[0003] In-mold cooling is the most commonly used cooling method, which cools and shapes the parison through the cooling system built in the mold, and the cooling medium is usually water, chilled water or chilled gas, which circulates through the cooling hole in the mold, effectively taking away heat and promoting the solidification of plastic. In order to shorten the forming cycle and improve production efficiency, the cooling time is limited, so that the packaging material is directly discharged after preliminary cooling and falls into the frame for further cooling. Since part of the packaging material has not been completely cooled, direct discharge may cause deformation due to collision, resulting in decreased dimensional accuracy and increased appearance defects, thereby increasing the rate of defective products and affecting product quality and production cost.
