[0028] The present invention provides the following embodiments

[0029] Example 1

[0030] The embodiment of the present invention provides a system for laser cleaning molds, such as Figure 1-Figure 2 As shown, it includes a base 1, a leg 2 is provided at each of the top corners of the lower end of the base 1, a mounting platform 3 is rotatably provided at the middle part of the upper end of the base 1, and the mounting platform 3 is used to fix the mold to be cleaned, a driving platform 6 is fixedly provided on the rear side of the upper end of the base 1, and a sliding groove is provided at the front end of the driving platform 6, a threaded segment of a threaded rod 7 is rotatably provided in the sliding groove, and the threaded segment of the threaded rod 7 is threadedly connected to the mounting block 8, and a mounting block 8 is slidably provided in the sliding groove, and the mounting block 8 is connected to the laser cleaning mechanism, and the laser cleaning mechanism is arranged corresponding to the mold to be cleaned. A working chamber 16 is provided inside the base 1, and the cylindrical section of the threaded rod 7 passes through the lower end of the sliding groove and the rear side of the upper end of the base 1 to enter the working chamber 16, and a rotating shaft 24 is rotatably provided on the front side of the working chamber 16, and the rotating shaft 24 passes through the middle part of the upper end of the base 1 and is fixedly connected to the mounting platform 3, and an intermittent driving mechanism is connected between the rotating shaft 24 and the cylindrical section of the threaded rod 7. The setting of the intermittent driving mechanism makes the rotating shaft 24 and the threaded rod 7 rotate intermittently.

[0031] The beneficial effects of the above technical solution are:

[0032] After the mounting table 3 fixes the mold to be cleaned, the laser cleaning mechanism is extended into the mold to be cleaned to clean its inner wall. When the rotating shaft 1 24 rotates, it can drive the mounting table 3 to rotate. When the mounting table 3 rotates, it can drive the mold to be cleaned to rotate. When the threaded rod 7 rotates, it can drive the mounting block 8 to slide up and down along the sliding groove. The mounting block 8 drives the laser cleaning mechanism to move up and down. The setting of the intermittent driving mechanism makes the rotating shaft 1 24 and the threaded rod 7 rotate intermittently, so that when the rotating shaft 1 24 drives the mold to be cleaned in the mounting table 3 to rotate, the threaded rod 7 stops rotating. At this time, the mounting block 8 cannot move up and down, and the laser cleaning mechanism remains stationary. The laser cleaning mechanism cleans the inner wall of the mold to be cleaned corresponding to its current height. When the rotating shaft 24 stops rotating, the threaded rod 7 rotates. At this time, the mounting block 8 moves downward, driving the laser cleaning mechanism to move downward. The distance the laser cleaning mechanism moves downward each time is the same as the irradiation and cleaning length in the up and down directions, thereby ensuring that the laser cleaning mechanism can perform all-round cleaning of the inner wall of the mold to be cleaned, solving the technical problem that when the laser cleaner spirally irradiates the inner wall of the mold downward, there is an area that the laser cleaner cannot irradiate, making it difficult to clean the mold in all directions, thereby affecting the cleaning effect of the mold.

[0033] Example 2

[0034] On the basis of Example 1, Figure 1-Figure 2 As shown, the upper end of the mounting platform 3 is provided with a mounting slot 4, and the front, rear, left and right ends of the mounting slot 4 are each provided with a fixing block 5, and the fixing block 5 is fixedly connected to the electric telescopic rod 15, and the electric telescopic rod 15 is fixedly set in the mounting platform 3. The mounting slot 4 is used to place the mold to be cleaned;

[0035] The laser cleaning mechanism includes a connecting block 9, the rear part of which is fixedly connected to a fixed shaft 29, which is rotatably connected to a groove 28, and the fixed shaft 29 passes through the upper end of the groove 28 and is fixedly connected to a motor 11, which is fixedly arranged at the upper end of the mounting block 8, and the groove 28 is arranged at the front end of the mounting block 8, and the front end of the connecting block 9 is fixedly connected to a connecting block 2 10, and the lower end of the connecting block 2 10 is fixedly connected to the laser cleaner.

[0036] The beneficial effects of the above technical solution are:

[0037] The laser cleaner adopts the existing technology, which will not be described in detail in the present invention. When the mold to be cleaned is fixed in the mounting groove 4, the electric telescopic rod 15 is started, and the electric telescopic rod 15 drives the fixed block 15 to clamp and fix the mold to be cleaned, thereby achieving the purpose of fixing the mold to be cleaned in the mounting groove 4. When the motor 11 is working, it can drive the fixed shaft 29 to rotate, the fixed shaft 29 drives the connecting block 19 to rotate, the connecting block 19 drives the connecting block 2 10 to rotate, and the connecting block 2 10 drives the laser cleaner to rotate, thereby changing the position of the laser cleaner in the horizontal plane. The position of the laser cleaner can be adjusted according to the size of the inner wall of the mold to be cleaned, which is convenient for cleaning the inner wall of the mold to be cleaned. The setting of the connecting block 2 10 can enable the laser cleaner to extend into the mold to be cleaned, and the height of the connecting block 2 10 is greater than the depth of the inner wall of the mold to be cleaned.

[0038] Example 3

[0039] On the basis of Example 2, Figure 1-Figure 2 As shown, the intermittent drive mechanism includes a second motor 17, which is fixedly arranged at the lower end of the working chamber 16. The second motor 17 is fixedly connected to the drive shaft 18, and the drive shaft 18 is fixedly connected to the rotating disk 19. A guide rod 20 is eccentrically provided at the upper end of the rotating disk 19. The guide rod 20 corresponds to the guide groove 22. A matching wheel 21 is provided on the front side of the rotating disk 19, and a matching wheel 26 is provided on the rear side of the rotating disk 19. The matching wheels 21 and 26 are both evenly distributed with four guide grooves 22 around the circumference.

[0040] The mating wheel 1 21 is fixedly connected to the rotating shaft 2 23, and the rotating shaft 2 23 is rotatably set in the working chamber 16. The rotating shaft 2 23 is fixedly connected to the large gear, the large gear is engaged with the small gear 25, and the small gear 25 is fixedly connected to the rotating shaft 1 24. The mating wheel 2 26 is fixedly connected to the cylindrical section of the threaded rod 7.

[0041] The beneficial effects of the above technical solution are:

[0042] When the motor 2 17 is working, it drives the drive shaft 18 to rotate, and the drive shaft 18 drives the rotating disk 19 to rotate. When the rotating disk 19 rotates, it drives the guide rod 1 20 to rotate. The rotating disk 19, the guide rod 1 20, the guide groove 22, and the matching wheel 1 21 constitute a groove wheel mechanism. The rotating disk 19, the guide rod 1 20, the guide groove 22, and the matching wheel 2 26 also constitute a groove wheel mechanism. When the guide rod 1 20 is matched with the guide groove 22 on the matching wheel 1 21, it drives the matching wheel 1 21 to rotate. The matching wheel 1 21 drives the rotating shaft 2 23 to rotate. The rotating shaft 23 drives the large gear to rotate ninety degrees. The large gear drives the small gear 25 to rotate a number of full circles. The small gear 25 drives the rotating shaft 1 24 to rotate a number of full circles. After the guide rod 1 20 is disengaged from the guide groove 22 on the matching wheel 1 21 and is matched with the guide groove 22 on the matching wheel 2 26, the guide rod 1 20 drives the matching wheel 2 26 to rotate. , the mating wheel 26 drives the threaded rod 7 to rotate ninety degrees. When the threaded rod 7 rotates ninety degrees, it drives the mounting block 8 to move downward by the target distance. The distance the mounting block 8 moves downward is the same as the irradiation length of the laser cleaner in the up and down directions. After the mounting block 8 moves downward by the target distance, the guide rod 1 20 disengages from the guide groove 22 on the mating wheel 26, and the laser cleaner stops moving. After the guide rod 1 20 re-engages with the guide groove 22 on the mating wheel 1 21 and drives the rotating shaft 1 24 to rotate several circles, it engages with the guide groove 22 on the mating wheel 26 again and drives the threaded rod 7 to rotate, and the laser cleaner starts to move. With the rotation of the drive shaft 18, the purpose of intermittent rotation of the rotating shaft 1 24 and the threaded rod 7 is achieved. When the motor 2 17 works in reverse to cause the drive shaft 18 to rotate in the opposite direction, the threaded rod 7 can be rotated in the opposite direction, thereby causing the mounting block 8 to move upward and return to its original position.
