Device and method for realtime controlling self-adaptive temperature injection-mould machine and its temperature-adjusting circuit

Abstract

The invention is concerned with the controller, the control method and the temperature controlling circuit of the of the self-adapting temperature real-time controlling plastic jetting-moulding machine that for the closed-loop control electric plastic jetting-moulding machine. It is: the controller consists of up-position machine for monitoring and the down-position machine for execution, the up-position machine and the down-position machine connects by communicating line, processes data information processing with central processing unit. The controlling method is: a. the selection of temperature signal; b. the pretreatment of the temperature signal; c. the rule base comparison of the temperature signal; d. the self-adapting adjustment of the control parameter; e. the outputting application of the controlling signal. The advantages are: can inhibit the effect of big lag effectively, with better stability and robustness; can conclude the experience of the temperature control of accumulation and the experience of the operator of the plastic jetting-moulding machine to be the rule base and the knowledge base, add the adaptive control of the parameter at the stage of temperature rise and temperature preservation in order to reduce the difficulty of using; the control precision of the charging basket static state and the working state is high, the produce is high quality and stabilization.

Description

technical field [0001] The invention relates to the field of temperature control of injection molding machines, in particular to a fully closed-loop controlled electric injection molding machine with adaptive temperature real-time control injection molding machine controller, control method, and temperature control circuit. Background technique [0002] With the further maturity of the plastic products processing industry, higher and higher requirements are put forward for the plastic machinery industry. In order to achieve the goal of high efficiency, precision and energy saving, people have carried out long-term exploration and put forward various improvement schemes. For example, the Chinese patent document discloses an automatic molding machine controlled by a programmable logic controller [Application No.: CN94190352.4], which includes a device for reading a sign provided on one side of a mould, the reading device Connected to a programmable logic controller which moni...
