Title Optimal Design of a Rubber Cylinder in Low Pressure Injection Molding

Abstract

Low pressure molding is a kind of new technology based on the traditional injection molding,which is mainly applied in automotive electronics、medical electronics、consumer electronics、aerospace electronics、IT industry.It has many advantages such as insulation、heat resistance、shock resistance、moistureproof、waterproof、dustproof and chemical resistance,etc.This paper mainly studies the optimal design of a rubber cylinder in low pressure injection molding.First,the general design of a rubber cylinder is determined,including design index、size、material、the quantities and size of the heat conduction grid;according to CAD and Solidworks,the part drawing and the 3D model are obtained.Then,according to ANSYS,the 3D finite element modeling of a rubber cylinder heating temperature field is established， the temperature field of melt adhesive and the melt volume at different time are obtained.Finally,according to the analysis of the simulation data and experiments result,the optimal data of the rubber cylinder is obtained.This optimal design turns out to be feasible,and the stable supply of melt adhesive,the determination of manufacturing time,the cost reduction are realised.
