[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0033] Combine the following Figures 1 to 5A splitter cone of a die-casting mold according to an embodiment of the utility model is described in detail.

[0034] like Figures 1 to 5 As shown, a diverter cone of a die-casting mold according to an embodiment of the utility model includes: a diverter cone body 102, a water-blocking sleeve 104, a diverter sleeve 106, a pressure plate 114, etc. The water-blocking sleeve 104 is installed in the cavity of the diverter cone body 102, the diverter sleeve 106 is sleeved in the water-blocking sleeve 104, and is fixedly connected to the diverter cone body 102 by bolts 108, the water-blocking sleeve 104 and the diverter sleeve 106 cooperate with each other to form a cooling cavity 110, and the cooling cavity 110 is connected to the cooling water channel 112 set in the diverter cone body 102, so as to realize cooling of the aluminum liquid by the circulation of cooling water. The pressure plate 114 is covered on the diverter cone body 102, and the diverter sleeve 106 is covered inside. Therefore, it is possible to effectively avoid the phenomenon of mold leakage caused by early cracking without affecting heat conduction, effectively avoid the phenomenon of batch scrapping of products, and help improve product quality. The service life cycle of the diverter cone of the die-casting mold has been significantly improved and can be used throughout the life cycle of the mold, which is conducive to reducing the cost of using the diverter cone and thus reducing production costs.

[0035] It is worth noting that the specific structures of the diverter cone body 102, the water-blocking sleeve 104, the diverter sleeve 106, and the pressing plate 114 can be slightly adjusted to suit the product type and the mold structure design. The water-blocking sleeve 104 can be made of steel or copper.

[0036] Furthermore, water glycol or silver silicone grease is filled between the diverter cone body 102 and the water-isolating sleeve 104. Thus, the heat conduction efficiency between the water-isolating sleeve 104 and the diverter cone body 102 can be effectively guaranteed, thereby ensuring the cooling effect of the diverter cone on the aluminum liquid. Other silicone grease-based heat-conducting media can also be used.

[0037] Furthermore, if Figures 3 to 5 As shown, a primary sealing ring 116 is arranged between the diverter cone body 102 and the water-blocking sleeve 104. The primary sealing ring 116 is compressed and sealed by the water-blocking sleeve 104, thereby effectively preventing the cooling water inside the diverter cone from leaking from the front end into the "mold cavity side" and mixing with the aluminum liquid, making it less likely for the mold to leak.

[0038] Furthermore, if Figures 3 to 5 As shown, a secondary sealing ring 118 is provided between the water-blocking sleeve 104 and the diverter sleeve 106, and the secondary sealing ring 118 is pressed and sealed by the diverter sleeve 106. A tertiary sealing ring 120 is provided between the diverter cone body 102 and the pressing plate 114, and the tertiary sealing ring 120 is pressed and sealed by the pressing plate 114. Therefore, the sealing structure can effectively prevent cooling water from leaking from the "mold core side", and mold water leakage is not likely to occur.

[0039] Furthermore, if Figures 3 to 5 As shown, the water blocking sleeve 104 is T-shaped with a cavity therein, and a through hole 1042 communicating with the cavity is provided at the wider end, which is convenient for installation and for communicating with the cooling water channel 112.

[0040] Furthermore, if Figures 3 to 5 As shown, the flow divider sleeve 106 is T-shaped and is placed in the cavity of the water-blocking sleeve 104, which is convenient for installation to form the cooling cavity 110 and ensure the cooling effect.

[0041] Furthermore, if Figure 4 As shown, when the flow dividing sleeve 106 and the water blocking sleeve 104 are installed in the cavity of the flow dividing cone body 102, the inner end thereof is tilted downward, thereby further ensuring the cooling effect of the flow dividing cone on the aluminum liquid.
