Mold temperature control injection molding mold and system and process

Abstract

The invention relates to a mold temperature control injection molding mold and system and process. The mold temperature control injection molding system comprises an injection molding machine and themold temperature control injection molding mold, and the mold temperature control injection molding mold comprises an oil temperature device, a first cooling device and a second cooling device; and alower mold oil temperature device is arranged on a forming lower mold of the oil temperature device, and a first lower mold cooling device and a second lower mold cooling device are arranged on the forming lower mold and pass through a lower mold core. The process further comprises the steps of preparation, mold closing, injection molding, pressure maintaining, first cooling, second cooling, and mold opening. According to the process, the temperature control of the mold can be accurately achieved, the injection molding production cycle is effectively reduced, the product quality and the production efficiency are improved, a heating device is prevented from being additionally arranged, and the machining cost is reduced; meanwhile, the lower mold core can be cooled, and the cooling effect isimproved; and in addition, when cooling is required in the injection molding process, the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a mold temperature control injection molding mold, system and process thereof. Background technique [0002] Mold is an indispensable tool in injection molding. Injection molding is to inject hot-melt plastic material from the injection port of the mold into a closed cavity with the required shape in the mold. After the plastic material cools and solidifies, open the mold to A processing method in which cured plastic parts are ejected to obtain molded products. [0003] In the injection molding process, it is generally necessary to heat and cool the mold, and the existing mold needs to be equipped with a separate heating device and cooling device, resulting in high processing costs; in addition, the quality of injection molded products is largely affected by the temperature of the mold The existing mold cooling method is single, and generally it can only cool the formi...
