[0017] The plastic bottle mold with a rapid cooling function completes the blow molding of the plastic bottle through the mold body.

The cold water flows in the coil and absorbs the heat brought out by the heat dissipation fins for heat exchange, thereby realizing rapid cooling of the mold body and improving the production efficiency of the plastic bottle. After absorbing the heat, the cold water flows back to the water tank again and is continuously cooled by the refrigeration sheet, ensuring that the water source in the water tank is always kept in a low-temperature device, thereby improving the cooling effect of the mold body.

[0025] In actual use of the above structure, the hot melt plastic tube is placed between the mold bodies 6, and the first motor 12 is turned on at this time. The first motor 12 drives the bidirectional screw 11 to rotate, and the bidirectional screw 11 drives the movable plate 4 through the moving block 10, so that the mold body 6 is combined to ensure that the hot melt plastic tube is located inside the mold body 6. At this time, high-pressure gas is blown into the mold body 6 through the blow molding port 7, and the hot melt plastic tube is squeezed and blown into the shape of the inside of the mold body 6 to be formed into a plastic bottle.
