The invention discloses a technology for holding pressure control according to melting body temperature as an injection molding machine, comprising the following technical steps: A), installing a melting body temperature sensor on the mould cavity or pouring gate of an injection machine for measuring the melting body temperature; B), connecting the output signal of the melting body temperature sensor to an injection machine controller; C), writing the holding pressure control procedure in the injection machine controller as the holding pressure switch according to the melting body temperature; D), in the injection holding pressure process, the melting body temperature in the mould cavity is quickly increased firstly and slowly reduced then, after the temperature reaches the top point, the invention performs transfer holding pressure, holding pressure switch and holding pressure end control according to the set melting body temperature. The invention has the advantages of high injection product quality and repeat accuracy.
Description
【Technical field】 [0001] The present invention relates to a control process for pressure-holding control of plastic products produced by injection molding machines, more specifically, it relates to a control method for pressure-holding control process, which can improve the quality and repeatability of injection products of injection molding machines . 【Background technique】 [0002] As a main processing molding process, injection molding has the advantages of easy large-scale production, light weight, stable structure and low price. With the rapid development of my country's plastics industry, higher requirements are put forward for the quality and repeatability of injection products. The conventional way of improving product quality and repeatability is to use precision injection molding machines and precision molds for production, but this will lead to a substantial increase in equipment investment and production costs. An effective way to improve the quality and repeat...
