Description

Technical Field

[0001] This utility model relates to the field of sand mold milling technology, and in particular to a feeding mechanism for sand mold milling. Background Technology

[0002] A sand mold is a tool used to manufacture sand molds, which are important process equipment for casting metal parts. During the sand mold making process, it is usually necessary to match the shape and size of the casting. Therefore, a milling machine is needed to accurately remove and shape the mold material according to the precise dimensions and complex shape of the design, so as to achieve high-precision cavity and core processing, ensure the dimensional accuracy and surface quality of the sand mold, and thus ensure that the cast parts meet the design requirements.

[0003] When a milling machine is milling a sand mold, after the milling machine finishes milling one sand mold, it is necessary to remove the milled sand mold and put in an unfinished sand mold. This results in the milling machine needing frequent manual intervention to place the new sand mold. This feeding method will interrupt the continuity of the milling process and make it difficult to continuously and automatically supply sand molds during the sand mold milling process, thus reducing the overall processing speed of the sand mold. Based on the above problems, this application proposes a feeding mechanism for sand mold milling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for milling sand molds, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The toothed rail is fixedly installed inside the mounting frame. A circular shaft is rotatably installed inside the connecting plate, and a track wheel is fixedly installed on the surface of the circular shaft. A track is overlapped inside the track wheel, and the track is fixedly installed inside the mounting frame.

[0008] Preferably, the movable component includes a U-shaped frame fixedly installed on the top of the mounting base, a drive motor fixedly installed on the left side of the U-shaped frame, a screw fixedly installed at the output end of the drive motor, a threaded sleeve on the surface of the screw, a mounting vertical plate fixedly installed on the top of the threaded sleeve, a guide sleeve fixedly installed at the bottom of the threaded sleeve, a guide rail slidably installed inside the guide sleeve, and the guide rail fixedly installed on the lower side wall of the U-shaped frame.

[0009] Preferably, the tilting feeding assembly includes a geared motor fixedly installed on the left side of the mounting vertical plate. A rotating shaft is fixedly provided at the output end of the geared motor. A tilting plate is fixedly provided on the surface of the rotating shaft. A hydraulic push rod is fixedly provided on one side of the tilting plate. A clamping plate is fixedly provided at the output end of the hydraulic push rod. A guide rod is fixedly provided on the side of the clamping plate near the tilting plate. The guide rod is slidably disposed inside the tilting plate.

[0010] Preferably, the number of track wheels is four, and the four track wheels are symmetrically distributed, with the four track wheels overlapping the track.

[0011] Preferably, there are two placement racks, which are symmetrically distributed, and the placement racks are made of metal.

[0012] Preferably, the rotating shaft has a circular structure and is made of metal.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The feeding mechanism for milling sand molds drives the feeding plate to move through the drive component, so that the sand mold on the left side of the feeding plate enters the milling machine for milling. During this process, the sand mold can be placed on the right side of the feeding plate. When the sand mold on the left side is milled and removed from the milling machine, the feeding plate can drive the sand mold on the right side into the milling machine, so that the sand mold can be continuously milled. This avoids the interruption of the milling process by frequent manual intervention to place new sand molds, and avoids the reduction of the overall processing speed of sand molds due to the inability to continuously and automatically supply sand molds during the sand mold milling process.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-4A feeding mechanism for milling sand molds includes a mounting base 1, a mounting frame 2 fixedly mounted on the top of the mounting base 1, a feeding plate 3 disposed inside the mounting frame 2, a driving assembly disposed at the bottom of the feeding plate 3, a milling machine 25 fixedly mounted on the top of the mounting frame 2, and two placement racks 26 fixedly mounted on the top of the mounting base 1, the two placement racks 26 being symmetrically distributed. The placement racks 26 are made of metal. A moving assembly is disposed on the top of the mounting base 1, and a mounting vertical support is disposed on the top of the mounting base 1 via the moving assembly. Plate 18, the surface of which is provided with a flip-type feeding assembly, the drive assembly includes a mounting plate 4 and a connecting plate 9 fixedly mounted on the bottom of the feeding plate 3, a servo motor 5 fixedly mounted on the front side of the mounting plate 4, a rotating shaft 6 fixedly mounted on the output end of the servo motor 5, a rotating gear 7 fixedly mounted on the surface of the rotating shaft 6, a gear rail 8 meshing on the surface of the rotating gear 7, the gear rail 8 fixedly mounted inside the mounting frame 2, a circular shaft 10 rotatably mounted inside the connecting plate 9, a track wheel 11 fixedly mounted on the surface of the circular shaft 10, and a rail interlocking inside the track wheel 11. The track 12 has four track wheels 11, which are symmetrically distributed and overlap with the track 12. The track 12 is fixedly installed inside the mounting frame 2. The servo motor 5 drives the rotating shaft 6 to drive the rotating gear 7 to roll on the surface of the gear rail 8. This causes the rotating gear 7 to move the loading plate 3 through the rotating shaft 6 and the mounting plate 4. The loading plate 3, through the connecting plate 9 and the circular shaft 10, drives the track wheels 11 to roll on the surface of the track 12. This allows the loading plate 3 to pull the sand mold into the milling machine 25 from the left or right side, thereby... This facilitates the milling machine 25 to mill the sand molds on the left or right side of the feeding plate 3. When milling the sand molds on the top side of the feeding plate 3, the sand molds can be placed on the other side of the feeding plate 3. When the feeding plate 3 moves the milled sand molds out of the milling machine 25, the feeding plate 3 can move the unmilled sand molds into the milling machine 25, so that the sand molds can be milled continuously. This avoids interrupting the milling machine 25 due to feeding the sand molds, and allows more sand molds to be milled in the same amount of time.

[0021] Specifically, the moving component includes a U-shaped frame 13 fixedly mounted on the top of the mounting base 1. A drive motor 14 is fixedly mounted on the left side of the U-shaped frame 13. A screw 27 is fixedly mounted on the output end of the drive motor 14. A threaded sleeve 15 is threaded onto the surface of the screw 27. A mounting vertical plate 18 is fixedly mounted on the top of the threaded sleeve 15. A guide sleeve 16 is fixedly mounted on the bottom of the threaded sleeve 15. A guide rail 17 is slidably mounted inside the guide sleeve 16. The guide rail 17 is fixedly mounted on the lower side wall of the U-shaped frame 13. The tilting feeding component includes components fixedly mounted on the mounting vertical plate 1. 8. The geared motor 19 on the left has a rotating shaft 20 fixedly mounted at its output end. The rotating shaft 20 has a circular structure and is made of metal, which makes it stronger and less prone to deformation and breakage. A flip plate 21 is fixedly mounted on the surface of the rotating shaft 20. A hydraulic push rod 22 is fixedly mounted on one side of the flip plate 21. A clamping plate 23 is fixedly mounted at the output end of the hydraulic push rod 22. A guide rod 24 is fixedly mounted on the side of the clamping plate 23 near the flip plate 21. The guide rod 24 is slidably mounted inside the flip plate 21. The drive motor 14 drives the screw 27 to rotate, causing the screw sleeve 15 to slide the guide sleeve 16 on the surface of the guide rail 17. The screw sleeve 15 then moves the mounting plate 18, which in turn moves the rotating shaft 20 and the reduction motor 19. The rotating shaft 20 then moves the tilting plate 21. The tilting plate 21, via the hydraulic push rod 22 and guide rod 24, moves the clamping plate 23 to different positions on the placement rack 26. The hydraulic push rod 22 then drives the output end to push the clamping plate 23 against the sand. The mold contacts the mold and guides the clamping plate 23 through the guide rod 24. Then, the output end of the geared motor 19 drives the rotating shaft 20 to rotate, so that the rotating shaft 20 drives the flipping plate 21 to rotate 180 degrees. The flipping plate 21 drives the clamping plate 23 to rotate through the hydraulic push rod 22 and the guide rod 24, and drives the sand mold to rotate through the clamping plate 23, so that the sand mold is placed on the top of the loading plate 3. This makes it easy to place the sand molds on the placement rack 26 at different positions on the loading plate 3, thus facilitating continuous milling of the sand mold.

[0022] The feeding mechanism for milling sand molds is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0023] In use: The servo motor 5 drives the output end to rotate the rotating shaft 6, and the rotating shaft 6 drives the rotating gear 7 to roll on the surface of the gear rail 8. The rotating gear 7 drives the mounting plate 4 to move through the rotating shaft 6, and the mounting plate 4 drives the feeding plate 3 to move through the mounting plate 4. The feeding plate 3 drives the circular shaft 10 to move through the connecting plate 9, and the circular shaft 10 drives the track wheel 11 to roll on the surface of the track 12. The track wheel 11 drives the circular shaft 10 to rotate inside the connecting plate 9, so that the feeding plate 3 carries the sand mold into the milling machine 25, and the milling machine 25 mills the sand mold.
