[0017] A method for using a medical device part molding mold with rapid cooling, comprising the following steps:

[0018] S1: When the mold is cooled, the motor and the water pump are started. The start of the motor drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the fan to rotate, so that air enters the air inlet pipe from the air inlet hole. The air enters the air inlet pipe and is filtered by the filter plate and then flows to one side of the cooling device.

[0019] S2: When the water pump is started, water is drawn from the liquid storage chamber through the first water pipe and transmitted through the second water pipe, and finally sprayed out from the nozzle, the water contacts the gas, and the impurities in the gas are adsorbed and filtered again by the water;

[0020] S3: When water enters the first water pipe and flows upward, it drives the rotating plate to rotate, the rotation of the rotating plate drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the first gear, the rotation of the first gear drives the rotation of the second gear, the rotation of the second gear drives the rotation of the fixed block, the rotation of the fixed block drives the filter plate to rotate, so that the filter plate rotates when it contacts the gas, so that the air forms a dynamic flow when passing through the filter plate;

[0021] S4: The filtered gas continues to flow to one side of the cooling device and then enters the cooling device after being cooled by the cooling fins;

[0022] S5: After the gas enters the cooling device, the water in the gas is absorbed by the water absorption plate and finally discharged from the air outlet to cool the mold.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention starts the motor when the mold is cooled by setting the filter plate. The start of the motor drives the rotation of the first rotating shaft. The rotation of the first rotating shaft drives the rotation of the fan, so that air enters the air inlet pipe from the air inlet hole, enters the cooling device after being filtered by the filter plate, and is finally discharged from the air outlet to cool the mold. This avoids the problem that the airflow generated during the blowing process will drive the tiny particles in the surrounding environment to flow together, and dust is easily blown onto the surface of the mold by the airflow, affecting the appearance quality of the product. Air filtration can ensure the quality of the finished product of the mold.

[0025] 2. The present invention sets a spray assembly. When the mold is cooled, the water pump is started, and the water source inside the liquid storage chamber is extracted through the first water pipe and transmitted through the second water pipe. Finally, the water is sprayed out from the nozzle, and the water contacts the gas. The impurities in the gas are adsorbed and filtered by the water, thereby further improving the filtering effect of the gas and reducing the possibility of impurities in the gas adhering to the mold surface, thereby improving the quality of the finished mold.

[0026] 3. The present invention arranges a rotating assembly. When water enters the first water pipe and flows upward, it drives the rotating plate to rotate. The rotation of the rotating plate drives the second rotating shaft. The rotation of the second rotating shaft drives the first gear. The rotation of the first gear drives the second gear. The rotation of the second gear drives the fixed block. The rotation of the fixed block drives the filter plate to rotate. The filter plate rotates when it contacts the gas, so that the air forms a dynamic flow when passing through the filter plate. This helps to better capture and adsorb particles in the air, and can ensure the uniform distribution of air on the filter plate, avoiding excessive blockage in local areas, thereby improving the efficiency of the entire filtration system and improving the stability of gas filtration.
