Description

Technical Field

[0001] The present invention relates to the technical field of casting molds, and more specifically, to a centrifugal casting mold for an automotive shoe block. Background Art

[0002] The brake shoe block is a very important component in the automotive braking system. It is usually installed on the brake drum. Under the action of the brake cam or push rod, it is pushed outwards to press the brake drum, thereby generating a braking effect. Most brake shoe blocks are copper castings. The manufacture of copper castings mostly uses centrifugal casting die-casting molds. It is to pour liquid metal into a rotating die-casting mold. Under the action of centrifugal force, the liquid metal fills the die-casting mold and solidifies. The gas and impurities in the liquid metal are more likely to float out. At the same time, the metal liquid is under the action of centrifugal pressure during the solidification process, making the structure of the casting more dense, reducing defects such as shrinkage cavities and porosity, and improving the mechanical properties and pressure resistance of the casting.

[0003] After retrieval, a centrifugal casting mold is proposed in the casting device and its casting method with the publication number CN108057865B, which includes a centrifugal lower mold, a centrifugal upper mold, a sand mold, a top mold device and a centrifuge. The centrifugal lower mold forms a receiving cavity. The centrifugal lower mold is provided with guide rods on the outside of the receiving cavity. The centrifugal upper mold is provided with a cavity for receiving the sand mold. The bottom surface of the sand mold forms a riser pouring channel, and a pouring gate is provided on the top surface of the riser pouring channel. At least two annular casting cavities are provided around the riser pouring channel. Each casting cavity is recessed inward from the bottom surface of the sand mold. Each casting cavity is provided with a connecting channel communicating with the riser pouring channel. The top mold device includes a starting template arranged in the receiving cavity, a top shaft connected to the lower part of the starting template, a top template arranged below the centrifugal lower mold and a driving device arranged below the top template. The two ends of the guide rod are respectively fixed on the centrifugal upper mold and the top template. The castings made by this casting device have uniform structures and reduce defects such as gas holes and sand holes. However, the above patent still has deficiencies in actual use: During the centrifugal casting process, the mold rotates at a high speed. Therefore, the molten metal used to cast copper castings will rotate after entering the mold. Under the action of centrifugal force, the impurities carried by the metal raw materials themselves and the impurities and air adsorbed during the melting and transportation process will accumulate in the inner circle of the casting. After the copper casting is formed, a layer of impurities will adhere to the inner circle, which requires manual cleaning after manual demolding, which is relatively inconvenient and affects the production efficiency of copper castings.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] For this reason, the present invention provides a centrifugal casting mold for an automotive shoe block. Refer to Figures 1 to 9 as shown, which includes a mold unit and a cleaning unit; The mold unit includes a centrifuge 11, a base 12, a support 13, and an arc-shaped mold 14. The base 12 is arranged on the upper top surface of the centrifuge 11. The supports 13 are distributed at the four corners of the upper top surface of the base 12. The arc-shaped mold 14 is limited and slidably inserted through the middle of the support 13; The centrifuge 11 drives the base 12 to rotate rapidly. A pouring container is used to inject molten metal into the arc-shaped mold 14 from its upper part. Under the action of rotational centrifugal force, it is evenly distributed on the inner wall of the mold and solidifies into a copper casting according to the shape of the copper casting mold.

[0023] As Figure 2 , Figure 3 and Figure 5 shown, the cleaning unit includes a central column 21 rotatably connected to the inner wall of the lower bottom surface of the base 12. A combined rod 22 is movably inserted through the top end of the central column 21. A receiving plate 23 is fixedly connected to the upper surface of the base 12. A cleaning plate 24 is arranged on the upper top surface of the receiving plate 23. The combined rod 22 is set as a structural combination of an upper round rod and a lower square rod. The lower square rod is slidably connected to the inside of the central column 21. The top end of the upper round rod penetrates through the receiving plate 23 and is fixedly connected to the cleaning plate 24. A second bevel gear 25 is fixedly sleeved on the outer surface of the central column 21; The adjusting assembly includes a machine box 31 fixedly connected to the inside of the base 12. A motor 32 is slidably connected to the inside of the machine box 31. A first bevel gear 33 is fixedly connected to the driving end of the motor 32. The first bevel gear 33 is meshed with the second bevel gear 25. A driving wheel 34 is fixedly sleeved on the outer surface of the driving end of the motor 32. A damping spring 35 is arranged inside the machine box 31. The end of the damping spring 35 abuts against the tail of the motor 32; After the centrifugal casting of the copper casting is completed, the first bevel gear 33 at the driving end of the motor 32 will drive the second bevel gear 25 to continuously rotate, and then drive the central column 21 to rotate. The combined rod 22 and other structures at the top end of the central column 21 will rotate synchronously with the rotation of the central column 21. During the rotation of the cleaning plate 24, the inner circle of the copper casting can be cleaned, achieving the effect of automatically cleaning the impurities inside the copper casting.

[0024] As Figure 2 , Figure 3 and Figure 6 shown, the lifting assembly includes a driving wheel 41 fixedly sleeved on the outer surface of the central column 21. A threaded rod 42 is rotatably connected to the inner wall of the base 12. One end of the threaded rod 42 away from the inner wall of the base 12 is fixedly connected to a transmission wheel 43. The transmission wheel 43 is indirectly meshed with the driving wheel 41. An eccentric wheel 44 is fixedly sleeved on the outer surface of the threaded rod 42 near the transmission wheel 43. A top plate 45 is fixedly sleeved on the outer surface of the combined rod 22. A return spring 46 is fixedly connected to the upper surface of the top plate 45. The top end of the return spring 46 is fixedly connected to the inner wall of the base 12; During the rotation of the central column 21, the driving wheel 41 will be driven to rotate. During the rotation of the driving wheel 41 around the central column 21, it will indirectly drive the transmission wheel 43 to rotate. After being driven by the driving wheel 41, the transmission wheel 43 will drive the threaded rod 42 to rotate. The eccentric wheel 44 on the outer surface of the end of the threaded rod 42 will push the top plate 45 upward during rotation, and then drive the combined rod 22 to push the cleaning plate 24 upward. When the eccentric wheel 44 is away from the top plate 45, it will move downward under the action of the return spring 46, achieving the purpose of driving the cleaning plate 24 to move up and down, expanding the cleaning range of the cleaning plate 24, and ensuring the thoroughness of cleaning.

[0025] As Figures 2 to 4 shown, the adaptive assembly includes a center rod 51 fixedly connected to the middle of the inner wall of the cleaning plate 24. A collar 52 is movably sleeved on the outer surface of the center rod 51. An arc-shaped rod 53 is hinged to the outer surface of the collar 52. One end of the arc-shaped rod 53 away from the collar 52 is hinged to a scraping plate 54. A storage cavity 55 is opened on the side of the outer surface of the cleaning plate 24. The scraping plate 54 is stored inside the storage cavity 55; The rapid rotation of the cleaning plate 24 will cause the arc-shaped rod 53 and the scraping plate 54 inside it to spread outward under the action of centrifugal force. Under the push of the arc-shaped rod 53, the scraping plate 54 will slide outward from the storage cavity 55 until it contacts the inner ring of the copper casting. Then the rotating scraping plate 54 will continuously clean the inner ring of the copper casting, and can expand adaptively according to the size of the inner ring of the copper casting and the thickness of the impurities, ensuring the completeness of cleaning.

[0026] As Figure 2 and Figure 6 shown, the mold opening assembly includes a strip-shaped plate 61 threadedly connected to the outer surface of the threaded rod 42. A limiting groove 64 is opened on the upper surface of the strip-shaped plate 61. A connecting plate 62 is fixedly sleeved on the outer surface of the arc-shaped mold 14. The bottom end of the connecting plate 62 is fixedly connected to a sliding plate 63. The sliding plate 63 is movably inserted through the upper surface of the base 12. The bottom end of the sliding plate 63 is movably connected inside the limiting groove 64; During the rotation of the threaded rod 42, the strip-shaped plate 61 on its outer surface will move along the inner wall of the base 12. During the movement of the strip-shaped plate 61, the sliding plate 63 will be driven to move towards the corner of the base 12. Then, under the action of the connecting plate 62, the four arc-shaped models will be driven to move outward simultaneously, achieving the effect of automatic mold opening and facilitating the taking of copper castings.

[0027] As Figures 7 to 9 shown, the auxiliary unit includes a reciprocating component arranged inside the base 12 and a vibration component arranged based on the reciprocating component; The reciprocating component includes a shaft rod 71 fixedly connected to the inner wall of the side of the base 12. The end of the shaft rod 71 is rotatably connected with a driven wheel 72. The driven wheel 72 is meshed and connected with the driving wheel 34. The outer surface of the driven wheel 72 is fixedly connected with a push rod 73. The outer surface of the push rod 73 is provided with a return frame 74; The vibration component includes a long rod 81 fixedly connected to the inner wall of the base 12. A pendulum wheel 82 is movably sleeved on the outer surface of the long rod 81. The bottom end of the pendulum wheel 82 is hinged with a pull rod 83. The bottom end of the pull rod 83 is movably sleeved on the top of the return frame 74. The upper surface of the pendulum wheel 82 is evenly distributed with a plurality of paddles 84. A positioning rod 85 is arranged on the inner wall of the upper top surface of the base 12. The bottom end of the positioning rod 85 is fixedly connected with a vibration ball 86; Starting the motor 32 to drive the driving wheel 34 to rotate will drive the driven wheel 72 to rotate synchronously around the shaft rod 71. During the rotation of the driven wheel 72, the push rod 73 will be driven to make a circular motion around the shaft rod 71. During the movement of the push rod 73, the return frame 74 will be pushed upward. The upward push of the return frame 74 on the pull rod 83 will drive the bottom end of the pull rod 83 to deflect around the upper part of the return frame 74. At the same time, the top end of the pull rod 83 will push the pendulum wheel 82, driving the pendulum wheel 82 to rotate around the long rod 81. During the rotation of the pendulum wheel 82, the paddle 84 will drive to collide with the vibration ball 86, forcing the vibration ball 86 to move towards the inner wall of the top surface of the base 12 under the action of inertia until a collision occurs, achieving the effect of applying frequent vibration to the upper top surface of the base 12. Combining with the centrifugal force of centrifugal casting can increase the efficiency of removing gas and impurities, and effectively reduce defects such as air holes and shrinkage porosity in copper castings.

[0028] In the technical solution provided by the present invention, during the centrifugal casting of copper castings, the centrifuge 11 is started to drive the base 12 to rotate rapidly. A pouring container is used to inject the molten metal into the arc-shaped mold 14 from its upper part. Under the action of the rotational centrifugal force, it is evenly distributed on the inner wall of the mold and solidifies into a copper casting according to the shape of the copper casting mold. The motor 32 placed in the machine box 31 will move in a direction away from the center of the base 12 under the action of the centrifugal force, and will squeeze the damping spring 35. As the motor 32 moves, the driving wheel 34 fixed to the outer surface of the driving end of the motor 32 meshes with the driven wheel 72. At this time, when the motor 32 is started to drive the driving wheel 34 to rotate, it will drive the driven wheel 72 to rotate synchronously around the shaft rod 71. During the rotation of the driven wheel 72, it will drive the push rod 73 to make a circular motion around the shaft rod 71. During the movement of the push rod 73, it will push the return frame 74 to move upward. Since the upper part of the return frame 74 is movably connected to the pull rod 83 and the pull rod 83 is limited by the long rod 81, when the return frame 74 pushes the pull rod 83 upward, it will drive the bottom end of the pull rod 83 to deflect around the upper part of the return frame 74. At the same time, the top end of the pull rod 83 will push the pendulum wheel 82 to drive the pendulum wheel 82 to rotate around the long rod 81. During the rotation of the pendulum wheel 82, it will drive the dial 84 to collide with the vibration ball 86, forcing the vibration ball 86 to move towards the inner wall of the top surface of the base 12 under the action of inertia until a collision occurs. Then, it will move downward under the driving of the reaction force of the collision force. This process is repeated, achieving the effect of frequently vibrating the upper top surface of the base 12, achieving the purpose of vibrating the arc-shaped mold 14. It can effectively break the surface tension of the bubbles in the liquid copper, accelerate the aggregation and discharge of the bubbles, and cooperate with the centrifugal force of the centrifugal casting to increase the efficiency of removing gas and impurities, effectively reduce defects such as pores and shrinkage porosity in the copper casting, improve the density and mechanical properties of the copper casting, and at the same time can improve the fluidity of the liquid metal, making the shape of the copper casting more complete and the dimensional accuracy higher; After the centrifugal casting of the copper casting is completed, the centrifuge 11 stops running, and structures such as the base 12 stop rotating. The motor 32 will reset under the action of the resilience of the damping spring 35. At this time, the driving wheel 34 and the driven wheel 72 are staggered, but the bevel gear one 33 and the bevel gear two 25 are engaged. After the copper casting cools down, the motor 32 is started. At this time, the bevel gear one 33 at the driving end of the motor 32 will drive the bevel gear two 25 to rotate continuously, and then drive the central column 21 to rotate. Structures such as the combined rod 22 at the top of the central column 21 will rotate synchronously with the rotation of the central column 21. During the rotation of the cleaning disc 24, the inner ring of the copper casting can be cleaned, achieving the effect of automatically cleaning the impurities in the inner ring of the copper casting. Moreover, since it rotates counterclockwise at this time, the rapid rotation of the cleaning disc 24 will cause the arc-shaped rod 53 and the scraping plate 54 inside it to spread outwards under the action of centrifugal force. Under the push of the arc-shaped rod 53, the scraping plate 54 will slide outwards from the storage cavity 55 until it contacts the inner ring of the copper casting. Then, the rotating scraping plate 54 will continuously clean the inner ring of the copper casting and can expand adaptively according to the size of the inner ring of the copper casting and the thickness of the impurities, ensuring the completeness of the cleaning. During the rotation of the central column 21, the driving wheel 41 will be driven to rotate. Since the driving wheel 41 is a special-shaped gear structure with a small-section rack, during the rotation around the central column 21, the driving wheel 41 will indirectly drive the transmission wheel 43 to rotate. After being driven by the driving wheel 41, the transmission wheel 43 will drive the threaded rod 42 to rotate. The eccentric wheel 44 on the outer surface of the end of the threaded rod 42 will push the top plate 45 upwards during rotation, and then drive the combined rod 22 to push the cleaning disc 24 upwards. After the eccentric wheel 44 and the top plate 45 are separated, it will move downwards under the action of the reset spring 46, achieving the purpose of driving the cleaning disc 24 to move up and down, expanding the cleaning range of the cleaning disc 24, and ensuring the thoroughness of the cleaning; During the rotation of the threaded rod 42, the strip-shaped plate 61 on its outer surface will move along the inner wall of the base 12. Since the bottom end of the sliding plate 63 is limited to slide inside the limiting groove 64, during the movement of the strip-shaped plate 61, the sliding plate 63 will be driven to move towards the corner direction of the base 12. Then, under the action of the connecting plate 62, the four arc-shaped models will be simultaneously pulled outwards, achieving the effect of automatic mold opening and facilitating the taking of the copper casting. Then, the motor 32 rotates in the reverse direction. At this time, the central rod rotates in the reverse direction, resulting in the cleaning disc 24 rotating clockwise. When the arc-shaped plate rotates clockwise, it will approach and fit the central rod 51 in the middle, and then the scraping plate 54 will be received into the storage cavity 55. Then, the reverse rotation of the threaded rod 42 will drive the arc-shaped mold 14 to approach and merge towards the center of the base 12, and the cleaning disc 24 will also return to the receiving disc 23 under the action of the reset spring 46, facilitating the centrifugal casting of the next copper casting.
