摘   要
本次设计的课题为Φ146.6的药瓶及其瓶盖的塑料模具的设计。药瓶的形状是腔大口小,要是采用普通的注射模设计,型芯将难以脱离。虽然可以采用变型芯,但那样会使模具成本大幅度增加,且设计难度比较大。因此药瓶模具为上吹型中空吹塑模具,采用嵌块式结构,铸造水路冷却,结构简单,耐用,便于更换部件,生产效率比较高。模具由动模板、定模板、切割环、模口嵌块、模底嵌块、密封垫板以及固定板等部件组成。瓶盖可以采用普同注射设计,但由于其内部有螺纹,不易采用强行脱模。因此瓶盖模具是两板式,采用旋转脱模的注射模具。该模具自动化程度比较高,效率比较高。该模具由定模板、动模板、支撑板、齿轮轴,圆柱齿轮、圆锥齿轮、齿条等一系列零部件组成。

Abstract

The program of this design is Φ the medicine bottle of 146.6 and the plastic pattern of its cap have design . the shape of medicine bottle is cavity big mouth little, if design , type core with ordinary injection mould will be hard slip away . may adopt though change type core, can but so make mould cost increase substantially, design difficulty just compare big. therefore the mould of medicine bottle is blow type hollow blow mould mould, adopt inlay piece type structure, casting waterway cool , structure simple, durable, change parts easily, production efficiency is ring and mould high fairly. mould from the fixed die board and board of movable mould , cut mouth inlay piece and mould base inlay piece, gaskets board as well as the etc. parts of fixed head form . cap may adopt general inject design together, but have thread because of its inside, do not be easy adopting force take off mould. therefore cap mould is two board type, adopt spin take off the injection mould of mould have . this mould automation level is mould high fairly, efficiency is  high fairly. this mould from fixed die board, the board of movable mould, gripper shoe, gear axle, cylinder gear, cone gear, rack and such a series of component composition.
Keywords: the fixed die board  board of movable mould  inlay piece  cool  spin take off
