Externally connected control system of in-mould laminating special injection molding machine and method thereof

Abstract

The invention relates to an externally connected control system of an in-mould laminating special injection molding machine and a method thereof. The control system comprises a display unit, a controlunit and an interface unit, wherein the display unit comprises an LCD displayer and a liquid crystal touch screen; the control unit comprises an upper computer control unit and a lower computer control unit; the control core of the upper computer control unit is an industrial personal computer with a PC104 bus interface; the industrial personal computer drives the LCD displayer, receives commandsof the liquid crystal touch screen, transmits the commands to a lower computer and receives commands of an upper computer so as to control actions. The system and the method can realize the linkage of the externally connected control system and a common injection molding machine control system, realize control functions of heating a hot runner, controlling temperature, opening and closing the die, drawing a core and opening and closing a valve gate, and achieve the aims of openness, low cost and saving space.

Description

technical field [0001] The invention relates to a special injection molding machine for in-mold lamination, and more specifically relates to an external control system and method for an injection molding machine special for in-mold lamination. Background technique [0002] Since the in-mold lamination process (using low-pressure injection molding) is more strictly controlled than ordinary injection molding, the mold structure is also more complicated. Ordinary injection machines cannot control subsystems such as the hot runner, mold opening and closing, and valve gates of the in-mold lamination mold. Generally, a dedicated low-pressure injection molding machine is required. However, the use of special low-pressure injection molding machines often has the problems of high cost, large space occupation, and poor openness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an external injection molding machine that is ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an external injection molding machine that is associated with the control system of an ordinary injection machine by developing an in-mold lamination process for the above-mentioned defects of high cost, large space occupation, and poor openness of the prior art. The control system and its implementation method are used to realize the special injection molding machine for in-mold lamination with low price, small space occupation and good openness
