They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0022] like Figures 2-4 As shown, this embodiment discloses a water-cooled mold, including an upper mold 10, a lower mold 20 and a water circulation device 30. The upper mold 10 and the lower mold 20 are combined to form at least one cavity 11. The upper mold 10 is provided with a first cooling channel 12 surrounding the cavity 11, and the lower mold 20 is provided with a second cooling channel 21 surrounding the cavity 11. The first cooling channel 12 and the second cooling channel 21 are connected after the mold is combined. The water circulation device 30 includes a water storage container 31, a water inlet pipe 32, a return pipe 33 and a water Pump 34, the drain outlet of the water storage container 31 is connected to the first cooling channel 12 through the water inlet pipe 32, and the second cooling channel 21 is connected to the water inlet of the water storage container 31 through the return pipe 33. The water pump 34 is used to transport the water in the return pipe 33 to the water inlet of the water storage container 31. A boosting pipe 41 is connected in parallel to the water inlet pipe 32, and a plurality of deformable boosting containers 42 are detachably connected to the boosting pipe 41. The lowest liquid level height of the inner cavity of the boosting container 42 is higher than the first cooling channel 12.

[0023] The water-cooled mold of this embodiment is provided with a first cooling channel 12 surrounding the cavity 11 in the upper mold 10, and a second cooling channel 21 surrounding the cavity 11 in the lower mold 20. The first cooling channel 12 and the second cooling channel 21 are connected after the mold is closed. After the injection molding is completed, cold water is introduced into the water inlet end of the first cooling channel 12, and the cold water then passes through the second cooling channel 21. The cold water is used to quickly cool the product in the cavity 11, thereby improving production efficiency.

[0024] In addition, a water circulation device 30 is also provided, which includes a water storage container 31, a water inlet pipe 32, a return pipe 33 and a water pump 34. The drain outlet of the water storage container 31 is connected to the first cooling channel 12 through the water inlet pipe 32, and the second cooling channel 21 is connected to the water inlet of the water storage container 31 through the return pipe 33. The water pump 34 is used to transport the water in the return pipe 33 to the water inlet of the water storage container 31. The lowest liquid level height of the water storage container 31 is higher than the first cooling channel 12. The height difference is utilized to increase the water pressure entering the first cooling channel 12 and the second cooling channel 21, thereby increasing the water flow rate, accelerating the cooling efficiency, and thus improving production efficiency.

[0025] Furthermore, the maximum liquid level height of the water storage container 31 of this embodiment is higher than the maximum liquid level height of the inner cavity of the boosting container 42. When the water storage container 31 is filled with water, the water is transported to the boosting container 42 through the water inlet pipe 32, and can fill the boosting container 42, so as to facilitate the subsequent pressurization of the first cooling channel 12 and the second cooling channel 21 by the boosting container 42.

[0026] Furthermore, in order to facilitate the disassembly and assembly of the pressurized container 42 , in this embodiment, a mounting portion 421 is connected to the bottom of the pressurized container 42 , and the mounting portion 421 is threadedly connected to the pressurized pipe 41 .

[0027] Furthermore, the pressurized container 42 is a plastic bottle, which is widely available and inexpensive. After water is filled into the inner cavity of the plastic bottle, the plastic bottle deforms and swells, and the water fills the inner cavity of the plastic bottle. During circulating cooling, due to the addition of the plastic bottle, the water in the plastic bottle is used to pressurize the first cooling channel 12 and the second cooling channel 21, thereby increasing the flow rate of the water.

[0028] Please refer to Figure 2 and Figure 3 In this embodiment, the first cooling channel 12 and the second cooling channel 21 are connected through a connecting structure. The connecting structure includes a socket 51 located on the lower side of one end of the first cooling channel 12 and a protrusion 52 connected to the upper side of one end of the second cooling channel 21. The protrusion 52 and the socket 51 are vertically plugged into each other. After the upper mold 10 and the lower mold 20 are closed, the protrusion 52 and the socket 51 can be aligned and combined to avoid deviation, thereby realizing the connection between the first cooling channel 12 and the second cooling channel 21.

[0029] Furthermore, a waterproof sealing ring 53 is provided on the outer side of the protrusion 52 of this embodiment, thereby improving the sealing effect of the connection position and preventing water leakage.

[0030] Furthermore, a fan 60 is provided above the water storage container 31 of this embodiment, with an air outlet of the fan 60 facing the water storage container 31 , so that the fan 60 is used to cool the water in the water storage container 31 .

[0031] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention.
