[0057] An extension plate 20 is horizontally arranged on the outer side of the cleaning rack 4. A long cylindrical moving cylinder 21 is horizontally arranged at the bottom of the extension plate 20.

A lifting member 26 is vertically movably passed through the lifting opening 25. The outer wall of the lifting member 26 is movably attached to the inner wall of the lifting opening 25. A stable part 27 is vertically arranged at the top of the lifting member 26, and an anti - detachment part 28 is horizontally arranged at the bottom. An operation part 29 in a T - shape is arranged at the top of the stable part 27;

[0060] Two horizontally arranged horizontal cylinders 30 with a U - shaped longitudinal section are horizontally arranged at the top of the moving cylinder 21. Horizontal rods 31 are arranged in both of the two horizontal cylinders 30. The outer wall of the horizontal rod 31 is movably attached to the inner wall of the horizontal cylinder 30 and the top of the moving cylinder 21. A translation cylinder 32 is vertically arranged between the outer ends of the two horizontal rods 31. The outer wall of the stable part 27 is movably attached to the inner wall of the translation cylinder 32. An elastic member 33 that is continuously in an extended state is arranged between the inner side of the translation cylinder 32 and the outer side of the cleaning rack 4;

[0061] When the bottom of the stable part 27 is inserted into the stable opening 24 in cooperation, the drag - reducing member 19 at the inner end of the first moving part 5 abuts against the workpiece table 1. When the inner side of the stable part 27 abuts against the outer end of the moving cylinder 21, the outer side of the first moving part 5 abuts against the inner end of the moving cylinder 21, and the drag - reducing member 19 at the inner end of the first moving part 5 is in a separated state from the workpiece table 1.

[0062] The present invention also provides a method for cleaning a milling machine workpiece table 1 as described in any one of the above, including the following steps:

[0063] S1, respectively clamp the first moving part 5 and the second moving part 6 at both ends of the cleaning rack 4 into the two guide rails 2 on both sides;

[0064] S2. Drive the cleaning rack 4 in the downstream direction, and enable a connecting member 8 and a scraping member 7 to move into each positioning groove 3. Meanwhile, as the cleaning rack 4 moves, the scraping member 7 drives the iron filings in the positioning groove 3 to move downstream;

[0065] S3. The scraping member 7 drives the iron filings in the positioning groove 3 to the outside, completing the cleaning of the positioning groove 3.

[0066] The present invention also provides a milling machine for producing mold parts, including a cleaning system for a milling machine workpiece table as described in any one of the above. The workpiece table 1 is used to fix the mold parts. It should also be understood that the cleaning system of the present application can be used for the workpiece tables 1 of all milling machines, including the production of mold parts (not limited to specific parts).

[0067] For the cleaning system of a milling machine workpiece table provided by the present invention, when cleaning the workpiece table 1, first, the first moving part 5 and the second moving part 6 at both ends of the cleaning rack 4 are respectively clamped between the two guide rails 2 on both sides; then drive the cleaning rack 4 in the downstream direction, and enable a connecting member 8 and a scraping member 7 to move into each positioning groove 3. Meanwhile, as the cleaning rack 4 moves, the scraping member 7 drives the iron filings in the positioning groove 3 to move downstream; the scraping member 7 drives the iron filings in the positioning groove 3 to the outside, completing the cleaning of the positioning groove 3. That is, the entire process only needs to move the cleaning rack 4 along the length direction of the workpiece table 1 to clean all the positioning grooves 3. Although the shape of the positioning groove 3 is an inverted T shape, since the bottom and both ends of the scraping member 7 are attached to the inner wall of the positioning groove 3, the cleaning effect of the positioning groove 3 is better.

[0068] During actual operation, before cleaning, the outer side of the first moving part 5 at this time abuts against the inner end of the movable cylinder 21, and the bottom of the stabilizing part 27 abuts against the top of the movable plate 22. Meanwhile, its inner side abuts against the outer end of the movable cylinder 21. Therefore, the distance between the first moving part 5 and the second moving part 6 at this time is slightly greater than the width of the workpiece table 1, and it is relatively convenient to align the first moving part 5 and the second moving part 6 at the upstream end of the workpiece table 1; then move the cleaning rack 4 downstream, so that the second moving part 6 is clamped between the two guide rails 2 on the corresponding side. At this time, the resistance reducing members 19 (which can be spherical or columnar) at the top and bottom of the first moving part 5 also abut against the guide rails 2.

[0069] Then, simply pull up the operating part 29. At this time, the stabilizing part 27 is lifted, and the top of the anti - detachment part 28 touches the lower side of the movable cylinder 21. When the bottom of the stabilizing part 27 is slightly higher than the movable cylinder 21, under the pulling force of the elastic member 33, the first moving part 5, the translation cylinder 32, the stabilizing part 27, and the lifting member 26 all move towards the workpiece table 1. During the movement, after the lifting member 26 passes through the card - entrance 23 until it touches the inner side of the stabilizing port 24, at the same time, the resistance - reducing member 19 at the inner end of the first moving part 5 just touches the outer side of the workpiece table 1. Then, press down the operating part 29 so that the stabilizing part 27 is inserted into the stabilizing port 24. At this time, the position of the first moving part 5 is fixed, making the cleaning frame 4 stably connected to the workpiece table 1.

[0070] Both the first moving part 5 and the second moving part 6 have a certain length. When the stabilizing part 27 is inserted into the stabilizing port 24, at this time, the scraping part 8a, the scraping member 7, etc. are still outside the positioning groove 3, but it can still ensure that the cleaning frame 4 can only move along the downstream. During the subsequent movement of the cleaning frame 4, the scraping part 8a, the volume - increasing part 8b, the scraping member 7, the first cylinder 11, the second cylinder 13, etc. sequentially enter the positioning groove 3.

[0071] During the process of moving the stabilizing part 27 up and down, the anti - detachment part 28 can prevent the stabilizing part 27 from rising too high. At the same time, since the translation cylinder 32 can only move horizontally, during the whole use process, the elastic member 33 remains in a horizontal state and will not bend. In this way, the position stability of the stabilizing part 27 is ensured, and at the same time, it can also prevent the scraping part 8a, etc. from having a relative interaction with the inner wall of the positioning groove 3, ensuring the stable use of each structure.

[0072] During the movement of the cleaning frame 4, first, the material - cleaning part 18 on the downstream side acts on the top of the workpiece table 1. At this time, the iron filings on the top of the workpiece table 1 are acted on by the side of the material - cleaning part 18 and can be driven into the positioning groove 3. Then, the scraping part 8a can scrape the iron filings on the inner wall of the upper groove 3a (part of the iron filings adhere to the inner wall of the upper groove 3a under the action of the coolant), making this part of the iron filings also fall into the lower groove 3b. After that, the iron filings in the lower groove 3b are driven by the scraping member 7 to move downstream. The volume - increasing part 8b makes the distance between the scraping part 8a and the scraping member 7 larger. Therefore, if there are more iron filings, it can also better make the iron filings be between the scraping member 7 and the volume - increasing part 8b, that is, prevent the accumulated iron filings from being located below the scraping part 8a and / or the material - cleaning part 18, ensuring the removal of iron filings.

[0073] Moreover, during the movement of the cleaning rack 4, first, there is a large interaction force between the first cylinder 11 and one inner wall of the upper groove 3a, enabling the first cylinder 11 to rotate as the cleaning rack 4 moves; at the same time, the bottom of the first cylinder 11 is in a tightly pressed state with the second cylinder 13. Therefore, the second cylinder 13 is driven by the first cylinder 11 to rotate; at the same time, the second cylinder 13 can drive the third cylinder 16 to rotate, and the bottom of the third cylinder 16 moves towards the downstream direction, playing a role in cleaning the iron filings at the bottom of the lower groove 3b, thereby making the cleaning effect of the iron filings better. During the movement of the third cylinder 16, the acting force direction applied by the second cylinder 13 to the third cylinder 16 is opposite to the acting force direction applied by the lower groove 3b to the third cylinder 16. At this time, through design, the acting force of the second cylinder 13 can be made larger (the third cylinder 16 is in direct contact with the lower groove 3b, mainly for cleaning the iron filings). Moreover, during the movement of the cleaning rack 4, the extension rack 14 and the leak-proof part 17 can also clean the inner wall of the lower groove 3b, also making the cleaning effect better.

[0074] It should also be supplemented that all "settings" and similar descriptive words in this application (especially in the specification) express that there is a connection relationship between two structures, but there is no excessive limitation on the specific means by which the two are connected, and it is usually a conventional connection means, that is, it should be understood that this means is the prior art and does not need to be elaborated too much. For example, "n is provided on m" only expresses that there is an n structure on the m structure, and whether the two are connected by welding, riveting, adhesive connection or integral molding is within the protection scope of this application; another example, "y is rotatably provided on x" only expresses that y and x can rotate relative to each other, and as for whether the two are rotationally connected by a bearing, or y directly passes through x and is rotationally connected to x, or other achievable ways, they are all within the protection scope of this application.

[0075] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention based on the above disclosure are within the protection scope of the claims.
