Description

Technical Field

[0001] This utility model belongs to the technical field of casting production, and in particular relates to a gating structure for casting. Background Technology

[0002] The gating system for casting is a crucial channel connecting the gating system and the mold cavity. Its main function is to guide molten metal into the cavity smoothly and evenly along a reasonable path, while also providing functions such as slag blocking, venting, and feeding. A typical gating system usually consists of a pouring cup (the inlet for receiving molten metal), a sprue (the main channel for vertically conveying molten metal), a runner (for horizontally distributing molten metal and blocking slag), and an ingate (a small channel directly connecting to the mold cavity). Through reasonable size design and layout, each part can reduce the flow resistance of molten metal, avoid slag entrapment and oxidation, and ensure complete filling and dense structure of the casting. It is one of the core factors affecting the quality of the casting.

[0003] However, it still has the following drawbacks in actual use: the existing casting gate structure is integrally formed with the mold and cannot be disassembled. This makes it difficult to clean the solidified casting material inside after demolding. At the same time, due to the overall sealing of the mold, it is impossible to accurately determine whether the casting material has filled the entire mold. During pouring, it is impossible to accurately determine whether the casting material has filled the entire mold. Utility Model Content

[0004] The purpose of this utility model is to provide a gating structure for casting, which solves the problem of the gating being unable to be disassembled and inconvenient to clean in the existing solution by setting the main components.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a gating structure for casting, including a main component and an overflow warning component. The main component includes a base, and an external threaded tube is fixed on the upper surface of the center of the base. An insertion groove is opened on the peripheral side wall of the external threaded tube.

[0007] The main component also includes a sprue body, one end of which is fixed with a hopper, and a limiting component is fixed on the outer periphery of the end of the sprue body away from the hopper. When the sprue body is inserted into the bottom component, the limiting component is inserted into the insertion groove. An internal threaded tube is movably connected to the outer periphery of the sprue body, and the internal threaded tube and the external threaded tube are threaded together.

[0008] Furthermore, the main component also includes a handle, which is horizontally fixed to the outer periphery of the internally threaded tube.

[0009] Furthermore, the outer diameter of the limiting component is larger than the outer diameter of the internally threaded pipe.

[0010] Furthermore, the overflow warning component includes a connecting pipe that runs through the outer periphery of the main body of the gating system. A central component is connected to the end of the connecting pipe that is away from the main body of the gating system. A movable plate is vertically and movably connected to the inner cavity of the central component. A warning rod is fixed to the center of the upper surface of the movable plate. The end of the warning rod that is away from the movable plate protrudes from the central component.

[0011] Furthermore, a protrusion is fixed on the inner peripheral sidewall of the central component, and a corresponding groove is provided on the movable plate.

[0012] Furthermore, the central component is set perpendicular to the main body of the gating system.

[0013] This utility model has the following beneficial effects:

[0014] 1. The present invention, through the main component, allows for the alignment of the main body of the gating system with the inner side of the external threaded pipe during use. This aligns the limiting member on the outer periphery of the gating system with the insertion groove on the side wall of the external threaded pipe. The gating system is then slowly inserted until the limiting member is fully engaged in the insertion groove. At this point, the handle on the outer periphery of the internal threaded pipe is rotated to screw the internal threaded pipe and the external threaded pipe together until they are tightly connected, thus completing the assembly of the main component. This solves the problem of the gating system being unable to be disassembled and inconvenient to clean in the existing solution.

[0015] 2. This utility model, through the addition of an overflow warning component, ensures that when the molten metal level in the main body of the sprue is too high, the excess molten metal will flow into the central component through the connecting pipe, causing the movable plate to move upward. The warning rod on the movable plate will then rise, with its top protruding outside the central component. Operators can observe the protruding length of the warning rod to determine whether overflow has occurred and stop adding material in time to avoid waste or mold damage. This solves the problem of existing sprues being unable to accurately determine whether the molten material has filled the entire mold due to the overall sealing of the mold, which easily leads to overflow.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-5 As shown, this utility model is a gating structure for casting, including a main component 1 and an overflow warning component 2. The main component 1 includes a base 11, and an external threaded tube 12 is fixed on the upper surface of the center of the base 11. An insertion groove 13 is provided on the side wall of the external threaded tube 12. The main component 1 mainly consists of the gating body 14 and the base 11 for its installation. Traditional gatings are directly welded or integrally formed on the casting mold and cannot be removed, making it inconvenient to clean the gating.

[0026] The main component 1 also includes a sprue body 14, with a hopper 15 fixedly connected to one end of the sprue body 14. A limiting member 16 is fixed to the outer periphery of the end of the sprue body 14 away from the hopper 15. When the sprue body 14 is inserted into the bottom component 11, the limiting member 16 is inserted into the insertion groove 13. An internal threaded tube 17 is movably connected to the outer periphery of the sprue body 14. The internal threaded tube 17 and the external threaded tube 12 are threadedly connected. The hopper 15 facilitates the injection of molten metal. The limiting member 16 is used to make the sprue body 14 and the bottom component 11 fit tightly together. The external threaded tube 12 is pressed down to provide a fixed force.

[0027] Furthermore, the main component 1 also includes a handle 18, which is horizontally fixed to the outer periphery of the internally threaded tube 17. The handle 18 facilitates the operator to quickly rotate the internally threaded tube 17, thereby improving assembly efficiency.

[0028] Furthermore, the outer diameter of the limiting member 16 is larger than the outer diameter of the internal threaded tube 17, which allows the internal threaded tube 17 to always tightly press against the limiting member 16, so that the gating body 14 and the bottom member 11 fit together tightly.

[0029] Furthermore, the overflow warning component 2 includes a connecting pipe 21 that passes through and connects to the outer periphery of the gating body 14. A central component 22 is connected to the end of the connecting pipe 21 that is away from the gating body 14. A movable plate 23 is vertically and movably connected to the inner cavity of the central component 22. A warning rod 25 is fixed at the center of the upper surface of the movable plate 23. The end of the warning rod 25 that is away from the movable plate 23 protrudes from the central component 22.

[0030] The overflow warning component 2 is mainly used to facilitate observation after the mold is filled and overflows, preventing waste of injection material and potential safety hazards. It mainly utilizes the principle of communicating vessels.

[0031] Furthermore, a protrusion 24 is fixed on the inner peripheral sidewall of the central component 22, and a corresponding groove is provided on the movable plate 23. The protrusion 24 on the inner sidewall of the central component 22 cooperates with the groove of the movable plate 23 to restrict the lateral displacement of the movable plate 23, ensuring that it only moves along the axial direction and preventing displacement due to insufficient precision of the parts.

[0032] Furthermore, the center component 22 is arranged perpendicularly to the gating body 14.

[0033] The specific working principle of this utility model is as follows: When using this device, fix the bottom part 11 to the corresponding position of the casting mold to ensure that the external threaded tube 12 is vertically upward. Then, hold the main body of the gating system 14 and align the end away from the hopper 15 with the inner side of the external threaded tube 12 so that the limiting part 16 on the outer periphery of the gating system 14 is aligned with the insertion groove 13 on the side wall of the external threaded tube 12. Slowly insert it until the limiting part 16 is completely inserted into the insertion groove 13. At this time, rotate the handle 18 on the outer periphery of the internal threaded tube 17 so that the internal threaded tube 17 and the external threaded tube 12 are threaded together until the two are tightly connected, thus completing the assembly of the main body component 1.

[0034] After assembly, molten metal is poured from hopper 15. The molten metal flows along the main body 14 of the sprue and is injected into the mold cavity. Due to the cooperation between the limiting part 16 and the insertion slot 13, there is no relative rotation between the main body 14 of the sprue and the bottom part 11, ensuring stable delivery of the molten metal. The overflow warning component 2 is connected to the main body 14 of the sprue through the connecting pipe 21. The center part 22 is set vertically to the connecting pipe 21. The movable plate 23 inside it can slide in the vertical direction. The protrusion 24 on the inner side wall of the center part 22 cooperates with the groove of the movable plate 23 to limit the lateral displacement of the movable plate 23 and ensure that it only moves in the axial direction. When the molten metal level in the main body 14 is too high, the excess molten metal will flow into the center part 22 through the connecting pipe 21, squeezing the movable plate 23 to move upward. The warning rod 25 on the movable plate 23 will rise accordingly, with its top protruding outside the center part 22. The operator can judge whether overflow has occurred by observing the protruding length of the warning rod 25 and stop feeding in time to avoid waste or damage to the mold.

[0035] After casting is completed, turn the handle 18 in the opposite direction to separate the internal threaded tube 17 from the external threaded tube 12, and the main body of the gating system 14 can be pulled out from the bottom part 11. At this time, the limiting part 16 is disengaged from the insertion groove 13, which makes it easy to clean or replace parts of the main body of the gating system 14, the hopper 15 and the overflow warning component 2. The metal remaining inside can be destroyed by external force.

[0036] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
