摘要
Abstract
The fan shaped tee joint is a kind of fan-shaped cylindrical joint which has screw holes and shaped holes on the top,a variety of shaped holes on the side and bottom.By analyzing the product shape and the feasibility of mould structure,schemes was developed by adopting advanced hydraulic cylinder to strip off the screw hole and execute side corepulling,demoulding lag and taking product center as the mould parting surface.For the tee joint shape and 2 × φ 4.2 mm type hole,the inclined guide pillar slider parting and core pulling were used.The ejector sleeve type demoulding and bottom hole core-pulling measures were taken.Injection mould was set up as four groups of tee joint structure.The perfect mould temperature control system and the gating system were designed.The injection mould possesses the features of multiple groups,high efficiency,automation processing,which ensure mass production of fan shaped tees with high quality.关键词
