[0003] In the field of aluminum profile extrusion molding technology, traditional mold design often suffers from problems such as uneven flow distribution, poor material flow, and insufficient molding precision. These problems not only affect the quality of finished aluminum profiles, but may also lead to a shortened mold life and increased production costs. In particular, the extrusion molding effect is poor for multi-chamber aluminum profiles with complex structures. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-chamber aluminum profile extrusion die, which provides uniform flow distribution, good extrusion molding effect, and long service life.

[0005] A multi-chamber aluminum profile extrusion die according to an embodiment of the present invention includes a front die, a flow guide, and a rear die connected in sequence. The front die has a central flow distribution area and a side flow distribution area, with the side flow distribution area surrounding the central flow distribution area.

A forming core is provided on the side of the flow guide near the rear die, and the forming core has a central forming cavity. The opposite ends of the central flow guide channels are respectively connected to the central flow distribution cavity and the central forming cavity. The rear die has a side forming cavity, and the forming core passes through the side forming cavity. The opposite ends of the side flow guide channels are respectively connected to the side flow distribution cavity and the side forming cavity. The central forming cavity and the side forming cavity are connected.

[0006] According to some embodiments of the present invention, in a multi-chamber aluminum profile extrusion die, the cross-sectional area of ​​the central flow channel is smaller than the cross-sectional area of ​​the central flow chamber, and the cross-sectional area of ​​the edge flow channel is smaller than the cross-sectional area of ​​the edge flow chamber.

[0007] According to some embodiments of the present invention, a multi-chamber aluminum profile extrusion die has a cross-shaped cross-section in the central forming cavity, and all four ends of the central forming cavity are connected to the frame forming cavity.

[0008] According to some embodiments of the present invention, a multi-chamber aluminum profile extrusion die is provided with four central flow distribution cavities and four central flow guide channels. The ends of the four central flow guide channels away from the central flow distribution cavities are respectively connected to the four segments of the central forming cavity.

Furthermore, the central flow distribution cavity corresponds to the central guide channel and is used to transport the molten metal to the central forming cavity, while the edge flow distribution cavity and the edge guide channel match and are used to transport the molten metal to the edge forming cavity. This allows for concentrated extrusion filling of different areas, thereby improving the uniformity and consistency of the finished multi-chamber aluminum profile and resulting in a good forming effect.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0025] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0026] Traditional mold designs often suffer from uneven flow distribution, poor material flow, and insufficient forming precision. These problems not only affect the quality of the finished aluminum profiles but can also shorten mold life and increase production costs, especially for complex multi-chamber aluminum profiles, resulting in poor extrusion molding effects. Traditional molds typically lack precise flow control mechanisms, making it difficult to meet the production demands of high-precision, highly complex aluminum profiles. In actual operation, the flow of molten metal within the mold often encounters uneven resistance, leading to uneven material distribution. Particularly at the edges and junctions of the mold, insufficient filling or over-extrusion can easily occur, making it difficult to achieve ideal forming results.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 6 This utility model discloses a multi-chamber aluminum profile extrusion die, comprising a front die 1, a flow guide 2, and a rear die 3 connected in sequence. The flow guide 2 and the rear die 3 are respectively connected to opposite sides of the front die 1. The front die 1 has a central flow distribution area and a border flow distribution area. The border flow distribution area surrounds the central flow distribution area. The central flow distribution area has several evenly distributed central flow distribution cavities 11, with a gap between each adjacent pair of central flow distribution cavities 11 to ensure that the space of each central flow distribution cavity 11 within the flow guide 2 is independent. The border flow distribution area has several border flow distribution cavities 12, with a gap between each adjacent pair of border flow distribution cavities 12 to ensure that the space of each border flow distribution cavity 12 within the flow guide 2 is independent. Similarly, a gap is formed between each central flow distribution cavity 11 and the adjacent border flow distribution cavity 12, ensuring that the spaces of the central flow distribution cavity 11 and the border flow distribution cavity 12 within the flow guide 2 are independent. The flow guide 2 is equipped with several central flow guide channels 21, each with a position and number that match the central flow guide cavities 11. The flow guide 2 is also equipped with several side flow guide channels 22, each with a position and number that match the side flow guide cavities 12. The flow guide 2 is equipped with a forming core 23 on the side near the rear mold 3. The forming core 23 is equipped with a central forming cavity 24. The two ends of the central flow guide channels 21 are respectively connected to the central flow guide cavities 11 and the central forming cavity 24. The rear mold 3 is equipped with a side forming cavity 31. The forming core 23 passes through the side forming cavity 31. A space for forming aluminum profiles is formed between the side of the forming core 23 and the cavity wall of the side forming cavity 31. The two ends of the side flow guide channels 22 are respectively connected to the side flow guide cavities 12 and the side forming cavity 31. The central forming cavity 24 is connected to the side forming cavity 31, specifically, the end of the central forming cavity 24 is connected to the side forming cavity 31.

[0029] By setting a central flow distribution area and a border flow distribution area in the front mold 1, and configuring independent central flow distribution cavities 11 and border flow distribution cavities 12 respectively, uniform flow distribution of the molten metal is effectively achieved. Furthermore, the central flow distribution cavity 11 corresponds to the central guide channel 21 and is used to deliver molten metal to the central forming cavity 24, while the border flow distribution cavity 12 matches the border guide channel 22 and is used to deliver molten metal to the border forming cavity 31. Targeted extrusion filling is achieved for different areas, thereby improving the uniformity and consistency of the finished multi-chamber aluminum profile. The central guide channel 21 and border guide channel 22 in the flow guide 2 respectively... With precise matching between the central flow channel 11 and the edge flow channel 12, the molten metal can accurately and efficiently enter the forming die core 23. This extrusion die design optimizes the metal flow path, reduces stress concentration and wear points inside the die, thereby extending the die's service life. At the same time, a corresponding module is set for each cavity, which facilitates die maintenance and reduces production costs. Due to the precise control and efficient forming of the molten metal, this extrusion die can significantly reduce scrap rate and production cycle during the production process, improve production efficiency, and bring higher economic benefits.

[0030] It is understood that the cross-sectional area of ​​the central flow channel 21 is smaller than that of the central flow divider 11, and the cross-sectional area of ​​the border flow channel 22 is smaller than that of the border flow divider 12. The cross-sections corresponding to the aforementioned cross-sectional areas are all perpendicular to the flow direction of the molten metal. The molten metal is input from the front mold 1, and the central flow divider 11 and the border flow divider 12 form a good flow divider effect. The molten metal in the central flow divider 11 enters the central flow channel 21 after being gathered, and the molten metal in the border flow divider 12 enters the border flow channel 22 after being gathered, which can effectively improve the uniformity of the filling effect.

[0031] It is understandable that the cross-section of the central forming cavity 24 is cross-shaped, and all four ends of the central forming cavity 24 are connected to the frame forming cavity 31. Through the cross-shaped central forming cavity 24, an aluminum profile with a stable internal support structure can be formed, which can effectively improve the stability of the aluminum profile structure.

[0032] Furthermore, there are four central distribution cavities 11 and four central guide channels 21. One end of each of the four central guide channels 21 is connected to one of the four central distribution cavities 11, and the other end of each of the four central guide channels 21 away from the central distribution cavities 11 is connected to one of the four segments of the cross-shaped structure of the central forming cavity 24. The molten metal output from the four central distribution cavities 11 passes through the four central guide channels 21 and arrives at the corresponding segment of the central forming cavity 24. By transporting the molten metal of each segment through small-volume and independent cavities, the uniformity of flow filling can be effectively ensured, which can further improve the stability of extrusion molding.

[0033] It is understandable that the rear mold 3 is also provided with an output cavity 32. The output cavity 32 is connected to the side of the frame forming cavity 31 away from the guide 2. Since the cross-sectional area of ​​the output cavity 32 is larger than the cross-sectional area of ​​the frame forming cavity 31, the stability of the output action after the multi-chamber profile is extruded can be effectively ensured.

[0034] Understandably, the rear mold 3 is made of ceramic. Ceramic has excellent corrosion resistance, wear resistance and high thermal conductivity. Compared with traditional metal materials, the ceramic rear mold 3 can accelerate the cooling rate of the internal molten metal, effectively improve the molding speed, and the rapidly solidified aluminum profile has a more stable structure, which can reduce the impact on the molding effect caused by the loss of support and restraint after output. The extrusion molding effect is stable and reliable.

[0035] Furthermore, the flow guide 2 and its connected forming core 23 are also ceramic structures. The ceramic structure of the forming core 23 can accelerate the forming of the internal structure of the aluminum profile. The flow guide 2 can provide a pre-cooling effect for the final curing of the aluminum profile, which can accelerate the overall extrusion molding process.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
