Description

Technical Field

[0001] This utility model relates to the field of casting processing equipment, and in particular to a sand casting device for casting processing. Background Technology

[0002] Casting is the process of pouring molten metal into a molded cavity that conforms to the shape of the part, allowing it to cool and solidify, to obtain a part or blank. A casting obtained by casting is called a casting.

[0003] In casting, a sand mold needs to be made first. Before making the sand mold, the sand needs to be sand-turned to break up any lumps in the sand, so as to avoid the lumps affecting the casting effect. After searching, a Chinese patent with application number 202221004396.3 was found, which discloses "a sand-turning device for casting processing, including a barrel, a motor fixedly installed at the bottom of the barrel, a rotating rod fixedly connected to the output shaft of the motor, and the rotating rod passing through the barrel and extending to the outside. Several rotating plates are circumferentially connected to the rotating rod, and a screening mechanism is also included. The screening mechanism is fixedly installed on the barrel and communicates with the inside of the barrel. The screening mechanism includes a screening cylinder, a screen, a ring plate, a gear and an external gear ring". However, when the sand-turning device falls into the barrel, the sand at the top is difficult to contact the rotating plates, resulting in incomplete sand-turning. Therefore, in order to solve this problem, a sand-turning device for casting processing is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sand casting device for casting processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sand-turning device for casting includes a base plate, a support plate mounted on the top of the base plate, a sand-turning cylinder hinged to the top of the support plate, an electric telescopic rod mounted on the top of the base plate, a roller rotatably mounted on the piston rod end of the electric telescopic rod, a second bearing plate mounted on the bottom of the outer wall of the sand-turning cylinder, and a groove formed at the bottom of the second bearing plate, with the roller rotatably mounted in the groove. An installation shaft is rotatably installed inside the sand-casting cylinder. Several flaps are installed on the outer wall of the installation shaft, and several rubber rods are installed on the side of the flaps. Several through holes are opened on the side of the flaps.

[0006] Preferably, a motor is installed on the side of the sand-casting cylinder, the output shaft of the motor is inserted into the sand-casting cylinder and connected to the mounting shaft, and a roller frame is installed at the end of the piston rod of the electric telescopic rod, with the roller rotatably mounted on the roller frame.

[0007] Preferably, a protective shell is installed on the side of the sand casting cylinder, and the motor is located inside the protective shell.

[0008] Preferably, a bearing is installed on the inner wall of the sand casting cylinder, and the end of the mounting shaft is installed on the inner ring of the bearing.

[0009] Preferably, an mounting plate is mounted on the outer wall of the mounting shaft, and a flap is mounted on the mounting plate.

[0010] Preferably, the top of the outer wall of the sand-casting cylinder is connected to a feed port, and the bottom of the outer wall of the sand-casting cylinder is connected to a discharge port. Both the feed port and the discharge port are equipped with electronic valves.

[0011] Preferably, a first bearing plate is installed at the bottom of the outer wall of the sand casting cylinder, and the top of the support plate is hinged to the bottom of the first bearing plate.

[0012] Preferably, a collection box is installed on the top of the base plate, the collection box is located directly below the discharge port, and several mounting holes are opened on the top of the base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the piston rod of the electric telescopic rod retracts and extends, which can repeatedly tilt the sand-turning cylinder, causing the sand inside the cylinder to roll. This allows the rolling sand to collide with the rubber rod, ensuring the thorough removal of lumps from the sand. Furthermore, the rotating flap can turn the rolling sand inside the cylinder back up to the top, allowing the flap to turn the sand that has fallen to the bottom multiple times. The rolling sand inside the cylinder mixes the sand, ensuring thorough sand turning and guaranteeing that all sand inside the cylinder can undergo multiple turning processes.

[0014] 2: In this utility model, the collision between the rubber rod and the sand body breaks up the lumps in the sand body, which can remove the lumps in the sand body. When the flip plate is processing the sand body, the sand body is filtered through the through holes on the side of the flip plate. If the diameter of the lumps in the sand body is larger than the diameter of the through holes, they cannot pass through. The lumps will then collide with the rubber rod on the side of the flip plate again to break up and remove the lumps in the sand body, thus ensuring the thorough removal of lumps in the sand body. In conjunction with the flip plate, the sand body in the flipping cylinder is stirred, which can make the sand body in the flipping cylinder evenly mixed. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-5 A sand-turning device for casting processing includes a base plate 1, a support plate 3 installed on the top of the base plate 1, a sand-turning cylinder 5 hinged to the top of the support plate 3, an electric telescopic rod 11 installed on the top of the base plate 1, a roller 14 rotatably installed at the piston rod end of the electric telescopic rod 11, a second bearing plate 13 installed at the bottom of the outer wall of the sand-turning cylinder 5, a groove 15 opened at the bottom of the second bearing plate 13, and the roller 14 is rolled in the groove 15. An installation shaft 16 is rotatably installed inside the sand casting cylinder 5. Several flaps 18 are installed on the outer wall of the installation shaft 16. Several rubber rods 20 are installed on the side of the flaps 18. Several through holes 21 are opened on the side of the flaps 18.

[0019] As a technical optimization of this utility model, a motor 6 is installed on the side of the sand casting cylinder 5. The output shaft of the motor 6 is inserted into the sand casting cylinder 5 and connected to the mounting shaft 16. A roller frame 12 is installed at the end of the piston rod of the electric telescopic rod 11, and the roller 14 is rotatably mounted on the roller frame 12.

[0020] As a technical optimization of this utility model, a protective shell 7 is installed on the side of the sand casting cylinder 5, and the motor 6 is located inside the protective shell 7. The protective shell 7 can provide protection for the motor 6.

[0021] As a technical optimization of this utility model, a bearing 17 is installed on the inner wall of the sand casting cylinder 5, and the end of the mounting shaft 16 is installed on the inner ring of the bearing 17. The bearing 17 can provide guidance and support for the mounting shaft 16.

[0022] As a technical optimization of this utility model, an mounting plate 19 is installed on the outer wall of the mounting shaft 16, and a flap 18 is installed on the mounting plate 19. The mounting plate 19 facilitates the connection between the flap 18 and the mounting shaft 16.

[0023] As a technical optimization of this utility model, the top of the outer wall of the sand casting cylinder 5 is connected to the feed port 8, and the bottom of the outer wall of the sand casting cylinder 5 is connected to the discharge port 9. Both the feed port 8 and the discharge port 9 are equipped with electronic valves.

[0024] As a technical optimization of this utility model, a first bearing plate 4 is installed at the bottom of the outer wall of the sand casting cylinder 5, and the top of the support plate 3 is hinged to the bottom of the first bearing plate 4.

[0025] As a technical optimization of this utility model, a collection box 10 is installed on the top of the base plate 1. The collection box 10 is located directly below the discharge port 9. Several mounting holes 2 are opened on the top of the base plate 1. The mounting holes 2 can facilitate the installation of the base plate 1, thereby facilitating the installation of this device.

[0026] When this utility model is in use, if it is necessary to perform sand turning treatment on the sand body, first open the electronic valve in the feed port 8 and introduce the sand body that needs to be turned into the sand turning cylinder 5 through the feed port 8.

[0027] At this time, the motor 6 is started. The output shaft of the motor 6 drives the mounting shaft 16 to rotate, and the mounting shaft 16 drives the mounting plate 19 to rotate. The mounting plate 19 then drives the flip plate 18 to rotate. The rotation of the flip plate 18 is used to flip the sand in the sand-flipping cylinder 5. The sand in the sand-flipping cylinder 5 will collide with the rubber rod 20 on the side of the flip plate 18 when it is flipped. The collision between the rubber rod 20 and the sand breaks up the lumps in the sand and removes them. When the flip plate 18 is flipping the sand, the sand is filtered through the through hole 21 on the side of the flip plate 18. If the diameter of the lumps in the sand is larger than the diameter of the through hole 21, they cannot pass through. The lumps will collide with the rubber rod 20 on the side of the flip plate 18 again and break up the lumps in the sand, thus ensuring the thorough removal of the lumps in the sand. In conjunction with the flip plate 18, the sand in the sand-flipping cylinder 5 is stirred and mixed evenly.

[0028] Furthermore, while the flip plate 18 flips the sand inside the sand-turning cylinder 5, the electric telescopic rod 11 is activated. The piston rod of the electric telescopic rod 11 pushes the roller 14 to roll in the groove 15, which allows the sand-turning cylinder 5 to rotate around the hinge point with the support plate 3, thereby tilting the sand-turning cylinder 5. By retracting and extending the piston rod of the electric telescopic rod 11, the sand-turning cylinder 5 can be tilted repeatedly, causing the sand inside the sand-turning cylinder 5 to roll. This allows the rolling sand inside the sand-turning cylinder 5 to collide with the rubber rod 20, ensuring... The comprehensiveness of sand removal is ensured by the rotation of the flap 18, which flips the sand rolling inside the sand-turning cylinder 5. This allows the sand that has fallen to a lower position to be flipped back to the top, enabling the flap 18 to perform multiple sand-turning processes on the sand that has fallen to a lower position. The rolling sand within the sand-turning cylinder 5 mixes the sand, thus ensuring the comprehensiveness of the sand-turning process. This ensures that all sand within the sand-turning cylinder 5 can undergo multiple sand-turning processes, guaranteeing the comprehensiveness of the sand-turning process.

[0029] After the sand in the sand-turning cylinder 5 has been turned, the discharge port 9 is lower than the second bearing plate 13 by using the electric telescopic rod 11. At this time, the electronic valve in the discharge port 9 is opened, and the sand in the sand-turning cylinder 5 can roll towards the discharge port 9 in the inclined sand-turning cylinder 5 and be discharged through the discharge port 9 into the collection box 10, which facilitates the discharge of the sand in the sand-turning cylinder 5.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
