DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to solve the problem that the existing traditional cleaning methods are inefficient and easy to damage the mold surface, please refer to Figure 1-Figure 6 , this embodiment provides the following technical solutions:

[0028] The high-precision die-casting machine casting cavity rapid circulation blowing cleaning structure is installed as a whole on a mechanical arm for use. When the upper and lower molds of the high-precision die-casting machine are in the mold opening state, the casting cavity is exposed, and the blowing cleaning structure is controlled by the mechanical arm to extend into the casting cavity to clean the casting cavity. The blowing cleaning structure includes a mounting bracket 1 mounted on the machine wall, one end of the mounting bracket 1 is fixedly connected to a driving motor 11, the output end of the driving motor 11 is fixedly connected to a rotating shaft 12, the end of the rotating shaft 12 is connected to an inclined rod 13 through an inclined extension block 121, and the driving motor When 11 is working, the inclined rod 13 is driven to rotate by the rotating shaft 12, and the center of the inclined rod 13 intersects with the extension line of the rotating shaft 12. Therefore, under the control of the rotating shaft 12, the inclined rod 13 moves in a sand bucket-like path, and the positions of the two ends of the inclined rod 13 are alternately up and down. The impurity collecting cylinder 2 is sleeved on the inclined rod 13, and the end of the inclined rod 13 away from the extension block 121 is fixedly connected with the first connecting block 14. The first connecting block 14 is fixedly engaged with one end of the high-pressure blowing pipe 3. When the first connecting block 14 moves, it drives the high-pressure blowing pipe 3 to move in a circle up and down.

[0029] Movable holes are provided on both sides of the mounting bracket 1, and movable cleaning brushes are connected to the shafts on the movable holes. The movable cleaning brushes include a first cleaning brush 4 and a second cleaning brush 5. In order to limit the impurity collecting barrel 2 from rotating, the first cleaning brush 4 is sleeved with the impurity collecting barrel 2, and short shafts 41 are provided on the upper and lower sides of the inner wall of the first cleaning brush 4. The short shaft 41 is plugged into the impurity collecting barrel 2, which limits the impurity collecting barrel 2 from rotating following the inclined rod 13, and the positions of the upper and lower ends of the impurity collecting barrel 2 cannot be reversed. At the same time, the first cleaning brush 4 follows the impurity collecting barrel 2 to perform a flipping activity to clean the inner wall of the casting cavity. In order to fix the position of the high-pressure blowing pipe 3, the second cleaning brush 5 is sleeved with the high-pressure blowing pipe 3, and the upper and lower ends of the inner wall of the second cleaning brush 5 are provided with a long shaft 51, which is plugged into the side wall of the high-pressure blowing pipe 3 to fix the position of the high-pressure blowing pipe 3 so that it cannot move, but the high-pressure blowing pipe 3 can rotate around the long shaft 51, and at the same time, the second cleaning brush 5 can follow the high-pressure blowing pipe 3 to perform a flipping activity.

[0030] The outer side walls of the first cleaning brush 4 and the second cleaning brush 5 are movably connected to the mounting bracket 1 through an axis, which limits the position of the first cleaning brush 4 and the second cleaning brush 5, so that the first cleaning brush 4 and the second cleaning brush 5 can only rotate around the axis and cannot be displaced.

[0031] A raised ring 31 is provided at the middle position of the high-pressure blowing pipe 3, and a socket movably connected to the long shaft 51 is provided on the raised ring 31. The rotational power of the high-pressure blowing pipe 3 comes from the second connecting block 32 engaged with the first connecting block 14. The second connecting block 32 is connected to one end of the high-pressure blowing pipe 3. A limiting ring groove 321 is provided on the end surface of the second connecting block 32. In order to make the first connecting block 14 engage with the second connecting block 32, a slip ring 141 matching the limiting ring groove 321 is provided on the first connecting block 14. A part of the slip ring 141 engages with the limiting ring groove 321. The high-pressure blowing The end of the tube 3 away from the second connecting block 32 is fixedly connected with a high-pressure nozzle 33, and the high-pressure nozzle 33 sprays high-pressure gas to clean the inner wall of the casting cavity. When the first connecting block 14 follows the inclined rod 13 to rotate in a circle, it pushes the second connecting block 32 to synchronously circle up and down. The second connecting block 32 drives one end of the high-pressure blowing pipe 3 to circle up and down. The middle position of the high-pressure blowing pipe 3 is restricted by the second cleaning brush 5. One end of the high-pressure blowing pipe 3 provided with the high-pressure nozzle 33 is offset from one end of the second connecting block 32 to circle up and down, thereby changing the injection position of the high-pressure nozzle 33 and expanding the cleaning area of ​​the high-pressure nozzle 33.

[0032] The impurity collecting cylinder 2 includes a middle cylinder 21 sleeved with the inclined rod 13, an outer cylinder 22 arranged outside the middle cylinder and an air compressor 23 arranged on the outer cylinder 22. A support frame 211 connected to the outer cylinder 22 is fixedly connected to the middle position of the middle cylinder 21. The support frame 211 is used to connect the outer cylinder 22 and the inner cylinder 21. A filter screen 212 is arranged on the support frame 211. A first conical cylinder 221 and a second conical cylinder 222 are respectively arranged on both sides of the outer cylinder 22. The ends of the first conical cylinder 221 and the second conical cylinder 222 are fixedly connected to the outer wall of the middle cylinder 21. The filter screen 212 and the support frame 211 separate the outer cylinder 22 into two spaces. An impurity collecting bin is formed between the first conical cylinder 221 and the filter screen 212. An impurity inlet hole 2211 is provided at the upper position of a conical cylinder 221, and a negative pressure chamber is formed between the filter screen 212 and the second conical cylinder 222. The negative pressure chamber is connected to the air inlet of the air compressor 23. When the air compressor 23 is working, the air in the negative pressure chamber flows into the air compressor 23, and the impurity collection chamber absorbs gas from the outside through the impurity inlet hole 2211, driving impurities into the impurity collection chamber, and filtering through the filter screen 212, leaving the impurities in the impurity collection chamber, and the air is discharged through the air compressor 23. The output end of the air compressor 23 is connected to an exhaust pipe 231, which passes through the filter screen 212 and the first conical cylinder 221, and is finally connected to the high-pressure blowing pipe 3 to supply air to the high-pressure blowing pipe 3.

[0033] The upper and lower ends of the outer wall of the outer cylinder 22 are provided with jacks matching the short axis 41. The short axis 41 limits the outer cylinder 22 to rotate only along the short axis 41, so that the impurity inlet hole 2211 is always at the upper position of the outer cylinder 22 to prevent impurities in the impurity collection bin from being dumped out. Under the control of the middle cylinder 21, the outer cylinder 22 drives the first tapered cylinder 221 and the second tapered cylinder 222 to alternately change their height positions. At the same time, the first connecting block 14 drives the second connecting block 32 to rotate up and down, so that the two ends of the high-pressure blowing pipe 3 also alternately change their height positions, and the working direction of the high-pressure nozzle 33 is always opposite to the working direction of the impurity inlet hole 2211. In this way, when the high-pressure nozzle 33 blows air to clean impurities, the impurity inlet hole 2211 collects impurities in the opposite direction of the high-pressure nozzle 33, and the airflow in the casting cavity of the high-precision die-casting machine forms a cycle, which will not affect the cleaning of the high-pressure nozzle 33.

[0034] In order to better demonstrate the working process of the high-precision die-casting machine casting cavity rapid cycle air blowing cleaning structure, this embodiment now proposes a working method of the high-precision die-casting machine casting cavity rapid cycle air blowing cleaning structure, including the following steps:

[0035] Step 1: Fix the mounting bracket 1 to the robot arm. After the die-casting machine completes a working cycle, close the die-casting machine's mold clamping device, start the robot arm, and drive the air blowing cleaning structure into the die-casting machine's casting cavity;

[0036] Step 2: Turn on the air compressor 23, the air compressor 23 supplies air to the high-pressure air blowing pipe 3, and the high-pressure gas is ejected through the high-pressure nozzle 33 to clean the inner wall of the casting cavity. The gas in the negative pressure bin flows to the air compressor 23, generating negative pressure, and sucks air into the casting cavity of the die-casting machine through the impurity inlet hole 2211, driving the cleaned impurities to be collected in the impurity collection bin;

[0037] Step three: the driving motor 11 is turned on, the inclined rod 13 rotates, and the high-pressure nozzle 33 on the high-pressure blowing pipe 3 is driven to rotate through the first connecting block 14 and the second connecting block 32, so as to change the blowing position and expand the cleaning range. The two ends of the middle cylinder 21 connected with the inclined rod 13 rotate in circles alternately, and the working direction of the inlet hole 2211 also changes accordingly, and impurities are adsorbed and collected in the opposite direction of the high-pressure nozzle 33. The first cleaning brush 4 and the second cleaning brush 5 shake with the high-pressure blowing pipe 3 and the outer cylinder 22 to clean the side wall of the casting cavity of the die-casting machine, accelerate the shedding of impurities, and at the same time, the raised impurities are conveniently absorbed by the inlet hole 2211.
