Description

Technical Field

[0001] This utility model relates to the field of vehicle parts processing technology, specifically a magnesium-aluminum alloy mold for vehicle parts. Background Technology

[0002] Vehicle parts are the various units that make up a car and the products that serve the car. Taking the car body as an example, some parts such as the car body are usually die-cast from magnesium-aluminum alloy, and molds are used in the processing.

[0003] After vehicle parts are processed and formed, they need to be demolded. The existing demolding method is to apply pressure directly to the mold to push the vehicle parts out directly to achieve the demolding effect. However, this hard ejection method is very easy to damage the vehicle parts, causing creases on the surface, which in turn affects the molding effect of the automotive parts. Utility Model Content

[0004] The purpose of this utility model is to provide a magnesium-aluminum alloy mold for vehicle parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A magnesium-aluminum alloy mold for vehicle parts includes a lower mold, an upper mold, and a forming cavity. The upper mold is located on top of the lower mold, and the forming cavity is opened on top of the lower mold. A transmission groove is opened inside the lower mold, and an ejector plate is provided inside the transmission groove. An ejector rod is fixedly connected to the top of the ejector plate, and the top of the ejector rod extends through the interior of the forming cavity.

[0007] A transmission mechanism is fixedly installed on one side of the lower mold and can control the ejector rod to lift and push out the molded vehicle parts;

[0008] The transmission mechanism includes a motor fixedly mounted on one side of the lower mold. The output end of the motor extends into the interior of the transmission groove and is fixedly connected to a missing gear. A transmission gear is provided at the bottom of the missing gear. A transmission rod is fixedly connected to one side of the transmission gear. A first bevel gear is fixedly connected to one end of the transmission rod. A second bevel gear is meshed with the top of the first bevel gear. A threaded rod is fixedly connected to the top of the second bevel gear. A linkage block is drivenly connected to the surface of the threaded rod. A buffer mechanism is provided at the connection between the linkage block and the ejector plate.

[0009] Preferably, the buffer mechanism includes a telescopic sleeve fixedly connected to the top of the linkage block, a spring fixedly connected to the inner wall of the telescopic sleeve, a buffer block fixedly connected to the top of the spring, a buffer rod fixedly connected to the top of the buffer block, the top of the buffer rod extending through to the top of the telescopic sleeve and fixedly connected to the bottom of the ejector plate.

[0010] Preferably, the spring has a limiting post inside, and the bottom of the limiting post is fixedly connected to the inner wall of the telescopic sleeve.

[0011] Preferably, sliding blocks are fixedly connected to both sides of the ejector plate, and the inner wall of the transmission groove is provided with a sliding groove that cooperates with the sliding blocks.

[0012] Preferably, one side of the transmission gear is rotatably connected to the inner wall of the transmission groove via a first bearing, and the bottom of the second bevel gear is rotatably connected to the inner wall of the transmission groove via a second bearing.

[0013] Preferably, the top of the linkage block is provided with a threaded hole, which is used in conjunction with the threaded rod.

[0014] Preferably, the number of ejector rods is several, and they are evenly distributed on the top of the ejector plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, by setting a transmission mechanism, enables the missing gear to rotate after the automotive parts are formed in the molding cavity by starting the motor. When a toothed segment of the missing gear contacts the transmission gear, it will drive the transmission gear, transmission rod, and first bevel gear to rotate around the first rotating shaft. Since the first bevel gear and the second bevel gear mesh, they will drive the second bevel gear and the threaded rod to rotate around the second bearing. While the threaded rod rotates, its external thread will squeeze the internal thread of the threaded hole, causing the linkage block to move upward. The linkage block will drive the telescopic sleeve, buffer block, and buffer rod to move upward, and at the same time drive the ejector plate and ejector rod at the top of the buffer rod to move upward. Multiple ejector rods evenly squeeze the automotive parts, thus achieving the effect of ejection and demolding. At the same time, every time the missing gear rotates one revolution and contacts the transmission gear, the ejector rod rises a section to eject the automotive parts, effectively avoiding damage to the automotive parts.

[0017] 2. By setting up a buffer mechanism, this utility model can cause the ejector plate to move downward under pressure when the ejector rod comes into contact with the vehicle parts. At the same time, the buffer rod and buffer block will move downward. The buffer block will squeeze the spring, and the spring's reaction force will achieve the buffering effect, thus avoiding damage to the vehicle parts during ejection.

[0018] In this invention, a transmission mechanism is provided to allow the ejector rod to intermittently eject the molded vehicle parts, thus preventing damage. At the same time, when the ejector rod contacts the vehicle parts, the ejector plate will move downwards due to pressure, which in turn will drive the buffer rod and buffer block to move downwards. The buffer block will compress the spring, and the spring's reaction force will achieve a buffering effect. Attached Figure Description

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] Example 1:

[0028] A magnesium-aluminum alloy mold for vehicle parts includes a lower mold 1, an upper mold 2, and a forming cavity 3. The upper mold 2 is located on top of the lower mold 1, and the forming cavity 3 is opened on top of the lower mold 1. A transmission groove 4 is opened inside the lower mold 1, and an ejector plate 5 is provided inside the transmission groove 4. An ejector rod 6 is fixedly connected to the top of the ejector plate 5, and the top of the ejector rod 6 penetrates into the interior of the forming cavity 3.

[0029] The transmission mechanism is fixedly installed on one side of the lower mold 1 and can control the ejector rod 6 to lift and push out the molded vehicle parts.

[0030] The transmission mechanism includes a motor 7 fixedly mounted on one side of the lower mold 1. The output end of the motor 7 extends through the interior of the transmission groove 4 and is fixedly connected to a missing gear 8. A transmission gear 9 is provided at the bottom of the missing gear 8. A transmission rod 10 is fixedly connected to one side of the transmission gear 9. A first bevel gear 11 is fixedly connected to one end of the transmission rod 10. A second bevel gear 12 is meshed with the top of the first bevel gear 11. A threaded rod 13 is fixedly connected to the top of the second bevel gear 12. A linkage block 14 is connected to the surface of the threaded rod 13. A buffer mechanism is provided at the connection between the linkage block 14 and the ejector plate 5.

[0031] In this embodiment, considering that existing mold demolding methods generally involve directly applying pressure to the mold to eject the vehicle parts, this forceful ejection method is prone to damaging the vehicle parts, causing surface creases and affecting the molding effect of the automotive parts, a transmission mechanism is designed. After the automotive parts are molded in the molding cavity 3, the starting motor 7 drives the missing gear 8 to rotate. When a toothed segment of the missing gear 8 contacts the transmission gear 9, it drives the transmission gear 9, transmission rod 10, and first bevel gear 11 to rotate around the first rotating shaft. Since the first bevel gear 11 and the second bevel gear 12 mesh... Therefore, the second bevel gear 12 and the threaded rod 13 will rotate around the second bearing 23. While the threaded rod 13 rotates, its external thread will squeeze the internal thread of the threaded hole 24, causing the linkage block 14 to move upward. The linkage block 14 will drive the telescopic sleeve 15, the buffer block 17 and the buffer rod 18 to move upward. At the same time, it will drive the ejector plate 5 and the ejector rod 6 at the top of the buffer rod 18 to move upward. The multiple ejector rods 6 will evenly squeeze the car parts, thus achieving the effect of ejection and demolding. At the same time, whenever the missing gear 8 rotates one revolution and contacts the transmission gear 9, the ejector rod 6 will rise a section to eject the car parts, effectively avoiding damage to the car parts.

[0032] Sliding blocks 20 are fixedly connected to both sides of the ejector plate 5, and a sliding groove 21 that cooperates with the sliding blocks 20 is opened on the inner wall of the transmission groove 4.

[0033] In this embodiment, by setting the sliding block 20 and the sliding groove 21, when the threaded rod 13 rotates to drive the linkage block 14, the linkage block 14, the ejector plate 5 and the ejector rod 6 and other structures can only move along the trajectory of the sliding block 20 and the sliding groove 21, thereby improving their stability during movement.

[0034] One side of the transmission gear 9 is rotatably connected to the inner wall of the transmission groove 4 via the first bearing 22, and the bottom of the second bevel gear 12 is rotatably connected to the inner wall of the transmission groove 4 via the second bearing 23.

[0035] In this embodiment, by setting the first bearing 22 and the second bearing 23, the first bevel gear 11 and the second bevel gear 12 can be restricted to always be in a meshing state, which plays a supporting role and at the same time improves the smoothness of their rotation process.

[0036] The top of the linkage block 14 is provided with a threaded hole 24, which is used in conjunction with the threaded rod 13.

[0037] In this embodiment, by setting a threaded hole 24, the external thread on the surface of the threaded rod 13 will press against the internal thread of the threaded hole 24 while the threaded rod 13 rotates, causing the linkage block 14 to move upward. The linkage block 14 will drive the telescopic sleeve 15, buffer block 17 and buffer rod 18 and other structures to move upward, thus playing a transmission role.

[0038] There are several ejector rods 6, which are evenly distributed on the top of the ejector plate 5.

[0039] In this embodiment, by setting up several ejector rods 6, the vehicle parts can be squeezed simultaneously by multiple ejector rods 6, thereby increasing the force-bearing area and effectively avoiding damage to the vehicle parts.

[0040] Example 2:

[0041] Based on Embodiment 1, in this embodiment, the transmission mechanism can control the ejector rod 6 to slowly move upward to eject the vehicle parts, thus avoiding damage to the vehicle parts. However, considering that if there is no buffering capacity during ejection, it will also lead to damage to the vehicle parts, the buffering mechanism in this application includes a telescopic sleeve 15 fixedly connected to the top of the linkage block 14. A spring 16 is fixedly connected to the inner wall of the telescopic sleeve 15. A buffer block 17 is fixedly connected to the top of the spring 16. A buffer rod 18 is fixedly connected to the top of the buffer block 17. The top of the buffer rod 18 extends through to the top of the telescopic sleeve 15 and is fixedly connected to the bottom of the ejector plate 5.

[0042] In this embodiment, considering that the lack of buffering capacity during ejection could also lead to damage to vehicle parts, a buffering mechanism is provided. When the ejector rod 6 comes into contact with the vehicle parts, the ejector plate 5 will move downward under the influence of pressure, which will simultaneously drive the buffer rod 18 and the buffer block 17 to move downward. The buffer block 17 will compress the spring 16, and the reaction force of the spring 16 will achieve the buffering effect, thus avoiding damage to vehicle parts during ejection.

[0043] The spring 16 has a limiting post 19 inside, and the bottom of the limiting post 19 is fixedly connected to the inner wall of the telescopic sleeve 15.

[0044] In this embodiment, by setting the limiting post 19, the spring 16 can be prevented from deforming when compressed, thus extending the service life of the spring 16.

[0045] Working principle: After the automotive parts are formed in the molding cavity 3, the starting motor 7 drives the missing gear 8 to rotate. When the toothed section of the missing gear 8 contacts the transmission gear 9, it will drive the transmission gear 9, transmission rod 10 and first bevel gear 11 to rotate around the first rotating shaft. Since the first bevel gear 11 and the second bevel gear 12 mesh, they will drive the second bevel gear 12 and threaded rod 13 to rotate around the second bearing 23. While the threaded rod 13 rotates, its external thread will squeeze the internal thread of the threaded hole 24, causing the linkage block 14 to move upward. The linkage block 14 will drive the telescopic sleeve 15, buffer block 17 and buffer rod 18 to move upward. At the same time, it will drive the ejector plate 5 and ejector rod 6 at the top of the buffer rod 18 to move upward. Multiple ejector rods 6 will evenly squeeze the automotive parts, thus achieving the effect of ejection and demolding. At the same time, every time the missing gear 8 rotates one revolution and contacts the transmission gear 9, the ejector rod 6 will rise a bit to eject the automotive parts, effectively avoiding damage to the automotive parts.

[0046] When the ejector rod 6 comes into contact with the vehicle parts, the ejector plate 5 will move downward under the influence of pressure, which will also drive the buffer rod 18 and the buffer block 17 to move downward. The buffer block 17 will squeeze the spring 16, and the reaction force of the spring 16 will achieve the buffering effect, thus avoiding damage to the vehicle parts during ejection.

[0047] It should be noted that the motor 7 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the motor 7 are clear to those skilled in the art, so they will not be described in detail here.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
