Intelligent management system for gear metal powder injection molding

Abstract

The invention belongs to the related technical field of gear manufacturing, and discloses an intelligent management system for gear metal powder injection molding, which comprises a feature library for storing feature parameters of gear products; a knowledge base which is used for storing whole-flow information of a gear product design process; a rule base which is used for storing influence rules of process parameters on product quality in the gear product forming process; and a data storage module which is used for inputting the input feature parameters of the new gear product into the feature library, if the new gear product is a successful case, storing the whole-process information of the new gear product into the knowledge library, updating the influence rules in the rule library, and if the new gear product is a failed case, visually displays the characteristic parameters which are the same as the successful case and different from the successful case. According to the method, the characteristic parameters, the technological process and the like in the gear metal layer injection molding process can be effectively managed, and the design and production efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field related to gear manufacturing, and more specifically relates to an intelligent management system for metal powder injection molding of gears. Background technique [0002] Gears are the most common transmission parts used in mechanical equipment. They have the characteristics of complex shape and high precision requirements. Metal injection molding technology not only has the same complex shape and high precision as the products obtained by plastic injection molding, but also has the same physical properties as forgings. , chemical and mechanical properties, especially suitable for small gear manufacturing. At present, in the gear metal powder injection molding industry, mold design, feeding design, and process design are the key parts. The existing general technology takes more than 40 days from design to production of a pair of metal powder injection molding gears. The reason is that gear metal powder The...

Problems solved by technology

At present, in the gear metal powder injection molding industry, mold design, feeding design, and process design are the key parts. The existing general technology takes more than 40 days from design to production of a pair of metal powder injection molding gears. The reason is that gear metal powder The injection molding process is complex, including: part design, feeding design, mold structure design, structure simulation, process simulation, mold manufacturing, injection process, degreasing process, sintering process, etc. Each link has a large number of parameters, and each process There is an inheritance relationship between the parameters, even experienced designers need to make repeated "trial and error", which is very time-consuming and laborious, the design takes a long time, and the design efficiency is low
