The movable plate will move along the inner wall of the cavity through the cooperation between the threaded rod and the movable plate, so that the movable plate can drive the return spring to move upward and press the movable frame. Due to the ductility of the bellows, the movable frame will rotate along the top of the mounting table when the return spring presses the movable frame. Then, the fan can output air flow to the blowing pipe and the bellows in turn and discharge from the movable frame, which facilitates the blowing of the debris on the top of the mounting table into the gap between the protective shell and the machine table, and then the debris can be collected in the collection bin.

DETAILED DESCRIPTION

[0028] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described with reference to the accompanying drawings.

[0029] Example 1 Reference Figure 1 and Figure 2 The first embodiment of the present application provides a laser processing device for mold manufacturing, which comprises a laser processing equipment 1, a processing table is arranged below the laser processing equipment 1, and a smoke collection device is arranged on the outer wall of the laser processing equipment 1.

The impurity removal unit 3 is arranged inside the processing table and extends to outside of the processing table, and the impurity removal unit 3 comprises a turnover assembly and a vibration assembly, the turnover assembly is used for overturning the mold after processing to clean the mold corners and crevices, and the vibration assembly is used for driving the overturned mold to vibrate to make the adhered debris on the mold surface fall off. The guide unit 4 is arranged outside the impurity removal unit 3, and the guide unit 4 comprises a negative suction assembly and a debris blowing assembly, when the turnover assembly overturns and cleans the mold after processing, the turnover assembly extrudes the debris blowing assembly to make the debris blowing assembly blow the debris on the mold surface, and at the same time, the turnover assembly drives the negative suction assembly to operate to cooperate with the negative suction assembly to suck and collect the debris.

[0030] In use, when the mold is manufactured and processed, the laser processing equipment 1 is used for processing, and under the cooperation of the smoke prevention unit 2, the impurity removal unit 3 and the guide unit 4, the generated smoke and cooled debris can be collected and protected to avoid the spread of part of the smoke and debris to the working environment.

[0031] Embodiment 2 Reference Figures 3-5 The second embodiment of the application is different from the above embodiment, and is further optimized on the basis of the above embodiment, and the specific embodiments are as follows: The smoke suction assembly comprises a moving mechanism 21, the bottom of the moving mechanism 21 is connected with an extension rod 22, the outer wall of the moving mechanism 21 is connected with a sliding column 23, a frame 24 is arranged outside the moving mechanism 21, a protection box 25 is slidably connected to the outer wall of the frame 24, a suction head 26 is communicated with the inner wall of the protection box 25, an extension sleeve 27 is connected to the side wall of the protection box 25, and the dismounting assembly comprises a sliding groove 29, the inner wall of the sliding groove 29 is connected with a first magnetic ring 210, the second magnetic ring 211 is slidably connected inside the sliding groove 29, the side wall of the second magnetic ring 211 is connected with a locking pin 212, the locking pin 212 is provided with a mounting frame 213 on the outside, the mounting frame 213 is connected with a check ring 214 on the inside, and the check ring 214 is provided with an adsorption filter plate 215 inside.

[0032] The outer wall of the frame 24 is sealed and slides inside the protective box 25, and the end of the suction head 26 is connected to the inside of the protective box 25. When the protective box 25 slides away from the frame 24, the frame 24 can draw air from the protective box 25 and the suction head 26 to collect and process the uncollected flue gas.

[0033] When in use, during mold manufacturing, the mold is clamped on the top surface of the processing table. At this time, the telescopic rod 22 is activated, which pulls the moving mechanism 21 downward. The sliding column 23 fixedly installed on the outer wall of the moving mechanism 21 slides in the inclined groove opened inside the protective box 25. Since the inside of the protective box 25 is slidably connected to the outer wall of the frame 24, under its restriction, the two protective boxes 25 move towards each other to protect the processing area. At this time, the two adsorption frames 28 attract each other to ensure that the processing area is in a closed state and to prevent the leakage of fumes from affecting the health of the operators. At this time, the moving mechanism 21 drives the laser processing equipment 1 to move in all directions and laser process the mold. The fumes during processing can be collected in time through the fume collection device matched with the laser processing equipment 1. When the mold has a large height difference, the telescopic rod 22 pushes the moving mechanism 21 upward, and the two protective boxes 25 move in opposite directions, pulling the telescopic sleeve 27. Under the restriction of the telescopic sleeve 27 and the suction frame 28, the two protective boxes 25 always keep the processing area closed, reserving a reasonable floating space for the moving mechanism 21 and the laser processing equipment 1 to perform up and down processing, ensuring processing flexibility while ensuring protection effect.During the flue gas collection process, some flue gas cannot be collected and diffused in time, requiring residual flue gas collection and treatment. After the mold is processed, the telescopic rod 22 pushes the moving mechanism 21 upward. Under the sliding restriction of the inclined groove opened on the inner side of the sliding column 23 and the protective box 25, the two protective boxes 25 move in opposite directions. Since the inside of the protective box 25 is sealed and slides against the outer wall of the frame 24, and the inside of the protective box 25 is connected to the inside of the telescopic sleeve 27, under its restriction, the frame 24 draws the gas inside the protective box 25, causing it to move away from the suction head. The gas inside the protective box 25 on one side is pushed into the telescopic sleeve 27. The suction head 26 collects some of the uncollected fumes from the corners inside the protective box 25. The suction head 26, in conjunction with the adsorption filter plate 215, filters and adsorbs particulate matter in the fumes. When the mold is processed again, the gas inside the protective box 25 is ejected. The gas treated by the adsorption filter plate 215 is clean gas. This structure allows for the removal of the processed mold while simultaneously collecting and treating residual fumes, preventing fumes from rushing towards the operators when the protective box 25 is opened. When the protective box 25 is opened, the moving mechanism 21 can drive the laser processing equipment 1 to move upward and reset, so that the operator can pick up and put down the mold. After the adsorption filter plate 215 has been used for a long time, it needs to be replaced. Press the locking pin 212, which drives the second magnetic ring 211 to slide into the slide groove 29. At this time, the adsorption filter plate 215 can be pulled out from the inside of the mounting frame 213 and the retaining ring 214 to replace it. Insert the new adsorption filter plate 215 into the inside of the mounting frame 213 and the retaining ring 214, release the locking pin 212, and then slide the second magnetic ring 211 into the slide groove 29. Under the magnetic repulsion constraint of a magnetic ring 210, the locking pin 212 can be pushed to the outside of the slide groove 29 to reset, thereby installing the adsorption filter plate 215. Since each adsorption filter plate 215 is an independently detachable structure, it ensures that the adsorption filter plate 215 can be fully used. This structure can automatically filter, adsorb and collect residual flue gas when the protective box 25 is opened, avoiding the flue gas rushing towards the operator at the moment the protective box 25 is opened, thus endangering the operator's safety. Moreover, this structure can collect flue gas in a closed manner, which can collect flue gas to the maximum extent compared with the traditional open collection.

[0034] Example 3 Reference Figure 6 and Figure 7 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as follows: The flipping assembly includes a frame 31, a motor 32 is connected to the inner side of the frame 31, a cross bar 33 is connected to the output end of the motor 32, a shelf 34 is slidably connected to the outer wall of the cross bar 33, and a clamping mechanism 35 is connected to the top surface of the shelf 34. The vibration assembly includes a retaining ring 36, a spring 37 is provided on the side of the retaining ring 36, a fixing block 38 is provided at the end of the spring 37 away from the retaining ring 36, and a convex ball 39 is connected to the side of the fixing block 38 away from the spring 37.

[0035] The retaining ring 36 is fitted inside the outer wall of the shelf 34, and the end of the spring 37 away from the retaining ring 36 is connected to the end of the shelf 34 near the motor 32. Under the restriction of the retaining ring 36, the sliding shelf 34 can compress the spring 37.

[0036] In use, when manufacturing and processing the mold, it is placed on the top surface of the placement plate 34. The cylinder in the clamping mechanism 35 pushes the clamping plate to clamp the mold. At this time, it can be laser-processed by the laser processing equipment 1. After processing is completed, the motor 32 is started, which drives the cross rod 33 to rotate. The cross rod 33 drives the placement plate 34 to rotate, flipping the clamped mold and cleaning the debris on the mold surface. When the placement plate 34 rotates, the fixing block 38 fixedly installed on its top surface drives the convex ball 39 to rotate as well. The convex ball 39 interacts with the processing... The sliding compression inside the table causes the shelf 34 to slide on the outer wall of the cross bar 33. In conjunction with the retaining ring 36 fixedly sleeved on the outer wall of the shelf 34, the spring 37 sleeved on the outer wall of the shelf 34 is compressed. When the convex ball 39 is no longer squeezed inside the processing table, the shelf 34 can be reset and pushed under the elastic action of the spring 37. The reciprocating motion causes the clamped mold to vibrate, which helps to clean the debris on its surface. This structure can invert the debris on the surface of the mold and coordinate with the vibration to clean it. The debris is collected by the negative suction bucket 44 to ensure the cleanliness of the top surface of the shelf 34.

[0037] Example 4 Reference Figure 8 and Figure 9 This is the fourth embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as follows: The negative suction assembly includes a transmission mechanism 41, inside which a rotating rod 42 is sleeved. A negative suction plate 43 is connected to the outer wall of the rotating rod 42. A negative suction bucket 44 is rotatably connected to the outer wall of the rotating rod 42. A cleaning plate 45 is slidably connected inside the negative suction bucket 44. The chip blowing assembly includes a spray frame 46. An air pipe 47 is connected to the outer wall of the spray frame 46. A third magnetic ring 48 is connected to the inner wall of the air pipe 47. A fourth magnetic ring 49 is provided on the side of the third magnetic ring 48. A sealing rod 410 is connected to the side wall of the fourth magnetic ring 49.

[0038] In use, when the motor 32 drives the cross rod 33 and the shelf 34 to rotate, the shelf 34 drives the convex ball 39 to rotate. The convex ball 39 slides and squeezes the end of the sealing rod 410, causing the sealing rod 410 to drive the fourth magnetic ring 49 to slide into the air pipe 47. Due to the sealing rod 410 and the air pipe 47 sliding in a sealed manner, the gas inside the air pipe 47 can be pushed and sprayed out towards the mold through the spray frame 46, blowing away the debris on the mold surface and assisting the cleaning unit 3 in cleaning the mold. The debris is collected by the negative suction bucket 44. When the cross rod 33 rotates, it passes through... The transmission mechanism 41 drives the rotating rod 42 to rotate, and the rotating rod 42 drives the negative suction plate 43 to rotate inside the negative suction bucket 44, which negatively absorbs and collects the debris blown down by the spray frame 46, preventing the debris from flying. When the sealing rod 410 is not squeezed, it can be reset and pushed under the magnetic repulsion of the fourth magnetic ring 49 and the third magnetic ring 48. After the debris is collected, the cleaning plate 45 is pulled to collect and unload the debris inside the negative suction bucket 44. This structure links the cleaning unit 3 and the guiding unit 4 to clean and collect the debris from laser processing, ensuring that the processing table is clean.

[0039] Example 5

[0040] Reference Figures 1-9 This is the fifth embodiment of the present invention. Unlike the embodiments described above, this embodiment provides a laser processing technology for mold manufacturing, applicable to any of the above embodiments, and includes the following steps: S1. During mold processing, the mold is clamped on the top surface of the processing table. The telescopic rod 22 is activated to pull the moving mechanism 21 downward. The sliding column 23 on its outer wall slides in the inclined groove inside the protective box 25. Because the protective box 25 is slidably connected to the outer wall of the frame 24, the two protective boxes 25 move in opposite directions to close the processing area. The adsorption frame 28 attracts each other to prevent smoke leakage. At this time, the moving mechanism 21 drives the laser processing equipment 1 to move the mold in all directions for processing, and the matching smoke collection device collects smoke in time. When the mold protrudes significantly, the telescopic rod 22 pushes the moving mechanism 21 upward. The two protective boxes 25 move in opposite directions to pull the telescopic sleeve 27. Under the restriction of the telescopic sleeve 27 and the adsorption frame 28, the mold remains closed, leaving room for floating during processing. After processing is completed, the telescopic rod 22 pushes the moving mechanism 21 upward again. The two protective boxes 25 move in opposite directions. Because the protective box 25... 5 is sealed and slides with the frame 24 and communicates with the telescopic sleeve 27. The frame 24 draws in the internal gas and collects the residual smoke in the corner through the suction head 26. It works with the adsorption filter plate 215 to filter particulate matter and sprays out clean gas during the next processing. When replacing the adsorption filter plate 215, press the locking pin 212 to drive the second magnetic ring 211 into the slide groove 29, and the filter plate can be pulled out. After the new adsorption filter plate 215 is installed, release the locking pin 212 and use the repulsive force between the second magnetic ring 211 and the first magnetic ring 210 to reset and fix it. The independent disassembly design ensures that the filter plate is fully utilized, and the overall closed structure has better smoke collection efficiency than the traditional open structure. S2. The mold is placed on the top surface of the storage plate 34 and fixed by the cylinder of the clamping mechanism 35. Then, it is processed by the laser processing equipment 1. After processing, the motor 32 is started to drive the cross rod 33 and the storage plate 34 to rotate, and the mold is flipped to pour out the debris. When the storage plate 34 rotates, the top surface fixing block 38 drives the convex ball 39 to squeeze the inside of the processing table, so that the storage plate 34 slides along the cross rod 33. The spring 37 is compressed by the retaining ring 36. After the convex ball 39 is released from the squeeze, the spring 37 pushes the storage plate 34 to reset. The reciprocating vibration assists in cleaning the debris. The debris is collected by the negative suction bucket 44 to ensure that the storage plate 34 is clean. When motor 32 drives cross rod 33 and placement plate 34 to rotate, convex ball 39 squeezes the end of sealing rod 410, causing it to drive fourth magnetic ring 49 to slide into air pipe 47. Because sealing rod 410 and air pipe 47 are sealed and sliding, gas is pushed through spray frame 46 to blow away mold debris, assisting cleaning unit 3 in cleaning. Debris is collected by negative suction bucket 44. At the same time, cross rod 33 drives rotating rod 42 and negative suction plate 43 to rotate in negative suction bucket 44 through transmission mechanism 41, negative suction collects blown debris to prevent it from flying. After sealing rod 410 is released from the squeeze, it is reset by the repulsive force between fourth magnetic ring 49 and third magnetic ring 48. After the debris is collected, pull cleaning plate 45 to unload material from negative suction bucket 44. This structure links cleaning unit 3 and guide unit 4 to ensure the cleanliness of processing table.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention. Furthermore, it should be noted that the components of the present invention are not limited to the overall application described above.
