At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present utility model without substantially changing the technical content. Figure 1-3 As shown, the utility model provides a flash cutting device for automobile dust cover, which at least includes: a shell 1, a cutting drive assembly 4, a cutting execution plate 2 and a positioning bearing plate 5. Among them, the shell 1 is in a square shape as a whole, and a plurality of limit grooves 11 are provided on the inner side wall, and a first spring 12 is provided in each limit groove 11. The cutting execution plate 2 is located inside the shell 1, and a movable block 21 matching the limit groove 11 is provided on it to ensure that the cutting execution plate 2 can move up and down stably. Furthermore, the movable block 21 is located above the first spring 12, so that the cutting execution plate 2 can return to the initial position after being driven, and prepare for the next cutting. A plurality of cutting assemblies 3 are provided below the cutting execution plate 2, and the cutting assemblies 3 are used to cut rubber products. The cutting drive assembly 4 is located above the cutting execution plate 2, and the cutting drive assembly 4 is used to move the cutting execution plate 2 up and down. The positioning bearing plate 5 is located below the cutting execution plate 2, and a plurality of bearing holes corresponding to the cutting assemblies 3 are provided on it, and the bearing holes are used to place rubber products.

[0057] When in use, the rubber product to be cut is placed in the bearing hole of the positioning bearing plate 5; then, the cutting drive component 4 is started to drive the cutting execution plate 2 to move downward, so that the cutting component 3 contacts the rubber product and completes the cutting; after the cutting is completed, the cutting execution plate 2 returns to its initial position under the action of the first spring 12, ready for the next cutting.

[0058] like Figure 4-5As shown, in one embodiment, each cutting component 3 includes: a positioning cylinder 31, a telescopic cylinder 32, a cutter head 33 and a pressure rod 34. The positioning cylinder 31 is connected to the cutting execution plate 2, and the bottom of the positioning cylinder 31 is open. The telescopic cylinder 32 is nested in the positioning cylinder 31, and the bottom of the telescopic cylinder 32 is open. A second spring 35 is provided between the positioning cylinder 31 and the telescopic cylinder 32. A cutter head 33 is detachably provided below the telescopic cylinder 32, and the cutter head 33 matches the bearing hole. When in use, the downward movement of the cutting execution plate 2 will drive all the cutting components 3 to move synchronously. When the cutter head 33 contacts the rubber product on the positioning bearing plate 5, the telescopic cylinder 32 connected to the cutter head 33 will be compressed, thereby compressing the second spring 35. This design allows the cutter head 33 to have a certain buffer when contacting the rubber product, thereby avoiding breakage or damage due to direct impact.

[0059] Furthermore, a pressure rod 34 is provided inside the positioning cylinder 31, one end of the pressure rod 34 is connected to the cutting execution plate 2, a hole with the same diameter as the pressure rod 34 is provided at the top of the telescopic cylinder 32, and a limiting ring 341 is provided on the pressure rod 34, and the limiting ring 341 is located inside the telescopic cylinder 32. The telescopic cylinder 32 can be fixed inside the positioning cylinder 31 by the limiting ring 341. In this scheme, when the cutter head 33 contacts the rubber product and completes the cutting, the cutting execution plate 2 continues to move downward, driving the pressure rod 34 to continue to move downward. When the pressure rod 34 contacts the plastic product in the bearing hole, the plastic product will be pressed out of the bearing hole due to the continued downward pressure of the pressure rod 34, thereby completing the entire cutting and pushing action. In one embodiment, a finished product bin 14 is provided at the lower part of the housing 1, and a collection box 6 is provided in the finished product bin 14 for collecting the finished products pushed out of the bearing hole. A take-out port 15 matching the collection box 6 is provided on one side of the finished product bin 14.

The drive motor 43 is connected to a drive shaft 42, and the drive shaft 42 passes through the housing 1. The drive shaft 42 is located above the cutting execution plate 2. An eccentric wheel 41 is provided on the drive shaft 42, and the eccentric wheel 41 is provided on the drive shaft 42, so that when the drive shaft 42 rotates, the outer edge of the eccentric wheel 41 will produce up and down reciprocating motion. When the eccentric wheel 41 moves downward, it compresses the first spring 12, thereby storing energy in the spring. At the same time, this downward force will also compress the cutting execution plate 2 to move downward. When the eccentric wheel 41 moves upward, it releases the energy stored in the first spring 12, so that the spring returns to its original state, and then pushes the cutting execution plate 2 to move upward.

[0061] like Figure 7 As shown, in another embodiment, the device is manually controlled. Specifically, the cutting drive assembly 4 includes: an eccentric wheel 41, a drive shaft 42 and a crank 44. The crank 44 is located outside the housing 1, and one end of the crank 44 is connected to the drive shaft 42, which passes through the housing 1. The drive shaft 42 is located above the cutting execution plate 2, and an eccentric wheel 41 is provided on the drive shaft 42. In this way, the staff can realize the cutting function by turning the crank 44 once.

[0062] One side of the housing 1 of the device is provided with a placement opening 13 matching the positioning carrier plate 5, and the positioning carrier plate 5 can be placed in the housing 1 through the placement opening 13. At the same time, in order to ensure the accuracy and stability of cutting, the positioning carrier plate 5 and the opening of the housing 1 are matched with a card slot buckle, ensuring a close correspondence between the positioning carrier plate 5 and the cutting execution plate 2.

[0063] To ensure the flexibility of the device and to meet the cutting requirements of different rubber products, in one embodiment, the limit ring 341 is threadedly connected to the pressure rod 34, and the telescopic cylinder 32 is threadedly connected to the cutter head 33. According to the different specifications of the automobile dust cover, the cutter head 33 and the positioning bearing plate 5 that match it are replaced accordingly.

[0064] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
