Abstract
Description
Technical Field
[0001] This invention relates to the field of casting equipment technology, and more specifically, to a casting equipment using polyhedral grinding media. Background Technology
[0002] In industries such as mining, building materials processing, and chemical production, polyhedral grinding media are widely used in equipment such as ball mills and stirred mills for material crushing and fine grinding due to their advantages such as large contact area, high grinding efficiency, and uniform wear. As downstream industries continue to demand higher precision in material grinding and increased production efficiency, the market demand for polyhedral grinding media continues to grow, placing higher demands on the automation level, molding quality, and production efficiency of its casting production.
[0003] Currently, casting equipment using polyhedral grinding media is mainly divided into two categories: one is traditional manual casting equipment, which requires manual handling of the mold to the casting station, manual alignment with the pouring gate, and pouring of molten metal. After casting, the mold is manually removed for cooling. This method is not only labor-intensive and inefficient, but also suffers from poor precision when manually aligning the mold with the pouring gate, easily leading to molten metal splashing and waste. Furthermore, it lacks a rotating auxiliary filling structure for the mold, resulting in slow flow of molten metal in the cavity, which easily leads to defects such as material shortage, porosity, and loose structure. The product qualification rate is only 70%-80%. The other category is semi-automatic casting equipment, which achieves partial mechanization of mold movement. However, the coordination between the mold and the casting mechanism is poor. Before casting, additional time is needed to adjust the mold position to align with the pouring gate. During the casting process, the mold remains stationary, resulting in insufficient molten metal filling and requiring manual assistance to address material shortages at the cavity edges.
[0004] With rising labor costs and the advancement of intelligent transformation in manufacturing, the problems of low efficiency, high reliance on manual labor, and unstable product quality of traditional casting equipment are becoming increasingly prominent, making it unable to meet the demands of large-scale, high-precision production. Therefore, there is an urgent need for a multi-faceted grinding media casting equipment that can achieve precise coordination between molds and casting mechanisms, efficient molten metal filling, and a high degree of automation, in order to improve production efficiency, reduce labor costs, increase product qualification rates, and meet the actual needs of industry development. Summary of the Invention
[0005] The present invention aims to solve the problem of poor coordination between mold movement and casting and low casting efficiency in the existing polyhedral grinding media casting process.
[0006] To address the aforementioned problems, this invention provides a multi-faceted grinding media casting device, comprising a base, a groove on the upper surface of the base, a movable plate slidably disposed within the groove, a turntable rotatably disposed within the movable plate, a lower mold and an upper mold disposed on the upper surface of the turntable, a connecting rod fixedly mounted on the lower surface of the upper mold, a connecting hole for cooperating with the connecting rod on the upper surface of the lower mold, and a casting port disposed on the upper surface of the upper mold, and a driving assembly disposed at the bottom of the movable plate for driving the turntable to rotate, and further comprising: a limiting mechanism disposed between the lower mold and the turntable for limiting the position of the lower mold so that the lower mold rotates together with the turntable; a casting mechanism disposed above the base for guiding molten metal to be cast between the lower mold and the upper mold; and a moving mechanism disposed on the base for driving the movable plate to move in the groove, so that the movable plate moves in and out of the casting mechanism.
[0007] The polyhedral grinding media casting equipment provided by this invention has, but is not limited to, the following beneficial effects compared with the prior art: To address the issues of poor coordination between mold movement and casting, resulting in low casting efficiency in existing polyhedral grinding media casting processes, this equipment first hoists the lower mold onto the turntable during casting. A limiting mechanism restricts the lower mold's position, allowing it to rotate with the turntable. Then, the upper mold is hoisted above the lower mold, and the mating rod is inserted into the mating hole to close the mold. A moving mechanism then moves the movable plate along a chute, transporting the mold below the casting mechanism. The casting mechanism guides the molten metal into the mold. During the casting process, the drive assembly can also... The rotating plate rotates the turntable, causing the mold to rotate as well. During the rotation, the molten metal expands rapidly from the center outwards into the polyhedral cavity under centrifugal force, resulting in better casting. After casting, the moving mechanism moves the movable plate out of the casting area. Once the casting has cooled to room temperature, it is lifted off the upper mold and can be removed. Repeating the above steps enables batch production. This equipment increases the molten metal filling speed by 40% through mold rotation, effectively avoiding defects such as insufficient material and porosity. Furthermore, the coordinated operation of each mechanism results in a high degree of automation, requiring no manual intervention and providing better performance.

The adjustment block is in the shape of an inverted trapezoid and is used to cause the casting pipe to be inserted into the casting port when the push rod is disengaged from the adjustment block. A baffle is also fixedly installed on the outer side of the telescopic rod to limit the downward movement of the lifting plate.
[0012] Furthermore, it also includes a locking mechanism, which is located above the turntable and is used to lock the upper and lower molds before casting.
[0013] Furthermore, the locking mechanism includes locking plates symmetrically installed on the lower surface of the upper mold, and the locking plates are L-shaped.

[0027] See Figures 1-6 An embodiment of the present invention provides a multi-faceted grinding media casting device, comprising a base 1, a groove 11 on the upper surface of the base 1, a movable plate 2 slidably disposed in the groove 11, a turntable 21 rotatably disposed in the movable plate 2, a lower mold 22 and an upper mold 23 disposed on the upper surface of the turntable 21, a connecting rod 25 fixedly mounted on the lower surface of the upper mold 23, a connecting hole for cooperating with the connecting rod 25 on the upper surface of the lower mold 22, a casting port 24 disposed on the upper surface of the upper mold 23, and a drive mechanism at the bottom of the movable plate 2. The moving component 8, used to drive the turntable 21 to rotate, also includes: a limiting mechanism 3, which is disposed between the lower mold 22 and the turntable 21, used to limit the position of the lower mold 22 so that the lower mold 22 rotates together with the turntable 21; a casting mechanism 4, which is disposed above the base 1, used to guide the molten metal liquid to be cast between the lower mold 22 and the upper mold 23; and a moving mechanism 5, which is disposed on the base 1, used to drive the movable plate 2 to move in the slide 11, so that the movable plate 2 moves in and out of the casting mechanism 4.
[0028] In this embodiment, addressing the problem of poor coordination between mold movement and casting, resulting in low casting efficiency in existing polyhedral grinding media casting processes, this equipment first hoists the lower mold 22 onto the turntable 21 during casting. The position of the lower mold 22 is limited by the limiting mechanism 3, allowing it to rotate with the turntable 21. Then, the upper mold 23 is hoisted above the lower mold 22, and the connecting rod 25 is inserted into the connecting hole to close the mold. Next, the moving mechanism 5 drives the movable plate 2 to move along the slide 11, transferring the mold to below the casting mechanism 4. The casting mechanism 4 then guides the molten metal into the mold. The casting process... In addition, the drive component 8 can drive the turntable 21 to rotate in the movable plate 2, so that the mold rotates together. During the rotation, the molten metal expands rapidly from the center to the periphery into the polyhedral cavity under the action of centrifugal force, resulting in a better casting effect. After casting is completed, the moving mechanism 5 moves the movable plate 2 out of the casting area. After the casting cools to room temperature, it is lifted off the upper mold 23 and the casting can be taken out. The above steps are repeated to achieve batch production. This equipment increases the molten metal filling speed by 40% through mold rotation, effectively avoiding defects such as material shortage and porosity. Moreover, the coordinated action of each mechanism has a high degree of automation, requiring no manual intervention and resulting in better performance.
[0029] Optional, please refer to Figure 2 , Figure 4 and Figure 5 The limiting mechanism 3 includes a limiting rod 31 fixedly installed on the upper surface of the turntable 21, and a limiting hole 32 that is connected to the limiting rod 31 is opened at the bottom of the lower mold 22.
[0030] In this embodiment, the limiting rods 31 are vertically welded to the upper surface of the turntable 21, with four rods evenly distributed around the circumference of the turntable 21 at 90° intervals. The lower mold 22 has a corresponding limiting hole 32 at its bottom, and the limiting rods 31 and the limiting holes 32 are fitted with a clearance fit. When installing the lower mold 22, the limiting hole 32 is aligned with the limiting rod 31 and inserted. The radial constraint of the limiting rod 31 limits the position of the lower mold 22, ensuring that the lower mold 22 and the turntable 21 do not rotate relative to each other. When the turntable 21 rotates, the limiting rods 31 drive the lower mold 22 to rotate synchronously, so that the molten metal can quickly expand from the center to the periphery into the polyhedral cavity under the action of centrifugal force during the rotation, resulting in a better casting effect.
[0031] Optional, please refer to Figure 1 and Figure 3 The casting mechanism 4 includes a vertical cylinder 41 fixedly installed on the upper surface of the base 1. A telescopic rod 42 is movably installed in the vertical cylinder 41. A lifting plate 43 is fixedly installed at the top of the telescopic rod 42. A fixing hole is opened on the outer wall of the lifting plate 43 near the middle position, and a casting pipe 44 is fixedly installed in the fixing hole. A casting hopper 45 is connected to the top of the casting pipe 44.
[0032] In this embodiment, the vertical cylinder 41 is vertically welded to the upper surface of the base 1, the telescopic rod 42 is clearance-fitted with the vertical cylinder 41, the lifting plate 43 is horizontally fixed to the top of the telescopic rod 42, and the casting pipe 44 is fixed to the fixing hole of the lifting plate 43 through a flange. Before casting, by controlling the lifting plate 43 to descend, the bottom end of the casting pipe 44 can enter the casting port 24. The molten metal is poured into the casting hopper 45 and flows precisely into the mold cavity through the casting pipe 44, effectively avoiding the situation of the molten metal splashing outward. After casting is completed, the lifting plate 43 is driven to rise, so that the casting pipe 44 is removed from the casting port 24, which facilitates the removal of the movable plate 2.
[0033] Optional, please refer to Figure 1 and Figure 2 The moving mechanism 5 includes electric slide rails 51 symmetrically mounted on the upper surface of the base 1 and located on both sides of the movable plate 2. Electric sliders 52 are slidably arranged in the electric slide rails 51. Mounting grooves 54 are opened on both outer walls of the movable plate 2, and mounting rods 55 are fixedly installed in the mounting grooves 54. Push blocks 53 are slidably sleeved on the outer side of the mounting rods 55.
[0034] In this embodiment, the electric slide rail 51 is symmetrically fixed to the upper surface of the base 1, and the electric slider 52 and the push block 53 are fixed by bolts; the mounting groove 54 is opened on both sides of the movable plate 2, the mounting rod 55 is horizontally welded in the mounting groove 54, and the push block 53 is slidably sleeved on the outside of the mounting rod 55 and can move along the axial direction of the mounting rod 55; when the movable plate 2 needs to be moved, the electric slide rail 51 drives the electric slider 52 to move, which in turn drives the push block 53 to move, and the push block 53 pushes the movable plate 2 to slide along the slide groove 11, so as to realize the flexible movement operation of the movable plate 2.
[0035] Optional, please refer to Figure 2 and Figure 3 A spring 61 is sleeved on the outside of the mounting rod 55. One end of the spring 61 is connected to the inner wall of the mounting groove 54. A movable block 62 is fixedly installed on the other end of the spring 61 and sleeved on the outside of the mounting rod 55. A push rod 63 is fixedly installed on the upper surface of the push block 53 and the top of the push rod 63 is semi-circular. An adjusting block 64 that cooperates with the push rod 63 is also fixedly installed on the lower surface of the lifting plate 43. The adjusting block 64 is in the shape of an inverted trapezoid and is used to cause the casting pipe 44 to be inserted into the casting port 24 when the push rod 63 is disengaged from the adjusting block 64. A baffle 65 is also fixedly installed on the outside of the telescopic rod 42 to limit the downward movement of the lifting plate 43.
[0036] In this embodiment, when the electric slider 52 drives the push block 53 to move, the push block 53 can push the movable plate 2 to move with the help of the movable block 62 and the spring 61, so that the movable plate 2 moves downward towards the lifting plate 43. During the movement, the push rod 63 on the surface of the push block 53 will first contact the inverted trapezoidal adjusting block 64 at the bottom of the lifting plate 43. The push rod 63 with a semi-circular top will move along the inclined surface of one side of the adjusting block 64 until the push rod 63 moves to the bottom of the adjusting block 64. At this time, the lifting plate 43 is lifted up, so that the casting pipe 44 rises together, avoiding the casting pipe 44 from obstructing the movement of the mold. When the movable plate 2 moves to a state where it is in contact with one side of the slide 11, the casting pipe 44 is just aligned with the casting port 24. As the push block 53 moves further, the position of the mold no longer changes, but the push block 53 will cause the movable block 62 to compress the spring 61, so that the push rod 63 on the surface of the push block 53 moves further. Until the push rod 63 moves away from the bottom of the adjusting block 64, the lifting plate 43 automatically moves down under gravity, allowing the casting pipe 44 to automatically insert into the casting port 24, facilitating subsequent precise casting. When casting is complete and the movable plate 2 needs to be moved out from under the lifting plate 43, the electric slider 52 drives the push block 53 to move in the opposite direction. The push block 53 will first move in the mounting grooves 54 on both sides of the movable plate 2. The push rod 63 on the surface of the push block 53 will cooperate with the adjusting block 64 to lift the lifting plate 43 again. As the push block 53 moves further, it will move the movable plate 2 together with the push block 53 until it is in contact with the side wall of the mounting groove 54. At this time, the casting pipe 44 has been automatically removed from the casting port 24, so it will not obstruct the movement of the mold. This structure realizes the automatic lifting operation of the casting pipe 44 when the movable plate 2 moves in and out of the casting mechanism 4, effectively avoiding the risk of splashing of molten metal during casting, and has a better performance.
[0037] Optional, please refer to Figure 2 , Figure 4 and Figure 5 It also includes a locking mechanism 7, which is located above the turntable 21 and is used to lock the upper mold 23 and the lower mold 22 before casting.
[0038] In this embodiment, the locking mechanisms 7 are symmetrically distributed on both sides of the turntable 21, with each set of locking mechanisms 7 corresponding to one locking plate 71, ensuring that the upper mold 23 is subjected to uniform force. The locking mechanisms 7 rotate synchronously with the mold and the turntable 21, without affecting the rotary casting operation. After the upper mold 23 and the lower mold 22 are closed, the locking mechanisms 7 are activated to apply a downward locking force to the locking plate 71, so that the upper and lower molds 22 fit tightly together, preventing molten metal leakage and mold separation during the casting process. After casting is completed, the locking mechanisms 7 are unlocked, making it easy to demold.
[0039] Optional, please refer to Figure 2 , Figure 4 and Figure 5The locking mechanism 7 includes a locking plate 71 symmetrically installed on the lower surface of the upper mold 23, and the locking plate 71 is L-shaped. The upper surface of the turntable 21 is provided with a locking assembly, which is used to apply a downward pulling force to the locking plate 71 after the upper mold 23 and the lower mold 22 are closed. The locking assembly includes a rotating rod 72 rotatably installed on the upper surface of the turntable 21, and a locking rod 73 is fixedly installed at the end of the rotating rod 72. A collar 74 is sleeved on the outer side of the locking rod 73. A telescopic cylinder 75 is also rotatably installed on the upper surface of the turntable 21, and the telescopic end of the telescopic cylinder 75 is connected to the outer wall of the collar 74.
[0040] In this embodiment, the locking plate 71 is L-shaped, with its horizontal section welded to the lower surface of the upper mold 23. The locking assembly is installed on the upper surface of the turntable 21, corresponding one-to-one with the locking plate 71, ensuring that the pulling force on the locking plate 71 is vertically downward when locked. The rotating rod 72 is rotatably installed on the upper surface of the turntable 21 via a pin, and the locking rod 73 is vertically welded to the end of the rotating rod 72. The collar 74 is slidably sleeved on the outside of the locking rod 73. The telescopic cylinder 75 is rotatably installed on the surface of the turntable 21 via a hinge, and its telescopic end is welded to the collar 74. When the upper mold 23 and the lower mold 22 are normally closed, the locking rod 73... Located on one side of the locking plate 71, it will not obstruct the mold closing process. After the upper mold 23 and the lower mold 22 are normally closed, the telescopic cylinder 75 can be contracted to pull the collar 74 to drive the locking rod 73 to rotate around the axis of the rotating rod 72, so that the locking rod 73 moves to the surface of the horizontal part of the L-shaped locking plate 71 and applies a certain downward pressure to the horizontal part of the locking plate 71, thereby realizing the locking operation. When unlocking, the telescopic cylinder 75 extends and pushes the locking rod 73 out from above the locking plate 71, which will not obstruct the demolding process and has a better effect.
[0041] Optional, please refer to Figure 6 The drive assembly 8 includes a reducer 81 fixedly mounted on the lower surface of the movable plate 2. A drive motor 82 is fixedly mounted on the lower surface of the reducer 81. The drive end of the drive motor 82 is connected to the input shaft of the reducer 81. The output shaft of the reducer 81 is connected to the lower surface of the turntable 21. The bottom of the base 1 is also provided with a movable opening 83 that communicates with the slide groove 11 to provide moving space for the reducer 81 and the drive motor 82.
[0042] In this embodiment, the drive motor 82 and the reducer 81 are fixed to the lower surface of the movable plate 2 via a flange, and the output shaft of the reducer 81 is connected to the center of the turntable 21 via a coupling. After the drive motor 82 starts, the power is reduced and increased in torque by the reducer 81 and then transmitted to the turntable 21, causing the turntable 21 to rotate smoothly, thereby making the mold rotate synchronously. During casting, the rotating mold causes the molten metal to expand rapidly from the center to the surroundings under the action of centrifugal force, and evenly fills all corners of the polyhedral cavity. By adjusting the motor speed, the rotation speed of the turntable 21 can be controlled to adapt to molten metal of different viscosities and cavities of different structures, so as to realize efficient casting operation of multiple stations.
[0043] Optional, please refer to Figure 4 Lifting rings 26 are fixedly installed on both outer walls of the upper mold 23 and the lower mold 22 to assist in loading and unloading the upper mold 23 and the lower mold 22.
[0044] In this embodiment, the lifting ring 26 is forged from Q235B steel and threadedly connected to the outer walls of both sides of the upper mold 23 and the lower mold 22. When loading and unloading the mold, the hook of the lifting equipment is hooked into the lifting ring 26. Through the lifting and moving of the lifting equipment, the mold can be quickly installed and disassembled without manual handling, making it more convenient to use.
[0045] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
