[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] See also Figure 1-6The utility model provides a technical solution: a self-vibrating bottom sand box, including a box body 10, a placement box 20, a discharge port 201, a collection box 202, a feed port 203, a feed box 30, a motor 40, a rotating shaft 401, a stirring rod 402, a discharge port 1 403, a baffle 404, a discharge port 2 405, a connecting rod 50, a spring 501, a receiving plate 502, a convex block 1 503 and a convex block 2 504;
[0034] The bottom leakage sand box is convenient for loading, and the specific implementation method is as follows:
[0035] The box body 10 is configured as a hollow square shell, and the inner wall of the box body 10 is slidably connected with a placement box 20, and a discharge port 201 is embedded in the bottom of the placement box 20. A collection box 202 is slidably installed on the inner bottom surface of the box body 10, and a rotating mechanism is arranged inside the feed box 30, and the rotating mechanism includes: a motor 40 is installed on the surface of the feed box 30, and a rotating shaft 401 is fixedly connected to the end of the output shaft of the motor 40, and a stirring rod 402 is sleeved and installed on the surface of the rotating shaft 401, and a discharge port 403 is embedded in the bottom of the feed box 30, and the end of the rotating shaft 401 passes through the bottom of the feed box 30 and is connected to a baffle 404, and the baffle 4 04 is embedded with a feed port 2 405, the end of the rotating shaft 401 is fixedly connected with a protrusion 2 504, and the position of the protrusion 2 504 and the protrusion 1 503 are correspondingly arranged, and the ends of the protrusion 2 504 and the protrusion 1 503 are arranged in a circular structure, the receiving plate 502 is arranged correspondingly to the position of the feed port 1 403, and the surface of the receiving plate 502 is arranged with an arc mechanism, and the receiving plate 502 is arranged correspondingly to the position of the placement box 20, the rotating shaft 401 is rotatably connected to the feed box 30, and the surface of the baffle 404 is rotatably connected to the bottom of the feed box 30, and the positions of the feed port 2 405 and the feed port 1 403 are staggered.
[0036] The placing box 20 is pulled outwards, and the placing box 20 is pulled out from the inside of the box body 10, and the casting mold is placed inside the placing box 20. At this time, the placing box 20 is pushed inwards, so that the placing box 20 moves inwards on the surface of the collecting box 202, and the placing box 20 is moved back to the inside of the box body 10. When it is necessary to add casting sand, the air between the feeding box 30 and the box body 10 is extracted through an external vacuum machine to generate a negative pressure state in the space, and the motor 40 is started. The motor 40 drives the rotating shaft 401 to rotate inside the feeding box 30, and the rotating shaft 401 drives the stirring rod 402 to rotate in the feeding box 30. The interior of the feed box 30 rotates to stir the casting sand inside the feed box 30 to prevent the casting sand from agglomerating. The rotating shaft 401 drives the baffle 404 to rotate, and the baffle 404 drives the surface discharge port 2 405 to rotate. When the positions of the discharge port 2 405 and the discharge port 1 403 overlap each other, the casting sand inside the feed box 30 enters the interior of the discharge port 1 403, falls through the discharge port 1 403 and the discharge port 2 405, and falls on the surface of the receiving plate 502. When the discharge port 2 405 and the discharge port 1 403 are staggered, the casting sand cannot fall into the interior of the box body 10.
[0037] The bottom sand box can conveniently scatter the casting sand inside the collection box 202. The specific implementation is as follows:
[0038] A feed box 30 is embedded in the surface of the box body 10, and a vibration mechanism is arranged inside the box body 10, and the vibration mechanism includes: a connecting rod 50 is symmetrically fixedly connected to the inner wall of the box body 10, and a spring 501 is connected to the bottom of the connecting rod 50, and the other end of the spring 501 is fixedly connected to a receiving plate 502, and a protrusion 1 503 is fixedly connected to the surface of the receiving plate 502, the placement box 20 is slidably connected to the box body 10, and the bottom of the placement box 20 is in contact with the surface of the collecting box 202, and the collecting box 202 is slidably connected to the placement box 20, the interior of the placement box 20 is arranged as an inclined plane, and the discharge port 201 is arranged at the lowest point of the plane of the placement box 20, and the positions of the discharge port 201 and the feed port 203 are staggered, and the end of the rotating shaft 401 is fixedly connected with a protrusion 2 504, and the position of the protrusion 2 504 and the protrusion 1 503 are arranged correspondingly, and the ends of the protrusion 2 504 and the protrusion 1 503 are arranged as circular structures.
[0039] When the rotating shaft 401 rotates, the rotating shaft 401 drives the second protrusion 504 to rotate. When the second protrusion 504 rotates to the side of the first protrusion 503, the second protrusion 504 causes an impact on the first protrusion 503, and the second protrusion 504 drives the first protrusion 503 to move downward, so that the first protrusion 503 drives the receiving plate 502 to move downward. At this time, the receiving plate 502 drives the spring 501 to extend, and the position of the second protrusion 504 and the first protrusion 503, the impact of the second protrusion 504 on the first protrusion 503 disappears, and the thrust received by the spring 501 disappears. The spring 501 rebounds and drives the receiving plate 502 to move up and down. At the same time, the casting sand falls on the surface of the receiving plate 502, and the receiving plate 502 drives the casting sand on the surface to vibrate, so that the casting sand moves along the surface of the receiving plate 502, and the casting sand is scattered inside the placement box 20 and falls on the surface of the casting mold.
[0040] When the casting is completed, the placement box 20 is pulled outward, and the placement box 20 drives the discharge port 201 to move on the surface of the collection box 202. When the collection box 202 drives the discharge port 201 to move to the feed port 203, the casting sand inside the collection box 202 enters the feed port 203 through the discharge port 201, and falls into the collection box 202 through the feed port 203. Blocks are provided on the surface of the collection box 202, and the block can be pulled out to clean the collection box 202.
[0041] Working principle: When using the self-vibrating bottom leakage sand box, a receiving plate 502, a protrusion 1 503 and a protrusion 2 504 are provided, so that the foundry sand can be easily scattered inside the collection box 202, and the provision is made to facilitate the loading of the sand, thereby increasing the overall practicality.
[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
