Description

Technical Field

[0001] This utility model belongs to the technical field of sand removal machines, specifically relating to a sand removal machine for casting production and processing. Background Technology

[0002] A sand removal machine is a commonly used piece of equipment in casting, primarily used to separate molding sand from the casting. It utilizes vibration and impact, employing a mechanical device to generate intense vibration or impact force in the mold, causing the molding sand to detach from the casting under the influence of gravity and centrifugal force. This achieves the effect of cleaning the surface of the casting and improving its quality. Simultaneously, the vibration moves the casting towards the discharge port, where the separated molding sand is discharged from the bottom.

[0003] While existing sand removal machines can separate molding sand from castings, some of the separated molding sand remains in clumps. These clumps need to be broken up after collection before they can be reused, which is cumbersome and inconvenient. Furthermore, when the casting is pressed directly onto the screen plate, the molding sand at the bottom is squeezed between the casting and the screen plate, making it more difficult for the sand clumps in these areas to be broken up by vibration and discharged from the gaps, resulting in incomplete sand removal. To address this, we propose a casting sand removal machine for casting production and processing. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a casting sand removal machine for casting production and processing, so as to solve the problem mentioned in the background art that although the existing sand removal machine can separate molding sand from castings, some of the separated molding sand is still in clumps, which need to be broken up after collection before it can be reused. This is cumbersome to operate and inconvenient to use. Moreover, when the casting is directly pressed on the screen plate, the molding sand at the bottom will be squeezed between the casting and the screen plate, making it more difficult for the sand blocks in these areas to be broken up by vibration and discharged from the gap, resulting in incomplete sand removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a casting sand removal machine for casting production and processing, comprising a shock-absorbing support, a sand removal machine body fixedly connected to the top of the shock-absorbing support, multiple sets of screen plates installed on the top of the sand removal machine body, partitions fixedly connected between the multiple sets of screen plates, a sand outlet opening at the bottom of the sand removal machine body, two sets of motors fixedly connected to the surface of the sand outlet, crushing rollers fixedly connected to the output ends of the two sets of motors, sliders fixedly connected to both sides of the sand outlet, a collection box slidably connected to the bottom of the sand outlet, handles fixedly connected to the front and rear ends of the collection box, four sets of spring buckles symmetrically installed at the front and rear ends of the sand outlet and the collection box, two sets of sliding grooves opening on the surface of the collection box, a slot opening on the top of the collection box, and a screen slidably connected inside the slot.

[0006] Preferably, the top of the partition is rounded, and a rubber pad layer is fitted onto the surface of the partition.

[0007] Preferably, the motor is electrically connected to an external power source, and the two sets of motors rotate in opposite directions.

[0008] Preferably, the two ends of the two sets of crushing rollers respectively penetrate the surface of the sand outlet, and the two sets of crushing rollers are arranged symmetrically.

[0009] Preferably, the slider has a T-shaped cross-section, and the groove matches the slider.

[0010] Preferably, the shock-absorbing support is fixedly connected to the ground by bolts, and the collection box does not contact the ground.

[0011] Preferably, the slots are located at the front and rear ends of the top of the collection box, the front and rear ends of the screen are engaged in the slots, and the top of the screen is in contact with the bottom of the sand outlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This casting sand removal machine for casting production and processing is equipped with a sand outlet and a collection box. The sand removal machine body separates the castings and molding sand. The separated molding sand passes through the screen plate and enters the sand outlet. The motor drives the crushing rollers to rotate, causing two sets of crushing rollers to squeeze the molding sand, breaking up the still clumped molding sand after separation. Then, the molding sand is screened through the screen on the top of the collection box. At the same time, the collection box vibrates with the sand removal machine body, which reduces the possibility of screen clogging to a certain extent. The collection box is slidably installed at the bottom of the sand outlet by the cooperation of the slider and the chute, and is fixed by spring buckles, making the installation and disassembly of the collection box simple and convenient. It is convenient to remove the collection box for reuse of molding sand and replacement of screen. It can squeeze and break up the clumped molding sand, making it convenient to directly recycle the separated molding sand. It is convenient to use.

[0014] 2. This casting sand removal machine for casting production and processing is equipped with a screen plate and a partition plate. The casting is placed in the sand removal machine body, and the partition plate prevents the bottom of the casting from contacting the screen plate, leaving a certain gap between them. When the casting and molding sand are separated by vibration by the sand removal machine body, the broken sand particles can fall more freely through the gap under the action of vibration and gravity, effectively avoiding the phenomenon of sand stuck at the bottom and significantly improving the cleaning quality of the bottom of the casting. A rubber pad layer is set on the surface of the partition plate, which effectively reduces the friction between the casting, sand particles and screen plate during the violent vibration, effectively protecting the casting and increasing the service life of the screen plate.

[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] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A casting sand removal machine for casting production and processing includes a shock-absorbing support 1. A sand removal machine body 2 is fixedly connected to the top of the shock-absorbing support 1. Multiple sets of screen plates 21 are installed on the top of the sand removal machine body 2, and partitions 22 are fixedly connected between the multiple sets of screen plates 21. A sand outlet 3 is opened at the bottom of the sand removal machine body 2. Two sets of motors 31 are fixedly connected to the surface of the sand outlet 3. Crushing rollers 32 are fixedly connected to the output ends of the two sets of motors 31. Sliding blocks 33 are fixedly connected to both sides of the sand outlet 3. A collection box 4 is slidably connected to the bottom of the sand outlet 3, and handles 41 are fixedly connected to both the front and rear ends of the collection box 4. Four sets of spring latches 42 are symmetrically installed at the front and rear ends of the sand outlet 3 and the collection box 4. Two sets of sliding grooves 43 are opened on the surface of the collection box 4, and a slot 44 is opened on the top of the collection box 4. A screen 45 is slidably connected inside the slot 44. With the sand outlet 3 and the collection box 4 set up, the casting and molding sand are separated by the sand removal machine body 2. The separated molding sand passes through the screen plate 21 and enters the sand outlet 3. The motor 31 drives the crushing roller 32 to rotate, so that the two sets of crushing rollers 32 squeeze the molding sand, breaking up the molding sand that is still in a clump after separation. Then it passes through the screen 45 on the top of the collection box 4. The molding sand is screened in five stages. Simultaneously, the collection box 4 vibrates with the main body 2 of the sand removal machine, reducing the possibility of screen 45 clogging. The collection box 4 is slidably installed at the bottom of the sand outlet 3 via the cooperation of the slider 33 and the chute 43, and is fixed by spring buckles 42. This makes the installation and disassembly of the collection box 4 simple and convenient, facilitating the removal of the collection box 4 for the reuse of molding sand and the replacement of the screen 45. It can squeeze and break up clumps of molding sand, facilitating the direct recycling of the separated molding sand. It is convenient to use. A screen plate 21 and a partition plate 22 are installed to separate the castings... Placed inside the sand removal machine body 2, the bottom of the casting is kept away from the screen plate 21 by the partition 22, leaving a certain gap between them. When the casting and molding sand are separated by vibration by the sand removal machine body 2, the broken sand particles can fall more freely through the gap under the action of vibration and gravity, effectively avoiding the phenomenon of sand stuck at the bottom and significantly improving the cleaning quality of the bottom of the casting. A rubber pad layer is set on the surface of the partition 22, which effectively reduces the friction between the casting, sand particles and screen plate 21 during the violent vibration, effectively protecting the casting and increasing the service life of screen plate 21.

[0024] Furthermore, the top of the partition 22 is rounded, and the surface of the partition 22 is fitted with a rubber pad layer, which effectively reduces the friction between the casting, sand particles and the screen plate 21 during violent vibration, and effectively protects the casting. The rounded corner can reduce the contact area between the bottom of the casting and the partition 22, and reduce the possibility of sand getting stuck at the bottom of the casting.

[0025] Furthermore, the motor 31 is electrically connected to an external power source, and the two sets of motors 31 rotate in opposite directions. The external power source supplies power to the motors 31 and controls the two sets of motors 31.

[0026] Furthermore, the two ends of the two sets of crushing rollers 32 penetrate the surface of the sand outlet 3 respectively. The two sets of crushing rollers 32 are symmetrically arranged and rotate in opposite directions to squeeze the molding sand and break up the molding sand that is still in a clump after separation.

[0027] Furthermore, the cross-section of the slider 33 is T-shaped, and the groove 43 matches the slider 33. The collection box 4 is slidably installed at the bottom of the sand outlet 3 through the cooperation of the slider 33 and the groove 43. The groove 43 and the slider 33 limit the collection box 4, so that the collection box 4 can only move along the direction of the groove 43.

[0028] Furthermore, the shock-absorbing support 1 is fixedly connected to the ground by bolts, and the collection box 4 does not contact the ground. The collection box 4 vibrates with the sand removal machine body 2 to prevent the collection box 4 from interfering with the ground when it shakes.

[0029] Furthermore, the slots 44 are located at the front and rear ends of the top of the collection box 4. The front and rear ends of the screen 45 are engaged in the slots 44. The top of the screen 45 is in contact with the bottom of the sand outlet 3. After the collection box 4 is fixed to the bottom of the sand outlet 3 by the spring buckle 42, the top of the screen 45 and the bottom of the sand outlet 3 are pressed against each other, which limits the vertical movement of the screen 45. At the same time, the slots 44 restrict the horizontal movement of the screen 45, thereby fixing the screen 45 in the slots 44.

[0030] Working principle: The casting is placed inside the sand removal machine body 2. A partition 22 prevents the bottom of the casting from contacting the sieve plate 21, leaving a gap between them. When the casting and molding sand are separated by vibration in the sand removal machine body 2, the broken sand particles can fall more freely through the gap under the action of vibration and gravity, effectively avoiding sand jamming at the bottom. The sand removal machine body 2 separates the casting and molding sand. The separated molding sand passes through the sieve plate 21 and enters the sand outlet 3. The motor 31 drives the crushing roller 32 to rotate, causing the two sets of powder... The crushing roller 32 squeezes the molding sand, breaking up the clumps of molding sand after separation. The sand is then screened through the screen 45 on the top of the collection box 4. The collection box 4 vibrates with the sand removal machine body 2, which reduces the possibility of the screen 45 being blocked. The collection box 4 is slidably installed at the bottom of the sand outlet 3 through the cooperation of the slider 33 and the chute 43, and is fixed by the spring buckle 42. This makes the installation and disassembly of the collection box 4 simple and convenient, and makes it easy to remove the collection box 4 for reuse of molding sand and replacement of the screen 45.
