[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 The utility model provides a technical solution: a water-cooled integrated hot and cold mold temperature control unit, including an equipment cabinet 1, a water tank 2, a refrigeration unit 3 and a heating unit 4, wherein the water tank 2, the refrigeration unit 3 and the heating unit 4 are all fixedly installed inside the equipment cabinet 1. Specifically, cold water is stored in the water tank 2, the refrigeration unit 3 can transport cold water to the mold, and can actively cool down the refluxed hot water, the heating unit 4 can heat the cold water in the water tank 2 to the required temperature and then transport it to the mold, and a part of the hot water refluxed from the mold returns to the water tank 2 after diversion, and the other part continues to circulate, and the cold water in the water tank 2 is continuously replenished.

[0026] See also Figure 2 , 3 The refrigeration unit 3 includes a cold water pump 31 fixedly installed in the middle layer of the equipment cabinet 1 and a refrigeration module. A water pipe 35 is connected between the water inlet of the cold water pump 31 and the water outlet of the water tank 2, and the water outlet of the cold water pump 31 is connected to a water outlet pipe 36. The refrigeration module includes a plate evaporator 32, a compressor 33 and a plate condenser 34. The plate evaporator 32, the compressor 33 and the plate condenser 34 are connected by pipelines. The water inlet of the plate evaporator 32 is connected to a reflux pipe 37, and the water outlet of the plate evaporator 32 and the water inlet of the water tank 2 are connected to a water pipe 2 38.

[0027] See also Figure 4 , 5 The heating unit 4 includes a hot water pump 41 and a water distributor 42 fixedly installed on the bottom layer inside the equipment cabinet 1. The water inlet of the water distributor 42 is connected to a return pipe 43, and the water outlet of the water distributor 42 is directly connected to the water inlet of the hot water pump 41. An electric heat exchanger 44 is arranged on the upper part of the hot water pump 41. The water outlet of the hot water pump 41 is directly connected to the water inlet of the electric heat exchanger 44. The water outlet of the electric heat exchanger 44 is connected to an outlet pipe 45. A shunt pipe 46 is connected between the water distributor 42 and the outlet pipe 36. A shunt pipe 47 is connected between the outlet pipe 45 and the water supply pipe 38. A solenoid valve 48 is installed in series in the section of the shunt pipe 47, and a temperature sensor 49 is installed in the section of the return pipe 43.

[0028] It should be noted that an overheat protector is also installed inside the equipment cabinet 1. The temperature sensor 49 can communicate with the overheat protector, and the solenoid valve 48 is controlled by the overheat protector. That is, when the return water temperature detected by the temperature sensor 49 is greater than the set value, this signal will be transmitted to the overheat protector, and the overheat protector will control the solenoid valve 48 to open.

[0029] When in use, the control unit can provide cold water and hot water to the mold respectively. When cold water needs to be provided to the mold, the outlet pipe 36 is connected to the water inlet of the mold, and the return pipe 37 is connected to the water outlet of the mold. The cold water pump 31 is started to inject the chilled water in the water tank 2 into the mold. After cooling the mold, the hot water flows back to the plate evaporator 32. The hot water is cooled by the refrigeration module composed of the plate evaporator 32, the compressor 33 and the plate condenser 34. The cooled water returns to the water tank 2 and is then injected into the mold, and circulates in sequence.

[0030] When hot water needs to be provided to the mold, the cold water pump 31 pumps the water out of the water tank 2 and introduces the water into the water distributor 42 through the shunt pipe 46. The hot water pump 41 is then started to inject the water in the water distributor 42 into the electric heat exchanger 44. After being heated by the electric heat exchanger 44, the water is injected into the mold through the outlet pipe 45. After being used by the mold, the water flows back to the water distributor 42 through the return pipe 43. If the temperature sensor 49 detects that the return water temperature exceeds the set value, on the one hand, the cold water entering the shunt pipe 46 is mixed with the high-temperature water in the water distributor 42 to reduce part of the temperature. On the other hand, the solenoid valve 48 will open, and part of the water will return to the water tank 2 through the shunt pipe 47 and be combined with the cold water temperature in the water tank 2.
