Description

Technical Field

[0001] The utility model belongs to the technical field of casting wheel hub molds, and particularly relates to a water-cooled sticker plate cooling structure. Background Art

[0002] As one of the most important moving parts of an automobile, the wheel hub has high requirements for its performance, weight and service life. The wheel hub processed by low-pressure casting needs to use a mold. The low-pressure casting mold for the wheel hub usually includes a side mold, an upper mold and a lower mold. Four side molds distributed in a circumferential array cooperate with the upper mold and the lower mold to enclose a wheel hub casting cavity. After the wheel hub is cast by the wheel hub casting mold, the wheel hub needs to be cooled for rapid forming.

[0003] Currently, as Figure 1 shown, the cooling method of the side mold has gradually changed from the original air cooling to water cooling, which improves the cooling efficiency of the side mold. The side mold usually adopts a cooling structure with a circulating pipeline installed, and the opened cooling water is introduced into the circulating pipeline to cool the cavity. However, this method has certain drawbacks. The entire circular ring structure is extremely prone to deformation when heated, resulting in poor close fit with the lower mold of the cooling body, and the cooling effect is poor. Moreover, the circular water channel is basically one-in and one-out in a circle, and the temperature difference between the water inlet and the water outlet is relatively large, which easily makes the cooling part uneven, thus affecting the cooling speed and effect. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water-cooled sticker plate cooling structure to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water-cooled sticker plate cooling structure, comprising:

[0006] A base, a triangular column is provided on the top of the base, a lower mold is provided in the base, an upper mold is provided on the top of the lower mold, a side mold is provided on the surface of the upper mold, a connecting plate is connected to the top of the upper mold, a cold sticker plate assembly is provided in the base and at the bottom of the lower mold, and water inlet pipes and water outlet pipes are connected to the surfaces of multiple water-cooled sticker plates of the cold sticker plate assembly. The water inlet pipes and the water outlet pipes are respectively connected to the circular water inlet pipes and the circular water outlet pipes on the surfaces of the water-cooled sticker plates, so that each water-cooled sticker plate can be cooled separately.

[0007] Preferably, the cold sticker plate assembly includes a short pipe, and the water inlet pipe and the water outlet pipe are respectively connected to the circular water inlet pipe and the circular water outlet pipe through the short pipe.

[0008] Preferably, water inlet joints and water outlet joints are respectively connected to the surfaces of the circular water inlet pipe and the circular water outlet pipe.

[0009] Preferably, a gate is provided at the center of the bottom of the base, and an ejector plate is connected to the top of the connecting plate through guide posts.

[0010] Preferably, an ejector pressure plate is connected to the top of the ejector plate, and a connecting column is connected to one end of the top of the ejector pressure plate.

[0011] Preferably, two sets of ejector rods are provided at the bottom of the ejector pressure plate, and one end of the ejector rods is connected to the upper die.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: After the upper die, the lower die, and the side die are clamped together to form a closed cavity, molten aluminum at about 700 degrees is injected into the cavity of the lower die from the central gate under pressure. Then, when it is necessary to cool down the molten aluminum in the cavity, multiple water-cooling pads are arranged in a circular shape at the bottom of the lower die and tightly locked with the lower die. By connecting the water inlet pipe and the water outlet pipe on the surface of the water-cooling pads to the circular water inlet pipe and the circular water outlet pipe respectively, and connecting the water inlet joint and the water outlet joint to the external cooling circulating water pipe, the cooling circulating water enters the circular water inlet pipe through the water inlet joint. The cooling water in the circular water inlet pipe flows into the water inlet pipe through the short pipe and then into the water-cooling pads through the water inlet pipe, so that cooling water can be introduced into the multiple water-cooling pads to cool down the cavity. The cooling water that absorbs heat in the water-cooling pads can flow into the circular water outlet pipe through the short pipe, and the cooling water that absorbs heat in the circular water outlet pipe flows back into the external cooling circulating water pipe through the water outlet joint for refrigeration, thus completing the entire cycle cooling. By connecting each water-cooling pad separately to the circular water inlet pipe and the circular water outlet pipe, individual cooling can be achieved. Moreover, for the thicker part at the tail of the spoke of the cast wheel hub product, this structure can quickly take away the heat of each spoke and cool it down rapidly, enabling each spoke to be cooled more evenly, greatly shortening the casting cooling cycle of the product, and thus significantly improving the cooling speed and effect.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] The present invention provides a water-cooled disc cooling structure as shown in Figures 2 - 4 and includes:

[0020] Base 1, a triangular column 2 is provided on the top of the base 1, a lower die 3 is provided in the base 1 and an upper die 4 is provided on the top of the lower die 3, a side die 5 is provided on the surface of the upper die 4, a connecting plate 6 is connected to the top of the upper die 4, a cold disc assembly is provided in the base 1 and at the bottom of the lower die 3, and water inlet pipes 8 and water outlet pipes 9 are connected to the surfaces of multiple groups of water-cooled discs 7 of the cold disc assembly. The water inlet pipes 8 and the water outlet pipes 9 are respectively connected to the circular water inlet pipes 10 and the circular water outlet pipes 11 on the surfaces of the water-cooled discs 7, so that each water-cooled disc 7 can be cooled separately.

[0021] The cold disc assembly includes a short pipe 12, and the water inlet pipes 8 and the water outlet pipes 9 are respectively connected to the circular water inlet pipes 10 and the circular water outlet pipes 11 through the short pipe 12.

[0022] Water inlet joints 13 and water outlet joints 14 are respectively connected to the surfaces of the circular water inlet pipes 10 and the circular water outlet pipes 11.

[0023] A gate 15 is provided at the center of the bottom of the base 1, and an ejector plate 17 is connected to the top of the connecting plate 6 through a guide post 16. The guide post 16 can guide the moving direction of the upper die 4 and enhance the stability of the movement of the upper die 4.

[0024] An ejector pressure plate 18 is connected to the top of the ejector plate 17, and a connecting column 19 is connected to one end of the top of the ejector pressure plate 18.

[0025] Two groups of ejector rods 20 are provided at the bottom of the ejector pressure plate 18, and one end of the ejector rods 20 is connected to the upper die 4. The ejector rods 20 drive the upper die 4 to move and form a closed cavity after being combined with the lower die 3.

[0026] For this water-cooled patch plate cooling structure, after the upper die 4, lower die 3, and side die 5 are combined to form a closed cavity, molten aluminum at about 700 degrees is injected into the cavity of the lower die 3 from the central gate 15 under pressure. Then, when it is necessary to cool down the molten aluminum in the cavity, multiple water-cooled patch plates 7 are arranged in a circle at the bottom of the lower die 3 and tightly locked with the lower die 3. A layer of graphite heat-conducting gasket is added in the middle, which can effectively achieve surface contact cooling;

The cooling water in the circular water inlet pipe 10 flows into the water inlet pipe through the short pipe 12 and flows into the water-cooled patch plate 7 through the water inlet pipe 8, so that cooling water can be introduced into multiple water-cooled patch plates 7 to cool down the cavity. The cooling water that has absorbed heat in the water-cooled patch plate 7 can flow into the circular water outlet pipe 11 through the short pipe 12 at the water outlet pipe 9, and the cooling water that has absorbed heat in the circular water outlet pipe 11 flows back into the external cooling circulating water pipe through the water outlet joint 14 for refrigeration, thus completing the entire cycle cooling. By connecting each water-cooled patch plate 7 separately to the circular water inlet pipe 10 and the circular water outlet pipe 11, separate cooling can be achieved;

[0028] Moreover, for the thicker part at the tail of the spoke of the cast wheel hub product, this structure can quickly take away the heat of each spoke and cool it down rapidly, enabling each spoke to be cooled more evenly, greatly shortening the casting cooling cycle of the product, and thus significantly improving the cooling speed and effect.
