AI Technical Summary

Technical Problem

In rapid cooling molds for polymer materials, the water flow in the cooling water channel is in a laminar flow state, resulting in a low heat transfer coefficient and a large temperature difference between the center of the pipe and the pipe wall, which affects the rapid cooling efficiency of the mold.

Method used

A reverse heat exchange enhancement mechanism is installed in the inlet and outlet water pipes, including a mounting ring, interference ring, connecting frame, bearing and spiral blade, forming a conical structure to break the laminar flow state and form turbulent flow, thereby improving heat exchange efficiency. It also forms a closed-loop system through the connecting pipe to promote uniform water flow distribution.

Benefits of technology

It significantly improves the cooling efficiency and uniformity of the mold, reduces temperature difference, lowers energy consumption, and improves production efficiency and mold usability.

Abstract

The utility model discloses a rapid cooling mold for high polymer material forming, and relates to the field of high polymer material forming molds. The mold comprises a mold body, the mold body comprises a lower mold body, an upper mold body, a water inlet pipeline and a water outlet pipeline, and heat exchange enhancing mechanisms are arranged in the water inlet pipeline and the water outlet pipeline respectively. A spiral blade is arranged on a rotating rod in the heat exchange enhancing mechanism, when the water flow passes through, the spiral blade disturbs the water flow, breaks the laminar flow state and forms turbulent flow, and in the turbulent flow state, heat exchange between fluid and the solid wall face is more sufficient, the heat exchange coefficient is remarkably increased, and the cooling effect is enhanced. By means of the arrangement, the problems that the heat exchange coefficient is low due to the laminar flow state of water flow in the cooling water channel, the temperature difference between the pipe center and the pipe wall is large, effective heat transfer is not facilitated, and the rapid cooling efficiency of the mold is affected are effectively solved.
