[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In one typical implementation of this application, please refer to Figures 1-5 As shown, an injection mold with a cooling mechanism includes: a base 1, a lower mold 2 fixedly mounted on the top surface of the base 1, an upper mold 3 disposed above the lower mold 2, the lower mold 2 and the upper mold 3 cooperating with each other, a cooling pipe 13 disposed inside the base 1, and a cooling assembly disposed on the side wall of the base 1, the cooling assembly including:

[0024] The housing 4 is fixedly installed on the right side wall of the base 1. A partition 5 is fixedly installed on the inner wall of the housing 4. A baffle 6 is fixedly installed at the center of the top surface of the partition 5. The partition 5 and the baffle 6 divide the interior of the housing 4 into three areas. A temperature sensor is installed in the area below the baffle 6.

[0025] As a preferred embodiment of this example, please refer to [link / reference]. Figure 3 and Figure 4 As shown, the cooling assembly also includes two top plates 7, which are fixedly installed on the two side walls of the baffle 6 respectively. An electric heater 8 and a cooler 9 are fixedly installed on the top surface of the two top plates 7 respectively. The cooling assembly also includes two sets of switches, which are respectively installed on the two top plates 7.

[0026] Based on the above features, the temperature of the coolant can be dynamically adjusted according to the cooling requirements of different areas of the injection molded part. Specifically, when the temperature sensor detects the temperature of the coolant in the area below the baffle 5, if the operator finds that the coolant below the baffle 5 does not meet the cooling requirements of the injection molded part, the switch can be turned on or off as needed via the controller. This will activate the electric heater 8 and the cooler 9 to heat or cool the coolant in the areas on both sides of the baffle 6. Afterward, the switch can be turned on again to allow the coolant to flow into the area below the baffle 5, thus achieving dynamic adjustment.

[0027] As a preferred embodiment of this example, please refer to [link / reference]. Figure 3 and Figure 5 As shown, the switch includes: an electric actuator 11, which is fixedly installed on the top surface of the top plate 7. The output end of the electric actuator 11 extends through the top surface of the top plate 7 to the bottom of the top plate 7. A sealing plate 12 is fixedly installed on the output shaft of the electric actuator 11. Two leakage holes 10 are opened on the top surface of the partition 5, and the two leakage holes 10 are located on both sides of the baffle 6.

[0028] Based on the above features, the coolant in the areas on both sides of the baffle 6 can flow into the area below the partition 5. Specifically, when it is necessary to allow the coolant in the areas on both sides of the baffle 6 to flow into the area below the partition 5, the operator uses the controller to activate the electric actuator 11. When the electric actuator 11 retracts, the coolant in the areas on both sides of the baffle 6 flows into the area below the partition 5 through the drain hole 10. If it is necessary to allow the coolant to flow into the area below the partition 5, the electric actuator 11 can be extended to seal the drain hole 10 with the sealing plate 12.

[0029] As a preferred embodiment of this example, please refer to [link / reference]. Figure 2 and Figure 4 As shown, a micro pump 14 is fixedly installed on the side wall of the housing 4, and a first pipe 15 and a second pipe 16 are respectively provided on both sides of the micro pump 14.

[0030] As a preferred embodiment of this example, please refer to [link / reference]. Figure 2 and Figure 3 As shown, one end of the first pipe 15 is connected to the area below the partition 5, and one end of the second pipe 16 is connected to the cooling pipe 13.

[0031] As a preferred embodiment of this example, please refer to [link / reference]. Figure 2 and Figure 3 As shown, the side walls of the housing 4 and the base 1 are provided with two return pipes 17, which allow the coolant in the cooling pipe 13 to flow into the areas on both sides of the baffle 6.

[0032] Based on the above features, the coolant in the area below the partition 5 can flow into the cooling pipe 13 to cool the lower mold 2. Specifically, the operator opens the first pipe 15 through the controller, so that the coolant in the area below the partition 5 flows into the cooling pipe 13 through the first pipe 15 and the second pipe 16, and then flows back to the area on both sides of the baffle 6 through the return pipe 17.

[0033] Working principle:

[0034] In use, the housing 4 is fixedly installed on the right side wall of the base 1. The interior of the housing 4 is divided into three areas by a partition 5 and a baffle 6. The baffle 6, fixedly installed at the center of the top surface of the partition 5, divides the internal space of the housing 4 into left and right side areas and a lower area. A temperature sensor is installed in the lower area to monitor the temperature of the coolant. When the injection molded part requires cooling in a specific area, the system dynamically adjusts based on the feedback from the temperature sensor. Specifically, if the temperature sensor detects that the coolant temperature in the lower area of ​​the partition 5 does not meet the cooling requirements of the injection molded part, the operator can control the working status of the electric heater 8 and the cooler 9 by operating two sets of switches through the controller. These two devices are respectively installed on the top plates 7 on both sides of the baffle 6. By opening or closing the switches, the coolant in the areas on both sides of the baffle 6 can be heated or cooled respectively. Each switch includes an electric actuator 11, which is fixedly installed on the top surface of the top plate 7. Its output end extends through the top plate 7 to the bottom and is fixedly connected to a sealing plate 12. Two drainage holes 10 are opened on the top surface of the partition 5, located on both sides of the baffle 6. When it is necessary for the cooled liquid, which has undergone heating or cooling treatment on both sides of the baffle 6, to flow into the area below the partition 5, the operator retracts the electric push rod 11 via the controller, and the sealing plate 12 moves accordingly, allowing the coolant to flow into the area below through the drain hole 10. Conversely, when it is not necessary for coolant to flow in, the electric push rod 11 extends, and the sealing plate 12 blocks the drain hole 10. In addition, a micro pump 14 is fixedly installed on the side wall of the housing 4, with a first pipe 15 and a second pipe 16 connected to its two sides respectively. One end of the first pipe 15 is connected to the area below the partition 5, while one end of the second pipe 16 is connected to the cooling pipe 13, which is used to directly cool the lower mold 2 of the injection mold. By opening the first pipe 15 via the controller, the coolant in the area below the partition 5 is pumped by the micro pump 14, and sequentially enters the cooling pipe 13 through the first pipe 15 and the second pipe 16 to cool the lower mold 2. Subsequently, the coolant flows back to the areas on both sides of the baffle 6 through two return pipes 17, forming a complete coolant circulation loop.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
