[0015] The technical solution of the present invention will be further described in detail and non - restrictively below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] Refer to Figures 1 to 8 , an embodiment of the present invention provides a trimming device for mold manufacturing, as Figure 1 shown. The trimming device for mold manufacturing includes a first upper die layer 1. A knife hanging block 2 is fixedly arranged below the first upper die layer 1. A first placement groove 21 is opened below the knife hanging block 2, and a deburring mechanism 3 is arranged in the first placement groove 21. A driving mechanism is externally connected above the first upper die layer 1. By driving the first upper die layer 1 to drive the knife hanging block 2 to punch downwards to complete the trimming operation, and the deburring mechanism 3 is used for deburring work after trimming.

[0017] As Figure 2 and Figure 3As shown in the figure, the deburring mechanism 3 includes a first spring 31 with one end fixedly connected to the upper side of the first placement groove 21. The other end of the first spring 31 is connected to a connecting plate layer 32. A sliding block 33 is slidably connected below the connecting plate layer 32. An opening hole is formed on one side of the sliding block 33, and a grinding assembly 34 is arranged in the opening hole. A sliding track 35 is formed in the first placement groove 21 on one side of the sliding block 33. A sliding ear adapted to the sliding track 35 is fixedly arranged at the corresponding position on the sliding block 33. The sliding block 33 slides along the sliding track 35 through the sliding ear. The elastic expansion and contraction of the first spring 31 can drive the connecting plate layer 32 to move up and down. At the same time, the sliding block 33 slidably connected to the connecting plate layer 32 slides up and down in the sliding track 35 through the sliding ear.

[0018] As Figures 5 to 7 shown in the figure, the grinding assembly 34 includes a first telescopic rod 341 with one end connected to one side inside the opening hole. The other end of the first telescopic rod 341 is connected to one side of a push plate 342. A fixed grinding block 343 is connected above the other side of the push plate 342, and a fixed connecting block 344 is connected below. A second spring 345 and an elastic connecting block 346 are fixedly connected above the fixed connecting block 344. A floating grinding block 347 is jointly connected above the second spring 345 and the elastic connecting block 346. The telescopic movement of the first telescopic rod 341 drives the fixed grinding block 343 and the floating grinding block 347 indirectly connected to its output end to be pushed out or retracted into the opening hole, that is, when deburring is required, the fixed grinding block 343 and the floating grinding block 347 are pushed out, and when deburring is not required, the fixed grinding block 343 and the floating grinding block 347 are retracted into the opening hole.

[0019] The fixed grinding block 343 and the floating grinding block 347 are designed with an inclined surface structure, and the height of the side close to the cutting edge is lower. When the first telescopic rod 341 extends, it drives the fixed grinding block 343 and the floating grinding block 347 to move towards the cutting edge. Due to the design of the inclined surface structure, the two grinding blocks can naturally clamp the cutting edge part, exerting a direct pressing and removing effect on the burrs.

[0020] As Figures 5 to 7As shown, inside the opening hole, a micro fan 348 is fixedly arranged below the first telescopic rod 341, and an elastic air bag 349 is arranged below the fixed connecting block 344. The micro fan 348 and the elastic air bag 349 are commonly connected by a connecting pipe 3481. A baffle 340 is fixedly arranged below one side of the opening of the opening hole. On the side of the elastic air bag 349 close to the baffle 340, an inclined air hole 3491 and a straight air hole 3492 are successively formed from bottom to top. A percussion ball 3493 is connected by an elastic cord to a section of the elastic air bag 349 where the straight air hole 3492 is formed.

[0021] When the first telescopic rod 341 extends to drive the fixed grinding block 343 and the floating grinding block 347 indirectly connected to its output end to be pushed out, the micro fan 348 starts to blow air into the elastic air bag 349 through the connecting pipe 3481, and the elastic air bag 349 expands and becomes larger. The internal air flow pressure of the expanded elastic air bag 349 increases, and the air flow begins to be discharged outward through the inclined air hole 3491 and the straight air hole 3492. The design of these air holes cleverly guides the flow direction and intensity of the air flow, so that the percussion ball 3493 located therein is blown up under the strong action of the air flow. Due to the connection of the elastic cord, the percussion ball 3493 is in a floating state. During the floating process, the percussion ball 3493 continuously collides with one side of the fixed connecting block 344, generating a percussion action.

[0022] The vibration energy generated by the percussion of the percussion ball 3493 is transmitted to the second spring 345 and the elastic connecting block 346 closely connected thereto through the fixed connecting block 344. The second spring 345 and the elastic connecting block 346, as the media for vibration transmission, have good elasticity and buffering performance. They further amplify the vibration energy and uniformly transmit it to the floating grinding block 347. Under the action of the vibration, the contact mode between the floating grinding block 347 and the edge of the mold changes subtly, changing from the original static contact to dynamic contact. This dynamic contact enables the floating grinding block 347 to more efficiently remove the burrs on the edge of the mold, especially those tiny and stubborn burrs that are difficult to remove by conventional grinding methods, thereby significantly improving the quality and efficiency of the deburring operation and ensuring that the surface quality of the mold reaches a higher standard.

[0023] Regarding the characteristic of less burrs on the cut edge, the fixed grinding block 343 adopts a rigid inclined plane structure and is directly pressed and removed by the stable pressure provided by the first telescopic rod 341. For the case of more lower burrs, the floating grinding block 347 is elastically connected through the second spring 345 and the elastic connecting block 346, and cooperates with the vibration system of the knocking ball 3493 driven by the micro fan 348 to form a dynamic grinding contact, which can more effectively remove stubborn lower burrs. This design combines the static pressing of the fixed grinding block 343 with the dynamic grinding of the floating grinding block 347, which not only ensures the deburring effect but also improves the working efficiency. At the same time, the inclined plane structure ensures that the two grinding blocks can closely fit the upper and lower surfaces of the cut edge at the same time, realizing precise deburring operation.

[0024] It should be noted that after the burr grinding is completed, when the first telescopic rod 341 retracts and drives the fixed grinding block 343 and the floating grinding block 347 indirectly connected to its output end to retract, when the side of the fixed connecting block 344 connected to the first telescopic rod 341 pushes the knocking ball 3493 to the inside of the baffle 340, the micro fan 348 is turned off, so that the elastic air bag 349 contracts and the knocking ball 3493 falls. After that, the first telescopic rod 341 continues to retract and drives the fixed grinding block 343 and the floating grinding block 347 indirectly connected to its output end to retract to the initial position.

[0025] In some preferred embodiments, such as Figure 2 and Figure 3 shown, a cutting edge tool head 4 is arranged below the deburring mechanism 3. An automatic hinge connecting piece 41 is commonly connected between the tool hanging block 2 and the cutting edge tool head 4, and the automatic hinge connecting piece 41 automatically controls the opening or closing of the cutting edge tool head 4 relative to the first placement groove 21.

[0026] Such as Figures 2 to 4 shown, a second placement groove 22 is further opened below the tool hanging block 2. A tool head auxiliary fixing mechanism 5 is arranged in the second placement groove 22. When the cutting edge tool head 4 is closed, a first magnetic block 42 is embedded below the second placement groove 22 on the cutting edge tool head 4, and the automatic hinge connecting piece 41 and the first magnetic block 42 are located at opposite ends of the cutting edge tool head 4.

[0027] Such as Figure 4As shown, the tool bit auxiliary fixing mechanism 5 includes a central shaft 51 inserted into the second placement groove 22. A rotating block 52 is sleeved on the central shaft 51. A second magnet 53 is fixedly arranged on one side of the rotating block 52, and a third magnet 54 is fixedly arranged on the other side of the rotating block 52. It should be noted that one end of the central shaft 51 can be connected to an external power source such as a motor to drive the flipping of the rotating block 52, the second magnet 53, and the third magnet 54.

[0028] The automatic hinge connector 41 is used to precisely control the relative opening and closing movement of the trimming tool bit 4 relative to the tool hanging block 2. During the actual working process, by skillfully applying the physical principle of "like poles repel, opposite poles attract" of the second magnet 53, the third magnet 54, and the first magnet 42, the flexible and stable opening and closing of the trimming tool bit 4 relative to the tool hanging block 2 are realized.

[0029] As Figure 2 and Figure 3 shown, when the trimming tool bit 4 opens relative to the tool hanging block 2 after trimming, the first spring 31 naturally extends to drive the connecting plate layer 32 to move downward. At the same time, the sliding block 33 slides obliquely downward along the sliding track 35, so that the fixed grinding block 343 and the floating grinding block 347 can be pushed out to perform the next step of deburring work. On the contrary, when the trimming tool bit 4 closes relative to the tool hanging block 2 after trimming, it will push the sliding block 33 to slide obliquely upward along the sliding track 35. Through the transmission of the connecting plate layer 32, the first spring 31 is compressed again until the trimming tool bit 4 completely closes relative to the tool hanging block 2 and returns to the initial state.

[0030] When it is necessary to open the trimming tool bit 4, under the combined influence of the initial action of the automatic hinge connector 41 and the magnetic force between the magnets, if the first magnet 42 and the second magnet 53 are opposite and have the same polarity at this time, a repulsive force is generated to assist in pushing the trimming tool bit 4 open; when it is necessary to close the trimming tool bit 4, the central shaft 51 drives the second magnet 53 and the third magnet 54 to rotate through the rotating block 52 , so that the first magnet 42 and the third magnet 54 are opposite and have opposite polarities, thereby generating an attractive force to firmly adsorb and close the trimming tool bit 4 on the tool hanging block 2, ensuring the stability and accuracy of the trimming operation.

[0031] In some preferred embodiments, as Figure 4 shown, the poles of the second magnet 53 and the third magnet 54 exposed on the outside are opposite.

[0032] In some preferred embodiments, as Figure 1As shown, a second upper die layer 6 is fixedly arranged below the first upper die layer 1, a third upper die layer 7 is arranged below the second upper die layer 6, a lower die layer 8 is arranged below the third upper die layer 7, and a blank 9 is placed between the third upper die layer 7 and the lower die layer 8.

[0033] The first upper die layer 1, the second upper die layer 6 and the third upper die layer 7 together constitute the upper die part, and the lower die layer 8 serves as the lower die part, and the upper and lower die parts cooperate with each other. Specifically, by externally connecting a driving mechanism above the first upper die layer 1, the driving mechanism can provide accurate and stable driving force to drive the entire upper die part to move downward and perform a die closing action with the lower die layer 8. During the die closing process, the hanging knife block 2 and the trimming cutter head 4 punch downward, so as to realize the trimming operation on the blank 9.

[0034] In some preferred embodiments, as Figure 1 shown, through holes adapted to the hanging knife block 2 are respectively formed in the second upper die layer 6, the third upper die layer 7 and the lower die layer 8 at positions corresponding to the hanging knife block 2 to ensure the smooth progress of the trimming work.

[0035] In some preferred embodiments, as Figure 1 shown, a guide post 61 is penetrated through the second upper die layer 6. The guide post 61 is a stud structure with a larger upper part and a smaller lower part. A larger section of the guide post 61 is hung on the second upper die layer 6. An auxiliary hole 11 adapted to the larger section is formed in the first upper die layer 1. A smaller section of the guide post 61 passes through the second upper die layer 6 downward and its lower end is fixedly connected to the third upper die layer 7. A third spring 62 is sleeved on a section of the guide post 61 between the second upper die layer 6 and the third upper die layer 7.

[0036] During die closing, the externally connected driving mechanism drives the second upper die layer 6, the third upper die layer 7 and the hanging knife block 2 to move downward through the first upper die layer 1 until the third upper die layer 7 presses the blank 9, drives the second upper die layer 6 and the hanging knife block 2 to move downward, the third spring 62 is compressed, and the hanging knife block 2 drives the trimming cutter head 4 to continue to move downward relative to the third upper die layer 7 to trim the blank 9.

[0037] In some preferred embodiments, as Figure 1 shown, a horizontal second telescopic rod 83 is fixedly arranged in the lower die layer 8. The output end of the second telescopic rod 83 is fixedly connected with an inner slider 82. An electric suction cup 81 is fixedly arranged above the inner slider 82. The upper surface of the electric suction cup 81 is attached to the lower surface of the blank 9.

[0038] The electric suction cup 81 has an electric control function and can firmly adsorb or release the sheet 9 according to actual needs. After the trimming operation is completed, the external driving mechanism drives the upper die part to separate from the sheet 9, and the electric suction cup 81 quickly starts the adsorption function to firmly suck the sheet 9 to ensure its stability during subsequent operations. Subsequently, the second telescopic rod 83 starts to extend. Through the transmission of the inner slider 82, the lower die layer 8 is provided with a chute adapted to the inner slider 82 and the electric suction cup 81, driving the electric suction cup 81 and the sheet 9 adsorbed thereon to move along the chute in the direction of the tool hanging block 2 by an appropriate distance.

[0039] When the sheet 9 moves to a suitable position, the trimming cutter head 4 opens relative to the tool hanging block 2, and at the same time the sliding block 33 slides out to make room for the grinding operation. Then, the external driving mechanism drives the upper die to descend to a suitable position again, so that the horizontal position of the sheet 9 is accurately located between the fixed grinding block 343 and the floating grinding block 347. The first telescopic rod 341 starts to push out. Under the push of the first telescopic rod 341, the fixed grinding block 343 and the floating grinding block 347 perform a comprehensive and detailed grinding operation on the burrs at the trimmed edge of the sheet 9.

[0040] In some preferred embodiments, as Figure 8 shown, the connecting plate layer 32 includes a first connecting plate 321 connected to the first spring 31. A second connecting plate 322 is fixedly arranged below the first connecting plate 321. A connecting slider 323 is arranged between the first connecting plate 321 and the second connecting plate 322. The connecting slider 323 is T-shaped, and the second connecting plate 322 is provided with a slide rail adapted to the connecting slider 323, and the connecting slider 323 is slidably matched with the slide rail.

[0041] In the above embodiment, the first upper die layer 1 drives the entire upper die part to move downward under the action of the external driving mechanism to perform a die closing operation with the lower die layer 8. During the die closing process, the tool hanging block 2 and the trimming cutter head 4 perform precise trimming on the sheet 9. The specific working process can be divided into the following key steps: Trimming stage: The external driving mechanism drives the second upper die layer 6, the third upper die layer 7 and the tool hanging block 2 to move downward through the first upper die layer 1 until the third upper die layer 7 presses the sheet 9, driving the second upper die layer 6 and the tool hanging block 2 to move downward. The third spring 62 is compressed, so that the tool hanging block 2 drives the trimming cutter head 4 to continue to move downward to complete trimming. At this time, the automatic hinge connector 41 remains in a closed state, and the first magnet 42 and the third magnet 54 assist in ensuring trimming stability through magnetic attraction.

[0042] Deburring stage: The external driving mechanism drives the upper die part to separate from the sheet 9. The electric suction cup 81 quickly activates its adsorption function to tightly suck the sheet 9. The second telescopic rod 83 starts to extend. Through the transmission of the inner slider 82, it drives the electric suction cup 81 and the sheet 9 adsorbed thereon to move an appropriate distance in the direction of the tool hanging block 2. The trimming cutter head 4 opens relative to the tool hanging block 2. At the same time, the sliding block 33 slides out. Then, the external driving mechanism drives the upper die to descend to an appropriate position again, so that the horizontal position of the sheet 9 is accurately located between the fixed grinding block 343 and the floating grinding block 347.

[0043] When the sheet 9 moves to the grinding station, the first telescopic rod 341 is pushed out to make the fixed grinding block 343 and the floating grinding block 347 push out to directly suppress and remove the burrs. After the micro fan 348 is started, the air flow forms a composite air flow through the inclined air holes 3491 and the straight air holes 3492, driving the knocking ball 3493 to generate multi-directional vibration. The vibration energy is transmitted to the second spring 345 and the elastic connecting block 346 through the fixed connecting block 344, causing the floating grinding block 347 to generate high-frequency vibration, realizing dynamic grinding and significantly improving the deburring efficiency.
