Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to a split cone double-point cooling mould. Background Art

[0002] Aluminum alloy parts for automobiles are formed by high-pressure die casting, which is fast, efficient and low-cost. High-pressure casting is a casting method that pours molten alloy liquid into a pressure chamber, fills the cavity of a steel mold at high speed, and solidifies the alloy liquid under pressure to form a casting. In order to improve production efficiency and quickly cool the product out of the mold, it is necessary to increase the cooling water to quickly cool the thick and large parts of the casting. This thick and large part is called the handle to avoid the risk of explosion caused by insufficient cooling, that is, the thick part of the casting handle is not cooled sufficiently, and the surface solidifies before the internal part has time to solidify before it leaves the mold. The internal aluminum liquid instantly breaks through the surface under pressure and explodes. In order to improve the cooling and cooling effect of the mold, the traditional split cone double-point cooling mold is equipped with a super-cold water core and a cooling water channel in the bottom mold, and the die casting is cooled and formed by two coolants. However, the above common types of cooling molds have the following problems in actual applications:

[0003] Due to product structural reasons, a super-cold water core needs to be set at the corresponding position below the diverter cone, which interferes with the cooling water of the diverter cone. The diverter cone cannot be cooled or the super-cold water core needs to be cancelled, and the overall cooling effect is poor. Utility Model Content

[0004] The utility model aims to provide a splitter cone double-point cooling mold to solve the problem that the splitter cone of the existing splitter cone double-point cooling mold proposed in the above background technology cannot be cooled or the super-cooled water core needs to be cancelled.

[0006] Preferably, solenoid valves are fixedly installed in the middle of the cooling water discharge pipe and the middle of the cooling water inlet pipe, and pipe joints are fixedly installed at one end of the cooling water discharge pipe and one end of the cooling water inlet pipe; installation and use are convenient.

[0007] Preferably, the diversion assembly includes a pad and a water-blocking plate fixedly arranged on the top of the pad; the flow path of the cooling water can be increased, thereby saving cooling water.

[0008] Preferably, the inner diameter of the first cooling water column is larger than the inner diameter of the second cooling water column; the heat exchange effect is significant.

[0009] Preferably, the super-cold water core assembly includes a bent tube and a super-cold water inlet pipe fixedly connected to one end of the bent tube, the other end of the bent tube is fixedly connected to a super-cold water discharge pipe, one end of the super-cold water inlet pipe and one end of the super-cold water discharge pipe both extend out of the base and are fixedly provided with connecting flanges; the heat exchange cooling rate is fast and the molding is efficient.

[0010] Preferably, mounting seats are fixedly provided on both sides of the base, and reserved locking holes are provided on the surfaces of the two mounting seats, so as to facilitate the installation and use of the mold.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The diverter cone double-point cooling mold optimizes the water channel structure inside the traditional mold, extends the cooling water flow path, and cleverly avoids the core with super-cold water under the diverter cone, ensuring that the diverter cone cooling is not affected. The cooling effect is significantly improved. The diverter cone cooling adopts a double-point cooling structure to make up for the defects of the die-casting process caused by product structure problems, which is conducive to improving production efficiency and making die-casting safer and more efficient.

The cooling water inlet pipe 4 and the cooling water discharge pipe 5 are respectively connected to the cooling water system of the die-casting machine. The super-cold water core assembly 3 is connected to the super-cold water circulation system of the die-casting machine. The die-casting machine presses the upper mold onto the conical bottom mold 2. After injecting the molten alloy, the cooling water enters the second cooling water column 12 through the cooling water inlet pipe 4. After circulation and heat exchange, it enters the first cooling water column 11 through the connecting channel 15. After carrying heat, it is discharged from the base 1 through the cooling water discharge pipe 5, thereby realizing the cooling and molding of the die-cast product.

[0021] See also Figure 1 and Figure 4 Furthermore, a solenoid valve 6 is fixedly installed in the middle of the cooling water discharge pipe 5 and the middle of the cooling water inlet pipe 4, and a pipe joint 7 is fixedly installed at one end of the cooling water discharge pipe 5 and one end of the cooling water inlet pipe 4;

[0024] When in use, when the cooling water enters the first cooling water column 11 and the second cooling water column 12, it will flow along the baffle plate 14. The deflection of the baffle plate 14 can increase the flow path of the cooling water in the conical bottom mold 2, thereby increasing the heat exchange effect and saving cooling water.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 Further, the supercooled water core assembly 3 includes a bending tube 31 and a supercooled water inlet pipe 33 fixedly connected to one end of the bending tube 31, and the other end of the bending tube 31 is fixedly connected to a supercooled water discharge pipe 32, and one end of the supercooled water inlet pipe 33 and one end of the supercooled water discharge pipe 32 extend out of the base 1 and are fixedly provided with a connecting flange 34;

At the same time, the core with super-cold water under the diversion cone is cleverly avoided.
