Problems solved by technology

However, after the mold is cooled by this method, usually part of the heating / cooling medium will remain in the heating / cooling circuit, and steam will be generated during heating in the next molding cycle, thereby affecting the heating effect of the mold, which is not conducive to rapid heating, resulting in molding cycle extension

Abstract

An ejection moulding system is composed of a mould with internal heater, cooling channel and temp sensor, a valve connected to one end of said cooling channel, a controller connected to said heater and valve, and a negative pressure unit connected to another end of said cooling channel and said controller. Its ejection moulding method is also disclosed.

Description

【Technical field】 [0001] The invention relates to an injection molding system, in particular to an injection molding system and method capable of rapid heating and cooling. 【Background technique】 [0002] In the injection molding process, especially the injection molding process of thermoplastics, it is usually necessary to heat the mold to a higher temperature when the thermoplastic is injected to improve the fluidity of the thermoplastic, so as to obtain a shaped product with high surface accuracy after cooling. However, the molding cycle of the injection molded product also prolongs as the mold temperature change time increases, resulting in reduced production efficiency. [0003] In order to shorten the molding cycle of injection molding products and improve production efficiency, a mold heating method is provided in the prior art. This method only heats the part near the molding surface of the mold when the thermoplastic is injected, and because the temperature change ...
