or deviation, and thus ensuring the accuracy of the pouring position, but also effectively limits the movement range of the pouring pipe 51, so that it can only move on the specified path, further improving the reliability of the entire casting process.

[0021] like Figures 1-2 and Figure 5 As shown, in this embodiment, specifically, the melting tank 12 is installed on the frame 11. The melting tank 12 is equipped with a heating device and a stirring assembly 6. The heating device can heat and melt the metal in the melting tank 12. The stirring assembly 6 includes a stirring rod 61, a mounting ring 62 is installed on the stirring rod 61, and a plurality of support rods 63 are installed on the outside of the mounting ring 62. The support rods 63 are equidistantly installed on the mounting ring 62, and an outer ring 64 is installed at the other end of the support rods 63. The outer ring 64 is in contact with the inner wall of the melting tank 12. When the melting tank 12 of this device is in use, the heating device heats the metal to its melting point and melts it into molten metal. When the stirring rod 61 of the stirring assembly 6 rotates, the mounting ring 62 rotates accordingly, which in turn drives the support rod 63 mounted on it to rotate. The outer ring 64 at the other end of the support rod 63 rotates along the inner wall of the melting tank 12. This design makes the stirring more thorough and can effectively avoid local overheating or undercooling of the molten metal, ensuring the uniformity of the molten metal. After the uniform molten metal flows into the casting assembly 5 and the mold, it can improve the quality of the mechanical seal ring and reduce product defects caused by uneven metal composition. At the same time, the contact between the outer ring 64 and the inner wall of the melting tank 12 can also play a certain scraping role, preventing the molten metal from adhering to the tank wall, avoiding waste of metal materials, and facilitating subsequent cleaning work. Moreover, the continuous stirring of the stirring assembly 6 can promote the discharge of gas in the molten metal, further improving the molding quality of the mechanical seal ring and reducing the generation of defects such as porosity.

[0022] like Figure 5 As shown, in this embodiment, specifically, the stirring rod 61 is provided with a bidirectional thread, and the mounting ring 62 is provided with a bidirectional threaded groove, and the bidirectional thread and the bidirectional threaded groove mesh with each other; Because the stirring rod 61 of the device is provided with a bidirectional thread and the mounting ring 62 is provided with a bidirectional threaded groove, and the two mesh with each other, when the stirring rod 61 rotates, the mounting ring 62 will move up and down along the stirring rod 61 under the action of the bidirectional thread and the bidirectional threaded groove. This movement further enhances the stirring effect, making the molten metal more fully mixed in the melting tank 12.

[0023] like Figure 1 and Figure 6 As shown, in this embodiment, specifically, the pusher assembly 3 includes a drive device and a pusher block 31. The pusher block 31 is installed at the bottom of the drive device. The pusher block 31 is connected to the pouring pipe 51. Several cylinders are embedded in the pusher block 31. A stripping module 32 is installed at the output end of the cylinder. The stripping module 32 cooperates with the inner gate. When the pusher assembly 3 of this device is in use, the drive device will drive the pusher block 31 to move. Since the pusher block 31 is connected to the gating pipe 51, the pusher block 31 can move with the position change of the gating pipe 51. When the cast mechanical seal retaining ring needs to be removed from the mold, the cylinder embedded in the pusher block 31 starts to work. The ejector module 32 at the output end of the cylinder will cooperate with the ingate under the push of the cylinder to smoothly push the mechanical seal retaining ring out of the mold. The precise cooperation between the ejector module 32 and the ingate ensures the accuracy of the pusher process and avoids damage to the mechanical seal retaining ring. Moreover, this pusher method can complete the removal of mechanical seal retaining rings at multiple ingates at one time, which greatly improves production efficiency. At the same time, the reasonable design of the pusher assembly 3 also makes the entire casting process more automated, reduces manual intervention, and reduces labor intensity.

[0024] like Figure 1 and Figure 7 As shown, in this embodiment, specifically, the solidification component 4 includes two sets of solidification plates 41, which are respectively arranged on both sides of the frame 11. Several semiconductor cooling plates are installed on the solidification plates 41, and the semiconductor cooling plates are equidistantly installed on the solidification plates 41. The semiconductor cooling plates are connected to the controller 7. When the solidification component 4 of the device is in use, the controller 7 will control the semiconductor cooling plate to start working according to the set parameters. The semiconductor cooling plate is equidistantly installed on the solidification plate 41, which can evenly dissipate cold energy and form a low temperature area on the surface of the solidification plate 41. The two sets of solidification plates 41 are respectively set on both sides of the frame 11. This layout can cool and solidify multiple mechanical seal ring parts at the same time, further improving production efficiency and enabling the mechanical seal ring parts in the mold to solidify and form quickly so as to facilitate separation from the mold.

[0025] like Figure 1 and Figure 7 As shown, in this embodiment, specifically, the recovery tank 13 is located between the two sets of solidification plates 41, and a heating device is also installed inside the recovery tank 13. The recovery tank 13 is connected to the smelting tank 12. The heating device installed inside the recycling tank 13 of this device can heat the recycled substandard products or excess metal scrap, remelting them into molten metal. Since the recycling tank 13 is connected to the smelting tank 12, the remelted molten metal can be transported back to the smelting tank 12, realizing the recycling of metal materials and greatly reducing production costs. During the transportation process, it can be controlled by devices such as pipes and valves to ensure that the molten metal flows safely and stably from the recycling tank 13 into the smelting tank 12. The heating device in the tank treats the recycled metal scrap, avoiding the accumulation and oxidation of the scrap at room temperature, ensuring the quality of the recycled metal, and providing high-quality raw materials for subsequent casting production. This makes the entire casting process an efficient, environmentally friendly, and circular production system, further enhancing the device's fire-proof function.

[0026] like Figures 1-2 As shown, in this embodiment, specifically, when the driving component 2 moves the casting component 5 between the two sets of solidification plates 41 and above the recovery tank 13, the pushing component 3 will squeeze the casting component 5 to squeeze out the residual melt inside the casting component 5. When the pusher assembly 3 extrudes the casting assembly 5, to ensure a smooth and efficient extrusion process, the drive device of the pusher assembly 3 applies precise force, causing the pusher block 31 to act evenly on the casting assembly 5. At this time, the residual molten liquid inside the casting assembly 5 will flow out quickly and unimpeded from the discharge port under pressure into the recovery tank 13 below, preventing the residual molten liquid from solidifying inside the casting assembly 5 and avoiding any impact on subsequent casting work, thus ensuring the normal use and service life of the casting assembly 5. On the other hand, recovering the residual molten liquid into the recovery tank 13 allows for full utilization of the metal material, further reducing production costs.

[0027] like Figure 1 As shown, in this embodiment, specifically, the controller 7 is installed on the side of the frame 11, and the controller 7 is equipped with a control panel. The controller 7 is electrically connected to the melting tank 12, the drive assembly 2, the pusher assembly 3 and the solidification assembly 4 respectively. When using the device, the operator can set various parameters through the control panel on the controller 7, such as the heating temperature of the melting tank 12, the stirring speed of the stirring component 6, the moving speed and path of the drive component 2, the pushing time and force of the pushing component 3, and the cooling temperature and time of the solidification component 4.

[0028] Working Principle: When using this device, the mold is first installed onto the casting assembly 5. Then, the drive assembly 2 is activated, moving the casting assembly 5 below the melting tank 12. The melting tank 12 adds molten metal into the casting assembly 5, which then flows into the mold. The drive assembly 2 moves the casting assembly 5 between the solidification assembly 4 and the recovery tank 13. First, the pusher assembly 3 continues to push it to the recovery tank 13. Defective products or excess metal scrap can be directly recycled into the recovery tank 13 for subsequent reuse. Then, the pusher assembly 3 begins to work, pushing the cast mechanical seal ring out of the mold and into the solidification assembly. 4. Solidification is carried out. Solidification component 4 can accelerate the solidification process of the mechanical seal ring through cooling system and other means, thereby improving production efficiency. Throughout the casting process, the various components work closely together. The precise movement of drive component 2 ensures the accuracy of the pouring position. The orderly movement of push component 3 realizes the product push-out and recovery. The efficient cooling of solidification component 4 ensures the quality of the product. Moreover, the anti-fire function of the mold plays a key role in the entire casting process. It can effectively prevent the molten metal from escaping during the pouring process, avoiding safety accidents and product quality problems caused by fire, and improving the safety and reliability of the casting work.
