Description

Technical Field

[0001] This utility model belongs to the field of aluminum extrusion machine technology, and in particular relates to a waste aluminum demolding device for aluminum profile extrusion molds. Background Technology

[0002] When using an aluminum pressing machine to process aluminum molds, a fixed mold and a stamping device need to work together. The aluminum raw material is placed on the top of the fixed mold, and the aluminum raw material is coaxial with the center of the stamping device. The aluminum pressing machine starts the stamping device, and the stamping head moves downward to squeeze the aluminum raw material. The scrap aluminum blocks enter the collection box through the discharge port of the fixed mold. The workers then remove the aluminum mold that has been processed from the top of the fixed mold.

[0003] Because the aluminum pressing machine lacks a demolding device, the bottom of the stamping head will stick to the scrap aluminum during the processing of aluminum raw materials. That is, the high activity and softness of aluminum cause metal-to-metal adhesion to the surface of the stamping head under high pressure and high temperature. During the rising process of the stamping head, it will cause scratches on the inner wall of the formed aluminum die, affecting the subsequent stamping operation of the stamping head, and even causing damage to the stamping head. Therefore, a new scrap aluminum demolding device for aluminum profile extrusion dies is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a waste aluminum demolding device for aluminum profile extrusion molds. Through the mutual cooperation between components such as the linkage mounting shell, ejector block and linkage mechanism, after the aluminum mold stamping is completed, the ejector block squeezes the waste aluminum block from the side, preventing the waste aluminum block from sticking to the bottom of the stamping equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model is a waste aluminum demolding device for aluminum profile extrusion molds, including an aluminum pressing machine body 1, a fixed mold body 2, a stamping device 3, an aluminum mold 4, and a collection box 5. The fixed mold body 2 is fixedly connected to the aluminum pressing machine body 1. The stamping device 3, which is fixedly connected to the aluminum pressing machine body 1, is located above the fixed mold body 2. The aluminum mold 4 is slidably connected to the top of the fixed mold body 2. The bottom of the stamping device 3 is slidably connected to the aluminum mold 4. Waste aluminum blocks are located inside the fixed mold body 2 below the aluminum mold 4. The collection box 5, which is slidably connected to the aluminum pressing machine body 1, is located below the fixed mold body 2. A linkage mounting shell 6 is symmetrically fixedly connected to the fixed mold body 2. The interior of the linkage mounting shell 6 is connected to the surface of the fixed mold body 2. An ejector pin block 7 is slidably connected inside the linkage mounting shell 6. One end of the ejector pin block 7 passes through the interior of the fixed mold body 2, and the other end of the ejector pin block 7 contacts the surface of the waste aluminum block. A linkage mechanism for controlling the reciprocating movement of the ejector pin block 7 is provided inside the linkage mounting shell 6.

[0022] By adopting the above technical solution, the aluminum raw material is placed on the top of the fixed mold body. The main body of the aluminum pressing machine controls the stamping equipment to start. The stamping equipment descends to stamp the aluminum raw material. The formed aluminum mold is located on the top of the fixed mold body. The top of the scrap aluminum block sticks to the bottom of the stamping equipment. When the stamping equipment descends, the linkage mechanism controls the ejector pin block to slide along the inside of the linkage mounting shell. One end of the ejector pin block presses the surface of the scrap aluminum block to prevent the scrap aluminum block from sticking to the bottom of the stamping equipment.

[0023] The linkage mechanism includes a linkage rod 8 rotatably connected inside the linkage mounting housing 6. The threaded surface of the linkage rod 8 meshes with the inside of the ejector block 7. A lifting frame 9 is provided on one side of the ejector block 7 and is slidably connected to the inside of the linkage mounting housing 6. One end of the linkage rod 8 passes through the inside of the lifting frame 9. A linkage gear 10 is fixedly connected to the linkage rod 8. A linkage rack 11 that meshes with the linkage gear 10 is fixedly connected to the inner wall of the lifting frame 9. An L-shaped extrusion rod 12 is symmetrically fixedly connected to the stamping equipment 3. The bottom end of the L-shaped extrusion rod 12 contacts the upper surface of the lifting frame 9.

[0024] By adopting the above technical solution, when the stamping equipment moves downward, it drives the L-shaped extrusion rod to move downward. The bottom end of the L-shaped extrusion rod contacts the upper surface of the lifting frame, which moves the lifting frame downward along the inside of the linkage mounting shell. The linkage rack controls the linkage gear to rotate, which drives the linkage rod to rotate inside the linkage mounting shell, thereby controlling the ejector pin block to move towards the inside of the fixed mold body.

[0025] The lower surface of the lifting frame 9 is symmetrically and fixedly connected with a return spring 13, which is fixedly connected to the inner wall of the linkage mounting shell 6.

[0026] By adopting the above technical solution, when the lifting frame moves downward, the compression return spring contracts, and when the stamping equipment returns to its original position and rises, the L-shaped compression rod no longer compresses the lifting frame, the return spring returns to its original position and opens, driving the lifting frame and the ejector pin block to return to their original positions.

[0027] A rotating rod 14 is rotatably connected to the fixed mold body 2. A separation guide groove 15 located below the stamping equipment 3 is opened on the surface of the fixed mold body 2. A separation plate 16 is fixedly connected to the rotating rod 14 and slides through the separation guide groove 15. The upper surface of the separation plate 16 contacts the bottom end of the stamping equipment 3, and the lower surface of the separation plate 16 contacts the top end of the waste aluminum block.

[0028] By adopting the above technical solution, the rotating rod is rotated, and the separation plate on the surface of the rotating rod enters the separation guide groove to separate the stamping equipment and the scrap aluminum block that are in a bonded state. With the help of the ejector pin block, it can effectively prevent the stamping equipment and the scrap aluminum block from bonding and separate them quickly.

[0029] A protective seat 17 is provided on one side of the rotating rod 14 and is fixedly connected to the fixed mold body 2. A drive motor 18 is fixedly connected to the protective seat 17. The output shaft of the drive motor 18 is rotatably connected to the fixed mold body 2. The surface of the rotating rod 14 is connected to the output shaft of the drive motor 18 through bevel gear meshing.

[0030] By adopting the above technical solution, the drive motor inside the protective seat is started, and the bevel gear on the output shaft of the drive motor contacts the bevel gear on the surface of the rotating rod, controlling the rotating rod to rotate on the fixed mold body, thus providing drive for the movement of the separation plate.

[0031] Below the waste aluminum block is an anti-blocking cylinder 19 located inside the fixed mold body 2. The bottom end of the rotating rod 14 is fixedly connected to a synchronous gear 20 that is rotatably connected inside the fixed mold body 2. Synchronous tooth blocks 21 that mesh with the synchronous gear 20 are fixedly connected at equal intervals on the surface of the anti-blocking cylinder 19.

[0032] By adopting the above technical solution, when the rotating rod rotates, the bottom synchronous gear contacts the synchronous tooth block on the surface of the anti-blocking cylinder, controlling the anti-blocking cylinder to rotate inside the fixed mold body, preventing the waste aluminum block in the unloading process from being squeezed and blocked inside the fixed mold body.

[0033] The top of the anti-blocking cylinder 19 is fixedly connected to a first annular plate 22 that is rotatably connected to the inner wall of the fixed mold body 2. The bottom of the synchronous tooth block 21 is provided with a second annular plate 23 that is fixedly connected to the anti-blocking cylinder 19. The second annular plate 23 is rotatably connected to the inner wall of the fixed mold body 2.

[0034] By adopting the above technical solution, when the anti-blocking cylinder rotates, the first annular plate and the second annular plate rotate on the inner wall of the fixed mold body, ensuring the stable rotation of the anti-blocking cylinder.

[0035] The inner wall of the anti-blocking cylinder 19 is provided with rolling holes 24 at equal intervals. Steel balls 25 are slidably connected inside the rolling holes 24, and the surface of the steel balls 25 is in contact with the surface of the waste aluminum block.

[0036] By adopting the above technical solution, when the waste aluminum block enters the anti-blocking cylinder, it will come into contact with the surface of the steel ball, which facilitates its rapid discharge. At the same time, due to the rolling of the steel ball, the phenomenon of squeezing and blocking is effectively prevented.

[0037] The blanking hole is matched with the aluminum mold. That is, the fixed mold body of the corresponding size is selected according to the aluminum mold of different sizes to provide support for the aluminum mold, thereby providing a stable and reliable support for the aluminum mold, so that the aluminum mold is stably stressed during the stamping process and avoids displacement or damage to the aluminum mold during the stamping process.

[0038] A specific application of this embodiment is as follows: aluminum raw material is placed at the top of the fixed mold body 2. The aluminum pressing machine body 1 controls the stamping equipment 3 to start. The stamping equipment 3 descends to stamp the aluminum raw material. The formed aluminum mold 4 is located at the top of the fixed mold body 2. The top of the scrap aluminum block sticks to the bottom of the stamping equipment 3. When the stamping equipment 3 moves downward, it drives the L-shaped extrusion rod 12 to move downward. The bottom of the L-shaped extrusion rod 12 contacts the upper surface of the lifting frame 9, causing the lifting frame 9 to move downward along the inside of the linkage mounting shell 6. The linkage rack 11 controls the linkage gear 10 to rotate, causing the lifting frame 9 to rotate inside the linkage mounting shell 6. The lifting frame 9 controls the ejector pin block 7 to move towards the inside of the fixed mold body 2. One end of the ejector pin block 7 presses the surface of the scrap aluminum block to prevent the scrap aluminum block from sticking to the bottom of the stamping equipment 3. When the lifting frame 9 moves downward, the compression return spring 13 contracts. When the stamping equipment 3 returns to its original position and rises, the L-shaped extrusion rod 12 no longer presses the lifting frame 9, and the return spring 13 returns to its original position and opens, causing the lifting frame 9 and the ejector pin block 7 to return to their original positions.

[0039] A specific application of this embodiment is as follows: The drive motor 18 inside the protective seat 17 is activated. The output shaft bevel gear of the drive motor 18 contacts the bevel gear on the surface of the rotating rod 14, controlling the rotating rod 14 to rotate on the fixed mold body 2. The separation plate 16 on the surface of the rotating rod 14 enters the separation guide groove 15, separating the stamping equipment 3 and the scrap aluminum block that are in a bonded state. With the help of the ejector pin block 7, it can effectively prevent the stamping equipment 3 and the scrap aluminum block from bonding and quickly separate them. When the rotating rod 14 rotates, the bottom synchronous gear 20 contacts the synchronous tooth block 21 on the surface of the anti-blocking cylinder 19, controlling the anti-blocking cylinder 19 to rotate inside the fixed mold body 2, preventing the scrap aluminum block from being squeezed and blocked inside the fixed mold body 2 during the material feeding process. When the anti-blocking cylinder 19 rotates, the first annular plate 22 and the second annular plate 23 rotate on the inner wall of the fixed mold body 2, ensuring the stable rotation of the anti-blocking cylinder 19. When the scrap aluminum block enters the anti-blocking cylinder 19, it will contact the surface of the steel ball 25, facilitating its rapid feeding. At the same time, due to the rolling of the steel ball 25, the phenomenon of squeezing and blocking is effectively prevented.
