Description

Technical Field

[0001] This application relates to the field of casting technology, specifically to a slag-blocking pouring cup. Background Technology

[0002] In the casting process, slag inclusions are easily left in the molten metal due to the influence of raw materials and the melting environment. The pouring cup is a key component of the casting gating system, primarily used to receive the molten metal poured from the ladle. During the casting process, the molten metal is poured into the pouring cup, and then flows through the gating system from the bottom of the cup to the mold cavity. The molten metal cools and solidifies within the mold cavity to obtain a casting of the predetermined shape and size.

[0003] In related technologies, the slag-blocking effect of the pouring cup is poor, making it difficult to effectively filter slag inclusions in the molten metal, which causes the slag inclusions to be carried into the mold cavity, thus affecting the quality of the casting. Utility Model Content

[0004] The purpose of this application is to provide a slag-blocking pouring cup to solve the problem of poor slag-blocking effect of the pouring cup, which affects the quality of the casting.

[0005] To achieve the objectives of this application, the following technical solution is provided:

[0006] Firstly, this application provides a slag-blocking pouring cup, comprising:

[0007] The cup body is equipped with a pouring hole and a cavity for containing molten metal;

[0008] A first baffle and a second baffle are both connected to the cup body and divide the cavity into a first chamber, a second chamber and a third chamber. The first baffle has a first channel connecting the first chamber and the second chamber, and the second baffle has a second channel connecting the second chamber and the third chamber. The pouring hole is connected to the first chamber.

[0009] A first partition is disposed in the first channel, the first partition can isolate the first channel, and the first partition is configured to melt when the molten metal is poured to a preset height of the second chamber, so that the first chamber and the second chamber are connected.

[0010] A second partition is disposed in the second channel, which can isolate the second channel. The second partition is configured to melt when the molten metal is poured to a preset height in the third chamber, so that the second chamber communicates with the third chamber.

[0011] In one embodiment, the first partition includes a first conduit and a first partition. The first conduit is connected to the inner wall of the first channel, and the first partition is connected to the first conduit. When the molten metal is poured to a preset height in the second chamber, the first partition melts.

[0012] In one embodiment, multiple first conduits are provided, and a first septum is connected between two adjacent first conduits.

[0013] In one embodiment, the first partition is provided with a first guiding melting hole, which extends axially along the first conduit.

[0014] In one embodiment, the second partition includes a second conduit and a second partition, the second conduit being connected to the inner wall of the second channel, and the second partition being connected to the second conduit. When the molten metal is poured to a preset height in the third chamber, the second partition melts.

[0015] The second partition is provided with a second guiding melting hole, which extends along the axial direction of the second conduit.

[0016] In one embodiment, the cup body includes a cup bottom and a side rim surrounding the cup bottom. The cup bottom and the side rim are connected to form the cavity. The first baffle and the second baffle are both connected to the side rim to divide the cavity into a first chamber, a second chamber, and a third chamber.

[0017] In one embodiment, the cup bottom located in the second chamber includes a first bottom surface, a second bottom surface, and a flow guiding surface. The first bottom surface is located in the middle of the second chamber, and the second bottom surface is located at both ends of the second chamber. The height of the first bottom surface is lower than the height of the second bottom surface. The flow guiding surface is connected between the first bottom surface and the second bottom surface, and the first baffle is connected to the first bottom surface.

[0018] In one embodiment, a first recess is provided on the first bottom surface, a second recess is provided on a portion of the bottom surface of the first chamber, the pouring hole is provided on another portion of the bottom surface of the first chamber, and the first baffle is connected between the first recess and the second recess.

[0019] In the orthographic projection of the first channel along its axial direction, at least a portion of the first channel lies within the first recess and the second recess.

[0020] In one embodiment, the slag-blocking pouring cup further includes a third partition, which is disposed in the pouring hole. The third partition includes a third guide tube and a third partition plate. The third guide tube is connected to the wall of the pouring hole, and the third partition plate is connected to the third guide tube. When the molten metal is poured to a preset height in the first chamber, the third partition plate melts.

[0021] In one embodiment, two third conduits are provided, wherein the inner diameter of one third conduit is smaller than the inner diameter of the other third conduit, so as to form a stepped surface at the junction of the two third conduits, and the third spacer abuts against the stepped surface;

[0022] The third partition is provided with a third guiding melting hole, which extends along the axial direction of the third conduit.

[0023] Compared with the prior art, this application has at least the following beneficial effects:

[0024] 1. In this application, the cavity of the cup body is divided into a first chamber, a second chamber, and a third chamber by a first baffle and a second baffle. The pouring hole is used to communicate with the gating system and is also connected to the first chamber. The molten metal is first poured into the third chamber. At this time, the second partition closes the second channel, and the molten metal remains stationary in the third chamber. Surface impurities float and accumulate above the molten metal due to the stagnant flow. When the liquid level rises to a preset height, the molten metal fully contacts the second partition and transfers heat. After the second partition melts due to heat, the second channel opens, and the molten metal, after impurity separation, flows into the second chamber through the second channel. When the molten metal in the second chamber has not reached the preset height, the second chamber can filter the incoming molten metal again to remove residual impurities. When the liquid level rises to the preset height, the molten metal fully contacts the first partition and transfers heat. After the first partition melts due to heat, the first channel opens. The molten metal, after impurity separation, flows into the first chamber through the first channel and finally enters the gating through the pouring hole. This avoids the high-speed flowing molten metal disturbing the impurity layer, reduces the amount of impurities in the molten metal entering the gating, and thus improves the quality of the casting.

[0025] 2. In this application, the multi-stage separation of the first baffle and the second baffle enables the phased flow of the metal solution, which can more effectively remove impurities from the metal solution and improve the purity of the metal solution.

[0026] 3. In this application, the first and second partitions can control the connectivity of the channels based on the height of the molten metal in the corresponding chambers, thereby precisely controlling the timing and flow rate of the molten metal between different chambers. This helps prevent the molten metal from flowing into subsequent chambers too quickly or too slowly, ensuring that each chamber can fully perform its slag-blocking and purification functions, making the entire casting process more stable and controllable.

[0038] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0039] refer to Figures 1-4 This application provides a slag-blocking pouring cup, including a cup body 100, a first baffle 200, a second baffle 300, a first partition 400, and a second partition 500.

[0040] The cup body 100 is provided with a pouring hole 110 and a cavity 120 for containing molten metal. The cup body 100 is the main structure with the function of containing molten metal. It can be made of resin sand or refractory material. Its internal cavity 120 is used to temporarily store and guide molten metal. The molten metal in the cavity 120 is transported to the gating channel through the pouring hole 110.

[0041] The first baffle 200 and the second baffle 300 are both connected to the cup body 100 and divide the cavity 120 into a first chamber 121, a second chamber 122, and a third chamber 123. The first baffle 200 has a first channel 210 connecting the first chamber 121 and the second chamber 122, and the second baffle 300 has a second channel 310 connecting the second chamber 122 and the third chamber 123. The pouring hole 110 is connected to the first chamber 121. The first baffle 200 and the second baffle 300 are components that divide a single cavity 120 into multiple independent chambers. Specifically, the first baffle 200 and the second baffle 300 can be sand mold structures integrally formed with the cup body 100.

[0042] A first partition 400 is disposed in the first channel 210, which can isolate the first channel 210. The first partition 400 is configured to melt when the molten metal is poured to a preset height in the second chamber 122, so that the first chamber 121 and the second chamber 122 are connected. The first partition 400 is a heat-melting barrier element. When the molten metal level in the second chamber 122 rises to the preset height, the first partition 400 has been in contact with the molten metal for a period of time, and heat conduction causes it to fail and melt. Specifically, the melting point of the material of the first partition 400 is higher than that of the molten metal.

[0043] The second partition 500 is disposed in the second channel 310, and the second partition 500 can isolate the second channel 310. The second partition 500 is configured to melt when the molten metal is poured to a preset height in the third chamber 123, so that the second chamber 122 and the third chamber 123 are connected. The second partition 500 is also a heat-melting barrier element. When the molten metal level in the third chamber 123 rises to the preset height, the second partition 500 has been in contact with the molten metal for a period of time, and heat conduction causes it to fail and melt. The second partition 500 can be made of the same material as the first partition 400.

[0044] Specifically, the molten metal is first injected into the third chamber 123. At this time, the second partition 500 closes the second channel 310, and the molten metal is temporarily stored in the third chamber 123 for initial settling. Due to its low impurity density, the impurities float to the top of the molten metal. When the liquid level rises to the preset height of the third chamber 123, the second partition 500 melts upon heating, and the molten metal flows into the second chamber 122 through the second channel 310 for secondary settling. The first partition 400 remains closed in the second chamber 122 until the molten metal reaches the preset height, forcing the molten metal to remain in the second chamber 122. When the liquid level of the molten metal in the second chamber 122 reaches the preset height, the first partition 400 melts, and the purified molten metal enters the first chamber 121, and finally enters the mold cavity through the pouring hole 110. The multi-stage separation by the first baffle 200 and the second baffle 300 enables the phased flow of the molten metal, which can more effectively remove impurities from the molten metal, improve the purity of the molten metal, and thus improve the quality of the castings.

[0045] In this application, the first partition 400 can precisely control the timing of the connection between the first chamber 121 and the second chamber 122, and the second partition 500 can precisely control the timing of the connection between the second chamber 122 and the third chamber 123. This avoids the first channel 210 and the second channel 310 opening too early, which could lead to the introduction of impurities, or the first channel 210 and the second channel 310 opening too late, which could affect the continuity of pouring. Furthermore, the third chamber 123 can accommodate the movement or fixed addition of liquid to multiple ladles, improving work efficiency. The first baffle 200 and the second baffle 300 prevent the molten metal from directly flowing into the first chamber 121 and into the pouring hole 110. The first baffle 200 and the second baffle 300 have a blocking effect, facilitating the floating of impurities and ensuring a steady flow of the molten metal into the pouring hole 110, preventing the introduction of impurities and air.

[0046] The first partition 400 includes a first conduit 410 and a first partition 420. The first conduit 410 is connected to the inner wall of the first channel 210, and the first partition 420 is connected to the first conduit 410. When the molten metal is poured to a preset height in the second chamber 122, the first partition 420 melts. The first conduit 410 is a tubular structure disposed within the first channel 210, and can be made of a high-temperature resistant ceramic material, used to support the first partition 420 and guide the flow direction of the molten metal. The first partition 420 is a sheet-like structure that closes the channel, and can be made of a material with a melting point higher than that of the molten metal. When the molten metal level in the second chamber 122 reaches a preset height, the heat generated melts the first partition 420, thereby achieving communication between the first chamber 121 and the second chamber 122.

[0047] Specifically, when the molten metal enters the second chamber 122, the molten metal just comes into contact with the first partition 420, insufficient to melt the first partition 420. The first partition 420 temporarily closes the first channel 210, preventing the solution from flowing into the first chamber 121. As the molten metal level in the second chamber 122 rises to a preset height, the molten metal has been in contact with the first partition 420 for a period of time, causing the first partition 420 to melt due to heat. At this time, the first channel 210 is opened, and the molten metal in the second chamber 122 flows into the first chamber 121 through the first conduit 410, and then enters the gating system through the pouring hole 110. During this process, the first conduit 410 constrains the flow path of the solution, while the delayed opening characteristic of the first partition 420 allows impurities in the second chamber 122 to float sufficiently to the surface.

[0048] It should be noted that the first channel 210 is located near the bottom of the first baffle 200. Impurities in the molten metal float to the top and enter the first chamber 121 after being separated from the impurities through the first channel 210 at the bottom. This effectively reduces the probability of impurities entering the mold cavity, thereby improving the quality of the casting.

[0049] refer to Figure 1 , Figure 5 and Figure 6 Multiple first conduits 410 are provided, and a first partition 420 is connected between two adjacent first conduits 410. The combination structure of multiple first conduits 410 and partitions can form a multi-stage static mechanism. The number of first conduits 410 and first partitions 420 can be adjusted according to the amount of metal solution to be poured, thereby precisely controlling the timing of the connection between the first chamber 121 and the second chamber 122.

[0050] The first partition 420 is provided with a first guiding melting hole 421, which extends along the axial direction of the first conduit 410. The first guiding melting hole 421 can be a through hole, specifically a circular, square, or elliptical hole, and its function is to guide the molten metal to contact and accelerate the melting of the first partition 420.

[0051] refer to Figure 1 and Figure 7 The second partition 500 includes a second conduit 510 and a second partition 520. The second conduit 510 is connected to the inner wall of the second channel 310, and the second partition 520 is connected to the second conduit 510. When the molten metal is poured to a preset height in the third chamber 123, the second partition 520 melts. The second partition 520 is provided with a second guiding melting hole 521, which extends axially along the second conduit 510. The second conduit 510 is a tubular structure fixed inside the second channel 310 to support the partition. When the molten metal level in the third chamber 123 reaches a preset height, the second partition 520 melts due to heat.

[0052] Specifically, when the molten metal is poured into the third chamber 123 from the ladle, the liquid level gradually rises to a preset height. At this time, the second partition 520 fails and melts due to the heat conduction of the high-temperature molten metal. The presence of the second guiding melting hole 521 allows the heat to be more concentrated on the weak area of ​​the partition. As the temperature continues to rise, the second partition 520 first melts through around the second guiding hole, forming a through gap. Subsequently, the entire second partition 520 completely melts and disappears, thereby opening the second channel 310. The structure of the second guiding melting hole 521 simplifies the triggering conditions for the melting of the second partition 520, reduces the sensitivity to ambient temperature, and makes the slag-blocking effect during the pouring process more stable and reliable.

[0053] In this embodiment, the cup body 100 includes a cup bottom 130 and a side circumference 140 surrounding the cup bottom 130. The cup bottom 130 and the side circumference 140 are connected to form a cavity 120. A first baffle 200 and a second baffle 300 are both connected to the side circumference 140 to divide the cavity 120 into a first chamber 121, a second chamber 122, and a third chamber 123. The cup bottom 130 is a planar or curved structure used to hold the molten metal, and the side circumference 140 is a vertical or inclined wall structure surrounding the cup bottom 130 to limit the lateral diffusion of the molten metal within the cavity 120.

[0054] Specifically, the cup bottom 130 and the side wall 140 are vertically connected to form a closed cavity 120 structure. The first baffle 200 and the second baffle 300 extend along the height direction of the side wall 140 and are fixed to the inner wall of the side wall 140, thereby dividing the single cavity 120 into three or more independent chambers. When the molten metal flows through the third chamber 123, the second chamber 122 and the first chamber 121 in sequence, the inclusions are intercepted step by step in the flow path between the multiple chambers, which prolongs the flow path of the molten metal and reduces the amount of inclusions entering the pouring hole 110, thereby reducing the risk of defects in the casting caused by inclusions.

[0055] The cup bottom 130 located in the second chamber 122 includes a first bottom surface 131, a second bottom surface 132, and a flow guiding surface 133. The first bottom surface 131 is located in the middle of the second chamber 122, and the second bottom surface 132 is located at both ends of the second chamber 122. The height of the first bottom surface 131 is lower than the height of the second bottom surface 132. The flow guiding surface 133 connects the first bottom surface 131 and the second bottom surface 132. A first baffle 200 is connected to the first bottom surface 131. The first bottom surface 131 is a planar structure located in the middle of the second chamber 122 with a relatively low height. Specifically, it can be implemented using a downwardly concave arc-shaped or stepped structure to form a convergence area for the molten metal. The second bottom surface 132 is a planar structure located at both ends of the second chamber 122 with a relatively high height. Specifically, it can be implemented using a horizontally extending flat plate structure. The flow guiding surface 133 is an inclined transition surface connecting the first bottom surface 131 and the second bottom surface 132. Specifically, it can be implemented by using an inclined surface or a curved surface structure to guide the metal solution from the second bottom surface 132 to the first bottom surface 131.

[0056] When the molten metal is injected into the second chamber 122, because the second bottom surface 132 is higher than the first bottom surface 131, the solution flows towards the first bottom surface 131 along the guide surface 133 under the influence of gravity, forming a stable liquid surface gradient. The low-lying structure of the first bottom surface 131 causes the molten metal to converge in the middle of the second chamber 122, reducing turbulence or eddies generated during the flow. The first baffle 200 is connected to the first bottom surface 131, allowing the molten metal in the second chamber 122 to flow out through the first channel 210 on the first baffle 200.

[0057] refer to Figure 2 , Figure 3 and Figure 4 A first recess 131a is provided on the first bottom surface 131, and a second recess 121a is provided on a portion of the bottom surface of the first chamber 121. A pouring hole 110 is provided on another portion of the bottom surface of the first chamber 121. A first baffle 200 is connected between the first recess 131a and the second recess 121a. In the axial orthogonal projection of the first channel 210, at least a portion of the first channel 210 is located within the first recess 131a and the second recess 121a. The first recess 131a is a downwardly recessed structure located in the central region of the bottom of the second chamber 122. Specifically, it can be implemented as an arc-shaped groove or a stepped groove, which is used to increase the flow path length of the metal solution in the second chamber 122 and promote the floating of impurities. The second recess 121a is a recessed area located at the bottom of the first chamber 121 near the second chamber 122. Specifically, it can be implemented using a groove structure symmetrical to the first recess 131a. It is used to guide the molten metal from the first channel 210 into the first chamber 121 to form a directional flow and reduce turbulence.

[0058] Specifically, when the molten metal flows from the second chamber 122 into the first chamber 121 through the first channel 210, the first recess 131a guides the molten metal to flow towards the first baffle 200. The drop structure formed by the first recess 131a and the second recess 121a extends the path of the solution into the first chamber 121. When the molten metal flows through the first channel 210, since the orthogonal projection of the first channel 210 along the axial direction covers the recessed area, the flow direction is restricted to extending along the contours of the first recess 131a and the second recess 121a, avoiding direct impact of the molten metal on the edge of the first baffle 200 and reducing turbulence.

[0059] refer to Figure 3 and Figure 8 The slag-blocking pouring cup also includes a third partition 600, which is disposed in the pouring hole 110. The third partition 600 includes a third conduit 610 and a third partition 620. The third conduit 610 is connected to the wall of the pouring hole 110, and the third partition 620 is connected to the third conduit 610. When the molten metal is poured to a preset height in the first chamber 121, the third partition 620 melts. The third partition 600 is a fusible structure installed in the pouring hole 110 to temporarily seal the pouring hole 110.

[0060] Specifically, the fusible third partition 600 replaces manual plugging, reducing safety hazards. The third partition 600 controls the flow path of the molten metal in stages. In the initial stage when the molten metal enters the first chamber 121, it blocks the pouring hole 110, forcing the molten metal to remain within the first chamber 121. When the molten metal accumulates to a preset height in the first chamber 121, the third partition 620 melts due to heat reaching its melting point, opening the pouring hole 110 and allowing the molten metal to flow steadily into the runner. This process delays the opening time of the pouring hole 110, ensuring that impurities float to the surface within the first chamber 121, further reducing eddy currents in the initial pouring stage. Simultaneously, the combined structure of the third guide tube 610 and the third partition 620 precisely controls the opening timing of the pouring hole 110, preventing secondary slag inclusion due to premature or delayed opening, significantly improving the slag-blocking efficiency of the pouring cup.

[0061] In one embodiment, two third conduits 610 are provided, one of which has a smaller inner diameter than the other, forming a stepped surface at the junction of the two third conduits 610. A third spacer 620 abuts against the stepped surface. The third spacer 620 is provided with a third guiding melting hole 621, which extends axially along the third conduit 610. Specifically, the third partition 600 forms a stepped surface through the two third conduits 610 with different inner diameters, so that the third spacer 620 is stably fixed in the pouring hole 110. When the molten metal is injected into the first chamber 121 and reaches a preset height, the molten metal rapidly transfers heat through the third guiding melting hole 621, causing the third spacer 620 to fail and melt. At this time, the pouring hole 110 is opened, and the molten metal flows into the gating system through the third conduit 610. The presence of the stepped surface ensures that the partition remains sealed before it melts, preventing premature leakage and effectively preventing the molten metal from flowing into the gating system before reaching the preset height. This reduces the risk of slag inclusions entering the casting cavity and improves the quality of the finished casting.
