Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning, in particular to a laser cleaning inlet and outlet tooling. Background Art

[0002] Tire molds are made of aluminum alloy, gray cast iron or steel, and are important tools used in the tire vulcanization process. During use, the molds are inevitably contaminated by the combined deposition of rubber, compounding agents and release agents used in the vulcanization process. Repeated use will cause some dead areas of pattern contamination. Therefore, the molds must be cleaned regularly to ensure the cleanliness of their surfaces in order to ensure the quality of the tire and the life of the molds. In view of this, the development of tire mold cleaning technology has attracted much attention in the industry.

[0003] Currently, tire molds can be cleaned by laser cleaning. When a short pulse of high-energy laser is irradiated to the surface of the material, the surface absorbs the laser energy and converts it into internal energy, causing the surface temperature to rise rapidly to above the vaporization temperature of the material, thereby allowing pollutants to separate from the material surface in the form of steam. Laser cleaning is a non-contact cleaning method that does not require physical contact with the mold surface, thus avoiding damage to the mold, extending the service life of the mold, having high environmental performance, and relatively low energy consumption.

[0004] For example, the Chinese utility model patent with patent number 202022022168.6 provides a dual-station tire mold cavity cleaning machine, which can also be used with a laser cleaning robot arm to reduce dust generation and effectively improve the efficiency of cleaning the mold. However, when using the existing dual-station tire mold cleaning device, it is not convenient to load and unload the mold outside the cleaning area, which makes the cleaning area susceptible to contamination and affects the cleaning effect. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model proposes a laser cleaning entry and exit tooling to solve the technical problem that the existing tire mold double-station cleaning device proposed in the above background technology is inconvenient to load and unload the mold outside the cleaning area when in use, which makes the cleaning area susceptible to contamination.

[0015] In a preferred embodiment, two groups of hydraulic telescopic rods are provided on the frame, and lifting plates are provided at the ends of the hydraulic telescopic rods. When the support frame moves out of the cleaning area, the lifting plates can be lifted and pass through the support frame.

[0016] In a preferred embodiment, two groups of control switches are provided on the frame, and the two groups of control switches are electrically connected to the two groups of hydraulic telescopic rods respectively, and the support frame can abut against the control switches when moving out of the cleaning area.

[0017] In a preferred embodiment, a buffer pad is provided on one side of the frame, and the buffer pad is made of a flexible material.

[0037] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0038] Example:

[0039] like Figure 1 , 2 As shown, the utility model provides a laser cleaning in-and-out tooling, including a frame 101, on which two groups of mounting plates 201 are slidably arranged, and a support frame 202 is arranged at the end of the mounting plate 201. A driving assembly connected to the two groups of mounting plates 201 is arranged on the frame 101, and the two groups of mounting plates 201 are driven by the driving assembly to slide in opposite directions alternately to move the support frame 202 into or out of the cleaning area. The driving assembly includes a first gear 204 rotatably arranged on the frame 101 along its axis, a driving motor 205 is fixedly arranged on the frame 101, and the output shaft of the driving motor 205 is connected to the first gear 204, and first racks 203 are arranged on both groups of mounting plates 201, and the two groups of first racks 203 are arranged opposite to each other, and the two groups of first racks 203 are meshed with the first gear 204.

[0040] The tooling is installed on a double-station laser cleaning machine for use, so that the two groups of support frames 202 correspond to two groups of cleaning areas respectively, and one group of support frames 202 is located in one group of cleaning areas, so as to laser clean the tire mold on the support frame 202. After cleaning, the driving motor 205 can be controlled to start, driving the first gear 204 to rotate back and forth. During the rotation process, the first gear 204 drives the two groups of mounting plates 201 to slide in opposite directions through the engagement with the two groups of first racks 203, so that the cleaned group of tire molds is moved out of the cleaning area, and the uncleaned group of tire molds is moved into the cleaning area, so that the tire mold can be replaced outside the cleaning area, avoiding pollution to the cleaning area when loading and unloading the tire mold. It also makes the loading and unloading of the mold and the cleaning of the support frame 202 more convenient.

[0041] like Figure 1 , 4As shown, in this embodiment, two groups of hydraulic telescopic rods 103 are provided on the frame 101, and lifting plates 104 are provided at the ends of the hydraulic telescopic rods 103. When the support frame 202 moves out of the cleaning area, the lifting plates 104 can be lifted and penetrate the support frame 202. Two groups of control switches 102 are provided on the frame 101, and the two groups of control switches 102 are electrically connected to the two groups of hydraulic telescopic rods 103 respectively, and the support frame 202 can abut against the control switches 102 when it moves out of the cleaning area.

[0042] When the frame 101 is moved out of the cleaning area, a set of hydraulic telescopic rods 103 corresponding to the abutment control of the control switch 102 can be extended, and the lifting plate 104 can be lifted to penetrate the support frame 202, so as to lift up the tire mold in the support frame 202, and facilitate the loading and unloading of the mold. A buffer pad 105 is provided on one side of the frame 101, and the buffer pad 105 is made of a flexible material. The buffer pad 105 buffers the movement of the support frame 202 to prevent the control switch 102 from being damaged due to excessive movement of the support frame 202.

[0043] like Figures 1 to 3 As shown, in this embodiment, a cleaning mechanism is provided on the frame 101, and the support frame 202 moved out of the cleaning area is cleaned by the cleaning mechanism. The cleaning mechanism includes a support rod 301 rotatably provided on the frame 101 along its axis, a cleaning nozzle 305 installed through a rocker arm 303 is provided on the support rod 301, a water supply pump 304 connected to the cleaning nozzle 305 is provided on the rocker arm 303, and the water supply pump 304 is connected to an external water source. A linkage assembly connected to the support rod 301 is provided on the first gear 204, and the linkage assembly drives the support rod 301 to rotate when the support frame 202 moves out of the cleaning area to move the cleaning nozzle 305 to the top of the support frame 202.

[0044] The linkage assembly includes a second gear 206 arranged on the first gear 204 and coaxially connected thereto, a second rack 306 is slidably arranged on the frame 101, the second rack 306 is meshed with the second gear 206, a driving column 307 is arranged on the second rack 306, a sliding frame 302 is arranged on the support rod 301, and the driving column 307 is slidably clamped in the sliding frame 302.

[0045] When the first gear 204 is driven to rotate back and forth by the driving motor 205, the first gear 204 drives the second gear 206 to rotate, thereby controlling the second rack 306 to slide back and forth on the frame 101. The second rack 306 drives the driving column 307 to move during the sliding process, and then the support rod 301 is controlled to slide back and forth along its axis through the cooperation between the driving column 307 and the sliding frame 302, so as to move the cleaning nozzle 305 alternately to the top of the two groups of support frames 202. After the mold is removed, the water supply pump 304 is used to supply water to the cleaning nozzle 305 to rinse the support frame 202 to avoid impurities adhering to the support frame 202 and affecting the subsequent mold cleaning.

[0046] Specific usage and beneficial effects of the utility model:

[0047] When in use, the tooling is installed on one side of the double-station laser cleaning machine, so that the two groups of support frames 202 are aligned with the two groups of cleaning areas, and the tire mold to be cleaned is placed in the support frame 202, one group of support frames 202 is located in one group of cleaning areas, and the other group of support frames 202 is located outside the other group of cleaning areas.
