During operation, an aluminum billet is moved into an extrusion cylinder, and the aluminum billet is extruded to pass through a discharge mold for molding. Chinese Patent Application No. CN106269954A discloses an aluminum profile extruder, which heats the aluminum profile before extrusion and then extrudes it into shape, and dissipates heat from the aluminum profile after the molding is completed.

[0004] Due to the certain thickness of the mold, after a single aluminum profile completely passes through the mold for molding, there will inevitably be aluminum profiles remaining inside the mold, which not only causes waste of aluminum profiles but also requires cleaning of the mold. Therefore, further improvement is needed. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is that after a single aluminum profile completely passes through the mold for molding, there will inevitably be aluminum profiles remaining inside the mold, which not only causes waste of aluminum profiles but also requires cleaning of the mold.

[0006] To solve the above problems, the present invention provides a composite extrusion molding device for aluminum alloy door and window profiles, including a base.

[0024] The following will describe the two embodiments of the present application in detail with reference to the accompanying drawings.

[0025] The first embodiment:

[0026] Figures 1-7 There is shown a composite extrusion forming device for aluminum alloy door and window profiles, including a base 1, one end of the base 1 is fixedly connected with a hydraulic press 2, the output end of the hydraulic press 2 is fixedly connected with a push rod 3, one end of the push rod 3 is fixedly connected with an extrusion head 4, the left side of the extrusion head 4 is provided as a transfer chamber, two through holes 401 are formed through the middle of the extrusion head 4, an inlet pipe 8 and an outlet pipe 9 are respectively fixedly connected to the interiors of the two through holes 401, the other end of the base 1 is fixedly connected with a feeding pipe 5, one end of the feeding pipe 5 is fixedly connected with a mold 6, the middle of the base 1 is fixedly connected with a linkage box 7, the top end of the linkage box 7 is fixedly connected with a driving pump 12, one ends of the inlet pipe 8 and the outlet pipe 9 are respectively fixedly connected with a second hose 11 and a first hose 10, one end of the first hose 10 is communicated with the linkage box 7, the input end and the output end of the driving pump 12 are respectively communicated with the second hose 11 and the linkage box 7, the interior of the linkage box 7 is filled with an extrusion liquid 13, the inner wall of the bottom end of the linkage box 7 is fixedly connected with an adjusting pipe 14, a filling piston 16 is slidably connected to the interior of the adjusting pipe 14, the bottom end of the linkage box 7 is fixedly connected with a driver 15, and the output end of the driver 15 is fixedly connected with the filling piston 16.

[0027] More specifically, the transfer chamber is defined as follows: during use, the aluminum alloy profile is placed inside the loading pipe 5, and then the hydraulic press 2 drives the extrusion head 4 to move inside the loading pipe 5. At this time, the space between the extrusion head 4 and the aluminum alloy profile is the transfer chamber. Then, the drive pump 12 is started to extract the extrusion liquid 13 inside the linkage box 7 and convey it to the inside of the transfer chamber. At the same time, the driver 15 is started to drive the filling piston 16 to move upward to prevent the formation of cavities inside the linkage box 7 and keep the inside of the linkage box 7 always filled with the extrusion liquid 13. When the transfer chamber is filled with the extrusion liquid 13, the filling piston 16 stops moving upward. Then, the hydraulic press 2 is started to drive the extrusion head 4 to move to the left. During the leftward movement of the extrusion head 4, the aluminum alloy profile is extruded through the mold 6 to be formed by the transfer chamber. Since the inside of the transfer chamber is filled with the extrusion liquid 13 and the extrusion liquid 13 is in a liquid state, the extrusion liquid 13 can push the aluminum alloy profile to completely pass through the mold 6 to be formed, preventing the situation where the extrusion head 4 cannot completely extrude the aluminum alloy profile due to shape limitations and avoiding the residue of the aluminum alloy profile inside the loading pipe 5. This not only reduces the waste of the aluminum alloy profile but also reduces the subsequent cleaning work of the loading pipe 5.

[0028] The second implementation method:

[0029] Figures 2-7 A composite extrusion forming device for aluminum alloy door and window profiles is shown. Different from the first implementation method, a heat sink 17 and a fan 18 are fixedly connected to the side wall of the linkage box 7. One end of the heat sink 17 is located inside the linkage box 7, and one end of the fan 18 is located on one side of the heat sink 17. A temperature sensor 19 is fixedly connected inside the linkage box 7, and the temperature sensor 19 is electrically connected to the fan 18.

[0030] Before the aluminum alloy profile is placed inside the loading pipe 5 for extrusion, it needs to be heated to enable better extrusion forming. When the extrusion liquid 13 comes into contact with the heated aluminum alloy profile, the temperature of the extrusion liquid 13 will rise rapidly, which may affect the performance of the extrusion liquid 13.

[0031] With the above settings, when extruding the aluminum alloy profile, the drive pump 12 can operate continuously to make the extrusion liquid 13 flow between the transfer chamber and the linkage box 7. When the extrusion liquid 13 flows inside the linkage box 7, the heat of the extrusion liquid 13 diffuses outward through the heat sink 17. At the same time, the fan 18 is started to dissipate heat from the heat sink 17, which can prevent the extrusion liquid 13 from affecting its own performance due to excessive temperature. The temperature sensor 19 can detect the temperature of the extrusion liquid 13 and control the power of the fan 18 according to the temperature of the extrusion liquid 13.

[0032] The composite extrusion forming device further includes an intermediate head 21, and a heat insulation head 22 is fixedly connected to the side wall of the intermediate head 21.

[0033] When extruding aluminum alloy profiles and dissipating heat from the extrusion fluid 13, heat will also be dissipated from the aluminum alloy profiles, which is not conducive to the forming of the tail of the aluminum alloy profiles. Through the above settings, the aluminum alloy profiles and the intermediate head 21 are synchronously placed inside the feeding pipe 5, and the heat insulation head 22 is in contact with the aluminum alloy profiles. At this time, the transfer chamber is located between the intermediate head 21 and the extrusion head 4, and the heat insulation head 22 can play an isolating role between the aluminum alloy profiles and the transfer chamber, preventing the extrusion fluid 13 from cooling the aluminum alloy profiles while cooling, reducing the impact on the aluminum alloy profiles, and enabling the aluminum alloy profiles to be formed better.

[0034] Ring grooves are provided on the outer walls of both the extrusion head 4 and the intermediate head 21, and a sealing ring 20 is installed inside the ring grooves.

[0035] Through the setting of the sealing ring 20, the extrusion head 4 and the intermediate head 21 can be sealed, preventing the extrusion fluid 13 from leaking out through the gap between the extrusion head 4 and the feeding pipe 5, and preventing the extrusion fluid 13 from leaking out through the gap between the aluminum alloy profiles and the extrusion head 4.

[0036] One end of the feeding pipe 5 is fixedly connected with an external head 23, and the mold 6 is fixedly connected with one end of the external head 23. The diameter of the bottom end of the mold 6 is greater than the sum of the widths of the intermediate head 21 and the heat insulation head 22.

[0037] Through the above settings, since the intermediate head 21 and the heat insulation head 22 are also flat, the aluminum alloy profiles cannot be completely emptied from the inside of the feeding pipe 5 through the intermediate head 21 and the heat insulation head 22.

[0038] Through the above settings, the aluminum profiles are discharged outward through the mold 6 via the external head 23. After the intermediate head 21 and the heat insulation head 22 move to the leftmost end of the feeding pipe 5, since the diameter of the bottom end of the mold 6 is greater than the sum of the widths of the intermediate head 21 and the heat insulation head 22, the extrusion fluid 13 can continue to extrude the aluminum alloy profiles inside the external head 23 and discharge them outward through the gap between the intermediate head 21 and the external head 23. Through the above settings, it can be ensured that the aluminum alloy profiles can be completely discharged from the inside of the feeding pipe 5 when the intermediate head 21 and the external head 23 are installed.

[0039] The volume of the transfer chamber is greater than the volume of the external head 23.

[0040] Through the above settings, when the extrusion fluid 13 extrudes the aluminum alloy profiles inside the external head 23 and discharges them outward through the gap between the intermediate head 21 and the external head 23, since the aluminum alloy profiles inside the external head 23 can only be discharged through the extrusion of the extrusion fluid 13, it is necessary to ensure that the volume of the transfer chamber is greater than the volume of the external head 23.

[0041] The extrusion fluid 13 is one of deionized water or softened water.

[0042] Using deionized water or softened water in the aluminum profile extrusion process is mainly to improve the stability and service life of the system. Ordinary water often contains hardness ions such as calcium and magnesium, which are extremely prone to scaling under high temperature and high pressure conditions, blocking pipelines and affecting fluid flow. At the same time, if the water contains corrosive components such as chloride ions, it may also accelerate the electrochemical corrosion of molds, containers, and sealing components such as aluminum, steel, and stainless steel, reducing the equipment life. In addition, deionized water and softened water have high purity and stable thermal conductivity, which can reduce the precipitation of bubbles and avoid system shocks caused by cavitation or local steam explosion. Therefore, using deionized water or softened water helps to achieve a more stable, clean, and controllable hydraulic pressure transmission and cooling environment.

[0043] Combined with the current actual needs, the above implementation method adopted in this application, the protection scope is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
