[0002] To put it simply, the brake disc is a round plate that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car.

[0003] The production of brake discs is formed by a casting process. During the casting of brake discs, a casting ladle is needed to transport the molten steel to the designated location. After that, the casting ladle will pour the molten steel in the ladle into the brake disc casting mold smoothly within the specified time according to the pouring speed and angle set by the casting curve;

[0004] However, the traditional casting ladle has an open structure, which causes the temperature in the casting ladle to be easily lost, and the molten steel is easily solidified in the casting ladle, which is not conducive to the stable production of brake discs. Based on this, a brake disc insulation casting device is provided. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 4In an embodiment of the utility model, a brake disc insulation casting device includes a casting assembly 1 consisting of a hanger body 101, a casting bag 102, a rotating shaft 103, a first reducer 104, and a first hand wheel 105. The rotating shaft 103 is symmetrically fixed on both sides of the outer wall of the hanger body 101, the casting bag 102 is distributed on the inner side of the hanger body 101 and is rotatably connected to the hanger body 101 through the rotating shaft 103. The first reducer 104 is fixedly installed on one side of the hanger body 101, a rotating shaft 103 is fixedly connected to the output shaft of the first reducer 104, and the first hand wheel 105 is fixedly connected to the input shaft of the first reducer 104. The top and outer side of the casting bag 102 and the inner side of the hanger body 101 are provided with an insulation shielding assembly 2, and the insulation shielding assembly 2 is used to shield the top opening of the casting bag 102 to achieve the insulation effect of the casting bag 102;

[0031] The heat preservation shielding assembly 2 includes a first shielding unit, a second shielding unit, and a limiting unit;

[0032] The first shielding unit cooperates with the second shielding unit to achieve all-round shielding of the top of the pouring ladle 102. When the pouring ladle 102 is in an upright state, the first shielding unit is opened to pour molten steel into the pouring ladle 102.

[0033] When the pouring ladle 102 is tilted to cast molten steel, the second shielding unit automatically opens to remove the shielding of the pouring opening of the pouring ladle 102. When the pouring ladle 102 is reset to the upright state, the second shielding unit automatically closes to shield the pouring opening of the pouring ladle 102.

[0034] The limiting unit is used to limit the tilt angle of the casting bag 102;

[0035] The first shielding unit includes a second reducer 201, a second hand wheel 202, a connecting arm 203, and a first shielding plate 204;

[0036] The second reducer 201 is fixed to one side of the outer wall of the casting ladle 102, the second hand wheel 202 is fixed to the input shaft of the second reducer 201, the connecting arm 203 is fixed to the top of the output shaft of the second reducer 201, and the first shielding plate 204 is fixed to one side of the connecting arm 203 and is attached to the top of the casting ladle 102, so as to shield half of the top area of ​​the casting ladle 102;

[0037] The second shielding unit includes a second shielding plate 205, an L-shaped base 206, a driven gear 207, and an arc-shaped gear ring 208;

[0038] The second shielding plate 205 is attached to the top of the pouring bag 102 and is symmetrically distributed with the second shielding plate 205. The second shielding plate 205 is used to shield the other half of the top of the pouring bag 102 and the pouring port;

[0039] The L-shaped base 206 is fixed to the side of the casting bag 102 away from the second reducer 201, and the end of the second shielding plate 205 close to the first shielding plate 204 is fixedly connected to a rotating shaft, one side of the rotating shaft extends through the L-shaped base 206 and is fixedly connected to the driven gear 207, and the rotating shaft and the L-shaped base 206 are in a rotationally connected state;

[0040] The arc-shaped gear ring 208 is fixed to the inner side of the hanger body 101 and meshes with the driven gear 207. The center of the arc-shaped gear ring 208 coincides with the center line of the rotating shaft 103. When the casting bag 102 is flipped around the rotating shaft 103, the driven gear 207 rotates under the limiting action of the arc-shaped gear ring 208, thereby realizing the opening operation of the second baffle 205.

[0041] In this embodiment: when the casting assembly 1 is transferred to the vicinity of the brake disc mold and molten steel casting is required, the casting port of the casting ladle 102 can be adjusted to face the brake disc mold, and then the first hand wheel 105 is manually rotated, and the first hand wheel 105 drives the input shaft of the first reducer 104 to rotate, and the internal transmission of the first reducer 10 can drive the rotating shaft 103 to rotate at a low speed, so that the casting ladle 102 is turned over and tilted toward the brake disc mold;

[0042] During this process, the driven gear 207 rotates in a circular motion with the casting ladle 102, and rotates under the limiting action of the arc-shaped gear ring 208. The rotating driven gear 207 drives the second baffle plate 205 to flip through the rotating shaft, so that the second baffle plate 205 rotates and opens. At this time, the blocking of the pouring port of the casting ladle 102 is released, and the molten steel inside the casting ladle 102 can be cast into the brake disc mold through the pouring port.

[0043] After the molten steel casting is completed, the first hand wheel 105 is rotated in the opposite direction to reset the pouring bag 102 to the upright state. At this time, the second shielding plate 205 is synchronously reset to fit on the top of the pouring bag 102 to achieve shielding of the pouring port of the pouring bag 102.

[0044] When it is necessary to pour molten steel into the pouring ladle 102, the second hand wheel 202 can be rotated, and the second hand wheel 202 drives the input shaft of the second reducer 201 to rotate, and the connecting arm 203 can be driven to rotate horizontally through the internal transmission of the second reducer 201, and the connecting arm 203 drives the first shielding plate 204 to rotate horizontally away from the pouring ladle 102, and then the opening of the pouring ladle 102 is released. At this time, the molten steel can be poured into the inside of the pouring ladle 102 from this position. After the molten steel is added, the first shielding plate 204 can be reset;

[0045] Through the coordination of the above multiple parts, when the casting bag 102 is transferred in an upright state, the first shielding plate 204 and the second shielding plate 205 are attached to the top of the casting bag 102, so as to achieve all-round shielding of the top opening and the pouring port of the casting bag 102, thereby effectively improving the thermal insulation effect of the casting bag 102.

[0046] Please refer to Figures 1 to 3 A notch groove 106 is provided at a position where the vertical arm of the hanger body 101 is aligned with the second reducer 201 , and the input shaft of the second reducer 201 extends to above the first reducer 104 through the notch groove 106 , and the second hand wheel 202 is distributed above the first reducer 104 .

[0047] In this embodiment: through this structure, the first hand wheel 105 and the second hand wheel 202 are located on the same side of the hanger body 101, so as to facilitate personnel operation, and the notch groove 106 is used to prevent the input shaft of the second reducer 201 from colliding with the hanger body 101.

[0048] Please refer to Figures 1 to 3 , the limiting unit includes a reinforcing rib 209 and an L-shaped limiting baffle 210;

[0049] The reinforcing rib 209 is fixed to one end of the hanger body 101 and is fixedly connected to the bottom of one side of the arc-shaped toothed ring 208, so as to reinforce the arc-shaped toothed ring 208;

[0050] The L-shaped limit stopper 210 is fixed to the bottom of the reinforcing rib 209 . When the driven gear 207 rotates to the lowest point, the bottom of the driven gear 207 contacts the L-shaped limit stopper 210 . The L-shaped limit stopper 210 is used to limit the downward movement of the driven gear 207 .

[0051] In this embodiment: during the tilting and flipping process of the casting bag 102, the downward movement of the driven gear 207 is limited by the L-shaped limit stopper 210, so as to prevent the casting bag 102 from flipping too much and causing the driven gear 207 to be separated from the arc-shaped gear ring 208;

[0052] It should also be noted that when the pouring bag 102 is reset to the upright state, the second shielding plate 205 and the top of the pouring bag 102 are in contact with each other to limit the position of the pouring bag 102 in the upright state.

[0053] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
