[0002] Aluminum alloy die casting molds are specialized tooling for mass production of aluminum alloy parts. Their core is a metal structure with a cavity that matches the shape of the target part. During operation, molten aluminum alloy is rapidly pressed into the cavity under high pressure.

The residual impurities can interfere with the accuracy of mold closing, causing dimensional deviations in the molded aluminum alloy parts, and ultimately adversely affecting the product qualification rate.
[0004] Therefore, a die-casting mold for aluminum alloy parts is proposed to address the above problems. Utility Model Content

[0026] Specific implementation examples are given below.
[0027] Please see Figure 1 - Figure 4This utility model provides a die-casting mold for aluminum alloy parts, including a base 1. A guide rod 4 is fixedly connected to the upper surface of the base 1. A top plate 5 is fixedly connected to the top end of the guide rod 4. An electric push rod 8 is fixedly connected to the upper surface of the top plate 5.

A rack 13 is meshed with the tooth end of the gear 12. The outer wall of the rack 13 is slidably connected to the inner wall of the rectangular groove 2. A dustproof component is provided on the outer wall of the rack 13. The dustproof component includes a connecting plate 15. The outer wall of the connecting plate 15 is fixedly connected to the outer wall of the rack 13. A dust cover 14 is fixedly connected to the outer wall of the connecting plate 15. The lower surface of the dust cover 14 is slidably connected to the upper surface of the base 1. The guide rod 4 is used to provide guidance and support for the sliding of the moving plate 6, ensuring that the moving plate 6 moves smoothly in the vertical direction. The top plate 5 fixedly connected to the top of the guide rod 4 is used to install and fix the electric push rod 8. The mold mounting seat 9 fixedly connected to the upper surface of the base 1 is used to install and fix the lower mold core 10. The rectangular groove 2 opened on the outer wall of the base 1 is used to install the motor 11. The gear 12 fixedly connected to the output end of the motor 11 is used to mesh with the rack 13, converting the rotational motion of the motor 11 into the linear motion of the rack 13. The rack 13, which is meshed with the teeth of the gear 12, is used to slide along the rectangular groove 3 under the drive of the gear 12, thereby driving the dustproof component to move. The rectangular groove 3 slidably connected to the outer wall of the rack 13 is used to limit the rack 13. The dust cover 14 fixedly connected to the outer wall of the connecting plate 15 is used to move above the lower mold core 10 to form a cover to block dust when not in use.
[0028] Furthermore, such as Figure 1 , Figure 3 As shown, a limiting frame 16 is fixedly connected to the upper surface of the base 1, and a limiting post 17 is fixedly connected to the outer wall of the dust cover 14. The outer wall of the limiting post 17 is slidably connected to the inner wall of the limiting frame 16. The slidable connection of the outer wall of the limiting post 17 to the inner wall of the limiting frame 16 can limit the movement trajectory of the dust cover 14.
[0029] Furthermore, such as Figure 4 and Figure 5As shown, a vertical plate 18 is fixedly connected to the upper surface of the dust cover 14, and a threaded rod 19 is threadedly connected to the inside of the vertical plate 18; a handwheel 23 is fixedly connected to one end of the threaded rod 19, and a limiting piece 24 is fixedly connected to the other end of the threaded rod 19; a cylinder 20 is rotatably connected to the outer wall of the limiting piece 24, and a clamping block 21 is fixedly connected to the outer end of the cylinder 20; a guide post 22 is fixedly connected to the outer wall of the clamping block 21, and the outer wall of the guide post 22 is slidably connected to the inside of the vertical plate 18; the handwheel 23 is used to facilitate the operator to apply rotational force, and the threaded rod 19 is threadedly connected to the upper surface of the dust cover 14, and the upper surface of the dust cover 14 is fixedly connected to the upper surface of the dust cover 14, and the lower surface of the dust cover 14 is threadedly connected to the upper surface of the dust cover 14, and the upper ... The limiting piece 24 fixedly connected to the other end of the threaded rod 19 is used to prevent the cylinder 20 from rotating synchronously when the threaded rod 19 rotates. The cylinder 20 rotatably connected to the outer wall of the limiting piece 24 is used to connect the clamping block 21, which converts the axial movement of the threaded rod 19 into a thrust on the clamping block 21. The clamping block 21 is used to directly contact the workpiece to be stamped, and the workpiece is clamped and limited by moving inward. The guide post 22 is used to guide and limit the movement of the clamping block 21, prevent the clamping block 21 from deviating during the movement, and ensure the stability of the clamping.
[0030] Working principle: When in use, the motor 11 is started, which causes the gear 12 to rotate. During the rotation of the gear 12, the rack 13 moves outward. The outward movement of the rack 13 drives the connecting plate 15 to move outward, which in turn causes the connecting plate 15 to drive the dust cover 14 to move outward. The outward movement of the connecting plate 15 prevents the dust cover 14 from blocking the downward movement of the moving plate 6. The workpiece to be stamped is placed above the dust cover 14 for continuous conveying. Then, the electric push rod 8 is started, which causes its output end to push the moving plate 6 to slide vertically along the guide rod 4. This causes the upper stamping die 7 on the lower surface of the moving plate 6 to move down synchronously, cooperating with the lower die core 10 on the die mounting base 9 to realize the die casting of aluminum alloy parts.
[0031] When not in use, starting the motor 11 causes it to reverse. The motor 11 starts and causes its output end to rotate, which in turn drives the gear 12 to rotate. During the rotation of the gear 12, the rack 13 that is meshed with it will move and move inward. During this process, the limiting post 17 fixedly connected to the outer wall of the dust cover 14 will slide in the inner wall of the limiting frame 16 fixedly connected to the upper surface of the base 1. By moving the dust cover 14 inward, it moves to the top of the lower mold core 10, which can shield the lower mold core 10. This achieves the effect of preventing dust from falling into the interior of the lower mold core 10 when not in use. It can effectively block impurities from falling into the lower mold core 10, avoid impurities from adhering and causing part size deviations due to impurities hindering the mold closing accuracy during subsequent die casting production, and ensure product qualification rate. When the mold is used again, there is no need to spend extra time cleaning the dust of the lower mold core 10. It can directly enter the production preparation stage, saving time and improving production efficiency.
[0032] Before stamping, the handwheel 23 is rotated. During the rotation of the handwheel 23, the threaded rod 19 is rotated. During the rotation of the threaded rod 19, the limiting plate 24 is rotated inside the cylinder 20. During the rotation of the threaded rod 19, due to the threaded connection between the threaded rod 19 and the vertical plate 18, the threaded rod 19 moves during the rotation and drives the clamping block 21 to move inward through the cylinder 20 to limit the workpiece to be stamped. This can firmly fix the workpiece to be stamped, prevent displacement during stamping, ensure stamping accuracy, reduce part size deviation and defective products, and make the stamping process more stable, reducing the risk of stamping failure caused by workpiece shaking.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
