[0002] In the plastic mold injection industry, for more than thirty years since the 1990s, there has been a problem that due to the complex shape of the product, the mold cannot be processed by traditional waterways to cool the mold, resulting in problems such as appearance defects, warping deformation, and too long production cycle of the product. In 2015, a technology called "3D metal printing special-shaped waterways for molds" was created and invented by EOS Company in Germany. This technology combines special metal powders and special laser sintering technology. Using the principle of 3D scanning and layer-by-layer stacking, it changes the traditional way of using machines and tools for mold processing, and instead uses the new technology of laser scanning sintering and stacking to print the mold.

[0025] Using pure water to cool the plastic mold through the cooling water path can effectively avoid the possibility of water path blockage, ensure the normal operation of the cooling system. The returned pure water enters the pure water tank body 2, and the temperature is diluted and reduced. And the pure water tank body 2 is cooled again by the cooling assembly.

[0027] Through the cooperation of the return water connecting pipe 41 and the return water joint 42, the purified water flowing through the water path in the plastic mold can be effectively introduced into the purified water tank body 2 for cooling.

[0028] The control host 1 is also provided with a data display screen 11, and the data display screen 11 is electrically connected to the controller assembly.

[0029] The water outlet assembly includes a cooling member 5, a water outlet connecting pipe 6 and a water outlet joint 7. The cooling member 5 is arranged between the water outlet connecting pipe 6 and the water outlet joint 7, and a cooling channel is arranged in the cooling member 5. Both ends of the cooling channel are respectively connected to the water outlet connecting pipe 6 and the water outlet joint 7.

[0030] Through the setting of the cooling member 5, the water cooled in the purified water tank body 2 can be further cooled. While solving the problem of limited cooling capacity of the purified water tank body 2, it can also solve the problem that the water pump 3 generates heat during long-term operation, causing the water pump 3 to transfer its own heat to the pumped purified water. The cooling member 5 can further cool the purified water, realizing three-stage cooling treatment, and further improving the temperature control ability of the purified water mold water cooling temperature control machine.

[0031] The cooling assembly includes a water tower inlet joint 81, a water tower inlet conduit 82, a cooling conduit 83, a water tower outlet conduit 84 and a water tower outlet joint 85 connected in sequence.

[0034] Through the settings of the inlet three-way joint 86 and the outlet three-way joint 87, it is possible to make the two cooling processes share one water tower inlet joint 81, so that the two cooling processes can be achieved without the need to additionally set up an independent cooling structure, simplifying the structure of the product and having a relatively high degree of integration.

[0035] During the cooling process of the plate heat exchanger, the metal heat conduction plate between the cooling chamber and the water flow chamber will transfer the temperature of the coolant in the cooling chamber to the pure water in the water flow chamber to achieve cooling.

[0036] The shape of the cooling conduit 83 is spiral, and the cooling conduit 83 is arranged around the water pumping port.

[0037] By arranging the cooling conduit 83 around the water pumping port, it is possible to accurately cool the pure water within the water pumping range of the water pump 3 and ensure the stability of the water temperature of the pure water within the water pumping range of the water pump 3.

[0038] A pump head 32 is provided on the water pump 3. The pump head 32 is arranged in the pure water tank body 2, and the water pumping port is arranged at the end of the pump head 32.

[0039] The cooling conduit 83 is arranged around the pump head 32, which can play a certain role in cooling the pump head 32.

[0043] Moreover, with the setting of the pressure sensor 91, it can cooperate with the water pump 3 to automatically adjust the water supply pressure according to the different bends and the diameter of the water channels of the plastic mold, so as to supply the different pressures required for water channels of different diameters on the one hand, and achieve the effect of energy saving due to the automatic adjustment of pressure on the other hand.

[0044] A water flow velocity detection component is provided on the water pump 3. The water flow velocity detection component is electrically connected to the controller assembly, and the water flow velocity detection component can detect the flow velocity and flow rate of the pure water conveyed by the water pump 3.

[0045] By facilitating the processing personnel to master the operation parameters of the cooling system and make adaptive adjustments.

[0046] The water flow velocity detection component is a current transformer.

[0047] A water volume detection component is provided in the pure water tank body 2. The water volume detection component is electrically connected to the controller assembly. Through the setting of the water volume detection component, the water volume information in the pure water tank body 2 can be detected.

[0048] The water volume detection component includes a floating ball 12 and a proximity switch 13. The floating ball 12 is arranged in the pure water tank body 2, and an induction component 121 is arranged at the upper end of the floating ball 12. A highest water level contact plate 131 and a lowest water level contact plate 132 are arranged on the proximity switch 13. When the pure water in the pure water tank body 2 decreases or increases, the floating ball 12 will descend or rise, so that the induction component 121 contacts the highest water level contact plate 131 or the lowest water level contact plate 132 to identify the current water level information and give an early warning in advance.

[0049] A water level warning buzzer 14 is arranged on the control host 1. The water level warning buzzer 14 is electrically connected to the controller assembly and can cooperate with the water volume detection component to give a water level warning.

[0050] A highest water level overflow pipe 15 is arranged on the pure water tank body 2, so that when too much water is added through the pure water injection port 21, the water above the specified water level will flow out from the highest water level overflow pipe 15.

[0051] The pure water mold water cooling temperature control machine further includes a water tank heating component. The water tank heating component is electrically connected to the controller assembly, and a temperature sensor 17 is arranged in the water outlet component.

[0052] Through the setting of the water tank heating component, the pure water in the pure water tank body 2 can be heated, and cooperate with the temperature sensor 17 to detect the stability of the pure water conveyed to the plastic mold in real time, ensure that the pure water conveyance is stable within the specified range, and avoid too high or too low temperature.

[0053] The water tank heating assembly includes multiple groups of heating tubes 16, which are arranged in the pure water tank body 2, and the multiple groups of heating tubes 16 are arranged on different sides inside the pure water tank body 2.

[0054] With this arrangement, the water tank heating assembly can heat the pure water more evenly.

[0055] A water discharge pipe 22 is also arranged on the pure water tank body 2. The arrangement of the water discharge pipe 22 can facilitate the cleaning of the inside of the pure water tank body 2.

[0056] The working process of a pure water mold water-cooling temperature control machine provided in this embodiment is as follows: The embodiment of the present invention provides advantages of small waterway blockage and high cooling efficiency compared with the existing water-cooling system.

[0057] First, pure water is injected into the pure water tank body 2 from the pure water injection port 21.

[0058] After being filled, the water pump 3 pumps the pure water into the waterway of the plastic mold. The pure water flows through the water cooling and then flows back to the pure water tank body 2 through the return water connection pipe 41. The temperature of the pure water flowing back through the waterway is diluted by the pure water in the pure water tank body 2 for the first cooling and temperature reduction. Then, the cooling assembly cools the pure water in the pure water tank body 2 again for the second cooling and temperature reduction. The water pump 3 then injects the pure water in the pure water tank body 2 into the cooling part 5, and the cooling part 5 cools the pure water for the third cooling and temperature reduction. The cooled pure water finally flows into the plastic mold, and this cycle cools the plastic mold and cools the pure water flowing through the waterway.

[0059] As can be seen from the above, the present invention provides a pure water mold water-cooling temperature control machine. By using pure water in the cooling waterway to cool the plastic mold, it can effectively avoid the possibility of waterway blockage, ensure the normal operation of the cooling system. The temperature of the pure water flowing back into the pure water tank body 2 is diluted and cooled, and the cooling assembly cools the pure water tank body 2 again. By cooling multiple times, the temperature control ability of the water-cooling system is improved, achieving the cooling effect of replacing the compressor, effectively improving the production efficiency of the manufacturer, and solving the problem in the prior art that using external water for cooling causes the small waterways to be blocked by impurities in the external water, affecting the production efficiency.

[0060] The above-mentioned specific implementation manner is the preferred implementation manner of the present invention, and does not limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation manner. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
