A control system for an electric injection molding machine

Abstract

A control system for an electric injection molding machine, comprising eight function modules, i.e., a mold locking function module, an injection function module, a pressure maintaining function module, a glue extraction function module, a metering function module, a mold opening function module, a forward jacking function module, and a backward jacking function module. The eight function modules are provided with general interfaces, and are connected in series by means of the general interfaces. The connection order of the eight function modules is freely arranged and selected. The mold locking function module, the injection function module, the pressure maintaining function module, the glue extraction function module, the metering function module, the mold opening function module, the forward jacking function module, and the backward jacking function module consist of several accelerated / decelerated motion modules, respectively. The accelerated / decelerated motion module comprises an input side and an output side. The input side of the accelerated / decelerated motion module is used for inputting motion data and logical data, and the output side of the accelerated / decelerated motion module is used for outputting the motion data and the logical data. The control system is flexible and convenient to use, simplifies operations, and reduces maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of injection molding machines, in particular to a control system for electric injection molding machines. Background technique [0002] The electric injection molding machine started late in our country, and domestic injection molding machine manufacturers developed it while exploring, and its control system gradually improved from simple basic functions to today's complex multi-functional control system. The basic functions of the control system of the electric injection molding machine are: mold opening, mold locking, pressure maintaining, thimble jacking, thimble jacking back, injection in, injection back, and metering. The basic auxiliary functions are: temperature control, core out, core in, twisting teeth in, twisting teeth back, mold adjustment in, mold adjustment back, injection table in, injection table back, etc. [0003] The action sequence of a working cycle of the electric injection molding mac...

AI Technical Summary

Problems solved by technology

The cause of these problems step by step lies in the insufficient understanding of the control system of the electric injection molding machine in the early stage of the development of the electric injection molding machine.

This method can be done once and for all, but reconfiguring the system software architecture often takes a long time due to the heavy workload, and also requires a full understanding of the electric injection molding machine control system in order to be open, easy to maintain, and adapt to the future. Requirements for high-speed and high-precision injection molded parts

[0004] At present, the electric injection molding machine control system adds functions and improvements to the original software architecture built in the early stage of electric injection molding machine development, which has the problems of low development efficiency, difficult follow-up maintenance and high maintenance cost

At this stage, the electric injection molding machine control system needs to restructure the system software architecture, which has the problems of heavy workload, long time consumption, and uncertain openness

At this stage, the functional modules of the electric injection molding machine control system are dedicated links, without universal interfaces, and poor flexibility

Subsequent process improvements can result in heavy and complex programming

[0005] At this stage, the control system of the electric injection molding machine adds too many functions and threads to the original software architecture, and the stability of the entire program will also be affected

At this stage, the control system of the electric injection molding machine needs to restructure the system software architecture, and customer operations and usage habits will also be affected
