Description

Injection molding process control method of multicolor injection molding machine

Technical Field

The present invention relates to a method for controlling an injection molding process, and more particularly to a method for setting an injection molding process according to different mold requirements.

Background

Before the injection molding machine performs the injection processing operation, please refer to fig. 1, the basic control flow of the required setting includes status monitoring S100, temperature setting S101, mold opening and closing setting S102, front side injection/charging setting S103, ejection/blowing setting S104, function/time setting S105, production control S106, neutron setting S107, material cleaning injection setting S108, and rear side injection/charging setting S109, so it needs to be clicked in sequence to perform the setting respectively in accordance with the display interface of the control panel. For example, entering the state monitoring page to view the state of the machine during normal operation, entering the temperature setting page to change the heating setting, entering the unlocking setting page to change the settings of locking, unlocking and adjusting the mold, entering the front side injection/charging setting page to change the settings of injection, pressure maintaining, charging and ACC selection, entering the ejection/blowing setting page to change the settings of ejection middle support, rotation, front support, rear support, blowing and other function setting options, entering the function/time setting page to change the function switch window, the settings of front and rear side prepressing and time settings, entering the production control setting page to change the settings of production record and quality control, entering the file management setting page to provide the operator with the molding parameters set by all operators during the production of the relevant mold, entering the neutron setting page to set the action options of the neutron according to the set position or the discharge of the glue gate valve into the mold closing end, entering the temperature setting page to change the heating setting, entering the unlocking setting page to change the settings of the mold opening, entering the function, Enter the setting page of the material cleaning/injecting seat to proceed the setting of material cleaning selection, frequency, seat back, injection and material feeding, etc., and enter the setting page of the rear side injection/material feeding to change the setting of injection, pressure maintaining, material feeding and ACC selection. From the above-mentioned process, after the existing injection molding machine completes the setting of the basic control options for the object and mold to be injection molded, if the object and mold to be injection molded are to be changed, the object and mold to be injection molded must be clicked again one by one and enter each basic control page to complete the setting.

Accordingly, the inventor of the present invention discloses a method for improving the control of the injection molding process, and applies and approves the method for controlling the injection molding process of a plastic injection machine in taiwan bulletin No. I261022, as shown in fig. 2, which is to add the control options of the automatic process setting S206 in the status monitoring S200, the temperature setting S201, the mold opening and closing setting S202, the front side injection/charging setting S203, the ejection/blowing setting S204, the function/time setting S205, the production control S207, the neutron setting S208, the clean injection setting S209 and the rear side injection/charging setting S210 of the standard manufacturing process, so as to select and correct the entire process control by the automatic process setting page 1 in accordance with the operation options to be set (as shown in fig. 3), so that the operation of the plastic injection machine and the user can directly complete the correction and setting according to the characteristics of the mold and the product during production, thereby effectively improving the efficiency. However, the automatic flow setting S206 cannot be applied to an injection molding machine having two or more colors, and there is no commonality in the use of the automatic flow setting S206.
