Description

Technical Field

[0001] The utility model relates to the technical field of production of die-cast aluminum alloy shells of automobile multimedia central control systems, in particular to a tool for removing the skin of the die-cast aluminum alloy shells of automobile multimedia central control systems. Background Art

[0002] The automotive multimedia system mainly includes audio-visual entertainment system, human-computer exchange interaction system, GPS navigation system, etc. With the continuous improvement of people's requirements for riding comfort, the multimedia technology of automobiles is also developing rapidly. Due to the high appearance quality requirements of automotive multimedia boxes, the one-piece die-cast aluminum alloy shell is under development. Affected by the product structure, the product has local appearance defects. Most of the appearance defects can be improved through pouring design and process optimization. The difficulty is that the appearance cold insulation cannot be completely eradicated. This position is relatively special. It is located on the vertical surface on both sides of the installation opening of the data interface. The defect position of the mold flow analysis is exactly the same as the defect position of the actual production. Its end face is an important glue dispensing sealing surface. It is not allowed to open an exhaust channel on the end face. The improvement effect through pouring design and process optimization is not obvious. In order to solve the above problems, a 1.0mm "skin" is added at the opening as an exhaust channel. Through mold flow analysis, it can be seen that after adding the "skin", the defects are transferred to the added "skin", and the defects at the opening are significantly improved. Therefore, it is only necessary to remove the skin from the aluminum alloy shell after molding. Existing technologies for removing the septum mainly include: manual cleaning and grinding to remove the septum, trimming die to remove the septum, and machining to remove the septum.

[0003] Removing the partition by trimming die is a common method in the die-casting industry. The trimming die can remove the partition in the horizontal direction, but the partition of the product is a vertical surface and cannot be removed by the trimming die. Removing the partition by trimming die is not feasible; machining to remove the partition has obvious market competitive advantages in terms of cost because the aluminum alloy shell does not have subsequent machining. If a machining process is added to remove the "partition", the cost increase is very obvious, causing the price advantage of the project product to decline sharply. Therefore, machining to remove the partition is not feasible; manual cleaning and polishing to remove the partition is actually feasible, but manual removal of the partition has a long cycle and low efficiency, which cannot meet the production capacity requirements. Moreover, since the facade of the product is thin, manual removal of the partition is prone to deformation of the facade, and the quality of glue dispensing will decline or the glue will break, resulting in a decrease in the sealing effect of the multimedia box.

[0004] Therefore, the goal is to develop a tooling and technology to remove the "facade partition" that can ensure both product quality requirements and production capacity requirements. Utility Model Content

[0021] When in use, the punching pad 5 is used to support the product facade and ensure the stability of the product when removing the partition. The cylinder power system is the power source of the tooling, which consists of a punching cylinder 9, a cylinder bracket 8, a push-pull rod, a Havers connection, an oil inlet, and an oil return port. The punching cylinder 9 is installed on the cylinder bracket 8. The Havers connection connects the cylinder push-pull rod and the oblique pin together, thereby providing power for the oblique pin punching system. When punching the partition, oil is supplied to the oil inlet, and the push-pull rod moves forward to punch the knife 12 to cut off the partition; after the punching is completed, oil is supplied to the oil return port, and the push-pull rod moves backward to pull back the punching knife 12.

[0022] See also Figure 1 and Figure 3 Further, the travel control mechanism 3 includes a travel switch seat 31 and a connecting rod 32 arranged opposite to the travel switch seat 31, the top of the travel switch seat 31 is fixedly mounted with an advance limit switch 33 and a retreat limit switch 35 at the top of the travel switch seat 31, the advance limit switch 33 is fixedly mounted with an advance limit touch bead 34, the retreat limit switch 35 is fixedly mounted with a retreat limit touch bead 36, one side of the connecting rod 32 is fixedly mounted with an advance limit contact 38 and a retreat limit contact 37, the advance limit contact 38 is arranged opposite to the advance limit touch bead 34, the retreat limit touch bead 36 is arranged opposite to the retreat limit contact 37, and the connecting rod 32 is fixedly mounted on the punching slide 11;

[0023] When in use, the stroke control system is the safety guarantee of the tooling. The stroke switch is installed on the cylinder mechanism, and other components are installed on the bottom plate of the stroke switch. The connecting rod 32 connects the stroke rod with the push-pull rod of the cylinder, and the cylinder push-pull rod drives the stroke rod to move synchronously. When the cylinder is pushed forward into place, the advance limit contact 38 hits the advance limit bump bead 34 of the advance limit switch 33, and the cylinder stops moving forward to prevent the punch 12 from hitting the seat plate and damaging the blade; when the cylinder retreats backward to its position, the retreat limit contact 37 hits the retreat limit bump bead 36 of the retreat limit switch 35, and the cylinder stops moving backward to prevent the punch 12 from hitting the product and damaging the product.

[0024] Fixed brackets 2 are fixedly arranged on both sides of the bottom of the tooling base 1, a waste collection box 13 is placed in the middle of the bottom of the tooling base 1, and a blanking hole 14 is opened in the middle of the punching pad 5, and the blanking hole 14 is arranged opposite to the waste collection box 13.

[0025] See also Figure 1 and Figure 2 Further, the pressing mechanism 6 includes a pressing seat 61 and a pressing frame 62 rotatably arranged on the pressing seat 61, a threaded rod 63 is threadedly connected to the middle of the pressing frame 62, a capstan 64 is fixedly arranged at the top of the threaded rod 63, and a glue pressing head 65 is fixedly arranged at the bottom of the threaded rod 63;

[0026] When in use, after the die-cast aluminum alloy shell is placed stably, the clamping frame 62 is rotated to face the top of the die-cast aluminum alloy shell, and then the threaded rod 63 is rotated in turn to clamp the workpiece through the rubber pressing head 65 to prevent the product from shaking when the punching cylinder 9 is actuated.

[0027] When the embodiment of the present application is in use: the die-cast aluminum alloy shell to be processed is placed between multiple positioning blocks 7 and supported by the punching pad 5, and then the clamping mechanism 6 is rotated in sequence to lock and fix the die-cast aluminum alloy shell, and the power switch of the tool is clicked. The punching cylinder 9 pushes the punching slide 11 to slide on the guide rail 10, driving the punching knife 12 to move forward, and the vertical partition skin is cut off by the punching knife 12. The fallen partition skin will be discharged from the tool through the blanking hole 14 under the action of gravity, and enter the waste collection box 13 for unified collection; when the limit contact 38 touches the limit contact bead 34 of the limit switch 33, the punching cylinder 9 receives the signal, drives the punching slide 11 to reset, and the punching knife 12 retreats back to its original position and waits.

[0028] This technology provides a new technical solution for removing the "facade skin" of die-casting parts in the future, but it also has its limitations, that is, there needs to be enough space for movement on the inside of the product. Even so, the technology of this project has great market prospects.
