Description

[Technical Field]

[0001] This invention relates to the field of mold temperature transformation technology, specifically to a multi-medium rapid heating and cooling system. [Background Technology]

[0002] In current rapid heating and cooling systems for molds, the heat source medium typically uses steam or high-pressure hot water to raise the mold temperature. Current technologies generally use a pressure of 7 kg / cm² and a heat source medium temperature of 164°C. When the mold temperature needs to be above 164°C, current technical solutions include:

[0003] Option 1: Increase the saturated steam pressure of steam or hot water to 40 kg / cm2 at 249 degrees Celsius. This will put the mold and connecting pipes under great pressure, which will easily lead to mold cracking and pipe bursting due to frequent hot and cold alternation during the heating and cooling process. Moreover, the mold temperature can only be raised to a maximum of 230 degrees Celsius, which cannot meet the requirements of higher temperatures.

[0004] Option 2: Use hot kerosene as the medium for heating and cooling. However, the thermal conductivity of high-temperature oil is about 0.11-0.13 W / mK, compared to 0.67 W / mK for water, which is about 6 times higher. Therefore, the heating and cooling time of high-temperature oil is long, resulting in low production efficiency and high costs.

[0005] In view of this, it is necessary to provide a multi-medium rapid heating and cooling system to solve the safety hazards, inefficiency, and high cost of the current mold heating and cooling methods. [Summary of the Invention]
