Description

Technical Field

[0001] This utility model is a flow divider cone structure, belonging to the field of flow divider cones. Background Technology

[0002] Die casting, as an efficient metal forming process, is widely used in automobile manufacturing, aerospace and 3C electronics. In the die casting process, the flow divider cone is the core component that guides the flow of molten metal and adjusts the filling path. Its structural design directly affects the uniformity of molten metal flow, the thermal balance of the mold, and the quality of the casting.

[0003] Currently, traditional die-casting flow dividers face multiple technical bottlenecks in structural design and manufacturing processes. Structurally, existing flow dividers and mounting plates are mostly integrally molded. While this design simplifies assembly, it presents limitations in mold repair and component replacement. Local damage often necessitates complete replacement, increasing maintenance costs. Regarding the cooling system, the internal cooling channels of integral flow dividers often employ a straight-cylinder structure. Although this structure is easy to manufacture, the coolant flow path is short and the turbulence is low, making it difficult to meet the heat dissipation requirements of high-melting-point alloy die casting. This easily leads to localized overheating of the flow divider, resulting in problems such as molten metal sticking to the mold and mold thermal fatigue cracks. While some flow dividers with complex spiral groove channels can effectively improve cooling efficiency, they are limited by traditional machining processes and require 3D printing technology. This significantly increases manufacturing costs and extends the production cycle, making it difficult to meet the large-scale, low-cost production needs of the die-casting industry. Therefore, designing a flow divider structure is essential. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flow divider cone structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a flow divider cone structure, including an upper mold, which is hollow, and the bottom center of the upper mold protrudes upward to form a flange, and an installation groove is provided at the center of the flange;

[0006] The mounting plate is fixed to the mounting groove of the upper mold by fixing bolts;

[0007] The main body of the diversion cone is fixed to the center of the bottom of the mounting plate by fastening bolts, and a conical cavity is opened at the top of its interior.

[0008] The center seat is located in the center of the conical cavity and is an integral part of the main body of the diversion cone;

[0009] The water-cooling channel is located in the conical cavity on the outer periphery of the central seat;

[0010] There are two water guiding channels, symmetrically arranged on both sides inside the mounting plate, running through the mounting plate. The top of the two water guiding channels is respectively provided with a water inlet and a water outlet.

[0011] Furthermore, the bottom of the mounting plate is inserted into and penetrates the mounting groove, and the shape of the lower half of the mounting plate matches the internal shape of the mounting groove, while the top shape of the mounting plate is consistent with the flange.

[0012] Furthermore, four through-holes are equally spaced at the edge of the top of the mounting plate, and mounting screw holes are provided at the top of the flange corresponding to the positions of the positioning holes. The fixing bolts pass through the positioning holes and are threadedly connected to the mounting screw holes.

[0013] Furthermore, a first threaded hole is provided at the center of the mounting plate, and a countersunk hole is provided in the mounting plate at the top of the first threaded hole. A second threaded hole corresponding to the first threaded hole is provided at the center of the center seat, and the fastening bolt is threadedly connected to both the first threaded hole and the second threaded hole. The shape of the countersunk hole matches the end shape of the fastening bolt.

[0014] Furthermore, a convex sealing outer edge is provided at the top edge of the diversion cone body, and a sealing ring groove with a shape matching the sealing outer edge is provided at the bottom of the mounting plate. A sealing rubber ring is bonded to the inner wall of the sealing ring groove, and the bottom diameter of the mounting plate is larger than the top diameter of the diversion cone body.

[0015] Furthermore, four protrusions are provided at equal angles at the top edge of the center seat, and a groove matching the shape of the protrusions is provided at the bottom of the mounting plate at the position corresponding to the protrusions.

[0016] Furthermore, the central axis of the diversion cone body coincides with that of the mounting plate, and the bottom of the diversion cone body is designed in a conical shape, with the bottom wall of the conical cavity and the outer wall of the diversion cone body maintaining an equal distance.

[0017] Furthermore, the water-cooling channel is composed of several concentric and equally spaced partition rings. The top of the partition ring is flush with the center seat, and the bottom of the partition ring is connected to the bottom wall of the conical cavity and integrally formed with the main body of the diversion cone. Each partition ring has a through groove, which symmetrically divides the partition ring into two semi-ring structures. The through grooves on adjacent partition rings are staggered by 180° in the circumferential direction to form a spiral water flow channel.

[0018] The beneficial effects of this utility model are:

[0019] Unlike traditional one-piece molded structures, this application designs the diversion cone body and the mounting plate as a separate structure. Through multiple positioning connections such as fastening bolts, locking protrusions and slots, when the diversion cone body is partially damaged, it can be disassembled and replaced separately without the need for overall scrapping, which greatly reduces maintenance costs. At the same time, the separate design facilitates daily maintenance and cleaning, improving equipment maintenance efficiency.

[0020] Instead of a straight-cylinder cooling channel, a spiral water-cooling channel composed of concentric partition rings is adopted. The coolant flows along the spiral path formed by the intersecting grooves, which extends the heat exchange path and enhances the turbulence effect. The conical cavity and the outer wall of the main body of the flow divider are designed with the same wall thickness to ensure that the coolant cools all parts of the outer wall of the flow divider. This avoids localized inadequate cooling due to uneven wall thickness and effectively reduces local overheating of the flow divider. The top surface of the spiral water-cooling channel is open, which can be achieved by conventional machining without relying on 3D printing technology, reducing manufacturing costs and improving production efficiency.

[0021] The connection between the mounting plate and the main body of the diverter cone adopts a double sealing structure of "sealing outer edge and sealing ring groove fit + sealing rubber ring". The sealing rubber ring tightly fills the gap under axial pressure, forming the first anti-leakage barrier. The radial nesting structure of the sealing outer edge and sealing ring groove further blocks the coolant leakage path. At the same time, combined with multiple positioning and fastening measures such as fastening bolts and locking protrusions and grooves, the structure can still maintain stability during high-frequency and high-pressure die casting cycle, avoid loosening of the diverter cone body, effectively prevent coolant leakage, and improve the reliability and safety of equipment operation.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Please see Figures 1 to 4 The present invention provides a technical solution: a flow divider cone structure, including an upper mold 1, the upper mold 1 being hollow, and a flange 101 protruding upward from the center of the bottom of the upper mold 1, with an installation groove 102 provided at the center of the flange 101;

[0030] Mounting plate 2 is fixed to mounting groove 102 of upper mold 1 by fixing bolts 7;

[0031] The main body 5 of the diversion cone is fixed to the center of the bottom of the mounting plate 2 by fastening bolts 6, and a cone-shaped cavity 502 is opened at the top of its interior.

[0032] The center seat 501 is located at the center of the conical cavity 502, and the center seat 501 and the main body of the diversion cone 5 are designed as a single unit.

[0033] The water-cooling channel 8 is located in the conical cavity 502 on the outer periphery of the center seat 501;

[0034] There are two water guiding channels 202, which are symmetrically arranged on both sides inside the mounting plate 2. The water guiding channels 202 penetrate through the mounting plate 2. The top of the two water guiding channels 202 is respectively provided with a water inlet 3 and a water outlet 4. The diversion cone body 5 and the mounting plate 2 adopt a split structure and are connected by fastening bolts 6. When the diversion cone body 5 is worn or damaged, it can be disassembled and replaced independently without the need for overall scrapping, which reduces maintenance costs compared with the traditional one-piece molding structure.

[0035] Please see Figure 2The bottom of the mounting plate 2 is inserted into and passes through the mounting groove 102, and the shape of the lower half of the mounting plate 2 matches the internal shape of the mounting groove 102. The top shape of the mounting plate 2 is consistent with the flange 101. The bottom of the mounting plate 2 can be directly inserted into and passes through the mounting groove 102. Its lower half matches the internal shape of the mounting groove 102, and its top matches the shape of the flange 101. This design allows the mounting plate 2 to quickly find the correct position during assembly without a complicated debugging process, which greatly shortens the assembly time and improves production efficiency.

[0036] Please see Figure 2 and Figure 3 Four through-holes 201 are equally spaced at the top edge of the mounting plate 2, and mounting screw holes 103 are provided at the top of the flange 101 corresponding to the positions of the positioning holes 201. The fixing bolts 7 pass through the positioning holes 201 and are threadedly connected to the mounting screw holes 103. Through the tightening action of the four fixing bolts 7, an axial preload is formed between the mounting plate 2 and the upper mold 1. Combined with the nesting fit between the bottom of the mounting plate 2 and the mounting groove 102, the shear strength of the connection part is improved. During the die casting process, it can effectively resist the instantaneous high pressure impact generated when the molten metal is filled, prevent the mounting plate 2 from loosening or falling off, and ensure the reliability of the mold structure in high-frequency cycle operation.

[0037] Please see Figure 3 A first threaded hole 204 is provided at the center of the mounting plate 2, and a countersunk hole 205 is provided in the mounting plate 2 at the top of the first threaded hole 204. A second threaded hole 505 corresponding to the first threaded hole 204 is provided at the center of the center seat 501. The fastening bolt 6 is threadedly connected to both the first threaded hole 204 and the second threaded hole 505. The shape of the countersunk hole 205 matches the end shape of the fastening bolt 6. The first threaded hole 204 of the mounting plate 2 and the second threaded hole 505 of the center seat 501 are precisely corresponding. The fastening bolt 6 is threadedly connected to both threaded holes, which can provide strong axial tensile force, so that the mounting plate 2 and the diverter cone body 5 are tightly fixed. This ensures that the two will not be relatively displaced when subjected to high pressure impact of molten metal during the die casting process. The shape of the countersunk hole 205 matches the end shape of the fastening bolt 6, ensuring that the surface of the fastening bolt 6 is flat after it is fixed, and preventing collision damage caused by the protrusion of the end of the fastening bolt 6.

[0038] Please see Figure 3 and Figure 4A convex sealing outer edge 504 is provided at the top edge of the flow divider cone body 5, and a sealing ring groove 206 with a shape matching the sealing outer edge 504 is provided at the bottom of the mounting plate 2. A sealing rubber ring is bonded to the inner wall of the sealing ring groove 206, and the bottom diameter of the mounting plate 2 is larger than the top diameter of the flow divider cone body 5. The nested structure of the sealing outer edge 504 and the sealing ring groove 206 forms the first physical sealing barrier, effectively preventing coolant leakage. The sealing rubber ring bonded to the inner wall of the sealing ring groove 206 is deformed under pressure when the mounting plate 2 and the flow divider cone body 5 are tightened, filling the tiny gaps and forming a second elastic sealing layer. The dual sealing mechanism can reduce the coolant leakage rate.

[0039] Please see Figure 2 and Figure 3 Four protrusions 506 are evenly distributed at the top edge of the center seat 501, and a groove 203 matching the shape of the protrusions 506 is opened at the bottom of the mounting plate 2 at the position corresponding to the protrusions 506. The four protrusions 506 evenly distributed at the top edge of the center seat 501 and the groove 203 at the bottom of the mounting plate 2 form a precise circumferential positioning reference. This design can prevent the flow divider cone body 5 from rotating relative to the mounting plate 2, ensure the precise docking of the water cooling channel 8 and the water guiding channel 202, and avoid obstruction of coolant flow.

[0040] Please see Figure 4 The central axis of the flow divider cone body 5 coincides with that of the mounting plate 2, and the bottom of the flow divider cone body 5 is designed in a conical shape. The bottom wall of the conical cavity 502 and the outer wall of the flow divider cone body 5 are kept at equal distances. The central axis of the flow divider cone body 5 and the mounting plate 2 are strictly coincident. With the conical design at the bottom and the equal wall thickness structure, the flow resistance deviation in all directions of the molten metal is kept small during the flow divider process, so as to achieve uniform flow divider. The equal distance design between the bottom wall of the conical cavity 502 and the outer wall of the flow divider cone body 5 keeps the contact area and heat exchange conditions between the coolant and the outer wall of the flow divider cone body 5 consistent, so as to avoid local overheating problems caused by differences in wall thickness.

[0041] Please see Figure 3 and Figure 4The water-cooling channel 8 is composed of several concentric and equally spaced partition rings 503. The top of the partition ring 503 is flush with the center seat 501, and the bottom of the partition ring 503 is connected to the bottom wall of the conical cavity 502 and integrally formed with the main body 5 of the flow divider cone. Each partition ring 503 has a through groove, which symmetrically divides the partition ring 503 into two semi-ring structures. The through grooves on adjacent partition rings 503 are staggered by 180° in the circumferential direction to form a spiral water flow channel. The spiral water flow channel constructed in section 3 causes the coolant to flow in a spiral path within the main body 5 of the diversion cone, significantly increasing the degree of turbulence. At the same time, the through grooves on the adjacent partition rings 503 are arranged in a 180° circumferential offset, forcing the coolant to continuously change its flow direction, further disrupting the boundary layer and enhancing the convective heat transfer effect. The partition rings 503 and the main body 5 of the diversion cone are integrally formed, and the top surface of the water cooling channel 8 is open, which can be achieved through conventional machining such as milling and turning, reducing manufacturing costs and shortening the production cycle.

[0042] Detailed implementation method: During assembly, the bottom of the mounting plate 2 is inserted into the mounting groove 102 of the upper mold 1, and is fastened by the fixing bolt 7 through the positioning hole 201 and the mounting screw hole 103; the snap protrusion 506 of the diverter cone body 5 is embedded into the snap groove 203 of the mounting plate 2, and is fixed by the fastening bolt 6 through the first threaded hole 204 and the second threaded hole 505. The sealing outer edge 504 is nested with the sealing ring groove 206 of the mounting plate 2, and a double seal is achieved with the sealing rubber ring to prevent coolant leakage. The conical design at the bottom of the diverter cone body 5 and the conical cavity 502 with equal wall thickness make the flow resistance of the molten metal uniform in all directions and evenly fill the cavity. The coolant flows from the inlet 3 into the water cooling channel 8 through the water guide channel 202, flows in the spiral path formed by the through groove of the partition ring 503, enhances turbulent heat transfer, and finally is discharged from the drain outlet 4 to cool the diverter cone body 5.
