Description

Technical Field

[0001] This utility model relates to the field of automotive mold processing technology, and in particular to a demolding device for automotive die casting molds. Background Technology

[0002] Due to their complex structure, automotive parts require high precision and performance in their production. They are typically manufactured using die-casting molds. Die-casting can produce high-quality parts that meet the requirements, ensuring good strength and rigidity while reducing weight.

[0003] In automobiles, the wheel hubs of tires are manufactured using die-casting molds, which can improve the overall strength and safety of the vehicle body. Molten aluminum is injected into the mold cavity at high pressure and then cooled and solidified under pressure to obtain the desired casting.

[0004] The tire wheel hub is formed by pressing upper and lower molds together to create a cavity. Aluminum is then pressed into the cavity and formed into a hub under low pressure. The completed hub is moved upwards by the upper mold and then moved to the bottom of the hub by a sliding plate for collection. However, the completed hub cannot detach from the sliding plate on its own; it usually requires hammering to detach the hub from the upper mold, which is time-consuming, inefficient, and can damage and deform the newly formed hub. Therefore, a die-casting mold release device for automobiles is proposed to solve the above problems. Utility Model Content

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.

[0035] Reference Figures 1-5This utility model provides an embodiment of a die-casting mold release device for automobiles, including an upper mold 4 and a lower mold 29. The upper mold 4 and the lower mold 29 are pressed together to die-cast internal molten aluminum to form a wheel hub. A base 6 is fixedly connected to the bottom of the lower mold 29. Molten aluminum enters the lower mold 29 from the bottom of the base 6. This is prior art and not an improvement of this application, so it will not be described in detail here. A fixing block 21 is fixedly connected to the side of the base 6. A moving component is installed on the top of the fixing block 21. A sliding plate 15 is installed on the outside of the moving component. A lifting component is installed inside the sliding plate 15. The lifting component includes a slider 3 24, which is slidably connected to the inside of the sliding plate 15. A screw 25 is threadedly connected inside the slider 3 24. When the screw 25 rotates, the rotating screw 25 drives the slider 3 24 to move up and down. A worm gear 26 is fixedly connected to the outside of the screw 25. The rotation of the worm gear 26 drives the internally fixed screw 25 to move up and down. 5. The slide plate 15 is rotated. A motor 28 is fixedly connected inside the slide plate 15. A worm gear 27 is fixedly connected to the output end of the motor 28. When the motor 28 is started, it drives the worm gear 27 to rotate. The worm gear 27 meshes with the worm wheel 26. The rotating worm gear 27 drives the meshing worm wheel 26 to rotate. The rotating worm wheel 26 drives the internal screw 25 to rotate. The rotating screw 25 drives the slider 3 24 to move up and down. A clamping bracket 16 is fixedly connected to the top of the slide plate 15. The clamping bracket 16 stabilizes the internal structure. A bracket 17 is fixedly connected to the top of the clamping bracket 16. A fixed shaft 18 is rotatably connected inside the bracket 17. A slider 2 19 is fixedly connected to the end of the fixed shaft 18. A gripper 20 is slidably connected inside the slider 2 19. A fixed shaft 22 is fixedly connected to the end of the gripper 20. A bracket 23 is slidably connected to the outside of the fixed shaft 22. The bottom of the bracket 23 is fixedly connected to the top of the slider 3 24. When slider 3 24 moves downward, it drives bracket 2 23 to move downward. The moving bracket 2 23 drives the gripper 20 to rotate. The rotating gripper 20 slides inside slider 2 19, and at the same time drives slider 2 19 to rotate outside the fixed shaft 1 18. The four rotating grippers 20 retract inward to clamp the die-cast hub, so that the hub is separated from the upper mold 4, realizing the demolding of the die-cast hub. The other end of the gripper 20 is equipped with a soft block 21. When the gripper 20 clamps the hub, the soft block 21 protects the newly formed hub and prevents the hub from being scratched and deformed.

[0036] Reference Figure 1 , Figure 2 and Figure 6The moving component includes a screw 13, which is rotatably connected to the inner side of a fixed block 11. A motor 12 is fixedly connected to the outer side of the fixed block 11. The screw 13 is fixedly connected to the output end of the motor 12. When the motor 12 is started, it drives the screw 13 to rotate. A slider 14 is threadedly connected to the outer side of the screw 13. The rotating screw 13 drives the slider 14 to move back and forth. The outer side of the slider 14 is fixedly connected to the outer side of the slide plate 15. The rotating screw 13 driven by the motor 12 drives the slider 14 to move. The moving slider 14 drives the slide plate 15 to move, thereby moving the clamping structure fixed on the top of the slide plate 15 and realizing the demolding of the die-cast wheel hub.

[0037] Reference Figures 1-2 An electric push rod 7 is fixedly connected inside the base 6. An extrusion block 8 is fixedly connected to the end of the electric push rod 7. Activating the electric push rod 7 pushes the extrusion block 8. Fixed blocks 9 are slidably connected to both sides of the extrusion block 8. The extrusion block 8 moves inward along the fixed blocks 9 to seal the lower mold 29. When the upper mold 4 moves downward and presses against the lower mold 29, molten aluminum enters the gap between the lower mold 29 and the upper mold 4 from the bottom of the base 6, forming a wheel hub through die casting. An air pipe 10 is installed on the top of the fixed block 9, and the air pipe 10 is connected to an external air source. This is existing technology and not an improvement in this application, so it will not be elaborated further here. When the die-cast wheel hub is completed, due to the high temperature of the molten aluminum... As the wheel hub is lifted by the upper mold 4, it undergoes slight deformation. The air pipe 10 cools the wheel hub with air, enabling it to form quickly and reducing deformation of the wheel hub when clamped by the subsequent clamping components. A support rod 5 is fixedly connected inside the base 6, and a top plate 1 is fixedly connected to the top of the support rod 5. The support rod 5 is connected between the top plate 1 and the base 6, making the wheel hub die-casting mold structure more stable. An electric push rod 2 is fixedly connected to the bottom of the top plate 1, and a fixed plate 3 is fixedly connected to the bottom of the electric push rod 2. The upper mold 4 is fixedly connected to the bottom of the fixed plate 3. When the electric push rod 2 is activated, it drives the fixed plate 3 to move down, causing the upper mold 4 to move down and press against the lower mold 29, thus completing the wheel hub die-casting.

[0038] Working principle: First, the electric push rod 2 is activated to drive the fixed plate 3 to move down, which in turn moves the upper mold 4 down. At the same time, the electric push rod 7 is activated to push the extrusion block 8. The extrusion block 8 moves inward along the fixed block 9 to close the lower mold 29. When the upper mold 4 moves down and the lower mold 29 is pressed together, the aluminum liquid enters the gap between the lower mold 29 and the upper mold 4 from the bottom of the base 6, and the wheel hub is formed by die casting. The die-cast wheel hub is lifted with the upper mold 4 and cooled by the air pipe 10, so that the wheel hub is formed quickly.

[0039] Then, start motor 12 to drive screw 13 to rotate. The rotating screw 13 drives slider 14 to move back and forth. The moving slider 14 drives slide plate 15 to move, moving the clamping structure fixed on the top of slide plate 15 to the bottom of upper mold 4. Start motor 28 to drive worm 27 to rotate. The rotating worm 27 drives the meshing worm wheel 26 to rotate. The rotating worm wheel 26 drives the internal screw 25 to rotate. The rotating screw 25 drives slider 3 24 to move downward, driving bracket 2 23 to move downward. The moving bracket 2 23 drives the gripper 20 to rotate. The rotating gripper 20 slides inside slider 2 19, and at the same time drives slider 2 19 to rotate outside fixed shaft 18. The four rotating grippers 20 retract inward to clamp the die-cast hub. Start electric push rod 2 to move upper mold 4 further upward, so that the hub is separated from upper mold 4, realizing the demolding of die-cast hub.
