[0004] When cooling the injection mold in the above utility model, the cooling water is circulated. During the high-temperature circulation process, since ordinary cooling water dissolves a variety of salts, such as carbonates, silicates, etc., their metal salts have very low solubility.

In short, a large amount of scale will be generated during the long-term use of the circulating cooling device. Ordinary cooling equipment lacks a structure for quickly and effectively cleaning scale, which is not convenient for long-term stable operation of the equipment. If descaling liquid is directly added, high-temperature liquid gas is easy to erupt directly, which can easily cause harm to the staff. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-3 , the utility model provides two technical solutions:

[0022] Embodiment 1, an injection molding device with a circulating cooling structure, comprising a working base plate 1, a cooling component 2 for circulating cooling is fixedly connected to the top of the working base plate 1, a mold device 3 is fixedly connected to the inner wall of the cooling component 2, a descaling component 4 for circulating scale cleaning is connected to the top of the cooling component 2, the descaling component 4 comprises a feed pipe 41 connected to the top of the cooling component 2, a sealing inner ring 42 is fixedly connected to the top of the inner wall of the feed pipe 41, baffles 43 are fixedly connected to both sides of the inner wall of the feed pipe 41, a spring 44 is fixedly connected to one side of the top of the baffle 43, a support plate 45 is fixedly connected to the top of the spring 44, and the top of the support plate 45 is fixedly connected to the top of the spring 44. A support rod 46 is fixedly connected in the middle of the part, a sealing plug 47 is fixedly connected to the top of the support rod 46, one side of the support plate 45 is slidably connected to the inner wall of the feed pipe 41, and by utilizing the setting of the descaling component 4, when the device is in operation, the pipeline is aligned with the top of the feed pipe 41, and the sulfuric acid pushes the sealing plug 47 and the spring 44 at the bottom after being pressurized, and the sulfuric acid flows into the inside of the feed pipe 41. During the adding process, the high-temperature liquid and gas inside the circulating cooling equipment are all restricted to the bottom of the feed pipe 41 and will not spray out directly. After the adding is completed, the spring 44 pushes the sealing plug 47 to seal the sealing inner ring 42, thereby ensuring that the staff can operate the equipment safely.

[0023] Embodiment 2 is mainly different from Embodiment 1 in that: an injection molding device with a circulating cooling structure, the cooling assembly 2 includes a water pump 21 fixedly connected to the top of the working base plate 1, a cooling head 22 fixedly connected to the top of the water pump 21, a cooling frame 23 fixedly connected to the top of the cooling head 22, the cooling frame 23 is made of copper, a conductive plate 24 is fixedly connected to the inner wall of the cooling frame 23, one side of the conductive plate 24 is tightly fitted with the surface of the mold device 3, the conductive plate 24 is made of silver and the number is set to four, a water tank 25 is fixedly connected to the top of the cooling frame 23, a water inlet pipe is arranged on the top of the water tank 25, a water outlet pipe is arranged on the bottom of the front side, and the inner walls of the water inlet pipe and the water outlet pipe are provided with An electric control valve is arranged, reinforcing ribs are arranged on the surface of the water tank 25, a heat dissipation fin 26 is fixedly connected to the right side of the top of the working base plate 1, and a plurality of metal sheets are arranged on the surface of the heat dissipation fin 26 to improve the heat dissipation efficiency, a fan group 27 is fixedly connected to one side of the top of the working base plate 1, the heat dissipation fin 26, the water tank 25 and the water pump 21 are connected through a hose, and by utilizing the setting of the cooling component 2, the fan group 27 can directly blow air to cool down the high-temperature liquid passing through the heat dissipation fin 26, and the temperature in the mold device 3 can be quickly conducted to the outside and the circulating liquid through the cooling head 22, the cooling frame 23 and the conduction plate 24, and the conduction plate 24 fits tightly with the mold device 3, and the heat conduction efficiency is relatively high.

[0024] When filling, sulfuric acid is filled into the descaling component 4 as a cleaning liquid. Adding hydrochloric acid will bring in chloride ions, which will increase the corrosiveness. Adding nitric acid will bring in nitrate ions, which will provide nutrients for nitrifying bacteria and promote the reproduction of nitrifying bacteria. Therefore, only sulfuric acid can be used. After adding sulfuric acid, the pH value drops to 6.0-7.0, and the scaling water quality becomes corrosive water quality. It is necessary to add corrosion inhibitors or discharge the mixed liquid regularly.

[0025] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] During operation, water is added to the water tank 25, the water pump 21 and the fan group 27 are turned on, and the equipment operates normally. The heat in the mold device 3 is conducted to the cooling head 22 through the conduction plate 24 and the cooling frame 23, and finally enters the circulating water. The high-temperature water is directly conducted to the heat dissipation fins 26 through the water pump 21. The fan group 27 runs at high speed to dissipate the heat outward. The high-temperature water reduces the temperature after passing through the heat dissipation fins 26 and continues to circulate. After the device has run for a period of time, when the amount of internal scale is large, the external pipeline is aligned with the feed pipe 41, and the supply switch is turned on. The sulfuric acid with a large pressure directly presses down the sealing plug 47, and squeezes the spring 44 through the support rod 46 and the support plate 45. The sulfuric acid enters the water tank 25 through the feed pipe 41 and finally enters the circulation. After the addition of sulfuric acid stops, the spring 44 pushes the sealing plug 47 to seal the sealing inner ring 42, and the circulation and cooling work continues. When the device is finished, the device is restored.
