Description

Technical Field

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: melting, extrusion and coloring. Among them, coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer and other processes.

[0003] The existing patent (publication number: CN212598012U) discloses an aluminum profile extrusion mold for doors and windows, which belongs to the field of aluminum profile technology, including a panel, the top of which is fixedly connected to two connecting modules, the tops of the two connecting modules are fixedly connected to two connecting buckles, the top of the panel is provided with a fluid inlet, the fluid inlet is located on the opposite side of the two connecting modules, and the panel is provided with a diversion cavity inside, the diversion cavity is located at the bottom of the fluid inlet and is connected to the inside.

[0004] The above-mentioned comparative document points out that in this device and this utility model, the metal fluid enters the diversion chamber through the fluid inlet, and the diversion chamber can make the metal fluid flow to the inside of the bottom plate at a uniform speed. When the extrusion is completed and needs to be separated, the horizontal plate is lifted and the rotating rod is rotated ninety degrees, and the two vertical rods are inserted into the clamping holes on the front and rear sides. At this time, the strip block is not restricted by the clamping block and can move up and down freely, and then the panel can be moved up, which solves the previous problem of uneven metal fluid flow rate and gap between the devices. However, when the device extrude the aluminum profile, the panel is connected to the extrusion device and the downward force is provided by the extrusion device to extrude the aluminum. Since the force applied to the aluminum is only downward pressure, it is easy to cause uneven extrusion of the aluminum, which may cause defects in the formed aluminum profile. Utility Model Content

Since the force applied to the aluminum material is only downward pressure, it is easy to cause uneven extrusion of the aluminum material, which may cause defects in the aluminum profile after forming.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: an aluminum profile extrusion mold for doors and windows, comprising an outer shell and an upper plate, wherein both sides of the inner part of the outer shell are rotatably connected to a rotating shaft, and the outer walls of the two rotating shafts are rotatably connected to gears, slots are provided on both sides of the upper end of the outer shell, a lower mold is slidably connected to the inner part of the outer shell, and a first tooth plate is fixedly connected to both sides of the lower mold.

The downward force applied by the upper plate is converted into an upward force through the rotation of the gear and transmitted to the lower mold through the first tooth plate, so that the lower mold rises through the rotation of the gear to apply an upward force to the aluminum material in the lower mold, which cooperates with the downward force generated by the power device, thereby extruding the aluminum material, and making the sealing effect between the upper plate and the lower mold better, thereby reducing the probability of defects in the formed aluminum profile.

[0013] Furthermore, the upper end of the lower mold is provided with four first positioning holes, and the upper end of the shell is provided with four second positioning holes.

[0017] Furthermore, heat dissipation grooves are provided on both sides of the shell.

[0018] Through the above scheme, the heat sink is designed to dissipate heat from the lower die during the forming of the aluminum material.

[0019] Furthermore, the two gears are respectively meshed with the first gear plate and the second gear plate.

[0020] Through the above solution, the second tooth plate moves downward and meshes with the gear, thereby driving the gear to rotate and drive the first tooth plate to lift upward.

[0021] Furthermore, the two second tooth plates are both slidably disposed inside the slot.

[0022] Through the above solution, the slot is arranged to enable the second tooth plate to slide in the housing.

A lower mold 5 is slidably connected inside the shell 1. Both sides of the lower mold 5 are fixedly connected with a first tooth plate 6. The lower mold 5 is lifted by rotating the first tooth plate 6 through the gear 3. Second tooth plates 8 are fixedly connected on both sides of the bottom end of the upper plate 7. Connecting modules 9 are fixedly connected on both sides of the upper end of the upper plate 7. The connecting module 9 is used to connect a power device.

[0033] See also Figure 2 and Figure 3 An exhaust hole 10 is provided at the upper end of the upper plate 7, and the exhaust hole 10 is used to exhaust the air inside the lower mold 5. A feed funnel 11 is fixedly connected to the upper plate 7, and an upper mold 12 is fixedly connected to the bottom end of the upper plate 7. A distribution pipe 13 is fixedly provided inside the upper mold 12. The feed funnel 11 is used to facilitate the metal fluid to enter the lower mold 5, and the metal fluid can be guided to the two sides of the lower mold 5 respectively through the distribution pipe 13. Four first positioning columns 14 and four second positioning columns 15 are fixedly connected to the bottom end of the upper plate 7, and the first positioning columns 14 and the second positioning columns 15 are used to position the upper plate 7.

[0034] See also Figure 1 , Figure 3 and Figure 4Four first positioning holes 16 are provided at the upper end of the lower mold 5, and four second positioning holes 17 are provided at the upper end of the shell 1. The first positioning holes 16 are used to position the lower mold 5, and the second positioning holes 17 are used to position the shell 1. The four first positioning posts 14 are slidably arranged inside the first positioning holes 16, and the second positioning posts 15 are slidably arranged inside the second positioning holes 17. The first positioning posts 14 are slidably arranged inside the first positioning holes 16 to position the upper mold 12 and the lower mold 5, and the second positioning posts 15 are slidably arranged inside the second positioning holes 17 to position the upper plate 7 and the shell 1. Heat dissipation grooves 18 are provided on both sides of the shell 1. The heat dissipation grooves 18 are designed to dissipate heat for the lower mold 5 during aluminum forming. The two gears 3 are respectively meshed with the first tooth plate 6 and the second tooth plate 8. The second tooth plate 8 moves downward and drives the gear 3 to rotate through meshing with the gear 3, which will drive the first tooth plate 6 to lift upward. The two second tooth plates 8 are slidably arranged inside the slot 4, and the slot 4 is set to enable the second tooth plate 8 to slide in the shell 1.

[0035] In this embodiment, the aluminum profile extrusion mold for doors and windows can be realized by setting the first tooth plate 6, the gear 3 and the second tooth plate 8. When the aluminum material is extruded, the power device applies a downward force to the upper plate 7 to make it descend, and the two second tooth plates 8 at the bottom of the upper plate 7 drive the gear 3 to rotate. The downward force applied by the upper plate 7 is converted into an upward force through the rotation of the gear 3 and transmitted to the lower mold 5 through the first tooth plate 6, so that the lower mold 5 rises through the rotation of the gear 3, exerting an upward force on the aluminum material in the lower mold 5, cooperating with the downward force generated by the power device, thereby extruding the aluminum material, and making the sealing effect between the upper plate 7 and the lower mold 5 better, thereby reducing the probability of defects in the formed aluminum profile.

[0036] It should be noted that the first tooth plate 6, the gear 3 and the second tooth plate 8 are all made of high-carbon steel. The high-carbon steel has high hardness, excellent wear resistance, and outstanding elasticity and toughness.

[0037] The working principle of the above embodiment is:

[0038] First, the aluminum material to be extruded is placed in the feed hopper 11, and the power device connected to the connection module 9 is started. The power device will generate a downward force, which is applied to the upper plate 7, causing it to begin to descend. As the upper plate 7 descends, the two second tooth plates 8 at its bottom will enter the slot 4 and mesh with the gear 3. When the second tooth plates 8 descend, they will drive the gear 3 to rotate. The rotation of the gear 3 will convert the downward force applied by the upper plate 7 into an upward force, and transmit it to the lower mold 5 through the first tooth plate 6. Due to the rotation of the gear 3, the lower mold 5 will rise, exerting an upward force on the aluminum material in the lower mold 5. At the same time, the power device continues to exert downward force. The cooperation of these two forces will extrude the aluminum material. During the extrusion process, the exhaust hole 10 will exhaust the air inside the lower mold 5, and the setting of the feed funnel 11 and the material distribution pipe 13 ensures that the metal fluid can flow smoothly into the lower mold 5 and is guided to the two sides of the lower mold 5 through the material distribution pipe 13. Under the action of the heat dissipation grooves 18 on both sides of the shell 1, the lower mold 5 dissipates heat during the aluminum forming process. The first positioning column 14 and the second positioning column 15 are slidably arranged in the first positioning hole 16 and the second positioning hole 17 respectively to ensure the correct positioning between the upper plate 7, the lower mold 5 and the shell 1. This also helps to maintain the sealing effect between the upper mold 12 and the lower mold 5.
