With reference to fig. 3 to 5, an automatic mold cleaning device according to a preferred embodiment of the present invention is used for cleaning a mold 100, wherein the automatic mold cleaning device includes a device body 1, a rotation support member, and a cleaning member.

The rotary support assembly includes a rotary device 20. The rotating means 20 comprise a plurality of rotating rollers 21 uniformly distributed along the radial direction of the same circumference. A plurality of the rotating rollers 21 are each rotatably provided to the apparatus main body 1 to form an annular rotation driving structure 22. The diameter of the roller body of the rotating roller 21 is gradually and uniformly reduced from the outer ring to the inner ring of the annular rotation driving structure 22, and the top surfaces of the plurality of rotating rollers 21 are located on the same plane, so as to jointly bear the mold 100, and drive the mold 100 to rotate when the plurality of rotating rollers 21 synchronously rotate.

Obviously, at least three rotating rollers 21 are required to be provided according to the diameter of the mold 100, the weight of the mold 100 and other factors, and the size of the required supporting force and the size of the driving force for rotation are considered, however, the number of the rotating rollers 21 may be four, six or more, and the specific number thereof is not limited in detail here. In addition, the plurality of rotating rollers 21 are uniformly distributed in the circumferential direction of the mold 100, so that uniform supporting force and rotational force can be provided, and the mold 100 can be prevented from being deviated. In addition, the top surfaces of the plurality of rotating rollers 21 are located on the same plane, and preferably on the same horizontal plane, so as to support the mold 100 well on the horizontal plane.

Since the annular rotation driving structure 22 has different rotation speeds at different points in the radial direction of the circumference when rotating, the rotary roller 21 is provided as a circular table having an isosceles trapezoid cross section (i.e., the diameter of the roller body gradually decreases from the outer ring to the inner ring of the annular rotation driving structure 22), and the circular table is inclined in the lateral direction, that is, the top surfaces of the roller bodies of the rotary roller 21 are located on the same horizontal plane. When the mold 100 rotates, the rotation speeds of the different positions of the roller body of the rotating roller 21 are different, so that the problem of different rotation speeds of different points is solved well, and the annular rotation driving structure 22 can provide uniform driving force for the rotation of the mold 100.

It is worth mentioning that the shape, structure, etc. of the mold 100 may be inconvenient to directly place on the ring-shaped rotation driving structure 22, and in addition, the mold 100 or the rotating roller 21 may be damaged by friction during the continuous contact between the mold 100 and the rotating roller 21. Therefore, the rotation support assembly further includes an annular rotation platform 30, and the rotation platform 30 is disposed between the annular rotation driving structure 22 and the mold 100 to transmit rotation driving force.

The cleaning assembly includes a washing device 40. The cleaning device 40 comprises a cleaning element 41, wherein the cleaning element 41 is preferably a laser cleaning head to remove contaminants or impurities inside the mold 100 by laser cleaning techniques. The cleaning member 41 is provided to the apparatus body 1 in such a manner as to be able to clean the mold 100 when the mold 100 is rotated by the plurality of rotating rollers 21, wherein it is preferable that the cleaning member 41 is movable on the apparatus body 1. Wherein the movable movement comprises rotation movement, vertical movement and transverse movement, so as to provide different laser focal lengths at different angles and clean the die 100 at different positions, thereby achieving the purpose of thorough cleaning and effectively improving the cleaning quality.

It is worth mentioning that, to facilitate the cleaning of the interior of the mould 100, the cleaning assembly is arranged at the centre of the circumference, so as to facilitate the adjustment of the preset cleaning position of the cleaning element 41 on the cleaning assembly.

Specifically, because the mold 100 has a plurality of lines and a heavy inner opening, when performing automatic cleaning, the cleaning assembly needs to be disposed below the opening of the mold 100, and the high-power motor needs to be disposed below the opening of the mold 100, and the cleaning assembly and the motor driving shaft will interfere with each other in the installation space, which cannot be realized. In this application mould self-cleaning equipment, at first will treat that clear mould back-off is in rotary platform 30's top surface, then adjust wash component 41's position, laser focus and washing angle, make and wash the laser and pass at the center cyclic annular rotation drive structure 22 with can just be to waiting to clean the position behind the rotary platform 30, rotate rotatory roller 21 at last, make cyclic annular rotation drive structure 22 is rotatory, and pass through rotary platform 30 drives mould 100 rotates together, carries out laser cleaning. Since the distance and relative inclination angle between the cleaned position of the mold 100 and the laser cleaning head are not constant, after one of the positions is cleaned, the position of the cleaning element 41, the laser focal length and/or the cleaning angle are adjusted again, the next position is cleaned continuously, and so on until all the positions to be cleaned of the mold 100 are cleaned. Full automation operation, clean efficient, can effectively improve production efficiency to practice thrift the cost of labor. Since the cleaning element 41 can be moved (including rotating, moving laterally and moving vertically), each dead angle inside the mold 100 can be effectively cleaned during the cleaning process, and the cleaning quality is effectively improved.

With reference to fig. 6 in the specification, it is worth mentioning that, for a relatively light mold, in order to reduce the cost of the apparatus, the rotating roller 21 includes at least one driving roller 211 and at least two driven rollers, where the driven rollers cooperate with the driving roller 211 to be driven by the driving roller 211 to rotate. Obviously, since the rotating rollers 21 are uniformly distributed along the radial direction of the circumference, when there is one driving roller 211 and two driven rollers, three rotating rollers 21 are distributed in an equilateral triangle to provide uniform supporting force to the mold 100 and provide rotating power through the driving roller 211; when the number of the driving rollers 211 is two or more, the number of the driven rollers may be two or three or more. It should be noted that, regardless of the number of the driving rollers 211 and the driven rollers, a plurality of the rotating rollers 21 are uniformly distributed in the radial direction of the circumference, thereby providing uniform supporting force and rotational driving force. In addition, the specific embodiment of the driven roller being driven by the driving roller 211 to rotate is not limited, and for example, the driven roller can be driven by a synchronous belt set simultaneously wound around the rotating ends of the driving roller 211 and the driven roller. The rotating device further includes a first drive mechanism 23 that is provided to the apparatus main body 1 and drives the drive roller 211 to rotate. The mold 100 is supported by the driving roller 211 and the driven roller to provide a uniform supporting force, and the driving roller 211 provides a rotational power to rotate the mold 100. Since the greater the number of the drive rollers 211, the greater the number of the first driving mechanisms 23, it can be understood by those skilled in the art that in the case of satisfying the driving requirements: the drive roller 211 should be provided as little as possible.
