Technical Field
[0001] This invention belongs to the field of casting technology, and specifically relates to an inertial vibration sand removal machine for casting. Background Technology
[0002] Vibratory sand removal machines are key equipment in casting production for separating molding sand from castings. They achieve efficient sand removal through the combined effects of vibration, impact, and inertia, and are widely used in the post-processing stages of casting production lines.
[0003] When existing vibratory sand removal machines are in use, the casting is vibrated above the support frame of the sand removal machine, so that the casting can be separated from the molding sand. However, when the casting vibrates on the support frame, it tends to be horizontal. The molding sand on the top cannot be separated from the casting as fully as the molding sand at the bottom. In addition, some castings have holes on the side, and the molding sand in the holes cannot be separated from the casting fully either.
[0004] Therefore, it is necessary to invent an inertial vibration sand removal machine for casting to solve the above problems. Summary of the Invention
[0005] To address the aforementioned problems, this invention provides an inertial vibration sand removal machine for casting, thereby solving the issues raised in the background section.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an inertial vibration shakeout machine for casting, comprising: A sand removal machine is used for vibratory sand removal. Support plates are equidistantly arranged inside the sand removal machine to support the castings; A support base is connected to the bottom of the support plate; A cylinder, with one end connected to the bottom of the support base and the other end connected to the bottom wall of the sand removal machine, is used to push the support base upward; A flipping assembly, disposed on the support plate, is used to flip the casting. The flipping assembly includes: An arc surface is provided on the top of the support plate; Inclined surfaces are symmetrically arranged on the sides of the support plate; Adsorption elements are symmetrically arranged inside the support plate to adsorb and fix the casting.
[0007] Furthermore, the adsorption element includes: The first electromagnet is symmetrically arranged inside the support plate; The second electromagnet is symmetrically arranged on the support plate and is located above the first electromagnet.
[0008] Furthermore, the top of the support base is provided with a boss, and the distance between the edge of the boss and the center line of the support plate is greater than the distance between the edge of the second electromagnet and the center line of the support plate.
[0009] Furthermore, the second electromagnet is cylindrical, and a mounting plate is fixedly installed on one end of the support plate. One end of the second electromagnet is rotatably mounted on the mounting plate, and a rotating component for driving its rotation is provided on one end of the second electromagnet.
[0010] Furthermore, the rotating assembly includes: A shaft is fixedly connected to the middle of the end of the second electromagnet away from the mounting plate; The gear is fixedly sleeved on the shaft; Teeth are provided on one side of the gear and mesh with the gear.
[0011] Furthermore, a limiting plate is fixedly installed on one side of the inner wall of the sand removal machine, and a limiting groove is formed on the limiting plate. A limiting block matching the limiting groove is fixedly installed at one end of the support plate.
[0012] Furthermore, the gaps between adjacent support plates and between adjacent support seats allow molding sand to fall through, while the casting cannot fall through the gaps.
[0013] Furthermore, the inclination angle of the inclined plane is degrees, and the magnetic force of the first electromagnet is sufficient to penetrate the support plate to attract and fix the casting.
[0014] Furthermore, the multiple support seats can be raised and lowered sequentially under the push of the cylinder.
[0015] The technical effects and advantages of this invention are as follows: 1. This invention can flip the casting, so that the molding sand on the top of the casting can be vibrated and separated from the casting, and can keep the casting with its side facing down for a period of time, thereby separating the molding sand in the side hole of the casting from the casting and improving the separation effect between the casting and the molding sand. 2. This invention can guide the casting to face down when flipping small and light castings, ensuring that such castings can be flipped smoothly in the future. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0018] This invention provides an inertial vibration shakeout machine for casting, such as... Figures 1 to 6 As shown, it includes: a sand removal machine 1, a support plate 2, a support base 3, a cylinder 4, and a flipping assembly; The sand removal machine 1 is used for vibratory sand removal. The sand removal machine 1 is an inertial vibratory sand removal machine for casting in the prior art. The support plates 2 are equidistantly arranged inside the sand removal machine 1 to support the castings. The support base 3 is fixedly connected to the bottom of the support plate 2. One end of the cylinder 4 is fixedly connected to the bottom of the support base 3, and the other end is fixedly connected to the bottom wall of the sand removal machine 1 to push the support base 3 to rise. The flipping assembly is arranged on the support plate 2 to flip the castings. The flipping assembly includes: curved surface 8, inclined surface 9, and suction element; The arc surface 8 is set on the top of the support plate 2, the inclined surface 9 is symmetrically set on the side of the support plate 2, and the adsorption components are symmetrically set inside the support plate 2 for adsorption and fixation of the casting.
[0019] When in use, the casting is placed on the support plate 2 and vibrated by the sand removal machine 1 to separate the casting from the covering molding sand. Since the casting tends to be horizontal when the support plate 2 vibrates, the molding sand covering the top and side holes of the casting cannot be removed, which affects the separation effect. Therefore, during the vibration process, the cylinder 4 is activated, causing it to rise along with the connected support base 3 and support plate 2. The support plate 2 rises, with the casting resting on one side of its top. The casting is then held in place by the suction device. The casting is held in place on the support plate 2 near the arc surface 8. As the support plate 2 continues to rise, the other side of the casting deflects downwards under the influence of gravity, eventually being held in place by the suction device at the inclined surface 9, so that the side of the casting faces downwards. Then, the cylinder 4 stops moving, and with the vibration of the sand removal machine 1, the casting shakes, dislodging the molding sand from the side holes. Finally, the suction device releases its hold on the casting. When the casting is adsorbed onto the inclined plane 9, its originally upward side is now angled downward. Therefore, when the casting falls, the originally upward side of the casting will contact the top of the support plate 2, thus flipping the casting. Then, the cylinder 4 drives the support base 3 and the support plate 2 to descend and reset. After a 30-second interval, the adjacent cylinder 4 repeats the above operation, causing the adjacent support plate 2 to repeat the above operation. Subsequently, multiple support plates 2 rise and fall in sequence, enabling the casting to be flipped and the casting to remain facing downward for a period of time. This, combined with vibration, allows for the separation of molding sand from the top and sides of the casting, improving the separation effect.
[0020] like Figures 2 to 6 As shown, the adsorption component includes: a first electromagnet 10 and a second electromagnet 11; The first electromagnet 10 is symmetrically arranged inside the support plate 2, and the second electromagnet 11 is symmetrically arranged on the support plate 2, and is located above the first electromagnet 10.
[0021] The first electromagnet 10 and the second electromagnet 11 are energized to make them magnetic, so that they can attract the casting. One side of the casting is first attracted to the second electromagnet 11. As the support plate 2 is raised, the casting remains attracted to the second electromagnet 11 under the action of gravity. The other side of the casting deflects downward under the action of gravity. During this process, the casting slides relative to the second electromagnet 11. Finally, the casting is attracted and fixed by the first electromagnet 10.
[0022] like Figure 4 As shown, the top of the support base 3 is provided with a boss 15, and the distance between the edge of the boss 15 and the center line of the support plate 2 is greater than the distance between the edge of the second electromagnet 11 and the center line of the support plate 2.
[0023] The boss 15 can move one side of the casting when it falls after the casting is no longer attached to the adsorption component, so that the casting can be flipped over.
[0024] like Figures 2 to 6 As shown, the second electromagnet 11 is cylindrical, and a mounting plate 12 is fixedly installed on one end of the support plate 2. One end of the second electromagnet 11 is rotatably mounted on the mounting plate 12, and a rotating component for driving its rotation is provided on one end of the second electromagnet 11.
[0025] Because some castings are small in size and light in weight, after being attracted to the second electromagnet 11, as the support plate 2 rises, the casting cannot rely on its own weight to deflect one side downwards. When the casting rises, it remains relatively stationary with the second electromagnet 11. After the second electromagnet 11 is de-energized, the casting falls. Although one side of the casting can abut against the boss 15, due to the height of the fall, it still cannot be flipped over. Moreover, after the second electromagnet 11 rises to a stop, the side of the casting still cannot face down, so the molding sand in the side hole cannot be cleaned.
[0026] Therefore, when such small and lightweight castings are attracted and fixed by the second electromagnet 11, as the support plate 2 rises, the rotating component drives the second electromagnet 11 to rotate, causing the casting to rotate downwards. Eventually, the casting is attracted and fixed on the inclined surface 9 by the first electromagnet 10, so that the side of the casting that was originally facing upwards is now inclined downwards, ensuring that the casting can be flipped smoothly in the future, and the side of the casting can remain in a downward position for a period of time, so that the molding sand in the side hole can be separated.
[0027] like Figure 3 and Figure 6 As shown, the rotating assembly includes: a shaft, a gear 13, and teeth 14; The shaft is fixedly connected to the middle of the end of the second electromagnet 11 away from the mounting plate 12. The gear 13 is fixedly sleeved on the shaft. The teeth 14 are set on one side of the gear 13 and mesh with the gear 13. A limit plate 5 is fixedly installed on the inner wall of one side of the sand removal machine 1. A limit groove 6 is opened on the limit plate 5. A limit block 7 matching the limit groove 6 is fixedly installed on one end of the support plate 2. Specifically, a long groove is opened on the limit plate 5, and the teeth 14 are equidistantly arranged on the inner wall of one side of the long groove.
[0028] The cooperation between the limiting block 7 and the limiting groove 6 ensures that the support plate 2 will not shift, thus maintaining the gap between adjacent support plates 2. The support plate 2, along with the mounting plate 12, the second electromagnet 11, the shaft, and the gear 13, rises. The gear 13 moves along the teeth 14, causing the shaft and the second electromagnet 11 to rotate, thus driving the second electromagnet 11 to rotate.
[0029] like Figure 1 As shown, the gaps between adjacent support plates 2 and between adjacent support seats 3 allow molding sand to fall through, while castings cannot fall through the gaps.
[0030] This ensures that the casting will not fall through the gap.
[0031] like Figure 4As shown, the inclination angle of the inclined plane 9 is 30 degrees, and the magnetic force of the first electromagnet 10 is sufficient to penetrate the support plate 2 to attract and fix the casting.
[0032] This causes the casting, which was attracted and fixed on the inclined plane 9 by the first electromagnet 10, to be able to tilt downwards from the surface that was originally located at the top.
[0033] like Figure 2 As shown, multiple support bases 3 can be raised and lowered sequentially under the push of cylinder 4.
[0034] The sequential lifting and lowering is controlled by a PLC controller (not shown in the figure), which is located on the ground.
[0035] The aforementioned sand removal machine is designed for castings made of materials that can be magnetically attracted.
[0036] Cylinder 4 is a heavy-duty ISO standard anti-vibration cylinder.
[0037] Working principle: When in use, the casting is placed on the support plate 2 and vibrated by the sand removal machine 1 to separate the casting from the covering molding sand. Since the casting tends to be horizontal when the support plate 2 vibrates, the molding sand covering the top and side holes of the casting cannot be removed, which affects the separation effect. Therefore, during the vibration process, the cylinder 4 is activated, causing it to lift the connected support base 3 and support plate 2. The support plate 2, with the casting resting on one side of its top, rises, energizing the first electromagnet 10 and the second electromagnet 11 to make them magnetic, thus attracting the casting. One side of the casting is initially attracted to the second electromagnet 11. As the support plate 2 rises, the casting remains attracted to the second electromagnet 11 under the action of gravity, while the other side of the casting deflects downwards under the action of gravity. During this process, the casting slides relative to the second electromagnet 11. Finally, the casting is attracted and fixed on the inclined plane 9 by the first electromagnet 10, so that the side of the casting faces downwards. Then, the cylinder 4 stops moving, and with the vibration of the sand removal machine 1, the casting shakes, causing the side to... The molding sand inside the hole is shaken off, and then the first electromagnet 10 and the second electromagnet 11 are de-energized to cancel the adsorption and fixation of the casting. Since the casting was adsorbed on the inclined surface 9, its original upward side is now inclined downward. Therefore, when the casting falls, the original upward side of the casting will contact the top of the support plate 2, realizing the flipping of the casting. Then, the cylinder 4 drives the support base 3 and the support plate 2 to descend and reset. After a 30-second interval, the adjacent cylinder 4 repeats the above operation, so that the adjacent support plate 2 repeats the above operation. Subsequently, multiple support plates 2 are raised and lowered in sequence, so that the casting can be flipped and the side of the casting can be kept facing down for a period of time. With the vibration, the molding sand on the top and side of the casting can be separated, improving the separation effect. Because some castings are small in size and light in weight, after these castings are attracted to the second electromagnet 11, as the support plate 2 rises, the castings cannot rely on their own weight to deflect one side downwards. When the castings rise, they remain relatively stationary with the second electromagnet 11. After the second electromagnet 11 is de-energized, the castings fall. Although one side of the casting can abut against the boss 15, due to the height of the fall, it is still impossible to flip the castings over. Furthermore, after the second electromagnet 11 rises to a stop, the side of the castings still cannot face down, so the molding sand in the side holes cannot be cleaned. Therefore, when such small and lightweight castings are attracted and fixed by the second electromagnet 11, as the support plate 2 rises, the support plate 2, along with the mounting plate 12, the second electromagnet 11, the shaft, and the gear 13, rises. The gear 13 moves along the teeth 14, causing the shaft and the second electromagnet 11 to rotate, causing the casting to rotate downwards. Ultimately, the casting is attracted and fixed on the inclined surface 9 by the first electromagnet 10, so that the side of the casting that was originally facing upwards is now inclined downwards, ensuring that the casting can be flipped smoothly in the future, and the side of the casting can remain in a downward state for a period of time, so that the molding sand in the side hole can be separated.
[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
