Specific embodiments

[0019] The following further describes the present utility model in detail with reference to the drawings and specific embodiments. The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limiting the present utility model to the disclosed form.

The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0020] Embodiment:

[0021] Please refer to Figures 1-6 , the present utility model provides a technical solution: a mold for disc brake hub casting, including a base 1, a lower die 2 slidably connected to the top of the base 1, and an upper die 3 slidably connected to the top of the lower die 2; a cooling device 4, the outside of the cooling device 4 is fixedly connected to the inside of the base 1, and the cooling device 4 is used to cool the mold;

[0022] The cooling device 4 includes a water tank 41, the bottom of the water tank 41 is fixedly connected to the bottom of the inner cavity of the base 1, a water pipe 42 is fixedly connected to the outside of the water tank 41, one end of the water pipe 42 away from the water tank 41 is fixedly connected to a heat dissipation device 43, and the bottom of the heat dissipation device 43 is fixedly connected to the outside of the water tank 41 through a pipeline; a stripping device 5, the outside of the stripping device 5 is slidably connected to the outside of the upper die 3, and the stripping device 5 is used to eject the upper die 3 from the mold clamping surface;

[0023] During casting, the lower mold 2 is fixed on the base 1, and the bottom of the upper mold 3 is slidably connected to the top of the lower mold 2. The product is cooled and formed between the upper mold 3 and the lower mold 2. The water pump inside the water tank 41 drives the cold water to flow to the water pipe 42. The cold water flows along the water pipe 42 to the mold. The cold water takes away part of the heat of the mold through heat exchange, which speeds up the cooling speed of the product. The water flows along the water pipe 42 to the inside of the heat sink 43. After being cooled by the heat sink 43, it flows back to the inside of the water tank 41 along the heat sink 43. After the product is cooled, the stripping device 5 drives the upper mold 3 to move downward, so that the upper mold 3 and the lower mold 2 are separated.

[0024] By setting up a cooling device 4, the mold is cooled, and the heat loss of the mold is accelerated by water flow, and the water flow is recycled to save water. By setting up a stripping device 5, after the product is cooled, the mold is separated to facilitate product demoulding and avoid mold adhesion, which affects product demoulding.

[0025] A fan 7 is fixedly installed on the inner side of the base 1, and a ventilation hole 6 is opened in the wall of the base 1. When in use, the fan 7 drives the air flow, and the air flow enters the base 1 along the ventilation hole 6. The air flow passes through the cooling device 4 and flows out from the ventilation hole 6 on the other side of the base 1. The flow of air accelerates the cooling speed of the mold and assists the cooling device 4 in heat dissipation.

[0026] The heat dissipation device 43 includes a shell 431, the top of the shell 431 is fixedly connected to the bottom end of the water pipe 42, the inner side of the shell 431 is fixedly connected to a slow flow plate 432, the outer side of the shell 431 is fixedly connected to a heat sink 433, and the bottom of the shell 431 is fixedly connected to the outer side of the water tank 41 through a pipeline. When in use, water flows downward along the water pipe 42 to the inside of the shell 431, and the water flows along the shell 431 to the slow flow plate 432. The slow flow plate 432 blocks the water flow, reduces the flow rate of the water flow, and prolongs the time the water flow stays in the shell 431. The water flows downward along the slow flow plate 432. After the water flow exchanges heat with the mold, the temperature of the water flow is relatively high, and the heat of the water flow is dissipated into the outside air. The heat sink 433 expands the contact area between the outside and the water flow, and enhances the heat dissipation capacity of the water flow. The water flow flows downward along the shell 431 back to the inside of the water tank 41. By setting up the heat dissipation device 43, the heat dissipation speed of the water flow is accelerated, the temperature of the mold is lowered by the water flow, and then the heat dissipation speed of the water flow is accelerated by the heat dissipation device 43. The water flow is recycled, and the mold is cooled while reducing the amount of water used.

[0027] The stripping device 5 includes a telescopic cylinder 51. The outer side of the telescopic cylinder 51 is fixedly connected to both sides of the base 1. The top of the telescopic cylinder 51 is fixedly connected with a tray 52. The outer side of the upper mold 3 is fixedly connected with a connecting plate 53. The bottom of the connecting plate 53 is slidably connected to the top of the tray 52. A blank holding device 54 is fixedly installed on the outer side of the lower mold 2. After casting is completed, the telescopic cylinder 51 drives the tray 52 to move upward. The tray 52 drives the connecting plate 53 to move downward. The connecting plate 53 drives the upper mold 3 to move upward. The blank holding device 54 presses the lower mold 2, and the upper mold 3 and the lower mold 2 are separated. At this time, the product is unloaded from the mold. By setting the stripping device 5, after casting is completed, the upper mold 3 and the lower mold 2 are separated, making it easy for the mold to be demolded without manual operation, reducing the labor intensity of the staff, avoiding mold adhesion, and facilitating the worker to demold the product.

[0028] The blank holding device 54 includes a pressing plate 542. The outer side of the lower mold 2 is fixedly connected with a fixing plate 541. The top of the fixing plate 541 is slidably connected to the bottom of the pressing plate 542. Both ends of the pressing plate 542 are slidably connected with threaded rods 543. A threaded hole 544 is formed in the wall of the base 1. The inner side of the threaded hole 544 is slidably connected to the outer side of the threaded rod 543. When in use, the lower mold 2 is installed on the base 1. The pressing plate 542 presses the fixing plate 541. The threaded rod 543 passes through the pressing plate 542 and extends into the threaded hole 544. The threaded rod 543 is fixed by the threaded hole 544. The threaded rod 543 fixes the pressing plate 542. The pressing plate 542 fixes the fixing plate 541. The fixing plate 541 fixes the lower mold 2. By fixing the lower mold 2 with the blank holding device 54, the movement of the lower mold 2 is prevented, facilitating the disassembly of the lower mold 2.

[0029] Working principle:

[0030] When in use, the lower mold 2 is installed on the base 1. The pressing plate 542 presses the fixing plate 541. The threaded rod 543 passes through the pressing plate 542 and extends into the threaded hole 544. The threaded rod 543 is fixed by the threaded hole 544. The threaded rod 543 fixes the pressing plate 542. The pressing plate 542 fixes the fixing plate 541. The fixing plate 541 fixes the lower mold 2. The bottom of the lower mold 2 is in contact with the outer side of the water pipe 42. The upper mold 3 and the lower mold 2 are pressed together by an external driving mechanism, and the raw material is filled between the upper mold 3 and the lower mold 2;

[0031] During casting, the water pump inside the water tank 41 drives the cold water to flow to the water pipe 42, and the cold water flows along the water pipe 42 to the mold. The cold water takes away part of the heat of the mold through heat exchange, thereby accelerating the cooling speed of the product. The water flows downward along the water pipe 42 to the inside of the shell 431, and the water flows along the shell 431 to the slow flow plate 432. The slow flow plate 432 blocks the water flow, reduces the flow rate of the water flow, and prolongs the time the water flow stays in the shell 431. In the process of the water flow flowing downward along the slow flow plate 432, the temperature of the water flow is higher after the water flow exchanges heat with the mold, and the heat of the water flow is dissipated to the outside air. The heat sink 433 expands the contact area between the outside and the water flow, thereby enhancing the heat dissipation capacity of the water flow. The water flow flows downward along the shell 431 back to the inside of the water tank 41, and the water flow is recycled, thereby saving water resources.

[0032] After the casting is completed, the telescopic cylinder 51 drives the tray 52 to move downward, the tray 52 drives the connecting plate 53 to move upward, the connecting plate 53 drives the upper mold 3 to move upward, the pressing device 54 presses the lower mold 2, and the upper mold 3 and the lower mold 2 are separated. At this time, the product can be unloaded from the mold.

[0033] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
