[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] like Figures 1-3 As shown, an injection mold for easy temperature control includes a fixed mold base, which is composed of a first fixed mold assembly 1 and a second fixed mold assembly 2. The first fixed mold assembly 1 and the second fixed mold assembly 2 are combined to form a mold groove 3. An annular groove 4 is provided on the relatively close side of the first fixed mold assembly 1 and the second fixed mold assembly 2. Two pistons 6 are slidably connected to the inner wall of the annular groove 4. A sealing ring 7 is fixedly connected to the outer wall of each piston 6. The sealing ring 7 is in slidable contact with the inner wall of the annular groove 4. Two limiting rings 5 ​​are fixedly connected to the inner wall of the annular groove 4. Connecting pipes 8 are fixedly connected to both sides of the fixed mold base. The ends of the connecting pipes 8 extend into the interior of the annular groove 4 and extend into the inner wall of the limiting rings 5 ​​and are fixedly connected to them.

[0022] like Figure 2 As shown, a mounting base 12 is fixedly connected to the bottom of the first fixed mold assembly 1, and a water pump 9 is fixedly connected to the top of the mounting base 12. The port of the water pump 9 is fixedly connected to one of the connecting pipes 8, and a water suction pipe 10 is fixedly connected to the port of the water pump 9. An extension pipe 11 is fixedly connected to the outer wall of the other connecting pipe 8. Driven by the water pump 9, the cooling water can circulate in the annular groove 4 to effectively cool the mold. The cooling water can quickly remove the heat generated by the mold during the injection molding process, maintain the constant temperature of the mold, and help improve the molding quality and production efficiency of the injection molded parts.

[0023] like Figure 1 As shown, a base 13 is provided below the mounting base 12, and two support plates 14 are fixedly connected to the top of the base 13. The ends of the support plates 14 are fixedly connected to the mounting base 12 respectively.

[0024] like Figure 1 and Figure 2As shown, the outer wall of the support plate 14 is provided with a reserved groove 15. The end of the water pumping pipe 10 passes through one of the reserved grooves 15 and extends to the bottom of the mounting base 12. The end of the extension pipe 11 passes through the other reserved groove 15 and extends to the bottom of the mounting base 12.

[0025] like Figure 4 As shown, a support base 16 is fixedly connected to the top of the base 13, and a water tank 17 is fixedly connected to the top of the support base 16.

[0026] like Figure 4 As shown, a water tank 17 has a water trough 19 on its top. Two partitions 21 are fixedly connected to the inner wall of the water trough 19, and an insulation layer 20 is fixedly connected between the two partitions 21. A heater 18 is fixedly connected to the outer wall of the water tank 17. The end of the water pump pipe 10 is fixedly connected to the water tank 17, and the end of the extension pipe 11 is fixedly connected to the water tank 17. The water tank 17 is equipped with a water trough 19 and partitions 21, and the space between the partitions 21 is filled with an insulation layer 20, which can effectively reduce heat loss and improve the heating efficiency of the heater 18.

[0027] Working principle: The water inside the water tank 17 is heated by the heater 18. During the product processing, the water pump 9 injects the hot water inside the water tank 17 into the annular groove 4 through the connecting pipe 8, thereby quickly heating the fixed mold base and rapidly raising the fixed mold base to a suitable working temperature to ensure the quality of the processed product.

[0028] During the hot water injection process, pressure is generated inside the annular groove 4, which pushes the two pistons 6 to both sides of the limiting ring 5 at the other end;

[0029] During the demolding process, the water pump 9 discharges the water inside the annular groove 4 into the water tank 17 through the water pumping pipe 10. At this time, the annular groove 4 generates suction, which quickly pulls the piston 6 to the other side. At this time, the coolant inside the water tank 17 quickly enters the annular groove 4, thereby quickly cooling the fixed mold base.

[0030] By installing partitions 21 inside the water tank 19 and installing insulation layers 20 between the partitions 21, the mutual influence between hot and cold water can be avoided, which would cause heat loss and increase energy consumption.
