| Plastic molding injection molding is one of the most important processing method, which are widely applied to the national economy in all areas. Along with the wide application of plastic products, plastic products to customer quality requirements of more and more is also high. For how to use plastic product injection molding process optimization technique for better injection molding process conditions studies will become more and more important. Injection molding CAE technology can help engineers to plastics molding process optimization, to reduce repeated the number of mold testing molds, shortened product production cycle. But this can only get a more reasonable the plastic injection molding process and can’t get the injection molding of the optimum process. Therefore, how to injection molding CAE technology from the results of the extract the effective information to assist process optimization, to improve the quality of plastic products has great significance.In the subject of study,the Plastic pump body is submerged pump of one of the parts. Resin type pump body parts structure design of the pump to the quality of the performance and life will have a direct impact. This subject first according to primitive conditions, consult the relevant documents of the pump body parts of the product structure design. And then according to the design drawing, in UG software to its accurate in modeling, and the type of the pump body parts CAD model into Moldflow.The combination of resin type pump body parts a feature of structure and the software recommended Moldflow theory best gate location analysis, design the four gating system solutions. And for its4kinds of schemes respectively, this paper analyzes the resin type pump body parts to determine the actual pouring system solutions.According to the pump body type resin the injection forming of process parameters the scope of orthogonal test design, the orthogonal experimental Moldflow in each scheme for simulation and analyzes the simulation results. Then use the simplex method to improve product type pump body parts molding process parameters optimization analysis, so as to determine the type pump body parts the biggest warping deformation quantity and comprehensive weighted score of the values of the injection molding process parameters of the best value range.This article, on the pump body parts of the product type gating system scheme and the best injection molding process parameters, and based on the cooling system design of the pump body parts of the product of the mould. Thus,the enterprise to shorten the production period, and enhance the efficiency of the die design. |
