Description

Technical Field

[0001] This utility model relates to the field of brake disc casting technology, and in particular to a brake disc blank casting device. Background Technology

[0002] Brake disc blank casting equipment is the core equipment for realizing the industrial production of brake disc blanks. It is mainly used to melt metal raw materials such as cast iron into liquid state and then cast them into blanks that conform to the preliminary shape of brake discs, which can meet the manufacturing needs of brake systems in the fields of automobiles and construction machinery.

[0003] The gating system guides the molten metal into the pre-made metal mold cavity through structures such as the pouring cup and sprue. Subsequently, the molten metal fills and initially solidifies in the cavity. The forming system, relying on the precise structure of the mold cavity, gives the blank brake disc its initial shape. The cooling rate is controlled by air cooling or water cooling, and combined with real-time monitoring by a temperature measuring instrument, the stability of the blank's metallographic structure is ensured, and the casting of the brake disc blank is finally completed.

[0004] In current technology, some brake disc blank casting devices have difficulty removing air bubbles from the molten metal, which directly leads to porosity defects in the blank. These air bubbles remain inside or on the surface of the casting, which greatly weakens the mechanical properties of the brake disc and reduces its tensile strength and hardness. Therefore, a brake disc blank casting device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a brake disc blank casting device that solves the problem that some brake disc blank casting devices have difficulty in removing air bubbles from molten metal.

[0015] 1. The present invention relates to a brake disc blank casting device, wherein the raw material is first injected into the groove of the casting box, then the motor is started, the motor drives the rotating block to rotate, which in turn causes the semi-circular ring to rotate on the connecting column. The rotation of the semi-circular ring causes the connecting block to swing, and the connecting block in turn causes the fixed plate to swing. Subsequently, the rotating rods at both ends swing accordingly, causing the vibrating block to move up and down in the fixed ring, thereby vibrating the casting box and shaking out air bubbles in the raw material, thus avoiding the increase in the defect rate of the casting caused by air bubbles.

[0016] 2. The present invention relates to a brake disc blank casting device. After casting is completed, hydraulic cylinder two is activated, which moves upward to push moving plate one to move upward, thereby driving the rocker plate and moving plate two to move upward synchronously. When moving plate one moves upward, it pushes fixed column one to drive ejection ring to move upward, and moving plate two drives fixed column two to move upward, so that ejection round plate moves upward and initially ejects the casting. Then, rocker plate moves to the slot of casting box, pushes moving plate two to move a second time, and drives fixed column two and ejection round plate to complete the second ejection.

[0025] The vibration mechanism 5 includes a motor 51, which provides power to the vibration mechanism 5. A rotating block 52 is fixedly connected to the drive end of the motor 51, driving the rotating block 52 to perform circular motion.

A fixed plate 54 is rotatably connected to the outside of the support rod 7, allowing the fixed plate 54 to swing up and down around the support rod 7. Two connecting blocks 56 are fixedly connected to the outside of the fixed plate 54 for fixation. A connecting column 55 is fixedly connected between the two connecting blocks 56, rotatably connecting the connecting column 55 to the semi-circular ring 53, converting the swing of the semi-circular ring 53 into the up and down swing of the fixed plate 54. A rotating rod 57 is rotatably connected to the outside of the fixed plate 54, causing the rotating rod 57 to move up and down when the fixed plate 54 swings. A vibration block 58 is rotatably connected to the bottom of the rotating rod 57. Rotating rod 57 pushes vibrating block 58 to slide. Multiple fixing rings 59 are fixedly connected to the top of casting box 1. The fixing rings 59 restrict the movement trajectory of vibrating block 58, ensuring that vibrating block 58 slides only in the vertical direction. The bottom of motor 51 is fixedly connected to the top of casting box 1, so that motor 51 is installed stably. The outside of vibrating block 58 is slidably connected to the inside of fixing ring 59, ensuring that vibrating block 58 does not deviate when sliding and stably transmits vibration. The top of semi-circular ring 53 is rotatably connected to the outside of connecting column 55, realizing flexible rotation of semi-circular ring 53 and connecting column 55. The bottom of vibrating block 58 contacts the top of casting box 1.

[0026] The casting assembly 4 includes a hydraulic cylinder 41, which provides power for the stamping casting. An upper template 42 is fixedly connected to the drive end of the hydraulic cylinder 41. The upper template 42 moves with the drive end of the hydraulic cylinder 41, stamping and shaping the raw material in the casting box 1. Two limiting posts 43 are fixedly connected to the top of the casting box 1. The limiting posts 43 restrict the movement trajectory of the upper template 42, ensuring that the upper template 42 moves only in the vertical direction, thus improving stamping accuracy. A spring 44 is sleeved on the outside of the limiting posts 43. The spring 44 is activated when the upper template 42 moves upward.

A movable plate 62 is fixedly connected to the drive end of the second hydraulic cylinder 61. When the drive end of the second hydraulic cylinder 61 extends or retracts, it drives the movable plate 62 to move up and down synchronously. A rocker arm 63 is rotatably connected to the top of the movable plate 62. When the movable plate 62 rises, it pushes the rocker arm 63 to move. A fixed column 65 is fixedly connected to the top of the movable plate 62. The movable plate 62 drives the fixed column 65 to move up and down synchronously. An ejection ring 66 is fixedly connected to the top of the fixed column 65. The fixed column 65 moves itself, causing the ejection ring 66 to rise. A second movable plate 64 is slidably connected to the outside of the fixed column 65. The movable plate 64 can slide up and down along the axis of the fixed column 65. The top of the movable plate 64 is fixedly connected to the fixed column 67. When the movable plate 64 rises, it drives the fixed column 67 to move synchronously. The top of the fixed column 67 is fixedly connected to the ejector plate 68. The fixed column 67 moves to drive the ejector plate 68 to rise. The hydraulic cylinder 61 is externally fixedly connected to the inside of the casting box 1, so that the hydraulic cylinder 61 is stably installed and the power output is stable during the ejection process. The bottom of the movable plate 64 contacts the top of the rocker 63. When the rocker 63 rotates, it pushes the movable plate 64 to slide upward along the fixed column 65 through the contact between the top of the rocker 63 and the movable plate 64, thereby realizing the secondary ejection action.

[0028] Working principle: The raw material is injected into the groove of the casting box 1. The motor 51 is started. The motor 51 drives the rotating block 52 to rotate. The rotating block 52 drives the semi-circular ring 53 to rotate. The semi-circular ring 53 rotates on the connecting column 55. The rotation of the semi-circular ring 53 drives the connecting block 56 to swing. The swing of the connecting block 56 drives the fixed plate 54 to swing, thereby driving the rotating rods 57 at both ends to swing. The swing of the rotating rods 57 drives the vibrating block 58 to move up and down inside the fixed ring 59, generating vibration on the casting box 1. This vibrates out the air bubbles in the raw material in the groove of the casting box 1, preventing high casting defects caused by air bubbles.

[0029] Start hydraulic cylinder 41, which drives the upper template 42 to move downward to cast the raw material in casting box 1. The limiting column 43 plays a limiting role to prevent the upper template 42 from deviating during the movement. The spring 44 prevents the upper template 42 from being damaged due to excessive reset.

[0030] After casting is completed, hydraulic cylinder 2 61 is activated. Hydraulic cylinder 2 61 moves upward, pushing moving plate 1 62 upward. Moving plate 1 62 moves upward, causing rocker plate 63 and moving plate 2 64 to move upward simultaneously. Moving plate 1 62 moves upward, pushing fixed column 1 65 to move ejection ring 66 upward. Moving plate 2 64 moves fixed column 2 67 upward. Fixed column 2 67 moves upward, causing ejection disc 68 to move upward, ejecting the casting. Rocker plate 63 moves to the slot in casting box 1, moving plate 2 64 a second time, causing moving plate 2 64 to drive fixed column 2 67 to push ejection disc 68 for a second ejection.
