Description
Technical Field
[0001] This utility model relates to the field of wheel hub decorative parts production technology, and in particular to a quick demolding device for wheel hub decorative parts. Background Technology
[0002] Wheel trim pieces, such as wheel caps and wheel covers, can add a unique visual effect to a vehicle and enhance its overall aesthetics. For example, wheel caps can prevent the screws inside the wheel from being corroded by the external environment, while their design adds a sense of style and recognizability to the vehicle. However, the production of wheel trim pieces requires injection molding using molds. After molding, the wheel trim pieces cool naturally, and the wheel is then demolded. Traditional demolding devices are not convenient for easily demolding wheel hubs with side molds. Furthermore, when the upper and lower molds separate, the molded wheel trim pieces can easily cause the wheel hub to be fixed at the lower mold. When the upper mold moves upward, the hot wheel hub will be pulled upward by heat adhesion, causing the wheel hub to deform and be damaged, thus reducing its performance. Utility Model Content

[0035] Working principle: In use, first start the drive motor 10 on the drive bracket 9. The drive motor 10 drives the two drive pulleys 12 to rotate. At the same time, the drive pulleys 12 are connected to their corresponding assembly pulleys 8 via belts, thereby driving the assembly fan blades 7 on the assembly pulleys 8 to rotate and blow air. Then, start the assembly cylinder 3, which drives the assembly push plate 4 to move upward. Then, the upper assembly mold 5 on the assembly push plate 4 separates from the lower assembly mold 23. At the same time, the rotating air blows through the two assembly ports on the assembly push plate 4, thereby blowing and cooling the material inside the lower assembly mold 23 to form a mold. This reduces the thermal adhesion between the material and the upper assembly mold 5 and allows the material to fall into the lower assembly mold 23.
[0036] Simultaneously, the connecting motor 19 is started, which drives the connecting rod 20 and the connecting wheel 21 to rotate. Because the connecting wheel 21 contacts the inner wall of the connecting groove and generates friction, the connecting wheel 21 moves in the connecting groove. Then, the connecting sleeve block 18 on the connecting motor 19 moves along the direction of the connecting support 17. Then, the connecting sleeve block 18 also drives the moving bracket 16 to move, which in turn drives the moving push rod 15 to move along the direction of the assembly processing table 1. Then, the moving push rod 15 also drives the moving slider 13 to move. Because the moving plate 14 is installed on the moving slider 13, the moving plate 14 also drives the connecting shell 22 and the assembly lower mold 23 to move.
[0037] Next, the movable motor 25 on the movable recess 24 is started, which drives the movable rod 26 and the movable support 27 to rotate. Then the movable support 27 also drives the assembly lower mold 23 to rotate, and the material inside the assembly lower mold 23 is unloaded and demolded after being rotated.
[0038] Simultaneously, the mounting motor 31 on the mounting bracket 30 is started, which drives the mounting gear 32 to rotate in both directions. Then, the mounting gear 32 also drives the mounting tooth plate 29 to move along one end of the mounting hollow plate 28. Subsequently, the mounting tooth plate 29 also drives the mounting push block to move, so that the mounting push block pushes the material for rapid demolding.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
