[0022] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution:

[0024] Example 1: An adjustable aluminum profile forming mold, comprising: mold shell 1.

[0025] Specifically, the mold outer shell 1 includes a first shell 2 and a second shell 3 that fit together. The first shell 2 and the second shell 3 are fixedly connected by bolts. The first shell 2 is fixed and has a support leg installed on its lower side. The second shell 3 can be disassembled and separated from the first shell 2. The sides of the first shell 2 and the second shell 3 that are close to each other are recessed inward to form a receiving groove 302, thereby forming a cavity between the first shell 2 and the second shell 3. A mold turntable 4 that is adapted to it is rotatably installed in the cavity of the receiving groove 302. When the second shell 3 is fixed to the first shell 2, the mold turntable 4 can only rotate between the first shell 2 and the second shell 3. When the second shell 3 is separated from the first shell 2, the mold turntable 4 can be disassembled and replaced. The surface of the mold turntable 4 has a first molding cavity 41 and a second molding cavity 42. The surface of the second shell 3 has a molding hole 3 that corresponds to the first molding cavity 41. 1. A connecting seat 52 corresponding to the forming cavity 41 is fixed on the surface of the housing 2. The connecting seat 52 is a hollow structure. The connecting seat 52 is connected to the inner cavity of the receiving groove 302 and corresponds to the forming cavity 41. Therefore, the raw material of the aluminum profile can be fed into the inner cavity of the forming cavity 41 through the connecting seat 52 and then discharged from the forming hole 31. When the forming cavity 42 is aligned with the forming hole 31 by rotating the mold turntable 4, the raw material of the aluminum profile is fed into the inner cavity of the forming cavity 42 through the connecting seat 52 and then discharged from the forming hole 31. And so on. Other forming cavities with different cross-sectional shapes can also be set on the mold turntable 4 of this device. When it is necessary to form aluminum profiles with different cross-sections, it is only necessary to rotate the mold turntable 4. However, it should be noted that in order to ensure the stability of aluminum profile forming, this device is also equipped with a related structure for positioning the rotation of the mold turntable 4. See the following text for details.

[0026] Secondly, a connecting post 43 is fixed in the middle of the mold turntable 4. A polygonal insertion hole 44 is opened through the middle of the connecting post 43. A drive shaft 6 is rotatably installed on the outside of the housing 1 2. A polygonal insertion rod 62 is fixed at one end of the drive shaft 6. The polygonal insertion rod 62 is movably inserted into the inner cavity of the polygonal insertion hole 44 and is adapted to it. When the polygonal insertion rod 62 is inserted into the inner cavity of the polygonal insertion hole 44, the rotation of the drive shaft 6 can drive the mold turntable 4 to rotate through the polygonal insertion rod 62. When the housing 2 3 is disassembled from the housing 1 2, the mold turntable 4 can move along the length direction of the polygonal insertion rod 62 to facilitate the separation of the polygonal insertion hole 44 and the polygonal insertion rod 62.

[0027] Furthermore, a worm gear 61 is fixedly sleeved on the outside of the drive shaft 6. A drive worm 21 meshes with the worm gear 61 and is rotatably mounted on the outside of the housing 2. The drive worm 21 can only rotate. When the drive worm 21 rotates, it can drive the drive shaft 6 to rotate through the meshing transmission with the worm gear 61, thereby driving the mold turntable 4 to rotate. When the drive worm 21 stops rotating, since the meshing transmission between the drive worm 21 and the worm gear 61 is unidirectional, the position of the drive shaft 6 can remain stable, thereby preventing the mold turntable 4 from rotating easily. In other words, when the drive worm 21 stops rotating, it can position the rotation of the mold turntable 4.

[0028] To improve the processing efficiency of this device, multiple forming cavities 41, 42, 31, and 52 are provided and arranged in a circular array around the axis of the mold turntable 4. The forming cavities 41 and 42 are spaced apart from each other. Therefore, this device can form multiple aluminum profiles at one time, resulting in higher processing efficiency. When the connection between the forming hole 31 and the connecting seat 52 is broken by rotating the mold turntable 4, material leakage and waste can be avoided.

[0029] To prevent leakage of aluminum profile raw material inside the mold shell 1, this application also includes a sealing gasket 32 ​​bonded and fixed to the inner wall of the receiving groove 302. The sealing gasket 32 ​​corresponds to the forming hole 31. The sealing gasket 32 ​​is used to improve the sealing between the mold turntable 4 and the forming hole 31, preventing leakage of aluminum profile raw material during extrusion. It should be noted that the inner wall of the receiving groove 302 on the shell 1 2 is also provided with a sealing gasket 32, which is used to ensure the sealing between the connecting seat 52 and the forming cavity 1 41. A support frame 33 is fixed on the surface of the shell 2 3, and the support frame 33 is located below the forming hole 31. Figure 1 As shown, the support frame 33 is provided to support the formed aluminum profile to facilitate subsequent conveying.

[0030] To improve the stability of the mold turntable 4 during installation, this application also features clearance holes 203 penetrating through the middle of both the housing 2 and housing 3, with the two ends of the connecting column 43 respectively movably passing through the two clearance holes 203. Figure 2 and Figure 3 As shown, the clearance hole 203 is mainly used to cooperate with the connecting column 43, thereby improving the stability of the mold turntable 4 after installation and preventing the mold turntable 4 from shaking and shifting position between the housing 1 2 and the housing 2 3.

[0031] In order to supply materials to this device, this application also has a feeding pipe 5 provided on the outside of the housing 2. One end of the feeding pipe 5 is fixedly connected to multiple branch pipes 51, and the multiple branch pipes 51 are respectively fixedly connected to multiple connecting seats 52. The feeding pipe 5 is mainly used to transport aluminum profile raw materials. The other end of the feeding pipe 5 is connected to a hydraulic extruder known in the prior art. The high-pressure oil pump drives the oil cylinder to extend and retract to extrude the molten aluminum profile raw materials into the mold housing 1, thereby forming an aluminum profile with the required cross-sectional shape. In addition, it should be noted that in order to avoid bending and deformation of the formed aluminum profile, the device can also add a cooling structure known in the prior art inside the housing 3, which will not be described in detail here.

[0032] To install and connect the drive shaft 6, this application also includes a fixing frame 53 fixedly connected between multiple branch pipes 51. One end of the drive shaft 6 is rotatably mounted in the middle of the fixing frame 53 via a bearing. The fixing frame 53 is mainly used for the installation and positioning of the drive shaft 6. Both ends of the drive worm 21 are rotatably connected to the surface of the housing 2 via bearing seats, which can ensure the stability of the drive worm 21 and thus prevent the drive worm 21 from disengaging from the worm wheel 61. A pulley is fixed at one end of the drive worm 21. The pulley is driven to rotate by an external motor in conjunction with a belt. According to actual needs, this device can also be provided with a protective cover on the outside of the housing 2 for dust and water protection of the drive worm 21 and the worm wheel 61, which will not be described in detail here.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
