Description

Technical Field

[0001] This utility model relates to the field of aluminum profile extrusion production technology, specifically to an extrusion die for thermally broken aluminum alloy profiles. Background Technology

[0002] Aluminum alloy profile extrusion dies are key tools used to extrude heated aluminum alloy billets under high pressure. Their core function is to control the cross-sectional shape and dimensional accuracy of aluminum profiles. The die is a thick circular steel disc made of high-strength alloy steel, containing one or more die holes. High pressure forces the aluminum billet to plastically deform, forming a profile with a specific cross-sectional shape.

[0003] Because the extrusion process of aluminum alloy profiles needs to be carried out at high temperatures, the molds are subjected to a lot of high-temperature impacts during the operation. Furthermore, the existing upper and lower molds are usually connected by screws. High temperatures can melt the threads of the screws and screw holes, making it difficult to disassemble the upper and lower molds and affecting cleaning and replacement. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the above-mentioned problems and the existing problems in the extrusion dies of thermally broken aluminum alloy profiles, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A thermally broken aluminum alloy profile extrusion die includes an upper die and a lower die. The upper die and the lower die are each provided with a connecting mechanism on their respective sides. The connecting mechanism includes a slide groove on one side of the upper die, and a slide plate is slidably installed inside the slide groove. An inclined locking block and a control rod are respectively fixedly connected to one side and the top of the slide plate. An elastic element is provided at the bottom of the slide plate. The connecting mechanism also includes a connecting hole on one side of the lower die, and a limiting locking block is provided inside the connecting hole.

[0007] As a preferred embodiment of the thermal break aluminum alloy profile extrusion die of this utility model, when the upper die is connected to the lower die, the inclined block is disposed inside the connection hole and cooperates with and restricts the limiting block.

[0008] In a preferred embodiment of the thermal break aluminum alloy profile extrusion die of this utility model, the inclined block slides through the groove and penetrates the upper die, and the control rod penetrates the upper die.

[0009] In a preferred embodiment of the thermal break aluminum alloy profile extrusion die of this utility model, the elastic element is disposed inside the slide groove and located between the bottom end of the slide plate and the inner wall of the bottom end of the slide groove.

[0010] As a preferred embodiment of the thermal break aluminum alloy profile extrusion die of this utility model, the upper die is provided with multiple flow dividers, and flow dividers are provided between the multiple flow dividers, and the multiple flow dividers and flow dividers are arranged in a ring array.

[0011] As a preferred embodiment of the thermally broken aluminum alloy profile extrusion die of this utility model, a welding chamber is provided at the end of the lower die that is close to the upper die, and a die hole is provided on the inner side of the welding chamber.

[0012] As a preferred embodiment of the thermal break aluminum alloy profile extrusion die of this utility model, the inner wall of the die hole is provided with a working belt, and a die core is provided at one end of the upper die and the lower die, and the die core is adapted to the working belt.

[0013] As a preferred embodiment of the thermal break aluminum alloy profile extrusion die of this utility model, the inner wall of the working belt is provided with multiple microgrooves, and the multiple microgrooves are evenly distributed.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The connection mechanism facilitates the connection and separation of the upper and lower dies, avoiding the problem of traditional screw connections melting easily at high temperatures and being difficult to separate. This also makes it easier to clean and replace the dies. During the extrusion of aluminum alloy profiles, the lower die directly contacts the high-temperature metal flow, and due to the heat accumulation effect, the high-temperature impact on the lower die is usually more significant than that on the upper die. Therefore, most of the components of the connection mechanism are installed inside the upper die to prevent the connection mechanism from melting easily and affecting the connection and separation between the upper and lower dies.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example 1

[0020] Please see Figures 1-5 This utility model provides a technical solution: A thermally broken aluminum alloy profile extrusion die includes an upper die 1 and a lower die 2. A connecting mechanism is provided on one side of both the upper die 1 and the lower die 2. The connecting mechanism includes a slide groove 12 on one side of the upper die 1, with a sliding plate 13 slidably installed inside the slide groove 12. An inclined locking block 14 and a control rod 15 are fixedly connected to one side and top of the sliding plate 13, respectively. An elastic element 16 is provided at the bottom of the sliding plate 13. The connecting mechanism also includes a connecting hole 10 on one side of the lower die 2, with a limiting locking block 11 inside the connecting hole 10. This connecting mechanism facilitates the connection and separation of the upper die 1 and the lower die 2, avoiding the problem of traditional screw connections melting easily at high temperatures and being difficult to separate. It also facilitates the cleaning and replacement of the die. Since the lower die 2 directly contacts the high-temperature metal flow during the aluminum alloy profile extrusion process, and due to the heat accumulation effect, the high-temperature impact on the lower die 2 is usually more significant than that on the upper die 1. Therefore, most components of the connecting mechanism are installed inside the upper die 1 to prevent the connecting mechanism from melting easily and affecting the connection and separation between the upper die 1 and the lower die 2.

[0021] When the upper mold 1 is connected to the lower mold 2, the inclined locking block 14 is set inside the connecting hole 10 and cooperates with and restricts the limiting block 11. The limiting block 11 and the inclined locking block 14 are a mechanical locking connection method. Compared with the traditional screw connection, it is more durable in high temperature environments and less likely to fail due to high temperature.

[0022] The inclined block 14 slides through the slide groove 12 and penetrates the upper mold 1. The control rod 15 penetrates the upper mold 1 and is used to push the slide plate 13 to move, thereby controlling the action of the inclined block 14. This provides operators with convenient control components, making it easy for operators to control the connection status of the mold, thereby facilitating the disassembly of the mold and making cleaning and replacement work more convenient and faster.

[0023] The elastic element 16 is located inside the slide groove 12 and between the bottom end of the slide plate 13 and the inner wall of the bottom end of the slide groove 12. Since the lower die 2 will directly contact the high temperature metal flow during the extrusion process of aluminum alloy profile, and due to the heat accumulation effect, the high temperature impact borne by the lower die 2 is usually more significant than that of the upper die 1. Therefore, most of the components of the connecting mechanism are installed inside the upper die 1 to avoid the connecting mechanism from melting and affecting the connection and separation between the upper die 1 and the lower die 2.

[0024] During use, the mold is installed in the designated position, and then the heated aluminum alloy billet is pressurized by the extrusion equipment. The aluminum alloy billet enters the welding chamber 6 through the diversion hole 4, and then is heated inside the welding chamber 6. It is then extruded and formed through the die hole 7. The die core 5 cooperates with the working belt 8 to determine the internal shape and dimensional accuracy of the formed profile. The microgroove 9 can reduce the friction coefficient between the aluminum alloy billet and the working belt 8, thereby improving the service life of the mold. When it is necessary to separate the upper mold 1 and the lower mold 2, the control rod 15 pushes the slide plate 13 to move in the slide groove 12. The slide plate 13 will drive the inclined block 14 to move. The inclined block 14 will move inward and cancel its engagement with the limiting block 11. Then the upper mold 1 and the lower mold 2 can be separated, which is convenient for cleaning and replacement of the mold. When connecting, the inclined block 14 of the upper mold 1 and the connecting hole 10 of the lower mold 2 are aligned. After entering the connecting hole 10, the inclined block 14 will engage with the limiting block 11 under the action of the elastic element 16, thereby realizing the connection between the upper mold 1 and the lower mold 2. Example 2

[0025] Please see Figures 1-5 This utility model provides a technical solution: The upper mold 1 has multiple flow dividers 3 inside, and flow dividers 4 are arranged between the multiple flow dividers 3. The multiple flow dividers 3 and flow dividers 4 are arranged in a ring array. The multiple flow dividers 3 and flow dividers 4 are arranged in a ring array, which can more evenly divide the aluminum alloy blank, so that the flow rate and pressure of the blank are consistent, ensuring the uniformity of subsequent welding and forming, and improving the quality of the profile.

[0026] A welding chamber 6 is provided at one end of the lower mold 2 that is close to the upper mold 1. A mold hole 7 is provided on the inner side of the welding chamber 6. The welding chamber 6 allows the multiple strands of aluminum alloy blanks after diversion to be re-welded here, ensuring the integrity and strength of the profile and avoiding defects such as delamination.

[0027] The inner wall of the die hole 7 is provided with a working belt 8. The upper die 1 and the lower die 2 are provided with a die core 5. The die core 5 is adapted to the working belt 8. The die hole 7 can accurately control the external cross-sectional shape of the profile to ensure that the profile meets the size and appearance requirements.

[0028] The inner wall of the working belt 8 is provided with multiple micro-grooves 9, which are evenly distributed. The micro-grooves 9 can reduce the friction between the working belt 8 and the aluminum alloy blank and make the friction distribution of the aluminum alloy blank on the working belt 8 more uniform, thereby improving the service life of the mold and making the extrusion process more stable.

[0029] Unlike Example 1, by cooperating with each component in the upper mold 1 and the lower mold 2, the integrity, strength and appearance quality of the aluminum alloy profile can be guaranteed after forming. At the same time, the microgrooves 9 can reduce the friction between the working belt 8 and the aluminum alloy blank and make the friction distribution of the aluminum alloy blank on the working belt 8 more uniform, thereby improving the service life of the mold and making the extrusion process more stable.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
