Embodiment Construction

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] A pair of molds, the injection plastic is ABS, the defect type is "under-injection", and the process parameter is "injection pressure".

[0055] figure 1 It is an overall block diagram of the embodiment of the present invention, illustrating the overall implementation method and process of the present invention. In the part of knowledge acquisition, the expert knowledge of plastic injection is collected and sorted out by the method of knowledge engineering, and the fuzzy if-then rule set of "under-injection" and "injection pressure" correction is formed, and its form is as shown in the example of fuzzy if-then rules in the content of the invention At the same time, a knowledge base of defect priority is formed to determine which defect should be corrected first when multiple defects appear at the same time. Both the fuzzy rule base an...

Abstract

The present invented method consists of 1, establishing expert knowledge base and blur rule base; 2, based on said knowledge base and blur rule base, utilizing fuzzy reasoning technology establishing fault modification fuzzy model in injection process; 3, according to fed die setting process technological parameter, jet molding piece fault type and fault level, reasoning and calculating to obtaintechnological parameter correction. The present invention also obtains a jet molding unit. Said invention has advantages of quick adjusting technological parameter, fast modifying jet molding piece fault, and raising jet molding piece quality.

Description

technical field [0001] The invention relates to a plastic injection molding process, and more particularly to an intelligent correction method and an injection molding machine for the defects of injection molded parts in the plastic injection process. The expert rule base is used to establish a fuzzy inference model for defect correction of injection molded parts, and the adjustment amount of process parameters can be obtained by reasoning, so as to realize the correction of product defects in the process of plastic injection. Background technique [0002] Plastics have the characteristics of low density, light weight, good insulation performance, low dielectric loss, high chemical stability and good wear resistance, and are widely used in various fields such as industry, agriculture, construction, packaging, national defense and daily life. The growth rate has jumped to the top of the four major industrial materials (plastics, steel, wood and cement), and it is one of the f...
