摘要
具有型芯的模具,在注射压力的作用下,将使型芯产生一定偏移,引起塑件变形。分析注射压力对模具型芯偏移量的影响,根据材料力学理论基础,推导出圆形截面型芯和矩形截面型芯最大弯曲变形的计算公式,为合理确定型芯尺寸提供了理论依据。
In the function of injection pressure,the mould which has core will produce a little core offset and cause plastics deformation. The influence of the injection pressure on mold core offset was analyzed. According to the theoretical base of material mechanics, formulas of the maximum bend deformation to circlcsection core and rectangle-section core were calculated, providing theory basis for deciding the core dimension rightly
