In terms of stamping technology, compared with other stamping parts, the automobile roof cover has the characteristics of thin material, complex shape, and mostly three-dimensional curved surface, high surface quality and precision requirements. The quality of automobile roof processing will directly affect the appearance and quality of the whole vehicle.

[0003] The problem that most automobile molds for automobile roofs are not convenient for removing processed parts and the internal temperature is high and it is inconvenient to open the mold, which reduces the processing efficiency, has not been solved. The prior art proposes an automobile mold for automobile roofs, as recorded in patent CN216729097U, a groove is arranged in the middle position of the upper end surface of the base, and a cooling layer B is arranged on the lower end surface of the groove, and a fan cavity is arranged above the front and rear of the base, and a fan body is fixedly installed on the inner wall of the fan cavity, and a plurality of through holes are evenly arranged above the front end surface and the rear end surface of the groove, and circular grooves are arranged on both sides of the groove, and an electric push rod is fixedly installed on the upper end surface of the circular groove, and a push plate is fixedly installed on the upper end surface of the electric push rod, and a lower mold is fixedly installed on the upper end surface of the groove, and a workpiece is arranged above the lower mold, and strip grooves are arranged on both sides above the groove, and threaded holes are arranged above both sides of the outer surface of the base, and threaded rods are arranged on the inner side of the threaded holes, and clamps are arranged on the opposite sides of the outer surfaces of the two threaded rods, and the bottom A support plate is fixedly installed at the rear of the upper end surface of the seat, a top plate is fixedly installed above the front end surface of the support plate, hydraulic cylinders are fixedly installed on both sides of the upper end surface of the top plate, a lifting plate is fixedly installed below the two hydraulic cylinders, a cooling layer A is provided below the inside of the lifting plate, an upper mold is fixedly installed on the lower end surface of the lifting plate, a cold water tank is fixedly installed below the rear end surface of the support plate, a water pump B is installed in front of one side of the upper end surface of the cold water tank, a water pump A is fixedly installed behind the water pump B, and the two screw A rocker is fixedly installed on the opposite side of the outer surface of the threaded rod, the threaded rod is screwed into the threaded hole, the threaded rod is rotatably connected to the clamping plate through a bearing, a U-shaped water pipe A is arranged inside the cooling layer A, the water pump A is connected to the U-shaped water pipe A through a retractable hose, a U-shaped water pipe B is arranged inside the cooling layer B, the water pump B is connected to the U-shaped water pipe B through a connecting pipe, an anti-slip pad is fixedly connected to the opposite side of the outer surface of the two clamping plates through a slot, and the upper end of the push plate is covered with a rubber pad;

[0004] However, in this utility model, the fan cavity is connected to the outside world, so that the deformed material during stamping can easily affect the fan cavity and the internal fan body. The lifting and lowering of the upper mold is only achieved by the hydraulic cylinder, and there is no other structure to guide it, which can easily cause the problem of offset during stamping. The cooling layer B is arranged on the lower end surface of the groove. Since the lower mold is also placed on the lower end surface of the groove, the cooling effect is greatly reduced.

[0005] Therefore, there is an urgent need for an automobile mold for automobile roof that can prevent the fan from being affected by material deformation during stamping, guide the lifting of the mold, and improve the cooling efficiency. Utility Model Content

[0006] In view of the above technical problems, the utility model provides an automobile mold for an automobile roof, which can avoid the fan being affected by material deformation during stamping, guide the lifting of the mold, and improve the cooling efficiency.

DETAILED DESCRIPTION

[0021] Example 1

[0022] The utility model provides an automobile mold for an automobile top cover, comprising a main structure, a hydraulic structure and a cooling structure.

[0023] A groove is provided on the base 11, and a support arm 12 is fixedly connected to the base 11. The inner side of the support arm 12 is fixedly connected to the guide bar 13. A through hole is provided on the support arm 12. A lower mold assembly 14 is installed on the upper end surface of the groove, and a fan assembly 17 is installed on the front and rear end surfaces of the groove. A multi-stage electric push rod 110 is installed inside the base 11. There are multiple multi-stage electric push rods 110. The moving end of the multi-stage electric push rod 110 is connected to the baffle 111. The baffle 111 can block the fan assembly 17 when it is pushed out by the multi-stage electric push rod 110. Electric push rods A15 are installed on the left and right sides of the upper end of the base 11. There are two electric push rods A15. The moving end of the electric push rod A15 is connected to the positioning plate 16. Electric push rods B18 are installed on the upper surface of the groove on the left and right sides of the lower mold assembly 14. There are multiple electric push rods B18. The moving end of the electric push rod B18 is connected to the top plate 19. The top plate 19 can move upward normally when the positioning plate 16 is retracted.

[0024] The output end of the hydraulic cylinder 21 passes through the support arm 12 and is connected to the upper mold assembly 22 .

[0025] A water pump 32 is installed at the rear end of the water tank 31. The water pump 32 is connected to a connecting pipe 38 and a transverse pipe 36. The connecting pipe 38 and the transverse pipe 36 run through the water tank 31. The connecting pipe 38 is a hose. The connecting pipe 38 is connected to the vertical pipe 34. The connection between the connecting pipe 38 and the vertical pipe 34 is connected to the positioning block 33. The vertical pipe 34 is a hard pipe. The lower end of the vertical pipe 34 extends into the upper mold assembly 22 through a through hole and is connected to the cooling pipe A35. The transverse pipe 36 is a hard pipe. The transverse pipe 36 extends into the base. One end of the transverse pipe 36 is connected to the cooling pipe B37. The cooling pipe B37 surrounds the outside of the groove in the base.

[0026] Example 2

[0027] When using the utility model, the water tank 31 and the water pump 32 are connected to the external water supply structure, and the operator places the material to be stamped on the lower die assembly 14 in the groove, and the electric push rod A15 extends to drive the positioning plate 16 to position the material. Before stamping, the baffle 111 blocks the fan assembly 17 to prevent the deformation of the material during stamping from affecting the fan assembly. The hydraulic cylinder 21 pushes the upper die assembly 22 down along the guide bar 13 to stamp the material, and the vertical pipe 34 follows the upper die assembly 22 and descends through the through hole. After the stamping is completed, the material has been stamped into a car roof product.

[0028] Due to the heat generated during the stamping process, the product needs to be cooled for easy picking and transportation. The multi-stage electric push rod 110 is shortened to retract the baffle 111 into the base 11, exposing the fan assembly 17, and the fan assembly 17 is turned on to cool the product with air. The water pump 32 is turned on to transport the water in the water tank 31 to the connecting pipe 38 and the horizontal pipe 36, and further enters the cooling pipe A35 and the cooling pipe B37 through the positioning block 33 and the vertical pipe 34 to cool the product. Since the cooling pipe A35 and the cooling pipe B37 can achieve surround cooling, they are closer to the stamped product, and reduce the problems of low cooling efficiency and energy waste caused by mold obstruction, thereby improving the cooling efficiency.

[0029] After cooling is completed, the fan assembly 17 and the water pump 32 are turned off, the multi-stage electric push rod 110 extends to push the baffle 111 to block the fan assembly 17, the electric push rod A15 shortens to retract the positioning plate 16, and the electric push rod B18 extends to lift the top plate 19, further lifting the product, and the product can be removed at this time.
