Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal processing, in particular to an aluminum profile extrusion forming die. BACKGROUND

[0002] With the improvement of people's demand, aluminum special-shaped parts enter people's field of vision. The aluminum special-shaped part refers to a complex geometric part formed by combining multiple simple metal parts and is widely used in various industries.

[0003] In the field of aluminum material processing, especially in the production of aluminum special-shaped parts, traditional methods such as stamping and casting are difficult to realize complex shapes and fine structures. Mechanical extrusion forming process gradually becomes an important and widely used technology due to its efficiency and precision. The extrusion forming technology is a method of applying a large pressure in a die to extrude a metal blank into a die cavity and solidify the part.

[0004] The existing aluminum profile extrusion forming die is mostly coated with lubricating liquid on the fixed die side to prevent the formed metal part from adhering, then the movable die and the fixed die are combined, and a certain amount of metal blank is poured into the extrusion cavity. After the metal blank is poured, the piston extrudes the metal blank into the combined die cavity. After the metal blank is cooled and formed, the movable die and the fixed die are separated and the formed metal part is separated from the fixed die. Then the metal part is pushed out by the pushing assembly and the work is repeated. Although the extrusion forming technology can manufacture metal parts with high precision and complex structure, a large amount of air is often left in the die cavity during the extrusion forming process of the existing special-shaped metal part. After the special-shaped metal part is extruded and formed, the special-shaped metal part contains bubbles. If the special-shaped metal part contains a large number of bubbles, the use performance of the special-shaped metal part will be seriously affected, which will lead to the need for rework and seriously affect the production efficiency of the metal part.

[0046] Linkage assembly 5 includes the communication groove of being set up on fixed mould 2, linkage rod 501 of sliding installation is equipped in the communication groove, third spring 502 is jointly installed between linkage rod 501 and communication groove, the inclined slot 503 of cooperation is equipped on horizontal rod 405 with linkage rod 501, first magnet 504 is embedded on linkage rod 501, and extrusion assembly 6 includes the extrusion cavity 601 of being set up on fixed mould 2, and the feeding opening 602 of being set up with extrusion cavity 601 communication is equipped on fixed mould 2, piston plate 603 of sliding installation is equipped in extrusion cavity 601, second magnet 604 of mutual repulsion is embedded on piston plate 603 with first magnet 504, the top wall of workstation 1 is fixedly installed with mounting bracket 605, the top wall of mounting bracket 605 is fixedly installed with electric slide rail 606, the electric slide rail 606 of sliding installation is equipped with mounting block 607, the bottom wall of mounting block 607 is fixedly installed with the electric telescopic rod 608 of the output end with movable mould 3 fixed connection, the side wall of mounting bracket 605 is fixedly installed with the hydraulic rod 609 of the output end with piston plate 603 fixed connection, movable mould 3 is equipped with the push-out assembly 12 of pushing out the metal piece after forming.

[0047] In use, the electric slide rail 606 first drives the moving mold 3 to move via the mounting block 607 and the electric telescopic rod 608, causing the moving mold 3 to close with the fixed mold 2 to form a mold cavity. Then, a certain amount of metal billet is poured into the extrusion cavity 601 through the feeding port 602. After the metal billet is poured in, the output end of the hydraulic rod 609 extends and drives the piston plate 603 to move along the extrusion cavity 601. During the movement of the piston plate 603, the metal billet in the extrusion cavity 601 can be squeezed into the mold cavity. After the metal billet cools and forms, the output end of the electric telescopic rod 608 retracts and drives the formed metal part upward through the moving mold 3. Then, the electric slide rail 606, through the mounting block 607, the electric telescopic rod 608, and the moving mold 3, brings the formed metal part to the designated position. Then, the output end of the electric telescopic rod 608 extends again and drives the moving mold 3 downward. Finally, the ejection assembly 12 ejects the formed metal part, thus achieving the purpose of extruding and forming aluminum irregular parts.

[0048] When the piston plate 603 compresses the metal billet into the mold cavity, excess air in the mold cavity flows to the outside through the exhaust port 401 on the vertical groove. Simultaneously, as the piston plate 603 moves, it causes the second magnet 604 to gradually approach the first magnet 504. Then, the repulsive force between the first magnet 504 and the second magnet 604 gradually increases. Under the action of this repulsive force, the first magnet 504 drives the connecting rod 501 to move upward. At this time, the third spring 502 is compressed and has a tendency to return to its original position. Then, as the connecting rod 501 moves upward, it gradually contacts the inclined surface of the inclined groove 503, and through the inclined surface of the inclined groove 503, it drives the horizontal rod 405 to move horizontally. Then, as the horizontal rod 405 moves, it drives the vertical rod 402 to move upward, and as the vertical rod 402 moves upward, it drives... As the sealing plate 403 moves downward, the second magnet 604 is positioned directly below the first magnet 504 after the airflow in the mold cavity is discharged. At this point, the repulsive force between the first magnet 504 and the second magnet 604 is at its maximum. This means that the connecting rod 501 drives the horizontal rod 405 to its maximum displacement. At this point, the top wall planes of the horizontal rod 405 and the vertical rod 402 are in contact with the bottom wall of the vertical rod 402. The vertical rod 402 drives the sealing plate 403 to block the exhaust port 401, causing the sealing plate 403 to reach its lowest point. Then, the bottom wall of the sealing plate 403 is on the same arc surface as the mold cavity. This effectively prevents a large amount of air from remaining in the mold cavity, which would cause the metal parts to contain a large number of air bubbles, resulting in poor metal part performance and requiring time for rework. This improves the production efficiency of metal parts.

[0049] When the metal piece is cooled and formed, the output end of the hydraulic rod 609 is retracted and drives the piston plate 603 to reset, and in the process of resetting the piston plate 603, the second magnet 604 is driven away from the first magnet 504, at this time the third spring 502 drives the connecting rod 501 to reset downward and is out of contact with the inclined groove 503, then the second spring 406 is stretched and drives the horizontal rod 405 to reset, in the process of resetting the horizontal rod 405, it is gradually out of contact with the vertical rod 402, at this time the first spring 404 is stretched and drives the vertical rod 402 to reset upward, in the process of resetting the vertical rod 402, the sealing plate 403 is driven to move upward, at this time the exhaust port 401 is in communication with the vertical groove again, which plays a role in preparing for work again, and at the same time the mold cavity on the movable mold 3 can be communicated with the outside through the vertical groove and the exhaust port 401, thereby facilitating the subsequent push-out assembly 12 to push out the metal piece.

[0050] As shown in Figure 3 , Figure 5 , Figure 6 , Figure 8 , the top wall of the fixed mold 2 is symmetrically provided with a sliding groove 701, a sliding block 702 is slidingly installed in the sliding groove 701, a cleaning rod 703 is fixedly installed at the top ends of the two sliding blocks 702, cleaning hairs 704 are fixedly installed on the bottom wall of the cleaning rod 703, and elastic pads 705 are jointly installed between the sliding block 702 and the sliding groove 701.

[0051] The top wall of the movable mold 3 is provided with a mounting groove, a collection box 706 is vertically slidingly installed in the mounting groove, and an elastic air bag 707 is jointly installed between the bottom wall of the collection box 706 and the mounting groove. A rotating rod 708 is rotatably installed on the collection box 706, and cleaning rods 709 are uniformly fixedly installed on the rotating rod 708.

[0052] A gear 801 is fixedly installed on the rotating rod 708, a rack 802 engaged with the gear 801 is fixedly installed on the mounting groove, a clockwork 803 is jointly installed between the gear 801 and the collection box 706, a rectangular groove 804 is formed in the rotating rod 708, a control groove is formed in the side wall of the sliding groove 701, a push block 805 is slidingly installed in the control groove, a pushing groove 806 cooperating with the sliding block 702 is formed in the push block 805, a fixed rod 807 slidingly cooperating with the rectangular groove 804 is fixedly installed on the push block 805, and a connecting spring 808 is jointly installed between the push block 805 and the control groove.

[0053] By adopting the above technical scheme, in the process that the output end of the electric telescopic rod 608 is retracted and drives the movable mold 3 to move upward, the movable mold 3 drives the horizontal rod 405 to move upward, and then the horizontal rod 405 gradually comes off the cleaning rod 703 in the process of moving upward, at this time, the elastic pad 705 is retracted and drives the sliding block 702 to slide along the sliding groove 701, the cleaning rod 703 is driven to move in the process that the sliding block 702 slides, and then the cleaning hair 704 is driven to move in the process that the cleaning rod 703 moves, and the debris remaining on the fixed mold 2 can be cleaned into the collecting box 706 in the process that the cleaning hair 704 moves, thereby avoiding that the debris remaining on the fixed mold 2 affects the quality of the next metal piece, further reducing the possibility of rework, and further improving the production efficiency of the metal piece.

[0054] In the process that the output end of the electric telescopic rod 608 is retracted and drives the movable mold 3 to move upward, the elastic air bag 707 gradually expands and drives the collecting box 706 to move upward, then the gear 801 is driven to move upward by the rotating rod 708 in the process that the collecting box 706 moves upward, and the gear 801 starts to rotate under the action of the rack 802, at this time, the spring 803 starts to store energy, then when the spring is in a free expansion state, the gear 801 comes off the rack 802, at the same time, after the gear 801 comes off the rack 802, the rectangular groove 804 on the rotating rod 708 comes into contact with the fixed rod 807, at this time, the connecting spring 808 expands and drives the fixed rod 807 to insert into the rectangular groove 804 through the push block 805, and in the process that the elastic pad 705 cleans the fixed mold 2 through the sliding block 702, the cleaning rod 703 and the cleaning hair 704, the sliding block 702 gradually comes into contact with the pushing groove 806 on the push block 805 and exerts a pushing force on the pushing groove 806, then the push block 805 drives the fixed rod 807 to move away from the rectangular groove 804 under the action of the pushing force, and when the elastic pad 705 is in a free expansion state, the cleaning rod 709 drives the cleaning hair 704 to be located directly above the collecting box 706, and at this time, the fixed rod 807 comes off the rectangular groove 804, at this time, the spring 803 expands and drives the rotating rod 708 to rotate through the gear 801, then the cleaning rod 709 is driven to rotate and the cleaning hair 704 is combed in the process that the rotating rod 708 rotates, and at the same time, the impurities adhered to the cleaning hair 704 can also be cleaned, thereby avoiding that the impurities are attached to the fixed mold 2 again, effectively reducing the possibility of rework of the metal piece, and further improving the production efficiency of the metal piece.

[0055] As Figure 5 , Figure 6 , Figure 7As shown, a hollow rod 901 is rotatably mounted on the rotating rod 708. Air holes 902 are evenly distributed on the hollow rod 901. A rectangular block 903 that slides with the mounting groove is fixedly mounted on the hollow rod 901. A connecting hole 904 that mates with the air hole 902 is evenly distributed on the rotating rod 708. A cavity 905 is formed on the elastic pad 705. An air inlet valve 906 with its input end communicating with the outside is inserted into the cavity 905. A first air pipe 907 communicating with the cavity 905 is provided on the hollow rod 901. A connecting component 10 that mates with the first air pipe 907 is provided on the fixed mold 2.

[0056] The connecting component 10 includes a connecting groove on a fixed mold 2, a round rod 101 is horizontally slidably installed in the connecting groove, a return spring 102 is installed between the round rod 101 and the connecting groove, and a groove 103 is opened on the round rod 101 to communicate with the first air pipe 907.

[0057] By adopting the above technical scheme, in the process of driving the movable mold 3 to close the mold by the electric sliding rail 606, the horizontal rod 405 on the movable mold 3 drives the cleaning rod 703 to move, and the elastic pad 705 is stretched through the cleaning rod 703 and the sliding block 702, and in the process of stretching the elastic pad 705, the cavity 905 inhales air from the outside through the air inlet valve 906, and then in the process of the elastic pad 705 driving the cleaning rod 703 to reset, the airflow in the cavity 905 is compressed and has a tendency to flow to the outside, and in the process of the elastic pad 705 driving the sliding block 702 to reset, the sliding block 702 gradually contacts the round rod 101 and exerts a pushing force on the round rod 101, and then under the action of the pushing force, the round rod 101 moves and presses the reset spring 102, and after the cleaning rod 709 drives the cleaning hair 704 to move to the collection box 706, the round rod 101 drives the groove 103 to communicate with the first air pipe 907, at this time, the airflow in the cavity 905 flows into the hollow rod 901 through the groove 103 and the first air pipe 907, and at the same time, in the process of rotating the rotating rod 708, the communication hole 904 is driven to rotate, when the communication hole 904 communicates with the air hole 902, the airflow in the hollow rod 901 blows to the cleaning hair 704 through the air hole 902 and the communication hole 904, thereby further improving the cleaning effect of the cleaning hair 704, and at the same time, the air hole 902 is arranged on the side wall of the hollow rod 901 away from the piston plate 603, and the end of the hollow rod 901 away from the gear 801 is fixedly installed with a rectangular block which is in sliding fit with the mounting groove, so that the hollow rod 901 is in rotating fit with the rotating rod 708, and the hollow rod 901 is in sliding fit with the fixed mold 2, so that the airflow always blows away from the mold cavity of the fixed mold 2, thereby the impurities which are not in contact with the cleaning hair 704 can hit the side wall of the collection box 706 and fall into the collection box 706, avoiding the airflow from driving the impurities to fall into the mold cavity of the fixed mold 2 again, effectively preventing the impurities from affecting the finished product quality of the metal part, thereby reducing the possibility of rework, and improving the production efficiency of the metal part.

[0058] As shown in Figure 3 , Figure 4 , the cavity 111 is arranged on the cleaning rod 703, the cavity 111 is uniformly provided with the hole 112 which is matched with the cleaning hair 704, the lubricating cavity 113 is arranged on the workbench 1, the lubricating cavity 113 is filled with lubricating liquid, the lubricating pipe 114 which is in communication with the cavity 111 is inserted into the lubricating cavity 113, the first one-way valve 115 which has an output end extending into the cavity 111 is inserted into the elastic air bag 707, and the second one-way valve 116 which has an input end in communication with the outside is inserted into the elastic pad 705.

[0059] By adopting the above technical solution, in order to avoid the molded metal parts adhering to the cavity of the fixed mold 2, workers usually need to manually apply lubricant to the cavity of the fixed mold 2 before mold closing. During the extension of the elastic airbag 707, the elastic airbag 707 draws air from the outside through the first one-way valve 115. Then, when the electric slider 702 drives the moving mold 3 to close with the fixed mold 2, the moving mold 3 pushes the cleaning rod 703 to reset through the horizontal rod 405. At the same time, the moving mold 3 contacts the inclined surface on the collection box 706 and drives the collection box 706 to move downward and reset. During the downward movement of the collection box 706... The elastic airbag 707 is compressed, and the gas inside the elastic airbag 707 flows into the lubrication chamber 113 through the second one-way valve 116, increasing the pressure inside the lubrication chamber 113. Under the action of the pressure, the lubricating fluid in the lubrication chamber 113 flows into the cavity 111 through the lubrication pipe 114 and adheres to the cleaning bristles 704 through the holes 112 on the cavity 111. When the cleaning bristles 704 pass through the mold cavity of the fixed mold 2, the lubricating fluid can be evenly applied to the mold cavity of the fixed mold 2, thus eliminating the need for workers to spend time manually applying the lubricating fluid to the mold cavity of the fixed mold 2, further improving the production efficiency of metal parts.

[0060] like Figure 3 As shown, the ejection assembly 12 includes an electric push rod 121 mounted on the moving mold 3. An installation plate 122 is fixedly mounted on the output end of the electric push rod 121. Ejection rods 123 are evenly fixedly mounted on the installation plate 122. A collection port is provided on the top wall of the worktable 1. A parts box 124 that cooperates with the collection port is detachably mounted on the bottom wall of the worktable 1.

[0061] By adopting the above technical solution, when the moving mold 3 moves the formed metal part to the top of the collection port, the user can control the output end of the electric push rod 121 to extend. Then, the output end of the electric push rod 121 drives the push rod 123 to apply a pushing force to the metal part through the mounting plate 122 and push the metal part into the collection port. Then, the metal part enters the parts box 124 through the collection port, which facilitates the user to collect the metal part.

[0062] like Figure 3 As shown, the inclined surface at the top of the vertical rod 402 is a smooth mirror surface.

[0063] During the process of the horizontal rod 405 driving the vertical rod 402 to move through the inclined surface at the top of the vertical rod 402, by making the inclined surface at the top of the vertical rod 402 a smooth mirror surface, the friction between the vertical rod 402 and the horizontal rod 405 can be reduced, thereby ensuring that the horizontal rod 405 drives the vertical rod 402 to move normally.

[0064] The use method is as follows: in use, the electric sliding rail 606 first drives the movable mold 3 to move through the mounting block 607 and the electric telescopic rod 608, and the movable mold 3 is combined with the fixed mold 2 to form a mold cavity, then a certain amount of metal billet is poured into the extrusion cavity 601 through the feeding opening 602, and when the pouring of the metal billet is completed, the output end of the hydraulic rod 609 is extended and drives the piston plate 603 to move along the extrusion cavity 601, the metal billet in the extrusion cavity 601 can be extruded into the mold cavity in the process of movement of the piston plate 603, then after the metal billet is cooled and formed, the output end of the electric telescopic rod 608 is retracted and drives the formed metal piece to move upwards through the movable mold 3, then the electric sliding rail 606 drives the formed metal piece to the specified position through the mounting block 607, the electric telescopic rod 608 and the movable mold 3, then the output end of the electric telescopic rod 608 is extended again and drives the movable mold 3 to move downwards, and then the push-out assembly 12 pushes out the formed metal piece; when the piston plate 603 extrudes the metal billet into the mold cavity, the excess air in the mold cavity flows to the outside through the exhaust port 401 on the vertical groove; after the metal piece is cooled and formed, the output end of the hydraulic rod 609 is retracted and drives the piston plate 603 to reset, the second magnet 604 is driven to move away from the first magnet 504 in the process of resetting of the piston plate 603, at this time, the third spring 502 drives the connecting rod 501 to reset downwards and disengage from the inclined groove 503, then the second spring 406 is extended and drives the horizontal rod 405 to reset, the horizontal rod 405 gradually disengages from the vertical rod 402 in the process of resetting of the horizontal rod 405, at this time, the first spring 404 is extended and drives the vertical rod 402 to reset upwards, the sealing plate 403 moves upwards in the process of resetting of the vertical rod 402, at this time, the exhaust port 401 is in communication with the vertical groove again, and plays a role of preparing for the next work, and the mold cavity on the movable mold 3 can be in communication with the outside through the vertical groove and the exhaust port 401, so that the metal piece can be pushed out by the push-out assembly 12.

[0065] The above merely illustrates the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes to the technical solution of the present application and the improved concept thereof within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application.
