Intelligent mold temperature control system for high-fineness weldless injection molding

Abstract

The invention relates to an intelligent mold temperature control system for high-fineness weldless injection molding. The system comprises a PLC processing terminal for processing data, a temperaturedetection module for detecting the temperature of a mold, a threshold module, a temperature judgment module, a high-temperature steam rapid heating module, a high-temperature steam insulation module,a drive adjustment module, a time calculation module and a rapid cooling module, wherein the threshold module is used for providing a low temperature threshold corresponding to rapid heating of the mold and a high temperature threshold corresponding to high temperature maintaining of the mold; a rapid heating temperature database and high-temperature maintaining temperature values are arranged inside the temperature judgment module; the high-temperature steam rapid heating module stores a steam incremental injection database; the high-temperature steam insulation module stores a steam constantinjection database; the drive adjustment module calls the corresponding steam injection amount to inject the mold for rapid heating or high-temperature maintaining; the mold high-temperature maintaining time values are preset in the time calculation module, and timing is started when the mold temperature reaches the high temperature threshold; the rapid cooling module is used for rapidly coolingthe mold when the calculated time reaches the time value after high temperature maintaining. The system can accurately control the temperature of the mold and improve quality of products.

Description

technical field [0001] The invention relates to the technical field of mold injection molding, in particular to an intelligent mold temperature control system for high-gloss seamless injection molding. Background technique [0002] High-gloss seamless injection molding generally uses steam heating. When the injection molding machine closes the mold and injects heat energy, first raise the mold temperature to a set value, and then start to inject plastic into the cavity. Cold water, after the mold temperature drops to a set value, the cold water is discharged, the mold is opened and the parts are taken, and the entire injection molding process is completed. [0003] The existing high-gloss traceless injection molding system, such as a Chinese utility model patent with the notification number CN204340144U, discloses a high-gloss traceless injection molding system, including a quality inspection mechanism, a high-gloss steam mechanism and a transmission mechanism, and the quali...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the above-mentioned high-gloss seamless injection molding system heats the mold through steam during the mold injection process, but does not control the temperature of the mold during the heating or even the heat preservation and pressure holding process. detection, and did not control the input amount of steam according to the temperature required by the mold, so that the temperature of the mold could not be accurately controlled, resulting in the fact that during the injection molding process, the material cannot be melted normally when the temperature is low, and the material is easy to melt when the temperature is high. Melting and vaporization, reducing the quality of the product
