Description

Technical Field

[0001] The invention relates to the technical field of molding sand separation, in particular to automatic ball casting molding sand separation equipment. Background Art

[0002] In the production of cast balls, after the balls are cast and formed, a large amount of molding sand often adheres tightly to their surface. This molding sand is the key material used to form the mold during the casting process. After the balls cool and set, they lose their function in the mold, but will stick firmly to the surface of the balls. This part of the molding sand must be completely separated from the balls. If not, the balls with molding sand will enter the subsequent processing links, which will affect the processing accuracy. For example, during the grinding and polishing processes, the molding sand may scratch the surface of the balls, resulting in a decline in product quality.

[0003] As a recyclable resource, molding sand will cause serious waste of resources and increase production costs if it is discarded directly without separation. The separation of casting balls and molding sand is an indispensable and extremely critical part of the casting ball production process.

[0004] Existing casting sand separation equipment usually uses a motor to directly drive the screen or vibration mechanism, lacking a buffer design. As a result, the vibration is directly transmitted to the frame and the ground during equipment operation, generating high-decibel noise. In addition, the rigid vibration of the motor and screening mechanism is transmitted to the equipment casing, causing resonance. Especially in closed environments such as metal casting workshops, the noise can reach over 90dB, violating occupational health standards.

[0005] Therefore, we propose an automated ball casting molding sand separation device to solve the problems in the above background. Summary of the Invention

[0028] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0029] Example 1:

[0030] See also Figure 1-6 , the present invention provides a technical solution:

[0031] An automated ball casting sand separation device includes a buffer mechanism 27, wherein a separation mechanism 26 is provided inside the buffer mechanism 27;

[0032] The buffer mechanism 27 is used to reduce the noise of the device. The buffer mechanism 27 includes a base 1. A buffer seat 2 is installed on the surface of the base 1. A buffer rod 3 is arranged inside the buffer seat 2. The surface of the buffer rod 3 is fixedly connected to an extrusion block 4. The surface of the extrusion block 4 close to the end of the buffer seat 2 is installed with a spring 5. The surface of the extrusion block 4 is slidably connected to the inner wall of the buffer seat 2. A mounting frame 6 is installed on the surface of the buffer rod 3. The surface of the mounting frame 6 is fixedly connected to a rotating seat 7. The inner wall of the rotating seat 7 is rotatably connected to a rotating frame 8. A slide rail 10 is provided on the end of the rotating frame 8 away from the rotating seat 7. The surface of the rotating frame 8 is provided with a groove matching the slide rail 10, and the inner wall of the slide rail 10 is slidably connected to the groove.

[0033] Through the above technical solution, the function of the buffer mechanism 27 is to reduce the noise of the device, and this function is achieved through the coordinated operation of various components. Specifically, the base 1 serves as the basic support of the entire buffer mechanism 27, providing an installation platform for the buffer seat 2. The buffer rod 3 inside the buffer seat 2 can move inside it, and the extrusion block 4 fixed on the surface of the buffer rod 3 will slide on the inner wall of the buffer seat 2 as the buffer rod 3 moves. When the extrusion block 4 moves toward one end of the buffer seat 2, it will squeeze the spring 5 installed on its surface. The spring 5 is subjected to force to produce elastic deformation, thereby buffering the movement of the buffer rod 3 and reducing the movement of the device. Vibration during operation; at the same time, the mounting frame 6 installed on the surface of the buffer rod 3 will move with the buffer rod 3, and the rotating seat 7 fixed on the surface of the mounting frame 6 will also move accordingly. The rotating frame 8 connected to the inner wall of the rotating seat 7 is rotatable and the end away from the rotating seat 7 will slide on the slide rail 10. Because the surface of the rotating frame 8 is provided with a groove matching the slide rail 10, the rotating frame 8 can slide stably along the slide rail 10. Such structural coordination further buffers the movement of the mounting frame 6, and the elastic buffer of the spring 5 and the sliding buffer of the rotating frame 8 on the slide rail 10 work together to reduce the noise generated during the operation of the device.

[0034] There are two groups of rotating seats 7, and the inner walls of the two groups of rotating seats 7 are provided with the same rotating frame 8. The surface of the adjacent end of the rotating frame 8 is fixedly connected with a spring 2 9, and the inner wall of the spring 2 9 is slidably connected to the slide rail 10.

[0035] When the cam 10 is in the state of being moved along the track 10, the two movable frames 8 are put into the track 10, so that the cam 10 can move along the track 10, thereby preventing the cam 10 from moving along the track 10.

[0036] Support frames 11 are installed at both ends of the slide rail 10 , and the bottom ends of the support frames 11 are fixedly connected to the base 1 .

[0037] Through the above technical solution, support frames 11 are installed at both ends of the slide rail 10, and the bottom ends of the support frames 11 are fixedly connected to the base 1. This structure provides a solid support for the slide rail 10, so that the slide rail 10 can maintain a stable position during the operation of the device, and will not deviate or shake due to the sliding of the rotating frame 8 and the expansion and contraction of the spring 2 9; at the same time, the support frame 11 is fixedly connected to the base 1, and the force of the slide rail 10 is transferred to the base 1, and the weight and stability of the base 1 are used to further enhance the bearing capacity of the slide rail 10, ensuring that the sliding of the rotating frame 8 on the slide rail 10 is smoother and more stable, providing a reliable foundation for the spring 2 9 to play a buffering role, thereby cooperating with other components of the buffer mechanism to better achieve the function of reducing the noise of the device.

[0038] A mounting frame 22 is installed on the surface of the support frame 11, a motor 23 is installed on the surface of the mounting frame 22, a turntable 24 is installed on the output end of the motor 23, a rotating block 25 is fixedly connected to the surface of the turntable 24, and the rotating block 25 is located at a position deviated from the center of the turntable 24.

[0039] Through the above technical solution, a mounting frame 22 is installed on the surface of the support frame 11, and the mounting frame 22 provides a stable mounting carrier for the motor 23 to ensure that the motor 23 will not easily shake or shift during operation; the motor 23 serves as a power source, and the turntable 24 installed at its output end will rotate under the drive of the motor 23, and the rotating block 25 fixedly connected to the surface of the turntable 24 is located at a position deviated from the center of the turntable 24. When the turntable 24 rotates, the rotating block 25 will perform eccentric motion; this eccentric motion is transmitted to the screening frame 14 through the connecting frame 17 connected to the rotating block 25, thereby driving the screening frame 14 to produce reciprocating shaking, providing the necessary power for the separation mechanism 26 to realize the screening of cast balls and molding sand, so that the screening process can proceed smoothly.

[0040] A limiting frame 12 is installed on the surface of the base 1 , and a molding sand storage basket 13 is provided inside the limiting frame 12 .

[0041] Through the above technical solution, the limiting frame 12 installed on the surface of the base 1 can limit and fix the molding sand storage basket 13 arranged inside it, preventing the molding sand storage basket 13 from shifting or tipping over due to the shaking of the device during the operation of the equipment, thereby ensuring the stability of the storage basket; and the molding sand storage basket 13 is used to collect the molding sand that falls after screening by the separation mechanism 26, so that it can be stored in a centralized manner, which is convenient for subsequent processing or reuse of the molding sand, and avoids the molding sand from scattering on the surface of the base 1 to cause pollution or waste, thereby making the entire separation process more orderly and efficient.

[0042] Example 2:

[0043] See also Figure 1-6 , and combined with Example 1, it is further obtained that the separation mechanism 26 is used to screen the casting balls and molding sand, and the separation mechanism 26 includes a screening frame 14, the surface of the screening frame 14 is fixedly connected to the connecting block 15, and the inner wall of the screening frame 14 is installed with a filter screen 16.

[0044] Through the above technical solution, the core function of the separation mechanism 26 is to screen the casting balls and molding sand. The screening frame 14 contained therein serves as the main bearing structure for the screening operation, providing space for the separation of the casting balls and molding sand; the connecting block 15 fixedly connected to the surface of the screening frame 14 plays the role of connecting the screening frame 14 and the mounting frame 6, so that the screening frame 14 can move accordingly with the operation of the buffer mechanism under the drive of the mounting frame 6, thereby ensuring the stable progress of the screening process; and the filter screen 16 installed on the inner wall of the screening frame 14 is a key component for realizing screening. When the screening frame 14 moves, the casting balls and molding sand move inside it. Since the filter screen 16 has a specific aperture, the molding sand can be separated through the filter screen 16, while the casting balls cannot pass through the filter screen 16 due to their large volume and are retained, thereby preliminarily realizing the separation of casting balls and molding sand.

[0045] The surface of the screening frame 14 is hingedly connected with a screening frame 20 , and the inner wall of the screening frame 20 is installed with a second filter screen 21 , which is used to screen out molding sand.

[0046] Through the above technical solution, the surface of the screening frame 14 is hingedly connected to the screening frame 20. This hinged connection allows the screening frame 20 to flexibly rotate around the connection, which is convenient for pouring out the retained cast balls after the screening is completed; the filter screen 21 installed on the inner wall of the screening frame 20 cooperates with the filter screen 16 to further separate the cast balls and molding sand. Since the filter screen 21 is used to screen out the molding sand, when the screening frame 14 drives the screening frame 20 to move together, the fine molding sand that is not completely screened out by the filter screen 16 will be screened out through the filter screen 21, while the cast balls will be left in the screening frame 20. This not only enhances the separation effect of the molding sand, but also can play the role of receiving and storing the cast balls through the screening frame 20.

[0047] The inner wall of the screening frame 14 is provided with a groove, the inner wall of the groove is provided with a spring 3 18 , and a clamping block 19 is provided at one end of the spring 3 18 away from the groove.

[0048] Through the above technical solution, the groove provided on the inner wall of the screening frame 14 provides installation space for the spring three 18 and the block 19. The spring three 18 installed on the inner wall of the groove has a block 19 installed on the end away from the groove. In the natural state, the spring three 18 will push the block 19 out of the groove. When the screening frame 20 and the screening frame 14 are in a closed state, the block 19 can be stuck into the corresponding groove on the surface of the screening frame 20, thereby firmly fixing the screening frame 20 on the screening frame 14, preventing the screening frame 20 from accidentally opening during the activity of the screening frame 14, and ensuring the normal progress of the screening work; and when it is necessary to dump the cast balls, pressing the block 19 will compress the spring three 18, causing the block 19 to retract into the groove, thereby releasing the fixation of the screening frame 20 and facilitating the rotation of the screening frame 20 around the hinge.

[0049] The surface of the screening frame 20 is provided with a card slot that matches the card block 19. The card slot is used to limit the screening frame 20. The inner wall of the screening frame 20 is provided with a slope.

[0050] Through the above technical solution, a slot matching the block 19 is provided on the surface of the screening frame 20. When the screening frame 20 and the screening frame 14 are in a closed state, the block 19 will be stuck in the slot under the thrust of the spring three 18. The slot effectively limits the screening frame 20 by cooperating with the block 19, further enhancing the fixing effect of the screening frame 20 on the screening frame 14, ensuring that the screening frame 20 will not loosen or shift during the shaking process of the screening frame 14; and the inner wall of the screening frame 20 is provided with a slope. When the cast balls after screening need to be dumped, when the block 19 is disengaged from the slot, the screening frame 20 is rotated around the hinge, and the cast balls will automatically slide down along the slope of the inner wall under the action of their own gravity, and the dumping operation of the cast balls can be completed conveniently and quickly, thereby improving the convenience of using the equipment.

[0051] A connecting frame 17 is provided on the surface of the screening frame 14. The surface of the connecting frame 17 is fixedly connected to the rotating block 25. The surface of the connecting block 15 is rotatably connected to the inner wall of the mounting frame 6.

[0052] Through the above technical solution, a connecting frame 17 is provided on the surface of the screening frame 14, and its surface is fixedly connected to the rotating block 25. When the motor 23 drives the turntable 24 to rotate, the rotating block 25 deviating from the center of the circle performs eccentric motion, and this motion is transmitted to the screening frame 14 through the connecting frame 17, thereby driving the screening frame 14 to shake, providing power for the screening of cast balls and molding sand; and the surface of the connecting block 15 is rotatably connected to the inner wall of the mounting frame 6, so that the screening frame 14 can flexibly move with the connecting block 15 as the fulcrum during the shaking process. At the same time, the mounting frame 6 supports the screening frame 14 through the connecting block 15, and cooperates with the buffering effect of the buffer mechanism 27 to ensure that the screening frame 14 shakes and screens in a stable state.

[0053] Working principle: When the equipment is started, the motor 23 starts to run, driving the turntable 24 connected to it to rotate. Since the rotating block 25 is fixed at a position deviated from the center of the turntable 24, the turntable 24 will make eccentric movement with the rotating block 25 when it rotates, and the rotating block 25 is connected to the screening frame 14 through the connecting frame 17. In this way, the screening frame 14 will rock under the drive of the rotating block 25; when the screening frame 14 rocks, the connecting block 15 on its surface will drive the mounting frame 6 to move together, and the mounting frame 6 is connected to the buffer rod 3, so the buffer rod 3 will move up and down in the buffer seat 2, and the extrusion block 4 on the buffer rod 3 will squeeze the spring 5, and the spring 5 is compressed to generate elastic force, which plays the first buffering role on the rocking of the mounting frame 6; at the same time, the movement of the mounting frame 6 will drive the rotating seat 7 to move, and the rotating seat 7 The rotating frame 8 will slide along the slide rail 10, and the adjacent ends of the two sets of rotating frames 8 will approach each other and squeeze the spring 2 9. The elastic force generated by the spring 2 9 forms a second buffer. Through these two buffers, the shaking of the entire device can be effectively reduced, thereby reducing the noise during operation; in the process of shaking of the screening frame 14, the casting balls and molding sand placed inside it will move accordingly, and the molding sand will be screened out through the filter screen 16 and the filter screen 21 and fall into the molding sand storage basket 13 in the lower limit frame 12, while the casting balls will be trapped in the screening frame 20; when the separated casting balls need to be taken out, the card block 19 is pressed, and the card block 19 will compress the spring 3 18 and withdraw from the card slot on the surface of the screening frame 20. At this time, the screening frame 20 can be rotated along the hinge with the screening frame 14, and the casting balls can be dumped out by using the slope of the inner wall of the screening frame 20.

[0054] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
