With the successive development of new materials and composite materials,the automotive industry has ushered in a transition period between traditional manufacturing and lightweight manufacturing.It is also a survival challenge that major auto brand manufacturers have to transform.The lightweight of the car is,in short,based on keeping the performance of the vehicle unchanged,as the overall weight of the car is reduced,the power loss of the car will be reduced to a certain extent,fuel efficiency will be improved,and exhaust emissions It will also be improved,and it will be easier to meet the standard value of automobile exhaust emissions stipulated by national policies.According to relevant experiments,the fuel efficiency of automobiles increases with the reduction of overall vehicle weight;total fuel consumption and fuel consumption decrease with the reduction of overall vehicle weight.The development of industrial technology is changing with each passing day,and the metal parts of automobile parts are increasingly replaced by plastic parts.Extrusion blow molding(EBM)hollow polymer products using nylon and glass fiber(PA66)as raw materials have increasingly broad application prospects in the chemical and automotive industries,and the demand for EBM products is also increasing.The plastic gas storage tube of the automobile turbocharger studied in this article is the plastic part of automobile parts produced by the extrusion blow molding process.The injection-molded part containing the air inlet and outlet on the gas storage tube is embedded in the core pulling mechanism of the mold.Make the integrity of the entire pipeline better.Based on the UG software,the mold of the turbocharger plastic gas storage tube is structurally improved.When designing a hollow blow mold,the layout design of the cooling system is taken into consideration to a large extent.Impact on cooling production efficiency.By analyzing the factors affecting the cooling system,the design principles based on the layout of the cooling water circuit,the influence of the moldmaterial parameters on the cooling system,and the common cooling water circuit layout types.Based on the Flow Simulation fluid and heat coupling analysis plug-in and experimental parameters in Solidworks,the finite element analysis of the cooling system circuit designed in this subject is performed.By comparing and analyzing the cooling effect under various influencing factors of the cooling system,the temperature change curve and distribution cloud diagram of the research object and the mold and waterway during the production cooling cycle are obtained,and the optimal cooling system plan of the mold is finally obtained through response surface test design.In the process of extrusion blow molding,the wall thickness distribution of the final molded product is affected by many process parameters,such as parison wall thickness,diameter and temperature,mold temperature,inflation pressure,and material parameters.The shape of the research object of the turbocharger plastic gas storage tube is relatively complicated.During the production process,the mold clamping process of the mold is matched with the pushing-in of the core drawing mechanism,which affects the product molding effect.Workflow software polyflow plug-in was used to study the influence of the molding process on the uniformity of the wall thickness distribution of the turbocharger gas storage tube.The response surface method was used to optimize the wall thickness distribution of the product.The research process of this topic combines design,analysis,technology and production,and studies the process optimization and mold cooling system optimization in the process of extrusion blow molding of plastic gas storage tubes for automotive turbochargers,which has a high practical value for guiding production.The results of the research and analysis can obtain the technical parameters of the gas storage pipe with good molding effect and uniform wall thickness distribution of the part,reducing the number of mold repairs,reducing the production cost to a certain extent,and improving the production efficiency.It is an extrusion blow molding of complex non-axisymmetric plastic parts.Development provides theoretical basis and technical guidance.
