Description

Technical Field

[0001] This utility model relates to the field of casting production machinery and equipment technology, and in particular to a sand box turning machine that can prevent damage to castings. Background Technology

[0002] A sand box flipping machine is a mechanical device used in the casting production process to flip sand boxes. In the casting process, the sand box (also called the mold box) is an important tool used to hold casting sand and form the mold for castings. When the sand box needs to be flipped to remove or replace castings, the sand box flipping machine provides efficient and safe operation.

[0003] Patent application publication number CN206253635U discloses a sand box turning machine, including a U-shaped base and a U-shaped placement frame. Fixed shafts are fixedly installed on both sides of the U-shaped placement frame, and the fixed shafts are mounted on the U-shaped base. One end of each fixed shaft passes through the U-shaped base to the outside, and a turntable is fixedly installed on the fixed shaft. A mounting frame is also installed on the U-shaped base, and a first telescopic rod is hinged to the mounting frame, with its upper end hinged to the turntable. Although this structure is simple, easy to operate, and provides good turning effect and high efficiency, in actual use, due to the lack of a protective mechanism, when the sand box is turned to the 90°-180° range, the inertial impact force generated by the high-speed turning can easily cause the molding sand to collapse, which may lead to the casting colliding with the inner wall of the sand box due to inertia and causing damage.

[0004] Therefore, there is a need to provide a sand box turning machine that can prevent damage to castings. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents in actual use, such as the lack of a protective mechanism, the inertial impact force generated by the high-speed flipping of the sand box when it is flipped to the 90°-180° range can easily cause the molding sand to collapse, which may lead to the casting colliding with the inner wall of the sand box due to inertia and causing damage, this utility model provides a sand box flipping machine that can prevent damage to castings.

[0006] This utility model provides the following technical solution: a sand box turning machine that can prevent damage to castings, including a base, a mounting frame, a rotating frame, a reduction motor, and a fixing structure. Two mounting frames are slidably mounted on the mounting plate, and a rotating frame is rotatably mounted on the upper part of the mounting frame. A reduction motor is mounted on the right mounting frame, and the output shaft of the reduction motor is connected to the right rotating frame. Two fixing structures are provided on the mounting frame for fixing the mounting frame. The machine also includes a mounting plate, hydraulic buffers, a connecting plate, and a protective plate. The mounting plate is fixedly connected to the middle of the base, and two hydraulic buffers are mounted on the mounting plate. A connecting plate is fixedly connected to the top of the hydraulic buffers, and a protective plate is provided on the connecting plate. The sand box can contact the protective plate.

[0007] Furthermore, the fixing structure includes a fixing block, a clamping frame, an elastic element, and a limiting block. Two fixing blocks are fixedly connected to the top of the mounting frame. A clamping frame is slidably mounted on the fixing blocks. A limiting block is fixedly connected to the lower end of the clamping frame. The limiting block can engage with the mounting frame. An elastic element is sleeved on the clamping frame. Both ends of the elastic element are connected to the fixing block and the limiting block, respectively.

[0008] Furthermore, it also includes limit frames, slide rails, and locking blocks. Two limit frames are installed on the base, and two slide rails are fixedly connected to the limit frames. The mounting bracket is slidably connected to the slide rails, and locking blocks are slidably provided on the slide rails, which can engage with the mounting brackets.

[0009] Furthermore, it also includes a protective pad, with a protective pad adhered to the top of the protective plate.

[0010] Furthermore, it also includes friction blocks, with two friction blocks on the top of the fixed block, which can contact the clamping frame.

[0011] Furthermore, it also includes a placement rack, with placement racks symmetrically arranged on the mounting rack.

[0012] Furthermore, the limiting frame has multiple limiting holes, and the clamping frame can be inserted into the limiting holes.

[0013] Furthermore, the hydraulic buffer has a built-in pressure sensor.

[0014] Compared with the prior art, this utility model provides a sand box turning machine that can prevent casting damage, and has the following beneficial effects: 1. When the sand box is turned to the range of 90°-180°, the bottom of the sand box contacts the protective plate. At this time, the hydraulic buffer is compressed and the internal damping oil circuit will reduce the impact force, thereby avoiding the casting from colliding with the inner wall of the sand box due to inertia and causing damage.

[0015] 2. After unlocking the mounting bracket, slide the mounting bracket laterally along the slide rail and adjust the distance between the two mounting brackets to accommodate sandboxes of different widths. Attached Figure Description

[0021] 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.

[0022] Example 1: A sand box turning machine that can prevent damage to castings, please refer to... Figures 1-4 The system includes a base 1, a mounting bracket 2, a rotating bracket 3, a geared motor 4, and a fixing structure. Two mounting brackets 2 are slidably mounted on the mounting plate 5. A rotating bracket 3 is rotatably mounted on the upper part of the mounting bracket 2. The geared motor 4 is mounted on the right mounting bracket 2, and the output shaft of the geared motor 4 is connected to the right rotating bracket 3. Two fixing structures are provided on the mounting bracket 2 to fix the mounting bracket 2. The fixing structures include fixing blocks 9, clamping brackets 10, elastic elements 11, and limiting blocks 12. Two fixing blocks 9 are fixedly connected to the top of the mounting bracket 2. The clamping brackets 10 are slidably mounted on the fixing blocks 9. The lower end of the clamping brackets 10 is fixedly connected to the limiting blocks 12, which can engage with the mounting bracket 2. The clamping brackets 10 are fitted with elastic elements 11, and both ends of the elastic elements 11 are connected to the fixing blocks 9 and the limiting blocks 12, respectively. The mounting plate 5 is fixedly connected to the middle of the base 1. Two hydraulic buffers 13 are installed on the mounting plate 5. A connecting plate 14 is fixedly connected to the top of the hydraulic buffer 13. A protective plate 15 is provided on the connecting plate 14. The sand box can contact the protective plate 15. A protective pad 16 is glued to the top of the protective plate 15 to prevent the surface of the sand box from directly rubbing or colliding with the protective plate 15 and scratching the surface of the sand box. Two friction blocks 17 are provided on the top of the fixing block 9. The friction blocks 17 can contact the clamping frame 10 to increase the contact surface resistance and prevent the clamping frame 10 from loosening. A placement frame 18 is symmetrically arranged on the mounting frame 2. The placement frame 18 is used to place the casting. The limiting frame 6 has three limiting holes. The clamping frame 10 can be inserted into the limiting holes to lock the position of the mounting frame 2. The hydraulic buffer 13 has a built-in pressure sensor to monitor the impact force in real time and adjust the oil circuit damping inside the hydraulic buffer 13. When the limit is exceeded, the reduction motor is triggered to reduce the speed.

[0023] When this device is needed, place the sand box horizontally on the rotating frame 3, start the reduction motor 4, the output shaft of the reduction motor 4 rotates and drives the rotating frame 3 on the right to rotate, thereby driving the sand box to flip. When the sand box flips to the 90°-180° range, the bottom of the sand box contacts the protective plate 15. At this time, the hydraulic buffer 13 is compressed and its internal damping oil circuit attenuates the impact force, thereby preventing the casting from colliding with the inner wall of the sand box due to inertia and causing damage. After the sand box flips 180°, the casting is separated from the molding sand, and the reduction motor 4 reverses to drive the sand box to reset to the initial position.

[0024] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 2 Two limit frames 6 are installed on the base 1. Two slide rails 7 are fixedly connected to the limit frames 6. The mounting frame 2 is slidably connected to the slide rails 7. A locking block 8 is slidably set on the slide rail 7. The locking block 8 can engage with the mounting frame 2.

[0025] When different sizes of sandboxes are needed, first, pull the locking block 8 outward to disengage it from the mounting bracket 2. Then, pull the clamping bracket 10 upward and compress the elastic element 11 so that the clamping bracket 10 is no longer in contact with the mounting bracket 2, thus releasing the lock on the mounting bracket 2. Slide the mounting bracket 2 laterally along the slide rail 7 to adjust the distance between the two mounting brackets 2 to accommodate sandboxes of different widths. After adjusting the mounting bracket 2 to the appropriate position, release the mounting bracket 2. The elastic element 11 returns to its original state and pushes the limiting bracket 6 downward, so that the clamping bracket 10 inserts into the corresponding limiting hole of the limiting bracket 6, thereby locking the mounting bracket 2. Finally, push the locking block 8 inward to re-engage it with the mounting bracket 2, further locking the mounting bracket 2.

[0026] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
