They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0032] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0033] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0034] As attached Figure 2As shown, in order to facilitate understanding of the positional relationship and connection relationship of the various components in the utility model, the direction along the X-axis is defined as the first direction, the direction along the Y-axis is defined as the second direction, and the direction along the Z-axis is defined as the third direction. The first direction, the second direction and the third direction are perpendicular to each other. The following along the first, second or third direction only indicates a rough direction relationship, and does not mean that it needs to be strictly parallel. There may be a certain degree of angular deviation. Technical personnel in this field can adjust the direction according to actual needs.

[0035] As attached Figure 1 As shown, the split flow splitter cone proposed by the utility model includes a shell 10 and a core 20, the shell 10 and the core 20 are sealed and connected along a first direction, and the shell 10 and the core 20 are sealed and connected along a first direction. Figure 2 The shell 10 includes a receiving cavity 11 , which is opened along a first direction and is a cavity structure with one end open. The receiving cavity 11 cooperates with the core 20 so that the core 20 can be installed in the receiving cavity 11 .

[0036] As attached Figure 5 As shown, the core 20 includes a first functional surface 201, a second functional surface 202, a third functional surface 203 and a fourth functional surface 204. The first functional surface 201 is located on one side of the core 20 along the third direction, the second functional surface 202 and the third functional surface 203 are located on both sides of the core 20 along the second direction, the second functional surface 202 is opposite to the third functional surface 203, the second functional surface 202 and the third functional surface 203 are respectively connected to the first functional surface 201, and are located in different planes with the first functional surface 201, the fourth functional surface 204 is located on one side of the core 20 along the first direction, and on the side of the core 20 close to the shell 10, and the fourth functional surface 204 is respectively connected to the first functional surface 201, the second functional surface 202 and the third functional surface 203.

[0037] For ease of understanding, the first functional surface 201 is a side surface of the core 20 with a relatively larger area, the second functional surface 202 and the third functional surface 203 are side surfaces of the core 20 with a relatively smaller area, and the fourth functional surface 204 is the bottom surface of the core 20. When the core 20 is connected to the shell 10, the fourth functional surface 204 is the surface that first enters the accommodating cavity 11.

[0038] As attached Figure 5As shown, the core 20 includes at least one concave channel 205, which is opened on the first functional surface 201 and can extend to at least one of the second functional surface 202, the third functional surface 203 and the fourth functional surface 204. The core 20 is used to connect the external coolant pipeline and the channel 205. The channel 205 cooperates with the cavity wall of the accommodating cavity 11 to form a flow channel for the coolant. The external coolant enters the accommodating cavity 11 through the coolant pipeline, flows between the channel 205 and the cavity wall of the accommodating cavity 11, and forms a coolant circulation to cool the shell 10 and the core 20.

[0039] The separate arrangement of the shell 10 and the core 20 facilitates separate processing and facilitates processing of the channel 205 on the core 20. By arranging the channel 205 on different surfaces of the core 20, the contact area between the coolant and the shell 10 and the core 20 can be increased, thereby improving the cooling quality of the diverter cone, allowing the shell 10 and the core 20 to be cooled evenly, reducing the probability of fried cakes, and improving production quality.

[0040] Optionally, the shell 10 and the core 20 are connected by welding, and the connection is stable and reliable.

[0041] Optionally, the accommodating cavity 11 and the core body 20 are interference fit to facilitate positioning and connection, and enable the channel 205 to be in close contact with the cavity wall of the accommodating cavity 11 to prevent leakage of the coolant.

[0042] In one example, as shown in the attached Figure 5 As shown, the number of channels 205 is two and they are symmetrically distributed on the core 20 about the first direction. This arrangement facilitates the processing of the channels 205 and can form two coolant circulations to efficiently cool the core 20, thereby avoiding uneven cooling of different positions of the core 20 due to too long a circulation of the channels 205, and improving the cooling efficiency.

[0043] As attached Figure 5 As shown, the core 20 is provided with a first connecting hole 206 and a second connecting hole 207, and the first connecting hole 206 and the second connecting hole 207 are used to connect an external coolant pipeline, and the coolant pipeline includes an inlet pipeline and a discharge pipeline. One of the first connecting hole 206 and the second connecting hole 207 is used to connect the inlet pipeline, and the other is used to connect the discharge pipeline. The first connecting hole 206 is connected to one end of the channel 205, and the second connecting hole 207 is connected to the end of the channel 205 away from the first connecting hole 206. In this way, the coolant entering the channel 205 from the inlet pipeline can flow a large distance and then flow out from the discharge pipeline.

[0044] In one example, the first connecting hole 206 and the second connecting hole 207 are opened along the first direction and penetrate the core 20 in the first direction.

[0045] In one example, when the number of channels 205 is two, the number of first connecting holes 206 is two, the two first connecting holes 206 are symmetrically distributed on the core 20 about the first direction, and the two first connecting holes 206 are respectively connected to one end of the two channels 205, and the number of second connecting holes 207 is two, the two second connecting holes 207 are symmetrically distributed on the core 20 about the first direction, and the two second connecting holes 207 are respectively connected to one end of the two channels 205 away from the first connecting holes 206, that is, one channel 205 cooperates with one first connecting hole 206 and one second connecting hole 207 to realize the circulation of coolant.

[0046] In one example, as shown in the attached Figure 5 As shown, the first connecting hole 206 passes through the first functional surface 201 to be connected to one end of the channel 205 located on the first functional surface 201 .

[0047] In one example, as shown in the attached Figure 5 As shown, the second connecting hole 207 passes through the fourth functional surface 204 to be connected to one end of the channel 205 located on the fourth functional surface 204 .

[0048] In one example, the overall shape of the channel 205 is roughly pig brain-shaped to increase the flow distance of the coolant and improve the cooling quality.

[0049] As attached Figure 6 As shown, the channel 205 includes a first end channel 2051, a middle channel 2052 and a second end channel 2053, and the first end channel 2051 and the second end channel 2053 are connected through the middle channel 2052, wherein the first end channel 2051 is located on the first functional surface 201 and can extend to at least one of the second functional surface 202 and the third functional surface 203, the first end channel 2051 is connected to the first connecting hole 206, the middle channel 2052 is located on the first functional surface 201 and can extend to at least one of the second functional surface 202 and the third functional surface 203, the second end channel 2053 is located on the fourth functional surface 204 and can extend to at least one of the second functional surface 202 and the third functional surface 203, and the second end channel 2053 is connected to the second connecting hole 207.

[0050] As attached Figure 6 As shown, the middle channel 2052 is formed by connecting a plurality of S-shaped channels end to end in sequence in the first direction. By so configuring, the space of the core 20 can be utilized as much as possible to arrange the longer channel 205, so that the amount of coolant flowing through the unit area of ​​the core 20 is as large as possible, and the flow stroke of the coolant can be increased, thereby improving the cooling effect. The S-shaped channels are distributed along the first direction. It can be understood that each S-shaped channel includes two U-shaped loop bends 2054, and the U-shaped loop bend 2054 includes an arch and an opening. Figure 5, one of the loop bends 2054 is arched toward the direction close to the second functional surface 202, and its opening side is away from the second functional surface 202, and the other loop bend 2054 is arched toward the direction close to the third functional surface 203, and its opening side is away from the third functional surface 203. One of the loop bends 2054 can extend to the second functional surface 202, and the other loop bend 2054 can extend to the third functional surface 203.

[0051] In one example, when the number of channels 205 is set to one, the loop bend 2054 close to the second functional surface 202 extends to the second functional surface 202 , and the loop bend 2054 close to the third functional surface 203 extends to the third functional surface 203 .

[0052] In one example, when the number of channels 205 is set to two, the middle channel 2052 close to the second functional surface 202 extends to the second functional surface 202, that is, the loop bend 2054 of the middle channel 2052 close to the second functional surface 202 extends to the second functional surface 202, and the middle channel 2052 close to the third functional surface 203 extends to the third functional surface 203, that is, the loop bend 2054 of the middle channel 2052 close to the third functional surface 203 extends to the third functional surface 203.

[0053] As attached Figure 6 As shown, the first end channel 2051 includes a U-shaped loop bend 2054 and a connecting section 2055 extending along the first direction. One end of the loop bend 2054 is connected to the middle channel 2052 through the connecting section 2055, and the other end is a free end. The first connecting hole 206 is opened on the free end and communicated with the free end.

[0054] As attached Figure 6 As shown, the second end channel 2053 is roughly C-shaped, one end of which is connected to the middle channel 2052, and the other end is a free end. The second connecting hole 207 is opened at the free end and connected to the free end.

[0055] Combined with Figure 3 and attached Figure 4 The shell 10 is provided with a first opening 111 and a second opening 112. The first opening 111 and the second opening 112 are provided on one side of the accommodating cavity 11, penetrate the shell 10, and are not connected with the accommodating cavity 11. The first opening 111 and the second opening 112 are used to connect the molten metal pipeline or the mold cavity.

[0056] Optionally, the first opening 111 and the second opening 112 are both opened along the first direction.

[0057] In one example, the shell 10 and the core 20 are connected by a positioning assembly. Through the setting of the positioning assembly, the core 20 can be stably and efficiently installed in the accommodating cavity 11, which can improve the assembly efficiency and installation quality, and enable the core 20 to be installed in place at one time, eliminating the process of repeated adjustment of the assembly, saving assembly time, and preventing the phenomenon of insufficient sealing due to deviation in the installation position, avoiding leakage of coolant in the channel 205, which is beneficial to improving the connection sealing of the shell 10 and the core 20.

[0058] In one example, as shown in the attached Figure 3 As shown, the positioning assembly includes a first positioning member 113 and a second positioning member 114. The first positioning member 113 and the second positioning member 114 are protruded in the accommodating cavity 11. Figure 5 The core body 20 is provided with a first positioning groove 221 cooperating with the first positioning member 113, and a second positioning groove 222 cooperating with the second positioning member 114. When the core body 20 is connected to the shell 10, the first positioning member 113 is installed in the first positioning groove 221, and the second positioning member 114 is installed in the second positioning groove 222. Such an arrangement enables the core body 20 to be installed in place at one time without repeated fine-tuning, thus saving assembly steps.

[0059] Optionally, the first positioning member 113 is interference fit with the first positioning groove 221 , and the first positioning member 113 is clamped in the first positioning groove 221 .

[0060] Optionally, the second positioning member 114 is interference fit with the second positioning groove 222 , and the second positioning member 114 is clamped in the second positioning groove 222 .

[0061] In one example, the first positioning member 113 and the second positioning member 114 are distributed in the accommodating cavity 11 substantially along the second direction, which can prevent the core 20 from being offset in the second direction and improve the assembly quality. Figure 3 As shown, a slot 115 is formed between the first positioning member 113 and the second positioning member 114. Figure 5 A protruding structure 224 is formed between the first positioning groove 221 and the second positioning groove 222 . When the core 20 is connected to the shell 10 , the protruding structure 224 is installed in the slot 115 .

[0062] Optionally, the protruding structure 224 is interference fit with the slot 115 , and the protruding structure 224 is locked in the slot 115 .

[0063] Optionally, the first positioning member 113 and the second positioning member 114 are integrally formed with the housing 10 , which has a simple structure and is easy to process.

[0064] Optionally, the first opening 111 is formed on the first positioning member 113 , the first opening 111 is formed along the first direction and passes through the first positioning member 113 , and the second opening 112 is formed on the second positioning member 114 , the second opening 112 is formed along the first direction and passes through the second positioning member 114 .

[0065] In another example, in conjunction with Figure 3 and attached Figure 5 The positioning assembly includes a limit groove 12 and a stopper 22. The limit groove 12 is opened on the shell 10. The limit groove 12 is located at the opening side of the accommodating cavity 11 and is connected to the accommodating cavity 11. The limit groove 12 is connected to the accommodating cavity 11 along a first direction. The outer contour size of the positive projection of the limit groove 12 in the first direction is greater than the outer contour size of the positive projection of the accommodating cavity 11 in the first direction. The core 20 includes a base member 21 and a stopper 22. The base member 21 is connected to the stopper 22 along the first direction, and the stopper The outer contour dimension of the orthographic projection of 22 in the first direction is larger than the outer contour dimension of the orthographic projection of the base member 21 in the first direction. When the core 20 is connected to the shell 10, the base member 21 is installed in the accommodating cavity 11, and the stop member 22 is installed in the limiting groove 12. In this way, through the cooperation between the limiting groove 12 and the stop member 22, and in cooperation with the first positioning member 113 and the second positioning member 114, the core 20 can be installed in place with the shell 10 at one time, so as to improve the assembly quality and the sealing of the assembly.

[0066] Optionally, the base member 21 and the stop member 22 are integrally formed to facilitate processing.

[0067] In one example, as shown in the attached Figure 2 As shown, the core 20 and the shell 10 are sealed by a sealing assembly 30, and the sealing assembly 30 is sandwiched between the shell 10 and the core 20. Figure 3 The shell 10 includes a first sealing groove 13, which is opened between the accommodating cavity 11 and the limiting groove 12. The first sealing groove 13 is used to install a sealing component 30. When the core 20 is connected to the shell 10, the sealing component 30 is sleeved on the base member 21 and pressed into the first sealing groove 13 through the stop member 22.

[0068] The sealing component 30 cooperates with the positioning component to achieve a sealed connection between the core 20 and the shell 10, further improving the sealing performance and preventing leakage of the coolant. The sealing component 30 cooperates with the stopper 22 to play a good sealing role. The setting of the stopper 22 can ensure the stable installation of the sealing component 30 and prevent the sealing component 30 from falling out, thereby ensuring the overall sealing quality. Even if some coolant flows out of the channel 205 to other positions of the accommodating cavity 11, the sealing component 30 can prevent the coolant from overflowing. If the sealing component 30 fails, the stopper 22 can still perform secondary sealing, thereby improving the sealing quality.

[0069] In one example, as shown in the attached Figure 6 As shown, a second sealing groove 223 is formed at one end of the stopper 22 close to the base member 21 , and the second sealing groove 223 is used to install the sealing assembly 30 . When the core 20 is connected to the shell 10 , the sealing assembly 30 is sleeved on the base member 21 and pressed into the second sealing groove 223 by the stopper 22 .

[0070] Optionally, the second sealing groove 223 is in communication with the first positioning groove 221 and the second positioning groove 222 .

[0071] Optionally, the sealing component 30 adopts a rubber ring.

[0072] Optionally, the number of sealing assemblies 30 is set to at least one, and the number of first sealing grooves 13 and / or second sealing grooves 223 is the same as the number of sealing assemblies 30. In this example, the number of sealing assemblies 30 is set to two, and the two sealing assemblies 30 are distributed along the first direction to perform a double sealing function to prevent coolant leakage.

[0073] Optionally, the sealing component 30 is configured to be contoured with the base member 21 , that is, the orthographic projection of the sealing component 30 in the first direction is the same as or proportionally reduced to the orthographic projection of the base member 21 in the first direction.

[0074] The split-type diverter cone of the utility model can transform the diverter cone from an integral part into an assembleable split part by separately providing a shell 10 and a core 20, thereby reducing the difficulty and cost of processing and manufacturing, and facilitating processing of the channel 205 on the core 20, connecting the shell 10 and the core 20, and sealing the shell 10 and the core 20; at least one concave channel 205 is provided on the first functional surface 201 to cooperate with the accommodating cavity 11 to circulate the cooling liquid, and the cooling liquid circulates in the channel 205 to achieve cooling of the shell 10 and the core 20; by extending the channel 205 to other surfaces connected to the first functional surface 201, the core 20 can be cooled over a larger area to improve the uniformity of cooling, improve the cooling capacity and cooling quality of the diverter cone, and reduce the temperature of the diverter cone to a temperature range that meets the metal liquid processing, thereby extending the overall service life.
