[0002] Injection molding processing is a commonly used method for plastic processing. By heating and melting plastic particles, injecting them into a mold, and then cooling them to form a shape. During the injection molding process, a cooling device is usually used to cool the mold to accelerate the cooling speed of the material inside the mold, thereby improving the efficiency of injection molding processing.

A lower shell is installed at the top of the base, a lower mold is embedded inside the lower shell, an upper shell is installed on an external lifting mechanism, a heat-conducting liquid is injected inside the upper shell, and an upper mold is embedded inside the upper shell. When cooling, the heat-conducting liquid inside the lower shell and the upper shell absorbs the heat in the mold, and then the heated heat-conducting liquid is transported to the cooling device for cooling, and then transported back to the inside of the lower shell and the upper shell again to make it circulate, so as to cool and lower the temperature of the mold.

[0004] There are still problems in the above-mentioned injection mold cooling device. The cooling device is large in volume and cannot adjust the cooling speed during use, resulting in too fast cooling speed of the material inside the mold. Due to thermal expansion and contraction, the workpiece deforms, and the quality of injection molding processing decreases. Therefore, an injection molding cooling device is proposed. Summary of the Utility Model

Fixing plates 16 are fixed at both ends of the heat conduction copper tube 2. During operation, when encountering the problem that the existing cooling device is large in volume and unable to adjust the cooling speed, resulting in a decline in the quality of injection molding processing, through the structure of the cooling mechanism, according to the need, an appropriate number of water valves 7 are opened, water source is injected through the water inlet 10, and it flows into the cavity 5 inside the heat conduction copper tube 2 through the opened water valves 7. At the same time, it flows into the inside of the heat dissipation plate 3 through the input pipe 14. The heat inside the mold body 201 is absorbed by the heat conduction pad 6.

Both ends of the threaded rod 19 penetrate inside the fixing plate 16, and the threaded rod 19 is rotatably connected to the fixing plate 16. A sliding groove 101 is opened on the side of the support frame 1; during work, when encountering the problem that the existing cooling device has a complex structure and is inconvenient for subsequent maintenance, through the structure of the fixing mechanism, the mold body 201 is buckled on the heat-conducting copper tube 2, so that it is closely attached to the heat-conducting pad 6.

[0026] Working principle: Injection molding is a commonly used method for plastic processing. By heating and melting plastic particles, injecting them into a mold, and allowing them to cool and form. During the injection molding process, a cooling device is usually used to cool the mold to accelerate the cooling speed of the material inside the mold, thereby improving the efficiency of injection molding. Existing cooling devices are large in size and cannot adjust the cooling speed during use, resulting in too fast cooling speed of the material inside the mold. Due to thermal expansion and contraction, the workpiece deforms and the quality of injection molding decreases. To solve this problem, by setting a cooling mechanism and a fixing mechanism, the mold body 201 is buckled on the inner side of the heat-conducting copper tube 2, making it closely fit with the heat-conducting pad 6. At this time, the mounting seat 17 is buckled on the inner side of the fixing plates 16 at both ends of the heat-conducting copper tube 2, and the threaded rods 19 inside the mounting seat 17 are respectively inserted and installed in the fixing plates 16. At this time, rotate the threaded rod 19 to push the fixing plates 16 on both sides to move towards the mounting seat 17, so that, with the cooperation of the heat-conducting copper tube 2, the mold body 201 is clamped and fixed. According to requirements, open an appropriate number of water valves 7, inject water through the water inlet 10, and make it flow into the cavity 5 inside the heat-conducting copper tube 2 through the opened water valves 7. At the same time, it flows into the heat dissipation plate 3 through the input pipe 14. The heat-conducting pad 6 absorbs the heat inside the mold body 201. At this time, the heated liquid is transported to the inside of the water outlet pipe 12 through the conduit 11 and the output pipe 15 and discharged through the water outlet 13. The mold is cooled by the way of circulating water flow inside it, and the cooling speed can be adjusted according to requirements. After the mold is cooled, pull the rectangular plate 23 to drive the insertion rod 24 to be pulled out from the through hole 21 and the positioning hole 22, thereby releasing the fixation of the slider 20. At this time, the heat-conducting copper tubes 2 on both sides can be pulled, and they slide and separate towards both ends inside the chute 101 with the cooperation of the slider 20, so as to follow the opening of the molds on both sides. Then, insert the insertion rod 24 into the through hole 21 and the positioning hole 22 again to fix the position of the mold, and the cooled workpiece inside the mold can be taken out, solving the problems of large size and inability to adjust the cooling speed of the existing cooling device.
