Figures 1 to 7The described embodiments are exemplary and are intended to explain the embodiments of the present invention, but should not be understood as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0039] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0040] In one embodiment of the present invention, Figures 1-2 As shown, an automatic slag blowing equipment for metal die-castings is provided, including a frame 10, a blowing device 20 and a positioning device 30, the blowing device 20 including a lifting cylinder 21, a lifting plate 22 and a plurality of blowing nozzles 23, the lifting cylinder 21 is installed in the frame 10 and its piston rod is set upward, the lifting plate 22 is horizontally arranged and fixedly connected to the piston rod, each of the blowing nozzles 23 is installed on the lifting plate 22, the positioning device 30 is installed on the frame 10 and is located above each of the blowing nozzles 23, the positioning device 30 is used to position the metal die-castings so that the screw holes on the metal die-castings can be aligned with the blowing nozzles 23, and the airflow ejected through the blowing nozzles 23 can blow off the metal slag in the screw holes.

[0041] When the automatic slag blowing equipment for metal die-castings provided by the embodiment of the present invention is working, the metal die-casting that needs to be cleaned of metal debris is first placed on the frame 10, and the screw holes on the metal die-casting are aligned with the various blowing nozzles 23 of the blowing device 20. Finally, the position of the metal die-casting is positioned by the positioning device 30 to prevent it from shaking, etc. Then, after starting the external air pump, air is blown out into the screw holes on the metal die-casting through the blowing nozzle 23. Under the action of the high-pressure airflow, the metal debris in the screw holes of the metal die-casting is blown out of the screw holes, thereby completing the effective and rapid cleaning of the metal debris in the screw holes of the metal die-casting, and the screw holes are clean after cleaning without retaining any metal residue.

[0042] In another embodiment of the present invention, the blowing device 20 further includes multiple polygonal long axes 24 and multiple adjustable air nozzle fixtures 25. Each polygonal long axis 24 is affixed to the lifting plate 22 in the transverse and / or longitudinal directions, and each air nozzle 23 is clamped and secured to the polygonal long axis 24 by an adjustable air nozzle fixture 25. Specifically, the polygonal long axes 24 can be arranged transversely and longitudinally according to actual circumstances. This ensures that the adjustable air nozzle fixtures 25 can be installed at various locations and points. The adjustable air nozzle fixtures 25 are used to facilitate the installation of the air nozzles 23, allowing the air nozzles 23 to blow slag from screw holes at various locations on the metal die-casting. In one arrangement, one polygonal long axis 24 is positioned vertically along the length of the lifting plate 22, and six polygonal long axes 24 are spaced apart in the width direction between two polygonal long axes 24. This arrangement generally satisfies the requirements for blowing slag from screw holes in most metal die-casting structures.

[0043] In another embodiment of the present utility model, the adjustable air nozzle clamp 25 includes an axis clamping block 251 and an air nozzle fixing block 252, the axis clamping block 251 is provided with a deformation hole 2511 and a bottom clamping hole 2512 located at its bottom and adapted to the shape of the polygonal long axis 24 and open, the bottom clamping hole 2512 is connected with the deformation hole 2511, and a first fastener 255 is passed through and connected at the connection between the bottom clamping hole 2512 and the deformation hole 2511, the air nozzle fixing block 252 is connected and fixed to the axis clamping block 251, the air blowing nozzle 23 is installed on the air nozzle fixing block 252, the bottom clamping hole 2512 is sleeved on the polygonal long axis 24 and clamps the polygonal long axis 24 by tightening the first fastener 255. Specifically, the bottom clamping hole 2512 connected to the deformation hole 2511 can be opened to a certain angle under the deformation of the deformation hole 2511, so that the bottom clamping hole 2512 can be easily set outside the polygonal long axis 24 and can effectively slide along the polygonal long axis 24. In this way, by adjusting the position of the shaft clamping block 251 relative to the polygonal long axis 24, the position of the air nozzle fixing block 252 can be adjusted, and then the position of the air nozzle 23 installed on the air nozzle fixing block 252 can be adjusted. After the position of the shaft clamping block 251 is adjusted, the connection between the shaft clamping block 251 and the polygonal long axis 24 is locked by tightening the first fastener 255, which is convenient and practical. The first fastener 255 can be a screw or a bolt.

[0044] In another embodiment of the present utility model, the adjustable air nozzle clamp 25 also includes a polygonal short axis 253 and a short axis fixing block 254. The top of the axis clamping block 251 is provided with a top clamping hole 2513 whose shape is adapted to the shape of the polygonal short axis 253 and is open. The top clamping hole 2513 is connected to the deformation hole, and the connection between the top clamping hole 2513 and the deformation hole 2511 is penetrated and connected with a second fastener 256. The polygonal short axis 253 is inserted into the top clamping hole 2513 and is clamped by the top clamping hole 2513 by tightening the second fastener 256. The air nozzle fixing block 252 is locked on the polygonal short axis 253, and the short axis fixing block 254 presses the air nozzle fixing block 252 and is locked with the polygonal short axis 253. Specifically, the polygonal short axis 253 can be inserted into the top clamping hole 2513 of the shaft clamping block 251 according to actual conditions, thereby adjusting the position of the air nozzle fixing block 252 connected to the polygonal short axis 253. Finally, the relative position of the polygonal short axis 253 and the shaft clamping block 251 is adjusted by tightening the second fastener 256, and the connection between the air nozzle fixing block 252 and the polygonal short axis 253 and the connection between the short axis fixing block 254 and the polygonal short axis 253 are further tightened. In this way, the relative position of the shaft clamping block 251 is adjusted relative to the polygonal short axis 253 and the polygonal long axis 24, respectively, thereby adjusting the position of the air nozzle fixing block 252 in two directions, and further adjusting the position of the air blowing nozzle 23 in two directions, which is flexible and practical.

[0045] Similarly, in this embodiment, because the top clamping hole 2513 is connected to the deformation hole 2511, the top clamping hole 2513 can be opened under the deformation of the deformation hole 2511, which is beneficial for its sleeve cooperation with the polygonal short axis 253.

[0046] In another embodiment of the present invention, the axis direction of the top clamping hole 2513 and the axis direction of the bottom clamping hole 2512 intersect perpendicularly in space. Thus, for example, if the polygon's major axis 24 lies in the X-axis direction, then the polygon's minor axis 253 lies in the Y-axis direction. This allows the position of the air nozzle 23 to be adjusted in both the X and Y-axis directions.

[0047] In another embodiment of the present invention, the blowing device 20 also includes a bottom support plate 26, a middle support plate 27, a top support plate 26, an upper guide sleeve 29a, a lower guide sleeve 29b and a guide shaft 29c, the bottom support plate 26 is fixed on the frame 10, the cylinder body of the lifting cylinder 21 is fixed on the bottom support plate 26, the middle support plate 27 is fixed to the cylinder body of the lifting cylinder 21 and is located above the bottom support plate 26, the upper guide sleeve 29a and the lower guide sleeve 29b are respectively fixed to the corresponding positions of the middle support plate 27 and the bottom support plate 26, the guide shaft 29c passes through the corresponding lower guide sleeve 29b and the upper guide sleeve 29a in sequence and is connected and fixed to the top support plate 26, and the top support plate 26 is connected and fixed to the bottom of the lifting plate 22. Specifically, the lifting cylinder 21 is fixed between the bottom support plate 26 and the middle support plate 27, and then the top support plate 26 is driven to rise and fall by the piston rod of the lifting cylinder 21. The top support plate 26 is guided in the Z-axis direction in cooperation with the guide shaft 29c and the upper guide sleeve 29a and the lower guide sleeve 29b, and finally the lifting and lowering of the lifting plate 22 is controlled, thereby driving the blowing nozzle 23 installed on the lifting plate 22 to rise and fall, so as to meet the slag blowing work of the screw holes of metal die-castings with different structures.

[0048] In another embodiment of the present invention, the positioning device 30 includes a bottom support beam 31, a top positioning shaft 32, a side positioning shaft 33, a side positioning plate 34, a rear positioning shaft 35 and a front adjustable top block 36. The bottom support beam 31 is mounted on the frame 10 and is used to support the metal die-casting. The top positioning shaft 32 is mounted on the frame 10 and is used to press the top of the metal die-casting. The side positioning shaft 33 is mounted on the frame 10 and is used to press one side of the metal die-casting. The side positioning plate 34 is connected to the top positioning shaft 32 and is used to press the other side of the metal die-casting. The rear positioning shaft 35 is connected to the side positioning shaft 33 and is used to press the rear side of the metal die-casting. The front adjustable top block 36 is mounted on the bottom support beam 31 and is used to press the front side of the metal die-casting. Specifically, the metal die-casting is placed and supported on the bottom support beam 31, and then the positions of the top positioning shaft 32, the side positioning shaft 33, the side positioning plate 34, the rear positioning shaft 35 and the front adjustable top block 36 are adjusted to achieve the position limitation of the left and right sides, the front and rear sides and the top side of the metal die-casting. Finally, the front adjustable top block 36 is adjusted to support the metal die-casting. When the slag blowing work is subsequently performed, the metal die-casting will not shake, and the slag blowing work of the screw holes can be achieved with high efficiency and high quality. It should be noted that the side positioning shaft 33 and the side positioning plate 34 are respectively used to limit the position of one left side and the other right side of the metal die-casting.

[0049] In another embodiment of the present invention, a frame strip groove 11 is provided at the top of the frame 10, and the top positioning shaft 32 and the side positioning shaft 33 are respectively locked to the frame 10 via mounting blocks 30a that can be slid into position on the frame strip groove 11 and then fixed. Specifically, the mounting block 30a is directly or indirectly connected to the top positioning shaft 32, and then is locked to the frame strip groove 11 via fasteners after sliding on the frame 10. Similarly, the mounting block 30a is directly or indirectly connected to the side positioning shaft 33, and then is locked to the frame strip groove 11 via fasteners after sliding on the frame 10. In this way, the positions of the top positioning shaft 32 and the side positioning shaft 33 relative to the frame 10 can be adjusted, thereby meeting the requirements for the corresponding positions of the metal die-castings on the frame 10.

[0050] In another embodiment of the present invention, the side of the bottom support beam 31 is provided with a beam-shaped groove 311.

Specifically, the mounting block 30a is directly or indirectly connected to the front adjustable stop block 36, then slides onto the bottom support beam 31 and is locked to the beam-shaped groove 311 via fasteners. This allows the front adjustable stop block 36 to be adjusted in position.

[0051] In another embodiment of the present invention, the side positioning plate 34 slides axially along the top positioning shaft 32 via the mounting block 30a and is then locked to the top positioning shaft 32. The rear positioning shaft 35 slides axially along the side positioning shaft 33 via the mounting block 30a and is then locked to the side positioning shaft 33. Specifically, the mounting block 30a is directly or indirectly connected to the side positioning plate 34, then slides on the top positioning shaft 32 and is then locked to the top positioning shaft 32 via fasteners. This allows the side positioning plate 34 to be adjusted in position.
