[0002] Aluminum profile forming molds are important tools used to extrude or cast molten or semi-solid aluminum alloy materials through specific molds. They are widely used in construction, transportation, electronics and aerospace. Due to the excellent properties of aluminum, such as low density, high strength, corrosion resistance and easy recycling, it occupies an irreplaceable position in modern industry.
[0003] Currently, when casting aluminum profiles using existing aluminum profile forming molds, the aluminum profiles tend to remain inside the mold after forming, making it inconvenient for workers to quickly remove the formed aluminum profiles. This increases the complexity of the operation, and users still need to use tools to remove the formed aluminum material from the mold. Furthermore, the temperature of the formed aluminum material is still relatively high, and manual operation not only affects the processing efficiency of aluminum profiles but also poses certain dangers.
[0004] Therefore, a forming mold for aluminum profile processing is proposed. Summary of the Invention
[0005] The purpose of this invention is to provide a forming mold for aluminum profile processing. This application designs a demolding mechanism that can automatically demold the aluminum profile after it has been cast in the active mold and passive mold, so that the formed aluminum profile can quickly detach from the active mold and passive mold without human intervention. The demolding method includes two modes: vibration demolding and extrusion ejection demolding, in order to solve the problems mentioned in the background art.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.
[0031] Please see Figures 1 to 8 The present invention provides a technical solution:
[0032] A forming mold for aluminum profile processing includes an operating table 5 and a support leg 6 fixed to the lower end face of the operating table 5. A casting mold is movably connected to the upper end face of the operating table 5. The casting mold includes an active mold 1 and a passive mold 2. The adjacent surfaces of the active mold 1 and the passive mold 2 are designed with an open structure. The upper side of the adjacent surfaces of the active mold 1 and the passive mold 2 are provided with a casting port 3 that communicates with the internal cavity of the active mold 1 and the passive mold 2. A support frame 4 fixedly connected to the operating table 5 is provided on the front side of the active mold 1. An electric push rod 7 is fixedly connected to the support frame 4, and the output end of the electric push rod 7 is fixedly connected to the active mold 1. A demolding mechanism is provided inside the passive mold 2.
[0033] The internal cavity volume of the active mold 1 is smaller than that of the passive mold 2, so that the contact area between the formed aluminum profile and the inner wall cavity of the passive mold 2 is larger than that of the active mold 1. This allows the formed aluminum profile to remain inside the passive mold 2 when the active mold 1 is displaced, and then the demolding mechanism of the passive mold 2 is activated to perform the demolding operation. The maximum adjustment volume of the adjustment plate 18 shall not exceed the internal volume of the passive mold 2.
[0034] Specifically, the passive mold 2 is provided with a support frame 2 12 fixedly connected to the operating table 5 on its rear side. A guide post 11 passes through the support frame 2 12. The guide post 11 is movably connected to the support frame, and one end of the guide post 11 is fixedly connected to the passive mold 2. A spring is sleeved on the outer surface of the guide post 11 located between the support frame 2 12 and the passive mold 2. One end of the spring is fixedly connected to the support frame 2 12, and the other end is fixedly connected to the passive mold 2.
[0035] By adopting the above technical solution, the formed aluminum profile remains in the internal cavity of the passive mold 2, and then, under the action of the return spring 13 outside the guide post 11, the passive mold 2 carries the formed aluminum profile in the reverse displacement.
[0036] Specifically, the upper surface of the operating table 5 is symmetrically provided with a sliding groove 15 located below the passive mold 2. Elastic sheets 20 are fixedly distributed at equal intervals in the sliding groove 15. The elastic sheets 20 are made of elastic metal material, and teeth 23 are movably connected between the elastic sheets 20. The tops of several teeth 23 are fixedly connected to the passive mold 2.
[0037] By adopting the above technical solution, during the process of pouring and moving, the teeth 23 at the bottom of the passive mold 2 are displaced in the slide 15 and continuously squeeze the elastic sheet 20. The elastic sheet 20 deforms and collides with the teeth 23, generating vibration. The vibration force is transmitted to the cavity between the passive mold 2 and the active mold 1, which can accelerate the flow of aluminum liquid and expel air. Then, it remains still for a period of time to wait for the internal aluminum profile to cool and form.
[0038] Specifically, an adjusting plate 18 is movably connected inside the active mold 1, and a threaded rod 8 is symmetrically arranged on the front end of the active mold 1. The rear end of the threaded rod 8 extends through the active mold 1 and into the active mold 1 to be rotatably connected to the adjusting plate 18. The threaded rod 8 is rotatably connected to the active mold 1. An adjusting nut 9 is threadedly connected to the outside of the threaded rod 8 located on the front side of the active mold 1, and scale lines are provided on the surface of the threaded rod 8.
[0039] By adopting the above technical solution, this application does not require changing different molds for aluminum profiles of the same model but different thicknesses. The user only needs to turn the adjusting nut 9 to drive the threaded rod 8 to move inside the cavity of the active mold 1, thereby driving the adjusting plate 18 to move, which can adjust the internal volume of the active mold 1. The user can calculate the volume by observing the scale on the surface of the threaded rod 8.
[0040] Specifically, the passive mold 2 is rotatably connected to an actuating plate 16. A rotating shaft 17 is fixedly connected to the middle of both sides of the actuating plate 16. The other end of the rotating shaft 17 passes through the passive mold 2 and extends to the outside of the passive mold 2. Guide side plates 10 are fitted to both sides of the passive mold 2. A guide groove 14 is formed on the inner wall of the guide side plate 10 at a position corresponding to the rotating shaft 17. A rack 19 is fixedly connected to the lower end face of the middle of the guide groove 14. A gear 21 is meshed on the rack 19. A connecting rod 22 is rotatably connected to the middle of the gear 21. One end of the connecting rod 22 is fixedly connected to the rotating shaft 17. A one-way ratchet structure is provided between the gear 21 and the connecting rod 22. The gear 21 rotates counterclockwise to rotate on its own axis, and rotates clockwise to self-lock and drive the connecting rod 22 to rotate. A torsion spring is provided at the point where the rotating shaft 17 passes through and connects to the passive mold 2. One end of the torsion spring is fixed to the passive mold 2, and the other end is fixed to the rotating shaft 17.
[0041] By adopting the above technical solution,
[0042] Working principle:
[0043] First, the active mold 1 and the passive mold 2 are driven to close by the output end of the electric push rod 7 connected to the active mold 1. Then, the pouring pipe of the external pouring machine connects to the pouring port 3 on the active mold 1 and the passive mold 2, and then pours molten aluminum into the cavity between the active mold 1 and the passive mold 2 through the pouring port 3. During the pouring process, the electric push rod 7 continues to push the active mold 1 towards the passive mold 2. In order to maintain the stability of the movement of the active mold 1, a slide rail can be added between the active mold 1 and the operating table 5. When the electric push rod 7 drives the active mold 1 to move, it also squeezes the passive mold 2 to move towards the support frame 2 12. The passive mold 2 can maintain a stable displacement by connecting with the guide side plate 10, the bottom slide groove 15, and the rear guide column 11 to the support frame 2 12. During the process of pouring and moving at the same time, the teeth 23 at the bottom of the passive mold 2 move in the slide groove 15 and continuously squeeze the elastic plate 20. The elastic plate 20 deforms elastically and collides with the teeth 23, generating vibration. The vibration force is transmitted The aluminum liquid is fed into the cavity between the passive mold 2 and the active mold 1, which can accelerate the flow of aluminum liquid and expel air. Then, it is left to stand still for a period of time to allow the internal aluminum profile to cool and form. Subsequently, the electric push rod 7 retracts, pulling the active mold 1 and the passive mold 2 apart. The active mold 1 resets, and the formed aluminum profile stays in the internal cavity of the passive mold 2. Then, under the action of the reset spring 13 outside the guide post 11, the passive mold 2 carries the formed aluminum profile and moves in the opposite direction. At this time, the bottom tooth 23 contacts the elastic plate 20 again to generate vibration and achieve vibration demolding. At the same time, the gear 21 in the guide groove 14 on both sides of the passive mold 2 contacts the rack 19. Under the action of the one-way ratchet, the connecting rod 22 is driven to rotate, which drives the rotating shaft 17 to rotate. This causes the actuating plate 16 inside the passive mold 2 to rotate 90 degrees to squeeze the formed aluminum material inside, causing it to detach from the passive mold 2 and achieve a complete demolding operation. When the gear 21 no longer contacts the rack 19, under the action of the torsion spring, the actuating plate 16 resets and waits for the next pouring operation.
[0044] For aluminum profiles of the same type but different thicknesses, this application does not require changing different molds. The user only needs to turn the adjusting nut 9 to drive the threaded rod 8 to move inside the cavity of the active mold 1, thereby driving the adjusting plate 18 to move, which can adjust the internal volume of the active mold 1. The user can calculate the volume by observing the scale on the surface of the threaded rod 8.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
