Description

Technical Field

[0001] The invention belongs to the technical field of brake disc production, and in particular relates to a brake disc casting device. Background Art

[0002] Brake discs are vulnerable parts of automobile braking systems. With the rapid development of the automobile industry, the market demand for brake discs is huge. During production, the prototype of the brake disc is first cast through a casting process, and then the brake disc casting is turned and finished on a lathe.

[0003] When casting brake discs, due to the different specific usage scenarios of brake discs, some brake discs will have heat dissipation holes and gas discharge holes on their surfaces for better heat dissipation and gas circulation during use. This is convenient for subsequent use. In the prior art, after the brake discs with heat dissipation holes and gas discharge holes are cast, the cast brake discs will be directly transported to the next processing link and then put into use directly. However, in the process of casting the brake discs, a refrigerator is usually used to quickly cool the brake discs in the mold to improve the casting efficiency. However, rapid cooling will cause the inside of the brake disc to produce Larger thermal stress will cause the inner wall of the hole to crack, causing cracks and damage to the inner wall of the heat dissipation hole and the gas discharge hole. The damage to the inner wall of the gas discharge hole will hinder the normal discharge of gas, causing gas to accumulate between the brake disc and the brake pad to form bubbles. These bubbles will reduce the contact area between the brake pad and the brake disc, reduce friction, and thus reduce braking efficiency. When the inner wall of the heat dissipation hole is damaged and cracked, heat will accumulate at the damaged area to form hot spots, affecting the uniform heat dissipation of the brake disc, and may also cause deformation or local damage, greatly reducing the casting effect and reliability of the brake disc.

[0023] The operating principle of the present invention is now described as follows: In the present invention, when the brake disc needs to be cast, the first electric telescopic rod 4 is first controlled to start, driving the upper mold 5 to move downward, so that the upper mold 5 and the lower mold 6 are molded together, and then the molten metal solution is injected into the upper mold 5 and the lower mold 6 after the mold is closed through the liquid inlet of the upper mold 5. After that, the metal solution in the mold is cooled, and the brake disc is cast. Then, the first electric telescopic rod 4 is controlled to contract, driving the upper mold 5 to move upward and return to its original position. At this time, the upper surface of the brake disc is exposed to the outside, and then the two first electric slide rails 112 are controlled to start, driving the first slide plate 113 to move, so that the mounting plate 115 and the third electric telescopic rod 114 move toward the brake disc, and when the center point of the rotating circular plate 117 is at the center of the brake disc, the first electric slide rail 113 is driven to move, and the mounting plate 115 and the third electric telescopic rod 114 move toward the brake disc. After the center point is directly above, the first electric slide rail 112 is controlled to stop, and the third electric telescopic rod 114 is controlled to be extended so that the mounting plate 115 can be under the upper mold 5, so that the mounting plate 115 moves towards the lower mold 6. Then, the fourth electric telescopic rod 116 is controlled to start, driving the rotating disc to move downward, so that the side plate 1210 is close to the brake disc, and then the inner wall of the heat dissipation hole on the surface of the brake disc is first detected for damage and cracks. At this time, the second electric slide rail 122 is controlled to start, driving the second slide plate 123 to move, driving the fixed plate 124 to move to the same plane of one of the heat dissipation holes on the surface of the brake disc, and then the third electric slide rail 125 is controlled to start, driving the third slide plate 126 to move, so that the fifth electric telescopic rod 128 is located at the corresponding heat dissipation hole. The fifth electric telescopic rod 128 is then controlled to start, driving the side plate 1210 and the first ultrasonic detector 1211 to move downward, so that the first ultrasonic detector 1211 moves to the bottom of the heat dissipation hole, and then the second motor 127 and the first ultrasonic detector 1211 are controlled to start at the same time, and the second motor 127 is used to drive the first ultrasonic detector 1211 to rotate, so that the first ultrasonic detector 1211 can detect whether there are any damages or cracks on the inner wall of the heat dissipation hole. At the same time, the air pump 1212 is controlled to start, and air is injected into the connecting pipe 129, discharged through the air outlet 1213, and blown to the inner wall of the heat dissipation hole, so as to blow away the impurities and dust on the inner wall of the heat dissipation hole, so as to prevent the dust and impurities from affecting the first ultrasonic detector 1211 to detect whether there are any damages or cracks on the inner wall of the heat dissipation hole. After the first ultrasonic detector 1211 rotates one circle, the fifth electric telescopic rod 128 is controlled to contract, driving the first ultrasonic detector 1211 to move upward until the detection of whether the inner wall of the heat dissipation hole has cracks and damage is completed. Then, the second electric slide rail 122 and the third electric slide rail 125 are controlled to start, so that the first ultrasonic detector 1211 can be moved to the position of other heat dissipation holes. Then, the inner walls of other heat dissipation holes are detected for damage and cracks according to the above method. After completing the detection of cracks in the heat dissipation holes, when detecting the gas discharge holes, since the shape of the gas discharge holes is mostly V-shaped and evenly arranged on the surface of the brake disc, the first motor 118 is controlled to start first to drive the rotating circular plate 117 to rotate.The connecting plate 135 is rotated to above one of the gas discharge holes, and then the third motor 134 is controlled to start, driving the connecting plate 135 to rotate, so that the inclination angle of the connecting plate 135 is the same as the inclination angle of the half part of the V-shaped gas discharge hole, and then the fourth electric slide rail 132 is controlled to start, driving the fourth slide plate 133 to move, so that the connecting plate 135 is located above the half part of the V-shaped gas discharge hole, and then the sixth electric telescopic rod 138 is controlled to start, driving the corresponding fixed frame 139 to move downward, so that both fixed frames 139 enter the gas discharge hole, and then the second ultrasonic detector 1316 is controlled to start to detect the inner wall of the gas discharge hole, and at the same time, the fifth motor 1319 is controlled to start to drive the second round rod 1318 to rotate, The angle of the air gun 1320 is adjusted so that the air outlet of the air gun 1320 can always correspond to the position where the second ultrasonic detector 1316 detects the inner wall of the gas discharge hole, and the air gun 1320 is controlled to spray air toward the position where the second ultrasonic detector 1316 detects the gas discharge hole, so as to blow away impurities and dust on the inner wall of the gas discharge hole, so as to facilitate the detection of the inner wall of the gas discharge hole.

At this time, the detection of whether the inner wall of the half of the V-shaped gas discharge hole is damaged or cracked is completed, and then the inner wall of the other half of the V-shaped gas discharge hole is detected in the above manner, and then the rotation of the rotating circular plate 117 is controlled, and the above steps are followed to detect whether the inner wall of the gas discharge hole on the surface of other brake discs is cracked or damaged, so as to ensure that the quality of the brake disc leaving the factory meets the subsequent use requirements.After the casting of the brake disc is completed, the inner wall of the heat dissipation holes and the gas discharge holes on the surface of the brake disc can be inspected for cracks and damage to prevent cracks and damage to the inner wall of the heat dissipation holes and the gas discharge holes, thereby avoiding reducing the braking efficiency and affecting the uniform heat dissipation of the brake disc, ensuring that the quality of the factory-produced brake disc meets the subsequent use requirements, and the angle of the connecting plate 135 can be adjusted according to the angle of the V-shaped gas discharge hole, and then the fourth electric slide rail 132 and the fifth electric slide rail 136 are controlled to start, so that the second ultrasonic detector 1316 can detect whether the inner wall of the V-shaped gas discharge hole is damaged or cracked. When the heat dissipation holes and the inner wall of the gas discharge holes are detected, the air gun 1320 and the air outlet 1213 can be used to blow away impurities and dust adhering to the inner wall of the heat dissipation holes and the gas discharge holes, so as to prevent the detector from affecting the detection of the inner wall of the heat dissipation holes and the gas discharge holes, thereby greatly improving the casting effect and reliability of the device during the casting of the brake disc.
