The Optimization Study On Shutting Mould Structure Of All-electric Injection Molding Machine Based On Ansys

All-electric Injection Molding Machine is the main equipment of portoperation, and its complex dynamic response analysis and system reliabilityevaluation are major issues that the All-electric Injection Molding Machine facesin the development of large and high-speed. Due to its complex workingcondition, the All-electric injection molding machine sustains lots of complexdynamic impacts which will eventually cause the key parts and steel structure toemerge fatigue damage. So development on the law of the key parts’ stressdistribution and its fatigue life makes significant importance for the All-electricInjection Molding Machine.To solve the problem of the dynamic impulse response analysis and fatiguelife prediction about All-electric Injection Molding Machine, the papercomprehensives machinery, materials,mechanical and other related theories, thendo work characteristics and fatigue life prediction base on computersimulation.The main content includes as follows:Firstly,due to the parts on the route of the load bear complex impact of thedynamic load, so they are more likely to emerge fatigue flaw and damage,therefore, we take a research on working characteristic of the key parts and thesteel structure base on the related theory of mechanic.Use the finite elementanalysis method to analyze its typical operating conditions of the staticmechanical properties and take transient dynamic analysis to obtain thedangerous test points’ fatigue stress response curve. This is the precondition toestimate the machine’s lifetime.Secondly, based on the ANSYS software, the paper does static analysis on the key components of the electric injection molding machines, such as rod,speed changing box, front support and overall unit, etc. Especially on the frontsupport, we come to better design between two ideas, then do topologyoptimization design on it, it is good to meet system performance requirements.Thirdly, the paper introduces the related theory of the fatigue briefly.According to machine’s fatigue stress response curve, the paper takes advantageof Miner fatigue accumulating theory to estimate the fatigue life of theAll-electric injection molding machine.In the paper, the research on the working characteristic of the mouldsystem’s key parts and steel structure and the estimation of the All-electricinjection molding machine’ fatigue life will take some guiding significance in themaintenance of the machines, and its dynamic response analysis ideas andpredition method of fatigue life can be applied to other lifting machinery orconstruction machinery.
