[0002] As a core component of the vehicle braking system, the performance of the automobile brake disc directly affects the braking efficiency, thermal decay characteristics and safety. The casting mold is a key equipment for mass production of brake discs, and its technological development is driven by material innovation, process upgrading and market demand. Traditional molds are mostly one-piece steel molds, with pre-fixed cavity size and core structure, only suitable for single-specification brake discs. The molds are made of high-temperature resistant alloy steel (such as H13 steel) and are surface-nitrided to resist high-temperature molten iron (about 1400℃) erosion. The development cycle of a single mold is 3-6 months, and the cost is 10-50 million yuan. The economic efficiency of small batch orders is poor.

[0038] The working principle of the application is:
[0039] When adjusting, the casting mold is adjusted according to the size of the automobile brake disc to be cast. When the outer diameter of the friction surface 7 needs to be increased, the upper mold outer ring clamping device 502 is first turned downward, the upper mold outer ring bearing 5021 is driven downward by the downward rotation of the upper mold outer ring clamping device 502, the upper mold outer ring clamping lever 5022 is expanded outward by the fixed positioning pin, the upper mold outer ring clamping foot 5023 is expanded outward by the fixed positioning pin, thereby achieving the effect of loosening the upper mold outer adjusting ring 504, the inner ring of the upper mold outer adjusting ring 504 is then raised, the raised part is rotated to the upper mold outer ring adjusting fixed groove 5014, the upper mold outer ring limiting strip 5041 is fixed in the upper mold outer ring adjusting fixed groove 5014, the unadjusted part of the upper mold outer adjusting ring 504 is fixed in the upper mold outer ring initial fixed groove 5013 by the upper mold outer ring limiting strip 5041, and finally the upper mold outer ring clamping device 502 is turned upward, the upper mold outer ring bearing 5021 is driven upward by the upward rotation of the upper mold outer ring clamping device 502, the upper mold outer ring clamping lever 5022 is retracted inward by the fixed positioning pin, the upper mold outer ring clamping foot 5023 is retracted inward by the fixed positioning pin, thereby achieving the effect of clamping the upper mold outer adjusting ring 504;
[0040] When the inner diameter of the friction surface 7 needs to be reduced, the upper mold inner ring clamping device 503 is first turned downward, the upper mold inner ring bearing 5031 is driven downward by the downward rotation of the upper mold inner ring clamping device 503, the upper mold inner ring clamping lever 5032 is expanded outward by the fixed positioning pin, the upper mold inner ring clamping foot 5033 is expanded outward by the fixed positioning pin, thereby achieving the effect of loosening the upper mold inner adjusting ring 505, the outer ring of the upper mold inner adjusting ring 505 is then raised, the raised part is rotated to the upper mold inner ring adjusting fixed groove 5012, the upper mold inner ring limiting strip 5051 is fixed in the upper mold inner ring adjusting fixed groove 5012, the unadjusted part of the upper mold inner adjusting ring 505 is fixed in the upper mold inner ring initial fixed groove 5011 by the upper mold inner ring limiting strip 5051, and finally the upper mold inner ring clamping device 503 is turned upward, the upper mold inner ring bearing 5031 is driven upward by the upward rotation of the upper mold inner ring clamping device 503, the upper mold inner ring clamping lever 5032 is retracted inward by the fixed positioning pin, the upper mold inner ring clamping foot 5033 is retracted inward by the fixed positioning pin, thereby achieving the effect of clamping the upper mold inner adjusting ring 505;
[0041] When the outer diameter of the mounting surface 8 needs to be increased, first rotate the lower mold outer ring clamping device 602 upward, the lower mold outer ring clamping device 602 rotates upward to drive the lower mold outer ring bearing 6021 to move upward, the lower mold outer ring bearing 6021 moves upward to make the lower mold outer ring clamping rod 6022 expand outward through the fixed positioning pin, the lower mold outer ring clamping rod 6022 expands outward through the fixed positioning pin to drive the lower mold outer ring clamping foot 6023 to expand outward, thereby achieving the effect of loosening the lower mold outer adjusting ring 604, then lower the inner ring of the lower mold outer adjusting ring 604, rotate the lowered part to the lower mold outer ring adjusting fixed groove 6014, fix the lower mold outer ring limiting strip 6041 in the lower mold outer ring adjusting fixed groove 6014, fix the unadjusted part of the lower mold outer adjusting ring 604 in the lower mold outer ring initial fixed groove 6013 through the lower mold outer ring limiting strip 6041, and finally rotate the lower mold outer ring clamping device 602 downward, the lower mold outer ring clamping device 602 rotates downward to drive the lower mold outer ring bearing 6021 to move downward, the lower mold outer ring bearing 6021 moves downward to make the lower mold outer ring clamping rod 6022 contract inward through the fixed positioning pin, the lower mold outer ring clamping rod 6022 contracts inward through the fixed positioning pin to drive the lower mold outer ring clamping foot 6023 to contract inward, thereby achieving the effect of clamping the lower mold outer adjusting ring 604;
[0042] When the inner diameter of the mounting surface 8 needs to be reduced, first rotate the lower mold inner ring clamping device 603 upward, the lower mold inner ring clamping device 603 rotates upward to drive the lower mold inner ring bearing 6031 to move upward, the lower mold inner ring bearing 6031 moves upward to make the lower mold inner ring clamping rod 6032 expand outward through the fixed positioning pin, the lower mold inner ring clamping rod 6032 expands outward through the fixed positioning pin to drive the lower mold inner ring clamping foot 6033 to expand outward, thereby achieving the effect of loosening the lower mold inner adjusting ring 605, then lower the outer ring of the lower mold inner adjusting ring 605, rotate the lowered part to the lower mold inner ring adjusting fixed groove 6012, fix the lower mold inner ring limiting strip 6051 in the lower mold inner ring adjusting fixed groove 6012, fix the unadjusted part of the lower mold inner adjusting ring 605 in the lower mold inner ring initial fixed groove 6011 through the lower mold inner ring limiting strip 6051, and finally rotate the lower mold inner ring clamping device 603 downward, the lower mold inner ring clamping device 603 rotates downward to drive the lower mold inner ring bearing 6031 to move downward, the lower mold inner ring bearing 6031 moves downward to make the lower mold inner ring clamping rod 6032 contract inward through the fixed positioning pin, the lower mold inner ring clamping rod 6032 contracts inward through the fixed positioning pin to drive the lower mold inner ring clamping foot 6033 to contract inward, thereby achieving the effect of clamping the lower mold inner adjusting ring 605;
[0043] When the thickness of the installation surface 8 needs to be increased, the upper mold adjusting device 5 is first rotated downward to loosen the upper mold inner adjusting ring 505. The upper mold inner adjusting ring 505 is loosened by rotating the upper mold inner ring clamping device 503 downward, which drives the upper mold inner ring bearing 5031 to move downward. The upper mold inner ring bearing 5031 moving downward causes the upper mold inner ring clamping rod 5032 to expand outward through the fixed positioning pin, which drives the upper mold inner ring clamping foot 5033 to expand outward through the fixed positioning pin, thereby achieving the effect of loosening the upper mold inner adjusting ring 505. Then, the upper mold inner ring limiting strip 5051 in the upper mold inner ring initial fixed groove 5011 and the upper mold inner ring adjusting fixed groove 5012 is simultaneously raised to the required thickness for adjustment, so that the outer ring in the upper mold inner adjusting ring 505 is raised to the required thickness for adjustment. The upper mold inner ring clamping device 503 is then rotated upward, which drives the upper mold inner ring bearing 5031 to move upward. The upper mold inner ring bearing 5031 moving upward causes the upper mold inner ring clamping rod 5032 to contract inward through the fixed positioning pin, which drives the upper mold inner ring clamping foot 5033 to contract inward through the fixed positioning pin, thereby achieving the effect of clamping the upper mold inner adjusting ring 505. The lower mold adjusting device 6 is first rotated upward to loosen the lower mold inner adjusting ring 605. The lower mold inner adjusting ring 605 is loosened by rotating the lower mold inner ring clamping device 603 upward, which drives the lower mold inner ring bearing 6031 to move upward. The lower mold inner ring bearing 6031 moving upward causes the lower mold inner ring clamping rod 6032 to expand outward through the fixed positioning pin, which drives the lower mold inner ring clamping foot 6033 to expand outward through the fixed positioning pin, thereby achieving the effect of loosening the lower mold inner adjusting ring 605. Then, the lower mold inner ring limiting strip 6051 in the lower mold inner ring initial fixed groove 6011 and the lower mold inner ring adjusting fixed groove 6012 is simultaneously raised to the required thickness for adjustment, so that the outer ring in the lower mold inner adjusting ring 605 is raised to the required thickness for adjustment. The lower mold inner ring clamping device 603 is then rotated downward, which drives the lower mold inner ring bearing 6031 to move downward. The lower mold inner ring bearing 6031 moving downward causes the lower mold inner ring clamping rod 6032 to contract inward through the fixed positioning pin, which drives the lower mold inner ring clamping foot 6033 to contract inward through the fixed positioning pin, thereby achieving the effect of clamping the lower mold inner adjusting ring 605.
[0044] When the thickness of the mounting surface 8 needs to be reduced, the upper die adjusting device 5 first rotates the upper die inner ring clamping device 503 downward, which drives the upper die inner ring bearing 5031 to move downward, and the upper die inner ring bearing 5031 moving downward makes the upper die inner ring clamping rod 5032 expand outward through the fixed positioning pin, and the upper die inner ring clamping rod 5032 expanding outward drives the upper die inner ring clamping foot 5033 to expand outward through the fixed positioning pin, thereby achieving the effect of loosening the upper die inner adjusting ring 505, and then the upper die inner ring limiting strip 5051 in the upper die inner ring initial fixed groove 5011 and the upper die inner ring adjusting fixed groove 5012 is lowered to the required thickness to be adjusted, so that the outer ring to be adjusted and the inner ring not to be adjusted in the upper die inner adjusting ring 505 are lowered to the required thickness to be adjusted, and then the upper die inner ring clamping device 503 is rotated upward, which drives the upper die inner ring bearing 5031 to move upward, and the upper die inner ring bearing 5031 moving upward makes the upper die inner ring clamping rod 5032 contract inward through the fixed positioning pin, and the upper die inner ring clamping rod 5032 contracting inward drives the upper die inner ring clamping foot 5033 to contract inward through the fixed positioning pin, thereby achieving the effect of clamping the upper die inner adjusting ring 505, and the lower die adjusting device 6 first rotates the lower die inner ring clamping device 603 upward, which drives the lower die inner ring bearing 6031 to move upward, and the lower die inner ring bearing 6031 moving upward makes the lower die inner ring clamping rod 6032 expand outward through the fixed positioning pin, and the lower die inner ring clamping rod 6032 expanding outward drives the lower die inner ring clamping foot 6033 to expand outward through the fixed positioning pin, thereby achieving the effect of loosening the lower die inner adjusting ring 605, and then the lower die inner ring limiting strip 6051 in the lower die inner ring initial fixed groove 6011 and the lower die inner ring adjusting fixed groove 6012 is lowered to the required thickness to be adjusted, so that the outer ring to be adjusted and the inner ring not to be adjusted in the lower die inner adjusting ring 605 are lowered to the required thickness to be adjusted, and then the lower die inner ring clamping device 603 is rotated downward, which drives the lower die inner ring bearing 6031 to move downward, and the lower die inner ring bearing 6031 moving downward makes the lower die inner ring clamping rod 6032 contract inward through the fixed positioning pin, and the lower die inner ring clamping rod 6032 contracting inward drives the lower die inner ring clamping foot 6033 to contract inward through the fixed positioning pin, thereby achieving the effect of clamping the lower die inner adjusting ring 605.
