Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic molds, specifically a cooling mechanism for plastic molds. Background Technology
[0002] Plastic mold is a type of combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes of the mold's punch, die, and auxiliary molding system can produce a series of plastic parts of different shapes and sizes.
[0003] A search revealed a patent with patent application number 202322485771.1, which discloses a plastic mold cooling mechanism. The mechanism includes a mold base with support columns fixed on both sides above it. A lower mold is positioned above the mold base, and a heat-conducting plate is installed above it. Heat dissipation fins are positioned below the heat-conducting plate, and a cooling pipe is installed on one side of each fin. One end of the cooling pipe has a water inlet pipe, and the other end has a water outlet pipe. A first flange is installed on one side of the water inlet pipe. This plastic mold cooling mechanism, through the coordinated use of the heat-conducting plate, heat dissipation fins, cooling pipe, water outlet pipe, water inlet pipe, water tank, and water pump, allows the heat generated by the lower mold to be conducted through the heat-conducting plate. The heat is then transferred to the heat dissipation fins, where heat exchange occurs between the fins and the cooling pipes, cooling the lower mold effectively. The water tank and water pump facilitate the circulation of water in the cooling pipes, reducing the operating cost of the device. The above-mentioned patent also has the following shortcomings: the cooling mechanism described above performs heat exchange and cooling operation by directly contacting the bottom of the lower mold with the heat-conducting plate installed above the mold base. However, due to the limited contact area between the heat-conducting plate and the lower mold, the cooling effect of the mold is not good. Therefore, a plastic mold cooling mechanism is proposed to optimize and solve the above problems. Utility Model Content
