Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically a device for treating sand removal from casting blanks. Background Technology

[0002] The casting process involves pouring molten metal into a mold made of molding sand, and then cooling and solidifying it to obtain a casting with the desired shape and properties. During the casting process, to reduce manual labor and improve production efficiency, a sand removal machine is typically used to quickly separate the workpiece from the molding sand.

[0003] A drum sand removal machine is a common piece of equipment for separating workpieces from molding sand. Because the side of the drum has a mesh structure, the molding sand passes through the drum as it rotates, while the workpiece remains inside. The workpiece is automatically discharged by a spiral plate fixed to the inner wall of the drum. During the discharge process, the workpiece obstructs the discharge speed of the molding sand, causing some of the molding sand and workpiece to come out of the discharge port of the drum together under the action of the spiral plate. This requires the workpiece to be separated from the residual molding sand later, which wastes a lot of time and reduces the production efficiency of the workpiece. Utility Model Content

[0004] The purpose of this utility model is to provide a sand removal treatment device for casting blanks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A casting blank sand removal treatment device includes two symmetrically arranged support frames, a roller and two covers. The inner wall of the roller is fixedly connected with multiple baffles at equal angles in a ring. The baffles are mesh structures. The inside of the roller is provided with a discharge mechanism for removing the workpiece from the roller. The side of the support frame is provided with a vibration mechanism for vibrating the discharge mechanism.

[0007] The discharge mechanism includes a rectangular frame located inside the drum and penetrating through two covers. The bottom surface of the rectangular frame has a mesh structure. A movable shell is slidably connected inside the rectangular frame. A push plate is slidably connected inside the movable shell. Discharge ports are opened through both ends of the bottom surface of the rectangular frame.

[0008] Furthermore, the top of each of the two long sides of the rectangular frame is provided with a sliding hole, and each end of each of the two long sides of the rectangular frame is fixedly connected to a fixing block. A reciprocating screw that is screwed through and engaged with the movable shell is rotatably connected between the two fixing blocks at opposite positions.

[0009] Furthermore, one end of the reciprocating lead screw passes through a fixed block at a corresponding position and is fixedly connected to a bevel gear. A dual-axis motor is fixedly connected to one end of the rectangular frame. Both output ends of the dual-axis motor are fixedly connected to bevel gears that mesh with bevel gears at the corresponding positions.

[0010] Furthermore, both sides of one end face of the rectangular frame are fixedly connected to a second fixed block that rotates through the two output ends of the dual-axis motor.

[0011] Furthermore, both ends of the side of the support frame are fixedly connected to rectangular sleeves, and L-shaped plates that are fixedly connected to the rectangular frame are slidably connected inside the rectangular sleeves.

[0012] Furthermore, the vibration mechanism includes a connecting plate fixedly connected to a rectangular frame, and two symmetrical sliding rods fixedly connected to the corresponding covers on one side of the connecting plate. A spring is fixedly connected between the connecting plate and the corresponding covers and outside the sliding rods.

[0013] Furthermore, a fixing plate is fixedly connected to one side of one of the covers, a drive motor is fixedly connected to the top surface of the fixing plate, the output end of the drive motor passes through the fixing plate and is fixedly connected to a cam that abuts against the side of the connecting plate, and two symmetrical support blocks are fixedly connected to one end of the fixing plate and are rotatably connected to the ends of the slide rods at corresponding positions.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The rotation of the drum filters out most of the molding sand. Then, the vibration of the rectangular frame causes the molding sand that has fallen inside to fall back into the drum. At the same time, the movement of the push plate pushes the workpieces inside the rectangular frame out of the two discharge ports. Through two filtrations of the molding sand, the surface of the pushed workpieces is cleaner, minimizing the need for secondary operations and thus improving the production efficiency of the workpieces.

[0022] 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.

[0023] Please see Figure 1 - Figure 5 In this embodiment of the present invention, a casting blank sand removal treatment device includes two symmetrically arranged support frames 1, a roller 2, and two covers 3. The roller 2 rotates between the two support frames 1. The covers 3 are rotatably connected to the ends of the roller 2. A feed pipe is fixed through the side of the covers 3. Multiple baffles 21 are fixedly connected at equal angles to the inner wall of the roller 2. The baffles 21 have a mesh structure. The inside of the roller 2 is provided with a discharge mechanism 4 for removing the workpiece from the inside of the roller 2. The side of the support frame 1 is provided with a vibration mechanism 5 for vibrating the discharge mechanism 4. The discharge mechanism 4 includes a rectangular frame 41 located inside the roller 2 and penetrating through the two covers 3. The bottom surface of the rectangular frame 41 has a mesh structure. A movable shell 42 is slidably connected inside the rectangular frame 41. A push plate 43 is slidably connected inside the movable shell 42. Discharge ports 411 are opened through both ends of the bottom surface of the rectangular frame 41.

[0024] Specifically, firstly, an external drive mechanism drives the roller 2 to rotate between two support frames 1. Then, the feed pipe 32 is connected to an external feed hopper, which can be positioned above the roller 2. When the workpiece and molding sand enter the roller 2, the rotation of the roller 2 causes the workpiece and molding sand to roll inside. During the rolling process, the molding sand passes through the roller 2 and falls down (a collection box for collecting molding sand can be placed below the roller 2). The workpiece and some molding sand move to the top of the roller 2 under the action of the baffle 21. Since the baffle 21 has a mesh structure, some molding sand on the baffle 21 falls back into the roller 2. After the workpiece moves to the top of the roller 2 under the action of the baffle 21, it falls into the rectangular frame 41 under its own gravity. The inner bottom surface of the rectangular frame 41 has a mesh structure. Therefore, the molding sand falling into the rectangular frame 41 falls into the drum 2 when the rectangular frame 41 is vibrated by the vibration mechanism 5, while the workpiece remains in the rectangular frame 41. The push plate 43 is driven by the moving shell 42 to move back and forth in the rectangular frame 41, which can push the workpiece out from the two discharge ports 411. This device can filter out most of the molding sand by rotating the drum 2. Then, the vibration of the rectangular frame 41 can make the molding sand that has fallen into it fall back into the drum 2. At the same time, the movement of the push plate 43 can push the workpiece in the rectangular frame 41 out from the two discharge ports 411. Through two filtrations of molding sand, the surface of the pushed workpiece can be cleaner, and secondary operations on the workpiece can be avoided as much as possible, thereby improving the production efficiency of the workpiece.

[0025] Example 1

[0026] like Figure 4 As shown, in this embodiment, sliding holes 412 are provided through the top of the two long side surfaces of the rectangular frame 41. Fixing blocks 413 are fixedly connected to both ends of the two long side surfaces of the rectangular frame 41. A reciprocating screw 44, which is screwed through and engaged with the movable shell 42, is rotatably connected between the two fixing blocks 413 at opposite positions. One end of the reciprocating screw 44 passes through the fixing block 413 at the corresponding position and is fixedly connected to a bevel gear 441. A dual-axis motor 45 is fixedly connected to one end face of the rectangular frame 41. A bevel gear 451, which meshes with the bevel gear 441 at the corresponding position, is fixedly connected to both ends of the rectangular frame 41. Fixing blocks 414, which rotate through and are engaged with the two output ends of the dual-axis motor 45, are fixedly connected to both sides of one end face of the rectangular frame 41. A rectangular sleeve 11 is fixedly connected to both ends of the side surface of the support frame 1. An L-shaped plate 12, which is fixedly connected to the rectangular frame 41, is slidably connected inside the rectangular sleeve 11.

[0027] In this embodiment, the two reciprocating lead screws 44 can be rotated by the dual-axis motor 45. The two rotating reciprocating lead screws 44 can cause the moving shell 42 to drive the push plate 43 to move back and forth within the rectangular frame 41, thereby automatically discharging the workpiece. The rectangular frame 41 can be fixed by the L-shaped plate 12 and the rectangular sleeve 11 to prevent the roller 2 from rotating the rectangular frame 41 together.

[0028] Example 2

[0029] like Figure 5 As shown, in this embodiment, the vibration mechanism 5 includes a connecting plate 51 fixedly connected to the rectangular frame 41. Two symmetrical sliding rods 52, which are fixedly connected to the corresponding covers 3, slide through one side of the connecting plate 51. A spring 53 is fixedly connected between the connecting plate 51 and the corresponding cover 3, and located outside the sliding rods 52. A fixing plate 31 is fixedly connected to the side of one of the covers 3. A drive motor 54 is fixedly connected to the top surface of the fixing plate 31. The output end of the drive motor 54 passes through the fixing plate 31 and is fixedly connected to a cam 55 that abuts against the side of the connecting plate 51. Two symmetrical support blocks, which are rotatably connected to the ends of the corresponding sliding rods 52, are fixedly connected to one end of the fixing plate 31.

[0030] In this embodiment, the cam 55 can be rotated and struck by the connecting plate 51 by the drive motor 54, so that the connecting plate 51 can move. Then, under the action of the spring 53, the connecting plate 51 can reciprocate and vibrate. Since the connecting plate 51 is fixedly connected to the rectangular frame 41, the reciprocating connecting plate 51 can drive the rectangular frame 41 to reciprocate within the drum 2, so that the molding sand that has fallen into the rectangular frame 41 can fall back into the drum 2.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
