Description

Technical Field

[0001] The utility model relates to the technical field of injection molding part cooling, in particular to a cooling device for high-impact injection molding pipe fittings. Background Art

[0002] The cooling device for injection molding pipe fittings is an indispensable part of the injection molding process. Its main purpose is to rapidly reduce the temperature of plastic pipe fittings after they are formed from the mold, so as to promote material curing and control the dimensional stability, surface quality and production cycle of the product.

[0003] For common cooling devices for injection molding pipe fittings, the cooling effect is poor, and the cooling efficiency of injection molding parts is low, resulting in the occupation of a large amount of factory space, affecting the operation of workers. Moreover, in the common water cooling method, the initial cooling effect is significant, and water can quickly absorb heat and cool down in the first half of the pipeline. However, as the water temperature rises, its heat absorption capacity weakens, resulting in a decline in the cooling efficiency of water in the second half of the pipeline, promoting poor cooling uniformity and affecting the stability and consistency of the cooling effect.

[0004] Therefore, aiming at the lack of air cooling components and water cooling components in the above-mentioned cooling device for injection molding pipe fittings, the cooling effect is poor, the cooling efficiency of injection molding parts is low, resulting in the occupation of a large amount of factory space, affecting the operation of workers, and in the common water cooling method, and the initial cooling effect is significant, water can quickly absorb heat and cool down in the first half of the pipeline. However, as the water temperature rises, its heat absorption capacity weakens, resulting in a decline in the cooling efficiency of water in the second half of the pipeline, promoting poor cooling uniformity and affecting the stability and consistency of the cooling effect, which urgently needs to be solved to improve the use scenario of the cooling device for injection molding pipe fittings. Summary of the Utility Model

[0005] In order to overcome the common cooling device for injection molding pipe fittings, which has a low cooling efficiency, and in the water cooling method during use, the first half cools faster but the cooling effect weakens in the second half due to the rise in water temperature, and it is impossible to ensure the uniform and stable cooling process.

The air cooling component includes a lower shell, an upper shell and a heat dissipation fan, and the water cooling component includes a fixing plate, a water pump, a serpentine cooling pipe, a heat conduction rod, a square cooling pipe and a mounting groove.

[0007] Preferably, through the cooperation of the air-cooling component and the water-cooling component, the cooling effect is improved to solve the problems of common cooling devices for injection-molded pipe fittings, such as poor cooling effect, low cooling efficiency of injection-molded parts, which leads to the occupation of a large amount of factory space and affects the work of workers. The air-cooling component evenly cools the water in the cooling pipe to solve the problem that the water can quickly absorb heat and cool down in the first half of the pipe. However, as the water temperature rises, its heat absorption capacity weakens, resulting in a decrease in the cooling efficiency of the water in the second half of the pipe, promoting poor cooling uniformity and affecting the stability and consistency of the cooling effect.

[0008] Preferably, a plurality of fixing plates are fixedly arranged on the inner side wall of the circulation water tank. A water pump is fixedly arranged on the upper end surface of the fixing plate. One end of a serpentine cooling pipe is fixedly connected to the output ends of the water pumps on both sides, and one end of a square cooling pipe is fixedly connected to the output end of the inner water pump. Start a plurality of water pumps to transport the water in the circulation water tank into the serpentine cooling pipe and the square cooling pipe.

[0009] Preferably, the other ends of the serpentine cooling pipe and the square cooling pipe extend into the circulation water tank. A plurality of installation grooves are formed in the inner walls of the lower mold and the upper mold. The serpentine cooling pipe and the square cooling pipe are installed inside the installation grooves, so that the serpentine cooling pipe and the square cooling pipe are in close contact with the injection-molded part, improving the heat conduction effect and quickly taking away the heat by water.

[0010] Preferably, an injection hole is formed in the upper end surface of the upper mold. The injection hole penetrates through the upper end surface of the upper mold and extends into the cavity formed between the lower mold and the upper mold. Through the injection hole, the plastic melt enters the upper mold and the lower mold to form the expected product shape.

One end of a plurality of heat conduction rods is arranged inside the serpentine cooling pipe, and the other ends of a plurality of heat conduction rods respectively penetrate through the lower mold and the upper mold and extend into the lower shell and the upper shell. By arranging the heat conduction rods, the temperature of the water in the serpentine cooling pipe can be transferred, the temperature of the water in the serpentine cooling pipe can be reduced, and the heat absorption and cooling effect of the water in the second half of the serpentine cooling pipe is improved.

[0013] Preferably, two cooling fans are installed in the mounting holes on the upper end surface of the upper shell, and a mold splitting module is installed at the connection between the left and right sides of the lower shell and the upper shell. Starting the cooling fans can drive the flow of external cold air. The external cold air enters the lower shell and the upper shell and is discharged through the holes on the lower end surface of the lower shell. During this period, the cold air contacts the surface of the heat conduction rods, taking away the temperature on the surface of the heat conduction rods.

[0026] See also Figures 1-5, in this embodiment, an injection hole 9 is provided on the upper end surface of the upper mold 6. The injection hole 9 penetrates through the upper end surface of the upper mold 6 and extends into the cavity formed between the lower mold 6 and the upper mold 5.

The serpentine cooling pipe 83 cools the front and rear sides of the lower mold 5 and the upper mold 6. Starting the heat dissipation fan 43 can drive the flow of external cold air. The external cold air enters the lower shell 41 and the upper shell 42, and is discharged through the hole on the lower end surface of the lower shell 41. During this period, the cold air contacts the surface of the heat-conducting rod 84 and takes away the temperature of the surface of the heat-conducting rod 84. The heat-conducting rod 84 can conduct heat to the water inside the square cooling pipe 85 and the serpentine cooling pipe 83, so that the coolant inside the cooling pipe can take away more heat to improve the heat dissipation efficiency.

However, as the water temperature rises, its heat absorption capacity weakens, resulting in a decrease in the cooling efficiency of the water in the second half of the pipe, resulting in poor cooling uniformity, affecting the stability and consistency of the cooling effect.
