Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and more specifically, to a mold cooling mechanism for hot runner molds. Background Technology

[0002] Injection molding technology refers to the molds and related technologies used in the design, manufacture, and application of plastics during the molding process. Its core is the process of injecting molten plastic material into a pre-designed mold, followed by cooling and solidification to form the final product. With the rapid development of the plastics industry, the requirements for injection molding technology are becoming increasingly stringent.

The detachable connection between the temperature control ring and the temperature control tube facilitates the maintenance and cleaning of the cooling mechanism, reduces maintenance costs, and allows for the recovery of the temperature control medium through the temperature control valve. This ensures operational quality and efficiency while maximizing resource conservation and improving resource utilization. Utility Model Content

The temperature control valve 110 opens the pipe connected to the temperature control valve 110. The temperature control module calculates the energy consumed to cool the current temperature to the maximum temperature of the lower limit temperature and the energy consumed to heat the current temperature to the minimum temperature of the upper limit temperature. The temperature control module rotates the valve according to the amount of energy consumed.

[0078] Understandably, the recycling of the temperature-controlled medium effectively avoids resource waste. By calculating the energy consumption through the temperature control module and selecting connecting pipelines, resource savings are maximized and resource utilization is improved while ensuring operational quality and efficiency.
