Description

Technical Field

[0001] The utility model relates to the field of cooling devices, and more specifically, to a core cooling device for an automobile wheel hub mold. Background Art

[0002] The mold is an important device in the production of automobile wheel hubs, and its cost is relatively high. During the casting process of automobile wheel hubs, if the core temperature is too high, defects such as shrinkage cavities, shrinkage porosity, and air holes will occur in the wheel hubs. Cooling the core can control the temperature of the mold, enabling the wheel hub to cool evenly during solidification and reducing the occurrence of these defects.

[0003] During the water cooling process in the core cooling device of the wheel hub mold, if the water flow in the cooling pipe is not smooth or the distribution is uneven, hot spots are likely to form in some parts. These hot spots will cause the local temperature of the object to be cooled to be too high, affecting the cooling effect and even possibly damaging the object to be cooled. Therefore, it is necessary to design a core cooling device for an automobile wheel hub mold with a water stirring function to solve the above problems. Summary of the Utility Model

The water stirring component can be used to make the water flow in the cooling water pipe produce a turbulent state, thereby improving the heat exchange efficiency and making the water flow distribution in the pipe more uniform.

[0006] 2. Technical Solution

[0008] A core cooling device for an automobile wheel hub mold includes an equipment base. A first mold is fixedly connected to the upper end of the equipment base. A second mold is arranged at the upper end of the first mold. A cooling water pipe is arranged inside the first mold. An inlet valve port is fixedly connected to the left end of the cooling water pipe. An outlet valve port is fixedly connected to the right end of the cooling water pipe. A circulation water pipe is fixedly connected between the outlet valve port and the inlet valve port. A plurality of water stirring components are fixedly connected to the inside of the cooling water pipe. Each water stirring component includes a plurality of arc-shaped small rings. The plurality of arc-shaped small rings are arranged at equal intervals in a ring shape. A spring member is fixedly connected to the outer side of the arc-shaped small ring.

[0009] Further, a refrigeration pump is fixedly connected to the upper end of the equipment base. The output end of the refrigeration pump is connected to the cooling water pipe.

[0010] Further, the spring member is connected to the inner side wall of the cooling water pipe. A pair of liquid stirring flexible sheets are fixedly connected to the rear end of the arc-shaped small ring.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] (1) In this solution, a cooling water pipe is arranged in the first mold, and the water liquid is circulated in the cooling water pipe through a refrigeration pump. The heat in the equipment is adsorbed by the water liquid. At the same time, during the circulation of the water liquid in the cooling water pipe, a water-stirring assembly can be arranged in the cooling water pipe. The water-stirring assembly can be used to make the water flow in the cooling water pipe generate a turbulent state. When the water flow is in a turbulent state, the flow path of the water is more complex, and the contact with the inner wall of the pipe and the surrounding environment is more sufficient. This enables the heat to be transferred from the object to be cooled to the water faster, thereby improving the heat exchange efficiency and making the water flow distribution in the pipe more uniform.

[0017] (2) At the same time, a plurality of liquid-stirring flexible sheets behind the arc-shaped small loop can follow the water flow and assist in agitating the water flow. During the process of the liquid-stirring flexible sheet following the water flow and agitating, the elastic small ball at the end of the liquid-stirring flexible sheet can be in contact with the cooling water pipe inside the elastic inner surface. When the elastic small ball contacts the cooling water pipe, a rebounding force can be generated, making the liquid-stirring flexible sheet follow the water flow in the cooling water pipe more frequently, and performing turbulent impact treatment on the water liquid in the cooling water pipe.
