Technical Field
[0001] This utility model relates to the field of aluminum profile extrusion die technology, specifically a diversion guide plate for quick assembly and disassembly of aluminum profile extrusion die. Background Technology
[0002] Aluminum profiles possess a range of excellent properties, such as high strength, good weather resistance, and low density, making them widely used in construction and industry. Currently, the production process of aluminum profiles requires the use of aluminum profile extrusion dies to shape them. In existing technology, aluminum profile extrusion dies include a front die and a rear die. The front die contains a flow guide plate, flow holes, and a die core, while the rear die includes a shell and a welding chamber. The aluminum rod deforms and flows through the front die, and is then reshaped in the rear die to obtain an aluminum profile with the corresponding structure.
[0003] However, the front dies currently in use are generally of a one-piece structure. When processing different aluminum rods, the requirements for the flow divider plate in the front die are different, so the flow divider plate needs to be replaced. Currently, replacing the flow divider plate requires replacing the entire front die, which is time-consuming, labor-intensive, and also increases the manufacturing cost of the front die. To address this, we propose a quick-assembly and disassembly flow divider plate for aluminum profile extrusion dies. Utility Model Content

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0025] like Figures 1-7 As shown, this utility model provides a technical solution: a quick-release diversion guide plate for an aluminum profile extrusion die, comprising: a core 3; a die shell 2 is sleeved on the outside of the core 3, the core 3 and the die shell 2 are detachable and replaceable, a surrounding plate 1 is fixedly installed on the outside of the die shell 2, a positioning plate 4 is provided inside one end of the die shell 2, the positioning plate 4 is sleeved on the outside of one end of the core 3, an elastic support member 5 is provided on the front side of the positioning plate 4, a limiting component 6 is provided on the front side of the positioning plate 4 through the elastic support member 5, the limiting component 6 is used to limit the core 3 inside the die shell 2, and an elastic clamp 7 is sleeved on the front end of the core 3, the elastic clamp 7 is used to position the limiting component 6.
[0026] In this embodiment, the core 3 is included. The extrusion die includes two main parts: a die shell 2 and a core 3. The core 3 can be replaced inside the die shell 2, thereby solving the drawback of replacing the whole die when changing the die and reducing the production cost. Several liner blocks 31 are fixedly installed on the outside of the core 3. The liner blocks 31 are inserted into the slot 21. An outer ring 32 is fixedly installed at the front end of the core 3. A flow divider 33 is provided inside the core 3. A die core 34 is provided at the center of the flow divider 33. An aluminum rod is inserted into the outside of the outer ring 32 and abuts against the flow divider 33. When the aluminum rod is extruded by a hydraulic press, one end of the aluminum rod is located inside the outer ring 32, and the other end of the aluminum rod is in contact with the end of the output rod of the hydraulic press.
[0027] In this embodiment, the core 3 is sleeved with a mold shell 2. The core 3 and the mold shell 2 are detachable and replaceable. The inner sidewall of the mold shell 2 is provided with a number of slots 21 and positioning grooves 22. The depth of the slots 21 is greater than the depth of the positioning grooves 22. The slots 21 have an open structure on one side, and the positioning grooves 22 have a closed structure. When installing the core 3, the pad 31 of the core 3 is inserted into the inside of the slots 21, thereby realizing the stable installation of the core 3 inside the mold shell 2 and preventing the core 3 from rotating inside the mold shell 2. At the same time, when the aluminum rod extrudes the core 3, it also ensures the reliable support strength of the core 3 inside the mold shell 2.
[0028] In this embodiment, a surrounding plate 1 is fixedly installed on the outside of the mold shell 2. The corner of the surrounding plate 1 is provided with an installation hole, and the surrounding plate 1 is fixedly connected to the mold shell 2. The surrounding plate 1 is used to fix the mold shell 2, which facilitates the fixed installation of the whole mold on the hydraulic press.
[0029] In this embodiment, a positioning plate 4 is provided inside one end of the mold shell 2. The positioning plate 4 is sleeved on the outside of one end of the core 3. Several through grooves 41 are provided on the inner side wall of the positioning plate 4. When the liner 31 is installed, it can pass through the inside of the through grooves 41, so that the core 3 can be disassembled in the mold shell 2. The core 3 can pass through the inside of the limiting component 6 and the positioning plate 4, realizing the quick assembly and disassembly of the core 3. Several positioning blocks 42 are fixedly installed on the outer back wall of the positioning plate 4. The positioning blocks 42 can be used to insert the positioning plate 4 into the inside of the positioning groove 22 when it is installed, ensuring the stability of the positioning plate 4 inside the mold shell 2 and preventing the positioning plate 4 from rotating. Several guide rails 43 are provided on the outer front wall of the positioning plate 4. The limiting strip 63 is just inserted between the guide rails 43 distributed on the inner and outer sides, realizing the guiding function of the rotating ring 61.
[0030] In this embodiment, an elastic support 5 is provided on the front of the positioning plate 4. The elastic support 5 includes a fixing block 51 fixed to the outer wall of the front of the positioning plate 4, and a spring 52 is provided on one side of the fixing block 51. When the core 3 needs to be replaced, the operator can rotate the limiting component 6. At this time, the limiting component 6 rotates on the surface of the positioning plate 4, and the elastic support 5 is compressed. The limiting strip 63 moves away from the front of the liner 31, so that the core 3 can be taken out from the front of the mold shell 2, realizing the replacement of the core 3. When different structures are selected... After the core 3 is inserted into the mold shell 2, the operator releases the limiting component 6. Under the rebound action of the elastic support 5, the limiting strip 63 is once again locked on the front of the liner 31, thus positioning the core 3 inside the mold shell 2. Since the core 3 is mainly subjected to backward force inside the mold shell 2 when the aluminum rod becomes an aluminum profile, and the core 3 will not move forward and detach from the mold shell 2, the elastic support 5 and the limiting component 6 can completely achieve the limiting and fixing of the core 3 inside the mold shell 2.
[0031] In this embodiment, a limiting component 6 is provided on the front side of the positioning plate 4 through an elastic support member 5. The limiting component 6 is used to limit the core 3 inside the mold shell 2. The limiting component 6 includes a rotating ring 61 that is close to and slides on the front side of the positioning plate 4. A handle 62 is provided on one outer wall of the rotating ring 61. Several limiting strips 63 are provided on the outer wall of the rotating ring 61. The several limiting strips 63 rotate synchronously with the rotating ring 61. The handle 62 is used to facilitate the operator to drive the rotating ring 61 to rotate. The rotation of the rotating ring 61 can drive the limiting strips 63 to rotate synchronously, thereby facilitating the operator to operate the limiting component 6.
[0032] In this embodiment, an elastic clamp 7 is fitted around the front end of the core 3. The elastic clamp 7 is used to position the limiting component 6. A clamp mounting groove 35 is provided on the outer wall of the outer ring 32. The elastic clamp 7 is engaged inside the clamp mounting groove 35. One side of the elastic clamp 7 is open. After the core 3 is installed inside the mold shell 2, the operator fits the elastic clamp 7 into the clamp mounting groove 35 on the outer ring 32. The elastic clamp 7 is used to limit the rotation ring 61, thereby achieving better fixation of the limiting strip 63 on the rotation ring 61 to the bushing 31 inside the slot 21, ensuring the stability of the core 3 inside the mold shell 2.
