【摘要】 用材料力学的常规方法对矩形和圆形模框的厚度及动模支承板厚度进行了较详细的推导和计算，针对动模支承板的实际最大工作应力值常常大于常规公式计算值，采用两种方法为其强度的可靠性设计提供依据，即有限元法和增加支撑的措施，使其强度和刚度都获得明显改善。对已有的智能型压铸模ＣＡＤ软件菜单界面重新进行了改组和设计，加进了模板设计等模块，获得了较为完善的压铸整体结构——ＣＡＤ软件。设计的压铸模模块ＣＡＤ应用软件可以在计算机上完成模块设计的计算工作。更多还原

【Abstract】 Using the normal method of mechanics of materials,the authors have carefully deduced and calculated the thickness both of rectangular and circular metal mold—jacket and of movable mold support plateSince the practical maximum working stress for movable mold support plate is usually greater than the outcome of caculation,two methods,namely the finite element method and the measure of increasing support,are adopted to improve the strength and rigidity of movable mold support plateAfter adding a module of mold—board desigh to the existing Intelligence Die Casting CAD software,the authors have restructured the original menu of die casting and got a more perfect die casting CAD softwareThe improved die casting CAD softwer can accomplish the computation task of mold —board design in computer更多还原
