However, the conventional insert cooling method has the following drawbacks:

(1) The insert has long processing period and high processing cost, and needs five-axis processing equipment and numerical control deep-hole drilling equipment, which is not matched with the requirements of short rapid trial-manufacture period and low cost;

(2) The quantity of cooling liquid channels in the insert is limited, so that the die is not cooled effectively, the thermoforming time is long, and the processing efficiency is low.
