[0024] First embodiment

[0025] See also Figure 1 to Figure 3 The present invention provides a splitter cone, including a cone 101 and a mounting sleeve 102. The cone 101 is detachably connected to the mounting sleeve 102 and is located on one side of the mounting platform.

[0026] In this embodiment, the present invention introduces a specially designed splitter cone, which is used in industrial applications to optimize the flow path and efficiency of fluids or gases. The splitter cone consists of two main parts: a cone 101 and a mounting sleeve 102, and the two components are connected together in a detachable manner so that they can be easily separated when necessary for maintenance, replacement or adjustment.

[0027] The cone 101 has a thread 103 , and the mounting sleeve 102 is provided with a mounting hole 105 corresponding to the thread 103 .

[0028] The cone 101 is provided with a thread 103 structure, which not only increases the friction force of the contact surface with the fluid or gas, helps to stabilize the fluid flow, but also facilitates the connection between it and the mounting sleeve 102. The mounting sleeve 102 provides a stable support platform for the cone 101, and it is provided with a mounting hole 105 inside that matches the thread 103 of the cone 101 to ensure that the two can fit tightly.

[0029] The cone 101 is made of tungsten steel.

[0030] The cone 101 part is made of high-strength and wear-resistant tungsten steel material. This material selection ensures that the cone 101 can maintain its shape and functional characteristics under extreme working conditions, thereby extending its service life and reducing maintenance frequency.

[0031] The cone 101 has a first conical surface 106 , and the mounting sleeve 102 has a second conical surface 107 . The first conical surface 106 and the second conical surface 107 are smoothly transitioned.

[0032] The outer surface of the cone 101 forms a first conical surface 106, and the inner side of the mounting sleeve 102 is correspondingly designed with a second conical surface 107, and a smooth transition is achieved between the two conical surfaces, which helps to ensure that the fluid or gas can pass more smoothly, and also helps to disperse the pressure and avoid local stress concentration.

[0033] The mounting sleeve 102 has a plurality of exhaust grooves 108 , and the plurality of exhaust grooves 108 are distributed around the mounting sleeve 102 .

[0034] In order to further improve the working performance of the diverter cone, a plurality of exhaust grooves 108 are arranged around the mounting sleeve 102. The function of these exhaust grooves 108 is to timely discharge the air or other gases that may accumulate during the diverting process to prevent the formation of bubbles that affect the normal flow of the fluid.

[0035] The mounting sleeve 102 has a cooling groove 109 , and the cooling groove 109 is arranged on a side of the mounting sleeve 102 away from the cone 101 .

[0036] A cooling groove 109 is also provided on the side of the mounting sleeve 102 away from the cone 101. This design is particularly important for applications requiring high temperature working environments. The cooling groove 109 can help quickly remove heat and maintain the optimal working temperature of the equipment, thereby improving the reliability and safety of the overall system.

[0037] In summary, the design of this splitter cone takes into account various requirements in practical applications, including but not limited to material selection, structural strength, fluid dynamics, and thermal management, aiming to provide an efficient, durable and easy-to-maintain solution.

[0038] Second embodiment

[0039] See also Figure 4 The present invention also provides a wheel hub mold, including a diverter cone, a bottom mold, a top mold, a plurality of side molds 203 and a limiting frame 204, wherein the bottom mold is arranged at the bottom of the limiting frame 204, the top mold is arranged at the top of the limiting frame 204, a plurality of side molds 203 are slidably arranged around the limiting frame 204, and the diverter cone is installed on the top mold.

[0040] In this embodiment, the diverter cone is installed on the top mold, which is responsible for evenly distributing the injected material to all parts of the mold to ensure the uniform quality of the finished wheel hub. The bottom mold is located at the bottom of the limiting frame 204, and as the basic structure of the entire mold, it provides stable support, while the liquid metal enters the interior from the bottom mold. Several side molds 203 are slidably arranged around the limiting frame 204, and their positions can be adjusted as needed to meet the production requirements of wheels of different sizes or shapes. The limiting frame 204 serves as the outer frame of the entire mold. It not only provides a fixed mounting platform for other components, but also ensures the overall rigidity and stability of the mold when it is working.

[0041] During operation, the four side molds 203 are first pushed inward, while the top mold is moved downward to form a molding cavity of the hub. The liquid metal then enters the interior through the bottom mold and is diverted by the diverter cone. The pressure is then maintained for a period of time to allow the liquid metal to cool and form, thereby obtaining a finished hub product.

[0042] The bottom mold includes a bottom mold body 205 , a pouring cup 206 is arranged at the center of the bottom mold body 205 , and a filter screen 207 is arranged at the connection between the pouring cup 206 and the top mold.

[0043] A pouring cup 206 is provided at the center of the bottom mold body 205, which is the entry point for the material to enter the mold interior. A filter screen 207 is provided at the connection between the pouring cup 206 and the top mold to remove impurities in the material and ensure that the finished product surface is smooth and flawless.

[0044] The top mold includes a top mold body 208, an assembly hole 209 is arranged at the center of the top body, the assembly hole 209 is used to install the diverter cone, and a top rod 211 is arranged above the top mold body 208. The top rod 211 is supported by a lifting plate 212, and the lifting plate 212 is used to connect the lifting structure.

[0045] The top mold body 208 is placed on the top of the limit frame 204, and there is an assembly hole 209 in the center of the top mold for installing the diverter cone. In addition, a top rod 211 is arranged above the top mold, which is supported by a lifting plate 212, and the lifting plate 212 can be connected to an external lifting structure to control the up and down movement of the top mold to realize the opening and closing of the mold.

[0046] The wheel hub mold further includes a cooling pipeline 210 , and the cooling pipeline 210 is disposed in the bottom mold and the top mold.

[0047] In order to speed up the cooling of the wheel hub, shorten the molding cycle and improve production efficiency, a complete set of cooling pipes 210 system is provided in the mold. The cooling pipes 210 are cleverly arranged inside the bottom mold and the top mold, which can effectively take away the heat during the casting process, so that the wheel hub can be quickly solidified and formed. This not only helps to improve the microstructure of the wheel hub and improve its mechanical properties, but also reduces the deformation caused by thermal stress and ensures the dimensional accuracy of the product.

[0048] In summary, the design of this wheel hub mold fully considers all aspects of the casting process, from the introduction, distribution, purification of materials to the final cooling and solidification, each step has been optimized. Such a design not only improves production efficiency and reduces production costs, but also ensures that each wheel hub product can meet high standards of quality requirements.
